But if I press the light button the lamp bulb symbol comes up. If the button was misaligned then the software would not display the symbol, i.e. the event wouldn't occur, right?
Also, the corner of the bezel seems to sit very tight, just like the other three corners.
But do you suggest I take the cover out again and put it back? Any other suggestions? When I take it out, should I look out for anything strange?
UPDATE: checked that the tab is inside the red slider. Putting it back together again. Let's see.... No, still the same story: no light and the top-right corner of the screen is unresponsive.
