awake with lid closed
Authored by: johnsawyercjs on Dec 26, '08 09:49:20PM

Speaking as a Mac repair tech since before the first Powerbook: yes, lots of heat is dissipated through the keyboard, but never enough to warp the display. For one thing, the display contains a glass sheet, and a metal frame, and those aren't going to warp. There's also some relatively soft plastic in the LCD display's frame, but the metal frame and the glass sheet prevent that plastic from warping. There's a remote, theoretical possibility that if a Mac portable were to get ESPECIALLY hot for some reason (like the battery overheating, like a rare few do), the heat might go up through the keyboard and cook the LCD, causing it some damage like discoloration of the displayed colors, but it's very unlikely, and I've never heard of it happening.
