Hyper-V Server on a laptop - don't forget to check the power settings for the default power scheme

If you install Hyper-V Server it comes without the usual Windows Server UI. On a laptop this means there is no control panel applet or system tray battery icon available to adjust the power configuration. 

It's highly unlikely that the default option of Balanced is what you really want for hosting virtual machines, and you will ideally to set it to High Performance instead.

No need to worry, you need the command line tool, powercfg. Run the command line with the option list and then use the -setactive option with the long GUID to select your desired power scheme, as shown in the screen grab below. Job done.
