I have a problem with my Toshiba satellite L10-108 laptop keyboard. If think that I might have changed my keyboard settings somehow. My keys are all mixed up. If I for example press the key j in 1 is now pressed. Somehow some of my keys on my keyboard changed. I have no idea how to change it to its original setting.
It sounds like you have turned on the "NumLock" feature that many laptops have.( j=1 k=2 l=3 u=4 i=5 o=6 m=0) It's intended for use by people who need to enter large amounts of numeric data.
Find the NumLock key and press it to reverse things and set it back to normal. On my Dell it's Fn + F4, on my Compaq it's Fn + ScrLock. It's different on every make and model. But, it's somewhere on the keyboard .
