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!

Setting VPD information on System Board - ThinkStation P-series - https://support.lenovo.com/gb/en/sol...ation-p-series -
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.Comment

It worked. Thank you very much! In conclusion, it was safe to take BIOS from the mentioned post and program it to 30B8. Then I used your link to repair the missing information.Comment

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.
Lenovo X1 Nano Gen 1
Type: 20UN - X021US

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...
