Repair or replace? When it's worth fixing an old computer
By Bhavesh Narsai · Published 1 July 2026 · Updated 13 July 2026
When a laptop or PC starts playing up, the big question is whether to spend money fixing it or put that money towards a new one. There is no single right answer, but there is a simple way to think about it. Here is the honest version, including the times I would tell you not to bother repairing.
Quick answer
It is usually worth repairing if the fix is cheap relative to a new machine, an SSD or RAM upgrade, a clean-out, or a new battery. It is usually not worth it if an expensive part fails on an old laptop, or the repair costs more than about half the price of a suitable replacement. Either way, back up your files first.
Usually worth repairing
Some problems are cheap to fix and give an old machine years more life. If the computer is otherwise fine, these are almost always worth doing:
- It is just slow. An SSD upgrade and a bit more memory can make a five-year-old laptop feel new, for a fraction of the price of replacing it.
- A virus or a software mess. A clean-out costs far less than a new machine.
- A worn-out battery or a full drive. Cheap, quick fixes.
- One clear faulty part on an otherwise good computer. Often economical to replace.
Often not worth it
Other times, honestly, you are better off putting the money towards a replacement:
- An expensive part on an old machine. A new screen or motherboard for a laptop that is already 7 or 8 years old rarely makes sense.
- The repair costs a big chunk of a new one. A rough rule: if a fix costs more than about half the price of a suitable replacement, think hard.
- It is too old to do what you need. If it struggles even when healthy, fixing it just buys you a slow computer.
- Liquid damage or several faults at once. These add up quickly.
Whatever you decide, save your files first
Before repairing or replacing anything, make sure your photos and documents are safely backed up. If you are moving to a new machine, getting everything across cleanly is often the bit people dread, and it is exactly the sort of thing worth having a hand with.
Common questions
Is it worth repairing a 5-year-old laptop?
Often yes. A five-year-old laptop that is only slow can usually be transformed with an SSD upgrade and a little more memory for a fraction of the cost of replacing it. It is less worth it if an expensive part like the motherboard or screen has failed, or several things are going wrong at once.
Why is my laptop so slow, and is it worth fixing?
Nine times out of ten a slow laptop is an ageing hard drive rather than a machine that is past it. Swapping to an SSD is a cheap fix that makes an old laptop feel new, so it is almost always worth doing before you consider replacing it.
How do I know when a computer is not worth repairing?
As a rule of thumb, if the repair costs more than about half the price of a suitable replacement, or an expensive part has failed on a machine that is already seven or eight years old, replacing is usually the smarter move. The same is true if it struggles even when healthy.
