蜂鸣器原主板的故障主要是与Qss和Q54的②、③脚间相连的元件或电路击穿短路或漏电造成。将接于原主板上的电源、内存条和CPU移接到新主板上,通电试机,电源风扇和CPU风扇旋转,蜂鸣器发出清脆的自检声,说明CPU完好。断电测CPU周围的C609~C612、C615~C617的正反向电阻仍然都是5Ω。接好光驱和硬盘的数据线,通电试机,电脑在启动的过程中出现蓝屏,用金海硕大容量硬盘检测修复工具检测硬盘时,弹出“没有发现硬盘”。将硬盘移接到正常工作的惠普电脑上,通电试机,电脑正常启动,硬盘中的所有软件均能快捷准确地执行操作者的指令,将惠普电脑上的好硬盘移接到新换的DELL电脑主板上,通电试机,依然蓝屏,主板是新的,硬盘是好的,只能说明硬盘接口电路或BIOS设置有问题。互换硬盘和光驱接口,能快捷准确地从光盘中读取数据。说明硬盘接口电路完好,只能在BIOS的有关硬盘设置项中寻找解决问题的突破口。共振腔设计得宜,并搭配频率正确的回授式蜂鸣片与正回授电路,将可生成较大音压及正确的频率。AD16-16SML/r23B-TH
