We have a Lenovo ThinkCentre desktop computer, running Windows 7 Professional. It's a few years old, and for the most part has been running fine. However, it has now inexplicably died and won't come on again. :4-reaper:
We've been having a few blackouts and brownouts lately. It's not one of those computers that stays off when the power returns; if it was set to 'on' when the power went out, it'll start back up once the power returns.
A couple of days ago, it had gone into standby or sleep mode, and for some reason wouldn't come out of it. The laser mouse wasn't lit up, which often happens when a computer is in standby mode, but when I hit keys on the keyboard, it still didn't come on. After opening and closing the disc drive, and pushing the power button a couple of times, I finally gave up and held the button until it force shut-down. The next time it was turned on, however, it worked fine, and didn't seem to exhibit any unusual behavior.
So yesterday, the computer was working. It was left running overnight, as it generally is. The following morning, however, it was no longer on. Pushing the power button yields no power lights or sound of anything running. I unplugged it from the surge protector, then plugged it back in again, choosing a different plug on the surge protector. Still nothing. It shouldn't be an issue with the surge protector itself, as the monitor and internet router connected to it work. I don't think there was an outage, either, because no clocks were reset.
Does anyone have a theory on why it might have randomly died in the middle in the night, and whether by some miracle, it's something easily fixed?
