Keyboard vs keyboard controller

[Cygnata]

If a laptop keyboard passes the PC-Doctor non-interactive testing, but fails the interactive completely, is it safe to assume the issue is the keyboard itself and not the controller? I need to get this one right on the first try or I'm going to have a VERY annoyed customer. Thanks!

That sounds like a safe assumption, but I would ask for clarification on how the interactive test is failing. Some laptops require the use of the "fn" key to allow complete testing of the keyboards.

[Cygnata]

All keys take several presses to respond, if they respond at all, with or without the Fn key.

Then it certainly sounds like a keyboard issue to me.
Since you mentioned you didn't want to make a misdiagnosis, I would make sure to give both the keyboard and the controller a second run in DOS as well as Windows just to confirm.

I actually try to only run PC-Doctor from DOS. Thank you so much for the confirmation and quick reply. The customer has been called and hopefully he'll be pleased. $46 for a keyboard > $300ish for depot.
