Looking after hardware.
WHY IT MATTERS
Heat and dust cause more failures than anything else.
WHAT DUST DOES
Blocks airflow, causing overheating, which causes shutdowns and shortens life.
WHAT TO DO
Keep vents clear Clean dust periodically Keep the machine off carpet and soft surfaces Ensure space around it
WHAT TO BE CAREFUL WITH
Liquids near the keyboard Screens cleaned with unsuitable products Cables pulled at an angle
WHAT TO USE ON SCREENS
A soft dry cloth, or a product intended for screens.
WHAT NOT TO USE
Household cleaning products, which damage coatings.
WHAT TO DO ABOUT A SPILL
Power off immediately, disconnect, and turn it upside down.
Do not switch it on to check.
WHAT ELSE MATTERS HERE
Power stability.
WHAT TO USE
Surge protection, at minimum A backup power supply, where interruptions are frequent
WHY
Sudden loss of power corrupts data and damages hardware over time.
WHAT TO CHECK
That fans still run, and that the machine is not unusually hot.
