6-2 Preventive Maintenance
This chapter contains general information for cleaning and checking the PowerMate eco
microdesktop computer.
The LCD/base units, keyboard, and mouse require cleaning and checking at least once a year,
more often if they are used in a dusty environment. No other scheduled maintenance is required.
Unplug all power cords before performing any maintenance. Voltage is
present inside the system even after the power is off. All voltage is removed only when the power
cord is unplugged.
System Cleaning
Use the following procedure for cleaning the system.
1.
Power off the system and unplug the AC adapter power cable.
2.
Wipe the outside of the system, keyboard, mouse, and LCD panel with a soft, clean cloth.
Remove stains with a mild detergent. Do not use solvents or strong, abrasive cleaners on
any part of the system.
3.
Clean the LCD panel screen with a commercial monitor screen cleaning kit. As an
alternative, use a glass cleaner, then wipe with a clean lint-free cloth.
4. Periodically use a head-cleaning diskette in the optional external USB diskette drive to
prolong the life of the drive and to help maintain data integrity. Do not use abrasive head
cleaning kits (kits without cleaning solution).
Local distributors and dealers sell diskette drive head cleaning kits. These kits contain
special diskettes and cleaning solution.
Insert the diskette immediately after powering on the system and before disk bootup. Allow
the diskette drive heads to clean for about 30 seconds.
Keyboard Cleaning
Inspect and clean the keyboard as follows.
1. Power off the system and unplug the AC adapter power cable from its power source.
2. Clean the outside of the keyboard and keys with a damp cloth. Do not use any liquid
cleaners on the keyboard as they can damage the keyboard.
3. Periodically clean the keys with a vacuum cleaner specifically designed for use with
computer equipment. Use a brush attachment designed for use on computers.
Note
The keyboard and cable together are considered a whole-unit, field-replaceable
assembly. Therefore, disassembly of the keyboard is necessary only when cleaning the inside
and then only if the keyboard can be disassembled.
4. As appropriate, clean the inside of the keyboard as follows.
If the keyboard can be disassembled, turn it over, remove the screws (or undo tabs)
holding the two halves together, and separate the halves.
Clean the enclosure and keys with a damp cloth. Use a small, soft-bristle brush to clean
between the keys.
