DELL E5440 SPECS PDF

The Dell Latitude E is aimed at those people. The design of the E is decidedly inconspicuous, with matte black plastic the order of the day all round. The full width of the 15in chassis has been used to provide a separate keypad alongside the keyboard, as well as discrete volume control buttons at the top. The keys are full-sized and have a comfortably firm action, making touch typing for long durations very pleasant. However, we reckon this would be a false economy now that screens are pushing to 4K, so the 1, x 1, option is definitely worth the extra expense. The screen has plenty of detail and reasonably bright colour, whilst the matte anti-glare finish means that there is little problem with unwanted reflections in bright lighting.

XT3: The models are the D4x0 It aims to combine heavy-duty power with reasonable portability, and differs primarily from D8x0 series in screen size. All are two spindle designs, with a "D-bay" modular bay which can interchange optical drives, a second hard drive, floppy disk or a second battery.

All models have a smart card socket, PCMCIA socket, and 9-pin serial port, a "D-dock" port for docking station or port replicator, and have an internal socket for an The D and D share a common form factor, battery socket, and have a parallel printer port.

The D and D share a common form factor, battery socket, and do not have a parallel printer port. Both have support for an optional internal Bluetooth module, a socket for an optional mobile broadband card, and have an external switch for disabling any wireless connections.

It had a 14" screen, in regular non-widescreen form factor. Unlike later D6x0 series machines, both memory sockets were accessible from a single cover on the bottom of the system. Most, if not all Latitude models prior to the Latitude Dx20 series had a near-clone Inspiron, in the case of the D, it was the Inspiron M.

Differences include that the M does not work with the Dell D-Dock, and the case styling is slightly different. The motherboards, screens and hard drive caddies are all physically interchangeable. The hard drive is accessible through a cover on the left hand front side of the lower case and is secured by 1 screw.

After removing the screw, the hard drive can then slide out. For space saving purposes, instead of having both RAM chips on the bottom of the laptop, one RAM slot was moved to the top of the motherboard which could be accessed by removing the keyboard, whereas the other RAM slot remained in the area it had been located at previously.

Symptoms of this problem include a noise or whine when an audio device is connected to the audio-out jack. Up to this date Dell does not have a clear solution to this problem.

The D marked the transition from strictly bit processing to opening-up the potential to run bit operating-systems and applications. So depending on the installed processor, a D can run x bit software. It was initially sold with Intel integrated graphics, but an option to upgrade to a discrete Nvidia GPU became available after a few months.

It replaced the raised pointing stick with a "low profile" model, and introduced the option of 4-cell and 9-cell batteries in addition to the standard 6-cell model. The D has one mono speaker located in the base below the touchpad. It has no option to expand to stereo without using external speakers or headphones. There was no near-clone Inspiron model for the D The early models suffered from light bleeding, where a black screen would show light bleeding in from the bottom of the screen. In addition, some D screens are known for having bad LCD pixels.

Most Nvidia models will suffer from early failure of the graphics chip due to the switch to lead-free solder and "underfill" of the BGA. The computer industry at the time had just switched to lead free solders without redesigning cooling systems. This in turn led to undesirable heating cycles of the more brittle solder causing micro fractures to quickly form. They also have bad overheating problems. Latitude D[ edit ] Released in the D is an update of the D design. The optional nVidia graphics on this series of laptop are to be avoided due to overheating issues where the GPU would develop cracks in the solder.

This was mostly due to temperature fluctuation but the graphics chips also ran much hotter than they were meant to. The D series, despite having more room for cooling the chip, suffered from the same issue.

Unlike the D, the D only has one speaker. Latitude Dc[ edit ] The Dc was a slight variant model of the D, featuring a "manageable" version of the motherboard chipset unavailable on the standard D Unlike the D, the Dc model laptop could not be ordered with Intel graphics, it shipped only with the nVidia graphics chip.

As a result, all of the Latitude Dc laptops will eventually fail if used, that is, unless they have already failed previously. You can find some that originated in the United States, but those were special ordered over the phone.

As a result, not much information about specific chipsets, graphics chip options If there were any , or any other features can be found online for specifying details. Latitude D8x0 series[ edit ] The Latitude D8x0 series is the All are two spindle designs, with a "D-bay" modular bay which can interchange optical drives, a floppy module, a second hard drive, or a second battery. Latitude D running Windows 7 Professional. The D8x0 series models roughly parallel the technology in the D6x0 models other than for screen size; they do not share a battery form factor with the D6x0 series.

They were for all intents and purposes identical except for the graphics card, certification and in the case of the M70, the lid. There are even known cases of "mixed-mode" samples of the latter, where the Dell-recorded type according to the service tag and markings differs from the BIOS-reported type with an identical service tag. Both Latitude D and D have stereo speakers mounted on both sides of the keyboard.

Latitude D5x0 series[ edit ] The Latitude D series is a set of "entry level" business models; they are built on a 15" non-widescreen form factor, although models before the D were sold with both The Latitude D was also available, being the cheapest Latitude available at the time due to using AMD processors and cutting back on a few features.

It was essentially a D with no PC Card slot, no trackpoint, an option for a 14" screen If this was chosen it would have a similar wider bezel as on the earlier D5xx series machines , an AMD-based motherboard. Latitude D4x0 series[ edit ] Latitude D running Red Hat Enterprise Linux The D and D were 12" non-widescreen aspect ratio ultra-portable notebooks, roughly following the technology of the comparable generations of the series. The D and D are While the D8x0, D6x0 and D5x0 models were all introduced simultaneously with each generation, the D4x0 series were generally introduced a couple of months after their counterparts.

A robust design made it a favorite in harsher climates; however, this design lacked the visual appeal of many of its competitors. The modular bay could also be used for a second battery identical to the primary battery rather than a special modular bay battery. The ATG as well as the XFR have a protective glass glued on top of the screen that often has glue leaking onto the display causing air bubbles to form.

The Latitude XT was a touch-screen convertible-tablet computer. A large number of user reports suggest that the Dell Latitude XT suffers from a major problem. In addition, there have been reports that certain other drivers, such as iTunes Helper, may cause this or a similar problem. Other users report no problems from iTunes. According to the reports, this still leaves the dual sense but without Multi-Touch and other advanced features, "which render the auto and dual mode useless.

The digitizer will only start working again after consecutive reboots. A re-boot may solve the problem, but often users found that the driver installation is damaged, requiring a re-installation of the drivers. In this case, the alternatives are 1 restore the entire operating system from backup, 2 manually un-install by erasing all N-Trig programs and drivers then editing the registry to remove all references to N-Trig, then re-install the N-Trig software, or 3 do a complete re-install of Windows.

These problems have been reported both with XP and Vista, 32 and 64 bit. Most, but not all, users of the MediaBase report that it prevents the drivers from loading. A Class Action Lawsuit settlement by NVidia was reached where certain Dell models were provided with replacement motherboards at no expense.
