[QUOTE="chscag, post: 1435606, member: 46727"] You can check what's going on with the CPU by opening your Activity Monitor.app from Utilities and looking for whatever is spiking the CPU to 85%. I honestly don't know if a defective battery could be causing it to go that high. However, I do know that when a battery is either defective or removed from the machine, it will cause a slow down. This is a built in "safety net" by Apple. [/QUOTE]
