Just got my MacBook back from 2nd repair

I just got my MacBook back today. It just had its 2nd logic board replacement because of the random shutdown issue.
When I picked up my computer, they also replaced the Top Case Housing and the Keyboard. Why would the replace this? Does the keyboard and top housing have anything to do with the random shutdown?
Anyways, I will see if my random shutdown comes back. I surely hope not.

Oh ok. I noticed the feel of it is a bit different
than before.
Another question. I have CoreDuoTemp opened, my
computer has been on for 30mins and it only shows
22-27C. Is this correct? Or is CoreDuoTemp
malfunctioning?
At 30mins, my MacBook was at least at 45C always.
It's an Intel processor design fault. I got this info from the Hardware Monitor developer.
Q: I have a Mac with an Intel Core Solo or Core Duo processor.
Sometimes, the temperature readings seems to "hang" and are no longer
being refreshed. Is this a problem with the application?
A: No, this problem is caused by an internal design flaw of current
versions of Intel Core processors. The Digital Thermal Sensors may
stop working when the processor returns from a C3/C4 power saving
state. Intel plans to correct this hardware bug for future steppings
of the CPU.
Intel refers to this hardware problem as Erratum AE18. For detailed
information, please see Intel document 30922204

    I just got my Mac back from Apple repair and I can't burn a disc. What do I need to do to make that happen?

    Hello deneye2112,
    Thank you for providing the details of the burning issue you are experiencing.  I found some resources that I think might help:
    First, I recommend resetting the System Management Controller (SMC) on your Mac (I wasn't sure if you had a removable battery or a built in battery, so I listed the steps for both):
    Resetting the SMC on Mac portables with a battery you can remove
    Note: Learn about removing the battery on MacBook and MacBook Pro.
    Shut down the computer.
    Disconnect the MagSafe power adapter from the computer, if it's connected.
    Remove the battery.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Reconnect the battery and MagSafe power adapter.
    Press the power button to turn on the computer.
    Resetting the SMC on portables with a battery you should not remove on your ownNote: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer.
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
    You can find the full article here:
    Intel-based Macs: Resetting the System Management Controller (SMC)

    If you are still having trouble with burning after that step, I recommend reviewing the section titled "Top troubleshooting tips" in the following article:

  • Got my macbook back from Heasync Logic board and now...

    I just got my macbook back after 11 days (and i have procare). I brought it in to apple to get fixed because i, like the rest of the macbook using population, was suffering from the random shutdowns... well, i picked it up today... the machine was screaming (as in good) it passed the AHT with flying colors before i left the store... well, i just got home and performed the QT and iTunes updates that i missed while it was at depot and after the required restart... a beautiful stream of colorful lines started dripping down my screen (its the logic board i know) I am not questioning what my current problem is... what my question to all of you who have received your macbooks back after having the MLB and Heatsink replaced....
    How many of you have had your NEW logic boards go within a couple days of getting your machine back?

    how does one reset the resolution?
    system preferences>displays>Display tab
    choose an alternate resolution, and then reset it back to the original, and restart the computer
    i mention this because apparantly its a flaw in the logic board that is fixed by doing this, its helped others out (search a couple pages deep and youll find more talk about the lines on the screen)

    Restore, if iTunes will let you.  Everything except the password will be restored.  Connect via cable to the computer that you use for sync.  Be forewarned that it takes a long time.  From iTunes, select the iPad/iPod and then select the Summary tab.  Follow directions for Restore and be sure to say "yes" to the backup.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.  Again, say "yes."
    At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod.  As before, say "yes."  Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time.  If that happens, only the apps that are part of the IOS will appear on your device.  Corrective action is simple -  choose manual "Sync" from the bottom right of iTunes.
    If you're unable to do the Restore and you have IOS-6 or lower, go into Recovery Mode per the instructions here.  If you have IOS-7, read this.

  • Have just got my iphone back from my daughters who has been using it. I have put my sim card in and cannot update it or do anything as it is stating emergency calls only. it only recognises on itunes as her iphone what should i do please

    i have just got my 3gs back from my daughter and i have put my sim card in and it comes up as emergency calls only. That is my first problem then when i plug it into itunes it only recognises it as her iphone can anyone help my please ?

    I agree with wjosten. Sounds like a sim card issue. Was your sim card removed from a working,activated phone? I've switched sim cards in an iphone multilple times and never had a problem. You might try removing the sim card and reinstalling.

