This bios is extracted from .exe file downloaded from Lenovo homepage, maybe your problem is not related to bios.

Lenovo ThinkBook 15 G2 ARE no image after bios update

Hi,

As the title implies,i have a Lenovo ThinkBook 15 G2 ARE with no display after a bios update made by windows trough optional updates.The laptop charges the battery,recognizes the charger (hopefully),starts up but has no image on screen.I have tried rewriting the bios with a few dumps i have found on the forum and outside of it but nothing changes.

So,when i press the power button,the power led,FnLock,CapsLock and NumLock led lights up for 2 seconds then the CapsLock and NumLock turn off and just the Power and FnLock remain on....and nothing happens after that.If i let the laptop stay on for a while,the fan starts spinning as the processor heats up.
I have the 5v 3v3 and other power supplies on for cpu,ram,EC etc.

I suppose it's bios related issue or EC firmware corrupted.I can assume the EC did not update but the bios did and now they are "incompatible".So if there is anyone with an older version of bios to try it i would be glad if someon shared it ....or any suggestion would be great.

I will attach the current bios on the flash,maybe someone can help me out...

Cheers.

Hi, I have a ThinkBook 14 G2 with exactly the same behavior. Already tried to flash a few different BIOS images but no change.

Did you manage to fix it in the mean time?

Cheers

P.S.: Attached the BIOS and the EC(?) dumps

Update: The smaller firmware was for the PD controller. After flashing the EC with a fresh version extracted from the Lenovo Update file... nothing changed.

Can you help me disable the VRAM on this Lenovo? I tried to find a schematic and boardview to disable it by moving the OBRAM_ID resistors, but without those files it's difficult. So, I want to know if you can help me disable the VRAM through the BIOS. Thank you very much in advance. By the way, the BIOS I uploaded is in good condition. It provides video, recognizes SDDs, and logs into Windows normally. The problem with the machine itself is that it displays colored lines when rendering.
