Maintaining and Troubleshooting Computer Systems Computer Technology (S1 Obj 1-3)
Computer Protection • As the use of computers has grown in volume and importance, protecting computer systems and the information they hold has become increasingly important. • There are 3 ways to protect your computer • Against theft • Against physical damage • Data Security
Protecting Against Theft • Safeguards include: • Choose a secure location • Don’t leave it in the front seat of your car • Don’t leave unattended • Lock room or building (Motion detection alarms) • Use security locks • Used to anchor laptop to a fixed structure • Security lock slot can be found in 99% of computers • Mark equipment with identification marks • Ultra-V Pens • Computer security or asset labels • Record serial numbers at a separate location Theft of and damage to computers (desktop, laptop, mobile device) is a serious problem.
Protect Computer AgainstPhysical Damage • Improper Handling • Dropping: Use a padded case • Spilling: Use spill proof container or avoid food and drinks near computers • Overheating • Ensure proper cooling and ventilation • Accumulation of dust and debris could damage motherboard components • Humidity • Operate safely between 50-90 degrees • Too much moisture can short circuit wiring and cause corrosion
Protect Computer AgainstPhysical Damage • Electrical Damage • Caused by power surges, Power fluctuations, Static electricity • Use a Surge Protector (An electrical device inserted in a power line to protect computer hardware from sudden fluctuations in power) • Do not run motors or other heavy duty equipment (copiers, air conditioners, etc.) on the same circuit as your computer!
Data Security Computer failure is the #1 reason for data loss
Protect against Data Loss • Protect your data! • Backup data • Flash Drive • CD’s or DVD’s • External hard drive • Cloud • Password Protect • Should not be easy to guess • Keep private • Prevent remote access • Firewalls • Secure wireless access • Consult a professional if necessary!
Troubleshooting CommonHardware Related PC Problems • Troubleshooting means to find the source of a computer problem and fix it, usually through the process of elimination • Check electrical power source first • Plugged in securely? • Power to the surge protector? • Second, check the connections of peripheral devices • Make sure cables are secure • Unplug and reconnect the peripherals • Finally, if all lese fails, restart the computer
Preventative Maintenanceby User • Clean the PC and peripherals • Monitor, keyboard, mouse, vents • Avoid excess liquid to ensure electronics don’t get wet • Small bits of paper, dust or other debris could cause jams or ink/toner smears on printed papers • Replace or upgrade broken components • Replace ink/toner cartridges when empty • Replace peripherals • Virus Scan: configure your computer to update and run a virus scan daily or at least weekly
Specialized Maintenance • Some maintenance or repair should be performed by a computer professional • Replacing the power supply or opening the power supply case • Replacing other electrical components • Replacing or upgrading the processor • Replacing or upgrading the hard drive • Replacing or adding RAM (the best value for increasing processor speed) • If you are uncertain how to upgrade or repair your computer, consult a professional!
