Show all | Hide all Verify AC adapter functionality 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. NOTE: Dell Technologies recommends using the original AC adapter that was shipped with the laptop. NOTE: Ensure that the AC adapter that is connected to the computer meets the minimum wattage that is required for the computer to charge the battery. Many high-end computers require higher capacity AC adapters such as 150 W, 180 W, 210 W AC adapters. NOTE: Dell laptops docked to E_Port series, or other docking stations must use the AC adapter that was shipped with the docking station. These AC adapters have a higher capacity that is based on the additional power requirements of the docking station. To verify that the laptop is recognizing the AC adapter correctly: Restart the computer.At the Dell logo appears, tap the F2 key several times until the message Entering Setup appears.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. This is often caused when the AC adapter is not working or if the laptop cannot detect the AC adapter.If the AC adapter type is Unknown - See the Dell knowledge base article How to Troubleshoot AC Adapter Issues on a Dell Laptop. This is often caused when an incorrect or faulty AC adapter is connected to the laptop.If the AC adapter type is recognized correctly, go to the next step. Charge the battery in BIOS mode or with the laptop turned off There are several settings in the operating system like power management settings, device drivers that may impact the performance of the battery. Charging the laptop battery outside the operating system (when the laptop is turned off) helps isolate hardware-related issues. Turn off the computer.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. Verify if the battery charge percentage has increased.Restart the computer, and go to the next step to run a hardware diagnostic test. Run the Dell hardware diagnostic test 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 integrated and online diagnostics. It is essential to run a hardware test on the laptop 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. NOTE: Running an online hardware diagnostic test on the laptop requires you to download and install the Dell SupportAssist application. To run the Dell Pre-Boot System Assessment test: Turn on the computer.At the Dell logo screen, tap the F12 key several times until the One Time Boot Menu appears.Use the arrow keys on the keyboard to select Diagnostics and press the Enter key.Follow the on-screen prompts and respond appropriately to complete the diagnostics. If the test passes, go to the next step.If the test fails, ensure to write down the error code and validation code, and contact Dell Technical Support. Check the battery health status Checking the battery health status helps determine if the battery is operating correctly or if it must 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. NOTE: The number of charge and discharge cycles determines battery life. This is also due to the consumable components inside a battery.Battery capacity is the amount of time the laptop can run on a fully charged battery. It is normal for all types of batteries to lose some battery capacity and battery life over time. Every time a battery is charged or discharged; the battery loses a small amount of battery capacity. This behavior is considered a normal characteristic of a rechargeable battery, and the warranty does not cover this.For more information, browse to the Dell knowledge base article Dell Laptop Battery - Frequently Asked Questions. See What are the guidelines for handling worn-out and swollen batteries, and then replacing the battery on a Dell laptop? section.For more information about swollen battery, see the Dell knowledge base article Swollen Battery Information and Guidance. If the battery health status is normal, go to the next step. Update the BIOS and Dell Quickset 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 AC adapter and battery to be powering the computer. WARNING: Dell laptops must have their battery that is installed and connected to the AC adapter before you begin to update the BIOS. Some Dell laptops must have at least a 10% battery charge before you begin the BIOS update. To update the BIOS to the latest version, see the Dell knowledge base article Dell BIOS Updates. If the computer does not recognize the AC adapter type, reference the Dell knowledge base article Forcing a BIOS Update without the AC adapter that is attached on a Dell Laptop. Before trying to force the BIOS update, read the disclaimer below. CAUTION: If the battery charge is less than 10%, you may be able to force the BIOS to update from within the DOS environment. A failure during this process can damage the system board of the computer. Users must proceed at their own risk. Dell shall not be liable for any loss, including but not limited to loss of data, loss of profit, or loss of revenue, which customers may incur by following any procedure or advice set out in this article.
