Macbook

i've been using this old macbook for, let's see, how many years now. The track pad is now so worn down, it's like in a mediaeval church. If the power supply gets knocked out, the whole computer just goes bew and just dies completely. So there's also plenty of other issues with it. It's time to get a new mackin. Paul er brought me one to day, and i've got it in a box. Going to open it later. Do you have any tips? Like, should i, how should i? What shall i do? Iunbox it? Shall i charge it immediately? Or you don't have to
