    Supervisor password on Lenovo T490 and T490s

    Hy everyone, my first thread. Has anyone succeeded in removing SVP stored in the MEC1663 chip in the T490 and T490s? I have a MEC Progammer but I don't know where to connect the wires. Also I undertand that if you erase the eeprom portion of the chip the serial number, mac address and other information are lost. One other forums someone said that if you solder a new chip the bios writes in it what it has too and the laptop works. I don't really want to begin soldering new BGA chips and destroying the laptop.
Working...
