The standard method is to inject voltage and see what gets hot.
The capacitor indicated is the C2550 which is on the VCC3M rail.

My ThinkPad E14 Gen 1 (NM-C421) only lets me install Windows if I provide a company email address.
When I tried to clean ME, I got the following errors:
MEAnalyzer: Error: Detected MFS Low Level File 12 which has not been parsed!
Flash Image Tool: Error 113: [Nvar Actions] Detected error in buffer parsing operation. Ivalid ICC PLL NVAR icc/pocdatasize
Could someone please provide a fixed BIOS?...Last edited by rumpumpel1; 07-07-2025, 02:09 AM.Leave a comment:

Based on the comparison between my EC dump and the proper section ($0AR1M00.FL1) of a BIOS update archive I tried to figure out which region contains the password.
It looks like that filling the region (6 lines) starting at 0x000492F0 with 0x00 does the job.
Use this info with care, because I'm not an expert on this.Leave a comment:

please can someone tell me, which region of the EC dump I have to fill with 0x00 in order to remove the BIOS password?
