How to Resolve Battery Charging Problems

If your laptop's battery isn't charging or the battery won't hold charge, following these steps can help resolve common battery charging-related issues.

Checking the Power Connection

1. Ensure that the power outlet is working properly by plugging in another device.
2. Try plugging the charger into a different power outlet to rule out issues with the outlet.

If the laptop battery is still not charging, proceed to the next step.

Inspecting the Charger, Charging Port, and Cable

1. Inspect the charging port on your laptop for any debris, dust, or lint that could be obstructing the connection. Use compressed air to blow out any debris gently.
2. Inspect the entire length of the charging cable for damages such as frayed cables or bent pins. If there are any visible signs of wear or damage, replace the cable or charger.

If there are no damages, proceed to the next step.

Performing a Hard Reset

1. Turn off your laptop.
2. Disconnect the power adapter and remove the battery (if applicable).
3. Disconnect all peripherals, including external monitors and docking stations.
4. Press and hold the power button for 15-20 seconds.
5. Reconnect the battery (if applicable) and the power adapter, then turn on your laptop.

If battery still doesn't charge, proceed to the next step.

Reinstalling Battery Drivers

Sometimes, a corrupted driver in Windows may cause battery charging issues. Reinstalling the driver can often resolve these software-related battery issues.

1. Right-click on the Start button and select Device Manager.
2. Expand Batteries.
3. Right-click on Microsoft ACPI-Compliant Control Method Battery and select Uninstall device.
4. Restart your computer.
5. Windows automatically reinstalls the necessary drivers.

If the laptop battery stops charging, proceed to the next step.

Updating BIOS and Drivers

Outdated system drivers and BIOS are a common cause of battery charging issues. Updating drivers and BIOS ensure compatibility with the latest operating system updates and fixes known issues. SupportAssist is Dell's automated tool that scans your Windows computer for driver and firmware updates, downloads, and installs them.

1. Search for SupportAssist in the Start menu and open the app.
2. On the Home tab, select Update Software.
3. Click Start to check for driver and BIOS updates.
4. Follow the on-screen instructions to complete the installation and restart your computer if prompted.

If you don't have SupportAssist, refer to our driver update guide for alternative methods to download and install Dell drivers.

If updating drivers and BIOS didn't resolve the charging issues, proceed to the next step.

Running a Dell Battery Test

Dell laptops come with SupportAssist to scan your computer for hardware-related problems, including battery issues. To check for potential hardware issues with your battery:

1. Go to SupportAssist battery test. If SupportAssist isn't installed, follow the prompts to install the app if required.
2. Follow the on-screen instructions and respond to the prompts.
3. Once the diagnostic test is complete, SupportAssist displays the results.
4. If a hardware issue is detected, you may be guided to update drivers or contact Dell Technical Support for repair options.
