Buying a computer
Define the workload, operating system, mobility needs and budget before comparing models. Then evaluate processor class, memory, storage, display, ports, warranty and upgradeability. Our computer buying guides cover each decision in more depth.
Maintaining a computer
Keep the operating system and applications updated, maintain backups, leave adequate free storage space and keep vents clear. Remove unused software and review startup applications when performance begins to decline.
Upgrades and repairs
SSD and memory upgrades can extend the useful life of compatible systems. Before repairing an old computer, compare the repair cost, remaining software support and likely working life against replacement.
Protecting your data
Use multi-factor authentication, unique passwords and a tested backup plan. If data is valuable, do not wait for a failing drive before creating a second copy.
