    after several kernel panics. Noticed some heating up to 186 degrees F and fans getting to 6200rpms. Also video iChat is still "jacked." Can't make any changes in preferences w/o a freezing and kernel protection failure. :(

    Sounds like you have one with an improperly installed CPU heat sink. Good luck and keep us posted.

    Yup, I'm having them check it out right now; wish I had video. I'll keep you all posted.

    You mean thermal paste? It's a known issue that too much is applied on some units thus becoming an insulter of heat. Re-applying reduces heat by 5~8º C

    That's one possibility. It could also be the CPU socket lifted from the circuit board. Or blocked vents while in use... Anybody's guess until we hear back.

    On its way to get fixed with a 5-7 day turn around. Who knows what was going on with it, but the temperature ranged from 165ºF - 212ºF and fans were 6200rpms - 7200 rpms. Everything was backed up last night, so I was ready to ship it this time, since all the others were fixed at the Apple Store, but not really fixed. I'll keep all of you advised on the situation...:(

    Wow! 212F is 100C! Sounds like something definitely wrong there. They may replace your motherboard. Let us know

    They seemed optimistic that they could reduce the heat, but couldn't figure what was going on with the kernel panics and kernel protection failures. The Tech person was adamant that I would get a replacement if the problems persisted. Of course, I'm leaning towards the MBAir Unibody 1.86/128GBSSD, even if there's a bump in price with my 1.8/64GBSSD

    Matter of opinion, if you asked me. If you'll notice that no mention of the unibody construction for the MacBook Air is available until the release of the "unibody MB and MBP" while the rev A MacBook Air has no mention of the unibody construction until after the fact and even that is described by Apple outsiders. Not even the refurbished rev A makes mention of its unibody construction according to Apple's Online Store...:eek:

    First MacBook Air was unibody. There is no difference to the outside of the 2 models except the mini display port. Apple just didn't start using the word unibody until the new MacBook and MacBook Pro came out.

    Just because they didn't call it unibody doesn't mean it wasn't.

    PS: Good luck with your Air

    Yea if you watched the boring part of the Macworld conference when they showed the macbook being made in the factory the speaker actually said they had started using the process with the first gen macbook air. :)

    Sorry, but I seemed to have missed anything "boring" about MWSF '09...:D

    if they CRU your machine (customer replacement unit), they will automatically upgrade your machine to the 'same' tier of the current line....if you have a Rev A MBAir with SSD, then they will replace yours with a Rev B SSD :)

    did you try creating a new user account to replicate the issues? this should have been the first thing that the genius attempted at the bar. If the issues persisted in a new user account, the next step would be to boot off of an external OS and attempt to re-create the issues....if the issues persisted off of an external OS, then it would be your hardware 100%...the next step would replacing your your MLB for sure...

    if it was just the heat issues, then they might move towards a new heatsync...but since your issues are coupled with KPs, an MLB would be the logical choice..

    after replacing your MLB, if your issues persisted, they will probably replace your unit or ship it to depot.

    good luck :)

    UPDATED: MBAir on it's way back...

    from Apple and it appears that it took two days to arrive at Apple's Repair Center. Repaired and left Apple today and is on it's way to my residence via Fedex.

    Here's the Repair Order Description:
    Unit has KPd multiple times in the past several days, even after reinstalling OS. UKPs occur more often when unit is hot and temp of unit is higher than expected during general to heavy use. Steps to Reproduce: Run video from iSight (issues seen running iChat prior to checkin), stress system. Troubleshooting Steps: Unable to reproduce issues during GB session (actually it did get reproduced, but apparently he had already made this entry). Time to Failure: Ten minutes or more (exactly 10 minutes and it appeared). Unsuccessful Fixes Attempted: Archive install performed two times. Cosmetic Condition at Genius Bar: Very Good (He mentioned "immaculate"). CS Code Number: N, User Name: Auto, Known Liquid Damage: N, Other Notes: N

    Pretty interesting Repair Order. Waiting for the FEDEX Truck to come driving up the driveway at 8:30am...:eek:

    interesting choice by the genius team to re-install the OS without checking from an external OS (a waste of time, for sure, to re-install OS without checking off of an external)...also, slightly odd for them to NOT install the MLB in store...either the team does not have a solid MBAir repair person (i was the Air specialist at my store :D ) or they are swamped with repairs..

    some apple store teams send units off to depot consistently, but most try to do every repair in-store...

    either way, you'll get it back from the FLEX depot in working condition :) it is also nice to know that if any problems persist, or if any NEW problems should occur, they will have NO CHOICE but to CRU the machine and you'll get a new rev B :)

    good luck on the quick turn-around time

    Thanks for your comments, I was a bit surprised that the GB was so quick to get me out the door. There was no line and many people were not showing up for their appointments. Totally handled differently when my MBP which arrived with a non-operational battery, was DOA and everything was overnight v. "you get it when you get it" but then again it was coming from the Depot. I'll keep you advised...

    they did a CUSTOMER depot? as in, they are sending it to your home??

    that is actually unusual for something like this...most of the time they do depot repair-store, so they can run some extra diagnostics and make sure depot fixed the issue...

    methinks you were dealing with a newbie genius at the bar :rolleyes:

    I'm thinkin' you're right on in your estimation of the GB dude. Very little attention to detail by the GB dude and he seemed dispassionate and didn't do any feedback conversation, as to what he thought the repair would entail beyond the heat and kernel panic issues would be addressed and that I might be looking at a replacement. Our final conversation was: "Would you like to have your MBAir delivered by Fedex to your home or the Apple Store?" and of course I said "my home would be most appreciated."

    Thanks again, for your insight and advice "AIRniloc" :cool:

    I'd say the reason for kernel panics is most likely excessive heat :eek: I'd say your CPU, your memory, your hard drive, they are all not too happy about excessive temperatures.

    +1 ^^^ Though there has been no definitive reason or answer to a kernel panic; I tend to believe that excessive heat is a key factor with much if not all my troubles...:eek:
