14.1.1 Power Conservation
The inclusion of energy-optimized system components during laptop manufacturing
contributes to their suitability for use without access to the electrical power grid. Their
contribution towards conservation of power is at least as important as that of the oper-
ating system. SUSE® Linux Enterprise Server supports various methods that influence
the power consumption of a laptop and have varying effects on the operating time under
battery power. The following list is in descending order of contribution towards power
conservation:
• Throttling the CPU speed.
• Switching off the display illumination during pauses.
• Manually adjusting the display illumination.
• Disconnecting unused, hotplug-enabled accessories (USB CD-ROM, external
mouse, unused PCMCIA cards, WLAN, etc.).
• Spinning down the hard disk when idling.
14.1.2 Integration in Changing Operating
Your system needs to adapt to changing operating environments when used for mobile
computing. Many services depend on the environment and the underlying clients must
be reconfigured. SUSE Linux Enterprise Server handles this task for you.
