Summary of BIOS Whitelist Removal Problem
Problem:
I am attempting to remove the WWAN card whitelist from my Lenovo ThinkPad T560.

Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.

I searched for this error online and discovered... -
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...
