Hi all,

I got a Lenovo [FONT=Arial]Thinkbook 16P G2 ACH[/FONT] on the bench with a botched BIOS (somehow my client blanked it). I restored the laptop and got it up and running with original BIOS from Lenovo Support website.
My problem is now that the machine details are missing in the BIOS (Serial Number, MTM, etc.)
I tried to write the details with the Lenovo Uone Tool but had now luck. It is giving me an error: "ERROR: Locate protocol with LenovoEeprom, Status=[e]. EEPROM fail when reading or writing data."
I am now asking here for help if anyone knows...

Hello, I have a motherboard from a ThinkBook 16P g2 laptop
ryzen 7 5800h, rtxx 3060
board model: bm5070 v1.4
Serial:PF38FBT5

The battery transistors burned out (Appendix 1), I removed the short circuit and connected the paths. I replaced the KBC with an unprogrammed one because I heard that it should program itself. Currently, the board consumes 0.002A on the laboratory power supply. and power light is on. The question is whether the laptop should run on the lab power supply or needed oryginal charger​? Is KBC to blame? Or maybe it needs to have battery charging...
