The ThinkPad X Series is a line of notebook computers and convertible tablets originally produced by IBM and now marketed by Lenovo.

IBM announced the ThinkPad X Series (initially the X20) in September 2000 with the intention of providing "workers on the move with a better experience in extra-thin and extra-light mobile computing." The ThinkPad X Series replaced both the 240 and 570 series during IBM's transition from numbered series to letter series during the early 2000s. The first X Series laptops were "slimmer than a deck of cards" and "lighter than a half-gallon of milk", despite the presence of a 12.1-inch Thin-film transistor (TFT LCD) display. These design values - thin and light - continued to be a part of the ThinkPad X Series laptops even after the purchase of IBM's Personal Computing Division by Lenovo. The first X Series ThinkPad released by Lenovo was the X41 in 2005.

The ThinkPad X Series laptops from Lenovo were described by Trusted Reviews as combining an ultraportable's weight and form factor with a durable design. The X Series laptops include traditional ultraportables, as well as convertible tablet designs. According to Lenovo, the ThinkPad X Series laptops include low power processors, offer long battery life, and offer several durability features such as a Roll Cage, magnesium alloy covers, and a spill-resistant keyboard.

2005

X41 Tablet

Three years after the release of the X30, upon acquiring the ThinkPad division, Lenovo released the ThinkPad X41 ultraportable laptop and the ThinkPad X41 Tablet. The X41 Tablet was convertible, with the capacity to function as a tablet PC and an ultraportable laptop.

X32

The X32 was introduced in 2005. The numbering system was a bit confusing, as it was actually introduced after the X40, but using the older X3x chassis design. It was also a bit more powerful than the X40 and X41 units, due to the use of faster full-voltage Dothan processors and standard 2.5" 5400/7200 RPM hard drives. It was a very short-lived model, discontinued within months after introduction. On this model, IBM included Gigabit LAN and the Security Sub System on all models. The X32 and X41 are one of the last IBM designed ThinkPads, before Lenovo took over. The X41 Tablet was designed by Lenovo.

2006

The X Series laptops released in 2006 from Lenovo were the X60, X60s, and X60 Tablet.

X60 and X60s

The X60 and X60s slimline differed primarily by their processors: the X60s had a low voltage processor, while the X60 did not. This gave the X60s a lower active temperature and longer battery life in exchange for reduced performance. The X60s also had a smaller heatsink and a thinner case with a different battery form factor, although it could use standard X60 batteries with a plastic adapter.

In its review of the ThinkPad X60/X60s, Notebook Review called the laptop "Hands down the best performing ultraportable on the market", while raising issues about the design and the lack of an optical drive.

The two laptops were available in a variety of different configurations. Later X60 models used 64-bit Core 2 Duo CPUs, and some X60s were available with a lightweight LCD panel. Typical specifications of the laptops are provided below:

• Processor: 1.66 GHz Intel Core Duo T2300E/ Core Solo 1.6 (X60) / L2400 (X60s)
• Operating System: Microsoft Windows XP Professional
• Storage: 80GB 5400RPM
• RAM: up to 2GB DDR2 SDRAM
• Display: 12.1"
• Graphics: Intel Media Accelerator 950
• Weight: starting at 1.64 kg (3.62 lb)

X60 Tablet

The ThinkPad X60 Tablet was praised by reviewers. LAPTOP Magazine said that the ThinkPad X60 Tablet "raises the bar for business-class convertibles". The most significant issue raised was the low capacity 4-cell battery, which provided a battery life of two hours.

2007

The X Series laptops released in 2007 from Lenovo were X61, X61s, and X61 Tablet.

X61

The X61 especially received mixed user reviews on CNET, with some claiming display problems, and delivery delays, while others praised the laptop for performance and portability.

Reviewers, however, praised the ultraportable. Notebook Review called it an "extremely fast ultraportable". The display contrast and view angles were criticized, and the palm rest which was prone to heating from the wireless card beneath it.

The specifications of the laptop are given below:

• Processor: From 1.8 GHz Intel Core 2 Duo T7100 to 2.5 GHz Intel Core 2 Duo T9300
• Chipset: Intel 965 Express
• RAM: from 512 MB to 4GB DDR2 PC5300 (8GB is unofficially supported)
• Storage: from 80GB to 160 SATA (any SATA HD or SSD will work, and via a BIOS mod it supports SATA-II)
• Screen: 12.1 inch LCD (from many not specified makers, and therefore different qualities)
• Graphics: Intel X3100
• Weight: starting at 1.41 kg (3.1 lb)

X61s

The X61s was praised for its good build quality, performance, and long battery life - the latter of which was an improvement over the X41.

