Hello and Happy New Year! So, I have had this X54H laptop for about a year now, bought it used at a very good price for the performance, but since it arrived it had one issue: the left trackpad button wasn't working. So, now that I had some free time, I decided to open it up and fix it. To my suprise, the buttons were soldered on to the Motherboard. So, I went to a local electronics shop and bought me a similar button to the broken one, the difference being in the fact that the new one is missing a 5th pin. I hoped it would work just fine, but when I went to solder it on the Motherboard, two copper pads came off.

Now, I started looking for a schematic, which I actually found and used to solder some wires to connect the button pins to the needed signal creators. The schematic will be in the attachments below. I had to replace SW3101, but both the LEFT copper pads came off, so I soldered the LEFT pins from the button together and soldered a copper wire to the chip creating the signal from the bottom side of the board (forgot its name, I'm writing this from my phone and I can't view the schematic right now). The LEFT signal is indeed being triggered, only issue is that it's always triggered, regardless of the physical press. Why is this and how can I fix this?

 

hi antoniu,
Welcome to AAC.
Extracted your rar file, inside is a.fz file which I do not want to open.
Please post a simple gif or jpg image of the PCB.

That .fz file is a boardview file. I do not have a 4K display to make a print screen of the content that is in that file, so either you'll have to be ok with the fz or the Print Screen in 1360x768 I will take of that file, or I'm affraid you won't be able to help me. The fz file is not executable, it cannot harm and can only be opened with a program called "BoardViewer", Open BoardView doesn't open it, I tried it, but it spits an error when loading this file.

Please have second thoughts about opening that file, search about the file extension.

I will, however, take a Print Screen, but I felt like I needed to say this.

 

hi antonio,
Found the Board Viewer program, but it is saying I have download and install, it will not open online.
Perhaps another member may have Board Viewer installed and will post an image.

I have it already, but I will only be able to post the image in 9-10 hours from now, so, if you're affraid you might get into a virus, I'll take a Print Screen. Please consider, again, opening both that program and the fz file, as you won't see too much on that Print Screen. You can scan the rar archive and the zip archive you will download (because the link in the BoardViewer site will give you a zip file) with ESET's online scanner here:

The requested Print Screens

The red part is the component selected by me and the yellow ones are the ones that transmit the same signal.
