There was also 18 per cent decline, year-on-year, in mobile PC shipments in the second quarter due to a deeper slack in consumer demand.
"In the absence of any substantial demand from enterprises this quarter, the Indian PC market performed dismally, re-emphasising the fact that sentiments were not very positive in the second quarter of 2015," Gartner Research Director Vishal Tripathi said.
The enterprise segment might witness some growth going forward due to government and education projects but there might not be a significant bounce back, he added.
White boxes (including parallel imports), which accounted for 44 per cent of the overall desktop market, declined 7 per cent in the second quarter of 2015 compared to the same period last year.
HP maintained the numero uno position with 26.3 per cent market share, followed by Dell (21.6 per cent), Lenovo (18.1 per cent) and Acer (9.6 per cent) in the said quarter.
