RALEIGH, N.C. — Lenovo is losing another of its top senior executives.

Ravi Marwaha, president of Asia Pacific and senior vice president for Lenovo Group, is leaving the world’s third largest computer manufacturer to join IBM, according to various reports.

A spokesperson for Lenovo at its headquarters in Raleigh declined comment.

Marwaha is the new General Manager for IBM Global Business Partners. He replaces Donn Atkins, a long-time IBM veteran who has retired, Computer Reseller News reported.

An IBM official responsible for global business partners could not be reached.

Marwaha was one of many IBM executives who joined Lenovo when Lenovo purchased IBM’s personal computing division last year for $1.25 billion. He was IBM’s vice president of worldwide sales for the personal systems group before the Lenovo deal. His first position at Lenovo was as senior vice president for geographies.

Lenovo lost another senior executive this week when Mark Enzweiler, its vice president of global channel strategy and sales, left to join Red Hat. Enzweiler is the new vice president for channel sales at the Raleigh-based Linux software developer and services provider.

Over the summer, Lenovo made several changes in its leadership for Asian operations. Lenovo, now led by William Amelio, recruited several former Dell executives to senior management positions. Amelio is a former Dell executive himself. He also spent 18 years at IBM earlier in his career.

At Lenovo, Marwaha was responsible for sales, marketing, operations, service and support in the Asia Pacific region. He worked at IBM for 36 years, including one stint as general manager for India.

Atkins announced his retirement on Thursday, according to CRN.
