Dell Latitude


Latitude is Dell's business laptop brand, designed and manufactured mainly by Compal and Quanta. The Latitude competes with the ThinkPad series from Lenovo, the EliteBook series from HP and TravelMate series from Acer. The "Rugged ", "XFR" and "ATG" models compete primarily with Panasonic's Toughbook line of rugged computers.

Overview and product type

The Dell Latitude is a laptop family from Dell Computers, intended for business use. By contrast, the Dell Inspiron is aimed at the consumer market and its specifications change regularly. Whereas Inspiron may change vendors or components several times over the course of a single model, the Latitude line generally retains identical components throughout its production. This design is intended to simplify maintenance and support tasks for large corporations, allowing components to be easily swapped between models.
The Dell Latitude series have dropped the initial alphabet in newer model types, and became the successor to the popular Latitude E, D, C, and X series. The Latitudes from the early 1990s up until the C*00 lines weren't in a set "series", instead of going under the models CP and XP with modifiers at the end, e.g.: XPi, CP M233.
In the past, the "mainstream" line was the 6 series, being the C6x0, D6x0, and E64x0 lines, but as of 2015 this line has been discontinued and replaced by both the 5 series and the 7 series. The 15" "Premium" line was the 8 series, until the E-series merged this line with the 6 series. The "budget" line was the 5 series, but as of 2015 the 5 series and 7 series Latitude laptops are the primary lines of Latitude laptops. The 3 series has replaced the 5 series as the budget line. Dell has also since dropped the E from the Latitude line, and the models are delineated by number now, e.g.: Latitude 5480, 5570. The second number in the model indicates the size of the screen on the laptop.
The current Dell Latitude lineup is as follows:
Latitude 3xxx series. Budget models intended for education or home office environments, available in 13.3"/14"/15.6" trims.
Latitude 5xxx series. Mainstream line, available in 11.1"/12.5"/13.3"/14"/15.6" trims.
Latitude 7xxx series. Premium "ultrabooks", available in 12.5"/13.3"/14" trims only.Latitude computers are also differentiated in their feature sets, due to their business focus. For example, they often include security features such as smartcard and contactless smartcard, and TPM security, which are not needed by most consumers. A lid clasp, DisplayPort video out, and support for legacy standards are all results of the requirements of the business market.
Some models also have the capability of Latitude ON which can be selected during the configuration of the laptop. Latitude ON is essentially a system within a system. It requires a separate add on module which contains its own microprocessor and Operating system. This allows the laptop to function in the realm of a Netbook.

Current models

.
Dell used the "E-series" name up through the 2016 models, and new 2017 models drop the "E." and Dell E-Port Replicator with it. As of February 2017, Latitude computers are available in three series: the 3000, 5000, and 7000. The 3000 series is designed to be entry-level, similar to the previous Latitude E55xx and Latitude E54xx laptops. The 5000 series is mid-range, similar to the Latitude E64xx and E65xx. It includes a high-performance subseries whose model designations end in 1. These devices are available with higher-TDP processors, discrete graphics and NVMe SSDs. The 7000 series consists of high-end Ultrabook computers, introduced in 2014 with the Latitude E7440 and E7240.
Aside from the 3000, 5000, and 7000 series, Dell also provides an Education and Rugged Series of Latitude computers. The Education series laptops are designed for use in educational institutions. They're not especially powerful, and are more geared towards office applications or internet-based applications. The Rugged series laptops are similar to the previous Latitude XFR computers. They are designed with extra durability in mind.

xx90 Models (2018)

The previous series is the Latitude D-series, on the Dx30 revision. The models are the D4x0, D5x0, D6x0 and D8x0 most models are based on the Intel Core 2 Duo and the Intel Santa Rosa chipset, with the exception being the D531. Ever since the D420, D620, and D800, the D-series features wide-aspect LCD screens: 12.1", 14.1", and 15.4" respectively.

Latitude D6x0 series

The Latitude D6x0 series is the 14"/14.1" corporate model. 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, a 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 a docking station or port replicator, and have an internal socket for an 802.11 wireless card.
The D600 and D610 share a common form factor, battery socket, and have a parallel printer port.
The D620 and D630 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.

Latitude D600

The D600 was released on 3/12/2003. These were Dell's first business-oriented notebooks based on the Pentium-M processor. The Latitude D600 series used the first-generation "Banias" or Dothan Pentium M chips running on a 400 MT/s FSB on DDR memory. It had a PATA hard drive and a D-series modular bay, and used an ATI Radeon 9000 GPU. It had a 14" screen, in regular 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 D600, it was the Inspiron 600M. Differences include that the 600M 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 Latitude D600 used a PA-10/PA-12 charger and came with a DVD drive, 2 x USB, 1 x TV, 1 x network, 1 x parallel, 1 x serial, and 1 monitor output. 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.

Latitude D610

The D610 was an update of the D600 design; it used a slightly modified D600 chassis and a newer Pentium M chipset. This chipset was the first Intel mobile chipset to use DDR2 Memory, versus the DDR in the Latitude Dx00 series. 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. Unlike the D600 and prior midrange Latitudes you had a choice of standard integrated Intel Graphics, or a discrete ATI solution.
Latitude D610 Audio-Out "whining"
Some Dell Latitude D610 units with a dedicated ATI X300 graphics card seem to have problems with the audio-out jack. 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.

