第6题:

计算机使用一年多了,但最近计算机时钟总比较慢,怀疑是CMOS电池的问题,就换了一块新电池,结果不到一个月电池电量就用尽了,BIOS参数全部丢失。而且每次开机自检时都会显示“CMOS checksum error-----Defaults loades”,此时必须在BIOS中选择Load BIOS default选项才能正常启动,请问这是什么原因?该如何处理?


正确答案: 从所述现象来看,很可能是因为主板上的纽扣电池没电了,建议换一颗相同型号的新电池。另外,现在大多数主板上有CMOS CLEAR跳线,如果跳线错误,将使CMOS电池处于短路状态,很快即可消耗完CMOS电池的电能,注意检查这根跳线。如果换电池后故障依然存在,则可能是主板出现了故障,如CMOS电池插座、CMOS供电电路滤波电容、CMOS芯片有短路或漏电现象,如果主板出现了这类故障就只能送到专业维修店去修理了。
