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... -

Hello dear forum members,
I own two Lenovo Yoga X1 Gen 4 laptops. One of them had a touchscreen problem, and I tried to fix it by externally flashing the BIOS. Unfortunately, I didn’t save the original BIOS and accidentally flashed it with a faulty one. After that, the device stopped working completely.
I then had the idea to make a BIOS backup from the other Yoga X1 Gen 4 (same hardware) and flash it onto the non-working device.
Nothing was flashed here — the BIOS was only backed up.
I created the backup using a CH341A Black programmer and NeoProgrammer.... -
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.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V.... -
