Are you facing issues with your laptop battery not charging? Don’t worry, this is a common problem faced by many laptop users. The culprit for this problem could be a bad AC adapter. In this article, we will discuss the steps to identify and fix laptop battery not charging issues caused by a bad AC adapter.

Step 1: Check the adapter connection
The first step is to ensure that the adapter is properly connected to your laptop. Check the adapter cable for any damages or wear and tear. Also, check if the adapter connector is properly inserted into the laptop charging port. If the connector is loose or damaged, it can cause charging issues.

Step 2: Check the adapter voltage
The next step is to check the voltage of the adapter. Most laptop adapters have a voltage output of 19V or 20V. You can check the voltage output of the adapter using a multimeter. If the voltage output is less than the required voltage, it can cause charging issues.

Step 3: Check the adapter for damages
Inspect the adapter for any physical damages such as cracks, dents, or exposed wires. Damages to the adapter can cause a short circuit and prevent the laptop from charging.

Step 4: Test the laptop battery
Remove the laptop battery and test it using a battery tester. If the battery is working fine, it could be a problem with the adapter.

Step 5: Replace the AC adapter
If the above steps do not solve the issue, the problem could be a faulty AC adapter. In this case, replace the adapter with a genuine and compatible adapter. Using a non-genuine adapter can cause damage to the laptop and battery.

Conclusion:
A bad AC adapter is one of the common causes of laptop battery not charging issues. By following the above steps, you can identify and fix the problem. It is important to use a genuine and compatible AC adapter to ensure the longevity of your laptop and battery.
