                          solution you have on link above. So what you need more ? Read and make patch and unlock.

                              Lenovo ThinkPad T450 bios password decrypt

                              Hi all.

                              I have Lenovo ThinkPad T450 with supervisor password. I was able to install Linux but I want to be able to make changes in BIOS.

                              I used clip ch341 and successfully read W25Q128.V bios on Thinkpad T450

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




                              I was trying write files from forum for T450 but without success. If I use my backup I am back to beginning... computer is starting but BIOS is locked.

                              Thanks in advance

                                          Hi Everyone,

                                          I'm facing a problem with a locked bios with a password and i can't find how to remove it...

                                          The small computer is only booting on a M2 ssd Windows partition and i get a "signed partition error" if i try to boot on the same SSD with another Os (linux for example).

                                          the Computer is a Unowhy small pc
                                          N° UYM6524702229


                                          After failling trying to boot on other "none Windows" partition, i wanted to try to remove the bios password.

                                          My first attempt was to get the bios dump from windows...

                                          Good day, everyone!

                                          I'm encountering an issue with my Lenovo X1 Yoga 5th Gen laptop related to the BIOS supervisor password. I'm seeking assistance and guidance from the knowledgeable members of this community in resolving this problem.

                                          I am no expert and cannot perform soldering or unsoldering of the chip from the board. Therefore, I attempted to use an EZP 2023 programmer with a clip to extract the BIOS bin file without removing the BIOS chip from the motherboard.

                                          Need BIOS Dump/ROM for Lenovo Thinkstation p500

                                          Hello all,
                                          I have a Lenovo Thinkstation P500 that is stuck at post with no display, it happened after I changed the memory timings in bios. I can not clear CMOS using the jumper on the motherboard, also tried re-flashing bios suing a USB stick but it also doesn't work. The only solution that I can think of right now is re-flashing the bios chip using an external programmer but the problem is that I don't have the bios dump of p500 for flashing externally and I don't know the location of bios chip. If someone can provide the bios dump and bios chip location it would be really helpful....

                                          TONGFANG "GM7TG7P" Bios Password Problem?

                                          Hello,

                                          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...
