If the battery was empty, you did recharge it before reinstalling it didn't you?
Yes I did recharge the Battery prior to test it again.

Is the grip a Canon grip or a third party? Are all of the batteries Canon or third party?
The Grip is thirdparty from Phottix Modellnumber BG-550D. One Battery is Canon the other is a third party one from KingMa. Meanwhile I found, when I charge both Batteries only the one from KingMa is letting me turning on the Camera.

Most of the grips for the 650D (T4i) has a device to use (6) AA batteries. Test it with "fresh" AA's and if it works it is likely time to replace the recharageable battery.
I will check that, but I first need to buy some batteries.

May sound silly but if you press 'menu' does any menu load up? I ask as I did see someone who thought their camera was not turning on but actually the sensor above the screen was dirty and thinking there was someone looking through the viewfinder and so keeping the screen from turning on.

Also what John said about trying some AA batteries if you can as it may just be a dodgy battery.
Will do that tomorrow, need to buy some first.

A couple thoughts
press the info button to make sure you are not just looking at a black screen
The Problem is. After entering the KingMa Battery it works. As soon as I change the SDHC Card, the Camera is black even after pressing buttons. I need to eject an reinstall the battery first.

check the micro switch at the bottom of the battery door
like others said, try a freshly charged battery.
I can't find any switch there.
The thing is I bought this camera in September in Shanghai, while I was living there. And I can't find the cheque anymore.
thanks winam!
