Notebook has battery warning on startup, but plugged into AC. Still shuts down after a few minuets. Even if battery is dead, does it matter if using with AC adapter plugged in?

Hi @mike791

Welcome to the HP Support Community. 

Troubleshoot the notebook power supply

Before troubleshooting the notebook battery, make sure the power supply is functioning properly. Use the following steps to check the AC adapter and power source.

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.

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

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

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

   • Verify that all power cord connections are secure. Check the AC adapter brick and make sure that any removable cords are secure.

     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 LED is illuminated when the computer is on.

     Depending on the model, the battery indicator LED (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 LED 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 LED is lit to verify that the computer is receiving power from the wall outlet. If the LED does not turn on, try plugging the AC adapter into a different outlet to check the power source. If the LED 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

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

1. Make sure the power cord and adapter is 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

Troubleshooting the notebook battery

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

NOTE: 

Before beginning with this step, turn the computer over and look for a battery compartment door. If there is no battery compartment , you will be unable to perform these steps

1. Remove the notebook battery and check the contact points to make sure 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 powered off or in a suspended state.

3. Unplug the AC power cable.

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

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

   NOTE: 

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

6. Unplug the power adapter 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 powers on, the battery is functioning. Run the HP Battery Check utility to evaluate the battery at Testing and Calibrating the Battery (Windows).
