Hi, its been two weeks and a half since I got my laptop. I just recently downloaded coconut application, one thing I got really worried about was that my original battery capacity was 5770mAh and and my current is 5613mAh. Also, its already down to 97%.... Is it normal for the battery capacity to go down this fast? Im just really worried because it is a pretty expensive machine...

Edit; oh jeez I just noticed that the backlit light for my letter "B" is dimmer than the rest at a certain angle... Is this also normal?

It is normal for a battery to lose som mAH but it will surely get it back once it gets calibrated. The way you calibrate a battery is by letting the charge run out completely by lowering the brightness and turning off all bluetooth, wifi, and peripherals so its in battery saver mode for the last 3 or 4 percent this way it drains the battery more efficiently. After the laptop turns off or hibernates, wait 10-20 minutes, then plug the charger in and dont disconnect until you get a full charge.

I don't know about the keyboard issue but I believe it is very common and is covered under apple warranty anyway.

Cheers.
