Boot Keystrokes done work on internal Keyboard

[ethanh100]

Hello, I have an Air early 2015 and for some reason when I try to do any sort of key stroke on startup, such as holding option to select boot drive it just doesnt work. However when I plug in an external keyboard it works just fine. Does anyone know whats going on here? What can I do to fix this?

Try resetting the pram with the external keyboard by pressing Command-Option-P-R.
