Dell Alienware

Alienware was originally established to tap a niche in the high performance gaming market, which back then was not on the radar of the major PC manufacturers such as Dell. Since high-end hardware was not widely distributed, the company's founders formed an OEM which sold personal computers with the highest performing hardware and settings according to benchmarks. 

The company products are also differentiated by their science-fiction based designs.

Starting 2002, Dell considered buying Alienware, but did not take any action until March 22, 2006, when it agreed to purchase the company. 

The new subsidiary maintained its autonomy in terms of design and marketing. However, Alienware's access to Dell's supply chain, purchasing power, and economies of scale would lower its operating costs.

Initially, Dell maintained its competing XPS line of gaming PCs, often selling computers with the same specifications. The XPS line may have hurt Alienware's market share within its high-end market segment. Due to corporate restructuring in the spring of 2008, the XPS brand was scaled down.

Product development of gaming PCs was consolidated with Dell's gaming division, with Alienware becoming Dell's premier gaming brand. On June 2, 2009, The M17x was introduced as the First Alienware/Dell branded system. 

Alienware now represents the premium performance space in Dell’s consumer family of products. This launch also expands Alienware’s global reach from six to 45 countries.

On March 25, 2009, Alienware stated that it was considering closing its manufacturing bases in Athlone, County Westmeath, Ireland, and in Miami, Florida.

18 Inch

    M18x - Introduced in 2011, it is considered a replacement for the original M17x design, but with a bigger chassis and screen up to 18 inches, and special keyboard macros. It features Dual-GPU Support, and up to 32GB of RAM.

17 Inch

    M17x (Discontinued) - Introduced in 2009, it is the first laptop released by Alienware after the company was bought by Dell. The name and some of the design is based on the Alienware 17 inch laptop, the Alienware M17.

    M17x-R2 (Discontinued) - 2010 Revision of the M17x, adding support for Intel i5 and i7 processors.

    M17x-R3 - 2011 Revision of the M17x, changes from aluminium chassis to a simplified plastic design, 3D Ready through a 120 Hz screen. Removes Dual-GPU capability.

15 Inch

    M15x (Discontinued) - Introduced in 2009

    M15x-R2 (Discontinued) - 2010 Revision of the M15x, adding support for Intel i5 and i7 processors.

    M11x - First introduced in 2010, it is the smallest size gaming laptop from Alienware.

Dell Adamo

Adamo is a Dell subnotebook focused on design and mobility. A notebook prototype was unveiled at the Consumer Electronics Show on January 9, 2009.

Dell also claimed it is the "world's thinnest laptop", at 0.65 inches thick. It is a slim luxury ultraportable intended to compete with Apple's MacBook Air, Lenovo's ThinkPad X301, or HP's Voodoo Envy 133 laptop.

On September 9, 2009, Dell previewed a new, thinner Adamo "XPS" laptop design, which was 9.99 mm (0.39 inches) thick.

The Adamo 13 was released on March 17, 2009, in the US with a 1.4 GHz (or 2.1 GHz) Core 2 Duo processor, 2 GB (or 4 GB) of 800 MHz DDR3 memory, a 128 GB SSD(or 256 GB SSD), and a 13.4-inch widescreen with a 1366x768 resolution with a built-in 1.3 MP webcam and microphone. It weighs 4 pounds, ships with Windows 7 64-bit Home Premium, with an optional external DVD-RW drive.

Dell Adamo XPS

On September 9, 2009, Dell previewed a new, thinner Adamo XPS laptop design, which was 9.99 mm (0.39 inches) thick. It was released on November 5, 2009 and priced at (USD)$1,799. The laptop's bottom half, containing the keyboard, is smaller than the top half of the laptop containing the screen. 

The screen half is concave, so when shut the keyboard embeds itself into the screen. It is designed, that when open, the bottom of the screen half and the edge of the keyboard, make contact with the surface it is resting on. 

The Adamo XPS has a heat-sensing strip on the lip of its lid which, when touched, opens the lid. Internally, it has either a 128 GB solid-state drive or a 180 GB hard drive. It uses 4GB of DDR3 memory and a 1.4 GHz Intel ULV (ultra low voltage) processor. The battery can run either 4 or 5 hours, depending on configuration.

Dell Studio

Dell's Studio brand is a range of laptops and desktops targeted at the mainstream consumer market. The computers sit above Dell's Inspiron and below the XPS consumer lines in price and specifications. 

They differ from Dell's lower-end Inspiron models by offering slot-loading optical drives, media keys, more cover design options, faster processor options, HDMI and eSATA ports, LED-backlit screens, and backlit keyboards.

At launch, the Studio was offered in three models: the Studio 15 and the Studio 17 named after their respective screen size in inches, and the Studio Hybrid, named for its usage of laptop components in the form of an ultra small form factor desktop. 

If purchased online, many customizable colors, designs and features are available, including a finger print scanner in some countries.

