laptop keyboard types incorrect character

[desilva]

I have a laptop with Windows Vista installed on it. Recently the keyboard of this laptop has started to act weird. When I press some of the keys on the keyboard then it will display incorrect character on the monitor as well as in any text document. When I press the below single letters, check what it gives the output:
pressing l give the character 3
pressing j give the character 1
pressing k give the character 2
pressing u give the character 4

What should i do to fix this keyboard problems that are happening in the laptop.

I think that you are using the Hotkey combination in your laptop, which is why when you press any alphabetical keys on your keyboard, then it types or gives our numerical numbers. And you can read from the user manual of laptop incase if you cannot remember the proper combinations that are used for same. Once you find it then it will be automatically restored to the alpha mode and you wont be facing this problem again. If i recollect properly, then you will have to press the combination of the "Fn" key and "Num lock" keys simultaneously, let me know if this solves the issue.
