As a matter of interest if anybody wants to change a battery in this model there is a catch to pulling it apart. At first instance you feel the cover slips on, beware if you try to push a thin blade between the plastic housing and the mechanics you will crack the glass and further " touch" will be useless. Here is the trick, peel off the black plastic surround that goes around the screen. You only have to do the corners as there are 4 little screws in the corner that releases the works. Lift it out by the side opposite the usb connections as they slip into the housing. And good luck with the battery!!
