Dear all, I found this forum and this is my last hope. I had a problem with BIOS update though Windows Update - it was stuck for an hour and I decided to restart. Then it bricked. The reason to update was, I had no video on my panorama display. I tried to find a BIOS on my own, but it seems that Lenovo doesn't provide a complete file, only the BIOS section. Is there any chance someone could repair it? I did a backup from the chip, attached. I also tried using another BIOS, slightly different revision. It worked and even I had a display working, but then Windows tried to update once again and it bricked. (from this thread: https://www.badcaps.net/forum/troubl...54#post1601754 ). Should I provide anything more? Some steps to do? Many thanks!

I am sorry for another reply, I couldn't find an option to edit my post. I managed to reprogramm BIOS, so the PC is working and seems to be everything okay, except of the serial numer. Could please anyone tell, how to repair it? Still, I will be really glad if someone could confirm, that this solution won't harm anything. Thank you. -

Hi!
Went dumpster-diving and found a bricked Lenovo P14S in trash, few weeks earlier. Symptoms - no screen, no POST, no beep, just keyboard LEDs flashing on powerup. Mute button+LED was responding though, and the display self-test was still working (via the key combo Ctrl+Fn+Power held for some seconds, see the Service manual).
Incidentally, Windows 11 have recently started auto-flashing computer BIOS in our region. Even more suspiciously, Lenovo has released a BIOS update just few days before the PC was trashed. About a week later, the BIOS update image has been oficially marked...04-14-2025, 01:56 PM -

Hello!
A few days ago I bricked my Lenovo x1 nano gen 1 while updating the bios/fw from linux.
No the machine power up, but it stuck in a recovery state and I can not do much.

I would like to flash a new BIOS/FW on the chip using a CH341a programmer but ... I actually don't know which "chip" on the motherboard to target 🤦♂️
So here I am to ask for help.
I opened the laptop and I found a chip that may be the target, on it I've:

Hi, I have a few of these & they came with a custom bios boot logo, no passwords etc.
2 x were brand new unused but with custom boot logo, 1 I installed Windows/ran updates then it bricked itself. 1 wouldn't get past the custom bios boot logo.
The third I loaded windows, took a backup of the bios chip, then tried to flash several different clean bios's via programmer which all caused it to not boot. I tried to reflash the original bios both using clip & desoldering but... -
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...
