Troubleshooting a Laptop that is Not Charging When Plugged

One of the best practices to care for a laptop and its battery is to charge it when it discharges up to the 20% level. But if plugging it into a power source does nothing, and it refuses to charge, that means there something wrong.

In some cases, people overreact on a situation like this triggering them to panic. However, if this happens, just be calm and think things through because it may only be caused by the simple issue.

If you find yourself in this situation, here’s what you can do to determine what’s wrong.

1. Check if There’s Something Wrong With the Connection

If a laptop doesn’t charge after plugging it into a power source or outlet, the first thing you have to check is the connection. Since it has something to do with power, focus your attention on the components involved in delivering it.

Double-check to if your power cord is actually connected with the power source, also make sure if the plug-in adapter is plugged into your laptop’s AC input dock. You can also inspect the wires or the cords of the charger.

Sometimes, the charger wires can be damaged if they are constantly curled up or accidentally stretched. Damaged wires can prevent the transfer of electricity and prevents the device from receiving the supplied power.

2. Take a Look at the Drivers and Update Them

Another thing that may cause a laptop’s battery not to charge is outdated drivers. Try to update your laptop’s drivers if it fixes the issue. Access your control panel by hitting the Windows button on your keyboard then select Control Panel.

Navigate to Hardware and Sound then click on Device Manager. On the Device Manager window, look for the Batteries item then expand it to show a dropdown list with two items. Right-click on the first item, Microsoft AC ADapter, and then select Update Driver.

Next, right-click on the second item, Microsoft ACPI-Compliant Control Method Battery, and then select Update Driver. After that, reboot the laptop and see if it addresses the issue of not charging.

3. Test the Battery and Check if It’s Dead

If the laptop refuses to charge, maybe it’s because the battery of the device is broken, damaged, or dead. To see if the battery is the reason for not charging and your unit has a removable battery, take it off once the battery is detached, press and hold the unit’s power button for at least 20 seconds to drain the remaining power within the device.

While the battery is detached, connect the laptop to an outlet, and then try to turn it on without its cell. This will give you an idea of whether the battery of your device is the one that causes the problem. If the device turns on, then you confirmed that you need a battery replacement.

Now, if you have a laptop that has a sealed battery pack, then that will be a more complex issue. However, the only thing that makes it complicated is because you will have an additional task of accessing the power pack.
