Ok, I know it’s not much about my one year old Macbook, but I’m trying to renew my Macbook now 
Well, obviously I can’t afford a brand new model, but a little update and upgrade is possible though. Recently I just ordered a brand new Macbook upper case, mine one haven’t get any yellowish, but it’s a bit old and somehow, the lids are cracking some part of the upper case (Near touchpad).
At the same time, I’m planning to get some new rechargeable batteries as well. This original battery now only stay for 2 hours max! Nothing more nothing less, when I first got this Macbook, the power were more than 5000mAh, but not it’s only 3000+mAh, with only 87 cycles, I’m deeply suspecting this battery is coming to be faulty!
