Afternoon all, i'm looking for some advice.

I've got a 2013 Alienware 14 R1 with 8gb of RAM with the following processor - Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz 2.40 GHz

I'd like to double the RAM.

A well as this i also have had a problem with it for a while now not charging. So it works plugged in and it won't switch on when it's not plugged in so i'd like to fix this problem too. And finally the the power socket feels loose so i'd like to fix this as well.

Is it worth it? and is it possible?

Thanks