  • Just got my computer back from being fixed and can not load Itunes

    Just got my computer back from being fixed, they took Itunes off. Now trying to download it again and this is what happens, it says thanks for downloading Itunes, but it never launches nor can I find it anywhere on my computer. It doesnt launch when I plug my phone in either. I did notice that it says it downloaded a Binary file? This is on windows XP and Im not good at this kind of thing. Can anyone please help me.

    try downloading a little bit older version of itunes, thats all i got

  • Got my Mac back from Apple Repair... now TimeMachine is messed up!

    I'm hoping this is something "routine" and some of you smart folks can help me out.
    I recently had to send my MacBook Pro to Apple Care for repair (a whole other story! The LCD died...), when I got it back I noticed a couple of strange things:
    1. my iTunes told me I had to authorize my "new" computer (no problem. I can deal with this, it doesn't impact my work. It's just a bit odd.)
    2. my Time Machine backups stopped working. (This is a much bigger problem, since now I'm working without backups).
    Here's the situation:
    Time Machine preferences shows me my regular backup destination drive (it's called "total-backup" by the way, and it's a big ol' Firewire drive.)
    It says "Oldest Backup: --".. as in NO oldest backup. But when I look at the drive out in the finder, there's a folder there sure enough named "Backups.backupdb" which takes up many GB.
    That folder now contains two subfolders:
    - one is called "My Computer" , which itself contains many folders named with dates. This appears to be my old backups folder.
    - the other is called "My Computer 2" and it contains only an odd 8 KB thing named "2008-04-26-182146.inProgress" which contains the date I got my computer back! (And also shows you how long I've been working without backup!)
    Here are my two questions:
    - How do I point Time Machine to the correct backup set?
    - And is it okay for me to just manually delete that "My Computer 2" folder off the backup drive?

    In all likelihood, your logic board was replaced during the repair. There's a MAC address (Media Access Control) embedded in every networkable device that gives a unique ID to every device; the Mac's MAC (name similarity only coincidental) address is on the logic board.
    iTunes authorization is keyed to the MAC address; so are your Time Machine backup files.
    You can't change the MAC address, since it's hardware, but you can change the record of the MAC address in the Time Machine files so they'll be recognized by what it thinks is a new computer. It take Terminal (and guts).. the info is here: http://www.macosxhints.com/article.php?story=20080128003716101
    I don't think that article says to back up your Time Machine files before you start mucking about with them, but that might be a good idea. You may have room for a zipped duplicate right on the backup drive, so that'd be a good thing to do first.

  • Just got my Nano back from service and.....

    I just sent my 2Gb Nano into Apple care and got it serviced. I just got it back and got a completely new Nano. My problem is that this one has a white screen and I havent dropped in or done anything, except plug it into my computer and install it on my computer. I was wondering if I had to send it back in again. Thanks.

    From what I was told by one of the forum Mods a while back, Apple engineers have determined that this is caused by not allowing the firmware update to finish the installation before disconnecting the iPod. Try these steps.
    Reset the iPod.
    If the reset doesn't help, then put the iPod into forced disk mode.
    How to put the iPod into disk mode.
    Now connect the iPod to the computer. This step may immediately take you to the iPod's normal display screen. Reset the iPod to exit disk mode.
    If you still have the white screen, then you should use the updater to restore the iPod.
    Wait until the restore has finished before disconnecting the iPod. If you're unsure, wait at least 20 minutes (it's probably overkill but best to be sure). In my experience, the software updater for version 1.1.1 (and later) takes longer to complete the process than previous updaters.
    That should cure the issue.
    If however it doesn't, and your iPod is still non responsive (doesn't reset, nothing on the screen or button presses don't work), then it will have to be sent away for service.
    See: iPod service request.

  • Just got my iPod back from service...now what???

    I was forced to send my iPod in to be serviced, due to the Folder/Exclamation Point Error.
    I just got it back today. Now what? How can I make this iPod, which is not my old one, but a completely new iPOd, work with my iTunes?
    All I really want are the songs I have on my computer to be loaded on to my iPod. Anyone know what I need to do?

    Welcome to Apple Discussions, Sam.
    Assuming you have a good connection you simply download and run the latest firmware updater from this site. Retore the iPod (which will format it for your PC) and then completely resync it with iTunes and you're good to go.

  • Just got my MBP back from repair and VERY confused...

