My Iphone 4 don't open anymore

My IPhone 4 wont turn on.
I have tried holding both buttons in & tried connecting to laptop whilst holding down the home button but still nothing!!

Possible solutions:
1. Try plugging it in
While its plugged in try holding the lock button down and 2 second later hold the home button down while still holding the lock button down
2. Try charging it for 2 hours, if it doesn't hold a charge then something is wrong with the battery.  Call apple and ask to set up a repair. The battery is in the warranty and they should set you up with a replacement phone.
