  • How to test which button is stuck

    - by Macha
    My laptop's keyboard is prone to buttons sticking. The fix is to just press the same button again. Now when it is the letter/number keys are stuck, it's just a matter of putting the cursor in a text field, and seeing what characters appear. However, when it is one of the modifier keys, or tab, or enter or a few other buttons, it gets harder to tell which key is to blame. Trying to type can result in all sort of shortcuts being triggered. Is there anyway to test what input is being recieved? Also, I'm guessing this is a hardware issue, but if anyone knows of any possible causes/solutions it'd be appreciated. It's a Dell Studio 17, and the problem occurs under Windows and Linux.

  • Windows 7 not detecting external hard drive but Ubuntu is detecting. Why?

    - by unlimit
    I have a 500 GB Toshiba external hard drive. Since yesterday Windows 7 stopped detecting it, however I do see it listed on the "Safely remove hardware and eject media" icon on the taskbar. Then I tried the same external hard drive on my Ubuntu and it detected it just fine. Ubuntu and Windows 7 are on the same laptop. I have dual boot. Can someone tell me why is it happening? Am I missing a driver in Windows 7? Additional info: This drive has worked perfectly fine in the past. I did not format this drive ever. It just stopped working yesterday in windows.

  • My laptop (Acer Aspire) doesn't want to start.

    - by Adi87
    I have an Acer Aspire 5520G and recently I had a big problem with it. A couple of days ago I was watching a video on the internet and my laptop froze. I had to shut it down after waiting a couple of minutes and when I wanted to restart it, it acted normally for 2 seconds then it restarts automatically over and over again. I can only shut it down by unplugging it. Nothing appears on screen. I think that it is a hardware problem. If you need further information please leave comment.

  • Server not repsonding after Ubuntu upgrade

    - by aaa
    I have a server that was running Ubuntu 8.04. I upgraded Ubuntu via the command-line and got no warning messages. After it was done the server restarted but now I am unable to SSH back in. My site is also not resolving. My guess is I overwrote something important. What are some trouble-shooting steps I can take? I am able to execute commands through my VPS provider's admin interface. I'm not sure what version it upgraded me to honestly.

  • Chipset fan on the frtiz - compressed air hasn't fixed anything - is there anything I can do?

    - by Anthony
    Yesterday, my computer started to make an annoying whining noise. Knowing that this is likely a fan issue, I opened the case and proceeded to determine which fan was causing the issue. I got some compressed air and tried cleaning out the dust around it (and the rest of the computer while I was at it). This hasn't seemed to fix the issue. Now, if it were just any fan, I would probably just replace the fan - they're relatively cheap after all. However, this is a special fan. Aside: For what its worth, I feel bad that the graphics card blocks part of the fan, but it is the only slot the graphics card fits, so I had no choice. After pulling out my motherboard user guide, it looks like this is a fan placed directly on top of the chipset. To be perfectly honest, I have no clue what the purpose of the chipset is - but it sounds important. After some quick research, I see that it is responsible for providing the bridge between my CPU, RAM and graphics, among other things. Just a quick search at Newegg tells me that chipset fans can be purchased at pretty reasonable prices (< 20 dollars). Is it practical to replace this fan? It is an old computer as computers go and I wouldn't be terribly upset to upgrade the motherboard and processor, so perhaps this is a sign.

  • How to transfer Windows Vista disk image to new machine

    - by Mike Hobbs
    I'm trying to upgrade a user's machine to some better hardware. I know of Easy Transfer, but I'd rather not have to reinstall all the programs that are already present. (Some of which are no longer available, anyway). Instead, I'm trying to transfer the entire disk image from one machine to the other, but I ran into issues. If I copy the partition image over to the new machine using Clonezilla, I get errors on boot saying that I need to insert the Vista install disk and run repair. I do that, but it then says that it is unable to repair whatever it is that's broken. Next, I tried to sysprep the old machine before creating the image, but sysprep fails saying that it encountered some sort of system error. Should it be possible to sysprep any arbitrary machine, or does it only work on a relatively clean install? Could it be a missing driver that is tripping me up? The new machine is a fairly stock desktop that shouldn't need any special drivers beyond what's already present in standard Vista. Are there any foolproof methods for doing this sort of thing?

