Black screen, sleep/wake button broken

[lolada]

Hi, I have a problem with my iphone ios 7.0.1 (or 7.0.2, I am not sure). My iphone just dont boot, when I plug it in my PC, it does not recognize the iphone, not even the usb conection. The screen is black all the time and I have not found any way to fix that.
I do not know what to do, since my sleep/wake button is broken I can not reset the iphone...
Please help me!
Ps: The battery is almost dead(I think) since its been 3 days with this problem already.

If your device is still under warranty you can bring it to Apple and they'll replace or repair it for you. If not, then you'd most likely have to take it apart and replace the battery and/or digitizer

The only part that is broken is the sleep/wake button, my iphone 4 is in a DFU mode or some other mode.
My battery is already dead so i am going to try to charge it now.
