Got a used Thinkpad Yoga S1 12 at the beginning of 2020, working all fine, but now the "A" key needs to be pushed a special way to work. - Which is of course very troublesome, especially when translating.
The key press feels normal, just as all the others.
I have tried to push lots of air into that key from all angles... maybe there is some dirt underneath the key? --> No change.
Also I did rotate the display to make the thing tablet, and vice versa while directing compressed air in/on that "a" key. --> No change.
grr.. next step would be to unscrew the whole thing (I've seen the maintenance manual.. uff..) just to see the keyboard from underneath.. - But question is (and this is why I am writing this).. did anybody do that already on that notebook?
Good chance, the keyboard is built in "as one piece", and one cannot look underneath the keys... which would render the whole action a waste of time. - Instead I'd get a new keyboard and THEN unscrew everything, and replace the damn thing.
But then again, if anybody did this already, and the keyboard CAN be maintained and revived, getting a new one would be a waste of money..
So.. any hints welcome. : )
