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 floppy disk-
ettes. Periodically use a head-cleaning diskette in the floppy diskette 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:
■
Always back up the data files from the hard disk.
■
Run a virus detecting program for possible virus infested area 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, most es-
pecially 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 programs. These programs reorganize your hard disk by eliminat-
ing fragmentation and improves the hard disk access time.
