4-2 Field Service Guidelines
Cleaning the Notebook’s Interior
When servicing the inside of the notebook, remove dust and other foreign particles from in-
side the system unit as follows.
1.
Remove the top cover and keyboard using the disassembly procedures discussed
later in this section.
2.
Dust or vacuum (with a rubber-tipped nozzle) the inside of the system unit par-
ticularly 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 or
external backup device. Periodically use a head-cleaning diskette in the disk drive to pro-
long the life of the drive and to help maintain data integrity.
Here are some maintenance procedures to use when servicing a hard disk:
Always back up the data files from the hard disk.
Run a virus detecting program to check for possible virus infected areas on the
hard disk.
Use the preinstalled ScanDisk program to correct any errors found in the direc-
tory and File Allocation Table (FAT). This will also free up space from any un-
used 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, most es-
pecially don't jar the hard disk as this may cause a hard disk crash.
Acquire a hard disk maintenance program like DEFRAG under DOS, or Norton
Utilities SPEEDISK programs. These programs reorganize your hard disk by
eliminating fragmentation and improves the hard disk access time.
