power issues

Win 7 automatically shuts down on me after about 8 hours. No matter what I'm doing, it just powers down and I lose whatever was on the screen. I have a Dell laptop and use it on electricity only. It also sits on a unit with two cooling fans. Have never used it on battery. I checked my...

Recently I bought a Windows 7 pc. After years with XP and Vista - and NAS'es Qnap TS-109 and Maxtor Shared Storage Plus - I am suddenly very unsatisfied:( Once every day (or moere) my pc loses contact with the NAS'es. Only way to get connected again is to cut power since restart is not possible...

Ok, so my computer information is in my profile so there is no need for me to post that. I have had EVERY part replaced now, so it is not a hardware issue. The only time i get this is when i am using a 3D application (e.g. Borderlands, Need for Speed: SHIFT, and all other games). This is the...

I have Windows 7 (64 bit) installed. I mistakenly shut my computer down using the sleep button a week ago. When I press the start button on my computer, I can see/here the computer starting. I get several lights on steady on my keyboard but the mouse and the monitor never seem to work. I have...

Today, after a regular update of the OS (which is a Windows 7 HP 64-bit) my mouse stopped working. Unplugged it, pug it back and got an error message saying that the driver was not installed correctly because it could not be identified (I have been using Windows 7 for a month and nothinh...

I recently upgraded from Vista to Windows 7 (64 bit) on my Acer 4810T-8480. One problem I've been noticing frequently is that when I tell the computer to sleep or even just close the laptop lid, the screen will go black, but the power light will stay on, as opposed to blinking orange as it used...

ok so i have a big problem. i've been running 7 for some time now, all has been good with no problems what so ever, until last night. my mouse and keyboard stopped functioning, i thought maybe it would pass if i restarted. well that was a big no when i got to the login screen and couldn't type...

hi all my computer keeps freezing. The hard drive led stays fully lit and the power light goes off but the fan still spins. I have to hold the power button in to reboot and then it asks if i want to go into safe mode. I have had win 7 for a good 2 months and ive only noticed it the past week ...

I really hope someone can help. I installed windows 7 as an upgrade - everything seemed to be working ok for a few days at least. Went to bed one night, got up next morning and no computer functionality although the computer power light was on. I couldn't even power the computer down using the...

I successfully installed Windows 7 on my computer this week, but the computer sometimes loses contact with my Western Digital Mirror 2 terabyte hard drive. When this happens, I restart the computer, and the drive usually reappears. I contacted Western Digital support, and they said this drive...

My apologies if this has been posted elsewhere; if so, I hope someone will point me in the direction of the current thread. Since upgrading from Vista HP, I'm getting "consider replacing your battery" and "There is a problem with your battery, so your computer might shut down suddenly" messages...

I installed Windows 7 Ultimate today, but it's been giving me constant BSODs.They're STOP 0x7F0000 and 0x0000000D mostly. I also checked the event log and it says a critical error, code 41 on Kernel-Power. Here's the detailed log: BODY{font:x-small 'Verdana';margin-right:1.5em} .c{cursor:hand}...

I don't know if I should post this in any other forum, so here goes. I am having a problem with Win7 not coming back from sleep mode. The machine goes to sleep without a poblem. When I move my mouse it starts waking up and then just powers off. I have to hit the power button to turn it...

activated sleep mode in build 7100 had no real problems with it but then had a few glitches where it didnt sleep properly then took about 30 mins to come up and run properly as windows was just taking its sweet time loading everything as appeared to half sleep and half turn off... had no further...

I've searched up shutdown problems on the forum but I could not find anything directly to my problem. When I press shutdown from the Start Menu, sometimes it will just restart or it will actually shutdown. It is very random but I've tested when I Shutdown about 3 times, it will actually...

It all started a week ago, my computer began to restart like crazy. (I installed it approximatly 2-4weeks ago, before university started and it was fine in the first week or so) Here's an example of the classic log critical error: As for minidumps I have been unable to read the them...

I'm not sure what's going on here, I got sleep to work a few times on my Toshiba netbook, but suddenly no luck. When I put it to sleep then press the space bar to wake it, the power light turns green but nothing happens. Not a blip from the hard drive, nothing but a black screen. Anything...

Hey, I am having an issue with my Windows 7 install that just popped up last night.. The issue seems to be that it’s "stuck" in sleep mode. The PC was on this morning when I checked it - all lights, fans, HDD seems to be spinning up etc. but no video output signal. The machine looks...

I am trying to find minidumps.zip or anything with minidump, I have tried the search bar but no avail of finding anything regarding minidump, for the fact reasoning I am looking for this is that I have a new Event ID Error. Critical 9/12/2009 3:48:47 PM Kernel-Power 41 (63) Log...

I took months of convincing the most stubborn of XP users but I finally got my buddy to try Windows 7. He had it up and running for a few hours and he loved it until...his power went out. He couldn't boot up and windows 7 couldn't repair startup, he tried every option and they all failed. He's...
