Your laptop shuts down suddenly without warning
Sudden shutdowns are the laptop protecting itself from overheating or from a battery that can't supply enough power. Feel the bottom of the laptop right before it shuts down. If it's too hot to hold, overheating is the problem. If it's cool, the battery is failing.
When a laptop gets too hot or when the battery can't supply enough power under load, Windows cuts power instantly to prevent hardware damage. This feels like a crash but it's actually protection kicking in. The fix depends on whether the laptop is hot or cool right before shutdown.
- ✓Feel the bottom of your laptop right before or after it shuts down to check if it's too hot to touch
- ✓Note whether shutdowns happen only on battery power or also when plugged in
- ✓Keep the laptop in a safe place after a shutdown in case the battery is damaged

Skip, I just want a technicianCommon mistakes to avoid
- Continuing to use the laptop on soft surfaces like beds and couches — this blocks airflow and causes overheating
- Ignoring a laptop that feels very hot — that's a warning sign that a shutdown is coming soon
- Using a laptop with a visibly swollen or bulging battery — this is a fire hazard and needs immediate replacement
Signs you need professional help
- If the battery report shows capacity below 60% of design capacity, or if vents are clear but shutdowns continue after switching to a hard surface, give us a call and we'll replace the battery or thermal paste for you.
