Dynabook Satellite

The Satellite Pro (also formerly the Satellite) is a line of consumer-oriented laptop computers designed and manufactured by Dynabook Inc. of Japan, which was formerly Toshiba's computer subsidiary. The Satellite Pro is currently positioned between their consumer E series and their business Tecra series of products.

The earliest models in the series, introduced in the early 1990s, were one of the first to directly compete against IBM's ThinkPad line. Models in Toshiba's Satellite family varied greatly—from entry-level models sold to consumers at major retailers to full-fledged business laptops, with the “Pro” suffix, sold through enterprise channels. In 2016, the Satellite line came to an end when Toshiba exited the consumer personal computer market; in 2020, after Sharp Corporation purchased the computer division as Dynabook, the Satellite Pro was relaunched.

The early models did not come with an internal CD-ROM drive, but these soon appeared as mobile technology progressed. Such models can link up with an external CD-ROM drive through the parallel port on the rear (since USB ports came later as well). Some Satellites also lacked an internal floppy disk drive, but a port on the side allowed the use of a proprietary external module for such. These machines tended to be smaller in physical size than their contemporaries.

A Toshiba Satellite personal computer was used to send the first email ever sent by a sitting U.S. president in the course of their duties. The email was sent by president Bill Clinton using the personal computer of the White House Medical Unit emergency physician Robert G. Darling in response to an email by the astronaut John Glenn as he was aboard the Space Shuttle Discovery.

Notable models included the Satellite 5005-S507, which was the first to ship with NVIDIA GeForce 4 440 Go GPU and cost $1,999. The Satellite 5105-S607 was the first laptop with cPad technology and cost $2,499. The Satellite 5205-S703 was the first laptop with built-in DVD-R/RW drive and cost $2,699.

Sharp Corporation obtained 80.1% of Toshiba's computer subsidiary in October 2018. In April 2019, Sharp renamed the subsidiary Dynabook Inc. In 2020, Toshiba sold their remaining shares to Sharp. Sharp resurrected the Satellite Pro series that year.

The Satellite line was introduced in 1992 with the T1800 and T1850 models, the T1850C variant of which was one of the first notebooks with passive-matrix color liquid-crystal displays (LCDs). Succeeding entries in the line followed this naming scheme, such as the Satellite T1900, T2110CS and T2130CS. Beginning with the barebones 100CS and 100CT in February 1996, Toshiba began using only numbers to name their Satellites, a convention which continued until 2003 with the introduction of the Satellite A series.

Toshiba began using letter prefixes to differentiate its concurrent series of Satellite laptops. These included the A series; the C series; the E series; the L series; the M series; the P series; the R series; the S series; the T series; the U series; and the W series. CNET wrote in 2011 that "Toshiba may not run out of new product lines until it runs out of letters".
