Many Macs get stuck when the PRAM battery is dead or dying. Some won't do anything, some will start but not boot (power on, spin up the drives, and just hang at the grey self test screen), some will boot but you will get no video... and some will just act plain wonky. On some Macs, there is a 'CUDA' switch (no idea what CUDA stands for... anyone know?). Its a little tiny push buttin switch on the logic board. Pressing that switch will do a deap PRAM reset, which will usually cure the dead battery issue (although if the battery doesn't get replaced, the issue will come back eventually). This can be done in place of removing the battery for 24 hours (but not all Macs have the CUDA switch, so some you are just stuck pulling the battery). -chris <http://www.mythtech.net>
