If your laptop’s battery is not charging, there could be several possible causes. Before proceeding with any troubleshooting steps, make sure that the charger is correctly plugged into both the laptop and a power outlet. If the problem persists, then below are some potential causes and solutions to try.
1. Battery Malfunction
First, it is important to check the battery itself to ensure it is functioning properly. If the battery appears swollen or misshapen, it may need to be replaced. Some laptops have a reset pin or button on the battery itself; consult your user manual for instructions on how to reset it. If the battery does not seem to be having any physical issues, try uninstalling and reinstalling the battery driver from the device manager in Windows.
2. DC Jack Malfunction
Another possible cause of a laptop battery not charging could be a malfunction of the DC jack. This is where the charger plugs into the laptop. To test the jack, you will need a multimeter. Firstly, disconnect the laptop from the power supply and remove the battery. Then take the AC adapter and connect one of its pins to the positive side of the multimeter. Next, locate the DC jack on your laptop and measure the voltage using the negative end of the multimeter. It should read between 16-30 volts. If the voltage is lower or higher than this range, the jack may need to be replaced by a qualified technician.
3. Power Setting Issue
Sometimes, the issue may be due to a power setting conflict within the laptop’s operating system. Try changing the “power plan” in the control panel to “power saver” or “balanced” mode. Also, if you are using a USB port to charge, try disabling the “USB selective suspend” setting in the power options.
4. Faulty Adapter
In some cases, the issue may be due to a faulty adapter. Unplug the adapter from the wall outlet and laptop and check for any visible damage or debris. Also, try using a different power outlet as well as a different adapter.
5. Software Issues
Lastly, an issue may also be present in the software or device drivers. To fix this issue, try updating the laptop’s BIOS and all device drivers from the manufacturer’s website. You can also try resetting the laptop to factory settings or reinstalling the operating system.
By following these troubleshooting steps, you should able to determine the cause of your laptop battery not charging issue. If any of these solutions do not work, it is recommended that you contact customer support for assistance as further diagnosis or repair may be required.
