Updated at 3.30pm, Friday: Legend Holdings, the mainland's largest computer maker, is being accused of hiding problems with its 'Zhuri' series commercial PCs, the People's Daily reported on Friday. Hengli Computer Engineering in Hangzhou told a Beijing court that it tested extension boards in three Zhuri computers and identified weak signals. The boards enable the computers to be compatible with other systems, the People's Daily said. The computers, bought in August, either cannot be properly turned on, or stop working because of 'weak' signals, representatives of the Hangzhou-based plaintiff told the court. Hengli Computers also claimed the problems were widespread across the PC series. It demanded Legend recall the computers and pay compensation. It also urged Legend to tell the public about them, the paper said. A man, calling himself Mr Wen from the Legend's legal department, told the People's Daily the signals were weak - but not enough to cause major errors. After the court hearing, Legend agreed to recall the three computers and compensate Hengli. But it said there were not widespread problems with the computers and refused to make a public announcement. Legend said in a statement it could not trust test results by Hengli because the tests were not done according to industry standards. Hengli said it would seek tests by authorised testing agencies and present results at the next court hearing. No date has been set for the hearing.
