On this specific aspect of design guidelines, Apple pioneered the development of graphical interface guidelines with the launch of the Macintosh in the s which was promptly followed by Microsoft's Windows development team. Microsoft has one of the largest research centers in the personal computer and software industry and has invested more heavily in Internet-based interfaces over operating systems to date Hedgebeth, Apple's reliance on their loyal customer base and the development of online Internet panels to test new operating systems as was done thoroughly with the MacOS X
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. 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. Latitude D[ edit ] 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.
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.
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. They also have bad overheating problems. Latitude D[ edit ] 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 cardand 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.a) Dell’s build-to-order manufacturing and sales model changed the way companies buy computers.
