I'm working on a ThinkBook 16 gen6

223147-1
448.0TF06.0011

The board has 2 X usb c ports, both show 5v @ amps

I've checked the cc1 and cc2 pins and they have 0v.

The cc1 and cc2 lines go to this component marked

87 9B
M53

This is the over protection IC.

Can anyone help with a part number for this IC.

Thanks...

Hello,

I need a BIOS file. The computer powers on, but there is no display. It seems to start up normally, but no video output appears.
The 1.8V, 3.3V, and 5V rails are normal. However, the CPU and GPU voltages are missing. After about 10 seconds, the 3.3V and 1.8V lines shut down, and the fan starts spinning at high speed.

I suspect a BIOS-related issue. I would appreciate your help.

Device model: ThinBook 15 G2 ITL
S/N: MP1YNG5C
Mainboard : FLV35 LA-K052P REV :1.0...

Thank You...
