h1. EnergySettings

h2. Requirements

To setup energy-settings you will need the following:

* a installed and supported operating system (e.g. Windows 7)

* administrator rights

h2. Preliminary Note

It might not be necessary but it seems that Windows 7 randomly hangs when trying to do some energy-saving on the virtual machine hardware supplied by VirtualBox. This behavior has been especially reported with VirtualBox 4.0.2. As there is no good reason to switch off virtual harddisks and displays anyway, we do it regardless of the VirtualBox Version.

h2. Setup

* open start-menu and select @Control Panel@

* We can't change the details right away, so we choose our new plan @FullThrottle@ and goto @Change plan settings@

* Now we goto @Change advanced power settings@

!{width 500}win7_energy_8.png!

* select @Hard disk / Turn off hard disk after / Setting@ and enter @0@, this will result in @never@

* select @USB settings / USB selective suspend setting / Setting@ and choose @Disabled@

* close the form with @OK@

* for some unknown reason we **don't get** @Save changes@, so we just close the window

h2. 4 Check functionality

reboot the machine and check if the energy plan @FullThrottle@ is active and all settings are as set before
