Hello people! Well, I've had my powerbook now for about 6 weeks and about a week ago I noticed that about 30% of the screen in the lower right corner appears to quite dark when I first boot up. It seems to sort it self out after about 30 minutes of being on, but it's very noticable when I first switch the PB on. LIke I said I've only noticed it within the past week, so does anyone have any idea what it could be due to? is my Powerbook faulty? Thanks - Phil!
