              Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS

              Hello everyone,

              I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.

              This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.

              I have opened the laptop and identified the main BIOS chip...

              Thinkpad X1 Yoga Gen 3 ,How to know if the BIOS is corrupted
              by Loki_Fido

              I have a Lenovo Thinkpad X1 Yoga Gen 3 for repair. (20LES3T900)
              I looked in every corner and the laptop seems fine. Its pulling 500mA but no display, no noise, nothing.

              So I assume its a BIOS issue. I downloaded the BIOS with CH341A and opened it on ME Analyser and didn't receive any errors.
              Does this mean the BIOS is fine? making it a hardware issue?

              I downloaded fresh BIIOS from the Lenovo site and used Hex Editor replace the Lenovo's BIOS into my BIOS region. But the file size ended up being...

              Summary of BIOS Whitelist Removal Problem


              Problem:
              I am attempting to remove the WWAN card whitelist from my Lenovo ThinkPad T560.
              Initial Findings:
              • My current BIOS version is N1KET58W (1.45).
              • I have a CH341A programmer and have successfully created two full backups of my BIOS.
              • I have the ability to use command-line tools on a Linux machine.
              Troubleshooting Steps & Conclusions:
              • I attempted to use several automated and manual patching methods on my N1KET58W (1.45) BIOS, including using hex strings. These attempts all failed.
              • I concluded that the
