4-2 Field Service Guidelines
Cleaning the Notebook’s Interior
When servicing the inside of the notebook to remove dust and other foreign particles pro-
ceed as follows:
1.
Remove the top cover, hinge covers, status bar, and keyboard using the disas-
sembly procedures discussed later.
2.
Dust or vacuum (with a rubber-tipped nozzle) the inside of the system unit, par-
ticularly the system board surface. Use care to avoid damaging or dislodging any
components or cables.
3.
Inspect all cable connectors for damage. Ensure that all connectors are seated
properly before replacing the cover.
Protecting the Disk Drives
To protect the disk drives and data, we recommend that you back up the system disk peri-
odically on diskettes. Occasionally use a head-cleaning diskette in the diskette drive to pro-
long the life of the drive and to help maintain data integrity.
Here are some preventive maintenance tips that we recommend you use when handling the
hard disk:
Periodically back up the data files from the hard disk.
Run a virus detection program to identify possible viruses on the hard disk.
Use SCANDISK to correct any errors found in the directory and File Allocation
Table (FAT). This will also free up space from any unused sectors.
Never turn the computer off when the hard disk is being accessed.
Never move or raise the computer while the hard disk is being accessed, impor-
tantly don't jar the hard disk, as this may cause a hard disk crash.
Use hard disk maintenance programs like DEFRAG under DOS or Norton Utili-
ties SPEEDISK to reorganize your hard disk by eliminating fragmentation and
improving hard disk access time.
Handling the Computer Battery Packs
The battery packs furnished with the computer require reasonable care and handling to en-
sure efficient operation and maximum life. Periodically inspect the battery terminals and the
batteries for evidence of corrosion and/or oxide build-up.
To ensure that the battery packs endure a normal life cycle, always observe the following
precautions when handling the battery packs:
