Battery charger not working?

Question

I have a Dell inspiron 1501 and my charger one morning just didn't want to work. The green light doesn't turn on anymore. Why is this, will is still work, and if it won't how can i prevent this in the future if i buy a new one?

Answer 1

It sounds like it's broken. All electronic things break sooner or later, they undergo electrical and thermal stress.

I keep a spare power supply for my laptop, in case it dies.
