Alienware M11x R2 Review
To test the M11x battery life we used the laptop in three different scenarios. In each the Windows 7 power profile was set to balanced and all on-board devices were enabled as was all system lighting.
In the first test we performed standard tasks such as surfing the net, speaking on Messenger, watching YouTube content, emailing and typing in Word. With all these activities taking place and the Intel GPU enabled we achieved a battery life of 5 hours and 12 minutes, a little less than our original M11x sample but still very good.
Next we began watching a 1080p file which was being scaled down to the LCD resolution. In this scenario the machine gave us 3 hours and 45 minutes of use, more than enough to watch any recent movie… possibly even two.
Finally we began gaming in full screen mode, the most demanding task likely to be performed on the M11x. The system gave us 3 hours and 3 minutes of life in this task, far more than we would expect from a high performance system.
Before taking the temperature of the system the M11x was left idle at the desktop for 30 minutes. For the load tests we ran Prime95 on the CPU and Furmark on the GPU.
Idle temperatures for the M11x are reasonable for the components installed and it was interesting to see that very little of this heat makes it onto the bottom of the unit. This makes it very comfortable to use on our lap.
Load temperatures when viewed in a graph do seem a little high but once again these don’t tell us that the M11x is designed so that it can be used on our lap even when under load. The bottom of the chassis never becomes too warm as the vent of the base is used to draw in cool air before immediately exhausting hot air out the back of the system.
