I have 2 Dell E6410s; one has a Core i5 processor 2.53GHz and the newest one has a Core i5 processor with vPro 2.63 GHz. This laptop came from a computer refurbisher and most come from businesses and sold to the general public. What is vPro? Is this some kind of odd-ball laptop? I know I take my chances buying used stuff for under $75.00. It runs Linux with no problem but could use 8RAM.
