    I just got my week 20, black 2.0Ghz Macbook back from repair (two-day turnaround). I have original Apple-provided RAM and have never installed bootcamp (to dispel some of the theories floating around).

    I'm happy with the speedy service, but not so happy to see that they only replaced:

    APP-605-0928 SVC, TOP CASE W/KEY BOARD, BES

    I send my machine in because it randomly shuts down on me, and they replace the keyboard? ***?

    Anyway, I'll be working on it today waiting to see if the shut down occurs again. BTW, I've never been able to trigger it by doing the yes > /dev/null command trick. My machine has shut off first thing in the morning, while reading email, and late in the day when I've got lots of other apps running. Doesn't seem to make a difference.

    My Macbook is back after the 2nd repair (sent to Memphis, Flextronics) for the random shutdown issue

    To date, I have had the following parts replaced:

    Repair #1 (July)- APP-630-7691 PCB MLB, 2.0GHZ DC, APP-590-5254 PWR CRD, GND AC ADPTR, NMP, US

    Repair #2 (August)- APP-603-9857 ASSY, BEZEL, M42 APP-605-0994 SVC, TOP CASE W

    Considering what I'm reading about similar repairs to other posters' machines, I won't be surprised if the shutdowns start up again.

    I guess new RAM and a HD would be the next thing to replace. It seems Apple is still not sure what is causing the shutdowns

    One other thing, some posters have noted that it's a minority of MacBook owners that are having problems with their machines and that's probably correct. However, in the last few weeks I've talked to 4 people who have experienced random shutdowns but haven't considered it enough of a problem to contact Apple.

    I sent in my MacBook on July 26th (arriving on the 28th) and after I called up AppleCare about 4 times and waiting on average a half-hour on hold (today I waited 1 hour 30 mins), they finally got my MacBook off of hold (awaiting a part) and sent it out. All of my whinning finally paid off. I thought i was never gonna get my computer back, especially since I leave wednesday for college ! (phew)... They said that they were backed up on heat sinks... So when i get my computer on monday I'll post back and let everyone know...

    I purchased my white MacBook June 16th, it arrived while I was out of the country until July 5th. I started using it on the 7th and I would say the random shutdowns started about the 11th or 12th. I finally took it in to the Apple Store on July 28. It was returned to them on August 9th and they did a check and found it would not start from the battery, which was a new problem. They sent it back on Aug 10th. The level 2 person said no parts were on back order and I should have it back in 4 or 5 days. Today is August 19th and the repair status indicates "on hold-part on order". I have requested a new computer 3 times but they absolutely refuse to consider it until the computer has been repaired 3 times. I am sure that i have a lemon and I'm never going to trust it. I paid nearly $2,000.00 for a computer that has had problems from the beginning. It is obvious that this is a big problem when you read all of the postings. When you talk to the Apple CAre people they seem surprised - they also say they never read the discussions postings! I just can't believe this is the same Apple Computer Company that I have been doing business with since I purchased an Apple 2e!

    Good news. My macbook is back on Friday in 5 days (I left with the tech on Monday). Only part replaced is the logicboard. It is working perfect with all the ususal programs. I even used the external firewire drive to move files back and forth with no shutdowns. I installed the 10.4.7 update and also the new smc firmware update (I recommend it, it really cools the MB with the fan at a regular speed, very quitely, you won't hear it unless you put your ear on the keyboard).
    Here is what I learned.
    1. The random shutdown is a symptom, not a diagnosis. The same symptom can have many diagnosis. (Not everyone with a cough has lung cancer!)
    2. The symptom is one of hardware problem (could be anything, battery, RAM, logicboard, fan, heatsink etc. but most often it is the logicboard. If it is the battery you will know because it wouldn't happen when power is connected.)
    3. Try reset PMU, PRAM etc and if you know how to check that the RAM is seated properly etc and then call apple support and get a case number before you take it to the tech in the apple shop.
    4. 10.4.6 or 10.4.7 has nothing to do with it so go ahead and update.
    5. The fan firmware update is worth a try before taking it to the shop.
    6. Finally, take it to the tech early in the week and ring daily to let them know that you really need it and anxious to know what is going on..
    7. Good luck. Don't try to fix it yourself, it is a new computer and you have warranty.

    I agree with most of what you say in your post, but what is the basis for your statement that it is most likely the logicboard, you say you learned this.... from Apple?

