Solved Computer Suddenly Went Black

June 11, 2012 at 23:35:03
Specs: Windows XP, 1.8 CPU/ 512 RAM
I was running a program. It appeared as if there was an error and a "bug menu" appeared. There was a dialog box of details, which I didn't read. The options were the boxes of "ok", "cancel", "debug", and one other option. I clicked "debug". It looked like it didn't do anything or resolved really quickly so I clicked it again. I clicked it one more time. And suddenly the computer shut off within 1 second, not a long shut down where all programs shut down slowly and windows logs off.

Now the computer won't turn on at all when I press the power button. It has never done this before. I waited several minutes and pressed the power button again. The computer won't turn on, nor is there "any" lights that are on on the computer -- even when the power cord is plugged into it...

✔ Best Answer
Before i recommend trying another power supply, can you try the following:

1) unplug the power cord from the back of the machine, then hold down the power button on your PC for 10 seconds. This will discharge all the capacitors in your power supply. Plug the cable back in and see if that has helped.

2) if not, then open the case of yuor pc and reset CMOS.

3) if the above does not help then you will probably need to try another psu.

AlwaysWillingToLearn, thanks for your reply, I REALLY appreciate your response at this CRITICAL juncture!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I left the computer off for about 1 day. I pressed the power button. It, again, still would not turn on. I held down the power button for 10 seconds like you said to discharge any possible remaining electricity that might still be in it. Then I plugged in the power cord. I pressed the power button and it still would not turn on!!! When the power cord was plugged in, there were no lights still on the computer at all!! This is strange.

I unhooked the power cord. Okay, looks like I'm going to have to open it up then. I opened it up. The first to come off, was the lid to the RAM case? It is the smallest box on the laptop in the back -- I'm just guessing; I'm not really all that familiar with laptops, I mostly just know desktops. I looked in the box and saw an empty circular slot. Is this where the CMOS battery is supposed to go? Looks like the person who I got it from didn't include a battery with it. Guess I'll need to get one. That's good to know.

No wonder I keep getting the message that pops up the screen every time that I boot about, "you have the wrong date and time", or something or other. Okay, well, looks like I don't have to reset the CMOS then. So that's out of the way. Well I don't really know what to do next, and this computer DOES NOT work so, guess its surgery time. Looks like I'm just going to disect it. I lightly jiggled the RAM metal rails on the side of the (RAM chip?) to see if it was a lever to release the chip or what exactly that it was.

Don't really know what I am going to do at this point. I did everything you said, aside from trying the new power cord, so I guess I'll just try the basics and go from there. So I took out the rechargable battery out of the back. I examined the empty hole. Nothing looks out of place there.

Then for some strange reason, I got the idea to try to plug in the power cord and to try to plug it in. It was just going to be one of those trial and error, hit and miss days I guess. I plugged in the power cord. The laptop was still upside down. I pulled it open, to open the lid to reach the power button, and all the weight rested on the power cord connector peice to the computer. Hope I didn't torque it any. The I pressed the power button and "whooom!!!" -- IT TURNED ON!!!!!!!!!!!!!!!!!!!!

So now the computer is on without the rechargable battery. But its probably better without the rechargable battery anyways because I only the power cord for it anyways, as the battery only lasts for a 2 hour duration which is barely enough time to wink for a computer junkie.

Thanks for all your help AlwaysWillingToLearn, you fixed it!!!!!!!!!!
