• Can't install Windows 7 on Acer Aspire M1100

  - by r0ca

  When I install Windows 7, everything goes smooth but as soon as it's done and Windows needs to reboot for the last time before getting the desktop, the computer stucks to Verify DMI Pool Data............. and then, nothing. I change the CMOS battery, I tried so many setup in BIOS, even load default settings... Nothing worked. The HDD light is not flickering anymore, no HDD activity. CTRL-ALT-DEL doesn't work. It's just impossible to load Windows 7. I tried Windows XP and this works fine. I also tried the Acer (Futureshop) recovery CD and I get an Hexademical error message stating the install cannot continue. Is there a BIOS flash apps somewhere or a fix I can apply to have Windows 7 Ultimate installed on my computer. Any takers?

• MacBook Pro - 7200 vs 5400 rpm drives - Heat and Noise

  - by webworm

  I am looking at a new 15" MacBook Pro for development purposes. I am planning to run a Virtual Machine for about 50% of my work (Windows 7 x64, IIS, SQL Server, and VS 2010). The upgrade from a 5400 rpm drive to a 7200 rpm is only $45. From what I understand the faster rotational speed of the 7200 rpm drive will help virtual machine performance. However, I am concerned that additional heat and fan noise might be an issue. I will be running mostly on A/C power so decreased battery life is not a major concern for me. Since I would be running with a Core i7 processor which gives off a fair amount of heat already I was wondering if it might be best to stay at 5400 rpm for the hard drive. What do you all think? Thanks!

• Master Reset iPhone - How?

  - by sagar

  Actually - I had a problem with my iPhone. My iphone battery was down & it was switched off. I plugged in it for charging, but after some time - iPhone had a complete white screen. I don't know what actually had happened. Every thing was working perfectly. means suppose I press lock ( button on top-right side ) it sounds that iphone is locked. when I pressed home button & slide on bottom of the screen - it sounds that iphone is unlocked - but the only problem was - screen remains "white" only. someone told me - it needs master reset. I went to an engineer & he just master reset to iPhone. I am wondering how an iPhone can be master reset ? can you guide me about it ? Thanks in advance for sharing your knowledge. Sagar

• Best software for taking math notes at lectures

  - by data_jepp

  Let me first just say that I know about La-Tex, and that doesn't fast enough. I use it for papers, but for "real-time" note taking it's just to heavy. I'm talking two math classes this semester. Linear algebra and discrete math, I just got a laptop with 10 hour battery life which makes me want to take notes on it!!! Openoffice with formula thingy is what I use now. Now I have to pay attention lol. Thanks.

• New build won't POST, no video, no beeps

  - by Nate Koppenhaver

  Specs: Motherboard: MSI 760GM-P23 FX Integrated graphics (on MoBo) CPU: AMD Athlon II x4 640 RAM: GeIL Pristine 4GB DDR3 Case/PSU: TOPOWER TP-4107BB-400 Is not POSTing, no video output, no beeps. When RAM is removed, 3 beeps. I have tried removing and replacing the CPU and all the power cables with no change. Resetting the BIOS (by removing and replacing the battery) did nothing as well. Is there something I'm forgetting (1st time building from components), or could one of the components be bad? EDIT: New development: with CPU and RAM installed correctly, it will turn on lights and fans (still no POST) and after running for a minute or so it will turn off and the PSU will make a buzzing noise that ceases only when unplugged.

• Assistance in setting up new APC Smart-UPS RT on a new VMware enviroment

  - by user38085

  I'm new to the realm of setting up a APC Smart-UPS RT 8000VA UPS with a management network card (AP9618). The project calls for the upgrade of the firmware for the network card to the newest and greatest. It also calls for the Powerchute Business Software to be installed with notifications setup per email for temperature, shutdown, and battery low. I know I'll have to use the serial cable to flash the firmware and install the software on one server 2003 box. Also on that server I'll have to install the software and setup the GUI (IP address) interface. Whats confusing the most is the whole process, and steps to use without taking down the network, which would be very bad. In flashing the firmware does it take down the UPS? Do i have to run BOOTP commands to setup the network card? Also no agents will be used on any of the VWware OS's and no SNMP trap will be used.

