MacBook Core 2 Duo reboots upon sleep (closing lid)

I've had my new MacBook for over a month. Recently it began restarting when the screen is closed. Very annoying problem. There is no warning, my entire system just reboots. Seems like this only occurred after 10.4.9.
If anyone else is having this problem, please let me know.

Same thing here... When I close the lid the apple on the cover flash and then I ear the booting cheer, if I open the lid and I see the start screen. It happen to me about 20-25 times and only since about a month (with a c2d macbook, 7 months old).
Hope Apple will fix this. I don't want to send it in for repair cause it really seems like a software glitch.

MacBook Pro Core 2 Duo reboots after I close lid

I have a MacBook Pro 15" Core 2 Duo 2.33 GHz running Mac OS X Tiger 10.4.9. It's about 6 months old. For the last couple of months, I've noticed that every once in a while, when I close the lid, moments later I hear the reboot chime. If I reopen the lid, I see the machine booting up. Any unsaved work is lost. It happens maybe once every week or two and I do not know how to reproduce the behavior.
A little googling shows that I'm not alone; others have experienced this problem. See

and
http://www.apple-discuss.com/viewthread.php?tid=382
I haven't seen any threads discussing this problem here on Apple's discussion board. Is the problem acknowledged by Apple? Is any fix known? Should I take my laptop in for service? Will Apple help me if the problem is not reproducible?
Thanks for any advice you can offer.
MacBook Pro Mac OS X (10.4.8)

I've had this happen about 3 times in the 3 weeks i've had the computer. This morning when it happened, i lost about an hour's worth of typing in MacJournal. You don't need to save in MacJournal, it saves everything if you set it too, like Sticky notes. Unless the computer crashes apparently. Due to this happening, i ended up finding a great keystroke recording backup program called BackTrack, but i digress.
Now that you mention it, i will have to pay attention to whether it's always plugged in to the power adapter when it does this, because something i've noticed several times, though intermittently, is that sometimes when the power adapter gets pulled on, or comes loose, the display dims a little. That's never happened on any of my other previous 3 laptops. I CAN reproduce that, i did reproduce it when it happened tonight, though it doesn't always happen. But the dimming may be a sign that the computer wants to go to sleep or temporarily shut off. I know there are some serious problems reported with the (otherwise very cool) magsafe adapters--I read so many reports of adapters that suddenly after several months of normal use, would spark, disintegrate at the junction wiht the computer, become hot and melt, and other things of that nature. If you look up the magsafe adapter in the apple store and read the user reviews, more than half report such problems.
So maybe this is related to the random spontaneous reboots. I've never had a computer do this before either. Has anyone noticed if there's any pattern in terms of it being plugged in or not?
Here's another thread about the issue:

MBP Core 2 Duo randomly restarts when closing lid

Randomly my 2.33 Core 2 Duo restarts when closing the lid instead of going to sleep.
A real pain when your in the middle of something
Anyone know a fix ?
Recently had a new logic board (due to faulty graphics card) and hoped this might also cure the restart at sleep problem. Did not.
Advice welcome.
Thanks

I would suggest you to reset the power manager to check whether the issue resolves. If the issue persists please contact Apple Authorized Service provider for further troubleshooting.
In this case I suspect the logic board or may be the sensors as a issue but to confirm it is always good to contact an AASP for further troubleshooting.
To reset the Power manager refer this article http://docs.info.apple.com/article.html?artnum=303319

Why does my Macbook Core 2 Duo 13" keep shutting itself off and/or repetively rebooting on its own?

My Macbook Core 2 Duo 13" won't stay on for any significant time anymore. When it does, it seems that the slightest movement, or pressing a key will shut it down or it just shuts down on its own. Or it reboots repetitively after chiming. Or it remains on as it is doing now for the last 30 minutes, long enough to see if it needed a firmware update. It's never on long enough to really use it anymore.
When there is no image on the screen, I often can hear the fan or drive running quietly in the background. I can turn it off by powering down with the button. Without the power cord, it will eventually drain the battery if I don't force shut it down.
I have verified that the hard drive is OK by removing it and mounting it externally.
I have been unable to do a hard system reboot (hold down powerbutton until system starts and continue to hold until tone) - no tone, just keeps rebooting.
When it stayed on long enough, I tried to install the firmware 1.1 update. Message was that it didn't need it.
I have tried removing one RAM card at a time ( it has 1GB + 512Mb). Haven't really noticed any change. "POST" message is OK when it starts
Any ideas? I've looked at all the "usual suspects". Thanks!

My MacBook Core 2 Duo will not boot up. In safe mode I see keychain problems and Mach 1102.

My MacBook Core 2 Duo will not boot up. In safe mode I see keychain problems and Mach 1102 and it keeps circling through the same error. Also the screen is so faint (pressing the F1 and F2 keys don't do anything). I got this from a friend and he didn't have any of the original discs. Any suggestions? From what I've read it's a problem with a recent update. I've never had a Mac so I'm trying to learn and fix it.

I just had an issue like this. I was able to boot up with an external firewire drive, although it was a lot of trouble. I think doing an option boot finally worked; holding down the option key, I eventually got to see the firewire drive was bootable, and booted from it.
I put the thing in verbose boot mode (command - v , I think; but please look it up. I have no Mac books at work to check). In verbose mode, you could see that the hard drive could not mount; the OS tried to do fsck, but it failed around 2/3 of the way, and the CPU was halted.
I was occasionally able to boot normally, but never in safe or single user modes; these do a disk test first, which invariably failed.
I could see from the system and console logs when I managed to get the firewire boot going that there were repeated errors trying to access drive s03, the internal SATA drive. The logs on the SATA drive showed huges numbers of errors. At a wild guess, for some reason a lot of sectors went bad all at once. There had been a some erratic behavior before, but I'd put that down to the single processor G5 problems. (these were non video related, just freezes).
Applecare wanted me to carry the huge thing into the local Apple store, but I persuaded them to just send me a replacment hard drive, which they did. The new one works perfectly.

