Attach the cable to your laptop computer (if it is not already.) If you are unsure where on your laptop to plug it in, examine the design of the connector and match it up with the input on the back of your laptop computer.

Press your laptop’s power button. If your laptop turns on and starts loading, then your battery is functional. If not, then your battery is not operating, and you should troubleshoot further from there.

Check the battery’s power percentage when your laptop is turned on and loaded. You can find this in the system tray in the lower right-hand corner of the screen.

If the battery charger is connected in, it will show how much from 100% you still have in the battery and it should say that it’s charging. When you unplug the charger, it will only tell you how much battery energy is staying.
