I upgraded laptop's (NEC Versa E6300) OS into Windows 7. At the beginning there was no problem, but after about 1 month of using it, i got strange problem with the keyboard. Some characters (m j k l ; u i o p 0) don't type as they are supposed to type, i.e. it these char instead: (0 1 2 3 - 4 5 6 * /). I tried to change country setting and also suggestion in some forum but no luck. Btw I am writing using on screen keyboard now!! Here is what happen if I type the tittle using the normal keyboard: 2eyb6ard d6esn't ty*e c6rrect3y Any suggestion is really appreciated.
