Short answer: replace a business laptop when it no longer gets security updates, when its warranty and support have run out and repairs start adding up, or when it is slowing your team down enough to cost real time. Many businesses plan around a three to five year cycle, but the right timing depends on how the device is used and how well it has been looked after.
Below we’ll walk through the warning signs, how to plan replacements so they don’t all land in the same month, and how to retire old laptops without leaving your data behind.
Why laptop age matters more than you think
An old laptop that still turns on can feel like a bargain. The hidden costs tend to creep in quietly:
- Lost staff time waiting for slow start-ups, frozen apps and spinning wheels.
- Security risk once the operating system or hardware stops receiving updates.
- Repair costs after the warranty ends, plus the downtime while a device is out of action.
- Compatibility problems when newer software or Microsoft 365 features need more than the machine can give.
Seven signs a laptop is due for replacement
1. It can't run a supported operating system
This is the big one. Microsoft ended support for Windows 10 in October 2025, which means no more regular security fixes for most users. Laptops that can’t meet Windows 11’s hardware requirements are now running on borrowed time. The Australian Cyber Security Centre consistently recommends keeping operating systems patched and moving off unsupported versions, so an unsupported device is a genuine business risk, not just an inconvenience.
2. The warranty has expired and repairs are piling up
A single battery replacement can be worth it. A new battery, then a keyboard, then a hinge, then a screen is a sign the device is wearing out. As a rough rule, if a repair costs a sizeable chunk of what a replacement would, put that money toward a new machine instead.
3. The battery won't last a meeting
If a laptop has quietly become a desktop because it can’t survive unplugged, your team has lost the flexibility you paid for. Swelling batteries are also a safety issue and should be dealt with promptly.
4. Everyday tasks are painfully slow
Some slowness can be fixed with a clean-up, more memory or a solid-state drive. But if a well-maintained laptop still struggles with email, browser tabs and video calls, it has likely hit its limit.
5. It can't handle the tools your business now relies on
Video conferencing, cloud apps and modern security software all ask more of a device than they did a few years ago. If a laptop is holding back how your team works, it’s costing you.
6. Storage is constantly full
Moving files to the cloud helps, but tiny or ageing drives that are always full lead to failed updates and crashes.
7. It's the odd one out
A mix of ages, brands and models makes support harder and slower. Standardising on fewer models usually makes life easier for everyone, including your IT provider.
How to plan a laptop refresh cycle
The goal is to avoid the scramble of replacing everything at once, or worse, replacing laptops one emergency at a time.
- Build a simple register. List every laptop with its user, model, purchase date, warranty end date and operating system. A spreadsheet is fine to start.
- Set a target lifespan. Choose a cycle that suits your work. Staff doing heavy design or data work may need upgrades sooner than those mostly on email.
- Stagger replacements. Replacing a portion of your fleet each year spreads the cost and keeps budgets predictable.
- Buy business-grade devices. Business models typically offer longer warranty options, better build quality and management features that consumer models may lack.
- Match warranty to lifespan. If you plan to keep laptops for four years, consider warranty cover that runs that long.
- Review once a year. Check the register, flag devices nearing end of life and budget accordingly.
Don't forget device management
Lifecycle planning works best alongside good everyday management. That means making sure every laptop has:
- Automatic operating system and app updates turned on
- Disk encryption enabled, so a lost laptop doesn’t mean lost data
- Multi-factor authentication on business accounts
- Files saved to cloud storage or a backed-up server, not just the local drive
- The ability to be locked or wiped remotely if it goes missing
Retiring old laptops safely
An old laptop can hold years of client details, invoices and saved passwords. Under Australian privacy law, many businesses have obligations to protect personal information, and the OAIC provides general guidance on destroying or de-identifying data you no longer need. Before a laptop is sold, donated, recycled or handed to a staff member:
- Confirm the data is backed up or migrated to the new device.
- Sign the device out of Microsoft 365, cloud services and any management tools.
- Securely erase the drive using a proper wiping method, not just deleting files or emptying the recycle bin. If the drive is faulty, physical destruction may be the safer option.
- Record what happened to each device in your register.
- Recycle responsibly through an e-waste program rather than general rubbish.
Getting the timing right
There is no single magic age for replacing laptops, but there are clear signals: no more security updates, rising repair costs, and staff losing time to slow machines. A simple register, a staggered plan and secure disposal will save you from most hardware headaches. Think of it as feeding your office monster on a schedule, rather than waiting for it to get cranky.

Frequently asked questions
How long should a business laptop last?
Many businesses plan around three to five years, but it depends on the device quality, how heavily it’s used and how well it’s maintained. The key test is whether it still receives security updates and runs your software reliably.
Is it worth upgrading an old laptop instead of replacing it?
Sometimes. Adding memory or a solid-state drive can extend a laptop’s life if it’s otherwise healthy and can run a supported operating system. If it can’t get security updates or repairs keep stacking up, replacement is usually better value.
Can I keep using Windows 10 laptops in my business?
Microsoft ended mainstream support for Windows 10 in October 2025, so most devices no longer get regular security fixes. Running unsupported systems increases your cyber risk, so plan to upgrade compatible laptops to Windows 11 and replace those that can’t be upgraded.
Is deleting files enough before getting rid of an old laptop?
No. Deleted files can often be recovered. Use a proper secure wipe of the drive, or physically destroy a faulty drive, and make sure the device is signed out of all business accounts first.
