When to Replace Ageing Business Hardware

Ageing hardware almost never announces itself. There is no dramatic failure, no smoke. There is just a laptop that takes four minutes to be usable in the morning, a spreadsheet that hesitates when you scroll, and a staff member who has learned to go and make coffee while a file opens.

That is why old equipment survives budget conversations. Nothing is broken. It is simply costing you money in units too small to notice.

Do the arithmetic before the argument

The case for replacement is not "these are old." It is a number, and the number is usually larger than the hardware.

Suppose a machine wastes fifteen minutes of a staff member day — boot time, application launches, the general treacle of an overloaded disk. That is 1.25 hours a week. Across 46 working weeks, about 57 hours a year.

At a fully loaded cost of $55 an hour, that is roughly $3,150 a year, per person. A decent business laptop costs $1,600 and lasts four years. The maths is not close, and fifteen minutes a day is a conservative estimate for a machine people complain about.

Run this calculation for your own numbers before you ask for budget. It converts "the computers are slow" — an opinion — into a figure a director can act on.

The two dates that are not negotiable

Separate from performance, there are hard deadlines where the decision is made for you.

Operating system end of support. When Microsoft stops issuing security updates for a version of Windows, every machine still running it becomes permanently vulnerable to anything discovered afterwards. Not "less secure" — permanently exposed, with the gap widening every patch Tuesday.

This matters commercially as well as technically. Cyber insurance applications increasingly ask whether you run supported operating systems, and unsupported systems can affect a claim. Client security questionnaires ask the same question, and for anyone tendering into government or enterprise work, the honest answer can lose you the contract.

Hardware end of warranty. Out-of-warranty equipment means the replacement part is whatever you can source, on whatever timeline, at whatever price, in the middle of an outage.

Replace on a rhythm, not in a panic

The worst way to buy IT equipment is all at once, under pressure, because something died. You pay retail, you take what is in stock, and three years later you get to do it all again simultaneously.

A rolling refresh fixes the cash-flow problem and the risk problem together. Replace roughly a quarter to a third of your fleet each year on a four-year cycle. The spend becomes a predictable annual line rather than an occasional crisis, the fleet never gets uniformly old, and a failure affects a few machines rather than the entire office.

It also makes standardisation possible. One or two approved models, same image, same dock, same peripherals. Support gets dramatically simpler when every machine is one of two known quantities.

What to actually buy

For most office work in 2026, the specification that matters is unglamorous:

• 16GB of RAM minimum. This is the single biggest driver of day-to-day responsiveness. A browser with thirty tabs, Teams, Outlook and a line-of-business app will exhaust 8GB before morning tea.
• An SSD, always. If any machine in your business still has a spinning hard disk, that machine is the reason its user thinks computers are slow.
• A current-generation processor with the security features modern Windows expects, so the machine is not obsolete for compliance reasons halfway through its life.
• A business-grade warranty, ideally next-business-day onsite. Consumer laptops are cheaper for a reason, and the reason is what happens when one breaks.

Resist buying the cheapest machine that technically runs the software. The gap between a $900 laptop and a $1,600 one is about two years of useful life and a great deal of daily friction.

Servers: a different question

When a physical server approaches end of life, the real decision is not which server to buy. It is whether to buy one at all.

Some workloads genuinely belong on-premises — large media files, latency-sensitive applications, sites with unreliable internet. Plenty of others are simply running on a box because that is where they have always run. A server refresh is the natural moment to ask whether that workload should move to Azure or Microsoft 365 instead, and to answer honestly rather than by habit.

If the answer is that you still need hardware, our server infrastructure team can size it for the next five years rather than the last five.

Disposing of the old gear properly

Retired equipment is a data-breach risk sitting in a storeroom. A deleted file is not a gone file, and "we formatted it" is not sufficient for a drive that held client records.

Every retired device needs certified data destruction — cryptographic erasure or physical destruction — with a certificate recording what was destroyed and when. Under the Australian Privacy Principles you are obliged to take reasonable steps to destroy or de-identify personal information you no longer need, and a laptop on a shelf is neither destroyed nor de-identified.

Turning it into a plan

A refresh plan is four columns: every device, its age, its support status, and its replacement year. Once that exists, the annual conversation stops being an argument about whether things are slow and becomes a budget line everyone can see coming.

A short IT audit produces the first version of that table, and our virtual CIO service keeps it current so the plan survives past its first year.
