Title: [Help] Problem with Noppoo choc mini Blue Switch
Post by: Solanin on Sat, 11 February 2012, 03:28:24
My friend gave me his old Noppoo Choc min recently. However I noticed that the left Ctrl key has trouble getting recognized. Occasionally I have to push it down real hard and hold till it is recognized. So can anyone please kindly inform me what might have gone wrong with it and if possible, how can I fix it? Thanks in advance :(

Probably a faulty switch. Try to open(ply-off) the switch and reassemble it. If the problem persist, change the faulty switch(in this case change the stem)

Same thing with my Esc.

Open the switch and fix it/Replace the switch.

You will need to desolder the switch from the board, since it is plate mounted.
It will be hard to test without like a multimeter/scope/LED + signal/power source. So unless you have these, it'll be very hit and miss. Basically you want a easy way to debug whether the switch works while it is desoldered. If you can debug it easily, then when you open it, you can see whats going on. I think maybe the leaf contact might of bent a bit (happened to mine).

Yeah also Welcome to GH.

If you have problems, just repost here or PM me. Will try to save your keyboard = ).

Don't be afraid of soldering, it's rather easy.

Thanks. . . . hazeluff. It came out quicker than I thought it would be. However the switch seems to be broken so I replaced it with a cherry MX brown, work like a charm :D
