The ThinkCentre is a line of business-oriented desktop computers designed, developed and marketed by Lenovo, and formerly by IBM from 2003 to 2005. ThinkCentre computers typically include mid-range to high-end processors, options for discrete graphics cards, and multi-monitor support.[1]



IBM ThinkCentre used as a Linux server

The ThinkCentre line of desktop computers was introduced by IBM in 2003. The first three models in this line were the S50, the M50, and A50p.[2] All three desktops were equipped with Intel Pentium 4 processors.[2] The chassis was made of steel and designed for easy component access without the use of tools.[2] The hard disk was fixed in place by a 'caddy' without the use of screws.[2] The caddy had rubber bumpers to reduce vibration and operational noise.[2]

Additional updates to the desktops included greater use of ThinkVantage technologies.[2] All desktop models were made available with ImageUltra.[2] The three desktop models also included an 'Access IBM' button, allowing access to onboard resources, diagnostic tools, automated software, and links to online updates and services.[2] Select models featured IBM's Embedded Security Subsystem, with an integrated security chip and IBM Client Security Software.[2]

Acquisition by Lenovo[edit]

In 2005, after completing its acquisition of IBM's personal computing business, leading to the IBM/Lenovo partnership, IBM/Lenovo announced the ThinkCentre E Series desktops, designed specifically for small businesses.[3] The ThinkCentre E50 was made available in tower and small form factor, with a silver and black design.[3]

In 2005, Technology Business Research (TBR) observed an increase in the customer satisfaction rate for ThinkCentre desktops.[4] According to TBR's "Corporate IT Buying Behavior and Customer Satisfaction Study” published in the second quarter of 2005, Lenovo was the only one of four surveyed companies that displayed a substantial increase in ratings.[4]

In May 2005, the ThinkCentre M52 and A52 desktops were announced by Lenovo.[5] These desktops marked the first time the ThinkCentre line incorporated dual-core processors and 64-bit technology.[5] At the time of release, Lenovo also announced plans to incorporate Intel Active Management Technology in future products.[5]
