[Ti] Is there a battery on the TiBook motherboard?

[John R McDaniel]

I have a trusty old 1st generation Ti/500.

Lately, if I shut down it will not boot up until I use the reset button 
on the back.

It tries to boot; the hard drive spins up & I hear the familiar chime, 
but nothing else happens --no screen --nothing.

Is there a motherboard battery like the desktop units have? Does it 
need replacing after this amount of time?

A little while back I had a problem with an intermittent short in my 
power supply that seemed to scramble the PMU. After a great deal of 
work (and symptoms like the above) I got the TiBook to come back to 
life. Now I seem to be backtracking to earlier problems.

Ideas?
