This post is currently up on MacFixIt: 'There have been a number of complaints of white spots on the displays of the new PowerBook G4 15" (FireWire 800). MacFixIt reader Alwi Yunus writes: "I've had the problem occur on my PowerBook purchased the day after the release at the retail AppleStore in Newark NJ. I had the screen replaced back home in Malaysia but five days after the screen replacement, the spots are back in the exact same configuration and place. I'm convinced that the problem does not arise from the screen itself but from the bottom half of the clamshell - from heat generated by the bottom half of the powerbook damaging the display when the powerbook is closed. That is the only explanation I can think of for the problem recurring in the exact location of the original spots. I've put up pictures of my PowerBook at <http://homepage.mac.com/alwi/PhotoAlbum10.html>"'.
About a month or so ago a single white spot appeared on the screen of my now 16 month old iBook (roughly in the position of the one on the left of the screens in Alwi's pictures). Anyone else seen this on either their existing iBook or TiBook? I'm covered by AppleCare but probably won't bother using it at this stage ... I'll see if the problem gets worse. Alwi's heat explanation sounds plausible. Until recently I lived in a caravan and in summer the iBook fan was always on during the daytime when the external temperature was 38 degrees Celsius or above (God knows what the temperature was in the van but it was HOT!). So my screen was subjected to some high temperates upon closure during the course of last summer. --- Richard Kay Fremantle Western Australia
