Hi guys
I have a used macbook pro 15" with the intel 2.5 dual core processor which may have been made in 2008 according to an app i ran. It is running 10.5.8 OS.

The issue i am having is that it will go into hibernate mode when i remove the battery when the power adapter is on the laptop and I cannot seem to wake it up at all. I have tried shutting down and attempting to run with just adapter with no luck. This issue has started in the past week ,before then it would run with just the adapter. I would like to be able to not have the battery in because I feel it will shorten the life of the battery and It wont be around as long if I have to continue to have to operate the laptop this way.

hope you guys can help
