    Yes! I mean those. Double check them. Everything else seems to be ok.

      Got an account on annual account Vinafix but i'm not able to open the .bin document (which tool can i use to open it properly)? Also the .Fz document, tried to open on a Mac with Fritzing tool but nothing appears in the application :s

        Openboardview can open .fz files with some key that you have to optain via some IRC Channel but i never bothered doing that. Not really sure how that works to be honest. Maybe a little bit of googling may help. Can you attach the files?

              Pin 31: GND
              Pin 32: GND

              Confirm those connections and measure directly from connector to ec and append your values to the list. Pin 25 - 32 Should be ok anyways. Pin 1 - 24 are important.
              Pin 1 is marked on your board. Theres a small flipped 1 beneath the first pin.

                Many thanks for your inputs.

                Pin 1 to 26 have indeed continuity with ENE ic. Only pins 27 and 30 doesn't have continuity with ENE ic (and they also give different values than all others pins in diode mode).
                Also as i don't have ENE IC schematics, i don't know which pin is which number in your list :s
                Also what do you mean exactly by appending the values? You mean measuring voltages?

                  Re: Asus UX510U issue with 8 keys on the Keyboard

                  to open .fz use boardviewer.net
                  I use openboardview with key but you should
                  know how rebuild it....
                  there are some signs of water
                  spillage on the board ?

                    How can you convert a .fz file into a .brd to make it view by openboardview?
                    No water at all, nothing seems damaged so far.
                    Just 8 keys not working at all: y, h, n, u, j, m, 6, 7.

                      those keys may well be grouped together . if so the common connection is suspect .

                        They are grouped together. I still suspect the connector.

                        OP:
                        Do you have another flat flex cable with the same pin pitch and count? If yes, measure continuity through the cable to the connector. I'm pretty sure there's one pin that doesn't make contact inside the connector.

                          Tomorrow i'll try to make the KB flex a little bit thicker to make better contact. If it doesn't change anything, do you suggest me to solder each pin of KB flex cable directly to the corresponding pin on the board?

                            No, i wont do that. That would be quite messy and unprofessional. Replacing the connector would be the way to go. This would also make it way harder to replace the keyboard or disassemble the laptop again. You could either make the flex thicker or apply pressure with your finger on the connector. Just try everything you can imagine without breaking it

                              Conversion is a complex job, you first need to decode the fz with a python script and then manually convert it. every software has its use, I know opemboardview from the first releise and it was designed mainly for Mac boards.
                              I don't think the author is offended if you use other software as the .fz because of the key are not easily supported.

                                We already fixed the issue with the fz file and it works perfectly with fz key.
                                Sure, it has its problems but it does what it is supposed to.

                                  get the key and insert it in the code and then rebuild all.

                                    So made the flex thicker, changed nothing. The connector keyboard seems in perfect condition :s what would be your next move (don't have a keyboard connector in stock unfortunately and customer needs it urgently)? Thanks for your help

                                      Next step would be what I already said. Get another flex cable with both ends open and plug it into the connector. Now measure each pin between connector and flex cable. That would either prove a connection problem or dismiss it.

                                      If all pins are ok you most likely have a damaged EC. Highly unlikely but could be... You don't have any donor board with the same connector? There aren't many different types.

                                      Are you 1000% sure that both keyboards you tested are ok?

                                        I don't think i have a both ends open similar flex cable but will double check it.

                                        Will double check for same connector, so suggest me to replace it, right?

                                        I can assume yes as the guy who sold it to us explained he had exactly the same issue on the PC he wanted to replace it (so if both keyboards have exact same issue knowing it happens with no particular reason, most probably a board level issue, right?)

                                          If a new connector & keyboard doesn't fix the issue the problem will be somewhere else. Probably the EC. You should invest in a keyboard tester
