Fix: Laptop overheated and won’t turn on
A laptop may refuse to turn on after overheating until it cools down. Blocked vents, dust, heavy apps, bad fans, or thermal problems can cause this.
Quick answer
Unplug the laptop, let it cool on a hard surface for 20–30 minutes, check that vents are clear, then try turning it on again.
Important warning
If the laptop smells burnt, has a swollen battery, or becomes extremely hot, stop using it and get professional help.
Try this
- 1 Unplug the charger.
- 2 Move the laptop to a hard, flat surface.
- 3 Let it cool for 20–30 minutes.
- 4 Make sure vents are not blocked by bedding, dust, or a case.
- 5 After it cools, plug the charger back in.
- 6 Try turning it on.
- 7 If it turns on, close heavy apps and check fan noise.
- 8 If it repeatedly overheats or shuts down, get the cooling system checked.
