Don't even think about trying to repair or upgrade the Surface Pro 2, because it's just as tough to crack as the original, according to iFixit.
The group, which is known for its device teardowns, gave the Surface Pro 2 a repairability score of one out of 10, same as the first-generation Surface Pro. As with the original, the insides are loaded with adhesive, and iFixit counted more than 90 screws holding everything together. (Apple's fourth-generation iPad, by comparison, earned two repairability points out of 10.)
Breaking into the Surface Pro 2 requires a large heat gun to poke at the adhesive, while preferably inserting special picks to pry everything apart. Microsoft used 52 screws of three different sizes to hold the motherboard down, same as the original Surface. (The motherboard is shown above in an iFixit photo.)

The Surface Pro 2's innards aren't a major reworking from the first-generation, with the notable exception of Intel's fourth-generation "Haswell" processor. The cooling fans are exactly the same—Microsoft uses some software tweaks to fire them up less often—and the motherboard still looks like a stern face, except it now has more of a blueish hue.
