Here’s a checklist of items to troubleshoot your laptop’s battery draining quickly:

1. If your laptop battery life has decreased considerably, check to see if the computer is running too many applications at once.
2. Check to see if all of your laptop’s settings are set to optimize battery life.
3. Confirm that your computer is running the latest system updates.
4. Make sure your laptop isn’t plugged into an outlet for an extended period of time.
5. Check to see if your laptop is overheating, which can lead to shorter battery life.
6. Shut down or put your laptop into hibernate mode when you’re finished using it and before putting it away in a case.
