Thinkpad R51 no video

[radiobot]

I've just receive a Thinkpad R51 bought from ebay, it seems to have everything inside. only Battery, a few screws and ram memory are missed.
When powered on the fan works but no video, already connected to an external monitor and still no video.
Where to start checking?
Thanks!!!

Well, it won't boot without RAM.

ok good point, let me check with a memory simm mounted
i though that maybe could start and display an error or something
i should have tested first before write a post!
later will write again
thank you!

Wait, you didn't hear any beeps when you tried to boot with no memory installed? If you didn't, the motherboard is dead.

already cheked with a memory simm from other r51, and still the same: no beeps, only one light the one of a circle with a z shape figure inside.
can other test be done?? is it a dead motherboard?? maybe needs to resolder some component??

Just bury it with honours and move on...

really?? when the motherboard is dead what is the failure??

should there be something more to do

Any number of things.

should there be something more to do?

If you like the machine, you could replace the board.

any suggestion?
i think i found whats wrong with my R51:

oops!!! Maybe a new motherboard??

[Harryc]

My guess was that the wrong sized screws (too large) were used to reassemble the machine. Your only option is to replace the systemboard.

Yep a computer Vampire bit it.

Looking at that again, I'd just keep your R51 as spares...had an R40 with a motherboard fault and gained a HDD/caddy from it, and a second charger!! And more screws!
