Upgrade paths

RAM

None, 4 GB soldered to the mainboard · Not expandable or replaceable, one of the first ultrabooks to fix RAM in place for thinness.

LOCKED

storage

Standard mSATA SSD swap for a larger-capacity mSATA drive · The SSD is a removable mSATA module rather than soldered, so it can be swapped once the bottom panel is off.
