Refurbished a used 2011 MacBook Pro
Mijn probleem
The original trackpad was not tracking correctly and there was a battery warning.
Mijn oplossing
Good. Some trial and error while adjusting the trackpad, though.
Mijn advies
Removal of the bottom case, battery, and trackpad was very simple. Proper alignment of the trackpad and the top case was more difficult. If the side of the trackpad is too close to one side of the cut out in the top case, it will rub against the side when pressed down and may get stuck. Also, if the set screw for the switch is adjusted to far down, the track pad will not move at all. It is best to power up the laptop by connecting the power supply with the battery out to allow adjustment and testing of the trackpad allignment and button clicker adjustment screw. I stripped the heads of a couple factory screws on the trackpad trying to remove them. I replaced them using the screws that came with the new trackpad, but I was surprised they were so tight. I took care not to over tighten the new ones. I also replaced the battery during this repair. The screw tabs on the original battery were actually broken. It looked as if those screws had been over tightened as well. I also took care not to over tighten those screws. Also, I recomend reseting the system management controller on the macbook after replacing the battery.
