Does anyone know what's going on with my TiBook G4? (Specs are: 800 MHz/1 GB RAM/ 60 GB HD - running OS X. 10.2.4) After putting it to sleep, on occasion it will not wake when the lcd is opened and gives me a quick bright flashing lcd sleep indicator with an accompanying series of beeps. (almost like an SOS signal!) I have to hold down the power and restart. On two occasions I did this and got the familiar Mac start-up tone but the system did not boot? The system is babied traveling in a protected case from my home office desk to my office desktop, it's never been dropped or abused. Thanks Joe Fisher --
