My mac turns the display on by itself
After a few minutes when I turn the display off (brightness to zero), my mac starts to turn the display on by itself several times (with some interval). This happens every time when I turn the display off. This is strange, inconvenient and irritative thing. Do you know how to solve it? Thanks!
