Here's a timeline of some key events in Hewlett-Packard Co.'s recent history:
— Sept. 3, 2001: HP announces it is buying fellow computer maker Compaq Computer in a deal that would create a formidable rival to IBM.

HP names Ray Lane, another CEO candidate, non-executive chairman. Lane is a partner at Kleiner, Perkins Caufield & Byers, a renowned venture capital firm.
— Dec. 20: The Securities and Exchange Commission launches investigation into the circumstances of Hurd's forced resignation, which triggered a $9 billion drop in HP's market value. The Wall Street Journal reports the SEC is looking into Hurd's expense reports and his accuser's claim that he told her about the EDS acquisition in advance, among other things.
— Jan. 14, 2011: HP says in a filing in a federal court in San Jose, Calif., that it will investigate the circumstances of Hurd's departure and his severance package, in response to a shareholder's demands.
— Jan. 20: HP shakes up board, replacing four of its members.
— May 3: Leaked memo from Apotheker shows the CEO warning of "another tough quarter" for the company, sending HP's shares sharply lower. The memo says management needs to "watch every penny and minimize all hiring."

— Dec. 9: HP says that instead of selling its webOS mobile system or killing it off, it's making it available as open-source software that anyone can use and modify freely. HP says it still plans to develop and support webOS. In offering it to the open-source community, the company is hoping more mobile apps will be developed under webOS.
— Feb. 22, 2012: Whitman urges investors to be patient and talks of a "multiyear journey" for a turnaround. She says she has a good sense of what the company needs to do, but it will take time to fix HP's internal operations and make investments to grow in areas such as security services, information management and Internet-based systems known as cloud computing.
— March 21: HP says it will combine its PC and printers businesses. The move will save an unspecified amount of money as the company expects improved productivity and efficiency and streamlined customer support and supply chain.
— Wednesday: Estimates from research groups Gartner and IDC suggest that HP has regained much of the PC business it had lost during the period of indecision.
