[电脑] Help! 键盘和鼠标死了

lowkey · 发表于 2002-7-2 19:13

不久前，电源突然坏了，买一个新的回来换上，一切正常。关机，固定电源，合上箱盖，拧紧螺丝，再开机就发现键盘鼠标动不了了，再重复以上操作都没用。
开机时系统自检并没有报错，然后已经不可能进BIOS，因为键盘不工作，系统自动企WINDOWS，之后只见鼠标停在屏幕的中心，可是动不了，也没法关机，只能强行关掉电源。莫不是我换电源时碰坏了主板？各位大侠，我该怎么办，快帮帮我。

short the jumper to clear the BIOS

if it doesn't work

boot with keyboard only

if it doesn't work

maybe the I/O chip visited Karl Max.

Eversun, thanks for your answer.
I shorted the jumper, then turn on, system started self-test CPU,clock,RAM, and display an error:
" CMOS checksum bad,
Press F1 to enter BIOS"
but keyboard doesn't work, so it stop there. I also tried taking out the battery for CMOS and put it back, same result. As you said, boot with keyboard only, does it mean without mouse? I tried this also, still same thing.
I don't understand your last suggestion, could you tell me what is "I/O chip visited Karl Marx"? Thanks again.

"CMOS checksum bad"说明CMOS已经复位，这样看也不是CMOS的问题。现在看来问题出在你关闭系统后固定电源的过程中，或者不小心刮伤了部分主板线路，或者由于电源的接触不良导致I/O芯片烧毁或者键盘烧毁，如果拿另一块键盘测试问题依旧的话说明是主板受伤。我想也只有这一个可能。

So, what I can do? Is somewhere to replace I/O chips, or have to buy a new mother board? If buy a new board, anyone has some recommend, considering possible upgrade in future? Thanks.

My PC config is : AMD K6-500 CPU, Micro Star MS5169 Mother board, ATI AGP 8M display card, Motorala 56K modem, and sound card, tower case.

用一个好键盘试试，如果不好用，则是主版坏了。

Surprise! I tried with a good keyboard yesterday, it's working perfect, also my mouse is working. So I get to buy a keyboard now, at least my mother board survived.
Thanks to everyone!
