Dell Latitude E6400 review: Dell Latitude E6400

It's not intended for gaming (after all, you shouldn't be gaming on your work laptop, right?), but the 256MB Nvidia Quadro NVS 160M GPU (a $70 upgrade over the default integrated GMA 4500HD graphics) should help with graphics-intensive work, and also ekes out a barely playable 16.8 frames per second in Unreal Tournament 3 at 1,280x800-pixel resolution.

Dell has promised up to 19 hours of battery life if you combine a 9-cell battery with the optional 12-cell "battery slice"--essentially a giant battery that fits over the entire bottom of the system. We tested the 9-cell battery alone, and were very impressed with the 4 hours and 27 minutes we got from our video playback battery drain test. That's second only to the 12-inch Lenovo X200 in recent memory (that system topped 6 hours in the same test), and Dell's emphasis on keeping your laptop going for as long as possible is good news for on-the-go workers.

Business laptops generally offer more generous warranties than consumer models, with the default term starting at three years of next-business-day on-site service, A wide variety of extensions and add-ons are available, from extending the basic warranty to five years for an extra $249 to $79 to upgrade to Dell's ProSupport level of service, which includes "direct line access to North American-based technicians." Dell's support Web site also provides FAQs, troubleshooting tips, real-time chats with a support representative, and a user forum.
