SAN JOSE, Calif. (AP) _ For years, Intel Corp.'s microprocessors for laptop computers differed little from those powering desktop PCs. At their core, the chips were designed for machines plugged into the wall, not juiced by a battery.

That changes this month as the world's largest semiconductor company ushers a new technology built from the ground up for mobile computing. The result, Intel says, is high performance and wireless capability with slower battery drain.

The technology, dubbed Centrino, is more than a new processor. It combines the energy-efficient chip, called Pentium M, with components designed to work reliably together and ensure the greatest power savings.

Some laptop vendors are sure to grumble, though, about having to include the entire Centrino package in order to use the brand name and benefit from Intel marketing, said Roger Kay, an analyst for the research firm IDC.

Intel already lets vendors use an ``Intel Inside'' logo. Now, the company will ``certify'' coffee shops, hotels and other wireless hotspots it deems compatible with the Centrino package.

Vendors who opt to mix Centrino's microprocessor with non-Intel components won't get certification and can't use a compatibility logo to advertise their hotspots.

``The last thing in the world you want to do is say `wireless is great' and then have everybody have a bad experience,'' Intel chief executive Craig Barrett said.

He said Intel is ``trying to be very careful with where we say it will work and under what conditions _ and who we work with to bring the new technology into the marketplace.''

Rival chip makers say consumers need not buy the entire Centrino package to get effective technology for WiFi wireless connectivity, which some industry pundits consider the biggest thing in computing since the Internet.

Savvy corporate laptop buyers will likely buy both Centrino systems and hybrids that use Pentium-M along with non-Intel wireless components, said Rich Redelfs, chief executive of wireless chip-maker Atheros Communications.

Analysts say Intel's Centrino blitz could give a big boost to WiFi, which is expanding as cafes, airports, hotels and convenience stores set up ``wireless clouds'' of connectivity to attract customers and add revenue.

Thanks in part to WiFi, portable computing has taken off in recent years. According to researchers at IDC, worldwide unit sales of desktops computers last year fell 1 percent over 2001 while notebook sales increased 9.8 percent.

The Centrino systems, if they live up to Intel's promises, could accelerate that growth.

Because the video display and other parts of the laptop hog power more than the microprocessor, Intel had to design Centrino to be more than the microprocessor, said Anand Chandrasekher, vice president and general manager of Intel's mobile platforms group.

The chip set, which acts a bridge between the processor and the rest of the system, also has been optimized to conserve power, particularly in how much energy is used by the system's display.

On average, Centrino will increase system battery life by an hour over similarly configured non-Centrino computers, Intel says.

In Centrino's debut, the wireless component will support 802.11b wireless connections, with faster 802.11a capabilities expected in future releases. Eventually, Centrino is expected to be able to roam between WiFi and cell phone data networks.

Breaking with Intel tradition, the Pentium M processor will be introduced at a wide range of speeds, from 900 megahertz to 1.6 gigahertz. Intel has not released prices.

``Mobile has always been a derivative of the desktop, but mobile has very different needs,'' said Mark Margevicius, an analyst at the research firm Gartner. ``Pentium M is grown up. It's no longer the forgotten stepchild.''
