Hi,
- Which operating system is installed on the computer?
- What is the make and model of the laptop?
- Does the battery gets charged when laptop is shutdown?
I would suggest you to see the laptop manual to enable battery charging option. If you are using Dell Laptop, then you can try the following steps.
a. Insert your Dell laptop battery into the battery compartment on the bottom of your computer's case. The battery will snap into place.
b. Plug your Dell laptop battery charger into a wall outlet.
c. Insert the opposite end of your Dell laptop battery charger into the charger input on the side of the computer.
d. Turn on your Dell computer and allow it to boot into the Windows operating system.
e. Tap both the Fn key and the key on your keyboard that you need to tap to enable battery charging on your model of Dell laptop computer. For example, on a Dell Inspiron 1525 you need to press the Fn and F2 keys to enable battery charging, whereas on a Mini 9 you need to press the Fn and 3 keys. This will change depending on what model of Dell you own, so look for the key that has an image of a laptop battery. This is the key you need to press. Battery charging is now enabled.
