There are some videos on line that show you how to do things like that, even with your own machine make and number. I found one for an older laptop (exact laptop) which even showed which screws to take out and in which order when replacing a hard drive! It's worth checking them out on a Search engine using your specifications. It might be that you are limited because of them. My latest is upgradeable but I probably would take it to a recognised specialist as it is still in warranty.
