On the heels of unveiling seven freshly minted all-in-one machines yesterday, HP has refreshed yet another computer series, introducing a new Pavilion dm1. The company's latest ultraportable offering will be configurable with Sandy Bridge ULV silicon from Intel and E-Series Fusion products from AMD, including the upcoming 1.65GHz E-450. HP's press release mentions "discrete-class" graphics, though we assume alludes to the Radeon core inside each Fusion APU.

The 11.6-inch machine will still carry a 1366x768 panel, weighs 3.52lbs and measures roughly an inch thick. Aesthetically, the chassis has been slightly reworked and HP will coat the lid in a soft rubber material. The dm1's chiclet keyboard looks par for the course, but it has received an improved touchpad with two mouse buttons instead of its predecessor's single-touch solution. HP has also added its latest Beats Audio engine to drive your favorite speakers.

This update isn't entirely about shipping the dm1 with today's finest hardware, as you can supposedly expect a more streamlined Windows experience thanks to the company's "Premier Experience" software, which includes HP CoolSense, QuickWeb, ProtectSmart, SimplePass and Launch Box. Those technologies improve Windows' boot up, shutdown, sleep and resume times, but HP places the most focus on Launch Box, which augments Windows 7's taskbar.

The dm1 will launch in "charcoal" grey and "ash" black colors. The former style will arrive first with AMD chips, 4GB of Ram and a 320GB hard drive for $400 on September 21 alongside many of the aforementioned all-in-one PCs. A grey version outfitted with Intel's Sandy Bridge platform will ship over a month later on October 30 with a bundled optical drive for $600. Black models powered by either camp are expected to hit shelves sometime later in the fourth quarter.
