HP EliteBook 8440w Core i7 Notebook Review
Power Consumption and Battery Life
We used
BatterEaterPro's "Real World" option to test the HP EliteBook 8440w's battery life. We didn't expect long of a life from a mobile workstation (particularly with a Core i7 and discrete Quadro GPU under the hood), but the 100WHr 9-cell battery gave us hope that it would at least last through a business meeting or video encode before demanding that we attach it to a wall socket.
Turns out, we were only able to squeeze out 2 hours and 10 minutes from the battery, and remember, this is the 9 cell battery. This was with the display on the entire time at 50% brightness, Wi-Fi on and a 3D graphic model spinning the entire time, exercising the GPU somewhat. That's not terrible for a Core i7-powered workstation, but it's not great, either. It's a little less than we expected, but it's clear that this machine isn't meant to be used for too long away from the power socket.

If you're interested in a
machine like this, with a need to compute on the go, we'd recommend
buying a spare battery. That said, for the average business meeting,
where GPU-intensive tasks are generally non-existent, battery life
should be considerably better than we've measured here.
