iBooks don't have a PRAM battery (PowerBooks do, but not iBooks I 
believe).  I can think of three possible causes:

1.  Fried logic board.  Not very likely, and not much you can do 
about it other than fork up big bucks for a replacement.

2.  More likely - messed up power manager chip.  You can reset this - 
you'll have to look at the Apple Support web site to get the 
instructions on how to perform a reset for her specific iBook model - 
the instructions are slightly different for different models.  You 
can also try a reset in Open Firmware - power up the iBook and 
immediately hold down the command, option, and O (oh, not zero) and F 
keys until the screen lights up and dumps you into an icky Open 
Firmware command line environment.  Try these commands (without the 
quotes) - press return after each command - "reset-nvram" - 
"set-defaults" - "reset-all".  The last command should cause the 
iBook to reboot and hopefully everything will now be squared away. 
You'll need to set the clock once more, but it might now start 
keeping the time correctly.

3. Still more likely, since you mention it is an older iBook - the 
rechargeable battery is shot.  With the best of treatment, they'll 
still last only about 4-5 years tops.  If you don't have the iBook 
plugged in and the main battery is dead, there isn't anyplace to get 
power to run the clock, since there isn't an internal PRAM/clock 
battery.  Solution: keep it plugged in or get a new main battery (be 
ready to spend moderate bucks).

If she has internet access that doesn't use dial up, there is also a 
gross nasty icky (but free!) work-around under OS X - go into the 
date-and-time system preference panel and turn on "set date and time 
automatically".  Then every time the iBook boots up, it will reach 
out into the net and reset its own clock to match the time from the 
network.  Since this happens at startup, it will look like the clock 
kept the right time and all will be well with the world.

Hope this helps.....
