Macbook questions?
Hi, so I recently got my macbook pro trackpad fixed, but I have been paranoid that I ruined my trackpad again. I was eating oily food, and my hands were oily, and I forgot to wash, and I touched my trackpad maybe even on the side. I mean, it makes the clicking side, and it's not particularly hard to click, but I am pretty paranoid. Can my trackpad stop working from my oily hands? Also, I am paranoid because the top sides of the trackpad is harder to press. Is that normal? The bottom sides work fine. Also, I was wondering on how to take care of my Macbook battery. If I were to set it down somewhere, would a bed sheet or pillow be ok? I usually put it on my lap when I am working or on a pillow when I am drinking liquid, which was a few months ago. There has been a time when I have spilled a liquid beverage on my keyboard, but all of my keys work perfectly. I do not have any problems with my keyboard, but I am paranoid that it's damaged even though it works. Also, I want to know if I can troubleshoot my trackpad to see if it is properly working and not messed up in any way. If so, how do you do that?
Btw, I have a keyboard cover
