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

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

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.

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

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.

   

6. In the Component Tests menu, select Power.

   

7. In the Power menu, select the AC Adapter test.

   

8. Run the test and follow the onscreen instructions.

   

When the test is finished, the results display.

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.

• If the AC adapter is defective and the computer is under warranty, contact HP with the failure ID code ready.

• If the computer is no longer under warranty, see HP Notebook PCs - Ordering HP Certified Replacement Parts.

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.

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.

   Note:

   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.

   • If the computer turns on, the battery is functioning. Run the HP Battery Check utility to evaluate the battery. See HP Notebook PCs - Testing and Calibrating the Battery (Windows).

   • If the computer does not turn on, continue to the next step.

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.
