Tell me a utility for recording all serial numbers in Thinkpad X1 Extreme Gen 3, I changed the EC and Think Engine BGA. The original one did not read, since the laptop did not respond even to the power button. BGA EC and second chip from disassembly taobao. Power on - ok, but all data invalid and beeps.
The search only resulted in instructions and utilities for older models. I tried to update the firmware and rollback, but the BIOS only stores the Windows license. Everything else seems to be in EC........
