820-02536 no keyboard/trackpad

[Sr. Robot]

Supposedly keyboard and trackpad stopped working after LCD replacement, but angle sensor works good and its oem.


PP3V3_S2SW_IPD_F is shorted. I am unsure as to how much voltage to inject since its first time working with this model.

Did you remove LT402 and locate the short on its pad 2?

Do not inject more than 4V ever.
Depending of the short value, 1V may be good enough.
