A1200 Keyboard Diagnosis
My A1200 has in the past lost a few keys when I haven't used it for a while (like days), they eventually come back after a few hours. Just wondering if I can diagnose where the issue is (membrane, connector, controller etc...)
I've not used it for a Month or so, and currently it is refusing to co-operate, it really is a twat sometimes. I have cleaned and re-seated the ribbon cable, and it looks good - so I don't think that is the issue. I have an A500 in the cave - can I test that keyboard on an A1200 to start to isolate the issue? i.e. is it "plug compatible"? Diagrom: no issues (other than the keys not registering) It is normally the same keys that drop out, I looked at the schematics to see if it gave any clues as to maybe a specific trace is flaky but they are not very helpful. Keys that are out: F10 Del Keypad: 0 (zero) Enter (not the keypad one) Backspace and |\ (next to backspace) Does that give any useful clues? (probably not) Thanks all Also have an A600 I could swap the keyboard from. |

Obviously having just written this the little twat has decided to re-enable the lost keys, it's been switched on for about 3 to 4 hours running diagrom and with me poking/cleaning etc......none of which made any difference, until leaving it alone to sulk for a bit.
Question still stands though. And yes it's recapped. |

The one thing I think I can conclude is that it's not the membrane if all the missing keys came back at the same time? true?
