Preventive Maintenance Flashcards
What are the benefits of preventative maintenance?
Reduces potential hardware and software problems, computer downtime, repair costs, and the number of equipment failures.
Improves data protection, equipment life and stability, and saves money.
What two factors are preventative maintenance plans developed off of?
Computer location or environment.
Computer Use.
Why is computer location/environment important?
Because dusty environments can cause dust build up, and in turn damage.
Why is computer use an important factor?
High traffic networks, such as school ones, may require more scanning and removing of malicious malware or unwanted files.
What should you dust with?
Cloth or duster for the outside of a computer case. if using a cleaning product, use a small amount for the outside only.
Compressed air, a vacuum cleaner or small lint free cloth works best for the inside of a computer.
Where should you dust?
Clean air filters regularly.
Outside and inside case.
Clean the cooling fans.
What should you be careful of when using compressed air?
That you hold it upright, so that dust does not leak into components.
That it is kept a good distance from sensitive components.
That you do not use it for everything. Use a small lint free cloth to tidy up.
Hold the fan blades in place, lest you cause damage to it.
What components should be checked for dust and damage?
CPU heatsink and fan. RAM modules. Storage Modules. Screws. Adapter cards. Cables. Power devices. Keyboard and Mouse.
Why is checking screws important?
Loose screws could cause a short circuit, damaging the system.
What should you do with cables?
Ensure that pins are not bent or broken, ensure that cables are not severely cramped or twisted.
Retaining screws should be finger-tight.
What is the aim with most component checks?
That everything is secure, working and dust free.
What are the general optimal operating conditions?
10% to 80% humidity.
45 to 90 degrees F. 7.2 to 32.2 degrees C.
Do optimal temperature and humidity factors vary by computer?
Yes, they vary by manufacturer. They should be checked for each device.
What aids the optimal operating environment?
Unrestricted airflow or air vents.
What should you do with software maintenance?
Verify that software installed is current.
Create/Follow a software maintenance schedule.
