Other

2000-2004 also saw the introduction of the X20 (September 2000), X21, X22, X23, X24, X30, and X31. Processors ranged from the PIII (All models until the X31) through to the Pentium M in the X31/X32/X40 series.

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 X30/X31 chassis design. It was also more powerful than X40 and many X41 units, due to the use of faster full-voltage processors and standard 2.5" 5400/7200 RPM hard drives. It was a very short-lived model, discontinued within months after introduction.

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 are unofficially supported)

Storage: from 80GB to 160 SATA (any SATA HD or SSD will work, and via 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 i965M

Memory: from 512 MB to 4GB DDR2 PC5300 (8GB are 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.

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

The ThinkPad X300 was also released in 2008. 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.

However, the laptop did not include an SD card reader, had no expansion dock capability, and no ExpressCard or PC Card slot.
