  • Windows 8 Doesn't Shutdown Properly With Fast Start-Up Enabled

    - by Patrick
    While Fast start-up is enabled, on turning the computer off (shutdown) the computer idles for about 5min after logging out/screen turning off. It then turns off. On returning into Windows I receive the error message saying Windows didn't shut down properly. Hibernate works fine, and I am told this shouldn't be the case - If one doesn't work, neither should. It works when both Fast start-up is enabled and disabled, as does restart and sleep. Windows is installed under UEFI. The UEFI ultra fast boot option for my motherboard cannot be enabled as my GPU doesn't support some UEFI GOP tech. As far as I know, not related to windows fast start-up, but thought it was worth mentioning. To clarify, if this: http://www.eightforums.com/tutorials/6320-fast-startup-turn-off-windows-8-a.html is enabled, the computer does not shut down properly. EDIT: Some more information on the matter: Formatting didn't fix the issue. Still fails regardless of drivers installed. Hardware was purchased ~6months ago. Running a good SSD. Event viewer Always these two messages in close succession: Error (event ID 6008): The previous system shutdown at 7:45:21 PM on ?27/?10/?2012 was unexpected. Critical (kernel power, event ID 41): The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. Upon installing WPT as suggested below to figure out what was happening during shutdown, and running the cmd xbootmgr -trace shutdown -noPrepReboot -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMP Windows fast start-up is now working consistently. Still works upon uninstalling WPT. This is the only change to occur on the computer. Nothing else has bee installed/uninstalled, no Windows Updates, nothing. Windows fast start-up did not work prior to installing WPT and running the cmd (made sure I tested).

  • Troubleshooting a Windows 7 PC that wouldn't sleep

    - by NPE
    I have a new Windows 7 PC that wouldn't sleep (not just automatically, but also when specifically told to). The screen goes black momentarily, but within two seconds the machine comes back as if nothing has happened. I tried powercfg energy. This produces some errors quoted at the bottom of this post, plus some warnings about timer resolution. There are no USB devices connected other than wireless keyboard + mouse (Logitech MK250); I tried unplugging them to no effect. The motherboard is Asus P7P55D-E. powercfg lastwake says "Wake History Count - 0", which I take to mean that it never actually went to sleep. I dual boot into Ubuntu, and was having exactly the same problem on the Linux side. That turned out to do with USB 3.0, which I've now disabled in the BIOS. This has solved the problem on the Ubuntu side of things, but made no difference to Windows 7. Any suggestions? Suspend:USB Device not Entering Suspend The USB device did not enter the Suspend state.

  • Why does hiberfil.sys come back from the dead on Windows 7?

    - by Corey White
    I have Windows 7 running on a small (40GB) partition, with 4GB ram. This means that the hiberfil.sys file created by Hibernate takes up a significant portion of the available diskspace. I would like to remove it. I am aware that I can disable Hibernate and remove hiberfil.sys by entering powercfg -h off in an elevated command prompt. This works -- the file is immediately removed, and after doing so, the HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\HibernateEnabled key is (correctly) set to 0. However, the next time I reboot the PC, hiberfil.sys returns from the dead, Hibernate is reenabled, and that registry key has returned to 1. I'm pretty much at my wits' end with this. Almost everything I can find online related to removing the hiberfil.sys file simply suggests using powercfg to turn off hibernation, and that appears to work for just about everyone. But it just keeps coming back for me! (Like a vampire, sucking up my disk space.) I did find one other thread from someone who seems to have had the same issue, but none of the suggestions there worked for the original poster (or for me). Still, I have tried everything listed there, including: Disabling hybrid sleep Disabling Hibernate through the command prompt, through the Power Options GUI, and through both (in both orders) Manually changing the HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\HibernateEnabled key Pretty much everything else I can think of! I do want to reiterate that I have no problem removing the file -- that works great. It just comes back after every reboot. I'm about ready to throw in the towel and just run a script on login to disable Hibernate each time, even though that seems like a crazily hacky "solution" . . . but I was hoping someone here could suggest something else, first. Thanks!

  • What does this diagnostic output mean?

