The third quarter always used to be buoyant for PC sales until sales started to slow a few years ago as smartphones and tablets came into their ascendancy.
Taiwanese wire Digitimes reports that ODMs (original design manufacturers) largely based on the island has fallen quite short of expectations.
It attributes the growth in the second quarter not to a rise in interest in the platforms any more, but because Windows XP was phased out in the spring.
People realised that if they were going to buy a notebook, it would be as well to do it then and move to a new Windows operating system.
Reports earlier this week suggested that sales of tablets in North American and western European markets had reached a degree of stasis too. Most people who wanted a tablet have got one.
