Lenovo Thinkpad E15 gen2 GE4B0/GE5B0 NM-D011

[igragon08]

Hi everyone!
I left my Lenovo E15 Gen 2 plugged into an AC charger overnight, updating Windows. When I picked it up for work the next morning, it turned out it had stopped working via AC power. It can't charge via the charger (it only runs on battery power). I've seen the same thing happen to a colleague here: the AC power doesn't work (when I plug in the charger, the power button blinks several times but doesn't actually work on AC power), and the battery is low (when it runs out, I won't be able to turn on the PC unless I plug in another, equally charged battery). I thought it might be a problem with the updates overnight or a problem with the BIOS chip. It also has a supervisor password. I'm sending you the image of the readings made on my WINDBOND 25R256JVED BIOS chip, as well as all the data on my PC. In case, with any luck, it's a BIOS problem and one of you can fix it, I'd be very grateful!

hi,

I have following laptop with BIOS locked with password:

Board Number: GE4B0/GE5B0 NM-D011 rev 1.0
Serial Number: PF-2JKBXT
Type Number: 20TA-000DUK

I've used T48 to read bios chips but I could not find the W25R256JVWQ in the list, so I've read content as W25R256JV, hope is no issue

Thanks in advance

This is the original BIOS and the machine boots up with it, but there is no MAC address and ME version. When trying to update from USB, it reboots without updating.

Hello everyone,
Lenovo Thinkpad E14 gen2
Board GE4B0/GE5B0 NM-D011 rev 1.0
SN PF2HRFX9
maybe someone can help me.
After numerous attempts to program with different versions of T8227E-256 and 25R256JVEQ, I got a stable result, the laptop turns on, the processor heats up, the cooler turns on, but there is no image
I am 100% sure that my problem is in the wrong BIOS
Perhaps the 256 KB dump is also faulty
My old BIOS is 256 Kb and 32768 KB
Thanks
