RE: DRIVER POWER STATE FAILURE on My Dell Vostro 5459

I am sorry to read that you are having this problem.  Did the notebook ship with Windows 8.1 or Windows 10.  If the system shipped with Windows 10 do you remember the problem then or is this something that only noticed after installing windows 8.1

The reason why I ask is that Driver Power State Failure messages usually indicate a missing or incorrect driver. 

If you haven't tried it yet, you can go here and run a scan to detect needed drivers.
