I have a Titanium that is currently without battery as I plan to buy a new one. I notice that if I power the machine off and have it unplugged for a day or so, the next time I start up and login I get a warning about the clock being set to before 2001. It is set to 12/31/69 7:00pm. I would think that there is an internal BIOS battery that would keep this going -- am I mistaken? -- Justin R.
