How to change the keyboard the settings for laptop ar?
Cause the lenovo one that i bought, 1 key got 3 functions. Den for example when click the letter o, a number will come out instead of the letter. Den must click function before i can get the letter.
I have been looking around the manual but it did not give any clues. Anyone knows how to configure this thing?

Look at the LED lights. See if anything of the LED lights are lighted up. Make sure you see carefully. Some LED lights are for the hard disk and will be blinking.

Most likely it's Num Lock or Pad Lock that is lighted up. Just press the Fn key + the Num Lock or Pad Lock to turn it off.

The Num Lock or Pad Lock key is printed on the keyboard itself, lettering colour is same as the Fn Key.
