Just had a customer bring in a HP 14s-fq1010nm to do some maintenance.
After updating the BIOS to the latest (F.35) I get black screen (no backlight turning on). However the backlight turns on if I connect an external display to HDMI, but when booting to Windows, both displays remain black.
After disconnecting internal LCD, and plugging in external display via HDMI, it works on external.

I tried downgrading it using official method - using an USB drive with older BIOS version, but it fails, saying that the BIOS files are corrupted. I used about 5 different older BIOS versions...

I decided to restart the computer but got no video.

The thing is that I had installed TeamViewer and could log into the computer...

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.
