I'm guessing that you have a mid-2012, 13-inch, MBPro?
That would have the built-in DVD drive (and the last model that can have an internal hard drive)
So, assuming that's what you have, the battery may be swelling (causing pressure from underneath the trackpad, and giving you erratic clicking, etc.
It's easy to take the bottom cover off, then remove the battery to check for swelling (it will be obvious to the eye!)
And, you can test the trackpad while the battery is removed, just to see that your trackpad works better without the battery... If that's the problem, all you need is a new battery.
You can assume it is old (that same model has been sold since June 2012), but that doesn't necessarily mean that the store won't swap out batteries.
You may be fortunate, because that model is still sold as new by Apple, and folks like it because it still has an optical drive, and the storage/memory is still easy to upgrade.
They may only give you the option to purchase a battery, as swelling is really one of the possible results of normal aging of rechargeable Li-On batteries. Take it in, and ask. Sometimes you get a happy surprise.
But, you should try to verify the swelling first, if you can.
Sounds like a good plan.we don't have an Apple Store in this country so if I want an exception made I'd have to call in to have on recorded before I bring it down to a authorised repair centre.
Sounds like a good plan.
So - You don't live in Ottawa, now?
There's two Apple stores in Ottawa, Ont.
About 30 in all of Canada (?)
