Lenovo ThinkPad L13 20R3 EC / BIOS

[REpairAT]

Hi,
got this device turning off after a second after switching on, no shorts, after CMOS Reset it sometimes lasts for 10 seconds but turns off then. Voltages general 20V and 3.3 on EC constantly present. I assume there's a problem with the EC FW.

Dumped the EC, it's almost blank (Attached).

Could anyone upload a working dump of BIOS and EC?

Thanks!

Serial number's not correct, but let's try with this bios ( i can't find EC file ).

If still same problem, clear ME your bios file and reflash.

After updating the BIOS via the Lenovo Windows app (official website), my laptop no longer boots up. Can anyone help me?
