Apple said on Friday that it is looking into the problem. More than 650 individuals have signed an online petition demanding that the Cupertino, California-based company address the issue.
According to postings on Apple's online user forum, many PowerBook owners have experienced the problem, which causes white markings to appear on the laptop's screen. By most of these accounts, the spots are less than one inch in diameter. However, some people reported seeing multiple spots on their computers.
Complaints about the problem have been cropping up on several Apple enthusiast sites in recent days.
In response, the Mac maker issued the following statement Friday: "The new 15-inch PowerBook has been a big hit with customers since its introduction last month. However, some customers are reporting the appearance of faint white spots on their displays after using the system for a short period of time, and Apple is investigating these reports right now. Any customers experiencing this problem should contact AppleCare."
Apple introduced the high-end 15-inch PowerBook in September. At that time, Apple CEO Steve Jobs said the device "sets the bar for professional notebooks even higher." The computer features a 15.2-inch (diagonal) widescreen display with 1280-by-854-pixel resolution.
Shortly after the notebook computers were released, going by the timing of the user group postings, PowerBook owners began sending messages to Apple's support site, trying to find an explanation for the spots.
Some users reported that they had noticed the distracting flaw immediately upon turning on the new computers, while others said the spots materialised over time. Some PowerBook buyers said they first saw the spots after getting machines back from Apple that had been returned for other repairs.
One explanation of what could be causing the spots was posted to the computer maker's Web site by a self-identified "Apple technician," who claimed to have taken apart his PowerBook to investigate the problem. According to that posting, the notebook incorporates several spacers behind its LCD screen that could be putting pressure on the display and causing the white spots to appear. The posting said the spacers were utilised in the PowerBook's design in order to keep the computer's aluminum casing from bending.












I purchased a 1.25ghz aluminum powerbook and just 2 days later the spots appeared on my screen. I have 5 inch size circles and what looks like an outline of a square in the middle of my screen. I use this machine for graphic design and this really bugs me because it gets in the way of my work. I hope apple does something about this quick!!
side note. I am getting it replaced by apple this next week but I'm sure that the spots will appear again on my new display :(
