Dead Toshiba Satellite Pro L20

[olmer]

I have been given ?faulty? Toshiba Satellite Pro L20 which had presumably overheated (was running on the pillow (with fan intake covered) and switched itself off for good).

So far i had removed everything and mobo appears intact. I had cleared CMOS and disconnected the battery, reseated CPU and tried to boot to internal/external screen with no effect. It starts okay, fan spins and responds to keyboard/shortcuts buttons/ addresses optical and HDD but gives no video output.

I cannot test memory/CPU separately and these are the only replicable parts apart from mobo.

Any ideas would be very welcome.

you said external video doesn't work? did you hit the corresponding key on the keyboard to switch internal/external?

Yep. Its Fn + F-something ? i have tried it quite a few times. It reacts to wireless/reset/caps, powers up/down and changes corresponding LEDs but gives no beeps whatsoever. And this funny Toshiba board has no led indicators. I?ll try connecting an external speaker now, but do not think it is the case. Some sort of nVidias graphics is integrated according to the sticker. Also you cannot hear any clicks/sound interference once it switched on/off as you normally do if you put volume high enough.

almost sounds like a bad bios flash on a pc motherboard.

there's a site that says you can turn it on with f12 to flash the bios, did you try that? i doubt it'd do anything, but it's worth a try.

Hmm. I just removed HDD and put a windows install disk and its apparently reads it and tries to load by the sound of it. F12 does not do anything. And there is an audible click when you start up (through headphones). Can i test monitor somehow?
