Hitachi SA200 Manuale Utente

Resume to Full Power mode may fail under the following conditions:

•

The battery is low

•

The size of system memory has been changed

•

The hard disk has been changed

If the system cannot be restored to Full Power mode for any reason, 
a long warning beep sounds and this message displays:

Press any key and run the Suspend to Disk program again to create 
a Suspend to Disk partition.  See Appendix C.

In addition to the power-saving features built into your laptop’s 
BIOS Setup program, the SA200 also supports the Intel-Microsoft 
Advanced Power Management (APM) Interface, version 1.2. This 
is a cooperative interface that enhances your laptop’s built-in 
power management features by providing one of the most accurate 
schemes for detecting true system idle. This scheme allows APM 
to put the CPU into a lower power state with no loss in laptop 
performance.

If you have APM installed on your laptop, you must enable the 
power management feature (set the PM control field to Enabled) in 
the BIOS Setup program. If you disable power management in the 
BIOS Setup program (set the PM control field to Disabled), you 
also disable APM regardless of its settings. When you enable the 
APM interface, APM will override any power management 
settings you may have made in the BIOS Setup program.

When properly installed and configured, APM:

•

Takes over power management from the system BIOS.

•

Constantly monitors all system activity, including the 
operating system, active programs, and the power 
consumption of all devices.
