Hi everyone
I got my hands on a Dell AT102W keyboard that uses Alps black key switches. It has a PS/2 connector so I bought an active converter to USB. When connecting to a computer, the keyboard remains unresponsive: none of the LED's light up, none of the keys work, nothing. I tried with other known good converters and other computers, but nothing happens.
It was used on a daily basis back in the day and has been collecting dust for quite a few years. My first response was to blow it out and check the capacitors inside. They all seem fine, except for two (presumably) 50nF capacitors, which I'm unable to test reliably, but show no physical damage.
Does anyone have any idea to resurrect this keyboard from the dead? Has anyone heard from similar issues?
The switches feel so nice and I would like to use it some day.
Happy to share more detailed information if necessary.
Kind regards
