The Dell Latitude E6400 is a 14″ laptop targeted towards businesses that need good performance, solid design, and a commonality of parts for an entire workforce. This notebook competes against such notebooks as the HP EliteBook 6930p and Fujitsu LifeBook S7220. The E6400 offers a wide range of hardware configurations, as well as Solid State Drives (SSDs) for the businesses that require extreme ruggedness and extreme performance. Should your company rush out and purchase the latest generation of Dell business notebooks? We took a closer look to find out.

  • 9-cell (85Wh) Lithium Ion battery
  • Price as tested: $2,148 (starting price: $1,139 … $879 after instant savings)

Build and Design

Unlike the previous generation of Dell Latitude noteboks that featured rounded edges and curves, the Dell Latitude E-series features “down to business” industrial design. The chassis is entirely made of magnesium alloy with plenty of 90-degree edges and sharp angles. While the look is reasonably modern, it’s also a little “old school” and could be mistaken for a 5-year old laptop from a distance. Still, the build and design speak volumes in terms of the overall durability of this notebook.

During testing no plastic creaks or squeaks could be heard thanks to the magnesium alloy structure. The entire bottom shell is a metal alloy which gives the laptop a strong footprint on your desk, and gives enough strength to resist bending if you hold the laptop by the edge of the palm rest walking around the room. The only downside to the chassis is that the alloy is thinner than expected in a few locations (more on that later). Another minor issue we noticed is that the bottom access panel on the E6400 really needs one extra screw on the bottom right corner next to the hard drive bay. The magnesium allow base plate smacks up against that corner of the notebook and makes an annoying metal tapping noise if you’re typing on an uneven surface.

The heavy use of magnesium alloy carries over to the lid of the notebook, which has an attractive “brushed metal” design that isn’t actually brushed metal but rather a painted surface. This immitation brushed metal surface is available in black, blue, or red to give businesses (and their employees) a way to customize the look of their business notebook. The finish itself seems quite durable and should survive years of use and abuse.

In addition to the overall design of the notebook itself, it’s worth mentioning the new docking station for the E-series Latitude notebooks. Most businesses will likely use the E6400 with a docking station and an external monitor so that employees can have a mobile laptop when traveling and have a “desktop” computer at the office. Dell made a few changes to the Latitude docking station this year. In addition to relocating some ports they also added an extra USB port on the side and provide new DisplayPort connections for the latest external displays.


The matte WXGA+ (1440×900) screen on the Dell Latitude E6400 is absolutely beautiful. No dead pixels were found during testing, and backlight bleed while noticed on some dark screens was minimal. Colors were vibrant despite the matte screen and the additional benefit of matte screens is the lack of reflection in an office environment. Wide viewing angles made the screen look sharp even at oddly contorted angles. Backlight adjustment was very broad, allowing me to adjust low enough for darker room settings, and bright enough to still be readable in sunlight or a bright office.


One minor negative regarding the screen is that the notebook lid offers less than ideal protection for the screen. Although the allow lid is quite durable and should protect the lid from most impacts, the thin allow does flex and created “ripples” on the screen whenever pressure was allied to the back of the screen  The release latch was smooth and unlike most latches on budget notebooks required little effort to release.

Keyboard and Touchpad

The keyboard and palm rest structure is solid, but the thin alloy used in the palmrests does flex a little when pressure is applied. Pressing down very firmly, the keyboard suffers from virtually zero flex and is a nice improvement over the older Dell Latitude D630.

The keyboard is very comfortable to type on, and gave just the right amount of response for each key press. Key travel is similar to most business notebooks with just a bit less clicking sound than what we hear on ThinkPads in our office. The keyboard layout was not cramped at all, and the keyboard backlighting allowed for typing in a dark room.

The Alps touchpad has a nice smooth texture and is reasonably responsive, but could be improved. Lag time and accuracy were worse than what we’ve seen on many competing business notebooks. The size of the touchpad surface was large enough for comfortable control and the two touchpad buttons spanned the full length of the touchpad, and each had a soft click when pressed. The touchpoint/trackpoint located in the center of the keyboard is a nice improvement over the touchpoint on the older D630, but again we found the touchpoints on business notebooks from Lenovo and HP to be more responsive and accurate. On the bright side, the touchpoint includes three mouse buttons for better control with tabbed web browsing.

Next to the touchpad on the right palmrest you’ll also notice a SmartCard contact reader … allowing employees to use their SmartCard security badges with their notebook without having to physically insert the SmartCard inside the notebook.

Performance and Benchmarks

The Dell Latitude E6400 as configured has more than enough speed and storage space to handle most users needs. The high-end Intel Core 2 Duo P9500 and nVidia Quadro NVS 160M combined with a reasonably fast hard drive make this laptop an excellent performer, for both lightweight multimedia uses and number crunching. Below are benchmarks to give you an idea of how this laptop might compare up against other notebooks on the market.

WPrime 32M comparison results

wPrime is a program that forces the processor to do recursive mathematical calculations, the advantage of this program is that it is multi-threaded and can use both processor cores at once, thereby giving more accurate benchmarking measurements than Super Pi.

