Next, we’ll discuss common computer maintenance mistakes that contribute to the reduction in your computer’s lifespan. • Poor ventilation. Any obstruction to your computer’s vents will prevent necessary airflow to keep the hardware cool. This causes the fan to work harder, and the hardware will become hot when air has nowhere to escape. Heat is a big factor in damaging components. To prevent this, avoid using your computer near a heater or where it’s exposed to the sun. Also, if using it in bed, try to stop your blanket from blocking the air vents. • Power surges. A power surge could be caused by your refrigerator or washing machine for example. In a worst-case scenario, it can cause damage to your motherboard. Getting it repaired can be expensive. Consider using an outlet surge protector to protect your computer against a voltage surge. • Battery care. Help preserve the life of your laptop battery by unplugging it once it’s fully charged. Also, as much as possible, let it charge completely as opposed to unplugging it halfway through. If you leave your battery plugged in after it's 100% charged, overcharging will cause it to hold its charge less and less over time. • Prevent physical damage. Be as careful as possible when handling your computer. Take extra care when drinking and eating, as moisture caused by spills can cause rust.
