Enabling/Disabling Hibernation
Hibernation is automatically enabled when you first set up your
computer. It is recommended that you enable Hibernation at all
times to safeguard against possible data-loss in a critical low
battery condition. In order for Hibernation to work, it must
allocate space on your hard drive equal to the amount of random
access memory (RAM) installed. To free up disk space, you can
disable Hibernation.
To disable or enable Hibernation in Windows 95, select Start Å
Settings Å Control Panel Å PowerÅ Hibernation tab Å off/on.
NOTE: If you are using Windows NT 4.0, select Compaq Power
instead of Power. If you are using Windows 98, select Power
Management.
If you upgrade memory, the computer increases the Hibernation
file size to accommodate the additional RAM. When the
Hibernation file increases, it requires more hard disk space.
Exiting Hibernation
Select one of the following methods:
■ If Hibernation was user-initiated or a low battery condition has
been resolved, slide the power switch to turn on the computer.
■ If the computer is in a critical low battery condition, insert a
fully charged battery pack or connect an external power
source.
The computer exits Hibernation. The information saved to the
hard disk returns to the screen at the point where Hibernation was
initiated.
Timeout
A timeout is a specified period of inactivity for the computer or its
components. After this time period passes, power management
shuts down the computer or its components to save battery power.
For example, the hard drive component and default timeout is two
minutes. Therefore, if a software application does not access
information on the hard disk for two minutes, the hard drive spins
down until it is accessed again.
