when my hp elitebook 8730w sleeps.. and when I go to wake it up the mouse is fine but the keyboard does not respond .. including the numlock... so using the mouse I am able to shutdown restart the laptop.. when it is up again minutes later the keyboard commands work .. but later that day when the PC sleeps or is hibernating or is dark until woke with mouse.. the keyboard again is not working this is the fourth time in the last few hours ..

Ideas ??
