    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。而其蜂鸣片须与共振腔频率搭配，才会有较高的音压输出，并由外部振荡电路生成推动信号，使蜂鸣器发出声音。
