Here is a solution My brother in law got from Dell two weeks ago to the same
problem using USB keyboard and mouse.
Shutdown your computer.
UnPlug the power cable from the computer.
Push and hold down the power switch on the computer for about 30 seconds.
Plug the computer back in and turn it on.
Please let me know if this works for you and if yes what make/model computer
