9.3 Configuring Power Management
KDE 4 lets you adjust a number of power management settings: for example, when to
trigger notifications or warnings, which power profile to use when running on battery,
what to do when closing the laptop lid or pressing the power or sleep button.
Access the configuration options from the main menu by selecting Configure Desktop
> Advanced > Power Management. Alternatively, click the battery monitor icon in the
panel and click select Configure.
