It added that weak sell-in for much of Q2 amid ongoing consumer distractions, such as phones and tablets, as well as a slowing economy affected the PC market performance in China.

While consumer sentiment in the rest of region was also tepid, a higher-than-expected shipment for a large education notebook project in India helped to offset some of this decline, it said.

Another research firm Gartner attributed the decline in sales in the second quarter to overall weakness across the region.

In Asia/Pacific, PC shipments surpassed 26.8 million units in the second quarter of 2013, an 11.5 per cent decline from the first quarter of 2012, it said.

All country markets across the region showed weakness, but India performed slightly better due to a state PC tender fulfillment, it added.

"China's PC shipment remained weak as the consumer market was hampered with lack of new demand generation programmes, such as subsidized PC programme in the rural cities," Gartner said.
