So easy! First time ever opening a computer
I use my Macbook Pro, early 2011 13", for research that requires me to have dropbox, excel, word and some other programs open all at once. It used to be fine but slow, but in the past few months it was unbearable. I'd have to open programs and then leave the room for 20 minutes, come back and they'd be done launching. Such a pain.
I have literally never once opened a piece of computing machinery in my life. I was really worried I'd do something horrible, but seriously this was so easy. And now I have this cool toolkit in case I ever need to take apart anything with tiny screws again! It was really interesting to look inside my computer and finally get where all the parts connected. I had backed up with time machine on an external drive the night before, so that, and the few hours it took to restore my files on the new drive, took the longest. I'm really happy with how responsive it is and how quickly it boots up and launches programs now.
On the reboot, I didn't realize I needed to format the new hard drive before I restored from my external hard drive. So that was a scary few minutes while I panicked and tried to look up the answer on my phone. I figured it out! Also if I had really been thinking, I would've upped the RAM too while I was in there. Last thing: I took the pills out of my daily pillbox and used that to put the screws in while I worked-- a tip from the comment section of the repair page. That worked like a charm.
