Ok, so I got the battery changed no problem, installed the new hard drive no problem, but before closing it completely I decided to test it… there is power cuz it turned on but it has been on the apple screen for about 5 minutes now. I can hear the hard drive working..just wondering if it's taking so long because it hasn't been turned on in ages or if its because of the new hard drive. Can anyone help? Is this ha drive just no good?
