                                    Hi all
                                    just came across this forum when searching for info to reset a ThinkPad T470 supervisor password. Quick question to get me started on my journey.

                                    Can i use a raspberry pi to read/write the ThinkPad T470 bios chip (W25Q128JV
                                    ), i found some instruction on youtube but i would like to check before i start messing - https://www.youtube.com/watch?v=vgbWtxv_hqM

                                    Thank you in advance

                                      After reading some posts on this forum in regards to Thinkpad T470's and the supervisor password resets ive got a SOIC8 clip and a raspberry pi and i believe successfully read the W25Q128JV bios.

                                      Can anyone help me with removing/reseting the supervisor password section from this .bin file

                                      Thanks in advance

                                          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

                                          Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                                          Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

                                          I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).

                                          But today it's not accepting my password. I'm %100 sure i'm entering the correct password.

                                          I'm trying to reset my bios without success.

                                          I tried :

                                          -I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries...
