!important;">①开机后是否有蜂呜器“嘀声”，如无，最大可能电源故障，需打开后盖观察电源APDB和SPPD板上对应的指示灯情况，同时测量有无±5V、±12V、3.3V电压来判定故障所在，E版本的PSBC板上每个LED指示灯的红绿状况都代表一种电源是否正常，能很好地判定电源故障情况。</span></p><p style="margin-left: 40px;max-width:

RIP或UAVIO板中右边的小孔内的开关，小孔内的白色LED灯亮。这时再按DVD旁边的ON/Stand-By开关，这时如果能听到嘀的声音，或程序可进一步往下引导，说明FEC或前端（包括前端供电电源）有故障，可作进二步排除查找。</span></p><p style="margin-left: 40px;max-width: 100%;min-height: 1em;color: rgb(51,

!important;">⑤在硬件初始化过程序中死机，始终出不来彩色画面，还有一种可能是HOST母板或UMB上的BIOS出错。这时可以重新设置BIOS后重启，在无法判定的情况下，也可用专用硬盘应用程序中的硬盘初始化软件重启，同时查看是否有三个硬盘正常信息，如有，则硬盘驱动器正常，则下一步考虑重装软件;如见不到三个，则有可能其中坏掉一个，必须更换后再查。同理，硬件初始化过程死机，还有一个办法，断开(取下)UAVIO板，将DVI视频线直接接到在AGP板上，重启后重新设置BIOS配置参数，观察配置每次重启是否有变化，如有变化，很有可能是主板上电池失效。</span></p><p

!important;">⑥当程序引导进人软件初始化过程时死机，首先用硬盘引导程序检查主控计算机硬盘工作是否正常，如果不正常，更换硬盘，并重装软件:重装软件后如能正常运行，则故障排除，如不行，则要怀疑UAVIO和DSC板，或者要更换计算机母板UMB。</span></p><p style="margin-left: 40px;max-width: 100%;min-height:

!important;">机器启动不起来，或2秒后自动关机，可采用如下隔离方法判定：首先隔离前端元件，取下前端电源组件盖板，断开里面两个多芯白色塑料扁平插头和两个旋转连接电缆头，然后在开关2的测试点上连接一个跳线，使PSBC板上保护电路逻辑失效（注意，如重新装回电缆接头时一定要取掉这根线，否则可能损坏电源），重新开启电源，看看是否能稳定，如不能稳定，则尝试隔离后端元件：将前端电源恢复，打开后盖和后端电源盖，在PS-ON和GND之间连接一根跳线，取下SPD板上的5、6、7多芯电缆插头和几传感器插头，重新开启电源断路器，观察电源是否稳定，如能稳定，则建议换UMB联合母板元件；如不能稳定，则隔离SPD板供电的各路元件：首先断开电源，取下SPD板上多个电缆供电连接头中的一个，但前面所提PS-ON跳线仍保留，重新开机查看电源是否能正常工作，如果能够正常，则说明断开插头的那一路元件有短路故障，予以更换即可排除；如果不能正常开机，则将刚才断开的插头插回，再断开另一个插头再开机；如果全部插头都试过，则表明是后台电源本身故障，更换即可排除。</span></p><p
