no battery found after installing harddrive
After I have installed a better hard drive I have problems with the battery of the MacBook Pro. It seems it is recharging, but the MacBook Pro doesn't seem to notice it is installed. After resetting something to detect the battery by holding the power on button for 30 seconds and after that plugin the power cord the laptop is fine. But after closing the laptop the problems reappear.
Is this a good question?