  • NVidia Graphic Card troubleshooting

    - by Berry Langerak
    My dad has a HP pavilion laptop, which is over 6 years old. It contains an onboard graphic card, a NVidia GeForce 8400M GS. Since a week or two, he's getting BSOD in Windows Vista. Also, the screen was acting up; strange lines and figures keep creeping up, but only once in a while -- not always. Thinking that it might be the drivers he had recently upgraded, I decided to downgrade the driver, with no luck at all. I then continued to deinstall the driver, and reinstalling the current stable version, but alas, to no prevail. Windows kept crashing during the course of the last two weeks, and thinking it might be Windows breaking up, I decided to upgrade his Vista installation to Windows 7, as I've been hearing good things about it. Alas, even that didn't help, and it seems the strange lines and figures keep popping up. I've opened the laptop itself, thinking it might simply be overheating because of clogging in the vents, but that's not the case, it's clean as a whistle. Now for the actual question; does anyone have a decent flowchart on how to troubleshoot such issues? It might well be the videocard itself, as the strange lines and figures sometimes even appear during BIOS and POST, but I'm not sure.

  • Laptop won't boot with both memory slots used

    - by Johnny W
    I'm currently trying to upgrade my old Sony Vaio VGN-SZ1HP/B to 2GB of RAM. It already had 1GB of Crucial RAM in one of its slots, and one empty. I checked on Crucial.com and it confirms that each bank can hold 1GB of PC2-5300. The 1GB stick already installed was this, but Crucial's page recommended this... The two are identical from what I can make out, so I just ordered another one of the former. Unfortunately the machine refuses to even POST with both sticks installed. If I remove the old RAM from Slot 1 and replace it with the new RAM it runs fine. If I leave Slot 1 empty and put RAM (either stick) in Slot 2, it won't POST. Basically it seems that Slot 2 just isn't working properly. Does anyone have any ideas on how to solve this problem? Or maybe have any experience with this sort of thing with Sony Vaios? Thanks for any help!

  • Windows 7 fails to install

    - by Brian Ortiz
    I'm upgrading from Vista SP1 (which was actually upgraded from XP over a year ago) to Windows 7 RTM (64-bit Ultimate to 64-bit Ultimate). After 4 hours or so, the install fails with the message "This version of Windows could not be installed, Your previous version of Windows has been restored, and you can continue to use it." This error is back at my Vista desktop, there's no error that I could see during install, I just a message indicating that it was reverting everything. I tracked down the error logs and here's the log at I uploaded the error log (from C:\$WINDOWS.~BT\Sources\Panther) and uploaded onto Pastebin. Here is an excerpt: 2009-08-09 02:54:57, Error Number of Enumerated Devices = 21[gle=0x00000103] 2009-08-09 02:54:58, Error Failed to find driver file path. Error=00000002x 2009-08-09 02:54:58, Error Failed to find driver file path. Error=00000002x 2009-08-09 02:54:58, Error Failed to find driver file path. Error=00000002x[gle=0x80092004] 2009-08-09 02:54:58, Error Failed to find driver file path. Error=00000002x[gle=0x80092004] It was suggested that I upgrade to SP2 before upgrading to Vista, but this made no difference. I since uninstalled SP2 since it was creating some problems with a piece of hardware. I know a fresh install is best, but I'm hoping to avoid that because I'd need a new hard drive. Per Reuben's instruction, I found the install's dump and uploaded it here. (266 KB)

  • Trouble cloning a Macbook Pro hard drive

    - by Mirko Froehlich
    I am trying to upgrade the 250GB hard drive in my MacBook Pro (early 2008 model) to a 750GB drive. I have connected the new drive via an external USB enclosure. The drive is recognized fine, I can format it, etc. However, every time I try to clone the drive, I am getting Input/Output errors. Before the clone operation, I have verified both the internal and the external drive using Disk Utility, and they both check out fine. After the clone operation, the external drive shows multiple "Invalid node structure" errors: I have tried two approaches for cloning the drive: Using Disk Utility, by starting from the OSX install DVD Using Carbon Copy Cloner The outcome is the same in both cases. The Carbon Copy Cloner logs show a handful of the following types of errors: rsync: mkstemp "<... an external filename ...>" failed: Input/output error (5) rsync: stat "<... an external filename ...>" failed: Input/output error (5) The actual files affected seem to be different across different runs of the application. Before the last run, I used Disk Utility to (once more) reformat the external drive and explicitly overwrite it with zeros, but this made no difference. I also tried running a surface scan in Tech Tool Pro overnight. It got about 2/3 of the way through before I had to disconnect the drive (had to take my MacBook Pro to work), but so far it didn't report any bad blocks. Assuming it scans the drive in the same order in which blocks would be allocated during actual use, it seems like if bad blocks were to blame for the clone failures, they should have been found already (given that the source drive is only 250GB). As a last attempt, I may try SuperDuper as well, although my understanding is that it uses the same underlying rsync approach as Carbon Copy Cloner, so it's unlikely to perform any better. Are there any other things I should try before I send the drive in for a replacement? Could these problems be caused by my internal drive, even though it works fine and checks out fine in Disk Utility?

