Hello, I have a thinkpad T490 with intel i5 8365U, serial number: PF221WKE, i am trying to remove the supervisor password using a c341A programmer. I have a few question: i need to give power to the thinkpad while i am connected with the programmer?, if yes, i need to plug it to the charger; attach the battery or attach the cmos battery?. i already have installed the driver for the programmer and i have the sotware, but it dosnt recognise the thinkpad but it recognise the programmer. i am probably doing something wrong.pls help
