Hewlett-Packard unveiled a new desktop computer, just days after the technology company disclosed plans to sell or spin off its personal-computer business, according to The Wall Street Journal.

Shares of the world's largest personal-computer maker were up 2% at $24.07 in recent premarket trading after falling 20% last week.

HP said the latest all-in-one Elite business model can deliver up to 15% faster hard-drive access, 40% better performance and less downtime as a result of remote information-technology management capacity. The computer, which is energy-efficient, also is equipped for remote face-to-face communications and online conference center capabilities.

HP's announcement that it plans to get out of the PC business was an about-face that highlights how growth has pivoted from the computers that so long ruled the industry toward software and mobile devices, where HP has largely failed to compete.

At the same time, HP agreed to buy UK software firm Autonomy Corp. for about $10 billion, seeking to move further into the higher-profit business of analyzing data for corporations.
