This may or may not be related, I have had problems in waking up my cube numerous times.... Purely by empirical observation... ... if a previous system crash/error has occurred and I have NOT run Norton and fixed permissions it can take up to ten mins to wake up, if indeed it does wake up. Conversely if Norton has been run (disk doctor) and fix permissions the cube wakes up within 30 secs max. Educated guess, when the cube is attempting to wake from sleep the OS would look to access various files to refresh and update the screen, active memory and any application and or data changes...if they are "broke" endless loop of trying to access unable to access etc... Also another thought, the wake up can linked to the user data i.e. enter password on wakeup, if the user info is wrongly permissioned or the log file or something else prevents access, then maybe that is another avenue to explore If the disk and or permissions are suspect then either way they would not have access to, rights to, and/or the file/data location is corrupt or the process the OS is trying to execute is not viable. It has to be a fundamentally simple issue that creates a moebius style error Just my 2 penith' worth John Guy Feel free to shoot these thoughts down in flames as long as you have a better explanation. I.e. Lets fix/identify the problem rather than argue who we should be waggling our fingers at... JG >> >> So here's what we know: some stock Apple machines have sleep problems.
