Xiaomi Technology is expected to delay the launch of its first notebook to the second quarter of 2016, one quarter behind its original schedule, according to sources from Taiwan-based supply chain makers.

Xiaomi's first notebook will begin volume production in May and hit the market in June at the earliest, indicated the sources, noting that the delay will allow more time for Xiaomi to establish retail and after-sales service channels.

While Xiaomi is to hold a product event on March 29, the vendor is unlikely to officially unveil the notebook, said the sources.

In fact, Xiaomi is still fine-tuning its strategy for the notebook business and will launch only one model initially, instead of two models as originally planned, revealed the sources.

Xiaomi's first notebook is expected to come with a 12.5-inch display and run Windows 10. Initial shipments are likely to reach 400,000-1 million units, the sources estimated.
