  (Asked by: username_0 on 2015-09-26)
  
  I just can not turn on the EV3 with the SD card. I only turned on it twice.
  The EV3 stops at [-leJOS EV3] UI and does not go to the next step.
  
  I charged the battery, reinstalled the software inside of the SD card, changed the EV3 for one time, reset the EV3, but I still cannot turn it on.
  
  I can only turn it on without the SD card.
  
  How can I fix the problem?
