Repair dead HTC Innovation! Whats wrong with him! [Pass the Exam school :/]

[pl_laszlo]

Fuck*d Credit Exam!
Hello, my teacher gave me HTC Innovation to repair under the pass the exam but I do not know fully what it is. I do not have a charger only, a flimsy wire USB. Unless the battery is completely discharged because they do not respond to the inclusion. Does not respond to reset or command the entrance to the bootloader (camera + on / off + reset at the same time)
computer does not recognize it when connected via USB! Is he charging batteries by linking to a PC?
I greet and I count on your help!
Sorry for my English, translated by Google Translate from the Polish language.

Hi!

Please post a model number,for example: PM200,Pm20A it is Charmer.
You can revive the battery with a bit higher voltage(you can use a 9V battery,I use regulated power supply,BE CAREFUL WITH POLARITY!),I think you can find the battery pinout on this forum.After you have a loaded battery,you can check the phone and we can continue,if it needed.
