A small number of the all-in-one desktops have been making a popping noise at start-up. Then, rather than turn on, the screen stays dark, Apple said on its Web site. In the posting, Apple says anyone experiencing the problem should contact a local Apple-authorized repair shop.
An Apple representative confirmed the issue has shown up in a "very small" number of eMacs, but would not say just how many or when the problem first cropped up.
The Mac maker has changed its manufacturing process to eliminate the problem, the representative said.
The eMac was introduced for the education market in April, and Apple started selling the machine more broadly in June.
