Q: MacBook won't switch on

HI guys.

I Have an old 2008 White MacBook 2.4ghz.

I have only used it for a DJ set up for the past year with minimal software on it.

I Went to power it up today and it has no life.

It won't run on battery or connected to the mains.

I've tried two chargers. The battery was replaced about two years ago.

Any ideas??
