Hello guys,
I have a laptop that does not boot and it only tries to turn on when the battery is disconnected.
Corrosion on PP5V_S0_KBD on the keyboard/fan connector. Cleaned up and fixed some of the pins. One of the redundant PP5V_S0_KBD pins are burned and not connected, will fix later.
Little corrosion around Q6000/Q6050 - insignificant amount. Cleaned up with alcohol, reflowed quickly.
Corrosion around U5256.
Lots of corrosion around U8192, U8190, U1910 - I understand there is a lot going around this area. Cleaned reflowed, replaced R1343, R8190.
Fans spin
PPBUS_G3H = 13.1v
CPU Vcore is present
GPU Vcore is present
No display internal or external
USB mouse I believe shows activity, however we need to confirm this
How do I begin troubleshooting? I don't have any donor boards for newer models yet, but they are on the way.
Picture attached.
