HP Notebook PCs - Battery not detected in Windows

Sometimes Windows does not detect the presence of a battery. This can occur even if your battery is working properly. To try to resolve this issue, try the following possible solutions.

Note:

If you notice your notebook battery is swollen or deformed, see HP Notebook PCs - Swelling or deformation of notebook battery for more information.

After each step, test the battery to see if the procedure worked. You can test the battery while the AC power is connected or when the notebook is running on battery-only power.

Perform a hard reset

Performing a hard reset erases all the information that is stored in your notebook's temporary memory. This forces Windows to do a complete scan of the system, including the battery.

Restore default BIOS settings (notebook PCs)

Restore the default BIOS settings to return the BIOS to the factory settings that your notebook was shipped with.

Note:

BIOS configurations vary, depending on computer model. For more information about accessing and navigating the BIOS menu, see the documentation for your computer model.

  1. Press the power button to turn on the notebook and repeatedly press f10 to enter the BIOS setup.

  2. Navigate through the BIOS and select the option to restore the BIOS defaults. The option is called Restore Defaults or Setup Defaults, or something similar.

  3. Confirm that you want to restore the BIOS defaults, and then select the option to save and exit the BIOS setup.

    The computer restarts using the default settings.

Update the BIOS

You can download and install the latest update for your BIOS to update it to the latest version.

For instructions on updating the BIOS, see HP Consumer Notebook PCs - Updating the BIOS (Basic Input Output System) (Windows) or HP Business Notebook PCs - Updating the BIOS (Basic Input Output System).

Determine if the notebook starts using battery only

To determine if the notebook can start using battery power only, disconnect the AC power from the notebook PC and then try to boot the notebook PC on battery-only power.

Test the battery

HP provides several different tools you can use to test the battery.
