Acer president and CEO Gianfranco Lanci has parted company with the Taiwanese company after clashing with board members because of "different views".

Acer's statement, which says that Acer Chairman J.T. Wang will take charge for an interim period, indicates that Acer wants to shifts its focus back to PCs whilst treading carefully in the emerging mobile and tablet markets.

"The personal computer remains the core of our business," said Wang. "We have built up a strong foundation and will continue to expand within, especially in the commercial PC segment.

"In addition, we are stepping into the new mobile device market, where we will invest cautiously and aim to become one of the leading players.

"In this new ICT industry Acer needs a period of time for adjustment. With the spirit of entrepreneurship, we will face new challenges and look to the future with confidence."

The move comes as the Financial Times reports that Acer's share price had plummeted 25 per cent since 28 December.
