Desktop computers in normal use areas are kept for 4 years.
Desktop computers in heavy use areas like computer labs are kept for 3 years.
Laptop computers are kept for an average of 3.5 years; some models last longer than others. Some people take better care of their laptops than others.
Servers are replaced at either 3 or 4 years depending on usage and performance variables.
The Manager of Information Systems decides whether to repair or replace damaged computers.
Peripheral devices include printers, cameras, scanners, iPods, external hard drives, LCD projectors, UPS battery backup units, and other devices connected either to computers or the network.
In general, networked printers are replaced after six years of service, earlier if cost of needed repairs exceeds 50% of replacement cost.
Precise replacement schedules for other peripheral devices are hard to predict since durability varies with use, make, and model. They are generally replaced when they fail or if repair costs are excessive.
Replacement cycle data is stored in the IS inventory database managed by Michele Wheeler. Call 4-1870 for that information.
