My computer has both the lights on the keyboard and the power button lights ON when I open the lid. However, when I open the lid the screen remains blank with a black screen, until I press down the power button for a couple of seconds, the keyboard lights turn off, and then I press the power button again, and laptop turns on again. It's very annoying thing to do after every time I close the lid and computer goes into hibernation, and leaves lights on.
