Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hi
Do you think this bios can be unlocked in this way?
I have tried the script and it failed.
Thinkpad Tablet 10 20E4 , supervisor password on, no hint code given after three attempts, just a grey screen saying 'System Locked'.
Can't update bios within windows, window comes up saying 'Update not for this system'
I have pulled a dump from the SPI flash and extracted what I believe to be the blob from the updater tool, find them attached.
Does anyone have any hints on how to proceed?

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Just a little extra detail: This is the output of the script
The chip is on the bottom side of the main board, its a Winbond 25064FWIG 64Mbit chip which was read with a Raspberry Pi using flashtool. The dump file seems the expected lengthCode:Using UEFIReplace to inject 2 DXE drivers... [1/2] BootOption (GUID e0746c42-d3f9-4f8b-b211-1410957b9ff5) [2/2] LenovoTranslateService (GUID 826bcf56-bac4-43f4-8ea1-8cdf0a121abd) dump1.bin is corrupted or does not contain a valid dump. There was an error... Aborting.
The blob pulled from the updater seems a little larger which is strange. It also has common parts but its like it is stored out of order or something.
Hope that extra detail helpsComment

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

Hello everyone,
I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.
When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.
I decided to try flashing a new BIOS, but since I didn’t want to desolder... -

Hi, 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... -
Hello, 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,...
