Hi @myarborough,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

The "No battery installed" error on your HP laptop can be caused by various issues, such as a loose battery connection, a faulty battery, or a software glitch. Here are some steps you can try to resolve this problem.

Check the Battery Connection

• Power off the laptop and unplug it from the charger.
• Remove the battery if it's a removable type. If not, skip this step.
• Inspect the battery and the battery bay for any debris or dust. Clean if necessary.
• Reinsert the battery securely, making sure it's properly seated.
• Power on the laptop and check if the issue persists.

Update the Battery Drivers

• Open Device Manager: Press Windows + X and select "Device Manager."
• Expand the "Batteries" section.
• Right-click on Microsoft ACPI-Compliant Control Method Battery and select "Uninstall device."
• After uninstalling, click on "Action" at the top of the Device Manager and select "Scan for hardware changes." This will reinstall the driver.
• Restart your laptop.

Perform a Power Reset

• Shut down the laptop.
• Disconnect the power adapter and remove the battery (if removable).
• Press and hold the power button for 15-20 seconds to discharge any residual power.
• Reconnect the battery and power adapter.
• Turn on the laptop and see if the battery is recognized.

Update BIOS

• Check if your laptop's BIOS is up to date. An outdated BIOS can cause battery detection issues.
• Visit the HP Support website to download and install the latest BIOS version for your laptop model.
• Follow the instructions provided on the HP website to update the BIOS.

Check Battery Health

• If the battery is detected but shows incorrect information or doesn't charge, it might be degraded.
• You can check the battery health using HP Support Assistant or by running a battery test in BIOS.
  • To run a battery test in BIOS: Restart the laptop and press F2 repeatedly during startup to enter the BIOS menu. Look for the Diagnostics section and select Battery Test.

I hope this helps.

Take care and have a good day.
