Does a Macbook Pro (2007) have a seperate reserve battery?

I have one of the first intel based Macbook Pros (late 2007 ish).

If I get down to reserve battery levels the computer is basically unuseable. If the battery is dead, I can't really use the machine until it's battery climbs above reserve battery levels (about 8% charge or so).

Just wondering if the reserve battery is party of the main battery or if it's own seperate battery.

Anyone know?

Thanks,

In this context, there is only one battery in your computer and reserve would mean the last bit of remaining power. Battery life will shorten with age and number of charges. If you are still getting an hour or so out of this battery you could buy a second battery and use this one as a backup.

You an check the health of your battery by pulling down the Apple Menu to About this Mac and clicking on More Info. Then expand the Hardware Tab and click on Power.

Yea, but it's only the reserve battery that has issues... once it gets out of reserve battery territory the computer works perfectly.

Makes me think that it's a separate hardware battery... or separate part of the main battery

Also try resetting the SMU:

Thanks, I just wanted to know if there is a seperate piece of hardware for the reserve battery. It looks like there is from what strung posted.

Now if I sell the laptop I can tell the purchaser that the reserve battery has issues and needs to get above 8% or so before being used or can be replaced.
