I have purchased two previous refurbished Elitebooks, both the previous model to this one..model 8460P.  I have been very happy with those so bought this one year newer model. It arrived quickly and the example I received looked like new, no blemishes or marks on the exterior. It's very simple to gain access to the insides, the metal bottom is removable in a few seconds with no tools.  That allowed me to check the condition of the inside as well. The CPU cooler fan and the area around it were clean...no dirt or dust buildup at all. The eight GB of ram was configured as two 4 GB sticks. This model can handle as much as 16 GB of ram.  It came configured with an up to date version of Windows 10. Updates that had been made available by Microsoft a couple weeks ago were already installed.The computer runs very nicely and with the speedy Samsung SSD drive, it's fast. Boot up time is less than 10 seconds. HP Elitebooks are built to a higher standard than their regular consumer lines.
