Lucky me. I've got one of the new 125's with a bad logic board causing it to loose the pro speaker connection on sleep and restart.

Is this something that can be repaired while I wait or not? And, what other symptoms might a bad board have?

A Logic Board is a Mother Board. Does that help?

Lose the attitude. You want people to help you here, you're gonna have to be polite about it. How old are you? Three?

He answered your question exactly as you asked it.

A logic board is a motherboard.

Other signs of a bad board would be crashing/kernel panics, failure to boot, etc. I don't know anything more specific - the machines haven't been out long enough.

No, it cannot be "fixed" while you wait. Your machine will be sent away and the motherboard likely replaced.

Thanks Cipher.

Thankfully, Apple has graciously agreed to swap out the machine. I just have to wait for their inventory to clear out of the suspected s# series.

Good to hear.

Count your blessings... Apple isn't usually so cooperative.

Thought you might enjoy an update...

Just last night I picked up my new 1.25 with a serial of x305 to replace my x304 and low and behold speakers are recognised on restarts. Not only that, this model is actually considerably quieter! Coincidence? Probably. I couldn't be happier.

The tech at the Apple store was kind enough to swap out the hard drives so as much as enjoy the set up of a new system I didn't have to and was able to jump right into these boards first thing this morning

Not an unusual problem (but rare). Since it's a new system you should be coverred for the repairs. This is why I always stress that when you get a new mac test drive the crap out of it. Push it to it's limits. Unless you're wealthy enough to fork out for extra applecare, they still only cover for (?) 30 days (or is it 90?).

I was able to get an on-site tech to make a housecall at a former job of mine on a new G4 server. I dunno if they only do this for businesses or if they'll actually come to your home and do the same thing. I can't see why it would be any different. These techs are usually sub-contracted from Apple, but they do know thier stuff. The bottom line also is that Apple pays them for the "house-call" and you pay nothing.

If you can't take it somewhere to be serviced I'd suggest calling Apple support and finding out if they can send someone over to your home/business to fix it.

Did they give you a new board or an entire computer?

The thing that came to mind when I read the title of this thread was "What's a truck?" "What's a murder?"
