Fiorina was frequently at odds with HP's board of directors, and she had to fight with the board for the merger. Walter Hewlett (the son of company co-founder William Hewlett) was a source of particularly strong opposition. Hewlett originally voted with the other board members to approve the Compaq deal, but he later changed his mind. He launched a proxy fight against Fiorina's efforts which Fiorina won with a "razor-thin margin" of 51.4% of the shareholders, with the institutional shareholders providing the bulk of the support. Fiorina was supported in the proxy battle by other board members, including Richard Hackborn, Philip M. Condit, George A. Keyworth, II, and Robert Knowling. Fiorina proceeded to reorganize HP and merge the parts of it that she kept with Compaq.
