I'm sorry I haven't read all the posts,but the words "Dell XPS" caught my eye,and hmm,I unknowingly bought one of the i7 2630qm Sandy Bridge XPS 15" Laptops at my join date,and lets just say,I ended up building a custom made desktop[signature],VERY soon after,due to having no end of hassle.
Dell,and like minded[?] brands[especially the desktops-Scott,or Jim Roseberry could explain?] were NEVER mean't to be Daws,the craziest thing is with X2 NOW -the laptop I'S ALL I USE NOW[95%]
But it took a lot of bluescreens/shutdowns,complete unexplained weirdness,and no end of it,to get it,to the sometimes semi reliable machine I use daily now,and X2 is at least as stable[and uses less cpu][NOW]as X1D Expanded was,with a few niggles[copy-drag- paste,works every second attempt].
I researched for ages before getting the desktop,and as this laptop slowly[?] wears out[the touch pad is getting un-responsive]I'll be super glad I bought the lean mean overclocked desktop,to move to,even though it's Sandy Bridge[Ivy is NO better-Scott from ADK assures!]and it is now 2 years from when the cpu was released,and it's good for at least another.
Good Luck,hopefully the exactness of your issues can be worked out,it can be done,but...

Ps Ahh,I kinda get it after reading some more[???],oh well,and just so anyone who could care to know,I hang on Gearslutz all the time,I especially like the name,and it's nowhere near the deal people seem to make it out to be YMMV?
New Song on soundcloud-ok.
I been up a good 30 or so,good night chaps. FacePalm!!! I've now had some much needed sleep,yes my Dell XPS Laptop is a totally cool daw with X2a,and to say that Dell desktops are truoblesome,was just a tad stupid......any computer brand can be made into a great daw,and with FireWire it's Texas Instruments for sure[just one of the SUPER IMPORTANT pieces of info,gleaned from "Jim Roseberry",and"Scott@ADK's"postings!]
Its just if I'd had to do,what I did back in April 2011 again[when when I first got into "my digital dog n pony" I may have shopped differently,and like I said 95% of X2 use is this L502x Laptop,and MOST of the trouble I had was "user error" or "user do not have clue",for instance I love my new N.I.KA6 USB Interface [best performing sub $300 interface in Oz arguably],but I am getting blue screens[3 in 3 months]that I was not getting before when using ASIO4all with line in,is it the "interface"?? I don't know,and a reboot always comes back fine,and all of the shutdowns were while on the net,with MSE,and no virus's etc detected.
Anyway,hope all is well again in Denmark!
