Preventive Maintenance
This section contains general preventive maintenance information for cleaning the system, LCD,
and keyboard.
Unplug the AC adapter and remove the battery pack before performing
maintenance. Voltage is present inside the system unit and LCD even after the system is turned
off.
Cleaning the Exterior
Clean the exterior of the system as follows.
1.
Power off the system, unplug all cables and peripherals connected to the system, and
remove the battery pack.
Never use harsh solutions, household cleaners, or spray cleaners that
contain caustic materials. These cleaners are usually high in alkalinity which can cause the
plastic surface to crack or discolor.
2.
Wipe the outside of the system with a slightly damp, almost dry soft, clean cloth. Never use
solvents or strong, abrasive cleaners on any part of the system.
3.
Clean the LCD screen with a soft lint-free cloth or a screen wipe designed for that purpose.
4.
Clean the keyboard with a slightly damp, almost dry soft, clean cloth. If necessary, use a
small, soft-bristle brush to clean between the keys.
5.
Periodically use a head-cleaning diskette in the 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).
Cleaning the Interior
Clean the interior of the system as follows.
1.
Remove the top cover and keyboard (see Chapter 3, “Disassembly and Reassembly” for
procedures).
2.
Dust or use a vacuum specifically designed for computer use (with a rubber-tipped nozzle)
to clean inside the system, particularly the main board surface. Use care to avoid damaging
or dislodging any components or cables.
3.
Inspect all cables connectors for damage. Ensure that connectors are seated properly before
replacing the cover.
Protecting the Hard Disk Drive
To protect the hard drive and data, back up the drive periodically on diskettes, Zip discs,
CD-RW discs, or a network drive.
Here are some maintenance procedures to use when servicing a hard drive:
!
Always back up the data files on the hard drive.
!
Run a virus detecting program to check for possible virus infected areas on the hard drive.
!
Use the preinstalled ScanDisk program to correct any errors found in the directory and File
Allocation Table (FAT). This also frees up space from any unused sectors.
