Battery or battery charger not working - how do I know which one?

[ItsTheOnlyWayToLive]

I have a Samsung laptop R530.

The symbol on my laptop shows that the battery isn't actively charging. Then, every now and again for a very few seconds, it starts charging.... then stops again. Obviously I cannot run it without having to plug the charger in. Is it the battery or the charger?

I don't want to fork out for a battery only to find out its the charger.

Sorry, excuse my manners, many thanks in advance

Probably battery. Mine got very weak after a few years.

I'd say it's the charger. Every laptop that I've had this problem with its always been the charger. Can you borrow a charger from someone and see if it works?

Unfortunately not, viva. Everyone else I know has a different make. Thanks anyway

I have the same laptop on my 3rd charger now, take the battery out and plug the charger into the laptop see if it works, if it doesn't its the charger.