    - by ChrisF
    I recently had a fault with my broadband connection. It turned out to be a fault with the ISP's or teleco's equipment. My ISP posted this diagnostic, but while I understand it in general, I'd like to to know more about the details. I'm assuming that ATM means Asynchronous Transfer Mode and PPP means Point to Point Protocol.

  • raid 0 data recovery?

    - by Fred
    HI All, I have two identical seagate 7200.9 500Gb drives confiured as a RAID 0 spanned disk in windows. One of the drives has lost power and wont spin up at all. I know this normally means death for the data on both drives but i have a cunning plan.. DISK 1 - NO POWER RAID 0 DISK DISK 2 - FULLY FUNCTIONAL RAID 0 DISK DISK 3 - FULLY FUNCTIONAL SPARE DISK Copy the working drive (disk 2) data to a third 500GB DISK (disk 3), remove the logic board from the working disk (disk 2) and replace it with the non working logic board on the broken drive (disk 1) , then hopefully recreate the RAID 0 with disk 1 and disk 3, just long enough to get the data off it. Hope this makes sense, here are my questions: Windows disk manager atm recognises disk 2 but wont let me access it in anyway, therefore copying the data off it (or getting a disk image) cant be done in windows. Does anyone know of any software (in linux or self booting) that would allow me to access this disk? Anyone know of any software that will recreate the spanned drive off two disk images Am i missing any key information that means i definitely shouldn't even bother starting this, i know its a long shot anyway but its worth a try unless i definitely cant do it. The irritating thing is that i am sure its a logic board failure on disk 1 as it simply wont power up at all, suddenly no signs of life, so i am sure the data is intact! Any help would be really appreciated! Thanks

  • The USB mouse sticks in Windows 7 after automatic attempt to fix the boot

    - by chelder
    Avast Antivirus asked me to delete a probable virus and to restart to perform a checking. I had to stop the checking at the middle of the procedure as I needed the computer. It was imposible to turn off the computer pushing the power button (as it entered in suspension mode, no matter how long I kept pushed the power button). I removed the battery as the only way to restart the computer. Windows 7 said that there is a problem to iniziate Windows. Windows 7 tried to fix the problem without success. Windows 7 started after that though. Everything is OK but the USB mouse. The USB mouse sticks and freezes each couple of seconds more or less. The tactile mouse (PS2) works well. I googled for solutions but the posible solutions didn't work for me. What happened? How could I fix it without formatting and reinstalling everything? UPDATE: this is what I did: Change the mouse from one usb port to another Test another mouse Set the number of cores of the CPU manually with msconfig Power management: not disable usb ports Check hard disk errors

  • How does one skip "Windows did not shut down successfully" in Win7-64?

    - by XenonofArcticus
    Migrating an app from an expensive and unreliable dedicated embedded x86 box running WinXP-embedded to COTS hardware (Dell E6410 laptop) running normal Win7-64. At this time, it's not feasible to deploy using Windows 7 embedded. The problem is, that the system is still sort of "embedded". The power could shut off at virtually any time without prior warning. We've stripped the OS down and removed the battery capability so that it will power down as desired. The app never writes to the disk, so it's not like we're going to corrupt anything terribly. The system is essentially idle after our app is up and running (with the exception of some computation, graphics, and TCP/IP and serial communications) so the OS enters a pretty stable state rather quickly. After a power-loss however, it rightly complains that Windows did not shut down successfully and presents the user with the Windows Error Recovery text screen. If left alone, it does eventually move on booting just fine, but we'd like to skip that step if possible. WinXP-embedded is designed to do this automatically, so I know it's possible. I've looked at the Kernel Switches but I didn't see anything documented for "Skip Windows Error Recovery". I've also read extensively on the startup process: http://homepage.ntlworld.com./jonathan.deboynepollard/FGA/windows-nt-6-boot-process.html I know I can disable the auto chkdsk in the registry, but that's not the same thing either. So, how do I streamline the boot process to not hassle the user about a situation that will be the regular normal situation?

