by to5it0Need 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...2 Photos-

by maesonHi dear Badcaps-Community,
Somehow an auto update, which I triggered before I left my laptop unattended, bricked my BIOS.
I was able to extract the 2MB BIOS and 16MB BIOS which I will attend. (CH341B black with NeoProgrammer 2.2.0.10)
The Device is a Lenovo Yoga L13 Gen3 and I was able to identify the following specifications:
Lenovo Yoga L13 Gen 3 AMD:
Lenovo Modell: Type 21BB
Artikelnr.21BB006GGE
Seriennummer: PW0A6207
AMD Ryzen™ 5 PRO 5675U
Memory 16 GB DDR4-3200MHz
SSD: 512 GB SSD, M.2 2242, PCIe Gen4, TLC,...-

by dragic98Model: Lenovo Yoga Slim 7 15ILL9
Machine Type Model: 83HM
Motherboard ID: LNVNB161216
TLDR: I would like to have the clean BIOS dump file for my laptop model.
Issue: First, my speaker wasn't working/showing up, so I downloaded the recommended BIOS update (from Jan 4, 2026) on Lenovo Support for my laptop. This didn't fix the speaker issue after restarting, so then I shut it down and pressed the power button for 60 seconds to perform a reset. I'm guessing I somehow messed up the BIOS because now the laptop won't turn on even after trying the NOVO button on...-

I have a Lenovo Yoga 14IRH8 (N1CN BIOS).
The BIOS update via Windows failed and now the laptop does not boot:
- Black screen
- Fans spin
- No POST
- Crisis recovery attempts fail
I have read the BIOS chip (Winbond 25R64JVSIQ, 8MB) using CH341A.
I need help fixing the BIOS dump.
Attached in zip files:
- Original backup (backup1.bin)
- Lenovo BIOS file (WinN1CN15WW.fd)
Thanks in advance!...-
