Power options select under what conditions the pc will sleep. Review them to keep from going to sleep in the first place.
But.. if you set up the pc to sleep to ram(S3 state) sleepand wake will take only a second or two.
The contents of ram will not be saved, so if there is a power failure, the contents will need to be refreshed.
This is a good way to save power when the pc will not be used for a while, and yet allow very fast wakeup.
