Following the upcoming release of desktop Skylake processors at Gamescom in Germany in August, Intel's Skylake processors for notebooks will start showing up in October. The CPU giant is planning to launch a total of 18 notebook Skylake processors in the fourth quarter, looking to help boost notebook demand. However, because many notebook brand vendors are still suffering from inventory issues, they are continuing to adjust their schedules for Skylake products to minimize the impact.

The sources pointed out that many notebook brand vendors saw their inventories building up quickly during the first half because their sales in Europe were stagnated and emerging markets such as China were performing weaker than expected. These vendors are seeing their notebook inventories digesting in a rather slow pace, which is affecting their plans for new products and orders.

Intel is set to release its K series processors and Z170 chipsets for desktops initially at Gamescom and will release eight more mid-range and high-end processors later.

The notebook supply chain has already prepared to start mass-producing Skylake-based notebooks in September and Hewlett-Packard (HP) is currently ahead of others in the preparation, while most of the rest are still busy trying to clear up their inventories.

As for Windows 10, the sources are skeptical about the operating system's ability to give a major boost to notebook demand and the third quarter is unlikely to see a usual seasonal uptick in demand. These vendors are expected to see some recovery in the fourth quarter after clearing their inventory.

Several notebook brand vendors also plan to release Skylake-based Chromebooks in October and will not release the entry-level Celeron-based models until the first quarter of 2016.
