A laptop that shuts down without warning is trying to protect itself — most often from heat, but sometimes from a power or battery fault.
Most Common Causes- Overheating — the #1 cause. Dust-clogged fans and old thermal paste make the CPU hit its safety limit and cut power.
- Failing battery — a worn battery can cause sudden shutdowns when unplugged.
- Faulty charger / loose DC jack — power drops mid-use.
- RAM or storage errors — can trigger crashes and restarts.
Start with a cleaning and thermal repaste to rule out overheating (the most likely culprit). If it shuts down only on battery, the battery needs replacing. A diagnostic quickly identifies whether it is heat, power, or a component fault.
