Can you help?

Hi There,
I'm reading in this forum since a long time - it's an impressive source for solutions
Today I decided to test the autopatcher. What should I say? Works like a charm.
Thank you Knucklegrumble!
Tested with a Thinkpad L560 and CH341 programmer (delivered as full 3.3V version - no need to modify) running Neoprogrammer V2.20. The programm reportet the device as CH341 black.
Tried to read eeprom in circuit with WSON clip and testclip. With 8 cycles I have 4 with identical CRC32. After also removing the BIOS battery (main battery was already off), CRC32 was identical 3 times. First flash of autopatched file went wrong. Decided to desolder chip. The problem seems to be the contact with the testclips (tried two). The file from the 3 times cycles with identical CRC32 contained the correct bios bin - lucky me
Flashed patched file external, soldered and followed instructions.
Desoldering, flashing original bin and the password was gone

Kind Regards & Thank you!!

Hey!
I need help with a P50 laptop...

Model: Thinkpad P50
Type nr: 20EQ-S20D00
Serial Number: PC-0M8XE7

What I have done so far:

- extracted BIOS
- extracted BIOS again to check/compare files: OK
- patched with autopatcher
- injected the patched file
- laptop blinks but DOES NOT power on (thermal system and fans plugs attached)

If I disconnect CMOS battery than laptop boots BUT I cannot "continue" the autopatcher procedure and, obviously, password is still there... :-(

BIOS dump is attached, any advice?

UPDATE and My bad: I had a faulty keyboard...
All has worked flawlessly...

Thanks!!!

Hello,

I have a laptop with supervisor password as below:
Model: Thinkpad P50
Type: 20EQS3G11S
S/N: PC0ULEHX
BIOS chip: MX25L12873F

Story:
I tried as in the first page and also as in this video: https://youtu.be/ja2zptfgs3I

I read the original BIOS three times, compared them with HEX editor. They were OK.
Used auto patcher and auto patcher 0,2, in total three times did not help.

After the patched BIOS was written I clicked READ button, saved that and compare it with the patched BIOS using HEX editor, they were not the same. This happened for three times.

It was only black screen with 5+5 clicks. No boot. Then I returned back to the original BIOS and it works as before.

I attached original BIOS and the other BIOS files.

Could you please help me on this issue?

Thanks!

Keep your original dump as is !

STEP 1: Flash and replace current BIOS with this patched 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 BIOS
STEP 9: Reset BIOS settings to factory default

Hello everyone, could you please help me patch the BIOS on my Lenovo T490s
FT491/FX390 NM-B891 Rev 2.0
Thx in advance

I forgot to mention: I tried different BIOS versions, including "universal" ones with the Supervisor Password already removed for the T490s, but the laptop does not respond to the power button with them. Also, with the patched BIOS, the laptop emits short beeping sounds after some time. This version of the program is apparently no longer compatible with the T490s BIOS.

Therefore, I still require assistance with the BIOS modification. Thank you.
