The Lenovo Y560p eschews high end design for reasonable pricing, and that means it doesn’t look like a tricked out gaming rig (Alienware) nor does it have the classy looks and metal casing of the HP Envy or Lenovo’s own IdeaPad U260. The design hasn’t changed significantly from the outgoing first gen Core i Y560 line. The lid is a mid-gloss faux brushed metal affair that’s made of plastic and it has some flex that’s most notable when pressing down on the closed lid. The keyboard deck is gloss plastic that loves fingerprints, while the bottom is the usual matte plastic with plenty of air vents. The fan fires out the left side toward the rear and the DVD burner (optional Blu-ray available) opens on the right side. The DVD drive’s door curves around the edge toward the bottom on this relatively slim 0.79"-1.3” computer, and as a result it’s easy to accidentally open the drive tray when moving and carrying the running machine.

WellHope it helps http://liwu.info/251299/optical-disc
