The motherboard battery is only used to preserve the real-time clock and CMOS settings. Hibernation saves your computer's state to the hard drive.

The power button settings are, in both XP and 7, under "Power Options" (powercfg.cpl). Also check the security policy (secpol.msc) – you may need to add Everyone and Anonymous under Local Policies - User Rights - Shut down the system, but this probably won't affect the power button (just the lock screen). If the disk is not being actively used ...

Off of the top of my head, I'd guess a bad power supply. You could check it with a power supply tester, but sometimes they don't fail unless they are under load. As EKW is pointing out, you could be looking at some sort of thermal shutdown. I guess I could believe a year in the right conditions dried out whatever thermal compound is installed and left ...

For any device, it is certainly best to power it down before removing power, as you stated. But once this is done, it really doesn't matter how quickly you remove the plug, only that you pull it straight out to avoid bending the prongs. When you remove the plug, there is going to be a point where the connection is broken. No matter how slowly you remove ...

I had a motherboard that did that. The cause was I accidentally installed a 1394 cable into a USB spot and it permanently damaged the motherboard by putting voltage where voltage doesn't belong. It exhibited the exact same symptoms. I lucked out because it reset seldom enough that my computer was still mostly usable. It's a common error, and if your ...

It is very possible that this is because of a fan issue. Make sure your fans are running well and that your computer is not overheating. Overheating on a computer will cause it to shut off immediately so that it won't ruin the hardware. If you have a broken fan, the machine will overheat quickly while playing a high performing game such as Diablo 3. If it is ...

poweroff is the proper way to do this. shutdown -h is exactly equivalent in Debian/Ubuntu (and most other systems).

I can think of a few immediate causes involving the power supply. You got a lemon and the fan isn't working properly and overheats. Another possibility is that your PC is trying to pull more power than what your PSU can supply. How many watts is the new PSU? Added: With this new revelation of an amber blinking power light, Dell says this: If the power ...

If the laptop is heating up, that is very likely the problem. I would recommend you test it but since you can't boot that might be kinda hard... Ideally, I would leave the laptop on at the BIOS temperature monitor screen. Try that if you can manage to make it boot again. If it is a heating problem you could try the following: Open the laptop up and clean ...

You have to open the power supply to do it, but you can use a zip tie to hold down the "on" side of the switch.

What you are suggesting is never going to work. Among all the things, hibernation saves what is currently in memory and executes shutdown. It only works because shutdown makes sure that system does not change state (no changes to disk, files etc.). Even if hybernate would support it, you would not be able to use it as a "snapshot" as otherwise you would ...

Try this: sudo shutdown 0 I have ubuntu and this is how I turn off the system.

I believe that I've found the answer. Notsosure's link to the Toshiba thread really helped in figuring out the logic behind this mess. What's happening is that certain capacitors on the motherboard that regulate the current of the CPU have started to fail. So whenever the CPU changes its clock speed or multiplier, the capacitors do not deliver the required ...

My best guess would be the power supply as well. Just because it has enough watts doesn't mean there isn't some other problem. Can you get ahold of another PSU just for testing? Another thing to consider is how good of a heat sink do you have on your CPU? If the video card is throwing off a lot of heat, it can be adding to the heat of the CPU. Modern ...

First thing I'd try (if you're not already) is using a mains powered USB hub. Maybe the printer is pulling just enough power to knock your Motherboard or PSU over the edge.

I found that not all my USB ports on all my computers are the same. It matters very much WHICH USB socket (& port) is being used. If you have a modern USB connection, it gets worse, with USB3, etc. I assume you've checked that it is not a cable, nor the scanner's problem? AFAIK most printers have a self-test mode,independent of any connections ...
