键盘输入异常
一位朋友的键盘出现奇怪的问题：按下特定键时，屏幕上显示的是与该键不同的字符组合。例如，按Z键会显示z`1，按X键则显示x2等。这种现象似乎与按键位置有关，可能是键盘内部线路出现问题。
A friend asked me to have a glance at his keybord.
When I press some keys to his notepad,something funny appears:
WhenZ button is hit, z`1 appears
WhenX button is hit,x2 appears
WhenC button is hit,c3 appears
WhenB button is hit,vb54 appears
When N,M button is hit, mn67 appears
What happened?
Checking : Control Panel>>Regional & Language Options it is OK
since x-2,c-3,vb-45,mn-67 is near in keyboard respectly,Maybe shorted wire in the cable?
I told him to make an entire cleaning of keyboard,but finally,he bought a new one with RMB 15 only,everything is OK then.
