Dell Latitude E6400 review: Dell Latitude E6400

While the Latitude E6400 has the same Core 2 Duo P8400 processor as some other Centrino 2 laptops we've tested, such as the Lenovo SL400, its faster 7,200rpm hard drive helped it get a slight edge in our performance tests. But all the extra security features running on a business laptop can also eat up CPU cycles, so in terms of pure performance, you can take an older CPU and add a ton of RAM and get faster scores--as in the case of the Dell Studio 1535-125B, which has a 2.1GHz Intel Core 2 Duo T8100 and 4GB of RAM, twice the memory of the E6400. In hands-on testing, we had no problem multitasking on the Latitude, working on office documents, surfing the Web, and playing back media files simultaneously.

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.
