Thread update, Dell-Cares set up service for the system.
I have an Alienware 15 R4. I turned off the laptop two days and now I open it, but I cannot type the password on login screen? I used the keyboard on screen, but I also type it. On the keyboard on screen, the key of Shift, Ctrl, and Alt are lighted. I have changed another keyboard (using keyboard connected into USB). I don't know what happened. I press F2 and F12 to reset up and reboot, even though I am able to access into the reset page but I cannot use the keyboard?
15 R4, login screen, cannot enter password?
