Lenovo Thinkpad E14 (20RA) clean ME

[garfild]

Hello guys,
I got non functional Thinkpad E14
type: 20RA-001EMC
MB: NM-C421 REV 1.0
Latop reacted just to ram removal, thanks to the fixed dump in different thread I am able to very slowly (3 reboots) 0183 CRC error, which I consider as success!

attached is dump from my version, kindly asking for clearing ME and if possible, also BIOS password removal.

thanks a lot!

Try this one. If the warnings are still there then post your EC backup

Hello sir,
thank you very much, unfortunately this fix does not work. After the dozen of the minutes it reached error screen, now Iam not able to replicate errors. Esc LED is on, which is better sign.

As far as I understood there is no separated eeprom for the EC.

there is 1 chip only which should contains bios and EC

schematic shows 2 SPI roms but on the board there is just 1 roms chip

or did I miss something?

thanks a lot!
