Feasibility of running a laptop on its battery charger

Is your laptop battery dead and you are wondering if you can run your laptop just with the help of your laptop adapter? Know the answer to this question from our experts.

I am having an old Apple Macbook laptop. Its battery has gone dead and not picking up charging. I am in a process of getting a new battery which would take time. Meanwhile I tried to use it on the mains using its battery charger. It is working fine but the device is heating more than when its battery was good. Can someone suggest or advise whether we can use the laptop on mains using the battery charger of the device or not. Is there any implication?
