Macbook shutdown problems

Just got my macbook and have been using it for about a week. It has been working just fine until recently where for some reason the jarring noise at start up won't actually sound, and when I attempt to shut down the computer...it just shows the background and my cursor, but doesn't actually shutdown. I have to hold down the power button to actually turn it off.
any help is awesome
peace out

Hey VooDoo -
Welcome to the forum and sorry that you're having problems.
Are you giving your MacBook time to shutdown. Sometimes it may take longer because of items running at the time.
Some common methods of shutting down are hitting the Apple in the upper lft and selecting Shutdown from the dropdown menu. Another is to press the Start button (not for a long time like you mentioned for a forced shutdown but more like when you turn your MacBook on) and a menu comes up to select from. The enter/return key selects the highlighted item (shutdown) so, the action is Startbutton - Enter (i like this way)
If the problem lasts beyond waiting longer or improving/revising your method, I'd take it up with Apple because you may have a hardware problem.
Hope this helps.

MacBook shutdown problem

My friends MacBook will not shutdown if he closes the lid. He first tells the computer to shutdown, then if he closes the lid it will keep running till it exhausts the battery. Is there some perferance for this?

I'm not a Genius but in both my jobs I perform some of the same functions of the Genius. (I teach IT and I work part time for an Apple reseller.) My take here on the board is different from lots of peoples' because I can see so many sides of the issue. I've been an angry customer (white spots on my 15" alBook display and 2 dead logic boards on an iBook). I've been the stumped techy who gave the user some canned advice hoping it would work whilst filing the problem away in my "Hope this one gets a definitive answer soon box." And I've been the retailer who seriously suspects the computer user has abused his machine. And I've seen that Apple generally gets it right in the end, even though it sometimes takes longer than I'd like.
I came across this shut down problem here on the discussion group sometime last week through a post where the user complained that his MacBook spontaneously started up while in his bag and he found it burning hot hours later. I didn't post anything because I had nothing constructive to say but to be completely honest about it, my first assumption was user error.
Then suddenly I was reading lots of 'my computer doesn't shut down right' and 'my computer doesn't stay shut down' posts. Now my attention was grabbed and naturally the first thing I did try shutting mine down. No problem. I asked my boss and the head tech (they both bought MacBooks) and both of them could shut down okay. So now I'm no longer thinking it is user error but I'm stumped as to what's going on. Then I read the post that put it all in place. The user indicated that her computer's shutdown was messed up if she shut the lid. Now I had something to test...mine shut down. Darn! But I took that information to the shop with me and Ken was able to reproduce it very reliably on his MacBook. But the boss couldn't at all and I can't reliably. But other than this, Ken's computer is fine and so is mine.
So from my point of view we have to give the Genius the benefit of the doubt. I was a believer last week - I was certain a problem existed but I didn't know what was going on. By the end of the week I knew how it could be caused and was pretty certain I'd found two reliable work arounds. But we don't have any clue as to the root cause. As of Monday there was no word from Apple on the matter. The fastest I've ever gotten a repair box from Apple is 2 business days and with the holiday l-o-n-g weekend I wouldn't get antsy until Thursday.
Are you right to be upset? Heck yes, you paid some serious money expecting to get a good computer. But it is a complex piece of equipment and no matter how hard and reliably you test issues turn up once it reaches the consumer. If we had no reliable work around I'd be upset but at present I put this issue in the annoying but can live with it for now box. Now if I had a MacBook that mooed it would be an entire different herd of cattle!

Yes, Apple acknowledges the problem but it does not make consolation for its customers. How?
No.1: they are requiring 2 weeks before returing you the unit after service. - IT disrupt WORK and entirely damage the customer's life. It's not what I wanted when I bought the unit.
No.2: They do not offer a temporary replacement to fill in.
No.3: They do not give anything but the WORD sorry... WELL, ITS NOT OK and I cannot forgive. I hope you get my point and understand my sentiments.
I CANNOT say thank you apple.

Random shutdown problem on G5 dual 2.3 GHz w/OS 10.4.7

Hello,
I’m using a dual 2.3 GHz G5, and it’s been working flawlessly since I bought it about a year ago. Until yesterday, I was running OS 10.4.5. Yesterday I upgraded to 10.4.7, and as soon as I booted up after the install, I started having a maddening problem with my computer randomly shutting down. (Not sleeping, but a complete power down.)
At first, the shutdown would happen immediately after powering up; my computer wouldn’t even make it to the blue progress bar. I zapped the PRAM and tried something I found online about unplugging the computer for 15 seconds, then plugging it back in. It now boots up, and I can log in, but the computer still shuts down randomly.
There seems to be no pattern to the shutdowns. I tried taxing the processor by opening and resampling huge Photoshop files while lots of other apps were open, and things were fine. Then it would conk out while I was composing an email.
I’ve heard of this random shutdown problem affecting Macbooks, but I have yet to find anything about G5 towers and OS 10.4.7. Does anyone have any info/advice?
Many thanks.

