To test the battery today we put the machine through three sets of real world situations.
One as a media movie lover on the move, a person wanting to watch HD media on a train journey or bus with two thirds screen brightness (any less and quality suffers).
Secondly as a business man, using the machine for productivity with wireless enabled and balanced power settings with a mid way (around half) brightness setting.
Thirdly as a gamer on the move, with the nVidia graphics cards fully active and screen brightness up high.
The 12 cell battery is a powerful unit, but the demands placed upon it are intensive. We managed to get 2 hours and 40 minutes out of the system when using it for general work, which isn’t a bad result considering. When gaming, we recorded a little less than 1 hour and 20 minutes. It is worth bearing in mind that this is purely a desktop replacement system, not a businessman’s portable ‘workhorse’ for office work on the move.
