Why does my laptop get hot and switch off?
Switching off from heat is a safety cut-out. The real cause is usually blocked vents, a dusty fan or dried-out thermal paste.
It usually needs a technician, but it's rarely an emergency. The checks below are safe to try first.
Does this sound like yours?
- It gets hot and switches itself off
- It's too hot to touch underneath
What usually causes it
- Vents or fan clogged with dust
- Thermal paste dried out and needs replacing
- Fan failing or stuck
Most likely first. A hands-on test confirms which one it is.
What you can safely check
- Use it only on a hard, flat surface, never on a bed or cushion
- Gently blow compressed air through the vents
Please don't
- Don't open it to clean the fan yourself unless you're experienced
- Running hot for long periods can permanently damage the processor and motherboard
