This question is not specific to any OS. I have (a customers) Toshiba
Satellite C655, today I changed out the dc adapter and the re-assembled the laptop. Once reassembled I attempted to power it on but the screen just lit up and thats all. No bios. Nothing at all. The fans comes on and I could hear the drive going so I knew it was booting, so I plugged it into an external monitor via a vga cable and BAM.... I had picture.
I have once again pulled the laptop apart and removed everything except one ram chip, reset the bios and I get the same outcome. Just a blank lit up screen.
After all this I spoke with my customer and found out that the laptop had been freezing constantly with as little load as opening a web browser.
My thoughts are that this is video card related and that it has been failing for a while. The freezing makes me think that its more than just a bad cable from the mobo to the monitor.
Any ideas?
Edit:
Also I should have mentioned that I have gotten very close to the screen and tried to see if the display was there at all in case the display was failing but theres nothing at all
