I have a Toshiba A100-080, an old laptop but still doing its job.
Sometimes, while I work on it, the screen suddenly goes black and after 2 or 3 seconds, the computer restarts.
Generally, this behavior occurs while I'm typing on the keyboard or when I adjust the screen's position or when I press on an area near the screen (for example where the hinges are) so I thought it was a hardware problem (a loose contact or sth like that) but then it began to happen even if I'm nowhere near the PC.
Also, when I restart the PC after it shutting down like that, it always gives a long beep then it starts with the screen still shut but it does start because I can see the HD's light indicator flickering. So for it to work properly, I have to adjust the screen's position and start the PC again and again till it actually works.
I tried to test another secreen so I hooked my desktop's monitor to the laptop but the problem is still there. And I changed the Power Saving settings for the screen to never shut it off, but nothing changed.
I just don't know what's the nature of the problem, is it hardware or software?
Please, I appreciate any suggestions
Thanks in advance ^^
