This is not something you will be able to find out in a forum post since the components of a laptop are pretty complex unless you are just putting together parts already made. In that case, you just need a few screwdrivers, screws, thermal paste, maybe some adhesive and electrical and plastic high heat tape. Tablet and phone assembly is harder than laptops since the connections are often done by glue and adhesive strips and the parts are smaller and a lot more tightly packed. Not any different than putting together any computer just with much smaller and custom shaped parts.
Grab a laptop and a tablet, take them apart, then you will know what you need to put them back together again.
