Hi,
I have Lenovo S340-15IWL with LA-H101P motherboard after water damage. Damage was near audio realtek chip (UA1) and input mosfets PQ312 PQ311. I cleaned everything, not soldered realtek yet, but this is not a problem. Bios has clear ME.
Problem is that after power it takes 20mA, after switch clicking it takes 0.6A, led is still on and CPU + GPU is starting. Fan is working for 3 sec. and then it is switching off for some time, then it is switching on once again, I think because of the CPU temperature. I have all voltages on. On thermal camera I saw that onboard RAM is not starting, so I think that might be the problem. Second thougt was that I don't have one element on board, maybe you can help me identify it... I attached photo (it is before I replaced this bad capacitor)
Do anyone know what to do?
This laptop is after some crappy service, so please don't tell me how bad this soldermask looks - I know.
