Lenovo suffers from lack of brand awareness outside Asia

Despite strength on its home turf -- Lenovo commands a third of the Chinese PC market, the world's largest after the United States -- the firm is struggling to expand beyond Asia.

It continues to relinquish market share in major international markets due to a lack of brand recognition and consumer exposure, experts say.

Chairman Yang Yuanqing told Reuters in September it would take at least three years to return to strong profitability as competition intensifies and corporate demand lags.

"Our key concern is the loss-making America business. I do not expect it to turn around until the second half of next year, when the corporate PC replacement cycle starts," said an analyst at Cazenove.
