I've never been unable to figure a desktop out. Even with a cheap 'integrated everything' Dell or some such, there is a lot I can do to nail down a faulty part.
Notebooks are obviously a little harder. I've got one right now where I can't think of anything to do other than replace the motherboard. And that's a pretty big leap for something I'm not sure of.
It's a ~2010 model Toshiba, L675D. Phenom X3, 4GB, Windows 7. Stock.
When you turn it on, the cooling fan operates normally. Cycles on and off (and maybe changes speed? can't recall if it has that capability). Heatsink gets hot but not overly so. I can hear hard disk activity, but I've never seen the light on the front blink (at least, I think that's a HDD light...).
Zero activity on screen. No backlight observed. I've plugged in a VGA monitor and gotten nothing. Have not tried HDMI yet.
Because of the display issue, I have no idea if it's even booting. I've done the typical things...waited a reasonable period for it to boot. Tried striking the enter key a few times in case it's hanging on some kind of error/option. I never hear the 'welcome' noise. Don't hear anything when I adjust volume with function keys (should I? can't remember). Don't hear 'goodbye' noise when I hit the power button. Have to do a 'hard' shutdown (hold button). Oh, and I've tried the function key for switching displays, too.
Is there anything else I can do to troubleshoot? At this point, I'm reasonable suspicious that it's hanging on post or something, but I have no way to verify. Could be locking up while loading into windows. I don't know what would cause no monitor AND no boot, other than a GPU failure, I guess?
