This weekend I was going to take my dead computer in to the shop to see what was wrong with it. I decided to plug it in and turn it on just to double check that it didn’t boot up. But it booted up! It took about 5-10 minutes to boot to Windows. I had forgotten how slow it was. Then I moved it and plugged it into the UPS, and it wouldn’t boot up, just like before. So I plugged it straight into the wall. So I’m transferring all my files off it now. I think I’ll try to sell it and put the money towards a new laptop of my own.
Err. That makes it sound like there might be something weird with your UPS.
It seems like too much of a coincidence that the computer would have the same problem with both the original UPS and the replacement UPS. Someone suggested that there might be an issue with the power supply.