    Good Afternoon,
    Well, I just picked up my beloved MBP 2.2GHZ SR / 128MB Video Ram 8600GT from repair after a LCD / Logic board / Top case replacement under warranty.
    When I powered it up to test things, I went to System Information and my Mac stated it was a 2.6GHz SR / 256MB Video Ram 8600GT / 800Mhz FSB.
    Am I just really confused or did I get a serious upgrade wih this repair?
    Thanks in advance!
    DebtManWalking

    maybe it was cheaper for apple to replace with an equivalent/better model than fix the old one, the warranty terms allow for this

  • I just got my computer back from Apple - They fixed nothing

    Long ago I made a post expressing concerns that none of the animations on my computer were as smooth as my girlfriend's Macbook with the same specs. I tried everything recommended to me, including typing some stuff into the console. Nothing fixed it.
    In order to make sure I wasn't just crazy, I downloaded Xbench, a program recommended to me for benchmarking. I was told that my score should be around 100.
    That being said, my score does not get above 70. Clearly something is wrong with the graphics processing on my computer because when running to through the graphic benchmarking portion of the test, my girlfriend's computer speeds through it, whereas mine goes fairly slow.
    After being completely stumped by the problem, I took my computer to the Apple store nearby to get repaired. The Mac Genius didn't seem to believe that anything was wrong (he refused to acknowledge the benchmarking program) and said he'd have my logic board replaced anyway.
    I just recieved my computer today and nothing has changed. I'm still getting low scores on Xbench and none of my animations are as smooth as they should be. What the heck is going on? Is it possible that nothing was actually replaced, or could the problem be stemming from something that isn't on the logic board? A RAM diagnostic didn't turn up anything...

    A computer's performance is affected by software or else hardware issues. If the memory chip isn't 'seated' right, hard drive speed or read capacity, whatever. Could be anything. In regards to software, there can be installation issues - people say that a fresh install with all-at-once updating has less problems than an install where you upgrade or "add" to another install. Same goes for updating after you add software applications - it is just more complex and less efficient. But there are so MANY ways to tune a computer. What about energy saving settings (vs "performance")? Also the more ikons you have on your desktop the more RAM is used. It is a learning curve you can begin by opening Activity Monitor. You want to watch how much RAM is used, disk activity, startup activities running in the background (display saver on or off?) and so on. CPU activity (and temperature) is a big indicator.
    If you are hoping to someone here to post "one thing" that points to your concern, I doubt that will happen. Sometimes hardware is manufactured 2nd rate (the Seagate Drive issue from months back) and you MIGHT have a poor quality part in your machine. Not often though. Diagnosis takes time and patience. If you are in a hurry take heart in the fact that Macs have a great resell value and get rid of it / buy fresh, upgrade to the Santa Rosa - better video. (Or offer money & a trade for your GFs - maybe speed isn't as important to her).
    If it were me I would try a fresh (erase) install & download all the updates at once. This is recommended by posters here. It is often posted that a new software update 'slows' a machine from prior to the update. I don't have an answer for why, except that the times I downloaded all-in-one updates I had less slowdown problems. It is a pain, though. And it may not 'fix' things. That's the reality of performance trouble-shooting, though. It's real life & it ain't fair.
    Another way to go is to upgrade the performance through a new hard drive (7200 RPM).
    Another thing to try is Opera / Firefox. I find Safari inconsistent - sometimes fast, next day slow. Opera and Firefox can really fly in comparison.
    You are right to be annoyed. The logic of the situation is that a mass-manufactured unit should be measurably consistent (and it obviously isn't). The sad part is that these things can take so much effort to determine, it may not be worth your while to find out 'why'.

  • Just got my mac back from apple, airport card MIA

    2 weeks ago the hard disk drive was acting funny and after attempts at repairing and reformatting apple decided the hardware had failed. After a long 2 weeks without my iMac I finally get it back with a fresh format, when I boot it up I don't seem to have the option of connecting to the internet wirelessly via my airport card.
    I have also noticed a few other things, such as when I hold left control and mousewheel up to zoom in on the screen the frames per second drops DRASTICALLY, it didn't do this before. and for some reason "photo booth" is just a question mark on my dock and when I click it nothing happens.
    Photographic evidence within:
    http://img205.imageshack.us/img205/2637/cimg0202bh8.jpg
    Is it time to take my imac back to apple for another 2 weeks?

    I went ahead and installed 10.5 as I had nothing else really going for me. And for the most part this seemed to clear ALL of my problems.
    The only problem I am having now is that whenever I restart I must manually go into the internet options and select my wireless network from a list.

  • I got my macbook back from apple store and now it wont start

    I took my macbook to the Apple store to get keyboard replaced. Now, I can't get it to boot up past the Apple screen with the spinning dial beneath it. I there anything I can do at home or should I take it back? More importantly, is this a fix I'm going to have to pay for because my computer is no longer covered by warranty?

    HI. Try botting up your Macbook using the install disk (insert the install disc and press C). On the menu bar, click on disk utility and try repairing the disk and disk permissions.
