Several owners of the new 15-inch aluminum PowerBooks are having problems with “mysterious white blotches” showing up on the LCD screens, according to a San Jose Mercury News article.
Some posts on the Apple message boards indicate that, in many cases, the spots appeared gradually over several days; others said the spots were visible the first time they turned on the PowerBook. Some customers on the discussion board said they sent their laptops in for repair, but the spots reappeared when the systems came back, the Mercury News reports.
This week the Apple message boards included a post from a person who identified himself as an Apple technician. He said that the white spots were showing up in the places where spacers were located behind the LCD screen to keep the aluminum casing from bending in, the article says.
“The new 15-inch PowerBook has been a big hit with customers since its introduction last month,” Apple said in a statement released on Thursday. “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.”
