That’s according to Digitimes Research, which said HP saw its shipments fall by 45 percent and Lenovo fall by 30 percent compared to the previous month.

Microsoft has been forced by incursions from Chromebooks to slash its licensing rate – but these machines are not immune to a more general decline in notebooks.
The news may be bad for HP and Lenovo but could be good news for people looking for notebook bargains – most of the machines sitting in warehouses are aimed at home use.
It’s still not entirely clear how Microsoft will approach the thorny matter of Windows 10 when that’s launched in the third or fourth quarter of this year. It also hasn’t disclosed how many different varieties of Windows 10 it will offer at launch.
There is some sentiment that people are holding off buying notebooks until they have a clearer picture of what is going to emerge from Redmond.
