Thomas J. Perkins has resigned from the board of directors at Hewlett-Packard (HPQ) - Get Report, the company announced late Friday.

HP offered no explanation for the resignation, which leaves the company¿s board with 10 members.

Perkins is a founder of venture capital firm Kleiner Perkins Caufield & Byers and a former HP executive. He retired from HP's board in 2004 but returned early last year as the board was struggling with then-CEO Carly Fiorina, who was soon fired.

¿Since he first joined the company nearly 50 years ago, going on to serve as leader of HP's early computer operations, an executive at HP Labs and ultimately as a director, we have benefited from Tom's business insights and understanding of technology,¿ said Mark Hurd, HP¿s CEO, in a news release. ¿He has been instrumental in championing improvements that are leading to a stronger HP.¿

The company¿s shares ended Friday down 46 cents at $32.02.
