Some keyboard keys stopped working

[dwmn6]

A few weeks ago, My computer keys stopped working automatically while playing a game, after the other day when I spilled something in my keyboard.

It just happened randomly, not on the same day I spilled something in my keyboard.

I reinstalled drivers and even reinstalled Windows, nothing worked.

Please help, i dont know what to do.

Hi,

Most likely you are going to need to replace the keyboard. It is not a very difficult or expensive fix. A couple of questions first. 

If you look on page 38 of service manual you can see the different keyboards and the steps to replace. For example, the US keyboard has part number 776778-001 and if we search with part number online it can be found quite easily. The steps to replace the keyboard are on the pages 38-40.

Can you fix the cable if the traces are burned? I believe that is the problem.

It is very difficult to fix flex cables and in this situation if the traces are burnt it could be because there is a short somewhere else in the keyboard and heat burnt the cable in its weakest part. I personaly would replace the keyboard which you can probably find online for about 15$, since using the defective keyboard, even if somehow "fixed", might present further problems in  the future.

There are 3 different types of keyboards for your model:

For use in Canada    part number 776778-DB1

For use in Latin America   part number 776778-161

For use in the United States   part number 776778-001

If you search online with part number, I believe you have the US keyboard with part number  776778-001 you can find them.

So searching with 776778-001 we get (I do not know what country you are in:

Hope it helps,

Hi,

You can try to remove, clean the keyboard and reinstall  it back to the laptop. If still doesn't work, try using an external keyboard just to isolate the issue. If external keyboard works properly, then you will have to replace the keyboard on your laptop. You can buy HP replacement keyboards from https://www.laptopkeyboard.com/
