Upgrade paths

RAM

8 GB DDR3L-1600, soldered · Memory is soldered to the board on this first-generation ThinkPad Yoga, so whatever configuration it shipped with (4 GB or 8 GB) is permanent.

LOCKED

storage

M.2 SATA SSD, per commonly reported teardown capacity (2242/2260 form factor depending on revision) · Reaching the M.2 slot means removing the bottom cover and a fair number of screws; well documented in third-party teardown guides but more involved than a typical ThinkPad bottom-panel swap.

~$40-60

MODERATE

battery

47 Wh internal pack · Internal, non-swappable battery under the bottom cover, a consequence of the convertible hinge design rather than a hot-swap external pack.
