Additional SSD installed: Samsung 850 EVO - 250GB - M.2 SATA III Internal SSD (MZ-N5E250BW).
The machine is fast and powerful; I bought it a few years ago for $912. The additional SSD cost was $199. I'm selling the laptop because I've transitioned to Mac.
The battery is not charging/not holding any charge, but the laptop works great when plugged in. The battery will have to be repaired or replaced if you plan on using it without the power cord.
The top panel has a small cosmetic dent (see the picture).