Macbook Core 2 Duo screen glitch/flickering??

My late 2009 macbook has a bad screen glitching issue anytime you move the screen. Sometimes I even have to hold my screen in a certain place for it stop from glitching so i can use my computer.
If I took my computer to the apple store for a repair.. how much do you think it would cost?

Macbook core 2 duo ti tac noise under keyborad

Hi!
I have a new macbook core 2 duo 2 gh. There is a soft tic tac noise under the keyboard. Is this normal? Where does it come from?
Thanks,
ENRIQUE.

Ola Jenriquegp,
Never heard one on my macbook especially under the E key.
First I thought if was HD clicking sound but the HD is located under your left hand palm rest area, so it must not HD.
Maybe it is the fan sound when it start to kick in or slow down.
If that clicking sound is obvious and you are not comfortable with it, bring that to apple store or authorized apple service center and let them check that for you.

Macbook Core 2 Duo keyboard connector

I have a bad macbook Core 2 Duo keyboard cable ribbon. Does anyone have some extras for sale or know where I can buy some? I don't want to buy the whole keyboard.

*"Anyone that works at a certified apple repair or non-certified center can get this cable ribbon. "*
Well then it seems like you already know where to get one, so why are you asking here when you already know you can call a service center?

Macbook Core 2 Duo Excel 2008 Not Responding

I have a Macbook Core 2 duo with Snow Leopard. I have Microsoft Office 2008 and recently my computer is running slow, but now excel will not load at all. It shows the color wheel and then the "application does not respond". What should I do

Thanks for all the helpful answers. I mainly use the Korg legacy collection synths, and a variety of Waves plugins, and my current macbook can run quite a few instances of the synths and plugins, so I guess based on the information given the base mac mini should be able to handle my projects ok. As has been mentioned, I guess the best thing to do is to try it.
Thanks again,

Macbook Core 2 Duo speaker balance

Hi,
I just got a Macbook Core 2 Duo 2.0 Ghz.
I have read about speaker volume and distortion problems which I don't seem to be having. But it sounds to me that the sound coming from the right speaker is louder and clearer than from the left? Has anyone experienced this? It's not very bad, but it is noticable. Should I send the MacBook to repair for this?
Thanks!
Danny

Yes, I noticed the same thing. I just bought my MacBook a couple days ago. I was playing around with iTunes last night and noticed I wasn't getting as much left channel as I wanted from the built-in speakers.
Went to sound prefs and changed the balance but could never really hear it get past center when I moved the slider all the way to the left.
Thanks to you guys pointing me to the MIDI utility I was able to use the speaker set up there to listen to each channel. And you're absolutely right, left channel sounds like it's coming from center.
If all MacBooks sound this way, I guess there's nothing that can be done about it. At least I didn't have to spend any time going to the Apple Store and have it explained to me hehe.

DDR II 800MHz in Macbook Core 2 Duo

Hi!
I've go Macbook Core 2 Duo with 1Gb of DDR 667MHz RAM. I want to upgrade RAM to 4Gb, but I can't find any RAM with 667MHZ (5300) speed, only 800 MHz (6400) modules are available. Will this work in Macbook?
P.S. I have PC based on the same CPU and Chipset and it works well with 800MHz modules, it just slows down memory speed to 667MHz.

Check out OWC 667Mhz RAM

You should check the specific MacBook model you have and use that to select the correct memory.

Macbook Core 2 duo - lion install problems.

I picked up a used white Macbook Core 2 Duo (2007) recently. The person I purchased it from installed a new 60GB SSD drive and 4GB of ram and put Lion on the machine. The computer booted fine for the first 4 times, and then on the 5th time it said "Installing OS X" and then said there was an problem with the install???? The computer was working fine before all this happened. Now it won't boot.... BTW I did not do any any updates.
We removed and tested the SSD drive... it appears to be fine.
My other problem is that the person who sold the computer to me did not give me original OS disk... is it possible that the OS he used is corrupted? But then, why would it work fine and then give me the error message after the 5th boot?
Is the problem because I am using an SSD? ... but still makes no sence considering it was running fine before the 5th boot!
Please help, I am looking at purchasing my own copy of Lion and installing it but will this work without having the original Disks?
Thanks!
(P.S. When it did work, the Macbook with the SSD and Lion ran dramatically faster than my 2009 15" Macbook Pro.!)

Thanks everyone for their help... it was another bad disk!
I returned the OCZ HD and replaced it with an Intel SSD... The thing has been running spectacular now! It out performs my Macbook Pro (speed)!
FYI.
I did some digging and on the OCZ forums there has been A LOT of similar complaints regarding the HD failing in the same way mine did... when I took it back for a refund to the store I purchased it from, the tech said that they have been getting a lot of returns on that specific manufactures SSD's... and not just the entry level ones.
Thanks again!

What kind of charger do I need for my macbook core 2 duo 2 ghz.

What kind of charger do I need for my macbook core 2 duo 2 ghz. I just bought one used that didn't come with a charger.

There's 8 different models of MacBooks that are 2.0Ghz. To see which model you have go to the Apple in the upper left corner and select About This Mac, then click on More Info (and then System Report if you’re running 10.7 Lion).When System Profiler comes up check the Model Identifier.
You can get a new power adapter on eBay forabout $20