On July 29, 2008, Dell introduced the desktop counterpart to the Dell Studio Laptops, the Dell Studio Hybrid PC. A compact desktop PC using laptop components, it contains the same slot-loading optical drive as the laptops with the range of connectivity (e.g., number of USB ports) expected of a desktop PC.

On September 24, 2009, Dell released Studio laptops with the options for a mobile Core i7 processor, although Pentium Dual-Core and Core 2 Duo options were still available as lower-end options.

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 (Pentium processors), CPi (Pentium II processors), CPx, C600 and C800 (Mobile Pentium III processors), CPt, C500 and C510 (Celeron processors), C400, C610 and C810 (Pentium 3-M processors) and C640 and C840 (Mobile Pentium 4M).

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:

    C840 cloned as the Inspiron 8200
    C810 cloned as the Inspiron 8100
    C800 cloned as the Inspiron 8000
    C640 cloned as the Inspiron 4150 and as the Inspiron 2650
    C610 cloned as the Inspiron 4100
    C600 cloned as the Inspiron 4000

An interesting note on the C840 is that it was the last Dell notebook (along with its sister models the Inspiron 8200 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. It used a Pentium 4M processor and DDR SDRAM. The Dell C840 also supports 2 gigabytes of ram.

Dell 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, 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 a 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.

The D600 (and simultaneously introduced D800) was Dell's first business-oriented notebook based on the Pentium-M processor; it 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 (non-widescreen) form factor. Unlike later D6x0 series machines, both memory sockets were accessible from a single cover on the bottom of the system.

Many Latitude models 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.

The D610 was an update of the D600 design; it used the same case design and very similar specs. The chipset was updated (to the "Sonoma" platform) and used DDR2 memory, and it used a second-generation "Dothan" Pentium M chips running on a 533 MT/s FSB (and available in higher speeds.) The location of one memory socket was moved to underneath the keyboard. The D610 was available with either an ATI Mobility Radeon X300 discrete GPU or Intel integrated graphics. It still continued to use a PATA hard drive and D-series modular bay.

Many Latitude models had a near-clone Inspiron, in the case of the D610, it was the Inspiron 610M.

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.

A number of Dell Latitude D610 units will develop microscopic fractures of the motherboard. Symptoms of this problem may include inability to turn on the computer, unexpected shut down within 30 seconds of being turned on, or visible screen artifacts while in operation. This problem also frequently contributes to the blue screen of death (BSOD) in Windows.

The Dell Latitude D610 was intended to have a 3-4 year life. After this period, some known issues include deterioration of CPU and other issues causing poor performance, especially with newer software.

The D620 (and simultaneously introduced D820) was Dell's first business-oriented notebook with a dual core processor available. Initially available with the interim "Yonah" Core Duo processors, it was sold with the first-generation mobile "Merom" Core 2 chips once those became available from Intel in the Fall of 2006; both run on a 667MT/s bus. 

It was initial sold only 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 (533 MHz) and PC2-5300 (667 MHz) memory.

Although the D620 is capable of accepting 4 GB of physical memory, but because of the limitation by the BIOS of a notebook (and not because the user is using a 32-bit or 64-bit OS), it will only see 3.5 GB of memory, or 3.3 with on board video (memory is shared). Using a 64-bit OS will not help the user to see all 4 GB of RAM on the D620.

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.
 
All early D620 models were known for faulty LCD screens. All of these 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, D820 and D830 were available with a Intel integrated GMA or Nvidia Graphics Card. All Nvidia models will suffer from early failure of the graphics chip due to defective solder and "underfill" of the BGA graphics core as it responds to thermal fluctuations. 

This is attributed to a faulty manufacturing on part of Nvidia which caused a multimillion recall not only of some Dell notebooks but also some HP, Compaq and Apple products Affected models. The failure manifests itself by stripes or "artifacts" on the LCD AND also an external screen or by the total absence of an image. 

There is no permanent fix for it and the early replacements by Dell included only the same but new faulty chips which will also fail eventually. So far only the models with the Intel graphics seem to have survived. 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. However all these chips will die eventually.

The D630 is an update of the D620 design. It differed most significantly in being based on the "Santa Rosa" (mobile 965) chipset, which supported the 800MT/s models of the mobile Core 2 Duo (both the Merom 7xx0 series and later the Penryn-based 8x00/9x00 series.) 

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. It also added a 4-pin Firewire IEEE1394 port. It uses DDR2 memory and is compatible with PC2-5300 (667 MHz) and PC2-6400 (800 MHz) memory will work, but at PC2-5300 speeds.

Unlike the D830, the D630 has non stereo speakers.

There was no near-clone Inspiron model for the D630.

The D630c was a slight variant model of the D630; it featured a "manageable" version of the motherboard chipset, and base configuration was slightly more powerful. Except for the chipset management, all of those "base features" were available as options on the regular D630.
