820-2877-B Keyboard/Power Button Trouble

With the keyboard plugged in, it doesn't boot when I press the power button or short the pads. With the keyboard unplugged, I can short the pads and it works great minus the keyboard. If I short the pads and then quickly plug in the keyboard everything works great, including the keyboard. If I then click sleep at the login screen with the keyboard plugged in, it hard shuts down (hard drive does the click sound) but it does a normal sleep when it is not plugged in. If I hold down the power button at the login screen it will do a hard shutdown so it seems that the power button is indeed working (sorta). But if I then push it to turn it back on I get nothing. Am I right in assuming it is the keyboard itself that is bad? I got it from another store who just did a keyboard swap and are looking for a second opinion. Thanks in advance.

Looks like the keyboard to me. You can connect any A1278/A1286 keyboard to check, the pinout on them is all the same.
