If your laptop is plugged in but not charging, these steps can help you troubleshoot.
1.Unplug for a few minutes, then try a different outlet.
Unplug the laptop, wait a few minutes, then plug it into an outlet in a different room. Some users report that a laptop power adapter can temporarily stop working to protect itself from a perceived issue with the power supply.
2.Let the computer cool down.
If your laptop battery feels very hot to the touch, excess heat could be interfering with the charging process.Shut down the computer and let it sit for several minutes to cool down.
3.Check Your Settings
In the Control Panel, open up the Power Options. Open the plan settings and visually check that all are properly set. Be on the lookout for incorrect settings for the battery, display, and sleep options. For example, your battery settings may cause trouble if you set the computer to shut down when the battery level drops too low or set the low battery level at too high a percentage.
4.Start up your laptop without a battery
A simple way to check the integrity of the battery is to remove it entirely and try plugging in the laptop. If the laptop powers on properly, the problem is likely a bum battery.
5 .Replace the charger
Sometimes the adapter (the box in the cord) is faulty, or despite your best efforts you can’t repair a loose plug. Try borrowing a friend’s charger, or asking an computer store employee to test your charger. If your charger is faulty, buy a new part from a computer or electronics store
