Is Hewlett-Packard (NYSE: HPQ) readying a new notebook running Google’s (NASDAQ: GOOG) open source Chrome OS, perhaps joining Acer, Lenovo and Samsung in what appears suddenly to be a growing list of vendors interested in the cloud-centric Chromebooks? If you believe the accuracy of a PDF file found on the vendor's website replete with the new model's specs, as reported here, then the answer is yes.

According to the spec sheet, as it appeared on HP’s online store, the new unit is called the Pavilion Chromebook. Its most distinctive feature may be a 14-inch, 1366x768 display, making it the largest screen compared to the 11.6-inch entries sported by Acer, Lenovo and Samsung Chromebooks.

These days, it’s difficult to tell if HP purposely posted the specs to stir up interest in the Chromebook prior to its posted “ad embargo” Feb. 17 date, or if the information arrived on the vendor’s online store site by accident. We’ll never know, but in the meantime, the spec sheet detailed the Pavilion Chromebook running on a 1.1GHz Intel (NASDAQ: INTC) Celeron Processor 847 with 2GB of memory and 16GB of storage. According to the specs, the notebook will sport three USB 2.0 ports, an HDMI port, an HD webcam and a multiformat digital card reader. One possible drawback to the machine is its limited battery life, which, according to the spec sheet, is slightly more than four hours. No word, of course, on how much the HP Chromebook will cost.

It may be too early to say, but a small movement may be building with some leading vendors leaning toward Chromebooks as a Windows alternative. Based on Google chief Larry Page’s Chromebook comments last week during an earnings call, it’s apparent the vendor is making a strong commitment to the platform.

HP is one of Microsoft’s (NASDAQ: MSFT) most loyal customers and if it were to bring a Chrome-based notebook to market, while it’s imprudent to overstate the case, at the very least you’d have to figure the move would catch the software giant’s attention, just as Lenovo’s education-aimed Chromebook must have raised an eyebrow or two in Redmond.
