Sometimes I will shut down my macbook normally, and then a little while later I will go to turn it back on, but nothing happens. The light doesnt come on and the screen remains dark. The only way to get it to turn on is to actually remove the battery and then replace it. After doing this it will run fine. What could the problem be? It doesn't happen all the time, but it has happened twice in the last 24 hours. My macbook is only about 4 days old so it certainly hasn't been abused. Thanks for your help.
