NEW YORK - Microsoft is introducing new Surface tablet computers and accessories, including a professional model that allows people to use it more like a laptop or a desktop.
The Redmond, Wash. company is trying to boost its tablet business as sales of traditional desktop and laptop computers decline.
The Surface Pro 2, unveiled at an event in New York, is targeted at professionals who want the full power of a laptop in a tablet-style device. The kickstand built into the device is redesigned to make it easier to use on laps. In the past, it worked best on a flat surface such as a table.
Microsoft says the Pro 2 also offers a 75 percent improvement in battery life over the previous model. There's also a new cover accessory that extends battery life even further. An optional docking station allows the Pro 2 to be used like a laptop.
A cheaper model, Surface 2, offers a better screen and other improvements over last year's Surface RT.
The Surface Pro 2 will start at $899 and the Surface 2 will start at $449.
The announcement comes about a month before Microsoft releases an update to its Windows 8 operating system on Oct. 17. Among other things, Windows 8.1 will be usable on smaller touch screens, which have become popular because they are cheaper and easier to carry. The previous version of Windows 8 was limited to tablets with 10-inch to 12-inch screens.
Microsoft began selling Surface tablets last October, but sales have been slow. The company shipped about a million tablets in the first three months of 2013, according to research firm IDC. That includes about 260,000 of the slimmed-down RT version of Surface and 750,000 of the Pro version, which is compatible with older Windows programs. The shipments gave Microsoft a meager 2 percent share of the tablet market in the first quarter. By the second quarter, Microsoft tablets dropped out of IDC's Top 5.
Microsoft, which is based in Redmond, Wash., absorbed a $900 million charge in the April-June period to account for its expected losses from the Surface RT after it slashed prices to stimulate demand. The $150 cut brought the price of the Surface RT with 32 gigabytes of memory to $349. The Surface has a 10.1-inch screen measured diagonally. The RT version is 1.5 pounds. The Pro version is 2 pounds and starts at $799, $100 less than it was at launch.
Microsoft has manufactured devices before, such as its Xbox gaming console. In selling the Surface, the company became a competitor to its many manufacturing partners, which rely on its Windows operating system to power their machines. Microsoft is trying hard to succeed in tablets because personal computer sales are falling.
