A friend asked me to have a glance at his keybord.
When I press some keys to his notepad,something funny appears:
When Z button is hit , z`1 appears
When X button is hit , x2 appears
When C button is hit , c3 appears
When B 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.
