How to Test Your Laptop’s Battery
A laptop battery provides power for a laptop when it is not plugged into a power source. The power cord that charges a laptop battery is called the AC Power Adapter.

Factors that affect battery life are battery age, size, type, and use. There are a few different tests to estimate of how long a battery lasts and to see if it is time to replace the battery.

The amount of time remaining on a laptop battery can be measured by the battery icon on the taskbar at the bottom right corner of the laptop screen. Most laptops only give the percentage of time remaining and not the specific amount of time left before the battery dies.

Laptop batteries can fail, or over time can lose their ability to hold a charge. If your laptop suddenly stops cooperating, you can usually determine if a bad battery is causing the problem by removing it from its bay (on the bottom or side of the laptop) and running the laptop from the AC adapter only. If the batteryless laptop runs properly when connected to the adapter, the battery has most likely kicked the bucket, shuffled off its mortal coil, and otherwise become defunct.

If, in the other hand, your batteryless laptop doesn’t run when connected to the AC adapter, either the adapter or the laptop’s internal electronics have failed. If you can borrow a known-good adapter, use it to see if the problem is caused by the cords or converter or if the issue lies deeper within the laptop itself.
