My iBook 1.42ghz seven weeks old now, likes to go to sleep after I'm using it and then, when I try to wake her up, it takes slapping the space bar two or three times before she snaps out of her nap. Today, she will go right back to a black screen for a second until I press space bar again and again and then she wakes up. Is this normal? I'm not that well versed in how and why i should be keeping her in sleep mode in the first place, but sometimes I just keep her on when I go out and she goes to sleep. I'm always suspicious of her Fujistu hard drive - - tho that probably has nothing to do with it. If I had known it was a Fujistu hd I would not have picked this machine for purchase. Anyway, should this iBook take that much space bar action to wake up from a deep sleep?
