    Laptop Randomly Shutting Down

    Quick Answer

    Random shutdowns are often caused by overheating, power issues, or hardware failure. The laptop's thermal protection system will force a shutdown if the CPU gets too hot.

    Quick Checks

    Try these fast checks first — they solve most cases.

    1. 1

      Check for overheating

      Feel the bottom — if it's very hot, overheating is likely.

    2. 2

      Clean the vents

      Dust-clogged vents cause overheating shutdowns.

    3. 3

      Check the battery

      A failing battery can cause random power loss.

    4. 4

      Check power settings

      Ensure sleep/hibernate timers aren't set too aggressively.

    5. 5

      Run on AC power only

      Remove the battery (if possible) and run on charger only.
