To ensure that the Dell battery is getting charged correctly, the ac adapter must be working correctly. Verify that the laptop can recognize the ac adapter.

To verify that the laptop is recognizing the ac adapter correctly:

1. Restart the computer.
2. At the Dell logo appears, tap the F2 key several times until the message Entering Setup appears.
3. Verify the AC Adapter Type in the BIOS options.
   • If the ac adapter type is None - Verify that the ac adapter is connected to the laptop and the wall outlet.
   • If the ac adapter type is Unknown - See the Dell knowledge base article How to Troubleshoot AC Adapter Issues on a Dell Laptop.
   • If the ac adapter type is recognized correctly, proceed to the next step.

There are several settings in the operating system like power management settings, device drivers, and so on, that may impact the performance of the battery. Charging the laptop battery outside the operating system (when the laptop is powered off) helps isolate hardware-related issues.

1. Turn off the computer.
2. Try one of the following combinations:
   • When the laptop is turned off, charge the battery for some time.
   • Or, restart the laptop and tap the F2 key to enter the BIOS or System Setup. Allow the battery to charge.
3. Verify if the battery charge percentage has increased.
4. Restart the computer, and proceed to the next step.

Running a hardware diagnostic test helps identify what the issue may be and provide you with troubleshooting steps to help resolve the issue. Dell offers both built-in and online diagnostics. It is essential to run a hardware test on the laptop and/or the battery to identify which device is causing the issue.

To run an online hardware test on the battery using Dell SupportAssist, browse to the battery diagnostics page.

To run the Dell Pre-Boot System Assessment test:

1. Turn on the computer.
2. At the Dell logo screen, tap the F12 key several times until the One Time Boot Menu appears.
3. Use the arrow keys on the keyboard to select Diagnostics and press the Enter key.
4. Follow the on-screen prompts and respond appropriately to complete the diagnostics.
   1. If the test passes, proceed to the next step.
   2. If the test fails, ensure to write down the error code and validation code, and contact Dell Technical Support.

Checking the battery health status helps determine if the battery is operating normally or if it needs to be replaced. Battery health status can be checked both inside and outside the operating system. See the Dell knowledge base article How to Check Battery Health Status on Dell Laptops.

If the battery health status is normal, proceed to the next step.

The BIOS is firmware that is embedded onto the system board (motherboard) of the computer. Updating the BIOS to the latest version helps the computer recognize the ac adapter correctly. Updating the BIOS to the latest version requires the laptop to be powered by the ac adapter and battery.

If the ac adapter type is not recognized by the laptop, see the Dell knowledge base article Forcing a BIOS Update without the AC adapter attached on a Dell Laptop. Before trying to force the BIOS update, read the disclaimer below.
