Lenovo's quarterly revenue rose 3 percent to $10.7 billion, below analyst expectations, as the world's No. 1 P.C. maker pointed to "severe challenges" in selling smartphones in China and PCs and tablets around the world.
The company said that about 3,200 people in non-manufacturing positions would also lose their jobs to save $650 million in the second half of 2015.
The revenue result compared with expectations of $11.29 billion, according to analysts polled by Thomson Reuters SmartEstimates.
The Beijing-based company's net profit plummeted 51 percent year-on-year to $105 million, but was ahead of a 59 percent drop expected by analysts.
