Most notebook ODMs will ramp up the production of ultrabooks for their branded PC vendors in the fourth quarter, with Quanta Computer to begin volume production of HP's ultrabook models in November, according to industry sources.

An array of Sandy Bridge-based ultrabooks will hit the market during the 2011 year-end holiday season, while more Ivy Bridge-based models will be rolled out in the first half of 2012, said Intel vice president Mooly Eden.

Acer led all PC vendors and has begun delivering its Aspire S3 ultrabooks, manufactured by Wistron, to its distributors, the sources revealed.

While Asustek is planning to unveil its ultrabook models in early October, the company will start shipping devices to distributors at the end of September, said sources, adding that Asustek's ultrabook shipments will top 100,000 units in September and ramp up higher in October and beyond. Asustek is outsourcing its ultrabooks to Pegatron Technology.

Toshiba will outsource the production of its Portege Z830 ultrabook lineup to Compal Electronics and Quanta Computer, using Intel's second-generation Core i3, i5 or i7 processors, the sources indicated.
