Hello! I tried using the autopatcher for my Lenovo T480s, but it only causes the system to beep and display a blank screen (sometimes a very dimmed Lenovo logo). I'm using AsProgrammer and have followed the main instructions in this thread. I have also tried the W25Q128JV@SOIC8_PATCHED.bin file.

I've attached my original bin file.

(sometimes a very dimmed Lenovo logo).

Are you sure you didn't do any faults to the motherboard ?
Program back the backup, see if you have POST

OK, let's see if my method works for you...

STEP 1: Flash and replace current BIOS with the attached Lenovo ThinkPad T480s_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 your saved Original.bin BIOS
STEP 9: Reset BIOS settings to factory default

Good Luck!

I had the same issue as elianadragon when using autopatcher (T480s, S/N PC-1678ZZ, w25q128jv). I tried your patched version and worked perfectly. Thanks!

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)

Thank you for responding!
After I flashed this file, I pressed F1 and got four beeps. Then it shows a faint "Entering Setup" on the screen and hangs there.

Flash your original BIOS again and check if the laptp starts ok and you can get to the Password screen.
If it's ok then flash the patched file and try again all steps from the beginning

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!

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.
