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 FilesPremium supporters get full download access and other benefits.

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’m hoping someone can help me locate a verified original BIOS dump for my Acer laptop.
This is NOT a BIOS password removal request.
I’m looking for an original 32MB SPI BIOS dump to use as a reference in case my BIOS firmware is corrupted. My plan is to first dump and back up my own BIOS as soon as my programmer arrives. I am not planning to blindly flash someone else’s BIOS.
Laptop Information- Model: Acer Predator Triton 16 PT16-51-99GL
- Motherboard: DA0ZQDMB8AE Rev. E
- Main SPI flash: Winbond W25Q256JVEN (32MB)
- Secondary

Hello everyone,
I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details- Barebone / Chassis: TongFang GK7MRFR

Sorry for the long story. I have a Dell Latitude 5530 (i7) laptop (South Peak 15 MLK MB DDR4 203102-1 FK8VG$JA) with an admin BIOS password that I want to remove. Service Tag: HYKFPT3. Other than that the laptop worked OK.
I found a CH341A Black and went looking for the BIOS chip on the motherboard. After trying to read one chip that was a firmware chip but not the BIOS I think I found the BIOS chip labeled Winbond 25Q256JVEN. Altogether I think I found 4 different firmware chips in the laptop. The BIOS chip is a WSON8 6x8. I used the CH341A, NeoProgrammer, and a cheap pogo pin clip... -
