Look after your computer physically
Choose safe cleaning and ventilation decisions for everyday equipment.
Keep equipment clean and ventilated without unsafe dismantling.
A computer needs a stable surface, clear airflow and appropriate cleaning. Dust, blocked vents and spills can cause problems that software cannot fix. You do not need to open the case to carry out ordinary care, and different screen coatings and devices may need different cleaning methods.
Make the choice that fits your task
How this works
Find the care instructions for your exact model on its manufacturer’s site. Before cleaning, save work and shut down using Start, the power symbol and Shut down. Unplug power and accessories as the guide directs.
Use a soft, clean microfibre cloth for routine exterior cleaning. Apply only cleaning products and amounts permitted by the manufacturer. Never spray liquid directly at the computer or screen, and do not allow moisture into openings.
Keep ventilation openings clear. Use a laptop on a firm surface rather than bedding that can obstruct vents. Route cables so they are not strained or likely to pull the device off the table.
Do not open a power supply or force tools into ports. Internal dust removal and battery replacement require model-specific instructions and suitable skills. If the battery looks swollen, stop using and charging the device and seek qualified help.
Allow any permitted damp cleaning to dry fully before reconnecting. If liquid has entered the computer, do not switch it on just to see whether it still works; get advice about that model.
A laptop’s vents press into a soft duvet during use. What is the better arrangement?
