ThinkPad

ThinkPad is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand ThinkPad rather than just read about it. In short: ThinkPad is a line of business-oriented laptop and tablet computers produced since 1992. It was originally designed, created and manufactured by the American International Business Machines (IBM) Corporation.

Key takeaways

  • ThinkPad belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect ThinkPad to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of ThinkPad from memory before moving on to harder problems.

Reference excerpt

ThinkPad is a line of business-oriented laptop and tablet computers produced since 1992. It was originally designed, created and manufactured by the American International Business Machines (IBM) Corporation. IBM sold its PC business to the Chinese company Lenovo in 2005; since 2007, all ThinkPad models have been manufactured by Lenovo.

The ThinkPad line was first developed at the IBM Yamato Facility in Japan; they have a distinct black, boxy design, which originated in 1990 and is still used in some models. Most models also feature a red-colored trackpoint on the keyboard, which has become an iconic and distinctive design characteristic associated with the ThinkPad line. It has seen significant success in the business market while certain models target students and the education market. ThinkPad laptops have been used in outer space and for many years were the only laptops certified for use on the International Space Station (ISS). ThinkPads have also for several years been one of the preferred laptops used by the United Nations.

History Following the failure of the first laptop computer, the PC Convertible, IBM was the last of the major personal computer manufacturers to enter the fast-growing notebook market, launching the PS/2 Note in 1992. Building on the PS/2 Note, the ThinkPad was developed to compete with Compaq in the United States, whose LTE was the first commercially successful notebook PC; as well as Apple Computer's highly successful PowerBook, and Toshiba in Japan, whose Dynabook series of notebooks were similarly successful. IBM signed a lucrative contract with the Harvard Business School to provide the campus with notebook PCs. The task of creating a notebook was given to the Yamato Facility in Japan, headed by Arimasa Naitoh (内藤在正, Naitō Arimasa; Vice President of Lenovo's PC and Smart Devices business unit), a Japanese engineer and product designer who had joined IBM in the 1970s, now known as the "Father of ThinkPad".

The name "ThinkPad" was a product of IBM's corporate history and culture. Thomas J. Watson Sr. first introduced "Think" as an IBM slogan in the 1920s. With every minicomputer and mainframe IBM installed (almost all were leased – not sold), a plastic sign with the text "Think" printed on an aluminum plate was placed atop the operator's console. For decades, IBM had also distributed small notepads with the word "THINK" emblazoned on their cover to customers and employees. The name "ThinkPad" was suggested by IBM employee Denny Wainwright, who had one such notepad in his pocket. The name was opposed by the IBM corporate naming committee as all the names for IBM computers were numeric at that time, but "ThinkPad" was kept due to praise from journalists and the public.

Early models

In April 1992, IBM announced the first ThinkPad models, the 300, 700, and 700C all released on October 5, 1992. The 700T released in 1993 was a tablet computer. This machine was the first product produced under IBM's new "differentiated product personality" strategy, a collaboration between Richard Sapper and Tom Hardy, head of the corporate IBM Design Program. Development of the 700C also involved a close working relationship between Sapper and Kazuhiko Yamazaki, lead notebook designer at IBM's Yamato Design Center in Japan and liaison between Sapper and Yamato engineering. This 1990–1992 "pre-Internet" collaboration between Italy and Japan was facilitated by a special Sony digital communications system that transmitted high-res images over telephone lines. This system was established in several key global Design Centers by Hardy so IBM designers could visually communicate more effectively and interact directly with Sapper for advice on their projects. For his innovative design management leadership during ThinkPad development, Hardy was named "Innovator of the Year 1992" by PC Magazine. The first ThinkPad tablet, a PenPoint-based device formally known as the IBM ThinkPad 2521, was positioned as a developer's release. The ThinkPad tablet became available for purchase by the general public, as the 700T, in October of the same year. IBM marketed the ThinkPad creatively, through methods such as early customer pilot programs, numerous pre-launch announcements, and an extensive loaner program designed to showcase the product's strengths and weaknesses, including loaning a machine to archaeologists excavating the ancient Egyptian city of Leontopolis. The resulting report documented the ThinkPad's excellent performance under difficult conditions; "The ThinkPad is an impressive machine, rugged enough to be used without special care in the worst conditions Egypt has to offer." The positive critical and commercial reception of the ThinkPad played a key part in reversing IBM's fortunes. The first ThinkPads were very successful, collecting more than 300+ awards for design and quality.

Acquisition by Lenovo

In 2005, Lenovo purchased the IBM personal computer business and the ThinkPad as a flagship brand along with it. Lenovo founder Liu Chuanzhi said, "We benefited in three ways from the IBM acquisition. We got the ThinkPad brand, IBM's more advanced PC manufacturing technology and the company's international resources, such as its global sales channels and operation teams. These three elements have shored up our sales revenue in the past several years." Although Lenovo received the rights to use the IBM brand name for five years after acquiring IBM's personal computer division, it was only used for three years. By 2012, Lenovo was manufacturing and marketing Think-branded products, while IBM primarily handled servicing and repairs. At that time both IBM and Lenovo played a key role in the design of their "Think" branded products.

Worked examples

Example 1 — a first encounter with ThinkPad

Start with the simplest possible case. Write down what ThinkPad claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to ThinkPad before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about ThinkPad ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of ThinkPad

In research
ThinkPad appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses ThinkPad in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
ThinkPad is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2005 mergers and acquisitions, Business laptops, Computer-related introductions in 1992, so understanding it makes those chapters shorter.
In everyday life
Look for ThinkPad outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Why does ThinkPad matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
