Hi all, new to this forum but notice there is a lot of helpful information here to be tapped into!
I have a large number of faulty laptop motherboards, a lot of which are graphics problems which I can fix by reballing the GPU. Apart from the obvious ones that show evidence of liquid damage, I have some that show no life at all. The motherboards are all from the same model of laptop so I am using all the correct components (RAM/CPU/power) to get them individually tested so this fault lies in the motherboard itself (guaranteed).
I was wondering if there was a common generic problem that may prevent the laptop from showing ANY signs of life at all (i.e. no LED's light when the power button is pressed)?
There are voltages present at certain points on the motherboard, so power is getting through in one way or another and as the power button is a connectable item which is common in the working/non-working laptops, the fault can not lie with this either.
If there are a series of tests that can be done to highlight a certain component (capacitor/diode/IC), I would be grateful to gather this information from you guys
If there is any additional information that you need to help, please let me know and I will post it straight away.
Thanks ...... and heres hoping!!
