Dell Latitude D520 Bluetooth Drivers Free Download Xp Install Update
Latitude is Dell's business laptop brand , designed and manufactured mainly by Compal and Quanta. 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 lines of Dell Latitude personal computers are currently in the "E" series, which is the successor to the popular Latitude D, C, and X series. In the past, the "mainstream" line was the 6 series, being the C6x0, D6x0, and E64x0 lines, but as of 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 Model numbers being along the lines of C8x0 or D8x0. The "budget" line was the 5 series, but as of 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.
The second number in the model As in, 5 4 70 or 7 2 80 indicates the size of the screen in the laptop. Budget models intended for education or home office environments, available in 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 as opposed to a magnetic latching system , DisplayPort video out as opposed to HDMI , 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.
Dell used the "E-series" name up through the models, and new models drop the "E. As of February , Latitude computers are available in three series: The series is designed to be entry-level, similar to the previous Latitude E55xx and Latitude E54xx laptops.
The series is mid-range, similar to the Latitude E64xx and E65xx. The series consists of high-end Ultrabook computers, introduced in with the Latitude E and E Aside from the , , and 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.
They are designed with extra durability in mind. The previous series is the Latitude D-series, on the Dx30 revision. 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 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.
These were Dell's first business-oriented notebooks based on the Pentium-M processor. 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. The D released in was an update of the D design; it used a slightly modified D chassis and a newer Pentium M chipset "Sonoma".
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. In March , Dell introduced the D and the D , its first business-oriented notebook with a dual core processor available.
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. All early D 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 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.
Released in the D is an update of the D design. It also had newer versions of the graphics processor options, support for Intel's "Turbo Memory" flash cache although this uses the same card slot as the mobile broadband card , and support for internal Wireless-N. 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. 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. It also could only be ordered with the Intel AGN wireless card, you couldn't order it with Dell's wireless options or lower end Intel wireless cards.
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 D as standard equipment in select international countries, but while not being that rare internationally, they didn't sell as many units as the D series And even Dc series laptops did. 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.
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. 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 and certification. 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. 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 D was Dell's last non-widescreen Latitude model.
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.
The D and D were 12" non-widescreen 4: 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. In a 22C deg ambient the D U processor has been measured to run from 62C deg at idle to 85C deg under heavy system loads, that is, within 10C deg of Intel's max.
C series laptops were notable for their consistent and interchangeable accessories across this wide range of processors. A robust design made it a favorite in harsher climates; however, this design lacked the visual appeal of many of its competitors. An interesting note on the C is that it was the last Dell notebook along with its sister models the Inspiron and Precision M50 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. 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. In July , Dell released multi-touch touch-screen drivers for the Latitude XT Tablet, claiming the "industry's first convertible tablet with multi-touch capabilities.
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. 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. But the install program will not un-install if it doesn't recognize the N-Trig hardware.
