Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
@Linux200
I suggest to read the instructions in post #1 of this thread, with the patched bios you will have to power-on the laptop and after it shows LENOVO splash screen, immediately press appropriate key to go into Setup/BIOS (press F1 key). Then follow the instructions.
If the laptop does not respond to F1 key press, then most likely it does not have a Supervisor Password set, but you can use a locked hard drive to make the patched file to work and to deactivate CompuTrace (if active).Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hi,
I have an Lenovo ThinkPad Yoga 260 and is password locked to bios.
I did repair this laptop after it had a failed coil.
With this model can I just reprogram the bios chip or does it require special software to remove the password? so I can boot the laptop and verify all conditions are fully working.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hi All
I've read through the entire thread and researched other web pages and given this a go. Unfortunately when I try and boot after writing the patched bios nothing happens. Laptop won't turn on at all. I've tried disconnecting batteries (CMOS and main) nothing.
I've tried to write the original dump back to the chip, nothing
I've obviously done something wrong. Any advice?
Lenovo Yoga 260. Original Dump attached.
I've used CH321A with AsProgrammer
Any advice gratefully received. CheersLast edited by SMDFlea; 03-25-2023, 11:57 AM.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hi, thanks for your help. I've tried writing that to the chip. Once written I've tried to verify and get the following
Verify memory...
Verification error on address: 00000019
Execution time: 00:00:00
Laptop still won't respond when I tried to boot. No beeps, no lights, nothing.
I think I may have broken something but not sure what. Could it be the bios chip is fried?
Not sure where I've gone wrong. I dumped the original 3 times and compared them, they're all fine.
I've successfully patched the original.
I've tried programming the chip with the patched bios, the original bios, other patched bios's from this forum but I get nothing...Comment

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,... -
Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V.... -
Hi everyone,
I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.
I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.
After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.
I have desoldered the bios chip (GigaDevice...
