LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

there are several ways of accomplishing this, you can use a mini programmer to read the chip while on board or remove the chip and place it in the programmer and dumb the bios. obviously not all motherboards are compatible this way. this depends on the chip itself.Comment

When did you see FL1 files being used? Everyone is talking about chip reading and programmer! It doesn't work like that.Comment

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 FilesComment

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 FilesComment

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.

by jbonavitaHi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...-

by zeniusHello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...-

by WahazHello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....-

by BloodhoundjeHi everyone,
I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.
I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.
After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.
I have desoldered the bios chip (GigaDevice...-
