27.0 Power Management

Power management is especially important on laptop computers, but is also useful on other systems. Two technologies are available: APM (advanced power management) and ACPI (advanced configuration and power interface). In addition to these, it is also possible to control CPU frequency scaling to save power or decrease noise. These options can be configured manually or using a special YaST module.

Unlike APM, which was previously used on laptops for power management only, the hardware information and configuration tool ACPI is available on all modern computers (laptops, desktops, and servers). All power management technologies require suitable hardware and BIOS routines. Most laptops and many modern desktops and servers meet these requirements.

APM had been used in many older computers. Because APM largely consists of a function set implemented in the BIOS, the level of APM support may vary depending on the hardware. This is even more true of ACPI, which is even more complex. For this reason, it is virtually impossible to recommend one over the other. Simply test the various procedures on your hardware then select the technology that is best supported.

IMPORTANT: Power Management for AMD64 Processors

AMD64 processors with a 64-bit kernel only support ACPI.
