The issue can also be with the charging port. Examine your laptop charging port. If it is dirty, clean it carefully. Also, make sure that the charging port is not damaged.
4] Try another charger
We also suggest you connect another charger (if available). Also, the charger should be of the same laptop brand. This will let you know whether the problem is associated with your charger or not. If your laptop does not make a beep sound after connecting another charger, you should replace your current charger. But wait, the problem can also be with your charger cord or adapter.
Laptops of some brands have dedicated software to test the adapter of the charger. Open the dedicated app or software based on your laptop brand and check if this feature is available. If yes, test the adapter.
For example, the MyASUS app allows users to test the health of the adapter. If you are an ASUS laptop user, open the MyASUS app and select System Diagnostics from the left side. Select the Adapter checkbox and click on the Checkup button. Connect your charger and turn on the power supply before performing this test. You can view the result in the Diagnostic History tab.
5] Decode the beep sound
Motherboard makes a beep sound when a hardware issue is detected. Motherboards of different brands indicate different hardware issues with different beep sounds. These beep sounds are called Beep Codes. Based on your laptop or motherboard manufacturer, you can decode the beep code to know the exact hardware issue.
6] Run a battery test
We also suggest you run a battery test to know if your laptop battery has malfunctioned. For this, you can install the best free battery test software. Or, you can use the dedicated software developed by your computer manufacturer, provided it has a feature to test the battery’s health. Some popular software include:
7] Update or reset the BIOS
If the problem still persists, update your laptop BIOS. Go to the official website of your laptop manufacturer and check if an update for the BIOS is available. If yes, download the update and install it.
You can also perform a BIOS reset and see if it helps.
8] Disable Realtek HD Audio Manager
If your laptop has Realtek Audio Manager, disabling it can help. You can check this in the Volume Mixer or Sound Mixer options. Click on the Windows Search and type Volume Mixer or Sound Mixer. Select the matching result.
When the Volume Mixer opens up, disable the Realtek Audio Manager (if it is available there). Before you disable it, make sure that you have performed all the above-mentioned fixes and that you are not experiencing issues related to your laptop battery or charger.
10] The motherboard might be faulty
