HP may be gearing up to refresh its Mini 311 netbook with the launch of Windows 7. According to MyHPMini.com, tucked away in the Mini 311's Maintenance and Service Guide is information showing the system's future specification offering. For what it is, the Mini 311 is already pretty well equipped, featuring an 11.6" 1366x768 display, Nvidia Ion LE graphics, Intel Atom N270, 1GB of RAM, and a 160GB HDD.

If the manual is any indication, HP's flagship netbook will soon be available with the full Nvidia Ion platform (only with Windows 7), 2GB or 3GB of RAM, an 80GB SSD alongside a 250GB or 320GB 5400RPM HDD (only with Windows 7), and 32-bit editions of Windows 7 Starter, Basic, Premium, as well as Professional. Note that the current Mini 311 does support up to 3GB of RAM -- HP just doesn't offer more than 1GB as an option.
It's unclear whether or not the company will actually ship the Mini 311 with your choice of the four mentioned Windows 7 versions. The netbook is currently priced at $400 and Windows 7 models are expected cost an extra $75, so with the bumped hardware specs you'll probably be plunking a hefty coin for HP's upcoming Mini 311.
