HONG KONG, May 23 (Reuters) - China's Lenovo Group reported on Thursday a rise of 9% in fourth-quarter revenue to $13.8 billion, as the world's largest maker of personal computers (PCs) exits a demand slump following the aftermath of the COVID-19 pandemic.

Revenue for the January-March quarter beat an average estimate of $13 billion drawn from eight analysts according to LSEG data. (Reporting by Josh Ye; Editing by Clarence Fernandez)
