Laptops rarely fail without warning. Most give small signs weeks before a repair turns into a rescue. Spotting them early usually means a cheaper fix and far less risk to your files.
1. It takes ages to start or open apps
Some slowdown is normal as software grows, but a sudden change is worth a look. Common causes are a nearly full drive, too many programs starting with the computer, unwanted software, or a storage drive that is starting to fail.
2. The fan is loud and the base feels hot
Dust builds up inside vents and on the cooling fan over time. When air cannot flow, the laptop runs hot, slows itself down to cool off and may switch off suddenly. A professional clean is a quick job compared with replacing parts damaged by heat.
3. The battery drains fast or the case is lifting
Batteries wear out with use, so shorter battery life on an older laptop is expected. A battery that swells is different: if the keyboard or trackpad starts to bulge, or the case no longer closes flat, stop using and charging the laptop and have it checked as soon as possible.
4. Clicking noises, freezes or files that will not open
On laptops with a traditional hard drive, clicking or grinding sounds can mean the drive is failing. Random freezes, error messages and files that will not open can point the same way on any drive. Back up your important files straight away, then book a check.
5. Pop-ups, new toolbars or settings you did not change
Unexpected pop-ups, a browser homepage that keeps changing or security software that has been switched off can be signs of unwanted software. Avoid typing passwords or banking details on the device until it has been cleaned.
What to do next
- Back up your documents and photos to an external drive or a cloud service
- Write down when the problem started and anything that changed around that time
- Bring the charger with the laptop, as charging faults are common
- Ask for a diagnosis and a written quote before any repair starts
