Solved Macbook Will Only Power On If The Battery Is Unplugged Macbook Pro 15 Non Unibody
Chosen Solution Hi so I have a problem. I found my old Macbook Pro 15 in non-unibody from 2008 I believe. I am really inclined to get it to turn on. So far the only method that has worked to get it to turn on is if I remove the battery, hold down power button for 10 seconds, plug the charger back in and continue to hold power button for 10 more seconds then release it....
