Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hi
seems it does not work with Lenovo y50-70 possibly due to the fact it does not prompt for any code just lock after third attempt with wrong password. Are there any tools for Y50 or tutorial how to "erase" the password from the bios? I have CH341a programmer and bios dump I could also solder/de-solder bios but looking for some tutorial what should be edited.
Any hint/help welcomed - and yes I did searched the forum but found only request for y50 passw unlock and reply with unlocked bios but no hints how I can do it myself to learn sth. :-(Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
OK thx I will try it then.
BTW shortening/connecting SCLK/SI pins (pin 6 & 5) of bios chip (U4) does work so I can enter the bios without the password but then cannot change it, anyway all other settings can be changed and saved :-)
The sequence is: 1. use Lenovo key 2. then choose Enter Bios but before pressing Enter the pins need to be shorten/connected (I've just soldered wired switch for convenience) for a while and then Enter pressed and in this very moment pins should be disconnected.
It needs some patience but worked 3 times in the row :-)Last edited by czeslavFu; 01-06-2023, 11:37 AM.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Can somebody help me with X390 Thinkpad bios.
I think this one had older motherboard because this chip was readable with CH341A.

@Monty83
I believe Autopatcher does not work on Thinkpad X390, as it has the Running BIOS and a Backup BIOS, "Self-Healing" prevents patch from working.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hi guys.
I'm struggling here with my Thinkpad X250.
Can't start after last night (apparently updates).
My BIOS is locked and I don't know how to proceed with autopath.
PORAD shows me that it saves the file, but it doesn't save it anywhere.
Can you please help me unlock my BIOS?
Thank you.Last edited by SMDFlea; 03-26-2023, 12:32 PM.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...
