It looks like the dream of laptop that can hold a full day of battery charge has finally arrived. According to an HP press release, the company has managed to get one of its laptops running for a full 24 hours on a single charge.
The notebook in question is the HP EliteBook 6930p, assuming you've bought some upgrades.
HP cites three primary factors for the stellar battery performance. The first is the $189 optional 12-cell ultra-capacity battery, which HP boasts can boost a notebook's battery time by up to 10 hours.
The second factor is an energy efficient, solid-state hard drive--HP used an 80 GB SSD for this 24-hour test.
The final factor HP cites is its Illumi-Lite LED display, which the company says uses less energy than a traditional LED display. HP notes in the fine print of the announcement that the Illumi-Lite LED displays won't be available until next month.
There was one other interesting factor that HP mentions in the press release: The operating system. The 24-hour test was done on a laptop running Windows XP. HP recommends using Windows XP if you want similar battery life results. Sorry Vista, that's yet another knock against you.
