HP Notebook PCs - Battery does not power notebook or hold a charge

The removable battery of your HP notebook might not hold a charge due to a faulty power supply or AC adapter and might need to be replaced after testing all components.

If your notebook computer battery does not power the notebook or hold a charge, troubleshoot the battery to see if it needs to be replaced. If the battery indicator light, located near the power icon, does not glow or always blinks, there is a battery problem. Your computer might operate correctly when it is connected to the AC adapter, but not when using battery power.


To check if your battery is affected by the notebook computer battery recall and replacement program, go to HP Notebook Computer Battery Safety Recall and Replacement Program.


The maximum capacity of the battery decreases over time and with use. Loss of battery capacity varies depending on the product configuration and usage, including but not limited to: product model, applications running, power management settings, and product features. The battery warranty does not cover natural deterioration of battery capacity. Your battery is warranted from defects in materials or workmanship resulting in failure. When contacting HP Customer Support, you might be required to run an HP diagnostic test to determine if your battery is covered under the warranty.

Troubleshoot the notebook power supply

Verify that your notebook is connected to the AC adapter shipped with the product to prevent damage to your notebook battery.

Use the following steps to check the AC adapter and power source.

Before troubleshooting the notebook battery, make sure that the power supply is functioning properly.

  1. Verify that you are using the AC power adapter that came with the computer.

    The computer was shipped with the correct power adapter; however, if you have multiple adapters, make sure that you are using the correct one for your computer.

    Older adapters were rated at 60 watts, but newer notebooks require adapters with 90 or 130 watts.

    If you need to purchase a replacement AC power supply/adapter, make sure that you use the model number of the computer and check for the correct part number for the adapter at the HP Parts Store. You will also need the model number if you call HP Customer Support. See HP Notebook PCs - How Do I Find My Product Name or Number?.

  2. Plug the AC adapter into a functioning wall outlet, not a power strip, surge protector, or secondary power source, and then make sure that the notebook is receiving power from the power source by checking the following:

    • Unplug the AC power cable from the notebook, and then remove the notebook battery. Plug the AC power cable back into the notebook and turn it on. If the notebook turns on, the problem is with the battery. Go to Troubleshoot the notebook battery.

      If the notebook does not power on, continue reading this list of things to check.

    • Verify that the power cord is securely connected to the computer and to the AC adapter.

      If the AC adapter connection to the computer is loose, the connector might be damaged and require repair. Contact HP for further assistance.

    • Verify that the power button or power light is illuminated when the computer is on.

      Depending on the model, the battery indicator light (also called the power LED) might be white, green, or amber when the power adapter is connected and is providing power to the computer. If the power light is off, then continue reading this list of things to check.

    • If the AC adapter brick features an LED power indicator, check to see if the light is lit to verify that the computer is receiving power from the wall outlet. If the light does not turn on, try plugging the AC adapter into a different outlet to check the power source. If the light still is not lit, you might need to replace the AC power adapter.

    • Feel along the length of the AC power cable and check for any kinks or breaks. Check the ends for any broken connections. Inspect the AC adapter brick. If it is discolored or warped, or if there are any problems with the power cord or connections, replace the AC adapter.

Test the AC adapter using the UEFI Hardware Diagnostic tests

Run a UEFI Hardware Diagnostic test to identify any issues with the AC adapter.

If the computer starts and you would like to test the AC adapter, use the following steps:

  1. Make sure that the power cord and AC adapter are connected to the system and wall outlet.

  2. Press and hold the power button until the computer turns off completely.

  3. Turn on the computer.

  4. Immediately press the f2 key repeatedly, about once every second, until the UEFI Hardware Diagnostics screen is displayed.

  5. In the UEFI Main menu, select Component Tests.

    UEFI Main menu with Component Tests selected
  6. In the Component Tests menu, select Power.

    UEFI Component Tests menu with Power selected
  7. In the Power menu, select the AC Adapter test.

    Power Tests menu with AC Adapter selected
  8. Run the test and follow the onscreen instructions.

    Running the AC Adapter Test

When the test is finished, the results display.

Example of AC Adapter Test results

If the test PASSED, there is no issue with the AC adapter. Do not replace it.

If the AC adapter fails the test, write down the information so you have it available when you contact HP Customer Support.

Troubleshoot the notebook battery

Before beginning with this procedure, verify that the removable battery is undamaged, charges normally, and powers the notebook before considering battery replacement. Also, turn the computer over and look for a battery compartment door. If there is no battery compartment , you cannot perform these steps.

If you have verified that the AC power supply is functioning correctly, use the following steps to troubleshoot the battery:

  1. Remove the notebook battery and check the contact points to make sure that they are not damaged.

  2. Unplug all USB devices from the notebook.

    Many notebook models continue to provide power to USB devices through the USB ports, even when the computer is turned off or in a suspended state.

  3. Disconnect the AC power cable.

  4. Insert the battery into the battery compartment on the bottom of the notebook computer.

  5. Plug the AC adapter into the computer and into an AC wall outlet, and then allow the battery to charge for 15 to 30 minutes.


    The power light, located near the power icon, glows while the battery is charging.

  6. Unplug the power cord from the notebook.

  7. Press and release the Power button to start the computer using only the battery as the power source.

  8. If you have a second battery for your computer, replace the original battery with the second battery and perform the troubleshooting steps again.

    • If the computer turns on with the second battery and the battery charges correctly, contact HP Customer Support for battery replacement. See HP Notebook PCs - Purchasing a Replacement Battery.

    • If the problem remains with the new battery, you might need to replace the system board. Contact HP Customer Support for further assistance.
