back up battery dead?

I have a white macbook core2 duo. The main battery is dead and I have been using it with the power brick. Lately when I plug in and start up I have to go through the reset time and date etc. I have heard that some of the newer laptops don't have the back up battery. Does this one, and how do I get to it to change it?

Many new designs tap the laptop battery for backup and clock

That's all in an effort to reduce costs and improve reliability. Less parts in any design equals more reliability.

Since your laptop is in need of repair, it may be time to get it fixed.

If you remove the power adapter

after you have shut down the computer, you will lose your date and time.

I believe there is a small capacitor that will allow you to change out batteries without loss of things like that but it is only designed to run for enough time to remove and replace a battery.

back-up battery

Thanks for the replies and info, but does this unit have a backup battery?

I'm going with no.

The prior G4 models did have one. The new models use the new design to curb costs, increase reliability and save a little internal space.
