For most businesses, laptops and desktops should be replaced on a 3-year lifecycle. This is based on standard manufacturer support warranties.
Many organisations delayed device replacements during COVID. If that was you, there’s a good chance your fleet is now aging beyond its ideal lifespan.
In this article we are going to answer your FAQs about hardware lifecycles.
End of lifecycle can mean several things. It often refers to a device not being covered by manufacturer’s warranty if it breaks.
Another example of end of lifecycle is from last year when Microsoft Windows 10 went end of support. This means Microsoft no longer provide bug fixes or security updates for devices running on Windows 10. Older computers may not be able to run Windows 11 due to the hardware not meeting the necessary requirements, meaning that replacement is the only option.
It varies, but 3-5 years is a good ballpark for Computers, Servers, Firewalls and Network Hardware. By the time you get to 5 years, you will likely experience issues such as:

The short answer is risk and compliance. If you are running on hardware or software that is no longer supported, you put your business at risk. These risks include:
Now that the scary stuff is out of the way, let’s talk about the benefits of upgrading your hardware. These include:
We recommend conducting a simple fleet review:
For our FLEX Managed customers, we can provide an asset list with granular details and propose strategies for replacing devices (and budgeting for them!).
With the Australian Governments expected removal of the instant asset write-off provisions on 30 June 2026, planning your device upgrades has become even more timely. Waiting may not provide the same financial advantages it once did. That’s why we strongly recommend reviewing and planning your replacements now.
If upfront capital spend is a concern, there are options:
Spreading the cost across predictable monthly payments can make staying current far more manageable.
If you deferred device replacements during COVID, you’re not alone. But aging hardware can quietly impact productivity, security, and costs. A proactive review now can save you time, money, and headaches later.
We can identify what needs to be addressed and work with you to create a strategy based around urgency, your priorities, budget and unique compliance and risk standards.