  • PC can't detect second RAM installed

    - by kulwinder
    I have PC with 512 MB RAM installed (motherboard manufacture MICRO STAR, chipset P4M800), pc was running very slow so I decided to upgrade the ram. I installed CPU-Z and check the ram installed on the machine, also had a look at the stick installed. 512 MB PC 3200 400 MHz DDR but my mother supports 200 MHz and it was working ok. So I bought 2GB which I checked on manual that it support upto 2 GB Ram. So I installed 2GB PC 3200 400 MHz same as the old one, I plugged in both eventhough motherboard only support upto 2 GB but system spec only shows 512 (deducts 64 MB shared vga memory) I checked on CPU-Z, it detects both, slot 1 512 MB, slot 2 2048 MB, comparing screen for both slots, both the same, volt 2.5, frequency 166 MHz and 200MHz, only difference on those is 2gb ram shows under timings table 133MHz 166 MHz and 200MHz but 512 MB shows only 166MHz and 200MHz. I checked on Google and can't seems to figure out whats wrong with it. If I only plug in 2GB. Pc doesn't boot up like ram not working.With only 512 MB plugged in seems ok. Please help.

  • Computer turns itself on after any off mode

    - by Patrick
    Whenever I shut down my computer, or put it in sleep/hybernate, it turns on after two seconds. It doesn't post, it just powers on and then idles. To actually turn it off, I switch off the psu. The problem is now, whenever I switch the psu on and try to boot, it doesn't always turn on. It takes a good amount of flicking the psu switch on and off before the motherboard lights up. So far I've determined the things its not: its not caused by the mouse or network waking up the computer. I've been able to go into hybernate for the past year. And all "wake on X" settings in the bios are diabled. its not a scheduled task waking up the computer at a given hour, it occurs every single time its not due to an upgrade or new installation, since I haven't done either in a very long time I'm sure its a hardware issue. So I'd like to know, is my psu dead, or the motherboard? The psu is an Antec Earthwatts 600w, the motherboard is an Asus P5Q-E, both one year old.

  • (manually configured) kernel update leaves wireless in a mess

    - by Mala
    I recently upgraded my kernel from 2.6.31-gentoo-r6 to 2.6.32-gentoo-r7. In both cases, I configured everything manually. However, since the upgrade, my wireless card appears to be on the fritz. It will connect to networks just fine, and remain connected, but can only access the internet (and other hosts on the network) for about 3 seconds after connecting. Reconnecting to the network appears to fix the problem... for another 3 seconds or so. The problem is "solved" by booting into the older kernel. The relevant lspci entry is 02:00.0 Network controller: Intel Corporation PRO/Wireless 5300 AGN [Shiloh] Network Connection I'm pretty sure I have the correct drivers enabled in the kernel Device Drivers ---> Network device support ---> Wireless LAN (IEEE 802.11) ---> <*> Intel Wireless Wifi [*] Enable LED support in iwlagn and iwl3945 drivers [*] Enable Spectrum Measurement in iwlagn driver [*] Enable full debugging output in iwlagn and iwl3945 drivers <*> Intel Wireless WiFi Next Gen AGN (iwlagn) [*] Intel Wireless WiFi 4965AGN [*] Intel Wireless WiFi 5000AGN; Intel WiFi Link 1000, 6000, and 6050 Series I tried with the other intel drivers enabled as well (iwl3945) and no difference. Is there something stupid I'm missing? Is there something I have to recompile after upgrading the kernel (a la nvidia)? Thanks Mala

  • Any dangers in using DDR memory with a higher frequency than the FSB?