    Following the posts here and on numerous other threads related to random shutdowns documenting the type of repairs people have reported, it doesn't seem that there is any particular repair or part that has successfully addressed the problem. Logic board replacement didn't help me out. My MacBook started having problems again a couple of weeks after a logic board replacement. It appears that Apple may still be trying to figure out what is happening.

    I learned from reading through these forums, talking to the guy who fixed mine and that my MB is working well only with lb replacement.
    What the guy said was, any shutdown like this with no warning is hardware fault rather than software. Once they run the apple diagnostics at the bar they will know the culprit. It could be as simple as a poorly seated ram to a faulty logic board. If it goes to the main centre where all parts are available just sitting on the shelf, they will replace all the likely culprits rather than the most likely one. If your local shop had to repair it by ordering a part, they are most likely to order the logic board. If it doesn't work you might have to send it back to the service centre for more extensive replacements and if that doesn't work they will have to give you a new book. Just keep sending it back until you are 100% satsfied. Persistence pays.

    Which means how many weeks had you owned your MacBook when you got it replaced?

    Your first repair looks similar to mine (though mine did not list the logic board - mine only listed APP-590-5254 PWR CRD, GND AC ADPTR, NMP, US). Sounds like that didn't work for you. Do you have any idea what NMP or US are? Did you start having random shutdowns again after you got it back, or did you send it back for a different problem? If you were having shutdowns, how long was it after you got it back that it started having problems?

    I've had mine back from Flextronics for 1 1/2 weeks and so far, so good. Did get one instance of vertical lines, but that was fixed with a PRAM reset. The temperature was still pretty hot (and personally I think the heat is what has been damaging the internal components), but I just installed the new firmware update and that seems to have cooled things considerably.

    My week 22 black MacBook started having both cold an hot random shutdowns after about one month of operation (right after the upgrade to 10.4.7). It then elevated to rapid restarts during boot (kind of a circular crash pattern), and finally to no boot with the multicolored vertical lines. When I took it to the local Apple Store they agreed to give me a replacement but not from store stock since mine was an online order. Apple sent me a new week 29 but I had to wait for it to be built. So far it has not had the random shutdowns. I did not upgrade to 10.4.7 on the new one until yesterday as I was afraid that was the culprit. I went ahead and upgraded yesterday as the firmware update will not run on 10.4.6. The firmware update seems to be helpful. It has only been three weeks with the replacement laptop. It took four weeks before I started having problems with my week 22 MacBook. I am hoping that they have resolved the problem. Keeping my fingers crossed.

    I don't believe I'm speaking for myself
    when I say, I can't just send it off for however
    long they feel necessary. Apple has to step up and
    realize that there is something more wrong than a
    hard drive... Any one agree?


    yes, it's indeed true on that. i myself bring my macbook everyday everywhere i go, and relying it on taking notes and doing my work every single day. i definitely can't afford to always having to send my macbook in every now and then for them to play around, and experimenting... that reminds me of having to spend the money to buy a hardware so that the manufacturer can continue experimenting at my expense... i'm no rich guinea pig... thought we already have, in a way, paid for the research-n-development deparment when we purchase an item from apple? can't apple just find out what's really gone wrong, or at least try, instead of testing here and there?...

    Hey all, thanx for making this thread. Its been really helpful for me to read thru it. I have a white MacBook, week 22, 2.0ghz that im going to need to send away soon, for it started crashing last week.

    This is a real bummer. Ive owned all sorts of glitchy computers, and this Mac was sort of my last resort. Both my PC's are dead right now, and school starts in one week. If i dont have this mac, im in BIG trouble. I hope Apple support can do something about this!!

    When i get it repaired, i will post the replaced parts..

    Just received my Week 25 back from Flextronics. Problems were Random Shutdown, Excessive Heat, Discoloration, Jumpy Cursor...The parts that were replaced are:

    APP-605-0994 SVC,TOP CASE W APP-603-8071 ASSY, HEATSINK
    M42 APP-603-9857 ASSY, BEZEL, M42

    The shipping seal was compromised when I received it. When I powered the MB up, I got nothing but a gray screen for two - three minutes. I powered off, turned back on, and all I have now is 2/3 of the screen covered with the vertical colored lines and the other 1/3 is gray.

    AppleCare is going to pick up the computer again and try to fix.

    Shipped to Apple on 17-Aug, repair (sic) was completed 18-Aug, received it 22-Aug
