keyboard/trackpad unresponsive. usb mouse/keyboard not working

Hi everyone. I have a 2009 Macbook Air and the keyboard/trackpad have become unresponsive. They do not work at all at any time of the boot process.

I also have tried an external keyboard and mouse both of which do NOT work. It boots up to the password screen and thats as far as i can get.

Anyone got any ideas? all i can see around forums is fixes for this issue when an en external keyboard/mouse works

Thanks in advance for any help you can give me.

Did your system get wet some how? Something spilled into it or do you sit it down on a wet surface?

When you get to the password screen do you see dots showing up in the dialog box as you type the password? If you do, the issue is the hardware password has been set and you need to resolve that issue (not a hardware issue).

I cannot type anything in the dialogue box as the keyboard or trackpad do not work at any time of the boot process

I'm talking about after the system has booted up and you get the dialog screen asking for the password. Do you see the dots as you type? If not then you have both an internal keyboard issue and an external USB ports issue, that would imply the platform controller chip could be bad as both inputs connect to it. Then its time for a new logic board.

Also try using an external keyboard and let us know your results.
