The One Laptop Per Child (OLPC) group said Thursday that it had raised the price for its hundred-dollar laptop to US$175, but was still confident it would collect enough orders to begin volume production by September.

OLPC now has orders for 2.5 million units, but needs to reach 3 million units by May 30 in order to give its suppliers enough lead time to fill the pipeline with parts, said OLPC founder Nicholas Negroponte in a meeting with analysts in Cambridge, Mass., on Thursday.

"We are at the most critical stage of OLPC's life," he said. "A year and a half ago, we were selling a dream, but it's easy to sell dreams if you're passionate and can share that passion with other people. But that was dreams, and now we've got to launch. We need 3 million units to trigger the supply chain."

The goal of the OLPC project is to create a durable, power-efficient notebook PC that is cheap enough for developing nations to use as a common classroom tool.

OLPC has distributed about 200 beta versions of its XO laptop to each of the seven countries that has committed to making bulk orders so far: Brazil, Argentina, Uruguay, Nigeria, Libya, Pakistan and Thailand. The group has also sent nearly 2,000 laptops to software developers around the world.

Negroponte did not say where the remaining orders could come from, but did say that Peru and Russia may join the group. He also said he had fielded inquiries from the governors of 19 U.S. states including Florida and Massachusetts, a demand that has softened his previous resistance to selling the PCs in U.S. markets from "never" to "maybe."

If the group meets its sales goal, it will quickly boost production, reaching levels of 400,000 per month almost immediately after the Sept. 20 launch date. Manufacturer Quanta Computer of Taiwan would produce 1 million laptops by the end of 2007, and 3 million within nine months of the launch, said Mary Lou Jepsen, chief technology officer of OLPC.

Once they reach that volume production, the price will soon begin to fall again, since OLPC is a nonprofit organization and has recently struck a deal with Citigroup's Citibank to handle the administrative side of the business, Negroponte said.

"The manufacturing cost of these laptops is $175. We'll charge maybe $176 to cover the cost of these offices. Usually 50 percent of the cost of a laptop is sales and marketing, distribution and profit, but we don't have any of those things," he said. He also pledged that OLPC would readjust the price every business quarter, leading it to drop about 25 percent within a year.
