In 2013, Dell Chairman and CEO Michael Dell secured shareholder approval for his $25 billion offer to buy and take the firm private after a drawn-out battle. The company was once at the top of the PC business, boosted by its pioneering model of allowing customers to order custom-configured PCs online, while working closely with suppliers to keep costs low.

Dell has around 14 percent of global PC market share, ranking third globally in the second quarter of 2015, after HP and Lenovo, according to data from Gartner. But globally, PC sales are still falling, with only around 251 million desktop and laptop units, or around $151 billion worth, expected to be sold this year, down from around 343 million, or around $218 billion, in 2012, Gartner said. Around 31.9 million units, or around $18.2 billion worth, are expected to be sold across emerging and mature Asia and greater China this year, the data show.
