Hibernate
Hibernate, or Suspend to Disk, is similar to Standby except
the current state of the computer is copied to the hard disk in
a special file. Then, all devices in the computer are turned off.
When the computer returns from hibernation, the desktop
appears with the same files and programs open as when the
computer was suspended. Hibernation saves more power than
Standby, but takes slightly longer to resume.

Battery Tips
Tip 1. Avoid excessive heat and cold
Your battery will last longer during the day if it is used, charged
and stored between 50°F and 86°F (10°C and 30°C).
Charge the battery nightly where the temperature will remain
around 68°F (20°C). Your battery may not last as long through
the day if you charge it at higher or lower temperatures.
Allow unrestricted airflow while the computer is connected
to external power. Make sure that the fan inlet and outlet are
unobstructed.
Avoid exposure to extreme temperatures for long periods as this
can shorten battery charge life or damage the battery.
How your battery behaves in warm conditions
To prevent possible battery damage, the system may not allow a
charge if the battery temperature is above 122°F (50°C), such as
in a closed, unattended vehicle during the summer. In this case,

not be fully charged.
If possible, turn off or suspend your computer while the battery
is charging in a warm environment to avoid over-heating.
In warmer temperatures, your battery may take much longer to
fully charge.
How your battery behaves in cold conditions
When using a battery in cold conditions, the battery capacity
may drain significantly faster than normal.
To prevent possible battery damage, the system will not allow a
charge if the battery temperature is below 41°F (5°C), such as in
a closed, unattended vehicle during the winter. In this case, the

Use the AC adapter or vehicle adapter whenever possible.
To help save power, use the DynaPower utility.
When running on battery power, make sure your system
suspends automatically after a few minutes of inactivity. PC
Cards, radios, custom applications, or modified system settings
may affect battery power.
Remove PC Cards and unplug peripherals when you are not
using them. They may draw power from the system even when
not in use.
Avoid operating the fax/modem, or audio and video applications
when using battery power. Operating a fax/modem, video, or
audio equipment increases the computer's power requirements.
Don't use screen savers as they draw excessive current,
especially "3D" screen savers.
Turn off the Wireless LAN when not using it. Turning on the
Wireless LAN increases the computer's power requirements.
Avoid or minimize using applications that keep the CPU busy a
large percentage of the time. The following items will help you
determine if your system is running such applications.
Identifying power wasting programs
To determine if applications or processes are keeping the CPU
busy:
1.
Task Manager

the
tab to view running processes.
3.
Watch the CPU ssage. It is okay if the processor usage is
occasionally 100 percent, but if it is 100 percent most of the
time, this may indicate a problem.
What to do if applications are keeping the CPU busy
If possible, close applications that keep the CPU busy when you
are not using them.
Turn off or suspend your computer whenever you are not using
it. This will help to conserve power.
