A:
I have seen both answers to this question, that you can and can't add RAM. Possibly it depends on different configurations of the same model. since I know that it is available both with and without an optical drive (mine, purchased years ago from another dealer, came without one). As an example, I looked on the Kingston website and it says 4GB is the maximum, with one slot, while Crucial tells you that there are two slots and 8GB is the maximum. I can tell you that mine was upgradeable, to at least 8GB, possibly more, but it is nerve wracking to do it if you have never opened up a consumer level laptop before. First, you have to remove 9 screws on the bottom that are three different lengths (which means you have to put them back in the same places you removed them from). Then, you separate the two halves of the base (carefully, don't break anything). Next you have to detach three delicate cables from the motherboard. Then you have to detach three other cables from the motherboard, in addition to the connectors to the WLAN chip. Then remove the HDD. Then another bunch of screws holding the motherboard. Finally, you can remove and flip the MOBO and, if you're lucky, there will be the one stick of RAM to be exchanged. If you've successfully done all this without damaging anything or killing yourself, you now have to do it all in reverse. Warning: the worst parts of the reassembly are the cables and connectors (I had an especially bad experience with the WLAN connectors). Advice: before you snap the two halves of the base together, try to power it on; if you did EVERY. SINGLE. THING. right and it boots up without issue, great, congratulations. If not, you have to do it all over again and prey you haven't just wasted $200+. BTW, I was only able to assay this task by way of a set of very helpful videos on YouTube, which I highly recommend before you do the same thing.
