Hello everyone, I've gotten a hold of a Thinkpad W540, and unfortunately it is bios locked. really bummed out how the seller didn't tell me but here we are. I've made dumps of the 2 bios chips (25Q032, 25Q064. 4 mb and 8 mb respectively) and made sure to compare the files. I couldn't patch the 8mb dump as the auto patcher thought it was corrupted or not a correct dump. it did patch the 4 mb dump just fine. i've since then never touched the 8mb chip and just flashed the patched 4 mb dump to the 4mb chip with my CH341a. upon doing this, the laptop was essentially bricked and would not boot up. Powers on but the fans spin, no image and no beeping. I've tried to patch it and flash it a few times and removed the cmos, the external battery and the hard drive to no avail. The laptop works just fine with the stock bios, what am i doing wrong? Here are my dumps.Attached Files

Hi everyone! I'm having a problem trying to remove the password from my T480. I'm getting a weird tune on my thinkpad, and according to the Lenovo Diagnostics app, the error is 0285. Is there anything i can do? Already tried clearing TPM but nothing.
Thanks in advance!
Here is the original BIOS file and the patched one.Attached Files

If all ok you have the patched content also in the zip , write it and follow the procedure from the first post in this thread.
In short:
- Enter any character when asked for Supervisor Password
- Press Enter when it shows Hardware ID
- Press space bar 2x when asked
- Turn off machine
- Restore original BIOS
Please provide feedback.
