Presario V2000 Keyboard Problem

HP Compaq Presario V2000 Laptop Keyboard problem solver.
Just now, i have repaired a Laptop, This is Compaq Presario V2000. The problem is some button of keyboard can't working. The button that not working are 'Enter', '\', 'Backspace', 'Up button', 'Down button' and some complement button. To solving this problem i have disassemble the keyboard, i release all button 1 by 1 because the button not working on the right but the base and the end of layer of keyboard on the left. You know the keyboard is consist of 3 layers, and to solving this error you must disassemble the bottom layer, the line from motherboard socket to the enter button etc. is in the bottom layer.
And after i disassemble the bottom layer i check line connection from the nearest point of 'enter' to the nearest point of keyboard socket. And i found that the connection is cut off, and i must connect it.
The connection cut off by overheating of laptop interior. the point of the cut off line is a like scorched.
And then, i connect the cut off line by the cable. I take one of small stranded cable content. This cable will connecting between 'enter' button and keyboard socket.
To put the cable you can use a double tape or adhesive isolator. I have done this steps and success.
I hope this can be help you all