  • What is the peak theoretical WiFi G user density? [closed]

    - by Bigbio2002
    I've seen a few WiFi capacity planning questions, and this one is related, but hopefully different enough not to be closed. Also, this is related specifically to 802.11g, but a similar question could be made for N. In order to squeeze more WiFi users into a space, the transmit power on the APs need to be reduced and the APs squeezed closer together. My question is, how far can you practically take this before the network becomes unusable? There will come a point where the transmit power is so weak that nobody will actually be able to pick up a connection, or be constantly roaming to/from APs spaced a few feet apart as they walk around. There are also only 3 available channels to use as well, which is a factor to consider. After determining the peak AP density, then multiply by users-per-AP, which should be easier to find out. After factoring all of this in and running some back-of-the-envelope calculations, I'd like to be able to get a figure of "XX users per 10ft^2" or something. This can be considered the physical limit of WiFi, and will keep people from asking about getting 3,000 people in a ballroom conference on WiFi. Can anyone with WiFi experience chime in, or better yet, provide some calculations for a more accurate figure? Assumptions: Let's assume an ideal environment with no reflection (think of a big, square, open room, with the APs spaced out on a plane), APs are placed on the ceiling so humans won't absorb the waves, and the only interference are from the APs themselves and the devices. As for what devices specifically, that's irrelevant for the first point of the question (AP density, so only channel and transmit power should matter). User experience: Wikipedia states that Wireless G has about 22Mbps maximum effective throughput, or about 2.75MB/s. For the purpose of this question, anything below 100KB/s per user can be deemed to be a poor user experience. As for roaming, I'll assume the user is standing in the same place, so hopefully that will be a non-issue.

  • Video card not detected in POST on initial boot.

    - by Jeff M
    I have a minor problem with my desktop computer after cleaning it out for dust. When I first boot up the computer, the video card does not get detected so I can't see anything. In POST, I'm getting the "can't detect video card" beeps. The boot sequence continues normally, just without video. However, if I restart it (using the restart button) anytime after POST, it would boot up normally. I have no reason to think that the motherboard, video card or PSU got damaged in the process. It was working fine before, works fine after resetting. Took all the necessary precautions while cleaning. On the initial boot, I can hear the video card's fan power up but immediately power down and try again one more time only to fail. After the beep, resetting gets everything running and sounding normally. I've reseated the card a couple of times and reset the BIOS but doesn't seem to help. I'm hoping I won't have to take it out and remove and reinstall everything again. Does anyone recognize these symptoms to know exactly what the problem is? My guess is that the video card isn't getting enough juice initially to be running stable to be detected. I just don't know what I did (or didn't do) to get it to be in this state. It's not a high priority thing for me at the moment, just means I have to always reset it after initially turning it on but will eventually remove everything and reinstall if it comes to that. I don't think the specs are relevant here but just in case, here's the relevant stuff: Motherboard: Gigabyte P35-DS3P Video: EVGA GeForce 8600 GTS PSU: Antec True Power Trio 650W Built ~2 years ago, still running well

  • Wireless keeps shutting off in Windows 7

    - by Nathan Adams
    I have Windows 7 Ultimate 32bit installed on a Dell Latitude XT Tablet and for the life of me I can't figure out this really weird problem. The symptom is that the Wireless will disconnect from the AP and if I tell it to scan again, it says there are no APs in the area. I do have another wireless card in the laptop and if I disable the first one and enable the second, I am able to get onto the wireless however if I want to use the first card again I have to restart. I tried enabling/disabling the device, nothing will kick start the wireless again in the first card without a restart. I even tried different drivers. So, it seems it is random but it does occur more often when there is increased network activity (ie downloading a large file). The laptop doesn't seem to be overheating. I have tried the following: Under "Change Advanced Power Settings" for the current power profile, I set the "Wireless Adapter settings" to "Maximum Performance". Under device manger, I went to the card in question, and went to the advanced tab and set the "Power Saving mode" to "MAX_PSP" Both cards I have seem to exhibit the behavior after awhile. Both models of those cards are: Dell Wireless 1505 Draft 802.11n WLAN Mini-Card Gigabyte GN-WS30N 802.11n mini WLAN Card Has anyone have any ideas or ran into this before?

