Laptop delivers all-day computing
Hewlett-Packard (HP), the world's largest computer company, has developed a new generation of laptops with a 24-hour battery life.

Surely you'll give up before this does
The firm says the 24-hour battery means travellers can take more than 10 trips on the Eurostar between London and Paris before recharging their laptop.
The company said the record battery life arises from a combination of HP engineering and energy-efficient notebook components such as Intel solid-state hard drives (SSD) and mercury-free LED displays.
It is worth noting that the 24-hour figure can be reached only by purchasing the ultra-capacity battery and upgrading the base model of the 6930p to include the Illumi-Lite display and 80 gigabyte version of the SSD.

"The HP milestone is an example of the impact of this new level of performance that specifically delivers on lower power consumption for longer battery life."

The new HP EliteBook will be available in October.
