Summary: Three to five years is a practical replacement range for many business computers. The right time depends on security support, reliability, performance, warranty coverage, repair costs, and the employee’s work. Replace any computer that cannot run a supported operating system or the software your business requires.Most business computers do not fail all at once. A laptop may still handle email and documents but take longer to start, struggle during video calls, or run out of battery halfway through the day.For many office computers, three to five years is a sensible replacement range. Start reviewing each device when it reaches three years old, then decide whether it should be replaced soon or kept for another year or two.Some computers will need to be replaced sooner because they cannot install a supported operating system, no longer run important software properly, or require frequent repairs. Others may remain useful beyond five years,
