My Acer TravelMate 4672WLMi laptop keyboard diplays the @ key when shift inverted comma is pressed and the reverse with the @ key. The backslash key produces the # key. Any suggestions James South Africa

Change the Key sequence form Regional & language setting from control panel key boards and language the change key board.
this will solve your problem

I think you may have the wrong keyboard template loaded?
To my knowledge there could be only 2 reason for this prob, either the keyboard layout might have changed or because of some virus.
do the following to check whether the input keyboard layout is correct.

Control Panel--> Regional and Language options--> Languages tan--> Details--> make sure you have only US in the installed services and not United states- Dvorak, or some other wrong one,
if you have any click on US and click on apply everything should be fine.

Hi James

Your keyboard settings seems to have gone a bit funny

Please try the following

1) Click Start>Control Panel>Regional and Language Options
2) Under the tab Regional Options ensure that the standards and Location are correct
3) Click on the Languages tab and then click on details and ensure the language is correct
4) Click Apply and then OK

This will resolve the issue for you
