Set a bios password then try to disable it. If that doesn`t work patch it using the Autopatcher or use a pre-patched bios https://www.badcaps.net/forum/troubl...ection?t=81573

hi, I bought a lenovo x270 with of course a bios code, the chip is a winbond 25Q128JVSQ(1736)
I took a CH341a to try to save this story, I tried with the Neoprogrammer which found me chips but I'm not sure of the results,
maybe someone could look I didn't like killing it ^^
thanks

Hello.
I could really use some help unlocking this Bios password for my Lenovo x270.
I attempted to use the autopatch, however I was not able to run the command (obviously I'm doing something wrong) and I've tried using a pre-patched version which gave a blank screen.
Bios is attached.

Serial no: PC-0RE4MJ
Type: 20K5

Ignore my above post. I managed to run the script and unlock the bios!

I extracted the bios of my new (refurbished) Lenovo X270 because the bios is locked and prevents me from reinstalling (I can't boot from an usb key).

You can find the bios attached. Can you please help me unlocking it?

I'm not sure what is the meaning of this post. I can't see what post you are linking...

I tried to use the bios autopatcher, but I can't manage to make it run as the binary is for 64 bits, and my current computer is 32 bits.

[aladodo]

I finally downloaded the lenovo-patcher in order to patch the extracted bios. I manage to get it right and to remove the supervisor password.

Fortunately, I found a 64 bits system in order to run the lenovo-patcher, as my main computer is a 32 bits processor.

Thanks for this tweak!

Hello,

my x270 suddenly got bricked for no apparent reason. When I press the power button the keyboard and the button light up for a few seconds and then turn off again. I've tried the usual fixes like draining the CMOS battery and so on. I've now used a CH341a to back up the bios and flash all other ones I could find, to no avail. The furthest I got with some is that it would beep at the end in addition to what it did before. Can anyone help me?

I don't know how helpful this will be but this is what I was able to find out about it:
TYPE 20K5-S0B700 S/N: PC - 0SURKD 18/02
BIOS chip: W25Q128JVSQ 1740

Thanks in advance.

Then you have no problem with bios let's move on to checking the hardware.
