hey guys...ok so i have a dell xps m140 which is not made anymore...its not a very old computer but its got 2 or 3 years in it already...but its still a very good laptop...however...after using my desktop for so long this laptop with an intel pentium m processor squeezing only 1.8gh...is kinda slow for my taste...but its still got 2 gb of ram so i was wondering if there is anyway i can replace the cpu with a duo core or something faster...is that even possible?
