How can get my iPhone 4s to turn back on?

[iMore Question]

Both the phone's power and home buttons do not work, and it has been on the charger for almost a whole day. It wont come back on.

... Captain Obvious says get those fixed, or replace the phone...

I am utterly amazed at the amount of iPhone 4 & 4S devices that somehow fail to power on for owners who allegedly have non-working power and home buttons. It's unbelievable....
