Lenovo L15 Gen1 NM_C631 VCCSA short to GND

[danny34]

Hello folks,

I have an L15 Gen1 (NM-C631). It has all voltages so far, but not VCCSA.

While searching I discovered the PQ1101 which burned down.



I then soldered out the PQ1101 & PL1102 and the capacitors that come afterwards. Unfortunately there is a short circuit to GND (0.2ohms) on the pink marked line.

Do you think the processor is broken? Or is it worth replacing the PQ1101?

The picture is gone. I have uploaded it again in the attachment

Does anyone have an idea?

If the high side FET shorted, then you got 15V directly into the CPU. Pretty much game over at that point.
