Hello to all. 

I’m explaining the title of my post. My wife had a Dell XPS 15 L502x which had issues with sound and touchpad and decided to give her my 1st Alienware 15 R3 i7-7700HQ. So I tried the following and worked fine. I made a clone of the SSD disk had the XPS on a M.2 PCIe using an external USB case. Placed the M.2 hard drive in Alienware, turned it on and just waited to install the appropriate drivers by its own. After the booting of the OS, did a manual Windows update and everything is now working flawlessly.

I repeat..

Aliens are magic machines..!!!

Love them..!