The specifications of the laptop are given below:

• Processor: 1.6 GHz Intel Core 2 Duo L7500
• Chipset: Intel 965GM
• Memory: from 512 MB to 4GB DDR2 PC5300 (8GB is unofficially supported)
• Operating System: Microsoft Windows Vista Business 32 Bit
• Hard Drive: 100GB 7200RPM
• Screen: 12 inch
• Graphics Card: Intel X3100

X61 Tablet

The ThinkPad X61 Tablet also received positive reviews, with IT Reviews saying that "the build quality and engineering are second to none and this shines through with the Tablet features which have been executed with something close to genius". However, the high price and relatively low performance were criticized by the reviewer.

TabletPC Review acknowledged the sturdiness of the X61 Tablet, the high battery life, and the quality of the pen. The features that met with disfavor were the lack of a widescreen, display brightness and colors, and the lack of an optical drive - although the reviewer admitted that the absence helps reduce weight.

2008

The laptops released in the X series in 2008 followed the new naming conventions established by Lenovo. The X Series laptops released by Lenovo in 2008 were X200 and X300.

X200

The ThinkPad X200 was released in 2008. It leverages the new technology from the X300, including the options of a solid-state drive (SSD), an optional integrated camera, 12.1" widescreen display, optional 3G WWAN, a new 9-cell battery for extended running time up to 9.8 hours, weight as low as 1.34 kg (2.95 lb), and CPU up to 2.66 GHz Intel Core 2 Duo. The hardware specifications of the X200 are:

• Processor: Intel Montevina Platform, Core 2 Duo (Penryn Generation) from ULV version SU2300 (1.2 GHz) to 35 W TDP T9600 (2.8 GHz), many 25 W CPUs are also available (P8400, P8600, P8700, etc.)
• Memory: 8 Gigabyte RAM, maximum
• Display: Widescreen display, non-glossy (matte)
• Battery life: Up to 10 hours with a 9-cell battery
• Weight: 1.34 kg / 2.95 lb (with 4-cell battery), 1.47 kg / 3.24 lb (with 6-cell battery), 1.63 kg / 3.59 lb (9-cell battery)

The laptop features cooler components (made possible with the fan design modeled on owl-wings). However, the laptop did not have a touchpad (only the TrackPoint), no HDMI, DVI, or display port, and no built-in optical drive. The X200 series included Tablet PC models, designated by the usage of the "t" suffix, primarily of which was the X230T.

X200s

Lenovo released X200s in 2008. It differed from the standard X200 in being lighter, having longer battery life, and running more quietly due to an "owl fan" design for cooling taken from the X300. The X200s was available with more than half a dozen different CPUs and three screens, the top of the range of which was a WXGA+ LED.

X300 and X301

Codenamed "Kodachi", with X300 released on 26 February 2008. It is distinguished from other ultraportable laptops by its usage of LED backlighting, removable battery, solid-state drive, and integrated DVD burner. The ThinkPad X300 used a small form factor Intel GS965 chipset (instead of the standard GM965 chipset), along with the Intel Core 2 Duo L7100 low-voltage CPU (with 12 W TDP). Its successor, the ThinkPad X301 uses the Intel Centrino 2 mobile platform with GS45 chipset, and an ultra-low-voltage (ULV) CPU. It also integrates GPS, WWAN, and a webcam in the top lid. The thickest part of the laptop is 2.3 cm (0.92 in), while the thinnest part is 1.9 cm (0.73 in).

The X300's original internal codename was Razor, after the then popular flip phone from Motorola. Lenovo noticed that three technologies were converging that would make it possible to build a very thin, light, and fast ThinkPad. The first was solid-state storage, which would replace mechanical hard drives. The second was light-emitting diode (LED) backlighting for flat-panel displays which would improve battery life and image quality. The third was ultrathin optical drives just 7 mm thick, compared to 9.5 mm to 12.7 mm on other ThinkPads. The Razor concept was eventually merged with the Bento-Fly project and renamed Kodachi.

The price at the time of the review by Notebook Review was extremely high, and indicated to be out of range for all but corporate users. LAPTOP Magazine awarded the X300 laptop a score of 4.5 stars, among the highest for a ThinkPad X Series laptop.

The hardware specifications of the X300 are:

• Processor: 1.20 GHz Intel Core 2 Duo L7100
• Graphics: Intel X3100
• Operating System: Windows XP Professional
• Screen: 13.3-inch, LED-backlit display 1440×900
• Memory: 8 Gigabyte RAM, maximum
• Storage: SSD drive
• Optical Drive: Ultra-thin DVD Burner
• Dimensions: 310 mm × 230 mm × 19-23 mm (12.4 in × 9.1 in × 0.73-0.92 in)
• Weight: starting at 1.33 kg (2.93 lb)

The laptop was less than an inch thick, making it the thinnest ThinkPad available at the time. The X300 laptop offered a quick boot with SSD. It also offered a built-in optical drive, uncommon in thin and light notebooks. However, the laptop did not include an SD card reader, had no expansion dock capability, and no ExpressCard or PC Card slot.

