How to Troubleshoot a Laptop That Turns Off When Battery is On


Your laptop has a built-in battery that typically lasts several hours once completely charged (although the duration becomes less as the laptop ages). However, you may find your laptop turns off without you telling it to. There are a few different reasons this might occur, and usually you can troubleshoot the issue yourself without taking it to an expensive repair shop.

Things You'll Need

  • Power cable
  • Compressed air
  • Connect the laptop to a power source and turn it back on. The laptop's battery may be almost dead, and often a computer shuts down when there is little to no energy left in the battery.

  • Flip the laptop over and make sure the laptop battery is connected properly. The battery compartment needs to be flush with the rest of the laptop casing. If it is protruding, the battery isn't inserted properly. Open the battery compartment, pull out the battery, then slide it back in. Close the battery compartment and power the laptop back on.

  • Spray some compressed air into the vent on the bottom of the laptop. Dust building up on the vent causes the laptop to overheat. When a laptop overheats, the computer automatically shuts it down.

  • Set the laptop on a cooling tray. You can purchase a cooling tray from any store that sells computer products (including Target and Walmart). The cooling tray has fans that keep the laptop from overheating. This is a good product to use if you enjoy watching movies or playing video games on the laptop.
