Power-on Self Test Chapter Two - System Features
40
The TREK 2’s hard disk head is self-parking. This means that the TREK 2 can be
directly turned off from the DOS prompt. Close the LCD panel and check that it is
latched securely to the computer. Make sure the floppy drive does not contain a
diskette. When a diskette is inserted in the floppy drive the Eject button pops out.
If you attempt to transport the TREK 2 with a diskette in the drive, you risk
damaging the Eject button.
The computer has an optional soft carrying case. It will keep out dirt and dust and
protect your TREK 2’s casing from becoming scratched or cracked.
If you intend to use battery power, be sure to fully charge the battery pack and any
spares. Remember the adapter charges the battery pack as long as it is plugged
into the computer and an AC power source.
Traveling with the TREK 2
For safety, security, and convenience when traveling with your computer, follow
these guidelines:
•
Before traveling, save your data by backing it up onto floppy diskettes.
•
Take along an extra backup copy of your data.
•
Do not travel with a diskette in the floppy disk drive.
•
Do not transport the TREK 2 with the power on. This may result in loss of
data and/or damage to the hard disk drive.
•
Before traveling, disconnect the AC adapter from the computer.
•
Always carry either a spare fully charged battery pack or the AC adapter.
•
When carrying the computer, take care not to bump it into things. The
computer cannot take the kind of treatment that you might give a briefcase.
•
Whenever possible, hand-carry the computer in its carrying case.
•
If you must ship your computer as freight or baggage, pack it carefully. Use
the original cartons and foam cushions, if possible. If they are not available,
use sturdy cartons and cushion the computer well on all sides.

POST checks memory, the main system board, the display, the keyboard, the disk
drives, and other installed options.
A few seconds after you turn on your computer, a copyright message appears on
your display screen. A memory test message will appear next. The test continues
