I am trying to enable my hibernation mode when I run the command powercfg.exe /hibernate on I receive

Hibernation failed with the following error: The request is not supported.

The following items are preventing hibernation on this system.

There are one or more legacy drivers installed:

VgaSave

An internal system component has disabled hibernation.
