The HP Pavilion dm1z was the 2nd model of its kind released by HP in 2011. It is designed to be ultra- portable and relatively less expensive than other HP models. Its common name is HP Pavilion dm1, but this model can be identified by its model number "dm1z-300".
It is distinguishable from other models because it is relatively smaller than the dm2 and dm3. With a sleek slim look. This laptop has a 1.6 GHz processor, 4 GB memory, a webcam, and Windows 7. A new feature on this model that is not present in other models is the hidden screws underneath the foot pads.
