The

tab allows you to select the power-saving settings you want to use.
Default settings are shown in red.
Hibernate
Use the
Hibernate
tab to enable hibernate support, see the amount of free disk space, and the amount of
disk space required to hibernate. When your system hibernates it performs a save-to-disk or save-to-file
(STF). Your current working environment is saved to the hard disk. Use the Power button to resume from
hibernation and your system returns to its previous state.
Windows XP Power Management States
The Advanced Configuration and Power Interface (ACPI) uses different levels or states of power
management. These power management states occur automatically, based on the system
’
s default settings,
or manually, when invoked.
The Windows XP ACPI power management states include:
Monitor timeout
- manages power at the lowest level by shutting down the monitor.
Standby
- also known as Save-to-RAM (STR), Standby manages power by saving your current
working environment to memory and shutting down most system devices.
Hibernation
- also known as Save-To-Disk, or Save-To-File (STF), Hibernation manages power by
saving the current working environment to an area on your hard disk before turning off your computer.
When you restart the computer, any programs and documents that were open when you turned the
computer off are restored on the Desktop.
Recognising the Power Management States
It is important to recognise your system
’
s behaviour when in each of these power management states. The
