HP 15-cx0054ur (DPk54 LA-F841P Rev:1A) with a problem

[Robin45]

Hello everyone. I received an HP 15-cx0054ur (DPk54 LA-F841P Rev:1A) with a problem - it won't turn on. During the inspection, I found a faulty chip marked 8AAB0G , but I couldn't find any information about it. In the board viewer, it is marked as PUH1 , but I don't have a full schematic. According to the board viewer, this is a power controller that generates +0.95VS_VCCIO . If anyone has an alternative marking for this chip, a partial schematic with it, or any other information, I would be very grateful .
