I have an old Macbook Pro, It's got a dead battery as in it won't hold a charge and I think something is wrong with the logic board. I ran a diagnostic test on it and all it told me was I have a dead battery code: 4xxx/1/40000000 "Battery" I have just gone and eleted the hard drive and am attempting to reinstall the OSX from a USB stick however it's been stuck on the 'installing on untitled' 'About 14 minutes remaining' for over 2 hours now. Am I safe to assume there's something wrong with the logic board?