• Supplementary Developer Laptop

  - by David Smith

  I'm looking to buy a laptop with the following specs for a developer. The goal will be to have a development machine supplementing the devs desktop. During work hours the dev will be on a beefy desktop. For working while on the go: trains, client sites, code camps, it would be nice to have a machine which can run Visual Studio 2008 without needing to remote desktop into their primary machine. What do you think is the lowest cost laptop meeting this need? Here are the specs I have in mind: SSD drive 64GB-doesn't need to be huge, most data is stored on servers. Will need to fit Windows 7, IIS, SQL Server, and Visual Studio 2010. RAM-3GB processor =Pentium Core 2 duo Screen size = 14 inches. OS doesn't matter. It will be paved with Windows 7 Ultimate optical drive omitted would be a plus. weight and battery life aren't so important because the machine will be plugged in almost all the time.

• Windows 7 power management in Boot Camp mode

  - by qntmfred

  I have a Macbook Pro with Windows 7 installed in Boot Camp. I have serious problems with the power management and not sure why. I have the default Balanced power plan selected. Many times when I close the laptop and leave it for more than just a few minutes, when I open it back up, it does not awake immediately. I end up having to press the power button to get it to wake up. Sometimes this causes it to wake up in Windows mode, sometimes it reboots completely, sometimes the battery has been drained and Windows has to restart. Is this a common problem? Can I fix it?

• which factors determines the speed of a processor? [closed]

  - by Deb

  I think that clock rate of processor determines the speed of core, in my case it is 1.86GHz. But If I am not wrong, it also determines that how much energy it will consume. If you have more frequency then more power it will consume. I choose Power Saver scheme to increase my battery life, however it reduces my core speed to half of the actual speed. I understand this happens because of SpeedStep, but I don't see any slowdown of my computer. So my problem is why we have such high frequency cores as it uses too much power. We can use low frequency cores. Actually I get confused between the two terms Speed of the processor and its frequency. So how much important is the frequency of core in case of any processor.

• About HDD enclosure

  - by kmitnick

  hey guys, how r u doin? I have this 3.5" IDE enclosure, and it works great, I mean I love the idea of enclosures ( not the power feeding thing :), btw can't I just insert a chargable battery to feed the power when I am unable to find an electricity block), anyway my question is, when I finish the usage of the enclosure I safely remove it when using Windows or umount when working with Linux, and after that I got confused whether to turn it off or no? when I turn it off, the HDD suddenly stop spinning as if power failure not as when it was an internal and normally shuted down the pc. So is it ok to turn it off the way I've just said??? regards, ~Abed

• Im getting the "Console Window Host has stopped working" popup in a few places.

  - by m1sk

  Im running Windows 7 on a 17 inch Macbook Pro, late 2011. Last Saturday I opened my laptop(It was either asleep or shutdown before hand) and suddenly had a whole bunch of problem. First off I got a few of pop-errors, my macbook was out of battery. I also had problems with my trackpad(no scrolling or right-click), which I fixed by reinstalling bootcamp. Now a days when ever I run cmd I get the popup Console Window Host has stopped working If I chose the Close the program I get another popup The application was unable to start correctly (0xc0000142) Click OK to close the application. This doesnt happen just with cmd if un/install a program I get similar popups(first one). And in some other case like in visual studio when i was working on class work.

• Intel 520 SSD drives not working with lsi controller on VMware esxi 5

  - by Michael

  We have a problem with our LSI 9266 controller. LSI have vmware drivers which normally show the health status of connected drives, raid controller, battery etc from within the vSphere Client. This driver also allows connectivity from the LSI MSM utility from a windows workstation. The problem is as soon as I connect my intel 520 SSD drives the health status in the vsphere client disappears, also we lose connectivity via the LSI MSM utlity. Any other drives we test are fine, 1TB SAS drives, other SSD drives etc are all OK. The Intel drives are on the compatability list and are supported by LSI but dont work with the VMware driver. If I install a windows OS on the physical server we have no problems. I have logged a ticket with LSI but they havent been very helpful. I am trying to find other people that may have had the same issue and maybe even a fix

