This device was used exclusively in an office setting and is very clean and the backlit keyboard pops!  Device was disassembled, cleaned, and reassembled with a NEW high capacity SSD, 16GB RAM, and a NEW power adapter. The fan was cleaned from dust and debris and new thermal paste has been applied to the CPU which can get old and be less heat-conductive over time.  Please see my feedback and buy with confidence.
