Hewlett-Packard didn't let Dell claim it had the longest battery life too long. HP said Monday that its HP EliteBook 6930p ran 24 hours with an ultra-capacity battery. For those keeping score at home Dell said its new Latitude lineup breaks the 19 hour battery barrier.
HP's statement rattles on about a whole bunch of features and what it all means, but let's go right to the footnotes. How did HP get 24-hours out of its battery?
Requires separately purchased Ultra Capacity Battery and customer download of the latest Intel graphics driver and HP BIOS. Notebook must be configured with optional Intel 80 GB SSD drive and HP Illumi-Lite LED Display (planned to be available October 2008) and requires Microsoft Windows XP operating system. Battery life will vary depending on the product model, configuration, loaded applications, features, and power management settings. The maximum capacity of the battery will decrease with time and usage.
And oh yeah HP doesn't want the government to add this battery life claim into contracts:
Testing was not intended to demonstrate fitness for U.S. Department of Defense contracts requirements or for military use. Test results are not a guarantee of future performance under these test conditions.
HP added that the EliteBook will come with high performance solid state drives from Intel (HP is a launch customer).
