@lamo
Search the forum and find a ThinkPad T470 patched bios, this one will only be used for the unlock procedure, once unlocked you can use the Original BIOS.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Hi.
Thank you for this tool. I've got many successes with unlocking T470 and T460s so far.
Today I have Lenovo T540P with 2 spi chips, after reading some posts from this thread I've desoldered the 4MB chip read it and put it in the Autopatcher and flashed it with patched file.
After powering up the laptop I have a blank screen with 2x 5beeps.
I flashed my original file back and everything is back to normal.
It would be great if someone could look into my original file and try to patch it.
Thank you

I would like to add that I had the anti-tamper switch taped and CMOS battery disconnected.
Later I tried to boot with a previously locked hard drive but without any success
After patching laptop always does 2x 5 beeps and the screen remains black.
Sorry for not editing my yesterday post, but the edit button is gone for some reason.

Hello! I am asking for help in removing the Thinkpad T540P bios password! I read a forum, I used this: https://www.badcaps.net/forum/showth...ht=t540p+patch
it doesn't work for me. if I do it based on the description, I write the bios, the machine turns on but does not show an image. The display is black.

Hello, is this thread still active ?
The software says that my dump is corrupted or does not contain a valid dump. I Have quadruple checked it and the checksum is OK.

Oops, I'm new to this, I didn't archive the dump so it wasn't added. Sorry. Here it is.
One dumps permissions and ownership were scrambled, so I fixed them to 755 and one to 644 (default result). The result stays the same

@Merlinox
That error is because your chip dump is only 1MB, you need to look for other chip that may be located near uProcessor, RAM slots or EC/KBC chip.

Thank you so much for your reply, it did strike me as weird that the dump was this small.

This chip was hard to find. It was indeed a 20Q128 instead of a 25Q80

The chip is under the keyboard for lenovo P50 20EQ. You HAVE to take a part the heatsink.

Cheers, you saved my day !

I’ve just sent you a PM with links of 2 pictures showing BIOS chip location on ThinkPad P50.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

I have successfully patched the BIOS dump and flashed it. Steps 1-7 went smoothly,
I was told "TPM certificate changed. Turn it off." during the process.
@AAAC pointed out that this means that the laptop is unlocked.

After rebooting, the laptop posts, I can press enter to enter the setup, then the laptop beeps 4 times and shows the following messages:
"0271: Check date and time settings
0183: Bad CRC of security settings in EFI variable
Press F1 to enter setup"

Upon pressing F1 the screen stays backlit and the keyboard works (num lock toggle + fn lock toggle).
It stays like that indefinitely.

The issue persists with or without SSD plugged in.

What more can I do ? Did I miss a crucial step ?

I scrupulously proceeded with data integrity checks at every possible step.

edit (solved):
STEP 8: Restore original BIOS
means reflashing the first BIOS dump

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Try going to the Microsoft Store from your PC and search for "python".

Install the latest version available Python 3.10.

I got it to work, but the autopatcher did not work for my bios.

Hope it works for you.