  • Hardware issue, bsod with windows xp irq and strange messages with ubuntu

    - by JP Hellemons
    I have an old Acer T160 and it used to run Windows XP. But I keep getting random BSOD's. I keep seeing IRQ conflicts. I tried to run ubuntu, which runs and keeps running. But sometimes is not responding. Also there are these popups at ubuntu 12.04 that my network cable (which is onboard) is unplugged. But I have no cable in it! and have an usb dongle for wifi. which also seems unstable. have to (auto)reconnect sometimes. So my question is: is it my mobo, power supply or something else? FYI: I had an dvd-rw station which did not open properly, so unplugged the ata and power, als removed the second harddrive. now only have sata harddrive. also removed the extra video card (ati sapphire x1600 pro) so use only onboard video now and still have these issues. EDIT Update: will try with a new PSU (power supply unit of 400watt) the old (factory) one was 300watt. and will use a usb drive which has 12.04 ubuntu on it (made with unetbootin) to format everything and re-install ubuntu. (so also delete mbr partition) will update the day after tomorrow.

  • Virtualize SBS 2003 - P2V vs migrating to new VM

    - by jlehtinen
    I need to virtualize a SBS 2003 server in my work environment. I need some tips on what people think is the best way to proceed. Background: The SBS 2003 server is the primary DC for the domain and also hosts FTP, RRAS(VPN), DNS, and file shares. Exchange is NOT used, neither is SQL server. DHCP is done via a firewall appliance. I have added a Server 2003 VM to the domain and promoted it to the DC role. AD/DNS is replicating here correctly. This was mainly done to provide fault-tolerance to the domain, I was not intending to make this VM the primary DC. I've already asked about buying upgraded licensing for Server 2008/2012 but was refused due to cost. Options: I see (at least) two routes I could take to complete this. From what I've read option 2 is the "preferred" method, but there's a few steps where I'm not clear on what to expect. Option 1.) P2V the primary DC Power off primary DC Power off secondary DC (to prevent USN rollback in case P2V has issue) P2V (cold clone) primary DC Boot new PDC VM Allow new hardware to detect Remove old NIC hardware from device manager Assign old IPs to new virtual NICs Reboot PDC VM, confirm connectivity and no major issues Power on secondary DC, confirm replication Option 2.) Create new VM, transfer roles, remove original DC from domain Create new VM, install SBS 2003 Do I need the original SBS install discs for this? MS migration doc mentions this. Add VM to domain, promote to DC role Does this start 7 day timer where two SBS servers can be in same domain? Set up RRAS on new VM Set up IIS/FTP on new VM Move file shares to new VM Transfer FSMO roles to new VM DC dcpromo original primary DC out of domain

  • Dell Vostro Desktop error

    - by goldenmean
    Faced a strange situation at work today. We have people sitting at a table on opposite sides, with power cables underneath the table. This morning when the person sitting opposite to me banged his feet on ground, it disturbed the power cable to my PC and it turned-off. So when I turned it on, it says, "No boot device found" Press F1 to setup or F5 to perform test... There was no physical impact/crash/fall of the desktop cabinet, which could have crashed/damaged the hard disk physically. EDIT: The OS is Windows 7 So I tried to recognize it in the Bios setup, but even there it could not find the SATA disk that is connected to this machine. So then I opened the cabinet, removed the power supply and plugged it back again. Tried to reboot, same error, "Boot device not found" It is not recognizing the hard disk. Any ideas about what might be wrong? Hard-disk crash, OS Crash(But it doesn't even go to the point of loading the disk after the initial Bios execution, so doubt this...) Any pointers about how I should proceed to troubleshoot/solve this error are welcome.

  • Building My First Computer And Suprise It Isn't Working

    - by BobbShots
    I've had many years of experience working on and around computers, but this was my first foray into building one completely from scratch. So far that foray has been a disaster. My rig is completely assembled, and on its maiden power-up plus many power cycles I noticed three things: There were a few beeps from the BIOS POST upon powering up the first time, but I wasn't paying attention completely to the sequence. However, every time after that there are 0 POST beeps, even after taking off all hardware except the CPU and MB. There was no video being sent to the monitor. I run a HDMI cable from my video card to the monitor. The video card was LOUD. My card is a Sapphire Radeon HD 5870 which is known for not only being a powerhouse, but being pretty quiet. A few times during my power cycles it ran a lot quieter, but most of the time it was just super loud. Can anyone provide help for any of these issues? My MB, CPU, and Video Card are: MB: ASUS P6X58D Premium LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel Motherboard CPU: i7 920 Video Card: Sapphire Radeon HD 5870

  • break Folder Protection, Folder Guard Lock or Folder in Windows XP?

