Hello Folks!my Colleague brought a aPad from his business trip. At first usage its works as it should. No problems.I've charged the device over night. At least 10hours.Today aPad isn't starting anymore. I see Tux in the left corner. After the small Andriod and after that the bigger Andriod writing. That's it. Black screen. No reaction when pressing any button.Does anyone have an idea, please?CheersSkulli
