Power source: Power Adapter even when not plugged in
My 13" Macbook (Late 2008 Version) says that the power source is the power adapter even when it is not plugged in. Because of this it will not switch to the energy saver options for when it is running off of the batter as opposed to being plugged in. Why is it doing this? I have tried resetting the SMC and that has not worked.
MacBook, OS X Yosemite (10.10.2), Late 2008 Version
