Last year saw the biggest ever decline in PC sales, according to a report by Gartner.
Shipments in the last quarter fell for the seventh quarter in a row, down 6.9 percent year-on-year to 82.6 million units. Overall shipments for the year were down 10 percent to 316 million units - the first-ever double-digit drop.
In Asia-Pacific, Q4 volumes fell 9.8 percent compared with Q4 2012.
None of the top three vendors – Lenovo, HP and Dell – would comment on the Australian performance when contacted by CRN; according to Gartner, country-level data will be released in four to six weeks.
The only PC maker to see growth throughout 2013 was Lenovo, which remained the biggest manufacturer with 17% of the market, according to Gartner. The company's shipments grew nearly 7 percent in the final quarter to 15 million units.
According to Gartner, it marks a milestone in Lenovo's battle with HP for dominance of the market.
"HP and Lenovo have been virtually neck and neck for the top global position in the PC market throughout 2013. Lenovo took the lead in the fourth quarter, as it did last quarter, accounting for 18.1 percent of global PC shipments."
Lenovo chief executive Yang Yuanqing said: "Lenovo is proud that we have become the clear global leader in PCs; we are grateful to our customers for their continued support; and we are extremely optimistic about the future of the $200 billion-plus PC industry."
HP held onto second place, despite seeing a drop in the final quarter to 13.5 million units.
Dell managed growth in the final quarter, with shipments rising 6% year-on-year to around 10 million units - though overall shipments for the year stayed flat.
The biggest losers of the quarter were Asus and Acer; Acer's shipments dropped a painful 16% year on year to 6 million units, while Asus' fell 19% to 5 million.
Analysts attributed the fall to the growing preference for tablets and smartphones - but, on a rare note of optimism, said the worst was probably over.
"Although PC shipments continued to decline in the worldwide market in the fourth quarter, we increasingly believe markets such as the US have bottomed out, as the adjustment to the installed base slows," said Gartner analyst Mikako Kitagawa.
