Replacing mackbook air 13'' battery and trackpad got a little loose.

My Problem

My original battery had problems with about 500 cycles and it was lasting only 20 minutes (sometimes less).

My Fix

Good. It's a very easy part to replace. The only problem I had was that, after changing the battery, my trackpad is a liiittle bit loose. When I click it, it makes a sound like it's a little loose..

My Advice

Be very careful when replacing the battery and, before putting the new one, check if the trackpad is fit correctly. At last, attach the new battery firmly.
