Hardware Refresh Checklist: When to Replace Your Business Computers and Equipment

Why Hardware Refresh Planning Matters

Most small businesses replace computers reactively — when one fails or becomes too slow to use. This approach is more expensive and disruptive than it needs to be. A computer that fails during a busy period costs downtime, emergency replacement costs, and data recovery fees if backup was not in place.

Planned hardware refresh is predictable: you know when replacements are coming, you can budget for them, and you can schedule them at a convenient time rather than an urgent one.

Lifespan Guidelines by Device Type

Signs a Device Needs Replacing Now

• Runs for more than two minutes to boot
• Consistently at 80%+ CPU or RAM usage during normal tasks
• Running an operating system past its end-of-support date (Windows 10 reached end of support in October 2025)
• Hard drive showing SMART errors (imminent failure warning)
• Battery holds less than 20% of original capacity (laptops)
• No longer receiving manufacturer security updates

What to Do Before Decommissioning Old Hardware

• Wipe all data securely — do not donate or dispose of computers without running a certified data erasure process
• Remove the device from your Microsoft 365 or MDM environment
• Retrieve and deactivate any software licences installed on the device
• Document the disposal for audit purposes if you handle regulated data (healthcare, financial services)

Building a Refresh Plan

A simple hardware register — a spreadsheet listing every device, its purchase date, and its expected replacement year — lets you plan and budget refreshes 12–18 months in advance. Most businesses refresh 20–30% of their device fleet each year on a rolling basis rather than a large-scale replacement every five years.

The Windows 10 End-of-Support Problem in SE Queensland

Windows 10 reached its end of support on 14 October 2025. From that date, Microsoft stopped issuing security patches for Windows 10. This means that every new vulnerability discovered in Windows 10 — and they are discovered regularly — is permanently unaddressed. These computers are progressively more dangerous to operate as targets for attack.

In SE Queensland, a significant proportion of small business computers are still running Windows 10. The reasons are understandable: replacement costs, disruption to workflows, and a "if it's not broken" mindset. But the security risk is not theoretical — attackers actively target known vulnerabilities in end-of-life operating systems.

The options for Windows 10 devices:

Upgrade to Windows 11. Windows 11 requires hardware that meets specific minimum specifications — primarily a processor from 2017 or later and TPM 2.0. Many computers that ran Windows 10 well do not meet these requirements and cannot be upgraded. Run the PC Health Check tool (available from Microsoft) on any Windows 10 computer to determine if it is eligible for Windows 11 upgrade.

Replace the device. For computers that cannot run Windows 11, replacement is the only path to a supported operating system. This is also an opportunity to upgrade performance: a new business laptop or desktop running Windows 11 will be meaningfully faster than a five-year-old machine that has accumulated software bloat.

Extended Security Updates (ESU) as a short-term measure. Microsoft offers paid ESU subscriptions that extend security updates for Windows 10 beyond the end-of-support date — at a cost of $30 USD per device per year, doubling each year. This is a short-term bridge, not a long-term strategy. Replacement is still necessary.

Network Equipment: The Often-Overlooked Refresh

Business computer refreshes get attention; network equipment often does not. But end-of-life network gear carries its own risks and performance implications.

Routers and firewalls. Ubiquiti UniFi and Meraki devices are popular in SE Queensland business environments. Firmware updates — which address security vulnerabilities — stop when a device reaches end-of-support. An unsupported firewall is particularly dangerous: it is the boundary between your network and the internet. Check the support status of your current firewall model against the vendor's end-of-life schedule.

Network switches. Unmanaged switches have no configuration, no firmware to update, and are generally safe to run until they fail physically. Managed switches have firmware that should be current. Review managed switch firmware currency annually.

Wi-Fi access points. Wi-Fi standards evolve, and older access points may not support current security protocols (WPA3) or provide adequate coverage for the number of concurrent devices in the business. Physical coverage issues — dead spots, dropped connections — are often symptoms of ageing access points rather than internet problems.

UPS batteries. Uninterruptible Power Supply units protect servers and networking equipment from power surges and brief outages. The lead-acid batteries in standard UPS units degrade over time — typically 3–4 years — and lose their capacity to hold a charge. A UPS with a failed battery provides surge protection but no runtime during an outage. Test UPS battery status annually and replace batteries proactively.

Buying Business Hardware in SE Queensland: Practical Considerations

Business vs consumer grades. Business-grade computers (Lenovo ThinkPad, HP EliteBook, Dell Latitude, Apple MacBook Pro) are built to more demanding specifications than consumer equivalents at a similar price point: more durable chassis, better thermal management, longer warranty periods, and better driver support. For daily business use, the premium over consumer-grade is justified.

Warranty. Business computers typically offer three-year on-site warranty options. For hardware that is critical to operations, next-business-day on-site warranty means a failed device is replaced within 24 hours rather than being sent away for depot repair.

Procurement lead times. Supply chain conditions affect lead times for business hardware. In SE Queensland, ordering specific configurations can take 2–4 weeks. Plan hardware refresh purchases well in advance of when they are needed — do not wait until the old device fails.
