Preventive Maintenance
This section contains general preventive maintenance information for cleaning the notebook
case, LCD, and keyboard.
Unplug the AC adapter and remove the secondary battery (or optional
battery, if installed) before performing maintenance. Voltage is present inside the notebook and
LCD even after it is turned off.
Cleaning the Exterior
Clean the exterior of the notebook as follows.
1.
Power off the notebook, unplug all cables and peripherals connected to the notebook, and
remove the secondary battery (or optional battery, if installed).
Never use harsh solutions, household cleaners, or spray cleaners that
contain caustic materials. These cleaners are usually high in alkalinity which can cause the
notebook case to crack or discolor.
2.
Wipe the outside of the notebook with a slightly damp, almost dry soft, clean cloth. Never
use solvents or strong, abrasive cleaners on any part of the notebook.
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 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).
Cleaning the Interior
Clean the interior of the notebook as follows.
1.
Remove the front cover and VersaGlide™ assembly, keyboard, and top cover to access the
interior of the notebook (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 notebook, 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 removed assemblies.
Protecting the Hard Drive
To protect the hard drive and data, back up the drive periodically on diskettes, CD-RW discs, or
a network drive.
Here are some tips to use when servicing a hard drive:
!
Do not squeeze the top and bottom of the hard drive or the drive might be damaged.
!
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.