    when I'm making a new partition by the partition magic. Then all of a sudden power failure. Unfortunately because my computer is not equipped with UPS (Power supply Uniterruptible), my computer finally died, too. When power is restored, I tried to turn on the computer. Suddenly my computer can not boot normally into windows. Option through safemode and others all I've tried. The result fails, can not boot at all, into safe mode also can not. And I know the cause. Partition Magic did not finish the work and stopped in the middle of the road and cause the transfer of data files or stopped, finally file2 any default windows were destroyed as well. Unfortunately my important data I store in my document. Finally, I take my hard drive to a friend. Hopes to open a computer hard drive through friend, at least I could save my important data, and then I can install window again by reformatting my hard drive is first. I read the hard drive in explorer my friend, complete with their data, but the data of my important data in my document can not get to go because it requires administrator privileges or the original user's default start my windows (my computer) to open my document folder tersebut.Ini actually very similar to the work or Folder Protection Folder Guard. result I was disappointed and almost desperate to get back my important data is. how do i break Folder Protection, Folder Guard Lock or Folder in Windows XP?

  • Installing 64-bit Ubuntu Server 12.04 LTS, on a VM with VMWare Player, on a 64-bit Windows 7 PC

    - by WannaBeAGeek
    I'm trying to create a VM, using VMWare Player, with an ISO image of Ubuntu Server 12.04 (LTS). The machine I'm doing the installation on has an Intel(R) Core(TM) i5 CPU, and runs 64-bit Windows 7 I managed to create the VM (gave username, password, configured network etc), but I can't install Ubuntu Server. First I get this alert : Binary translation is incompatible with long mode on this platform. Disabling long mode. Without long mode support, the virtual machine will not be able to run 64-bit code. For more details see http://vmware.com/info?id=152. When I click OK, I get another alert : This virtual machine is configured for 64-bit guest operating systems. However, 64-bit operation is not possible. This host supports Intel VT-x, but Intel VT-x is disabled. Intel VT-x might be disabled if it has been disabled in the BIOS/firmware settings or the host has not been power-cycled since changing this setting. (1) Verify that the BIOS/firmware settings enable Intel VT-x and disable 'trusted execution.' (2) Power-cycle the host if either of these BIOS/firmware settings have been changed. (3) Power-cycle the host if you have not done so since installing VMware Player. (4) Update the host's BIOS/firmware to the latest version. For more detailed information, see http://vmware.com/info?id=152. Then, when I click OK, my VM exists, and I get back to the VMWare Player home screen. I don't know much about hardware and virtualisation, so there might be some necessary info I'm not giving. Please don't hesitate to let me know what is missing in my post, for finding solutions. Thanks :)

  • Short, intermittent USB port timeouts

    - by jacobsee
    I have a data acquisition application controlled by a Windows PC. I am using an Intel Desktop Board DH67CL motherboard. This has 6 USB2 ports along with 2 of the new blue USB3 ports. The DAQ instrument connects via USB to the computer. Roughly once every day or two there is a short communication glitch with the USB that causes the instrument to disconnect briefly and then reconnect. This is logged so I know whenever it happens. Occasionally it will cause the data acquisition to stop. I've verified that the glitches will go away if I use the USB3 ports, or if I use a PCI add-on card with USB ports. So it seems that there is something going on with these built-in USB2 ports on this motherboard. I haven't yet had a chance to test with other motherboards. My question: what could be causing these glitches and how to get rid of them for this board, or is there a better motherboard to use? We have standardized on the DH67CL because it's inexpensive, has 3 PCI slots that we need, and is readily available. We don't need the power of higher-end server boards but reliability is important. Thanks. Update: This problem has been reproduced many times on different hardware, though we always use the same model of motherboard (DH67CL) and power supply (Antec EA-430D). I don't think the power requirements are very high but will check on that.

