Good day,
it just so happen that I got my hands on a Asus RoG Strix (GL553VD ~2017),
in absolute mint condition. But with a "dead" keyboard.
I checked all the obvious stuff:
Condition of the connectors, there is absolute ne evidence of liquid damage or mechanical stress. As mentioned, absolute mint condition, as it was actually never used.
All keys have no function at all, and doesn't work in the UEFI.
So I don't think it's an software/driver related issue.
I also set the UEFI to defaults to verify it's no software issue.
The only Key that works is the power button which is integrated in it, as well the power Led underneath.
But the touchpad is working but it has it's own ribbon cable probably internal USB.
So it's hard to believe that the keyboard is really broken, with noch evidence of external influence or even wear.
I've tried to measure the pins of the ribbon cable and see if I get any kind of reading by pressing an button.
Here I could get some changes in resistance linked to key presses.
Did you ever have "faulty" keyboard which was looking fine?
I've spotted close by an tinye ITE BGA IC (IT8176FN) which most probably the Keyboard controller, because according to the datasheet it features such.
But is has also a PWM controller and other functions in it I'm afraid I can't just replace it without flashing it.
Because I have a hard time to believe that the Keyboard is bad.
And a replacement top basecover with integrated keyboard is kinda expensive,
which is hard to justify just for testing.
Did anybody has some experiences he would like to share?
I've come across only partially failed keyboards or some with ghosting but not a completely dead one.
Any hint what I should look for or what I could check/verify?
Cheers.
