@mysticusa
It's a relatively easy job, as long as you use a programmer with SOP8 clip (no soldering required). With some experience it can be done in 30 minutes or less.
In my opinion the most important step is having a backup of original BIOS (read chip and save file, do this 3 times and compare all 3 files to make sure they all match), before trying any patching of the bios.

we got another worker brought thinkpad t14s laptop with broken screen, when i replaced the lcd panel and turned on, it had bios password. this time worker doesnt remember the password. i took a look inside and saw a winbond chip (i m guessing this is bios chip?) also it still has lenovo 3rd tier (best warranty on it still) is it possible to use sop8 and the tools to reset the bios on T14s or do you think lenovo warranty will replace the board under warranty?

Hi, can anyone please help with this P52 dump. The patcher said "Done" but when I write this dump, the P52 is just showing black screen and plays a melody for about 3-4 seconds.
I am attaching both the original dump and the patched dump that gives black screen and a melody.
Thanks in advance!

Read the instructions (post #1), you have to press F1 upon powering up the laptop, once it asks for password use “1234” ENTER, then follow screen instructions.
If your ThinkPad is already unlocked, you just have to program original BIOS.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Hello,
I have t480s and have successfully dumped and patched it (I guess as no errors during the process and have a xxx_PATCHED.bin file)
Only one question regarding the "STEP 8: Restore original BIOS"? what do you mean by restore? should I flash the BIOS (same version I suppose) from Lenovo website? or should I restore it from dump?

Many thanks in advance!

Flash the original BIOS dump with the programmer. Turn on the laptop, enter the BIOS, reset it to the factory settings. Check the settings for date, time ..

You need to program the jarred BIOS dump using the programmer.
The file extension does not matter - it does not matter that the volume matches 100 percent. You can compare the original dump and the modified dump using HxD

Do i have to make a backup of my bricked or locked bios with ASprogrammer tool and post it here to get new unlocked bios, or can i use an already unlocked one from one of the postings here?

thank you in advance.
