Hello friends, I need help with the bios, it's a Lenovo T14 gen1. My bios was locked and I followed the steps from instruction #38, and I got an error (picture attached "error") and after that error the laptop just shuts down. I could get into the boot menu but not run anything from it. Then I took off the bios chip and put it in the EZP2019 programmer and put in a new bios but I didn't succeed, the light from the power button just blinked a couple of times and it just turned off. I managed to save the original bios, but I don't think it's good. Please help me.

someone played with ec, the data is corrupted,
no solutions via bios chip.
you must read ec

the information is false post #38.

NEVER SAVE WITH F10 !!!!!!!!!!!!
just Ctrl alt del after blank password twice
and you must check the information written on the first page before attempting to erase the password.


secondly.it's not 8 and 10 to ground .
it's 8 or 10 to gnd.
you can even use 4 or 6 too

Hi everyone, can anyone upload a photo of the BIOS chip for:
Lenovo T14 Gen1,
serial number: PF-2ZQCB2
TYPE 20S1-S1UJ00

I already have a CH341A programmer with an SOIC8/SOP8 clip. This means I want to read the BIOS and remove the supervisor password.
It would be even easier if this could be done via these jumpers (J9301). Please provide a photo and indicate which pin needs to be connected to ground.

Thanks for your support.
