How to change the battery.

Hi,

If you have a Lenovo Ideapad 110-15AST as you have selected in your question, then here’s the hardware maintenance manual.

Go to p.35 to view the necessary pre-requisite steps and then the procedure to remove replace the battery pack.

On p.64 Item #12 you will find the part numbers for the battery. If you search online using only the part number, appropriate to your model laptop, you will get results for suppliers of the part.

If you don’t have the model mentioned then the information in the hardware manual may not be applicable to your particular model as they are not all necessarily the same.
