Keyboard needs to 'warm up' before working?
« on: Thu, 14 June 2018, 11:12:22 »
Having a strange problem with my Cherry MX 3000. In the morning, when I first type on it, certain keys, such as the "a", "t", "u" and right shift keys do not respond at first. It seems like after 2-5 minutes, all the keys then work fine, almost as if the keyboard needs to 'warm up' before functioning properly. I initially thought I need to blow some dirt out from under the keys and the switches but it seems clean and the problem seems to fix itself just by me leaving the keyboard on for a few minutes. Ever heard of something like this? I don't see any easy way to open this thing up and look at the board itself, so either way I guess I have to live with it.

hahaha. no,, it's probably a cold joint near the controller  or a cracked trace.

take it apart look at the pcb, follow the traces coming from those switches..

Thanks. Ah, you mean like something needs reflowing? Could be. I'll see if I can figure out a way to open it up. There's plastic latches instead of screws.