• ZFS SAS/SATA controller recommendations

  - by ewwhite

  I've been working with OpenSolaris and ZFS for 6 months, primarily on a Sun Fire x4540 and standard Dell and HP hardware. One downside to standard Perc and HP Smart Array controllers is that they do not have a true "passthrough" JBOD mode to present individual disks to ZFS. One can configure multiple RAID 0 arrays and get them working in ZFS, but it impacts hotswap capabilities (thus requiring a reboot upon disk failure/replacement). I'm curious as to what SAS/SATA controllers are recommended for home-brewed ZFS storage solutions. In addition, what effect does battery-backed write cache (BBWC) have in ZFS storage?

• Why no "da-doomp" (disconnect notification sound) sometimes when unplugging wireless mouse receiver?

  - by DanH

  Sometimes (maybe one case in 3), when I unplug the wireless mouse receiver on my Sony VGN-CS215J laptop, there is no "da-doomp" sound, even after a minute or two. And if I plug the receiver back in there is no corresponding "du-dump" sound and the mouse is still (immediately) "live". This can happen when the activity light is out and there's nothing obviously going on -- it's not simply that the box is too busy. Other times one gets the expected behavior (and usually I get the correct behavior if I plug the receiver back in a few seconds and then unplug it after a "failure"). The reason this is significant is that if I get no "da-doomp" then the laptop will not sleep properly -- it will go to sleep initially, but then reawaken a few minutes later inside my laptop case and proceed to run the battery down (and no doubt overheat the unit). Any ideas?

• Windows 7 Standy/Hibernate Freeze/Lockup

  - by Kyle

  I'm running Windows 7 Ultimate on a MSI U100 Netbook which often experiences a lockup or freeze whilst hibernating or shutting down. I have a friend with an Asus netbook running Windows 7 who has experienced the same issue. This happens to me perhaps 1-2 times a week, and is frustrating as hell because it will just sit there running flat out (the fan goes to max after a while) until the battery dies if I don't notice it first. Just wondering if anyone has had any similar issues or might be able to point me in the right direction. The freeze occurs when the screen has faded to black. The HDD light flickers for a few moments then just sticks on solid. I haven't been able to isolate any apps which may be causing this either. It will be fine one standby, and lock up the next with no new apps open. Any thoughts greatly appreciated. Cheers, Kyle

• HFS for Windows by Paragon BSOD

  - by texmex5

  Installed HFS for Windows 7 yesterday. Did a reboot. Copied some files from my internal drive to external hfs drive. Did another reboot and rebooted to Mac. Mac worked fine. Then yesterday the battery went dead on my mac and the computer switched off. This morning tried to boot into windows but got a BSOD as soon as I moved my mouse in the login screen. BSOD refeers to an error with service HFSPLUS.SYS Now when I try to boot into mac (pressing alt while restarding) the mac drive isn's shown and I can only boot into Windows 7 Safe Mode. Cannot uninstall HFS for Windows the uninstaller in control panel says: "THE WINDOWS INSTALLER SERVICE COULD NOT BE ACCESSED. THIS CAN OCCUR WHEN WINDOWS INSTALLER IS NOT CORRECTLY INSTALLED". SETUP: Intel Core 2 Duo, P8600 @ 2.40GHZ, 4GB RAM, WINDOWS 7 ULTIMATE 32 BIT

• What happens to modern-ui apps when they aren't in the foreground?

  - by Mark Allen

  If I start a modern-ui app and then switch to a different app or a normal program running on the desktop, what happens to the first app? I've heard something about the first app being suspended, but realized that I don't really know that for certain. I mean, could you write a SETI@Home (BOINC) app if you wanted to, or will apps that aren't in the foreground always be suspended? Can you change that? I could see changing that based on available resources, running from AC vs. battery, etc. This morning I heard about an iPad being recovered thanks to the "Find my iPad" app, and was wondering whether you could write such a thing as a modern-ui app and have it work without being the running foreground app. (I'm aware that you'd just write a Windows service or similar, that's not what I'm asking about.)

