Hi,

I found the W25Q256JVEQ Bios chip. It is a 8-WDFN Exposed Pad type chip. How do I connect to it and read it?

Sorry for the newbie questions. I never came across one of these chips.

ThinkPad X1 Carbon Gen 7, type 20QD, S/N PF-21V10Z

The notebook starts & lights up, but screen is blank (although I tested it works), no POST.

Maybe ME clean required?

Thank you for your help.

In my previous post I attached the uncompressed bios dump (i.e. it's not a zip file). Sorry about that.

use Lenovo maintenance utility to write DMI in EC. You'll find B0 to a label from motherboard (8S....) , C0 is 1S20QD000LUSPF14N29Q and brand name is ThinkPad X1 Carbon Gen 7

The device information still matches, I used that utility to delete and rewrite it but it didn't work, I loaded another bios and the notification went away but the update was very slow but I tried clearing me but the power didn't work.

Oh,, luckily I managed to clean the bios

Resetting no success.
Now i took out the bios chip (25Q256JVEQ) and read the bios in the RT809F ISP Programmer (?correct?).

THX hoaca388, the provided BIOS.BIN worked perfectly.
had to perform several attempts to flash the BIOS.BIN to bios-chip (RT908f Programmer).
Can further use the Laptop.
