ThinkPad P52 NM-B562

for someone who need information
32 mb bios you must read write mec1653. 1 resistor switch 4 jumper wire.

How can you read and write MEC1653? Where is the JTAG ports? I have T580 LTS-2 17812-1 board and cannot find the JTAG to work with the MEC

it can be done with autopatcher and replacing EfiSystem volume with one extracted from bios update. I did few in this way, the problem I encountered was bios chipset, if it is MX25L256 replace with W25Q256 - I don't know why MX chipsets does not work with patched file. So, when I see there is an MX chipset I jut read it and I use a winbond chipset for patched file and and after unlocking I put back MX chipset untouched.

Re: need remove password lenovo p52

read again original bios chipset. I think you read it with errors 1st time.

U mean use original bios, turn on laptop etc. and after that read chip again and try patch it again ??

try this clean ME patched bios.

On this bios still the same issue but i saw 4 restarts not 2 like before. I checked beep code and it says:

0285 - TCG-compliant functionality-related error (might be the TPM initialization failure)
