E403SA seems to be one of those laptops where you can't upgrade anything (CPU soldered to the MB, can't handle more than 4 GB of RAM etc.), but since I have a spare 500 GB 2,5" SSD, I'd like to install it to upgrade the 128 GB eMMC. Can I install it, or is the current mass storage soldered to something or a differnt type than the common 2,5" SATA disk?
