Keyboard non-stop "enter"

bctam

My Laptop is HP V6-1254TX. Some of keys have problem such as "q", "w", "e", "r", "u", "i", ......
When I click relevant key, it can show but will be non-stop "enter" until click other no problem key then stop.
I use external USB Keyboard is fine.
I don't know the problem come from keyboard or mainboard.
Please help to get me advice or solution.
I have one more question about laptop keyboard. Is it have any electic equipments such is IC or resistor or  capacitor?
Thanks,

keyboard has IC to identify which key is pressed by user
and then sent key to mainboard.

I guess,keyboard failed probability > mainboard failure

If you using external keyboard is fine it means you PC main board and system working properly.

Try to get a replacement laptop keyboard replace it. You may easily to find and learn how to replace you keyboard  from video in youtube. Good luck.

There is no IC inside the laptop keyboard. There are only dry contact switchs layout with FPC (film printed circuit) inside the laptop keyboard.