HDTune storage drive performance test:

For those who are interested in replacing the standard hard disk drive in the E6400 with a high performance solid state drive (SSD), the E6400 is available with the following SSD options and prices:

  • 64GB Dell Mobility Solid State Drive (add $499)
  • 64GB Ultra Performance Solid State Drive (add $649)
  • 128GB Dell Mobility Solid State Drive (add $649)


The speakers on the E6400 were better than average for most laptops, comparable to speakers found on most small midrange televisions. While lower bass was lacking, volume levels were quite loud, and distortion at peak levels was not present. The speakers also have a great location that directs sound up and toward the user.

Speaking of great locations, it’s also worth mentioning that the fingerprint reader is now located beneath the right speaker. This is a much better location than the palmrest or in between the touchpad buttons (where most manufacturers put the fingerprint reader) because it means you’re less likely to accidentally trigger the fingerprint reader when you pick up the notebook or use the touchpad buttons.

Input and Output ports

Port selection was not a problem, although I would have enjoyed seeing a HDMI port, but the inclusion of a DisplayPort is a reasonable compromise and probably more useful in a corporate environment. Going around the notebook, we find the following ports

Left: Kensington lock slot, VGA out, powered USB port, combo USB/eSATA port, heat exhaust, SmartCard reader, and hard drive bay.

Front: Screen latch release and SD card reader.

Right: PC card slot (ExpressCard slot optional), Firewire, optical drive, Headphone/Mic, wireless switches, and two USB ports.

Rear: Modem, LAN, battery, DisplayPort, Power connector.


Heat and Noise

The E6400 controls heat extremely well … even when the dual-core processor and GPU are crunching numbers and the hard drive is actively reading and writing data. Even after running PCMark05, 3DMark06 and wPrime multiple times during a one-hour period the exterior of the E6400 barely reached the triple-digit range in degrees Fahrenheit. More importantly, the hottest parts of the notebook are confined the the areas where you are less likely to touch the notebook. For example, if you’re using the E6400 on you lap in an airport the hottest part of the notebook is located between your legs rather than directly where your legs come into contact with the notebook.

Simply put, the E6400 with hard drive stays remarkably cool even when the system is being heavily stressed. If you configure the notebook with a SSD instead of a hard drive you should have a notebook that runs even cooler. The images below show the external temperature readings in degrees Fahrenheit:

The fan noise was rarely loud enough to be heard in a quiet room unless the notebook was under extreme stress such as benchmarking or serious gaming.


Under normal web browsing use the 9-cell battery performed quite well, pushing out 4 hours and 22 minutes of life before going into hibernation mode at two percent. Screen brightness was at maximum and other items were set to “High Performance” in Dell’s ControlPoint Power Manager. I also never let the notebook so to sleep during the battery test, so users should be able to get more than 4 hours and 22 minutes of battery life by selecting the “Dell Recommended” mode or “Power Saver” mode and letting the notebook go into sleep mode when not in use.

Dell’s Latitude team takes a great deal of pride in the development of the new ControlPoint software. This one-stop control center for power management, display settings, network connections, and security settings. ControlPoint is indeed a great interface for novice computer users or anyone who wants to control these features in one location. However, if you’re used to using the Windows power management interface, you’re in for a rude awakening when you change settings for screen brightness, or sleep mode only to have the Dell ControlPoint software override your changes and reset them to what it believes they should be. Of course, if you simply use the ControlPoint software everything is fine, or you can just turn off the ControlPoint application if you prefer to use the Windows interface.

In any case, more than four hours of battery life gives you more than enough time for taking notes, surfing the web, or responding to emails throughout the day away from an outlet. For those road warriors who require “all-day” computing, Dell also offers a 12-Cell High Capacity Battery Slice ($399) that connects to the bottom of the E6400. Dell claims the when the E6400 is running on both the 9-cell battery and the 12-cell battery slice it can provide a full 19 hours of battery life. Unfortunately, we didn’t have access to a battery slice for testing, but it’s safe to say that such a configuration would easily produce double-digit battery life with the screen brightness turned down.


The Dell Latitude E6400 is a great performer and a solid replacement for the Dell Latitude D630. It seems to be built well enough to be thrown around in day-to-day use, and it’s clear that Dell is trying to improve the Latitude line and offer compelling features … like 19-hour battery life.

We really couldn’t find any major reason to dislike the E6400, but there are a number of “minor annoyances” that could make some businesses look elsewhere. As we mentioned, although the E6400 proved to be quite durbale during our tests, the alloy chassis is thin in some locations which makes the notebook “feel” less durable than it actually is. We’re certain the thinner alloy sections where used in order to keep weight as low as possible, but flex is something you don’t want to see in a business notebook.

Overall, corporate clients who are looking for the next generation of business notebooks from Dell have plenty of reasons to buy the E6400. Dell made every effort to improve the Latitude family, and the E6400 is a great 14-inch business notebook. That said, there is some pretty strong competition such as the Lenovo ThinkPad T400 and HP EliteBook 6930p … and those notebooks might prove to be better alternatives for some.


  • Very tough structure and rugged overall chassis design
  • Excellent selection of ports and fantastic docking station
  • Excellent battery life … particularly with extra battery slice
  • Solid performance
  • Remains very cool where your body comes into contact with it


  • Industrial design (although cool) looks a little “unfinished”
  • Build quality is durable, but alloy chassis feels thin in some spots
  • ControlPoint software can be frustrating
  • Trackpoint/touchpoint is better than the one on the D630, but still not great
