Hi, I have a MacBook A1181 with the removable battery type. The symtoms: I plug the AC adapter in and turn on the Notebook. All works fine. I take out the AC adapter and the screen dims as desired. About 10 mins later the Notebook shuts down. With the AC "unplugged" I try to switch it back on but it doesnt Diagnostics: I check the all the connectors to the battery for corrosion etc. All look perfectly fine. Used statpro to check battery etc: 100% indicated. I pressed the battery life indicator on the bottom of the battery "All green" Has anyone come across this issue before and do you think the Battery is the problem?
