Mobile Computing
Working on a mobile computer requires a great deal of flexibility in adjusting to
changing network and system environments. SUSE LINUX offers small helpers,
like GNOME Battery Charge Monitor, KPowersave, and Profile Chooser, which
assist you in adjusting the power management scheme and the system configura-
tion of your computer.

Power Management
Successfully working on battery power requires a very sophisticated handling
of the system resources by the operating system. Mobile hardware is optimized
to allow a very flexible management of power usage by the CPU and other com-
ponents. Depending on the environment in which the system is run, the power
management can easily be adjusted in SUSE LINUX using GNOME Battery
Charge Monitor or KDE KPowersave.

management can easily be adjusted in SUSE LINUX using GNOME Battery
Charge Monitor or KDE KPowersave.
Battery Charge Monitor allows you to send your machine into a hibernation state
(‘Suspend Computer’) in which the entire system state is written to disk prior to
shutdown. Once reactivated, this state is recovered. Configure the power man-
agement settings via ‘Power Management Settings’. The YaST Power Manage-
ment module is launched enabling you to configure all power management set-
tings centrally.

Using KPowersave, you can start the YaST Power Management module and is-
sue both a suspend to disk or a suspend to RAM (if configured accordingly with
YaST). You may change the CPU frequency policy, meaning your system either
lets the CPU frequency drop when the system is idle and adjusts it dynamically
if more CPU power is needed (set the CPU frequency policy to ‘Dynamic’), per-
manently keeps a low CPU frequency to save power (select ‘Powersave’ ), or per-
manently keeps a high CPU frequency for maximum CPU performance (select
‘Performance’). If you change the active power management scheme (‘Set Active
