Wake-on-LAN (WOL) enables computers to be woken from sleep in response to a command arriving from the network. This helps save power because computers can be allowed to sleep after working hours even when computer-management tasks are scheduled that night.  
   
To use WOL, your clients must be fitted with a network card that supports the standard.  
   
You can schedule WOL signals to match other scheduled maintenance tasks, like reinstallation of a computer, or schedule a computer group to perform a WOL on specific times.  
   
See [Schedule groups](/capainstaller/the-capainstaller-console/configuration-management/how-to-use-configuration-management/working-with-groups/schedule-groups/) for more information.  
CapaInstaller also provides features that enable you to send a WOL signal manually to any computer or selection of computers, which is described below.
