I meant OPTICAL drive, not ocular drive. Oops.
I have a late 2009 model 15" unibody MacBook Pro that took a fall a couple of months ago. The computer itself is fine, boots fine, runs fine, rarely hits over 130 degrees (right now it's at 113), and for the most part seems to be in just as good of a condition as before I dropped it.
However, there are some problems with the keyboard, and by extension (I think), the ocular drive.
I have to wonder if something inside of the keyboard bent or got knocked out of place. Upon startup, the ocular drives makes an awful lot of noise (more than normal), and it sounds like there's something stressed or grinding in there that either makes a part skip or attempt to read the drive over again 3 times before giving up and allowing things to progress normally. It also does this sound when the computer comes out of sleep mode. (Incidentally, the computer seems unable to go into sleep mode and stay there anymore. It will try when I close the screen and continue through a cycle of going to sleep and waking itself up until I open the screen again.) The keyboard has problems reading keys correctly, and only a few keys have their original function. Most of the f-keys retain their function, however, the escape key functions like the f12 key and the f12 key, aside from its normal function, triggers the ` key. Touching ANY key on the built in keyboard interferes with the trackpad functionality. The trackpad will behave as though the command key is always pressed and will always right click. It is still possible to use a USB keyboard without any problems, and typing with any key on a USB keyboard fixes the interference with the trackpad. The keyboard's backlighting behaves normally and doesn't appear to be damaged.
Does this sound like something that can be repaired manually by opening up my Macbook on my own, or will I have to send it to Apple/a repair service? I've been avoiding sending it in because getting repairs directly from Apple is notoriously expensive. However, I also don't want to do anything that will damage my computer in a more serious and irreversible way. Any help or advice anyone could offer would be enormously appreciated.
PS- All mouse and keyboard settings have been restored to default just to see if it would make a difference. It doesn't. (which seems to be the obvious answer, since it only started giving me problems after being dropped...)
