Tested and working. Unit has had its drive wiped and Windows 10 installed and ready to set up for first time use (DOES NOT INCLUDE ACCOUNT/SUBSCRIPTION). Units have enough battery life to use unplugged for a bit, but we cannot fully assess the remaining life/condition of the batteries. Assume that the battery life is well below its original battery life and we will not accept returns due to battery life issues. This listing does NOT include power supply or any other parts/accessories. Unit has moderate to heavy external wear including scratches, scuffs, marks, very tiny pockmarks, etc. Unit pictured is the worst condition of all units in this lot.