Latitude D620

In March 2006, Dell introduced the D620, its first business-oriented notebook with a dual-core processor available. The D620 marked the transition from strictly 32-bit processing to opening-up the potential to run 64-bit operating systems and applications. Initially available with the interim "Yonah" Core Duo processors, it was later sold with the first-generation mobile "Merom" Core 2 processor once those became available from Intel in the Fall of 2006; both run on a 667MT/s bus. So depending on the installed processor, a D620 can run x86-64 64-bit software. The D620 used a Socket-M for its motherboard and its CPU is possible to be upgraded. 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. It uses DDR2 memory and is compatible with both PC2-4200 and PC2-5300 memory.
Although the D620 accepts a maximum of 4 GB of physical memory, it cannot be used fully, because of the 32-bit physical addressing limitation of the 945 Core 2 mobile chipsets ,, restricts the usable memory by the operating system to 3.5 GB, or 3.3 GB with onboard video.
The D620 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 D620.
Latitude D620 problems
All early D620 models were known for faulty LCD screens. The early models suffered from light bleeding, where a black screen would show light bleeding in from the bottom of the screen. This wasn't fixed until almost a year into production. In addition, some D630 screens are known for having bad LCD pixels.
The D620/D630 and D820/D830 were available with an Intel integrated GMA or Nvidia graphics chip. 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. NVIDIA was found liable for these failures, causing a multimillion-unit recall, not only of some Dell notebooks, but also some HP, Compaq, and Apple products. The failure manifests itself by stripes or "artifacts" on the LCD AND also an external screen or by the total absence of an image.
Dell tried to prolong the lifetime of the Nvidia chips with a BIOS update which causes the fan to run more continuously and thus reduce the strain from repeated heating/cooling cycles on the graphics chip.
They also have bad overheating problems.

Latitude D630

Released in 2007, the D630 is an update of the D620 design. It differed most significantly in being based on the newer "Santa Rosa" chipset, which supported the 800MT/s models of the mobile Core 2 Duo It also had newer versions of the graphics processor options, support for Intel's "Turbo Memory" flash cache, and support for internal Wireless-N. It also added a 4-pin Firewire IEEE1394 port. It uses DDR2 memory and is compatible with PC2-5300, and PC2-6400 memory will work at PC2-5300 speeds.
The optional Nvidia graphics on this series of laptops 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 D830 series, despite having more room for cooling the chip, suffered from the same issue.
The D630 unofficially will accept a maximum of 8 GB of physical memory, however, a BIOS update is required.
Unlike the D830, the D630 only has one speaker.

Latitude D630c

The D630c was a slight variant model of the D630, featuring a "manageable" version of the motherboard chipset unavailable on the standard D630.
Unlike the D630, the D630c model laptop could not be ordered with Intel graphics, it shipped only with the Nvidia graphics chip. As a result, all of the Latitude D630c laptops will eventually fail if used, that is, unless they have already failed previously.
It also could only be ordered with the Intel 4965AGN wireless card, you couldn't order it with Dell's wireless options or lower end Intel wireless cards.

Latitude D631

The Latitude D631, similar to the D531, was a variant of the Latitude Dx30 series that had AMD processors instead of Intel. However, it is very rare inside the United States due to it not being an option to order on Dell's website. You can find some that originated in the United States, but those were special ordered over the phone. They were sold alongside the D630 as standard equipment in select international countries, but while not being that rare internationally, they didn't sell as many units as the D630 series laptops did. As a result, not much information about specific chipsets, graphics chip options, or any other features can be found online for specifying details.

Latitude D8x0 series

The Latitude D8x0 series is the 15.4" corporate model; unlike the D600 and D610, all feature a widescreen form factor. 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. 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 802.11 wireless card.
The D800 was Dell's first widescreen Latitude notebook.
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. The D820 and D830 add an ExpressCard socket, not available in the D6x0 series. The D830 is capable of accepting 8 GB of physical memory with updated firmware.
The D800 equated to the Precision M60, and the D810 to the Precision M70. They were for all intents and purposes identical except for the graphics card, certification, and in the case of the M70, the lid.
The near-clone Inspirons for the D800 and D810 were the Inspiron 8500 and 8600; the D820 and D830 share hardware with Precision models M65 and M4300 respectively. 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 D820 and D830 have stereo speakers mounted on both sides of the keyboard.

Latitude D5x0 series

The Latitude D500 series is a set of "entry-level" business models; they are built on a 15" non-widescreen form factor, although models before the D530 were sold with both 14.1" and 15" screens They are 2-spindle devices, and roughly follow the technical generations of the D6x0 and D8x0 series. The D530 was Dell's last non-widescreen Latitude model.
The Latitude D531 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 D830 with no PC Card slot, no Trackpoint, an option for a 14" screen, an AMD-based motherboard. DVD Drives, Screen Assemblies, RAM, and Hard Drives/Caddies were interchangeable.

