24 Hour Barrier Broken
HP announced yesterday in a press release that they have broken the 24 hour barrier for battery life. Their new notebook, the EliteBook 6930p will be made available with an ultra capacity battery, which offers 24 hours of continual usage. They have employed a few techniques in the overall notebook design to help achieve this, such as Intel solid-state hard drives (SSD) and mercury-free LED displays. The highly efficient HP Illumi-Lite LED display boosts battery run time by up to 4 hours compared to traditional LCD displays, while the Intel SSD provides up to a 7 percent increase in battery life compared to traditional hard drives. You also need to be running Windows XP, using the special HP BIOS and have the latest Intel drivers installed to be able to get 24 hours usage.
The notebooks are aimed at the business user, and it's claimed the battery would last long enough to complete the world's longest airline flight, the Newark Liberty International Airport to Singapore Changi Airport flight taking 18 hours and 40 minutes, without needing recharging. HP stated that the battery runtime was tested using 'industry specific benchmarks' but never elaborated on that. They have stated that exact runtime of the notebooks would vary according to the product model, configuration, loaded applications, features, and power management settings.
