LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

[ofluffy]

This has bricked my T470s, great. Now the power button and keyboard flicker and it won't come on fully at all.

Hello friends! I used autopatcher, rewrote the patched file in the bios, but as a result, when I press the power button, it blinks 3 times. Then nothing happens. Can someone help?
Laptop Lenovo P50
Type 20EQ
Serial MJ-04TPLT

Try with this attached content.

STEP 1: Flash and replace current BIOS with the P50_Bios_2_PATCHED.bin file
STEP 2: Boot the machine
STEP 3: Press ENTER/F1/etc. to enter BIOS settings
STEP 4: Enter any character when asked for Supervisor Password
STEP 5: Press enter when it shows Hardware ID
STEP 6: Press space bar 2x when asked
STEP 7: Turn off machine
STEP 8: Restore original P50_Bios_1.bin BIOS content
STEP 9: Reset BIOS settings to factory default

Good luck!

Your model can be unlock if you provide 2kb file EEPROM container from MEC1663
No main BIOS patch available for your model

ok, thanks

Test this patched file.

Thanks for sharing.
I tried the file you shared,
I wrote it and verified it was written correctly.

It has the same problem as above: it beeps 5 times twice, the fans spin for a few seconds, and then shuts down. No signal.

rewriting my original, it goes back to how it was before with the password.

Я одразу прочитав дамп BIOS, а EC — лише після того, як перепробував many options BIOS з форумів. I immediately read the BIOS dump, and the EC only after trying many BIOS options from the forums.

still svod 4 reads EC, but doesn't want to wipe

Dump original

Post the laptop serial number and your EC backup

Does this it have a model number ? .Does it start if you flash the old bios back

After the patcher, it stopped starting at all, I tried the saved lamps, it doesn't work...

Hi,

I need a patched BIOS version for X1 Yoga 4th generation. Autopatcher did not help, the laptop beeps many times, and the screen remains black.

Hi everyone,
I'm trying to remove the bios Password from my ThinkPad P50.

I have tried both lenovo_autopatcher_0.2 and the older lenovo_autopatcher.
In both cases the generated files (P50BK1_PATCHED_CLEAN and P50BK1_PATCHED) do not work.
After flashing I only get a black screen, 5 beeps, fans stop spinning, and no other signs of life.

I am not able to manually edit the NVRAM (VSS2 store) blocks with UEFITool.

**Tools available:**
- Windows 11
- CH341A PRO (2 units)
- AsProgrammer
- 3 original BIOS dumps (compared with HxD, all identical)

**Motherboard:**
- Lenovo BP500 NM-A451 Rev 1.0 (2015-11-06)
- BIOS chip: Winbond W25Q128FV
- Machine: ThinkPad P50, TYPE 20EQ-S3WF12, S/N PC-0GSV94 16/11

I know that many users face the same issue (after autopatcher → 5 beeps and black screen).
Has anyone already found a working patch for the P50, or could you help me clean the dump manually?

Thanks!

Test this patched file.

I've tried reprogramming the backup, and I can enter the BIOS again with that. The screen is still very dim with it. (might be backlight, but I am using a brand new screen)

OK
Than connect an external HDMI screen for better view, and keep pressing the F1 key when start with the patched file. If you delay with F1 key it freeze in Lenovo screen.
