Hi all... I am new to the Mac world, but have been in the industry for 20 years. Here is the issue I am having. I have an iMac (Intel based) that I am running into a serious problem with.
I power up the iMac and it boots fine, but I cannot use my mouse or keyboard. The keyboard is plugged into the back as is the mouse. The mouse lights up but doesnt move on the screen. Now the keyboard doesn't respond at all.. not even caps lock lights up.
The first thing I attempted was... Change both devices out. So I took my keyboard and mouse from my Dell and plugged them in... Nothing. Took the Mac's keyboard and mouse and plugged into the Dell and they work without any issues. So I am wondering maybe I need to repair something, so I put the Snow Leopard disc in the drive and booted. Now, the machine is set to boot straight to the hdd, and I cannot figure out how to make it boot to the disc without pressing and holding 'C' (since the keyboard doesnt work)

Anyone have any ideas?

Thanks
Michael

You have a hardware issue. None of these things should be happening. Call Apple right away. Apple will fix it if its under warranty or Applecare.

yes, I have tried unplugging for more than 5 mins. I have attempted SMC reset. I cant do PRAM because I cannot get the keyboard to register.

Is there a way to force the mac to boot to the dvd (without pressing anything)? maybe its a driver issue after an update or something.

Any way to pair a bluetooth KB and mouse with it? Probably not since you need to type in a PIN on the initial pairing. Sounds like you're SOL.
You can still pair Bluetooth without the need of a USB keyboard.
You will type the PIN from the Bluetooth KB.

It seems theyre getting power, could be a intermittent issue, but most likely the Logic Board will be replaced.
