Lenovo, the world's second-largest maker of PCs, has reported a 54% rise in profits on overseas acquisitions and a jump in sales.
Net profit rose to $153m (£96.8m) in the three months ending 31 December.
Lenovo said it saw strong sales in the US and emerging markets, which allowed it to buck the trend in a declining global PC market.
Last year, it overtook Dell to rank second behind Hewlett Packard in global PC sales.
Beijing-based Lenovo has seen strong growth in recent years due to expanding sales in China, as well as acquisitions in markets such as Germany and Japan.
The company warned of hurdles to come in the coming months.
"Although challenges to worldwide PC demand remain, such as the pace of global economic recovery and the on-going debt crisis in Western Europe, and even a hard disk drive supply shortage and cost increase, Lenovo remains optimistic that its growth momentum will continue," it said in a statement.