X100e

The ThinkPad X100e was released in 2010, with Engadget calling the laptop "the perfect solution between a netbook and a larger 13- or 14-inch ULV ultraportable". Available in two colors (heatwave red and the traditional ThinkPad matte black) the design was compared to that of the Edge series which deviated from traditional ThinkPad design. The X100e, however, despite the choice of colors, retained the "angular edges and boxy build" which "scream traditional ThinkPad design".

X201 Tablet

The X201 Tablet, released in 2010, was criticized by Engadget for its lack of durability, protruding battery, and 33 mm (1.3-inch) thick body, while praised for its performance. Notebook Review had similar views about the X201 Tablet in terms of both performance and battery life while indicating that the display could have been improved.

2011

The ThinkPad X Series laptops released in 2011 by Lenovo were the X120e, X220, X220 Tablet and X1.

2012

The ThinkPad X Series laptops released in 2012 by Lenovo were the X1 Carbon, X131e, X230 and X230T (Tablet).

X1 Carbon

In early August 2012, Lenovo released the ThinkPad X1 Carbon. The X1 Carbon weighs 1.35 kg, has a battery life of roughly eight hours, and has a start-up time of less than 20 seconds. The X1 Carbon was first released in China due to the popularity of ThinkPads in that market.

The X1 Carbon features a solid-state drive (SSD) instead of a hard drive. The base model has 4 gigabytes of memory, an Intel Core i5-3317U processor, and a 128-gigabyte SSD. The most expensive model has an Intel Core i7 processor and a 256-gigabyte SSD. The X1 Carbon requires the use of a dongle to access wired Ethernet and some models include 3G cellular modems.

The X1 Carbon has a 14-inch screen with a resolution of 1600 by 900 pixels. The X1 Carbon weighs 1.36 kg (3.0 lb) and measures 331 by 226 by 19 mm (13.03 by 8.9 by 0.74 in). The X1 Carbon's case is made of light carbon-fiber and has a matte black finish. The Carbon is also marketed "as the thinnest 14" ultrabook."

In a review published for CNET, Dan Ackerman wrote, "At first glance, the ThinkPad X1 Carbon looks a lot like other ThinkPads, but in the hand it stands out as very light and portable. The excellent keyboard shows up other ultrabooks, and the rugged build quality is reassuring. With a slightly boosted battery and maybe a lower starting price, this could be a serious contender for my all-around favorite thin laptop."

Peter Bright wrote a disaparaging review for "Ars technica". He found the new X1 Carbon with the "Adaptive Keyboard" to be near perfect but unusable because the keyboard was so non standard when compared with that of a desktop, or the older Thinkpad T410s and Lenovo Helix keyboards. As a touch typist he despaired at the removal of the function keys, and the layout. He cited the repositioning of Caps Lock, replacing it with Home End, and that pretty much each little -finger key has moved.

In November 2012, Lenovo announced a touch-screen variant called the ThinkPad X1 Carbon Touch designed for use with Windows 8. Its display makes use of multi-touch technology that can detect simultaneous inputs from up to ten fingers. On the performance of the X1 Carbon Touch's SSD, Engadget states, "The machine boots into the [s]tart screen in 11 seconds, which is pretty typical for a Windows 8 machine with specs like these. We also found that the solid-state drive delivers equally strong read and write speeds (551 MB/s and 518 MB/s, respectively), which we noticed the last time we tested an Ultrabook with an Intel SSD."

X130e

A special edition laptop was provided for Australian Year 9 students as part of the Digital Education Revolution (DER) program in 2012.

X230 Tablet

The Thinkpad X230t (Tablet) replaced the earlier X220 Tablet. Docking Station compatibility: The Thinkpad X230t is not compatible with previous series 3 docking stations (4337 and 4338). It is only compatible with the UltraBase series 3 "slice base". The X230t has a touchscreen with stylus support whereas the X230 has no touchscreen.

2013

The ThinkPad X Series laptops released in 2013 by Lenovo were the X240, X140e and ThinkPad Helix (Convertible Tablet).

X240

The Thinkpad X240 replaced the earlier X230. Compared to the X230, the X240 changed from the higher wattage Intel Core CPUs labelled as "Mobile class", to the lower wattage CPUs labelled "ultrabook class".
