Does this solution work on Lenovo E595?Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
@bojc
Most likely it does, as ThinkPad models ending with "5" have AMD processors, in which the bios firmware does not have the "Self-healing" bios protection.
So it should work for Lenovo ThinkPad E595, just make sure that you have a good bios firmware dump before starting.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hello all,
thanks for the tutorial and the software!
I will try to patch my T450 tomorrow.
However, I still have 2 questions.
1. do I also have to disconnect the internal battery (My Thinkpad has two batterys).
2. do I have to disconnect the CMOS battery or can I leave it on? (Want to flash the chip without unsoldering it).
Thank You!Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Ok thank you. But i have a Problem.
I have the Chip w25q128fv. If i take this dump the patcher gives me follworing error:
Using UEFIReplace to inject 2 DXE drivers...
[1/2] BootOption (GUID e0746c42-d3f9-4f8b-b211-1410957b9ff5)
t450_3.bin is corrupted or does not contain a valid dump.
There was an error... Aborting.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hello,
I am using the TL866 II Plus programmer with a SOP8 clip to read the BIOS chip of my Yoga 460. Although the Xgpro 10.75 software autodetects the BIOS chip correctly as MX25L12835F@SOP8 it stops reading with an ID error. The software returns "Check ID Error! Checked ID is:0x C0 00 08".
When I force it to ignore the ID error and read the chip anyway and try to read the dump in UEFITool it returns "FfsParser::parse: not a single Volume Top File is found, the image may be corrupted."
I guess, my TL866 II Plus programmer can't read the BIOS correctly. Can someone point me in the right direction to get a valid dump of my Y460 BIOS? Do I need a different programmer, software, or adapter for the clip? I hope I can use my TL866 II. I have attached a picture of my programmer setup.
Thank you in advance for your help.Attached FilesPremium supporters get full download access and other benefits.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Thank you very much! It seems I have to order it from China, as I can't find it at any shop here in the UK
. May I ask you for a better picture of the wiring between SPI-Driver and the clip?
Would it work with a CH341a programmer and my clip straight away?
Sorry for asking all these noob questions.
Thank you for your help.Last edited by Babyface_male; 02-01-2021, 03:35 AM.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 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... -
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... -

Hello everyone,
I have a Lenovo IdeaPad Gaming 3 16IAH7. When the device first arrived, there was no display at all.
I had the BIOS cleaned, but the issue was not resolved and there was still no image.
Later, I flashed a different BIOS dump from the same model. With this BIOS, the device boots and display works, but the GPU is not detected in the BIOS (RTX 3060 is missing).
After that, I tried to update the...
