My applecare is up in the next upcoming months, and there are bits and pieces of minor things that are going wrong with my mbp. do you guys think that it would be wrong to send it in have them replaced before my expiration date is up?
How could it be wrong? If it's something covered by warranty, they have entered into an obligation to fix it by selling you AppleCare. If it's something not covered by warranty, they won't fix it just because you ask them to.
Remember that general wear and tear isn't covered by a warranty agreement.
Optical drive failure/iSight failure etc etc is.
However if it's issues of crashing or freezing, erase and install the OS. If you've never done that before and your machine is approaching 3 years of age, it makes sense that you're experiencing fluctuations.
I wouldn't' recommend restoring from a TimeMachine backup or an Archive and install. You may just be transplanting the problem.
It's a chance for a new beginning!
Perhaps an excuse to upgrade to SL???
Would recommend booking a Genius appointment at your local Apple store and getting them checked out before your AppleCare warranty runs out. Them two components could be costly to replace if they were to fail outside of warranty.