• Apple MagicMouse randomly loses connection

  - by Yuval

  My Magic Mouse periodically randomly loses connection to my macbook, sitting approximately a foot and a half away from it. There are no software updates available for Snow Leopard (10.6.3). I have a bluetooth keyboard (that sits a little closer to the macbook, though I'm not sure this is the issue) that rarely suffers from this problem. Google results mostly suggest to update the software but I have the most updated version of it already. Does anybody have any idea what could be causing the issue? Is this simply a defective mouse? Additional info: I tried replacing the batteries with new ones, making sure they are sitting tightly in their position with no change in behavior (still disconnects periodically). Also, this doesn't seem to be a problem that the mouse is turning itself off to save battery - it does not reconnect when I move or click it. If I wait long enough (a couple of minutes) it reconnects on its own. Otherwise I have to go to the bluetooth menu with my macbook touchpad and choose "yuval's mouse - Connect"

• Acer aspire 5520 power light blinks no boot

  - by Shawn Mclean

  My laptop was working fine last night, I hibernated it and went to sleep. Got up, pressed the power button. The power light comes on for 4 seconds and the hdd light blinked a few times, then it turned off for a second then repeats the process. The only way to stop this process/power down is to remove the AC and take out the battery. It does not even reach a boot screen, nothing shows up on the screen, fan does not start. People on this forum has the same problem but they suggest to put the laptop in a oven and heat it (reflow). What could be the problem? Is there another solution other than a reflow? I dont feel like putting my motherboard in the oven.

• What could be causing Windows to randomnly reset the system time to a random time?

  - by Jonathan Dumaine

  My Windows 7 machine infuriates me. It cannot hold a date. At one point it all worked fine, but now it will decide that it needs to change the system time to a random time and date either in the future or past. There seems to be no correlation or set interval of when it happens. To remedy it I have: Correctly set the time in bios. Replaced the motherboard battery with a new CR2032 (even checked it with a multimeter). Tried disabling automatic internet synchronizing via "Date and Time" dialog. Stopped, restarted, left disabled the Windows Time service. Yet with all of these actions, the time will continue to change. Any ideas?

• Serial number not found, copy of Windows not genuine

  - by sara

  I have an HP-G71-340US notebook that I purchased 11/29/09. When I power it up, a black screen comes on that shows "serial number not found" and it also says that my copy of Windows 7 Home Basic is not genuine – but my computer came with Windows 7 Home Premium. In BIOS, my serial number is not shown either and I did pull out the little battery to reset it which allowed me to bypass the suddenly new locked BIOS that needed a password to enter. I'm sure this is a masterpiece created by my 6 or 9 yr old child while trying to play on my laptop. Can I fix these two problems?

• Wake network adapter from deep sleep mode

  - by BeatMe

  I recently buyed a new Mainboard (Asrock ALiveXFire) and got some trouble with the network adapter. After switching my Windows 7 x64 in energey saving mode and returning from it, my network adapter couldn't be found. After some googling I found out, that apparently my network adapter has been put in a deep sleep mode and didn't reactivate. Their solution was to switch the PC off, take out the RAM and the CMOS battery for some time. After that, the adapter should be powered on again, but that didn't happen for me. I waited several hours before turning my PC on again, but that didn't help. Formatting and reinstalling didn't help either. The network adapter is not found in the hardware manager and reinstalling the drivers didn't help. I have the newest BIOS installed on the mainboard. I literally don't know what to try next. I'm thinking of returning my board, but I would like to avoid the hassle.

• Program shortcuts disappearing in Windows Mobile 2003, any way to get them back?

  - by Carlisle White

  I have a WM2003 device with some programs installed on it and a full backup created and saved to a SD card. If the device runs out of charge for some time (or the battery removed) everything is reseted back to defaults, so the custom programs and configs are gone. When this happens I used to restore the full backup to put everything back to normal again. But I've recently installed TomTom Navigator 7 and for some reason, its shortcut in the "Programs" section is not saved when creating a full backup (with the eBackup app provided) and the installation doesn't create a shortcut in the main screen (as version 6 used to do). Is there any way to make this shortcut persistent? Is there any way to create custom shortcuts in the programs section or in the main screen (preferably)? Thank you very much for your help, anything is welcomed.
