        Now youve posted the backup i can see its a T490s
        The password is stored in the MEC chip,it can only be removed via JTAG using a special programmer, such as Vertyanov JIG (recommend ths one) ,SVOD 3 or 4 ,RT809H

                                          Lenovo ThinkPad T490s Bios Flash

                                          Hi all,
                                          I recreantly acquired a Lenovo T490s from a house clearance and I have no way of getting the bios password. The laptop seems to work fine apart from the password lock. I've bought myself an EZP 2019+ high speed programmer to try to flash the bios.
                                          Just before I attempt this could anyone please confirm that the item circled is the correct bios and is it ok to flash the bios while the chip is still attached to the board.
