The Elitebook 6930p is what HP claims is the first laptop that can last a full 24 hours on a single charge, nearly six times more than your average laptop, while offering similar or better performance than the competition.
Obviously, this kind of battery life comes at a premium; in this case, you will have to opt for a solid state drive rather than the power hungry spinning type, accompanied by the HP Illumi-lite LED instead of the normal LCD version and get the 12-cell Ultra Capacity Battery.
The OS of choice will be Windows XP professional, not Vista which is apparently more frugal; The Elitebook as its name implies, aims entreprises with deep pockets (ed : and employees who are prepared to work for 24 hours a day) and it is only a matter of time before the technology percolates to other models.
On top of that, the laptop meets stringent MIL-STD 810F military standard tests which means that the drive can withstand some rough handling while operating at extreme temperatures, thanks to an internal inner magnesium shell and the lack of any moving parts.
The 24-hour model will be on sale for USD 1816, but no UK pricing or availability has been announced yet.
