The name "ThinkPad" was inspired by IBM's Pad. Every employee of IBM or anyone who goes to the IBM training center for training will get a pad with the motto "think" printed on it. At a meeting to discuss the product name of portable computer, a participant casually threw a notebook like this into the air and left it on the conference table. Inspired by this, another participant suggested using the name "ThinkPad". At first, IBM executives objected to the use of this name because IBM has always used numbers to identify product models. However, the name "ThinkPad" was greatly welcomed and loved by employees and customers. Finally, IBM executives compromised and agreed to use "ThinkPad" as the product name.
The design of ThinkPad is inspired by the traditional Japanese lunch box.
The original design work of ThinkPad was undertaken by IBM's Daiwa Design Center in Japan. The pure black appearance of ThinkPad is inspired by the traditional Japanese painted lunch box, SH Cadbent, which is an all-black lunch box and is usually used for holding lunch.
IBM began to release ThinkPad products in 1992, including ThinkPad 700. The original ThinkPad did not have a keyboard and should belong to the category of tablet computers. It is equipped with a black-and-white liquid crystal display (LCD), a 40 MB flash memory instead of a hard disk drive, a PenPoint OS operating system based on Go and a handwriting recognition system developed by IBM. Subsequently, IBM released a keyboard ThinkPad with Microsoft Windows 3. 1 pre-installed, with a price of US, 350, a weight of 3 kg (6.5 l pounds) and a size of 2.2×1.7× 8.3 inches (56× 297× 2/kloc-). It is also equipped with the largest 10.4 inch (264 mm) LCD screen, 25 MHz 386SX CPU, 120 MB hard disk and a keyboard with TrackPoint pointing stick. The bright red TrackPoint is installed on the keyboard, so people can conveniently use the portable computer on the aircraft cabin bracket without a bulky mouse.
Although the ThinkPad designed with a lithographic computer was not successful in business, it, together with Apple Newton***, initiated the era when people used PDA (Personal Digital Assistant) and mobile computing.
ThinkPad series classification
The following is a list of all ThinkPad series in recent years
ThinkPad A series: it means "all-in-one machine" and is bulky. It has three drive slots, two of which are replaceable. Some models ending in "P" are the first to use 15 inch UXGA "FLXView" LCD technology in ThinkPad. The series was discontinued in 2002.
ThinkPad G series: desktop replacement model, using desktop processor, with large weight, large volume and short battery life. The series was discontinued in 2005.
ThinkPad i series: low-priced low-end models, manufactured by third-party manufacturers (such as Acer and Great Wall) under the technical authorization of IBM. This series was discontinued on 200 1.
ThinkPad R series: I series and A series are merged to form R series, with two built-in drivers, one of which can be replaced. The low-end models inherit the tradition of I series and continue to take the low-cost road. The other models are designed as "mobile workstations" to replace the discontinued A series.
ThinkPad S series: Subnotebook, quite small and light, only sold to the Japanese market.
ThinkPad T series: the flagship model of ThinkPad, which is quite thin and high-end business model. There are two internal drives, one of which is replaceable.

ThinkPad Z series: Lenovo's first series, the first widescreen notebook, and the first ThinkPad specially designed for entertainment since it acquired IBMPC's PC division in 2005.
ThinkPad model details
ThinkPad 235
Model 2607, used only for ThinkPad 235 in Japan, is an interesting product, which is the follow-up product of IBM/ Ricoh RIOS. Also known as Clavius or Chandra2, it contains unusual features, such as three PCMCIA slots and the use of dual camera batteries as power supply. It adopts Intel Pentium MMX 233 MHz CPU, supports up to 160 MB of EDO memory, and has a built-in 2.5-inch hard disk supporting UDMA. Hitachi marketed Chandra2 as Prius Note 2 10.
ThinkPad 300 series
300 series (300, 3 10, 350, 360, 365, 380, 385, 390 (all with different sub-series)) is a long-term value-added series, from 486SX-25 to Pentium III 450. They are slightly larger and slower than the more versatile models, but they are cheaper.
ThinkPad 500 series
500 series (500,510,560 (e, x, z), 570(E)) is the main line of ultra-portable ThinkPads S. From 486 sx2-50 Blue lighting to Pentium III 500, these machines have only one onboard hard disk. Any other drive is external (or in the ultrabase of the 570).
ThinkPad 600 series
Series 600 (600, 600E and 600X) is the direct predecessor of T series, which is famous for its portability and sturdy structure. The 600 series packs 12. 1 inch SVGA or 13.3 inch XGA TFT LCD, Pentium MMX, Pentium II or III processor, full-size keyboard and optical tray into a package weighing about 2.3 kilograms (5 pounds). IBM can make this light and full-featured machine by using light but strong carbon fiber composite plastic.
ThinkPad 700 series
The 700 series (700, 70 1, 730 (tablet computers), 750, 755, 760, 765, 770 (many of which have sub-models)) are based on Intel's cutting-edge ThinkPads S. They had the best screen, the biggest hard disk and the fastest processor.
70 1 is nicknamed "butterfly" because its keyboard is divided into two parts to adapt to a smaller space. When it is collected, it will move up and down into the computer, and when it is opened, it will spread left and right, just like a butterfly spreading its wings.
ThinkPad 800 series
The uniqueness of Power PC ThinkPad series (800/820/821/822/823/850/851/860) is that they run on Power PC architecture instead of x86 architecture. They all use PowerPC 603e CPU with the speed of 100MHz, and the 860 model is 166MHz. 800 may use 603, it is not clear whether 800 is experimental. All units use SCSI 2 instead of IDE. It is believed that these devices are very expensive, and the price of 850 is over $1,000. The 800 series can run Windows NT 3.5 (or maybe 4.0), OS/2, AIX 4. 14, Solaris Desktop 2.5.1powerpc Edition, and possibly Linux.
ThinkPad Transnote
IBM Transnote is a pen-based notebook computer. Data can be entered through a keyboard, a tracking point, a paper notepad (with a writing sensor underneath), or on the screen through a stylus. This ThinkPad extends IBM's previous notebook computers (360P(E), 730T(E) and 755 P).

Lenovo Super Bay
UltraBay is Lenovo's name for interchangeable drive slots. This technology was introduced on the 750 series ThinkPad, and almost every generation of ThinkPad has undergone a redesign, which may lead to some confusion. I hope it can be clarified here. The following table summarizes the different UltraBay types, which models they appear in and which drives they can use. Please note that the optical drive bracket in G series ThinkPads is not UltraBay, because the drive is fixed and cannot be disassembled.
In terms of media, different UltraBays are related to the shape of the drives they accept; For example, the early A, T and X series models can accept UltraBay equipment with the thickness as high as 12.5 mm, while the current T and X series machines are limited to equipment with the thickness not exceeding 9.5 mm..
other
The touchpad is almost a constant part of every generation of Thinkpad. Thinkpad is the most popular laptop for developers of OpenBSD, and T40 is one of the best laptops supported by this system.
