Normally,the battery can not charge that is caused by such reasons:
1. Poor power management.
You should have a device manager in your machine to see what processes are taking place on your laptop. If unnecessary processes are going on, then stop them immediately. This will help in reducing power usage. There is software called Power Manager in most of the recent operating systems.
2.The screen brightness.
Many people like to use the computer in the dark because it helps them read better. In the case of the laptop, the monitor brightness makes it possible for the power to drain even faster. To reduce the use of the power, turn down the monitor brightness. If you use the laptop in a room with low light, then use a bulb or get sunglasses to protect your eyes.
3.The incomplete installation of the accessories
When you are installing an accessory such as a battery, make sure that you install it correctly. Do not install it on the plug that is backward. This will prevent the power supply from being damaged. If you are not sure about the position of the plug, ask for assistance from customer care.
4.The overuse of the adapter.
Many people use the USB to Ethernet adapter even when there is an available USB port in the laptop. These devices can only be detected when they are turned on. Hence, they do not use any energy when they are turned on. This results in the laptop not using enough power when you want to connect to the internet.
