One of the most common — and most worthwhile — services we do in our workshop: cleaning the inside of a laptop. It's cheap, quick, and can add years to your machine's life.
Why do laptops fill up with dust?
Laptops have fans that pull in air from the room to cool the components. That air also carries in dust, hair and fibres, which build up on the heatsink and fan into a layer that blocks airflow.
What happens if it's never cleaned?
Overheating
The processor and graphics chip generate a lot of heat. If that heat can't escape properly, components reach dangerous temperatures (90-100°C or more). At that point the operating system automatically throttles the processor to prevent damage — the laptop slows down.
Sudden shutdowns
If the temperature crosses a safety threshold, the computer switches itself off without warning. If your laptop shuts down mid-task, overheating is the first thing to rule out.
Permanent component damage
Excessive heat sustained over years can permanently damage the processor or motherboard. A €30-40 clean can prevent a €200-400 repair.
How often should a laptop be cleaned?
In a clean environment, every 2-3 years. If you have pets, smoke indoors, or use the laptop on the floor, every year to eighteen months. If the fan is noisier than usual or the laptop runs hotter, it's time.
What is thermal paste, and why does it need renewing?
Thermal paste is a compound that improves heat transfer between the processor and the heatsink. It dries out and loses effectiveness over the years. Renewing it during a clean can reduce processor temperature by 15-25°C — a very noticeable performance difference.
Can I clean it myself at home?
Compressed air through the vents can reduce surface dust somewhat, but a proper clean means opening the laptop and removing the heatsink. We recommend leaving that to a technician to avoid damaging any components.
