I am wondering if anyone has every experienced this problem. Whenever I place my Powerbook 12" (867Mhz model w/ combo drive) on a flat surface I get some weird results. When I am working on the powerbook on a table it starts beeping as if a key is being depressed, which of course it's not. If I move the mouse around or click on something it starts switching windows in and out of the foreground, not sure what key causes this to happen but I assume thats the one acting as if it's being held down. The funny thing is if I use the powerbook on my lap or have it on an angle on the table it doesn't exhibit the problem. Has anyone ever experienced this? If so, what was the fix. I don't have applecare and if I can fix it myself or at least have an idea what it may cost that would be great. Any advice would be appreciated. Thanks!
