I have an iphone case that charges it as well. i guess there was a short or something because the charging became sporadic. i plugged the usb into my computer over night and the next day when i booted up my computer it goes through the windows loading then instead of seeing my desktop i see a black screen. this is the same in safe mode. i've also rebuilt the system and i still get black screen. i'm puzzled cause i can get into and see my bios, and i see the windows loading, but when it comes to getting into the OS i get the black screen. any help is greatly appreciated. thanks!
