Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hello all! I have registered just to say thanks so much for this thread and I appreciate the hard work that has gone into it.
I am posting because I have an old ex-corporate Lenovo X1 Yoga (First Generation made about 2015) which the company forgot to remove the supervisor password from when I got it. This has long, long annoyed me but I had to live with it!
Recently I wanted to use VM and couldn't because it's locked. Grrr! So I have decided to fix the issue. I've read many pages of the thread (not all...) and researched the steps in detail.
This is what I plan to do - any obvious mistakes?
- Step 1: Buy a CH341a mini programmer with clip from Amazon. Open my laptop up (have done this before so no problem). Use the CH341a to read the bios chip (I found instructions for the X1 Yoga here which suggests this works specifically for the X1 Yoga: https://www.youtube.com/watch?v=r8f-3syiFSc)
- Step 2: Patch the bios using the amazing tool uploaded in this thread.
- Step 3: Upload the bios using the CH341a and get rid of the annoying supervisor password and be freeee!
I will back up the laptop before doing any of this (it's my primary device, working fine with no restrictions apart from the bios supervisor password and don't want to lose any data).
Key concerns: is the CH341a the best tool for the job, or are there better devices? Will this work for the Lenovo X1 Yoga Gen 1? Odds of bricking my device?
Thanks again

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
I have an e475 (one of the AMD apu Thinkpads). The auto-patched bios took a new password, gave the ok arrow, and then went to a permanent a blank screen (no option to enter hardware id and then hit spacebar). Would appreciate any suggestions. Attached are the original and patched bios.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Your backup is only 103.9 KB ,you havn`t made a good backup. Besides that, why isn`t the Autopatcher working for you ? ,if you can get it working you can patch the bios yourself, once youve made a proper backup.Do you have python installed, are there any error messages etc, whats the problem.
Also post the full model number when you ask for help

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)

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... -
