The single most important maintenance item that should be done on a regular basis is BACKUP YOUR DATA. What the
schedule is depends on much data you can afford to lose. Try daily/weekly to an external hard drive and monthly to a
CD/DVD, or use a backup application. Make sure that your software is updated; primarily the operating system and your
primary browser.
Use utility software: get a sense of how your computer operates when it’s operating correctly. For the Mac use ‘Activity
Monitor’ or ‘Tech Tools’. On the PC (in the control panel) administrative tools/performance. You can also check your internet
For the PC users--do regular spyware/virus scans.
Make sure the definitions are up to date. Primarily for PC
users--Defragment your hard drive (this may
take a while). Mac users do not really need to do this
since OS X (10.3 +) does it automatically.
Free up some space on your hard
drive (PC users can use disk cleanup; Mac
users can use CacheOutX). Clean
out old files that you don’t use, after you’ve
backed them up. Uninstall those
programs that you don’t use. Apple
recommends that you have at least
10% free, a bit more for PCs, this will improve
virtual memory and may improve disk
performance.
Clean the Hardware -- to clean the
monitor and keyboard use a dry microfiber cloth
(be sure the computer is turned off) and
gently (don’t press hard) wipe the monitor, unplug the
keyboard and wipe. If there are hard to clean areas,
spray the cloth lightly with a vinegar/water solution and then
wipe. For an optical mouse wipe the bulb gently. You’ll need to open a mechinal mouse to clean the rollers. Use a cotton
swab with isopropyl alcohol.
If your computer case is easy to open (i.e. not an iMac or Mac Mini), then open it up (after shutting down and unplugging it)
and use compressed air to blow out the dust. Do not use a vacuum since it may create a static charge that could damage
the electronics. After closing the case you can clean out the fan in the back.
You’ll also probably want to have the following tools:
• Screwdrivers--standard, phillips, and torx in different sizes (especially the small ones)
• Nutdrivers--1/4” and 3/16”
• Pliers, part grabbers, and tweezers
• Microfiber cleaning cloths
• Antistatic strap--especially if you want to put your hands inside the computer