    - by raw_noob
    I'm looking to upgrade memory in an older motherboard. The processor is an AMD Sempron 2500+ with a maximum speed of 333/166MHz. The motherboard is an MSI MS-7061 (KV3M-V), which accepts up to 2Gb of DDR memory maximum PC2700 in 2 slots and has a maximum FSB of 333MHz. The board does not have dual-channel support. Existing memory includes a stick of 512Mb PC3200, which seems to be running OK (presumably at PC2700) but is rated 200MHz, which is below the FSB speed. The other stick is 256Mb PC2100/133MHz, again below the FSB speed. (All figures from CPU-Z.) I have a chance to acquire a single used stick of PC3200/400MHz memory very cheaply. Crucial's system scanner seems to suggest that this will be OK with my system, but other sites have suggested that running memory with a higher frequency than the FSB can cause instability. Is this true? Would I be better waiting until I can buy the correct PC2700/333MHz stick? I'm assuming that the mixed memory I have at present is running as 768Mb at 133MHz. Is this a reasonable assumption? If so, would you expect the performance differences between 768Mb/133MHz and 1Gb/333MHz to be very noticeable? If I install the new 1Gb/400 or 333MHz stick in slot 1, am I right in thinking that adding back the existing 512Mb/200MHz stick in slot 2 would pull the whole 1.5Gb system memory speed down to 200MHz? If so, which would be better - 1.5Gb/200MHz, or the single 1Gb stick at the full 333MHz that the FSB permits? Is more headroom more important than extra speed? Any help - or even opinions - gratefully received. I can't find reliable information, and I can't afford to make expensive mistakes.

  • Gateway laptop module bay light repeating 12 flashes - what error is that?

    - by Simurr
    I have a Gateway M465-E laptop currently running fine with a T2300E Core Duo installed. I wanted to upgrade it to a Core 2 Duo. My brother has the same model laptop and that took a Core 2 Duo (T7200) just fine. Picked up a T7200 on ebay and installed it. Normally when booting all the indicator lights flash once and the fan spins up before the machine actually starts to POST. With the T7200 installed all the lights flash and the fan spins up, but the module bay activity light flashes 12 times repeatedly. I'm assuming this is an error code, but can find no information about it. There are no beep codes. I've removed the ram, HD, Bay module and no change. Switched back to the T2300E and everything works fine. Anyone know what that error code is? The motherboard was actually manufactured by Foxconn if that helps. Update 1 Returned the CPU as defective. I tested it in 3 M465-E's and all of them did exactly the same thing. I still have no idea what the error code is. I'd still like to know for future reference. Perhaps I should try removing the CPU from one of them and see what happens.

  • Windows 8 Windows Store (Metro/ModernUI) applications not working (just show 'busy' animation or white screen)

    - by davidm_uk
    I have a Dell XPS 15 which shipped with Windows 7 x64, which I recently upgraded to Windows 8. The process went surprisingly smoothly (given that this was an upgrade, not a complete re-install), and the system generally seems very stable. However, today I noticed that several of the Windows Store apps don't work: they all behave in the same way, launching but then showing a spinning 'wait' animation indefinitely. This is affecting the standard Microsoft Mail, Store, Weather, News, Travel, Finance, Sport, Games and Music apps. The Bing app just shows a Bing logo on a coloured background (but no wait animation). The Calendar, Photos and SkyDrive apps open but then show a white screen. The Maps and Camera apps work without problems. The live tiles on the Start screen are updating correctly, for example the Mail app's tile shows a summary of new mail despite the Mail app's problems. All of these applications were working correctly a few days ago. I'm sure I've used several without problems since the last Windows update occurred on 7th November. Any suggestions on what might have happened and/or how to fix it would be very welcome. I don't need these Windows Store applications, but the fact that they're not working is irritating me.

  • How can I upgrade to Lubuntu 14.04.1 withot a PAE kernel?

    - by Richard
    On my Dell Latitude D800 laptop, which has an old Pentium M without PAE support, I was able to successfully install Lubuntu 14.04 from the CD. When I try to upgrade, I get the error: PAE not enabled Your system uses a CPU that does not have PAE enabled. Ubuntu only supports non-PAE systems up to Ubuntu 12.04. To upgrade to a later version of Ubuntu, you must enable PAE (if this is possible) see: http://help.ubuntu.com/community/EnablingPAE I have seen the Communit Wiki page for PAE. The suggestion is to add forcepae to the command line options. When I do this, I get the same message. Moreover, dmesg does not indicate PAE was ever enabled. Is there anything else I can ry to get Lubuntu to upgrade correctly?

  • Upgrade guide for Kohana 3.0.9 (from 3.0.8)

    - by Darryl Hein
    Is there an upgrade guide for Kohana 3.0.9 from 3.0.8. I'm looking for something like what jQuery provides when they release a new version. It allows for a quick scan of the changes to notice if there's anything I could use or would change how I've done things. The resolved issues are part of this, but I'm looking for something more high level. The issues require reading everything in each issue and it's often hard to understand what's actually changed.