Latitude D4x0 series

The D400 and D410 were 12" non-widescreen ultra-portable notebooks, roughly following the technology of the comparable generations of the series. The D400 had a design that was similar to the D610 and came with a ULV Pentium M. The D410 came with a ULV Pentium M.
The D420 and D430 are 12.1" widescreen ultra-portable notebooks. The D420 came with either an Intel Core Solo U1300 ULV 1.06 GHz, Intel Core Duo U2400 ULV 1.06 GHz or Intel Core Duo U2500 ULV 1.2 GHz. Unlike its bigger D620 brother, the D420's CPU was a soldered-in BGA and therefore is not up-gradable. The D430 came with either an Intel Core Solo U1400 ULV 1.2 GHz or Intel Core 2 Duo U7600 1.2 GHz; the U7700 Processor was later made available as an option.
and a D410 running Windows XP.
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. Also, since they use ULV processors and chipsets, and are generally less powerful, the technology does not correspond as closely as it does between other models in each generation — for example, the D420 uses the parallel ATA hard drive rather than the SATA interface in the D520/620/820.
In a 22C° ambient the D430 U7700 processor has been measured to run from 62C° at idle to 85C° under heavy system loads, that is, within 10C° of Intel's max. temperature rating for the processor. The D4x0 series has been replaced by the E4200 model.

Latitude C series

The Latitude C-series notebooks covered the range of processors from the Pentium 166 MHz to the Pentium 4-M. Models in this series included the CP, CPi, CPx, C600 and C800, CPt, C500 and C510, C400, C610 and C810 and C640 and C840.
C series laptops were notable for their consistent and interchangeable accessories across this wide range of processors. The series was one of the first to offer the UXGA 1600x1200 resolution display and included a NVidia GeForce MX400 32 MB video accelerator to complement the display requirements. A robust design made it a favorite in harsher climates; however, this design lacked the visual appeal of many of its competitors.
The most popular of the C-series included the C800, C810, C840, and later the C640.
The later C-series models mostly had near clones sold as the Inspiron 4000 and 8000 series:
An interesting note on the C840 is that it was the last Dell notebook to have both a "fixed" optical drive as well as a modular bay, making it a "three-spindle" notebook. The modular bay could also be used for a second battery identical to the primary battery rather than a special modular bay battery. It used a Pentium 4-M processor and DDR SDRAM.
The Dell C840 can support up to one gigabyte of RAM in each of two slots, for a total of two gigabytes in all. The GPU can also be upgraded on the C840/M50/i8200, from a GeForce2 Go to the Quadro4 Go 700 from the Precision M50.

Other models

The Latitude ATG was a semi-rugged version of the D620, and was Dell's only semi-rugged offering, while their fully rugged offering originally consisted of the Augmentix XTG630, a D630 in a fully rugged case, and later the D630 XFR. 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.

Latitude XT

The Latitude XT was a touch-screen convertible-tablet computer.

Latitude XT problems

In July 2008, Dell released multi-touch touch-screen drivers for the Latitude XT Tablet, claiming the "industry's first convertible tablet with multi-touch capabilities." Dell has partnered with N-trig, providers of DuoSense technology, combining pen, capacitive touch and multi-touch in a single device. N-trig's DuoSense dual-mode digitizer uses both pen and zero-pressure capacitive touch to provide a true hands-on computing experience for mobile computers and other digital input products over a single device.
A large number of user reports suggest that the Dell Latitude XT suffers from a major problem. The N-Trig digitizer interfaces to the XT by an internal USB port. Users report that any other USB device which is plugged in may, and usually does, prevent the N-Trig applet from identifying the N-Trig hardware. 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." There have also been reports that the driver may crash, catastrophically or non-catastrophically, leaving no screen input at all. A re-boot may solve the problem, but often users found that the driver installation is damaged, requiring a re-installation of the drivers. But the install program will not un-install if it doesn't recognize the N-Trig hardware. In this case, the alternatives are restore the entire operating system from backup, 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 do a complete re-install of Windows.
These problems have been reported both with XP and Vista, 32 and 64 bit. In addition, Dell sells a MediaBase with an internal DVD drive. The drive also interfaces by way of a USB connection inside the MediaBase. Most, but not all, users of the MediaBase report that it prevents the drivers from loading.

NVidia GPU problems

Many D620/D630 and D820/D830 models with NVidia mobile GPUs may experience graphics failure. A Class Action Lawsuit settlement by NVidia was reached where certain Dell models were provided with replacement motherboards at no expense.

Recall affecting D Series batteries

Dell posted notices to many of their laptop customers on August 14, 2006, saying that the Sony batteries on the D410, D500, D505, D510, D520, D600/D610, D620, and D800/D810 models were prone to bursting into flames, or even exploding.
The batteries on any of these computers purchased between April 2004 and July 18, 2006 were supposed to be removed and the computers run on AC power until replacements arrived. Problematic Sony batteries led to battery recall programs at other laptop companies, including Hitachi, Toshiba, Lenovo and Apple.
