Audio System
The TREK 2’s audio system includes a sophisticated built-in ESS PCI stereo
audio-sound generator compatible with Sound Blaster and Microsoft Sound
System. The sound system includes amplified output, two built-in 1 watt stereo
speakers, manual volume control, and built-in microphone.
Audio Ports
The TREK 2 comes with four audio jacks: a line in for connecting audio equipment
for use with the multimedia system; and a line out for connecting stereo speakers,
a headphones jack, and a microphone jack.
Audio Volume Control
The TREK 2 is equipped with hot-key volume controls: Pressing the [Fn] + [F3]
hot-key combination decreases the audio output volume. Pressing the [Fn] + [F4]
hot-key combination increases the volume.
Battery and AC Power System
The TREK 2 can operate on two power sources; an AC adapter, or the
rechargeable battery module pack.
The AC adapter has automatic 100-240V line switching, which will automatically
check the power voltage coming out of the wall and adjust it to the voltage your
computer requires.
The system will automatically recharge the battery pack in the TREK 2 by using
the AC adapter. By using the power management features described in using the
TREK 2 and BIOS setup chapters, the TREK 2 can operate on battery power for
approximately two to three hours. For extended battery-powered operation,
additional battery modules may be purchased.
Security
The password protection feature of your TREK 2 prevents unauthorized people
from accessing important files and information on your computer.
Input/Output Devices
Most of the TREK 2’s hardware features can be described as input and output
devices. An input device is a hardware device used to enter information to be
processed by the computer. Examples of input devices are the keyboard and the
touch pad. An output device, (LCD display, monitor, or printer) receives data from
the computer and displays the information in a human-readable format.
Other Devices
Other hardware components such as the serial port, parallel port and disk drives
are both input and output devices. They can be used for transferring data to and
from the computer.
