On Thursday (May 27) China's Lenovo Group posted a rise in fourth-quarter profit of 512 percent.

Consumers working and studying from home powered demand for the world's biggest maker of personal computers.

Profit for the quarter ending March 31st jumped to $260 million, beating forecasts.

While revenue rose 48% to $15.6 billion, from almost $10.6 billion a year earlier.

The global health crisis fuelled the buying of laptops, televisions and personal gadgets.

That's propped up sales of various electronic companies including rival Samsung.

Lenovo said it's strengthened its lead in PCs with a quarter share of the market, ahead of HP and Dell.

Research firm Gartner says worldwide shipments of personal computers jumped by a third in the March quarter - the fastest growth it's ever recorded.
