>when the PB goes to sleep, I can't wake it properly w/o rebooting >PB...all I get is blank screen...any clues???
I'm not sure what the fix for this is, but I remember reading something about this on O'Grady's PowerPage. Check 'em out (http://www.ogrady.com) and see if you find it there. Mac Fixit's also a good site for this sort of info.
