Taiwan-based PC maker Acer has announced that Gianfranco Lanci, chief executive officer and president of Acer, has resigned from the company, with immediate effect.

The company said that Lanci held different views from a majority of the board members on the company's future development, and could not reach a consensus following several months of dialog. They also reportedly placed different levels of importance on scale, growth, customer value creation, brand position enhancement, and on resource allocation and methods of implementation.

According to reports in local media, the trigger for Lanci's resignation was Acer's unsatisfactory performance in the first quarter of 2011. Prior to this, Acer revealed that its Q1 performance did not reach the expected levels, and it was the second consecutive quarter that it failed to meet its expectation.

By volume, Acer is the largest computer group in Asia. Its core business is providing laptops and netbooks to consumers in Europe and America. Over the last few months, its performance declined and it almost lost its position as the world's second largest PC provider to Dell.

Acer also announced that J.T. Wang, chairman of the company, will take the acting role of CEO in the interim. The company is expected to announce its new global president at the end of April 2011.
