Perfectly correct.

19V no longer comes to any of the following integrations.
PJP101 PL101-PL102-PL103. I think the spark when measuring the PU301 may have burned the integrated that provides 19V?

thankyou for support.

You will have to test with another known good power adapter.

Are you suggesting I change the PJP101 Power Input? When I check the charging adapter, it gives 19V. But there is no 19V at the power input on the motherboard.

After such an accident, the first thing to check is the resistance to GND on main 19V rail at CLR and then check resistance to GND on all coils.

Hello, I took it to someone who understands laptop repair for diagnostics. Unfortunately, he said that the chip in the picture below was burned. He said that there is a short circuit in the system, if I change the chip in the picture, maybe the problem can be solved. When he measured and examined it with a Thermal Kemara, the chip in the picture starts to heat up. He said that this chip replacement process can be done with the BGA machine. What exactly is the code of the chip seen in this picture? Where can I find this chip? Can it be solved if I change it? When I look at the schematic with Boardview, it appears as UH1. Exactly what chip is this?

Thankyou.
