Dell founder Michael Dell will relinquish his chief executive officer title to president and chief operating officer Kevin Rollins. Dell will remain chairman of the company's board of directors.
The move will be effective from 16 July, the date of the company's shareholder meeting.
Dell will still be "deeply involved" in the day-to-day business of the company he founded as a college student in 1984.
Rollins and Dell have shared power at the company for several years in an unusual arrangement for a company of Dell's size. Rollins joined the company in 1996 as president of Dell Americas after leaving consultancy Bain & Co.
Dell focuses on technology trends and research and development, while Rollins heads the company's operations and future strategies.
Shareholders will also consider Rollins' appointment to Dell's board at the July meeting. Rollins would replace existing board member Mort Topfer, a former Dell executive who decided not to stand for re-election.
