Lithium Ion or Li-ion batteries are the most commonly used batteries in laptops and other devices. Dell laptop batteries are designed specifically for each Dell laptop. If you are experiencing any of the following symptoms, the suggested quick steps might help.

CAUTION: Dell recommends using a compatible battery purchased from Dell that is designed to work with your Dell laptop. Using a third-party or non-Dell battery, or an incompatible battery may increase the risk of fire or explosion. Do not use a battery from other computers with your computer.

NOTE: If you see that the battery pack is swelling, Dell recommends discontinuing using the battery and replacing it with a Dell-authorized battery. To learn more, see the swollen battery information and guidance.

  • The laptop battery does not charge or does not hold a charge.
  • The ac adapter is plugged in but not charging the battery.
  • The battery is not recognized by the laptop.
  • The battery discharges quickly or does not last.
  • The battery charge is stuck at a certain percentage.
  • The battery indicator LED does not glow, blinks in a specific pattern, or blinks always.

Here are a few quick steps that you can try to resolve the battery issue

Try each step and check if the battery issue is resolved. If the issue is not resolved, proceed to the next step.

  1. Verify that there is no damage to the ac adapter, cables, or the power (DC) port on the laptop. Learn how to identify ac adapter damage on Dell laptops.
  2. Verify that the ac adapter is working correctly (the LED on the adapter brick or the plug must be turned on). If the ac adapter is not working, learn how to troubleshoot ac adapter issues on a Dell laptop.
  3. Always use the ac adapter that was shipped with the laptop. Dell does not recommend using incompatible or third-party ac adapters with Dell laptops.
  4. Connect the ac adapter to another wall outlet (bypass any surge protectors or power strips).
  5. Connect the ac adapter to the laptop. Bypass the docking station to check if the issue is caused by the docking station.
  6. Try to charge the battery with the laptop turned off. Several settings in the operating system such as power management settings and drivers may impact the performance of the battery.
  7. Check the battery health status. The battery health status determines if the battery requires a replacement. Learn how to improve the performance of a Dell laptop battery.
  8. Go to Dell.com/support/drivers, download and install the latest BIOS for your Dell computer. Learn about Dell BIOS updates.
  9. Run the SupportAssist diagnostics on the battery. If the test fails, contact Dell Technical Support.
