        This is not the Main BIOS chip, I think there should be another chip on your motherboard (16MB or 32MB).

            Thanks for your answer.
            Yes, there is one more winbond chip but it's BGA. Unfortunately do not have a BGA reader at this moment.

                Sorry I was wrong the chip is SMD.
                I'll find the right reader board to solder and let you know the result.

                Thank you!

                    Hi. I have the same motherboard for which you gave the bios file. I write the chip - but then the laptop does not turn on.
                    Can you help me unlock my bios file?​

                      Fixed: Lenovo P14s Gen 1 (type 20Y1, 20Y2) Laptop (ThinkPad) bricked by a withdrawn BIOS update (r1buj82w)
                      by akwky
                      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...

                      So far I've been a silent reader, but now I need your help

                      I bought a laptop. The seller said the bios was locked. I was looking for a way to remove this ban.
                      I then got the CH341A and pulled the corresponding files from here https://www.badcaps.net/forum/troubl...evices-and-ele...
                      The laptop was brought in with a BIOS problem and a password. After reading the dump, the information was damaged. I ask for help in the BIOS with a clean ME region. Motherboard 213035-1. Serial number: PW+04e998, Type number: 21c3-0016ge

                      Should I buy a Lenovo Thinkpad E495 with bios password?
                      by RMDUiFT
                      Good day. I apologize if I posted this in the wrong topic. I saw somebody selling a Thinkpad E495 with a Ryzen 3500U CPU near me. In the pictures the laptop is running windows 10. I contacted the seller and asked a few questions about upgradability and if it has a bios password on it. He confirmed it has a bios password. I searched through the forum, I found a guide regarding removing the bios password using the autopatcher, I also found a thread with the e495 where people requested help with unlocking the bios password.

                      I have a few questions:
                      • If I would buy this laptop and have

                      Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
                      by Wahaz
                      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....
