When to Replace the Battery

Over time, the battery's capacity gradually decreases. We
recommend that you replace your battery when you notice that
it begins to store significantly less charge. See
tion and Removal for more information.

Heat Considerations

The computer's processor has been specially designed to
consume as little power as possible, and generates very little
heat. However, working in a hot environment, or working for
long periods may raise the temperature. The GD6000 takes the
following steps to lower temperature:
1.
The cooling fan turns on automatically. You may feel air coming
from a vent at the left side of the computer when this happens.
2.
If the temperature continues to rise, processor activity will be
reduced. You may notice a slight loss of performance when this
happens.
Warning
If the CPU temperature exceeds 95°C, the system
will shutdown to prevent the heat from damaging the com-
puter's infrastructure. The system will also shutdown if the
Hard Disk Drive gets too hot. When the computer cools to a
normal temperature you can restart the system. The higher the
temperature, the longer the period the computer will need to
cool down.

Monitoring Battery Power

Low Battery Alarms

Caution
When battery power is low, the alarm beeps or
displays a warning on your screen. Take immediate action,
such as saving files or connecting to the AC adapter or data
may be lost.
When the computer alerts you that the battery is low, immedi-
ately do one of the following:
Connect the AC power adapter.
„ „
Save your work and then select
„ „
menu.
Turn off the computer and replace the discharged battery with
a charged battery (see
Battery
note
Do not restart the computer until you have connected
to an AC adapter or replaced the discharged battery with a
charged battery.

Operating with Battery Power
Refer to Battery Tips for more information about how you can
conserve battery power. Refer to
mation about how you can setup your computer to effectively
manage power for your unique use patterns.

Managing Power

Your computer has power management capability so you can
reduce the amount of energy used, especially during periods
of inactivity. Effective use of power management options
can greatly conserve and extend your battery life. The power
management unit monitors system activity, such as hard drive,
keyboard, mouse, or any devices attached to a port. If it does
not detect activity for a period of time, the computer stops
some or all of these devices in order to conserve energy.
Your computer employs a power management scheme that
supports ACPI (Advanced Configuration and Power Interface),
allowing for maximum power conservation and maximum per-
formance at the same time. Windows handles all power-saving
chores for your computer.
For more information search for Power Options in Microsoft ®
Help and Support.

Low-Power States

Your computer can enter three different low-power states to
conserve power: Standby/Sleep, Hibernate and Power Off.
These states can be entered manually, or after a period of
inactivity.
Standby/Sleep
Most devices in the system are powered off, but the contents
of system memory are retained. Standby/Sleep is sometimes
referred to as Suspend to RAM. When the computer returns
from standby mode, the desktop appears with the same files
and programs open as when the computer was suspended.
Resume time is very quick.
Hibernate
Hibernate, or Suspend to Disk, is similar to Standby, except
that the current state of the computer is copied to the hard disk
in a special file. After this occurs, 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.
Power Off
All applications are closed and the system is shutdown.
