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. See the suggested quick steps below if you are experiencing any of the following symptoms.
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 article.
When there is damage to the wiring of your AC power adapter, it can cause a short, which can damage your computer or fail, leaving you without a means to charge your battery. Look for frayed cables (Figure 1), exposed wires (Figure 2), a cut in the cable (Figure 3), or a pin that is bent or broken (Figure 4).
For more information, see Dell Knowledge Base article How to Identify AC Adapter Damage on Dell Systems.

Dell AC power adapters have a LED light to indicate whether the AC adapter is getting power and is on. The LED light may be on either the AC adapter brick or the adapter (DC) plug.
If the LED light is not on, perform the following steps to help resolve the issue.
For more information, see our AC Power Adapter Help and Support site.
The AC adapter that came with your computer provides the correct voltage and amperage needed to work correctly. Ensure you are using the AC adapter shipped with your computer or another of the same model.
Dell does not recommend using incompatible or third-party AC adapters with Dell laptops.
When the computer seems to be taking longer than normal to charge the battery, it may be due to a poor connection.
Perform the following steps to help resolve the issue.
NOTE: When there is a difference in charging it may be the surge protector or something interfering with the outlet making good contact.
Another poor connection could be caused by your docking station if you are using one.
Plug the DC power cord directly into the laptop, bypassing the docking station to see if the battery charges quicker and the computer works better.
Several settings in the operating system, such as power management settings and drivers, may impact the battery’s performance.
Checking the health of your battery will tell you if the battery is working correctly and helps identify if an aging battery requires a replacement.
