Problems with my Laptop Keyboard

[anil8876]

My spacebar, backspace, backslash and enter buttons on the laptop keyboard do not work, all others work fine, how can I solve this problem

you could have a loose cable internally. or there was a spill on the keyboard. If the keyboard cannot be fixed it will have to be replaced. If you are a novice, I suggest professional help.
