A little more information on your system and OS may be helpful.

When you are having problems it never hurts to zap the Pram (but you may
need to reset a couple of things afterward), re-build the desktop, and run
Disk First Aid.

How far do you get on startup? Do any of the extensions load? What happens
when you restart after locking up? What happens if you try starting up
manually (instead of scheduling)?

As far as the battery is concerned, I understand some Macs have problems
booting with a bad battery. I work with a couple of 5400s and a Performa
575 with dead batteries. As long as they are connected to a funtioning
outlet, you would never know about their battery. If you lose power, unplug
them, or turn off their power switch then you lose settings such as
date/time and AppleTalk. That's a minor annoyance  on the 5400, but the 575
(which has some external SCSI devices) sometimes has to be restarted a
couple of times to get back in sync with everything. You might want to
