Dell Latitude E6400 14.1in Business Notebook - Performance and Verdict

Andy Vandervell

By Andy Vandervell



Our Score:


For testing our system came supplied with the entry-level processor, the 2.26GHz P8400, with support from 2GBs of RAM, a 160GB 5,400rpm hard drive and integrated graphics. As standard all systems come with a six-cell 55Whr battery and this was what was used for testing. Other options include a nine-cell 85WHr battery, which combined with an optional 12-cell "battery slice" that sits under the machine, is the source of the much publicised 19 hour battery life claim Dell used in its launch headline.

We, of course, couldn't be less interested in such headline grabbing claims but nonetheless the E6400 delivers very impressive results in MobileMark 2007 battery tests. In the multitasking Productivity suite it managed four hours and 45 minutes, around 15 minutes more than both the Samsung Q210 and Dell Vostro 1310. In the lower intensity Reader test this increased to over five hours, clocking up a super five hours and 35 minutes. DVD playback meanwhile, with screen brightness at maximum, was a still impressive two hours and 37 minutes.

Suffice to say, then, battery life is very good indeed and would no doubt be better when using Dell's extended battery mode, something we unfortunately didn't have the time to test. Application performance was also perfectly acceptable. Our system came loaded with 64-bit Vista Business, which accounts for some differences in PCMark Vantage over similarly specified systems, but nonetheless our in-house testing (run using a 32-bit install) show the E6400 performs perfectly well. Indeed, unless you have some special need, the "entry-level" processor should prove more than adequate for 90 per cent of a company's workforce.


A powerful, flexible, sturdy and well designed portable all-rounder, the Dell Latitude E6400's design and functionality caters very well to the needs of a wide range of users, be they relatively undemanding users who want something practical and long lasting, to power users that need to multitask extensively while on the move. Throw in a pleasing but serious aesthetic design and it becomes very easy to recommend.

Nice video review but can it really be as great as you say it is? Are there no negatives at all?. Ive been looking at this laptop for a while now and its a choice between this or the dell precision m2400, has anyone got any thoughts on which is best?

I had many laptop in my hands but hard to say anything really bad about E6400. I got it a few weeks ago with 9 cell battery, slice battery, Vista 64bit and basically everything you can get from Dell. I still like more D630 where a 9 cell battery is in the front and works well as a palm rest for me. Slice battery is a great idea but it adds weight of course and make the whole laptop really thick - you can forget about putting it in 14" sleeve. I had some problems with the finger print reader and preboot authentication and had to disable it because I have seen a few times a blue screen in Vista. I haven't tried it again after latest bios update tho. The last think but not so important are built-in speakers I think they could install something more power.

This laptop is almost perfect. but i really dissappointed with the review published here for its accuracy. The laptop does not support MS/ MS Pro media. I bought the laptop after reading the review here.

Would you please consider adding an additional performance test to your laptop testing? I think it would be useful to list the measured temperature on the underside of each laptop (at 50% load) to gauge whether or not the laptop would actually be cool enough to rest on the lap - let's call it the "crotch comfort factor". It seems that no laptop reviewers do this sort of test today, but surely a major point of a "laptop" should be that you can work with it for long periods of time resting on your lap without having to have a fan cooler in between!

I got this laptop 6 monts ago, and I still miss my old one. Beside the keyboard - superb in every aspects - there's not much shining here. The touchpad and stick are extermely difficult to use. The speed is on par with what one can expect, same for the display. It is quiet most of the time, running outlook & word on windows XP at least. It is more heavy than advertised (mine is 2,5kg). The design is really nothing special. The main issue comes from wifi reception. While my fujitsu, old dell and macbook show excellent signal strenght, the e6400 is getting a low to very low signal, and suffers from frequent disconnect.
