Launched in April 2005, the ThinkPad T43 and T43p laptops were the last T-series laptops manufactured for IBM. The 15-inch T42 and T42p models were offered with an optional 1400 × 1050 or 1600 × 1200 "FlexView" IPS LCD display.
The design was followed by the T41 and T41p and the T42 and T42p (ATI Mobility 7500, 9600, and FireGL T2), with almost complete parts interchangeability, except for the fan (normal or p-series), keyboard (14.1" or 15"), screen (14.1" or 15"), and screen inverter. The ThinkPad T40p offered ATI Mobility 9000 with 64 MiB VRAM, a 14.1-inch LCD display with 1400 × 1050 resolution, a maximum of 2 GiB PC2100 RAM, and a 60 GB IDE hard disk. The last ThinkPad to have been manufactured directly by IBM (T43).Īnnounced in March 2003, the ThinkPad T40p represented the first in the T series' "performance" class of laptops. This was complemented by a 60 GB hard drive and a DVD-ROM/CD-RW combo drive, making it a powerful laptop. Additional options included the ATI Mobility Radeon 7500 video controller with 16 MiB graphics memory, a 14.1-inch LCD display with a resolution of 1400 × 1050, and 1 GiB PC2100 RAM. The ThinkPad T30 was released in May 2002, with options for the Intel Mobile Pentium 4-M processor with the Intel 845MP Mobile Chipset. įurther minor refinements were made to the T2X series resulting in the T22 and finally in 2002 with the T23 a Pentium III-M 1.13 GHz "Tualatin" having 128 MiB of RAM and a 30 GB hard drive. The hard disk space offered was a 32 GB-high for the time. The 14.1-inch LCD display offered a higher resolution of 1400 × 1050. In October 2000, the ThinkPad T20 was upgraded and released as the ThinkPad T21 laptop with the Intel Mobile Pentium III (800 MHz) CPU. With the addition of an internal 8x DVD-ROM drive, the weight remained as low as 2.4 kg (5.2 lb).
With a weight of 2.1 kg (4.6 lb), the T20 was the lightest laptop offering with a screen size of 14.1-inch (360 mm). The ThinkPad T20 was released by IBM as the 14.1-inch successor to the 13.3-inch ThinkPad 600 laptops.
Users were also given options to swap components for mobility, like a DVD player, writeable CD drive or numeric keypads. Despite a 14.1-inch screen, similar to desktops at the time, the titanium composite body on the laptop was designed to keep the weight as low as possible.
įrom the time of its inception, the series was designed to balance speed and mobility. This resulted in the development of the IBM Embedded Security Subsystem. The laptop was meant to cater to users working with multiple networks and in different environments. IBM introduced the T series as part of their ThinkPad brand in 2000. Originally developed by IBM, and introduced in 2000, the brand was sold along with the rest of IBM's consumer computer division to Chinese technology company Lenovo in 2005, who have continued to produce and market succeeding models. The ThinkPad T series is a line of laptop computers.
