Here I have this Sony laptop that is dead. Upon opening it saw SMD capacitor almost burnt . I did remove it and haven't replaced it yet. The board still not not start. I want to know is it essential to put a new one ? I have also flashed the bios chip with a new one and still nothing happens.
Also from what I have observed.. the bios chip ( Pin8 ) has around 1 volt..
The power button has around 1.5 volt..
5 volt and 3 volt Always is present though.
I have attached the two images .. 1 of the capacitor that was burnt and the other that produces the AC_OK signal and I want to learn how that works..
ADAPTER SECTION of THE IMAGE
PR187 has 19 V on one end and on the other end it is 0 volt. Is that normal ?
BURNT CAPACITOR IMAGE
PC 61 was burnt and short as well.
Thanks everyone for your time.
