What happens when the CMOS battery dies and which iBooks have it?

[Ariii]

The question pretty much explains the whole thing.

 

[Intell]

iBooks don't have a CMOS or PRAM battery. They use the main battery and a small capactior on the logicboard to keep the time. When it runs out of power, the clock gets reset to 1969.

the capacitator holds not more than 30 minutes. that will give enough time to swap batteries, or put the iBook on charge.
