Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
I am not an expert, just in case, but try to restore the original bios from backup and start from there again. It might have been an error in backing up the bios.
Not the last, you have to get a confirmation message that the patching is done successfully and without any errors. (it happen in my case, so when I flashed the patched bios I could not boot either, so i had to start from the beginning).
Also step 4 - I am not sure that you have to do it, i just wrote the patched bios on the top of original bios. And dont forget you have to write the bios couple of times, so clearing the bios chip is not really necessary in my opinion ( I might be wrong though).
And try to do it from a GNU/Linux system. I think its more straightforward and easy. In Windows you might need to search and install additional software and drivers.Last edited by m3tauser; 12-12-2020, 05:59 AM.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hi
Can someone help me with the patched file from my t470s with SV password. Please find the bios dump attached.
When I flash the patched file I created, the screen stays blank and plays a tone. I was able to flash this original dump back and get the laptop working again.
ThanksLast edited by SMDFlea; 03-25-2023, 11:57 AM.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
@omruu9
Get yourself an EC/KBC programmer and prepare to read firmware, erase it and then program the EC/KBC. You may need to disconnect power supply after you program EC/KBC as it seems the data is retained in memory and may seems as the password is still there (but just in ec/kbc memory). When you erase the firmware it also erases the Supervisor Password, dmi and other data, then use Lenovo utility to type computer model number, serial and other data.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...
