Keyboard Keys Only Work with Fn or Shift - Certain Keys Not Working Normally (ROG Strix G614JV)

[M0rpheus1]

Problem Description:

• Certain letter keys on my laptop keyboard (specifically M, V, Q, , . , C) do not work when pressed normally.

• These keys only register when pressed together with Fn or Shift.

• Other keys work fine as expected.

• I have tried:

  • Uninstalling and reinstalling all keyboard drivers.

  • Resetting BIOS to optimized defaults.

  • Reinstalling System Control Interface drivers.

  • Checking for any Fn-lock toggles (Fn+Esc etc.).

  • Testing with an external USB keyboard (which works perfectly).

• I suspect it might be related to either keyboard hardware damage or a ribbon cable connection issue inside the laptop.
  
  

  What I Want:

  • How to fix this so the keys work normally without needing to press Fn or Shift.

  • How to check or fix potential ribbon cable issues myself if possible.

  • Any BIOS or software settings that might cause this strange "secondary layer" behavior.
