Hello: It's been ages since I've had to post a hardware/software issue: I love my chosen platform... BUT: Since I installed the 10.3.8 update my PB 867/640 RAM/40 G HD/Combo Drive has been exhibiting a weird problem: at least once a day, when I open the lid to wake it from sleep, the keyboard and trackpad are completely unresponsive: the machine seems to function normally otherwise, since it keeps track of time: I just can't place any input at all. My USB and Apple wireless mouse and keyboard are equally uneffective: but the clock keeps ticking which makes me believe that the machine is operating normally save for not letting me input anything. The only thing I can do is hold down the power button, wait for the shut down, then run fsck -f (it's running Panther of course) at restart. Of course, the resulting test yields no errors. Has anuone else experienced the same on Rev. A 12" PowerBooks? Should I revert to 10.3.7? Everything seems to work except built-in input devices... What is going on? Normally I do not post at Apple forums... should I try this out there?
