What I've done is soldered new Gateron black switches on my G80-1800 HAD PCB (Thanks for the free PCB and Case Khers ). The PCB came without jumpers so I've soldered on 1N4148 diodes in their place. I did not solder diodes in the switches which have no traces going in or out of them.

Pic in spoiler When I started my PC with the keyboard connected to my PS/2 port with DIN->PS/2 adapter I hear som strange klicking noises from the casemounted speaker inside the computer chassie. When Windows login screen appears I can't enter any letters. The keyboard does nothing.

I opened it up and noticed that I had forgot to solder a diode, fixed it, but the same thing happened again.

I borrowed a Multimeter from my job and checked to see if had accidentally toasted a diode. But all seems fine. I checked all of the switches to see if any of them were pressed (on) by default, and all of them seem to be working properly.

What's to next step in troubleshooting this?

Edit:

After a week of my kitchen looking like this (GF not very plesed )

I couldn't find out what's wrong so I made my self another Soarer converter with a spare Teensy I had laying around.


And much to my surprise it came alive!


Typing this post on it now and I'm very pleased. Seems like either the blue cube or the DIN/PS2 adapter doesn't like this board. Both of the adaptors work with my G80-1501. Weird ...

Now I've got to program some special custom layers and stuff since it's got a fancy new Soarers adapter .

Removing all diodes and putting in jumpers.
You can't blindly replace jumpers with diodes. Sometimes current needs to go both ways.

Thanks for your quick reply. That makes sense. I'll try that tomorrow .

So I took of all the diodes and replaced them with cut of pieces of diode legs. The problem remains, Strange clicking noises from the speaker and then nothing.

I'll either buy my own cheapo multimeter or borrow one from work so I can check for continuity. The solder pads are getting slightly worn so there might be some bad solder joints. Apart from that is there anything else that I could do?

Update: I bought a multimeter. Bent new jumpers and replaced the shitty looking ones i'd bent before. Resoldered all of the jumpers. Checked for continuity. The matrix seems to be intact. But still getting the same problems as before when I plug it in to my PS/2 port.

Got it hocked up to my computer now using a Bluecube PS/2->USB converter. I can now make the LEDs blink by pressing any of the 3 lock buttons (Yey! ). The LEDs doesn't stay on nor do they blink if i press the lock buttons on my SSK connected to the PS/2 port.

What now? Any suggestions are welcome!
