You are looking at a Lenovo P53 Mobile Workstation that I ordered new from Lenovo and used as a software development machine until there was a failure in the disk subsystem. It's unclear if a member drive of the RAID array failed or the disk controller itself failed but it appears to be the former. Either way, the drives are NOT INCLUDED in this sale and no guarantee as to the functionality of the drive controller is made either. The laptop is very fast and well optioned out. It shows the typical Lenovo signs of wear: key surfaces getting shiny, the touchpad getting shiny and some of the color coating wearing off the front and side of the case. There are a couple of scuffs on the top of the case as well. The touchscreen shows some scuffs on the lower left side but functions normally. The battery had typical life for these systems when last used last summer - about a couple of hours with the display set to medium brightness and the system set for max performance but the battery has not been checked recently and no guarantee of its longevity is made.
