If this operation is possible, I would send back all result's data as soon as I relay the modded-bios file to T420 owner and explain procedure of flashing original bios with modded one..
People usually afraid to do bios upgrades around me, so I m persuading them to go free passing this forum knowledge to them

THANKS MUCH,