G5 dual 2.3 GHz Mac OS X (10.4.7) 2.5 GB RAM, 250 GB HD

Thanks for the advice. I did check the system.log in Console and found the following altert:
PMU FORCED SHUTDOWN, CAUSE = -122
Now, since my computer is just over a year old, and since this problem happened immediately after applying the 10.4.7 OS update, I found it hard to believe that my hardware could be responsible. After 2 days of troubleshooting, I was stumped; after a 2-hour service call, so was Apple tech support. I ended up doing an archive and install back down to 10.4.5, and all is well.
I tested this issue on other machines running 10.4.7 and had no problems. It seems that the following specific combination of elements triggered the problem:
• PowerMac G5 dual 2.3 GHz (dual 1.8 machines did not exhibit the same problem)
• OS 10.4.7
• Logging in with Open Directory/Active Directory mobile profiles
• iTunes 7
Bottom line: if you’re using a dual 2.3 GHz PowerMac with mobile OD/AD profiles, do not update to 10.4.7, and steer clear of iTunes 7, at least until there is a patch update available.
(And Apple wants to be taken seriously in the enterprise market?)

Are the replacement Heatsinks fixing people's Random Shutdown problems?

Is the replacement heatsink (the shorter one) still the method of choice from Apple for fixing Random Shutdown problems?
Is it working for people who've had it done recently?

Does this max out the CPU?
Yes. People who advocate this are testing to see if it's possible to induce a "random" shut down.
Why would anyone want to do that?
Good question. I've seen two reasons put forward: (a) It's better to make it happen now yourself rather let it strike out of the blue at some later date (and if running this test doesn't induce RSDs you can feel confident that your computer is probably immune); (b) If you take your MacBook to an Apple Store it could be useful for demonstrating to an Apple "genius" that your computer has the problem, especially if your shutdowns are infrequent.
(personally, I don't agree with (a))

Macbook Shutdown Solved

http://iith096.blogspot.com/2006/09/random-macbook-shutdowns-solved-at.html

for me, the problem began RIGHT AFTER the SMC Firware Update was installed.
http://www.apple.com/support/downloads/macbooksmcfirmwareupdate.html
man oh man, I wish i could uninstall it!!! i never cared about the temperature issues, and now i've got really loud fan noise all the time and the computer shuts down randomly.
well, almost randomly: it seems to do it only after i wake it from sleep. maybe after an initial startup, too. what makes it go away is when i HOLD DOWN the POWER button for a long time when starting it up from a random shutdown. then i get a LOUD beep, and it starts and runs fine (till it sleeps again) but the fan noise is ridiculous.
please let me uninstall it, apple....

Random Shutdown Problem Fixed (for now)

I experienced the same random shutdown problems/symptoms with my MacBook that have been extensively described in this forum and elsewhere. I sent it back for repair under AppleCare and it was returned in 3 days. It has been running now for 4 days with no problems and far cooler and quieter (the fan rarely comes on) than it was before. The repair sheet indicates that the heat sink and heat assembly unit were replaced.
I'll keep my fingers crossed, but at least in my case and perhaps others, the problem may simply have to do with the thermal contact with the heat sink going bad and the processor simply shuts down due to overheating.
MacBook 2 GHz Mac OS X (10.4.7)

Followup:
They told me something interesting at my Mac Retailer. They have had two other machines brought in doing the same thing. They tried new logic boards with no success, they tried new thermal assemblies with no luck, new ram - nothing seemed to solve the problem.
What they finnally did was replace the Hard Drive - they tell me this has fixed the problem. Now I don't know if that is what they'll do to mine. The other two machines had the 60gb drives - mine is a 100gb, but we'll see. From all I have heard, this doesn't make a lot of sense to me. Anyway, we'll see what happens.
Anyone else hear anything about replacing the hard drive?

