How confirm which side's problem when keyboard not working?
Hello.
I have a Toshiba A200 laptop and it has problem that some keys not working.
Not working keys are F7, 7, U, J, M. It's in a column. So I can assume matrix is broken.
What I wonder is, how to confirm it's a problem of which side. Keyboard part? or mobo part?
Because it looks like keyboard part's problem, but I guess when pin of connector or line in mobo is broken should have same symptom.
I have a multimeter, so I can check disconnection some line or pin if I know which part I should.
Please help me how to check.
