i got lucky and scored a M17x alienware laptop but i dont know what is the diffrence between them, i see some of you have a R3 or R4 how do i know wicht i have
alright i found out its an R3, and iv been looking for a keyboard replacement but only ones i can find dosent match the one i have, but the description shows it works on R2,3,4 is this accurite ?Hopefully you still have the service tag sticker on the bottom of the laptop. If you do, enter it on the Dell Support site and it will tell you everything you need to know about your machine. You can also post a picture of the machine and let us know what CPU/GPU it has and it's pretty easy to work it out.
