4-2 Field Service Guidelines

Cleaning the Notebook Exterior

Use the steps below to clean the outer surface of the system.
Power off the system and remove all battery packs. Unplug all cables connected
1.
to the system.
2. Wipe the outside of the system, keyboard, and display with a soft, clean cloth.
Remove stains with a damp, almost dry cloth. Use glass cleaner to clean the
LCD. Apply the glass cleaner directly to the cloth and then wipe the LCD. Do not
use solvents or strong, abrasive cleaners on any part of the system.
3. Clean the keys with a damp cloth. A small, soft-bristle brush may be used to
clean between the keys. Make sure to use a damp cloth (not wet) to prevent
moisture from seeping between the keyboard and the metal plate, possibly dam-
aging the components under the keys. If the keyboard gets wet, thoroughly dry it
before reassembling the system unit.

Cleaning the Notebook Interior

When servicing the inside of the notebook, remove dust and other foreign particles from
inside the system unit as follows.
Remove the top cover and keyboard using the disassembly procedures discussed
1.
later in this section.
Dust or vacuum (with a rubber-tipped nozzle) the inside of the system,
2.
particularly the motherboard surface. Use care to avoid damaging or dislodging
any components or cables.
3. Inspect all cables connectors for damage. Ensure that connectors are seated prop-
erly before replacing the cover.

Protecting the Disk Drives

To protect the disk drives and data, back up the system disk periodically on diskettes. Peri-
odically use a head-cleaning diskette in the disk drive to prolong the life of the drive and to
help maintain data integrity.
Here are some maintenance procedures to use when servicing a hard disk:
T
Always back up the data files from the hard disk.
T
Run a virus detecting program to check for possible virus infected areas on the
hard disk.
T
Use the preinstalled ScanDisk program to correct any errors found in the direc-
tory and File Allocation Table (FAT). This also frees up space from any unused
sectors.
