One of the ideas seems to be to come up with a standard motherboard for the 11" and 13" notebook form factors, as well as a standard one for 15" and 17" models:
The interest is reflected on their RFQs (requests for quotation) to notebook ODMs for models to be launched in 2016, the sources said. The motivation of using more common components aims to cope with rising labor costs in China and increasing price competition arising from shrinking global notebook demand, the sources indicated.
For motherboards in particular, vendors are inclined to adopt the same motherboard for 11-inch and 13-inch notebooks and for 15- and 17-inch models, the sources said. In the past, it was quite difficult to use the same motherboard for 11- and 13-inch notebooks due to differences in processors, the sources noted. However, vendors are likely to adopt processors of the same or comparable specifications for 11- and 13-inch notebooks to be launched in 2016, the sources indicated.
