Thinkpad E15 Gen 4 AMD NM-E501 bios

[trepachka]

Hello, I have a Thinkpad E15 Gen 4 laptop. It appears to be starting as I can hear the fan spin and the cpu gets properly hot. However, no video and no keyboard action on start

I suspect corrupted BIOS. Please, someone help me clean the BIOS image. Thank you

Hey, I applied the new BIOS. I can clearly see progress. Before the keyboard stayed dark. After applying the new BIOS, "Esc", "Caps Lock", "F1" and "F4" keys now briefly flash which is what I was expecting.

They are supposed to flash 2 more times before getting the image on the screen but that didn't happen.

Can you see whether you can make additional changes to the BIOS?

No, your hardware is still not stable.

The bios file you provided did make changes in the computer's behavior. As I mentioned before the changes, no keyboard lights. After the reflashing of the bios, computer attempts to boot with several keyboards keys flashing.

Try.

Upon reflashing the bios with the new bin, I am now getting a brief screen flash as well as those 4 keys briefly lighting up. Then, nothing. Computer is now drawing a little more amperage, around 0.64 vs. 0.59 before

Are you sure from this Serial Number?

hi try

I tried this new BIOS file and I am still getting the same response from the computer. I suspect RAM could be faulty. The 4th gen of Thinkpad E14/15 comes with soldered 8GB of RAM for both Intel and AMD processors
