Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
thats just for mec1663 and mec1653 sorry. i would assume for mec1503 you can just connect jtag tms tdi tdo tms and select same profile in rt809h since the datasheet shows the jtag protocol is very similar. haven't gotten in a newer machine to try yet thoughComment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hi guys, registered here since I need some help with SVP unlocking for my friend Thinkpad P72 bought two years ago second hand and seller is vanished to ask him about the password.
I am attaching info page from bios. I can solder with tipped iron and have a CH341a but I am far from a professional in this.
Trying to go through all the post in the thread which is quite time consuming. If anyone can point me in right direction to save some time please do. Like as of now I do not even know where is efi chip is actually located on the motherboard))Attached Filesif you find these attachements useful please consider making a small donation to the site

Install Python for Windows (don't choose the latest version - for example v. 3.10.0 is OK)

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
I need thinkpad maintenance utilities V2.01 and hope someone can help me. I learned that the tool also has a hidden function 5-clear PWD in our thinkpad maintenance utilities V1.11 old version of option 5 is directly blank, or someone can study to turn on this hidden advanced function, This will bring a breakthrough in unlocking the BIOS lock! Thanks in advance to the engineers who worked so hard!Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Should this utility work with a Lenovo E50-80, or is it specific to Thinkpad models only? I tried with the BIOS from this model and got an error:
Using UEFIReplace to inject 2 DXE drivers...
[1/2] BootOption (GUID e0746c42-d3f9-4f8b-b211-1410957b9ff5)
BIOS_Original.bin is corrupted or does not contain a valid dump.
There was an error... Aborting.
As far as I know the BIOS image is valid - it's certainly a verified copy of what's on the chip at present. I've attached a copy for reference.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
That worked - thanks so much!
As soon as I saw it I realised that you were onto something - this laptop is being refurbished for charity, and a lot of our systems are donated by schools when they upgrade.
Would you mind explaining how you worked it out, so that next time I can be self-suficient?Comment

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,...
