Tips for Computer
Care
Cleaning of outer surfaces of a computer can be done with
soap and water as long as the solution does not enter the
internal parts of the computer. The solution should be applied
with a lint-free cloth. The cleaning should be followed with
an anti-static spray that can be made out of water and fabric
softener. Internal dust can be cleaned with canned air, a
soft brush or anti-static vacuum. Anti-static vacuums are
specially grounded to prevent static discharge like regular
vacuums. Dust can contribute to overheating problems. Making
sure that all expansion slot covers are in place can reduce
dust buildup. Missing covers can also disrupt the airflow
design of the case and cause overheating problems. Additional
fans can be added to help cut down on internal temperature
problems. Computer equipment should not be placed in areas
of extreme temperature or humidity. Oxidation corrosion can
slow down or even prevent electricity from flowing through
contact points. Oxidation buildup can be removed by rubbing
with an emery board or eraser. It can also be cleaned with
special cleaning solution. Other internal components can be
cleaned with Isopropyl alcohol and lint-free swabs. Monitors
should be cleaned with a soap and water solution with the
power disconnected. Do not use household cleaning solutions
as they can damage the screen. Monitors should not be opened
unless you are qualified to work on them. Deadly voltage can
be stored inside the monitor even a year after it has been
turned off.
Computer components should be transported in antistatic foam
or an anti-static bag. Hard drives are vacuum sealed and should
never be opened except by professionals in a "clean room".
Important data should be regularly backed up and stored in
a fire- proof safe or at a separate location for protection
against fire or theft. Windows NT/2000 Emergency Repair Disks
should be stored in a secure place where only authorized personnel
can access them. Because floppy disks are magnetic media,
they should not be exposed to magnetic fields that can be
produced by TVs, monitors, speakers, power supplies and appliances
with motors. Floppy drive heads can be cleaned with a wet
or dry head cleaning disk. Keyboards can tend to collect dust
between the keys. They can be vacuumed with a small vacuum.
Mouse needs to occasionally have the X and Y rollers cleaned
with a lint-free swab. Electrical spikes (measured in nanoseconds)
or surges (measured in milliseconds) can cause damage to system
components or even data loss. Surge suppressors can prevent
minor variances in power and provide a stable stream of electricity
to the unit, however, they may not always work against larger
surges. Uninterruptable Power Supplies (UPS) provide power
to the devices connected to it for a period of time in the
event of power loss or sag for long enough to gracefully shutdown
the computer and avoid data loss. Unnecessary peripherals
such as scanners and printers should not be connected to a
UPS as they can overload it.
