I agree that the chain of exploits you're mentioning is unlikely.

But it's also possible there was no malicious FLAC file and that first my router was attacked, and then I was attacked via AMD PSP which hacked the firmware of SSD drive and this firmware tried to transfer the firmware attack to the second laptop.

I also plugged in the same ethernet device into both laptops at one point (to try to get the hacked router to work) and it could have been a badusb firmware attack or at attack that came from the router to both laptops.

Would 2 keyboards fail in the exact same way, with all caps and shift held down, but one is persistent after reboots and one isn't? It doesn't make sense.

Is this a typical pattern for keyboard controller failure that could be seen in this same way on two laptops at the same time?

    I mean, I think it's much more likely that some hardware failed, than that someone executed a highly sophisticated attack that worked but ended up showing obvious signs of tampering.
