How to test your HP laptop battery









Laptop batteries fail after a couple of years. They can fail sooner than that or last longer, depending on the quality of the battery and your computing behavior. HP laptop batteries are no different. So how can you tell if your notebook battery is dying? This is something you need to know in advance so you can order a replacement. Fortunately, there are a few quick ways to test your HP laptop battery and arrange for a replacement, if necessary.



Use HP Battery Check To Test Your Laptop Battery



If you have a Windows 7 computer, it shipped with a utility to help you test your HP laptop. HP has a built-in utility called Battery Check, which runs a diagnostic on your battery to determine if it’s still capable of holding a charge and able to perform well. To run this, plug in your laptop ac adapter and make sure the computer is charged as much as possible. If the netbook battery is too weak, the test will not run properly. Once charged, proceed with the steps below:

  • Go to Start>HP Support Assistant.


  • Select Troubleshoot, then Power, Thermal and Mechanical.


  • Click Battery Check


  • You will then see either a diagram of a healthy battery or a warning stating the battery needs to be replaced.

    If the battery is bad, you will receive a warranty ID number. Use this number to see if your laptop battery is still under factory warranty. If it is, submit the request for a replacement immediately.



    If the battery is out of warranty, the screen will display that it is no longer covered.



    Symptom Of A Dying Laptop Battery



    One of the primary symptoms of a dying laptop battery is a battery that loses its charge quickly. Under normal circumstances, your laptop battery charge should last several hours. If it dies within less than an hour after unplugging it with a full charge, then the battery’s cells are getting weak and the battery should be replaced.



    Tips To Extend The Life Of Your Laptop Battery



    You can extend the natural life of your laptop battery by doing the following:

  • Remove the battery if the laptop will be plugged in for long periods of time.


  • Occasionally calibrate the laptop battery.


  • Routinely fully charge and discharge the battery.


  • Do not expose the battery to extreme heat.


  • Recycle Your HP Replacement Laptop Battery



    When your laptop battery does die, make sure you dispose of the old battery in a responsible manner. Laptop batteries are very toxic and should not be thrown away in the trash. Please refer to the HP Recycling Center for instructions on how to send you battery in for proper disposal.
