Hewlett Packard has refreshed its Pavilion, Envy and Mini notebook lines and they are expected to ship in late May and June.

Aside from redesigns, HP also delivered some rather changes under the bonnet. The refreshed lineup will be HP's largest single launch of notebooks powered by AMD processors. We still don't have the exact specs for AMD-based Pavilions, but they will obviously feature new Phenom II mobile processors in dual, and probably tri and quad-core flavors.

HP claims that the addition of AMD chips will provide consumers with more options and, more importantly, lower prices. HP also dropped the price of its stylish Envy brand notebooks. The entry-level Envy has had its price cut from $1,299 to $999.
