Standby mode
This page is still under construction, it is meant to be added to the glossary
The standby mode is one of three power-saving modes for the Thinkpads. In this mode, only the LCD screen (and the external monitor, if attached) is turned off in order to save power. You can enter this mode by pressing Fn+F3 or by configuring your computer to enter standby mode automatically after a chosen duration of inactivity.
