I need a schematic too or some advice.No power at all. these two caps shorted to the ground? Board clean without liquid or any obvious damage after visual inspection. It just died acording to the owner

and danito thanks for the effort but it doesnt work. Still same problem. I believe there is some other issue with the board not BIOS related.
I'll get schematics and try some troubleshoot.
Thank anyway for help...Leave a comment:

thanks for fast reply but its still the same.
Any chance the BIOS got corrupted? Owner says laptop was working fine before he left it in the cupboard for one year or more....Leave a comment:

Hi, can you disable RAM please? Lenovo IdeaPad 3 15IML05 SN: PF1AFJMP
It powers on for about 12-13sec without display and no fan spin and goes off for the same period of time and keeps looping forever. Hope it will help.

Hi, my latop is the precision 7710 and the board is LA-C551P Rev: 3.0 (A02), which powers on for about 20seconds and powers off. No display, no fan spin, no battery charge light, CPU gets warm. Can anyone have a look at BIOS please?

BIOS from post #4 didn't work for me but the one from post #6 did.

Re: looking for HP 450 G1 boardview link if it was posted on the forum please
Hello, I have the same symptoms and in my case it was a blown capacitor C4916. (I hope as I didn't power the board up yet after removing it)
The question is is it a 22uF 25V one?
I have many donor boards and can't find this cap on any of them so far. Do I read it correctly?
Thank you...Leave a comment:
