ThinkPad Yoga (2013–current)edit

The ThinkPad Yoga is an Ultrabook-class convertible device that functions as both a laptop and tablet computer. The Yoga gets its name from the consumer-oriented IdeaPad Yoga line of computers with the same form factor. The ThinkPad Yoga has a backlit keyboard that flattens when flipped into tablet mode. This is accomplished with a platform surrounding the keys that rises until level with the keyboard buttons, a locking mechanism that prevents key presses, and feet that pop out to prevent the keyboard from directly resting on flat surfaces. Lenovo implemented this design in response to complaints about its earlier Yoga 13 and 11 models being awkward to use in tablet mode. A reinforced hinge was required to implement this design. Other than its convertible form factor, the ThinkPad Yoga retains standard ThinkPad features such as a black magnesium-reinforced chassis, island keyboard, a red TrackPoint, and a large buttonless trackpad.

ThinkPad Tabletedit

Released in August 2011, the ThinkPad Tablet is the first in Lenovo's line of business-oriented Tablets with the ThinkPad brand. The tablet has been described by Gadget Mix as a premium business tablet. Since the Tablet is primarily business-oriented, it includes features for security, such as anti-theft software, the ability to remotely disable the tablet, SD card encryption, layered data encryption, and Cisco Virtual Private Network (VPN).

Additionally, the ThinkPad Tablet is able to run software such as IBM's Lotus Notes Traveler. The stylus could be used to write notes on the Tablet, which also included software to convert this handwritten content to text. Another feature on the Tablet was a drag-and-drop utility designed to take advantage of the Tablet's touch capabilities. This feature could be used to transfer data between USB devices, internal storage, or an SD card.

Slashgear summarized the ThinkPad Tablet by saying, "The stylus and the styling add up to a distinctive slate that doesn't merely attempt to ape Apple's iPad."

ThinkPad Tablet 2edit

In order to celebrate the 20th anniversary of the ThinkPad, Lenovo held a large party in New York where it announced several products, including the Tablet 2. Lenovo says that the ThinkPad Tablet 2 will be available on 28 October 2012 when Windows 8 is released. The ThinkPad Tablet 2 runs the Windows 8 Professional operating system. It will be able to run any desktop software compatible with this version of Windows.

The Tablet 2 is based on the Clover Trail version of the Intel Atom processor that has been customized for tablets. The Tablet 2 has 2 gigabytes of RAM and a 64 GB SSD. The Tablet 2 has a 10.1-inch IPS display with a 16:9 aspect ratio and a resolution of 1366 × 768. In a preview, CNET wrote, "Windows 8 looked readable and functional, both in Metro and standard Windows-based interfaces." A mini-HDMI port is included for video output. An 8-megapixel rear camera and a 2-megapixel front camera are included along with a noise-canceling microphone in order to facilitate video conferencing.

ThinkPad 8edit

Announced and released in January 2014, the ThinkPad 8 is based on the Intel's Bay Trail Atom Z3770 processor, with 2 GB of RAM and up to 128 GB of built-in storage. ThinkPad 8 has an 8.3-inch IPS display with a 16:10 aspect ratio and a resolution of 1920 × 1200 pixels. Other features include an aluminum chassis, micro-HDMI port, 8-megapixel back camera (with flash), and optional 4G connectivity. It runs Windows 8 as an operating system.

ThinkPad 10edit

Announced in May 2014, Lenovo ThinkPad 10 is a successor to the ThinkPad Tablet 2 and was scheduled to launch in the summer of 2014 along with accessories such as a docking station and external detachable magnetic keyboards. It used Windows 8.1 Pro as its operating system. It was available in 64 and 128 GB variants with 1.6 GHz quad-core Intel Atom Baytrail processor and 2 GB or 4 GB of RAM. It optionally supported both 3G and 4G (LTE). Display resolution was announced to be 1920 × 1200, paired with a stylus pen.

ThinkPad X1 Tabletedit

The ThinkPad X1 Tablet is a fanless tablet powered by Core M CPUs. It is available with 4, 8 or 16 GB of LPDDR3 RAM and SATA or a PCIe NVMe SSDs with up to 1 TB. It has a 2160 × 1440 IPS screen and supports touch and pen input.

ThinkPad 11e (2014–current)edit

The ThinkPad 11e is a "budget" laptop computer for schools and students with an 11-inch screen and without trackpoint. 11e Yoga is a convertible version of 11e.

E Series (2011–current)edit

The E Series is a low-cost ThinkPad line, designed for small business mass-market requirements, and currently contains only a 14" and 15" sub-lines. The E Series line of laptops replaced Lenovo's Edge Series, but somewhere (in some countries) currently (May 2019) offered as both of "Thinkpad Edge/E series" names.

L Series (2010–current)edit

The L Series replaced the former R Series, and is positioned as a mid-range ThinkPad offering with mainstream Intel Core i3/i5/i7 CPUs. The L Series have 3 sub-lines, the long-running 14" and 15.6" (and as launched this line had two models, L412 and the L512 in 2010); and as of 2018 there is also a 13" L380 available, which replaces the ThinkPad 13.

The main difference between the E Series and L Series is a basic MIL-STD-810 certification for L Series ThinkPads.

T Series (2000–current)edit

The T Series historically had high-end features, such as magnesium alloy rollcages, high-density IPS screens known as FlexView (discontinued after the T60 series), 7-row keyboards, screen latches, the Lenovo UltraBay, and ThinkLight. Models included both 14.1-inch and 15.4-inch displays available in 4:3 and 16:10 aspect ratios.

Since 2012, the entire ThinkPad line was given a complete overhaul, with modifications such as the removal of separate buttons for use with the TrackPoint (**40 series - 2014, then reintroduced **50 series - 2015), removal of separate audio control buttons, removal of screen latch, and the removal of LED indicator lights. Models starting from the **40 series featured a Power Bridge battery system, which had a combination of a lower capacity built-in battery and a higher capacity external battery, enabling the user to switch the external without putting the computer into hibernation. However, beginning with the 2019 **90 series models, the external battery was removed in favor of a single internal battery. Also, non-widescreen displays are no longer available, with 16:9 aspect ratio as the only remaining choice.

The most famous T-Series ThinkPad is the Tx20 Series of ThinkPad. The Laptops came in two editions: 15"(T520) or a 14"(T420). These ThinkPads are widely known to be the last ThinkPads to use the classic 7-row keyboard. Even though Enterprises and Governments have mostly phased out this 2011 ThinkPad, this is still one of the most popular models with I.T users (T-Series or Otherwise.) The Tx20 line of laptops is also known for its outstanding Linux compatibility.

Over time, The T-Series ThinkPad's purpose has changed. Initially, the T-Series ThinkPad was meant to have high-end business features and carry a 10-20 percent markup over the other ThinkPads. Starting with the T400, The ThinkPad T-Series became a less of a high-end business laptop and became more suited as a mobile workstation, becoming similar to the W-Series or P-Series ThinkPads. Achieving similar performance to the W-Series, but with a 5-10 percent smaller profile than the W-Series ThinkPads. In 2013, the T440 introduced another major shift in The ThinkPad T-Series. The ThinkPad became more of an overall office machine than a mobile workstation. By today's standards, The ThinkPad T-Series is thicker than most of its competitors.

X Series (2000–current)edit

The X Series is the main high-end ultraportable ThinkPad line, offering a lightweight, highly portable laptop with moderate performance. The current sub-lines for the X series includes:

• 13" X13 (mainstream);
  • X13 Yoga (convertible sub-line),
• 14" X1 Carbon (premium sub-line),
  • X1 Yoga (premium convertible sub-line), and
• 15" X1 Extreme (premium sub-line).

The daughter line includes the X1 Tablet (not to be confused with the 2005-2013 X Series tablets).

The mainstream current "workhorse" models is a X13 and X13 Yoga, the 13" successors of the classic discontinued 12" line of Lenovo X Series ThinkPads.

The premium 14"/15" thin-and-light line were the 13.3" ThinkPad models (the X300/X301) with ultrabay CD-ROM and removable battery, but are now replaced by the modern premium X1-series ultrabook line, such as the X1 Carbon, X1 Yoga, and X1 Extreme sub-series.

Discontinued mainstream lines such as the 12" X200(s), X201(s), and X220 models could be ordered with all of the high-end ThinkPad features (like Trackpoint, ThinkLight, a 7-row keyboard, a docking port, hot-swappable HDD, solid magnesium case and optional slice battery). The discontinued 12.5" X220 and X230 still featured a roll cage, a ThinkLight, and an optional premium IPS display (the first IPS display on a non-tablet ThinkPad since the T60p), but the 7-row keyboard was offered only with the X220. However, it lacked the lid latch mechanism which was present on the previous X200 and X201 versions. The discontinued slim 12" line contained only X200s and X201s with low power CPUs and high resolution displays, and X230s with low power CPUs. The 12.5" X series ThinkPads (such as X240 and later) had a more simplified design, and last 12" X280 model had only the Trackpoint feature, partially magnesium case and simplified docking port.

The obsolete low-cost 11.6" (netbook line) X100e and X120e were are all plastic, lacking both the latch and the ThinkLight, and using a variant of the island keyboard (known as chiclet keyboard) found on the Edge series. The X100e was also offered in red in addition to blue, and white in some countries. Those were more like high-end netbooks, whereas the X200 series were more like full ultraportables, featuring Intel Core (previously Core 2 and Celeron) series CPUs rather than AMD netbook CPUs.

The X Series with "tablet" suffixes is an outdated variant of the 12" X Series models, with low voltage CPUs and a flip-screen tablet resistive touchscreen. These include the traditional ThinkPad features, and have been noted for using a higher quality AFFS-type screen with better viewing angles compared to the screens used on other ThinkPads.

P Series (2015–current)edit

The P Series line of laptops replaced Lenovo's W Series and reintroduced 17" screens to the ThinkPad line. The P Series (excluding models with 's' suffix) is designed for engineers, architects, animators, etc. and comes with a variety of "high-end" options. All P Series models come included with fingerprint readers. The ThinkPad P Series includes features such as dedicated magnesium roll cages, more indicator LED lights, and high-resolution displays.
