How long should a business computer last? It’s a question that sounds simple but has real implications for security, productivity, and total cost of ownership. The answer most business owners give — “until it stops working” — is one of the most expensive IT decisions they’re making without realizing it. Let us offer a more useful framework.
Standard Replacement Cycles by Device Type
- Desktop workstations: 4–5 years. Desktops are more durable than laptops and easier to service. A well-maintained desktop can perform adequately through year five, though security support considerations often define the practical ceiling.
- Business laptops: 3–4 years. Laptops experience more physical wear, battery degradation, and component stress from portability. The 3-year mark is where performance and reliability issues typically begin surfacing in earnest.
- Servers: 5–7 years, depending on workload and vendor support. Microsoft’s support timelines for server operating systems are often the binding constraint — once an OS reaches end-of-life, the security calculus changes regardless of hardware condition.
- Network equipment (switches, access points): 5–7 years, reviewed against current security standards. Equipment that was current in 2018 may have unpatched vulnerabilities today.
- Firewalls: Follow the vendor’s support lifecycle closely. A firewall running end-of-life firmware is a security liability regardless of its physical age.
The Security Case for Timely Replacement
The performance argument for replacing aging hardware is intuitive — nobody needs to be told that an 8-year-old machine with a spinning hard drive is slow. The security argument is less obvious but more urgent. Older hardware often cannot run current operating system versions. A machine that can’t run Windows 11 is a machine running Windows 10, which Microsoft no longer supports. End of support means no more security patches — and no more security patches means known vulnerabilities remain permanently open.
In a managed environment, we can extend useful life somewhat through careful configuration and security hardening. But there is a floor below which software cannot compensate for hardware limitations, and operating near that floor exposes the business to risks that competent management cannot fully mitigate.
The Hidden Cost of Keeping Aging Machines
The cost of a slow machine doesn’t appear on any invoice — but it accumulates. An employee who loses 20 minutes per day to a machine that’s slow to start, slow to open applications, and slow to process routine tasks loses more than 80 hours per year. At any meaningful wage, the productivity cost of that machine exceeds its replacement cost before the year is over.
Older machines also generate more helpdesk tickets and require more engineer time to support. That time has a cost that affects managed IT pricing at renewal. The true total cost of running hardware past its productive life consistently exceeds the cost of planned, timely replacement.
How We Handle Hardware Provisioning
We spec Lenovo ThinkStation/ThinkPad and HP EliteBook/ProDesk lines for the majority of our clients. These business-class lines are built to different standards than consumer hardware — more durable, longer warranty options, better driver support for enterprise management tools, and consistent specifications that simplify standardized deployment.
We provision new machines using standardized deployment tools that configure every workstation identically before it reaches the user’s desk: security settings, software stack, endpoint protection, encryption, all applied consistently. A new employee can be productive from day one. A replacement machine is ready the same afternoon.
Planning a Hardware Refresh
The right approach is proactive lifecycle planning, not crisis response. Every managed client at Acme has a device inventory with purchase dates, warranty status, and projected replacement years. That inventory feeds a multi-year hardware budget that eliminates the year where multiple major replacements cluster unexpectedly. If your organization doesn’t have a current hardware inventory, that’s a straightforward starting point. Reach out at Contact Us, to learn more!
