Never remove the battery pack while the power is on as this may result in
data loss when the system loses power.
Power Management Habits
While operating the TREK 2 on battery power, it is important to develop good
power-saving habits to maximize battery life. Although the TREK 2 provides
automatic power-saving features that can be enabled, you can still improve on
them by keeping power conservation in mind.
Conserve Battery with AC Adapter
The most obvious way to conserve battery power is to avoid using the battery
when there is an available AC power source. The AC Adapter is lightweight and
compact, so it is very convenient to bring along while traveling. By using the AC
adapter as much as possible, you can ensure you will have a charged battery
whenever you really need it.
Suspend/Resume Feature
If you need to temporarily step away from the computer, press the power button
for one second to put the computer into Suspend mode. When you return, just
press the power button for one second to restore the system to the point where
you stopped.
Screen Brightness
The brighter the LCD display screen is, the more power it requires. Avoid setting
the screen brightness level higher than necessary to extend the duration of
battery power.
Power Management Modes
The computer has a number of automatic or adjustable power saving features
which you can use to maximize battery life. You can control some of these
features through the
Power
menu in the Setup program. Refer to ”Chapter Eight -
Troubleshooting” for a detailed description of the BIOS Setup program. The
computer is made up of electronic components, all of which consume electricity to
operate.
Yet, some components consume much more than others. The power
management features are designed to save as much electricity as possible by
putting these components into a low power consumption. These low power modes
are referred to as Standby mode and Suspend mode. Standby mode is also
commonly known as System Sleep mode.
Full Power Mode
The computer operates in Full Power mode when power management is disabled.
When the computer is operating in Full Power Mode, the Power LED remains on.