    Yesterday I was trying to connect a Viewsonic Projector to my Samsung RC420 laptop... I followed this steps: I Plugged the Projector to a power source, in parallel I did the same thing with the laptop. Then I turned on the laptop, but not the Projector (this one turns a bright light when is connected to a power source). I put the VGA Cable to the Projector (this one being still turned down) and then when I was getting close to the VGA port of the Laptop... BAM! A big spark appear between the port and the cable! Immediately the whole electricity of my floor went off. A part of the port in my laptop kind of... melted down. It seems to be where the spark started. The same thing happened to the part of the cable involved. Now I'm using the laptop, and it seems that there is no problem in it, I haven't connect anything to the VGA port yet. And the projector is still working to, well... it turns on, and I haven't connect anything yet too. The projector was connected to the power source by a homemade electric extension.

  • How does one skip “Windows did not shut down successfully” in Win7-64?

    - by XenonofArcticus
    Migrating an app from an expensive and unreliable dedicated embedded x86 box running WinXP-embedded to COTS hardware (Dell E6410 laptop) running normal Win7-64. At this time, it's not feasible to deploy using Windows 7 embedded. The problem is, that the system is still sort of "embedded". The power could shut off at virtually any time without prior warning. We've stripped the OS down and removed the battery capability so that it will power down as desired. The app never writes to the disk, so it's not like we're going to corrupt anything terribly. The system is essentially idle after our app is up and running (with the exception of some computation, graphics, and TCP/IP and serial communications) so the OS enters a pretty stable state rather quickly. After a power-loss however, it rightly complains that Windows did not shut down successfully and presents the user with the Windows Error Recovery text screen. If left alone, it does eventually move on booting just fine, but we'd like to skip that step if possible. WinXP-embedded is designed to do this automatically, so I know it's possible. I've looked at the Kernel Switches but I didn't see anything documented for "Skip Windows Error Recovery". I've also read extensively on the startup process: http://homepage.ntlworld.com./jonathan.deboynepollard/FGA/windows-nt-6-boot-process.html I know I can disable the auto chkdsk in the registry, but that's not the same thing either. So, how do I streamline the boot process to not hassle the user about a situation that will be the regular normal situation?

  • Is it a good Idea to switch to a SSD to use less battery?

    - by Walter Maier-Murdnelch
    I am thinking of buying a SSD for my laptop, mainly for the purpose of extended operating time when running on battery. At the moment I use a Hitachi HTS545032B9A300 (320GB) (Datasheet) as main drive and a Seagate Momentus 5400.3 120GB as secondary drive. I dualboot Windows and Linux but I don't need the windows partition any longer, a 120GB SDD would be more than sufficient space-wise. Speed is not an issue for me, I make heavy use of tmpfs (ramdrive) within Linux and transfers of bigger files are mainly through some network filesystem anyways, thus a cheaper SSD should do. For the purpose of comparison I chose the OCZ Vertex Plus 120GB. Power consumption always is a big promotional thing the industry uses to make me want to buy their SSDs, some sheet on the OCZ page provides an astonishing comparison of desktop HDDS and SSDs. The numbers I got comparing my laptop HDD and their SSD were not really astonishing any longer. Hitachi 320GB HDD: Startup (W, peak, max.) 4.5 Seek (W, avg.) 1.7 Read / Write (W, avg.) 1.4 Performance idle (W, avg.) 1.3 Active idle (W, avg.) 0.8 Low power idle (W, avg.) 0.5 Standby (W, avg.) 0.2 Sleep 0.1 OCZ 120GB SSD: 1.5W active 0.3W standby I see that there are differences, but actually they don't seem that high as I though they were. And compared to the power consuption of the rest of my system I wonder if it makes a difference at all. Have I just taken the wrong look at the whole thing or may I be better off to buy another battery for my laptop?

  • Gigabit network limited to 25MB/s by CPU. How to make it faster?

