Q: Macbook Sleeps randomly ?

My Macbook goes to sleep randomly and doesn't wake up even when restarted(The screen remains off) and usually wakes up after day or two. I've researched a lot and the only solution I could find was it's due to magnets around the laptop but I don't even have any kind of magnetic material around my macbook.

Please help me if you know other solution. Otherwise I was thinking of removing magnets or sensors from Display screen(which senses when the laptop is closed.)
