      Type 20J1. I believe the bios for Thinkpad S2 will also work as it has the same motherboard. But cannot find that either.

        Can you post your bios backup.The bios from lenovo is only a bios update,i can merge it with your bios.

          Thanks but I try this already and it doesn't work. My bios is completely corrupt from the beginning due to a loose contact on the programmer while I was reading it, then I write another wrong one and is all gone now.

              Re: Lenovo ThinkPad 13 gen 2 - BIOS Request

              Thanks it works. But is asking for a password when I try to go to settings after the message that rtc time needs to be set and to press F1. It doesn't give no other boot options. Is that kind of password with a human head, I think is a supervisor password. Can this be removed from the bios or is embedded on the security chip?

                Re: Lenovo ThinkPad 13 gen 2 - BIOS Request

                I also get the message
                0183: Bad CRC of Security Settings in EFI Variable
                Any way I can bypass this on Hex Editor so the computer can boot?
                I cannot go to F1 Settings because is asking for Supervisor password.
                I believe these error messages are because the computer detects that is another bios installed.

                  Re: Lenovo ThinkPad 13 gen 2 - BIOS Request

                  I manage to get rid of there error messages by restarting many times the computer with RTC battery plugged and its main battery. It boots normal now but still have that password on bios settings. If I just press ENTER it goes to bios screen but won't allow me to do any changes. I think I need a mini UEFI bios boot tool to flash on the EEPROM chip to reset these settings. Do you have any of these mini bioses please? It will be a great help. And Thank You once again for providing the working main bios.

                    There must have been a password on the original bios,and i think it does indeed have a MEC1633L or similar chip,so flashing the bios and EC wouldn`t remove the password,if you had those dumps.

                        I hope someone will finally upload a DXE Driver so we can modify it to sort out these IBM's Passwords problem once for all.
                        Many Thanks in advance.

                              Hello, Can anyone tell me if Lenovo Autopatcher v0.2 works
                              for this model ? I have done a few readings with two different programmers
                              the files are identical, Lenovo Autopatcher is telling the file is corrupted.

                              And is the password on the main bios or EC.

                              Lenovo ThinkPad 13 Gen 2, Type 20J1, 20J2. Thanks.

                                          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....

                                          Hello everyone,

                                          First, the data in brief:

                                          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:

                                          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...

                                          Lenovo ThinkStation P720 BIOS Request
                                          by HammyCheesy
                                          Hello all,

                                          I'm trying desperately to revive a ThinkStation P720 that I purchased from a seller who claims it suffered a "failed firmware update."

                                          When given power, the machine turns on, spins up fans, beeps a single time, fans slow down, then a beep code is sounded repeatedly (3 high/short tones, 1 low/long tone).

                                          Type: 30BB
                                          Model Number: S03600
                                          S/N: MJ07N68C

                                          Things I have tried:

                                          1. Reseated all components, pulled everything except for 2 RAM modules (1 per CPU)
                                          2. Attempted to boot with just a single CPU...