    - by netvope
    I have a Acer Aspire R1600-U910H with a nForce gigabit network adapter. The maximum TCP throughput of it is about 25MB/s, and apparently it is limited by the single core Intel Atom 230; when the maximum throughput is reached, the CPU usage is about 50%-60%, which corresponds to full utilization considering this is a Hyper-threading enabled CPU. The same problem occurs on both Windows XP and on Ubuntu 8.04. On Windows, I have installed the latest nForce chipset driver, disabled power saving features, and enabled checksum offload. On Linux, the default driver has checksum offload enabled. There is no Linux driver available on Nvidia's website. ethtool -k eth0 shows that checksum offload is enabled: Offload parameters for eth0: rx-checksumming: on tx-checksumming: on scatter-gather: on tcp segmentation offload: on udp fragmentation offload: off generic segmentation offload: off The following is the output of powertop when the network is idle: Wakeups-from-idle per second : 61.9 interval: 10.0s no ACPI power usage estimate available Top causes for wakeups: 90.9% (101.3) <interrupt> : eth0 4.5% ( 5.0) iftop : schedule_timeout (process_timeout) 1.8% ( 2.0) <kernel core> : clocksource_register (clocksource_watchdog) 0.9% ( 1.0) dhcdbd : schedule_timeout (process_timeout) 0.5% ( 0.6) <kernel core> : neigh_table_init_no_netlink (neigh_periodic_timer) And when the maximum throughput of about 25MB/s is reached: Wakeups-from-idle per second : 11175.5 interval: 10.0s no ACPI power usage estimate available Top causes for wakeups: 99.9% (22097.4) <interrupt> : eth0 0.0% ( 5.0) iftop : schedule_timeout (process_timeout) 0.0% ( 2.0) <kernel core> : clocksource_register (clocksource_watchdog) 0.0% ( 1.0) dhcdbd : schedule_timeout (process_timeout) 0.0% ( 0.6) <kernel core> : neigh_table_init_no_netlink (neigh_periodic_timer) Notice the 20000 interrupts per second. Could this be the cause for the high CPU usage and low throughput? If so, how can I improve the situation? The other computers in the network can usually transfer at 50+MB/s without problems. And a minor question: How can I find out what is the driver in use for eth0?

  • CD Drive not discovered

    - by user1009073
    I have a self built computer. it uses a P6T Deluxe motherboard, which has both SATA and IDE ports. This was built several years ago, and had an IDE CD/DVD drive. This drive started going bad (would not burn CDs correctly), so I decided to replace it. I had difficultly finding an IDE DVD drive, so I bought a SATA DVD drive. I opened the comnputer, took out the old DVD drive. I left the IDE cable in place, connected to the motherboard, but it is not connected to any drives. I hooked up the new DVD drive, both power and with a SATA data cable (SATA port 3 if I recall). (Sony Optiarc 24x , Newegg URL: http://www.newegg.com/Product/Product.aspx?Item=N82E16827118067 ) When I power on my computer, the drive does NOT show up in Explorer. I can hit the DVD eject button, and the drive will open up, so I know it at least is getting power. I thought, maybe something in the BIOS. When I go to BIOS, boot devices, it shows (1) floppy, (2) my hard drive (3) ATAPI CD Drive. The only other possible BIOS option I could find was uder 'Storage Configuration'. Configure Storage as: My setting is RAID, since I am using two drives in a RAID configuration. Other options were IDE and ACHI. Other than trying to find an IDE DVD drive, is there anything else I can try? The drive does not show up at all in Windows Explorer. I did put in a CD thinking that might help, but nothing happened. Thanks, GS

  • ASUS laptop doesn't charge/use the battery after reinstalling Windows 7

    - by Stan
    I've done a clean install of Windows 7 x64 on an ASUS X501A laptop. The battery is detected and shows in the system tray as "plugged in, charging". However the charge level stays at 76% and if the AC cord is plugged out the laptop turns off. The laptop does not turn on without being plugged in either. Everything worked perfectly prior to reinstall. I've tried: Downloading and installing all the ASUS drivers, including the ATK ACPI driver Checking the BIOS - there do not seem to be any battery-related settings Flashing the BIOS to the latest version Uninstalling Microsoft ACPI-Compliant Control Method Battery in device manager as suggested on the internet Full power discharge/ATX reset as suggested by ASUS support: remove mains power charger, remove battery, press and hold power button for 10 seconds, reconnect battery and mains and turn on I have a feeling all this may have something to do with the EFI BIOS that comes on the laptop. During the reinstall I had to delete all partitions and start anew, because the Windows installer complained about the improper order of GPT partitions. The EFI System Partition was recreated by the installer, and I am guessing that it may be missing the particular ACPI driver needed to make the battery work. I've tried researching this, but could not come up with any useful info. I am hoping someone here may know a bit more about this and maybe help me understand what's going on and how to fix it. Barring that, I'll have to re-image the drive off an identical ASUS laptop with stock install and hope it fixes things.
