Hardware replacement is one of those things small businesses tend to get backwards. They'll replace a laptop the moment it slows down (probably just needs RAM and an SSD), and they'll keep a 9-year-old server running until the morning it doesn't boot and takes their files with it.
Here's a practical schedule, with the warning signs that mean "now," not "eventually."
The expected lifespan table
| Device | Typical lifespan | Replace earlier if |
|---|---|---|
| Business laptop | 4–5 years | Battery won't hold charge, OS no longer supported, employee productivity gated by speed |
| Workstation / desktop | 5–6 years | OS unsupported, can't run current required software |
| Server (on-premises) | 5 years | Past warranty, no spare parts, hosting business-critical services. Honestly, consider going cloud instead. |
| Network switch | 7–10 years | Out of vendor support, can't push current Wi-Fi standards |
| Wi-Fi access point | 5–7 years | Pre-Wi-Fi 6, performance issues, dropping clients |
| Firewall / router | 5 years | End-of-life software updates from vendor — this is non-negotiable |
| POS terminal (iPad) | 4–5 years | POS vendor drops iOS support for that model |
| Printer | 5–8 years | Driver no longer signed for current OS, parts unavailable |
| Phone (desk VoIP) | 6–8 years | Vendor end-of-life, codec compatibility issues |
| UPS battery backup | 3–5 years (battery) | Self-test fails, runtime under 50% of original |
The "replace it now" warning signs
Software/security warning signs
- The operating system or firmware is no longer receiving security updates from the vendor (Windows 10 EOL, old Mac models, EOL Cisco gear)
- You can't install required business software because the OS is too old
- Vendor has officially deprecated the model — you can usually find a public end-of-life statement
Performance warning signs
- Boot time over 3 minutes, daily
- Frequent crashes, freezes, or app force-quits
- Wi-Fi router dropping clients more than once a week
- Print queue stalls daily even after troubleshooting
Reliability warning signs
- Hard drive making clicking sounds, S.M.A.R.T. errors, or unexplained slowness
- Battery cycle count past 1000 on laptops, or won't hold a charge through a meeting
- UPS battery self-test fails or runtime is dropping
- Printer paper jams more often than once a week, or gear noise during operation
Rule of thumb: if a piece of hardware is no longer getting security updates, it's not "old," it's a liability. Replace it on a calendar, not when it breaks.
The "wait" cases
Don't replace just because it's old:
- A 4-year-old laptop with 8GB RAM that feels slow. Add RAM (often $50) and confirm it has an SSD. You'll get 2 more years of performance for less than 10% of replacement cost.
- A 5-year-old desktop running specialized software. If it works, the software vendor still supports it on that OS, and the security patches are current — no replacement needed.
- An older Wi-Fi router that's still rock-solid in a small space. If it's getting firmware updates and isn't dropping clients, leave it. Wait until it actually fails the user.
- A printer that's just dirty. Most "broken" printers in our experience need a deep clean of the rollers, not a replacement. Try that first.
The 3-year refresh cycle vs. 5-year
Big enterprises run 3-year laptop refresh cycles because they can deduct it on a schedule and they value the productivity uplift. Small businesses generally don't need that — a 4–5 year laptop cycle works fine if you spec the hardware well to start with.
What "spec well" means in 2026:
- 16GB RAM minimum, 32GB if the user runs design or video
- 512GB SSD minimum — never spec a 256GB drive in 2026
- For Windows: an Intel Core Ultra or AMD Ryzen 7000-series or newer
- For Mac: any M-series chip from M2 onward; M3+ preferred for new buys
- USB-C charging — eliminates the "we need three different chargers" nightmare
Spec it right and the laptop is still good after 5 years. Spec it cheap and you're back at the store in 2.
Why we hate "we'll replace it when it dies"
Reactive replacement always costs more — not in the hardware, in the downtime. The morning the server doesn't boot, you don't have hours to research options. You buy whatever the local shop has in stock, you pay for emergency labor, and you're down half a day at minimum.
Even an annual hardware-review meeting (an hour, in a calendar, with a list of every device's age and warranty status) prevents almost all of these surprises. We do this with our managed-IT clients quarterly. Take 10 minutes to do it yourself if you're not working with us yet.
