    mine is doing it too

    has anyone ever got this repaired?
    it happens so randomly and i dont see the point of
    giving it to a service (to reduce the small amount of
    occasional shutdowns) as long as no one really knows
    what it comes from. i paid to use it not to wait for
    it


    The Apple repair fixes the shutdowns, at least from what I have seen in school labs. Alternately, if you are comfortable at computer disassembly, you can potentially fix the problem yourself by breaking the glue that holds the sensor wires to the heatsink's side, and nudging the wires away from that area. So far, this works with the computers I have personally seen.

    Your choice...

    Eventually, as the wires' insulation compromises at the heat contact point, the shut downs will increase.

    thanks for that insight. I must say that my new macbook does NOT seem to only shut down when it gets hot. Indeed, as others have mentioned, it often shuts down after having woken up from sleep.

    Does anyone know how long this takes to repair? i am in Italy and will be back in the states for one week. Does it make sense for me to take it into a mac dealer, or will they need it for more than a week?

    thx also...has anyone found a reason why it happens when it is cold?
    i mean...really cold, it seems it happens to many people when its really cold.
    is there maybe another sensor involved, such as the sudden motion sensor?

    That's right. In my case, it would shut down a soon as the grey screen appeared. And after repair, it wouldn't boot at all. That has little to do with heat...

    My Macbook (purchased in May/June) did it's first random shut down about a month ago, then a few days ago, and again today. It's a pattern that's getting more frequent.

    Obviously the answer is going to be sending it for repair, which is going to be really annoying as they don't provide a 'loan unit' or any compensation for being without it during the repair period.

    However, what I'm really concerned about is whether a 'repair' could actually make the problem worse. So far it's really not been a major inconvenience, but obviously I don't want to wait until the warranty ends only to find it's happening too frequently.

    Any comments?

    I have had to send my Macbook back 3 times for repair trackpad button, repair optical (DVD) drive scratching my discs, and shutdown problem. So definitely a loaner would have made my Macbook experience positive.

    My prior experience sending it back, repair status at https://support.apple.com/repairstatus/ would give details like product received by repair center, ordering parts, etc. Now status just reports repair in progress for days.

    I hope this response answers a few of the above questions:

    My May-purchased MacBook began shutdowns when hot, then shutdown when cold and hot; the repair shop replaced the logic board and the heatsink - first the logic board, it wouldnt turn on...then a week later, the heatsink, since then it has worked fine. So, to all of you:

    Request a logic board and a heatsink to be ordered by the repair facility, (guy from Italy especially) and if you're in luck it will take a week. They will not usually keep parts in stock so the order goes in when your MacBook lands on the repair desk.

    good luck, the logic board/heatsink repair works. Remember to back up or copy all your important data to a CD before you bring it in because some repair facilities erase the disk and reinsta the operating system (unnecessary but some do it, so better be safe than sorry).

    From Cork, Ireland

    I bought a Macbook on June 30th. Shut-downs started mid-September. Left in for repair at Apple dealer on Sept. 27th.

    Got a call yesterday (Oct. 24th.) to say unit was repaired with replaced heat sink. Tried it while at the shop - it didn't start up and I noticed a sizable gap in the case. So I left it with them.

    Now it's in for "logic board replacement" with no estimate for repair.

    Result, 4 month old laptop, in for repair 1 month + (25% of lifetime) = lack of happiness and envy of users in US with access to Apple Store, feedback and rapid turn-around.

    As Apple becomes more successful and competitive is quality suffering?

    I have been using/buying/recommending Macs since 1980's (Mac SE) and this is my first lemon, so I hope it's just a blip but from now on I will probably stay away from rev. A machines and from the cheapest in the range.

    All the best.

    The logic board is a quick replacement (mine was), but its essential to have a logic board and heatsink replacement, not one or the other. My MacBook runs very cool now, even at peak use, and XP runs beautifully on the other partition, which is great because I use both OS in my instructional design work.

    i ordered at a gravis shop and i already had to replace the superdrive as it wouldnt read some cds

    i brought the book in there and showed the problem. then they ordered a replacement drive . i made an appointment with their service for the time the drive was securely expected to be there and then had the replacement done in one day. why should that not be done again in a similar way for anyone who bought at a regular shop - as long as the reason for the problem is known

    Either a superdrive works or it doesnt, but the random shutdowns have been far more complex, affecting the operating system and associated hardware. Until recently, even the "new" replacement logic boards also created the problem. I understand a new logic board version was issued to replace the older boards in stock. Who knows, Apple may be at the point of sending out logic board/heatsink "kits" to shops, but until then we have to bring in the MacBook and demonstrate the random shutdown before parts are ordered. I was fortunate, my MacBook did it for them, then the tech suggested I take it home and bring it back when the parts arrived.

    This should not be necessary. The Apple genius took a look at some log to see a random shutdown occurred and took it for repairs.

    Have been seeing this also. Boots to dim blue screen or is on and won't shut off with LED in front on when you close the LCD. Also boots to a white screen sometimes or wakes to a white screen. I've replaced logic boards and this still occurs at times. What I've found to temporarily fix this is to hold the power button down till the MacBook shuts off. Then start the MacBook and reset PRAM. Once you do this, boots fine and stay running. After replacing logic board and heatsink, this has improved, but not completely. Resetting PRAM does fix till the next time though. Customers out here and been able to perform this and stay working. I've explained that Apple is working on it and we are moving forward till an official fix comes out. Hope this helps.

    My understanding is that you only need the heatsink replaced to fix Random Shutdown.

    It appears now to be a definitive solution and most people who have had their heastsink replaced recently have NOT had a Random Shutdown since.

    thats why im asking if there is a clear solution for it.
    no doubt this problem is not one that is specific for my laptop

    the superdrive ran most times, it was only a few cds it couldnt read for strange reasons. this wasnt an issue of my book either, i found lots of other people haviong the same problem too in the net. at first, they couldnt even find the bug - until i brought one specific, commercial, brandnew cd, that the macbook would never read, but all other computers would

    i would expect them to believe me i have those sudden shutdowns due to what goes on here in the net and "hope" i can make it a reproduceable bug. how else could things work out? i cant waste hours trying to make a young kid in the shop believe that my machine does shutdown occasionally and he tries to find the mistake all on his own while the whole world didnt solve the problem yet.....while i wait for hours? i could get a heartattack from that. i only have occasional shutdowns, but i want to use the macbook for live musical and dj performances. it feels i cant do that right now, i cant trust it. but if new logic board s dont solve the problem totally, there is no use in getting one now and its better to wait at least a bit until there is an agreed explanation...ill use the laptop for my office work as i do now...but i invested in a 7200rpm drive, 3 year warranty + 2gb and the 2ghz model etc... so one day in the next months i want to be ready to use it for the purpose i bought it for.
