Lenovo ThinkPad Z13 JZ3A0 NM-E071 Rev.1 no power, usb-c stuck at 5 volts

Looking for help.
I have a Lenovo ThinkPad Z13 JZ3A0 NM-E071 Rev.1, charging stuck at 5 volts / 0.09A.
According to the customer, he tried to replace the battery himself, and this is what happened.

I suspect that one of the two USB-C controllers (U5401 OR 5301) has failed.
Can anyone confirm that?

Presented voltages on a board:
(measured on coils)

PL1901 - 3.3v,
PL0501 - 3.3v
PL0202 - 5.14v
PL1601 - 1.8v
PL1401 - 0.75v

Any help appreciated....

Would you please help me to clear the BIOS for HP EliteBook 840 G4
During the Windows setup process, it prompts you to enter the company credentials.
