Try this, where the button is, there is an arm in the centre which goes to the power switch, raise it a little so there is a gap for a thin peice of card.....This works 100% for me, my button is now better than when I buy it, very sensitive to touch, only need to press power button lightly and it works
Exactly what I did. Took a couple of goes myself to get the snuggest fit, but persevere and it'll work. Was worried the back wasnt going
to fit at first though.