Macbook Battery Problem

Hi all, this is my first post, but something weird happened to my macbook that I have to share with you.
Ok, my Macbook Core Duo 2.0GHz (1st generation) have had no problem during its first and half year. Then I left the notebook sitting at home for one month as I was away on business. Came back, the machine won't start, used AC adaptor and showed the battery not charging, "x" and everything. My warranty expired, so I bought a new battery. Once I got that, it worked fine for almost 7 months.
Another business trip left my macbook for 1 month, I came back, the battery is dead again!!! So I went to apple support and bought another new battery. This time I installed it at home, and it doesn't charge what-so-ever. I tried everything from SMU reset, PMU reset, P-RAM reset. NOTHING WORKED.
So I took a friend's macbook battery to try, and it worked! I can charge that battery with my macbook, and my battery won't charge on his macbook. So scientifically I thought its the battery defect. I went to Apple Care and they say they will replace it for me, but think that it should be my macbook's problem. Must be the Logic Board, I explained why I disagree, and that the battery came with only one LED blinking when I got home to charge, the current was already too low to charge.
Anyways, I was able to buy a second-hand battery really cheap but with limited life-span and use it until my replacement battery returns. Everything seem fine and I can charge it up to 100% although it will only last me 50-mins, still not bad, right?
I was reluctant to completely drain this battery now since I am afraid it will drop to zero and won't recharge like the other ones.
I am using Boot Camp, and Vista as well as OS X. Suddenly today, two days after I bought the 2nd hand battery, I was using Vista to show my friend the battery problem is fixed. But suddenly out of nowhere the battery dropped from 95% charged to 0% in seconds. It shuts down automatically, and the battery was flashing one LED indicating it's dying.
I started back in Mac OS X and found the charger able to recharge, but it fixed at 0% for 20 minutes. I thought I am screwed and went out for a smoke. I came back to see the battery charging back to 5% and then slowly to 10%, and 20%, suddenly it went back to 85% in seconds, and then 100%. I try to unplug it and it seemed fine. I left it on without the adapter for 20 minutes, the battery drain normally, to 70% (it's fine considering the battery was 2nd hand) My friend thought I should try to switch back to Vista to see if the same thing will occur. So I did, and before the Vista screen came up, the macbook blacked out. I checked the battery indicator and it's flashing one LED again!!!
So I switched back to Mac side and re-do the charging, this time it took longer to get back to +90%, I thought this is normal, 'cause I did use the battery longer on the Mac side before switching to Vista for the test.
I thought to myself, why Vista drained my battery, and then I remember the first battery that died on me was about the time I switched the PC side to Vista. Prior to that, the PC side was using XP. The second time it died it was in Vista as well. I also remember I wanted to reduce the size of my PC partition, so I trimmed off unnecessary features like hibernation by (Powercfg -h off). It saved 2G in size but it may be causing some problem to the charging circuit for the Mac-hardware??? Don't know for sure.
So I erased my Vista partition, and re-installed XP. Since then I tried both sides without adaptor, usually for 10-minutes or less, and no sudden dropped to 0% occurred since.
Everything else is working fine with my macbook, except the power features. Right now at least I can charge the battery, but I am always worried about when or IF the battery will dropped off and kill itself.
I am waiting for the replacement battery to return from APPLE, and hopefully when it returns, my Macbook will be able to recognize the DEFAULT low-charge of a new battery. I'm still not sure if my macbook is defective, and if it did killed the first battery replacement they gave me a few days ago. If it did kill a decent battery, will it kill this new replacement as well??
I know for a fact that the reason why the machine won't charge the battery is because the current of the battery has become too low for the machine to be able to charge it. If the current becomes lower, the "X" will occur suggesting that the machine doesn't even recognize it's a battery. But what I want to know is what caused the battery to drop to such a low current if I turned off the macbook during storage.
Sorry for the length of this post, but I have to be clear on all the details if I want help, I suppose. Right now my question is (1) Why is this occuring?? (2) Am I right in assuming that by removing Vista with XP, the problem will not repeat?? (3) Is it likely for any new or 2nd hand functioning battery to drop to the state of the other battery any time soon?? (4) Am I doing proper care for my Macbook, and what should I do in the future to avoid the same problem from occuring??

gpotts,
Thanks again, here's my battery profile: (keep in mind this is the 2nd hand battery I am profiling) BTW, something happened when I was doing this message, I left the notebook on for about 20 minutes, it dropped from +90% to 48%, macbook prompted me that the battery is running low. I plugged the adaptor and it went back to +95% within minutes...
Good thing is, I haven't seen the sudden drop to 0% ever since I removed Vista, and also I am able to charge my battery everytime I try now, no more "NOT CHARGING" or "X" indication.
Any clues??? Thanks in advance.

Clock problem and shutdown problem! Are they related?

Having a problem with my Dual 2 GHz Power Mac G5
A few days ago I noticed that my clock was not showing in the menu bar in the upper right corner of my desktop.
I went into System Preferences and went to Date & Time. Under the clock tab “Show Date and Time in Menu Bar” the box was not checked off. I checked it off and went to the “Date and Time” tab. The date and time was correct. I then checked the box “Click the lock to prevent further changes” to lock it. The date and time did not show up in the menu bar. I then went back to the tab “Show Date and Time in Menu Bar” and the box I checked was not checked off even thought the lock was still locked.
I then moved my cursor up to the menu bar in the upper right corner to see what would happen and the spinning beach ball started up but only for the original icons such as Bluetooth, Mobile Me (which I do not use), Time Machine, Spaces (doesn’t indicated the number when I switch Spaces, etc. The icons Norton Anti Virus and Tech Tool Pro in the menu bar are okay.
Also, when I attempt to shut down my computer the system clears the icons from my desktop except for a picture I have on my desktop and I get a gray wheel spinning and the system just hangs until I press and hold the on/off switch. I don’t know if the clock and shutdown problems are related.
The only new software I loaded recently was Skype with Logitech WebCam for the Mac and Quicken 2007 (Had a problem with Quicken 2006). They both are working okay.
And ideas on why I cannot get my clock to show up and my computer to shutdown?

You may have to consider a new post in the Hardware forum area for the computer
model and build/year; if there is a possibility of some basis the matter could be in
the machine and not the software running within it.
Your last two/three posts are in the Leopard 10.5(.8) forum area and do indicate
some kind of problem where troubleshooting the computer to discover if the matter
at hand would be either hardware or software based, may be the way to go.
The link to the 10.6 Snow Leopard forum won't be of help if your computer is a
PPC-based G5 tower, or other older pre-Intel configuration. And I remember
your earlier questions about the iMac G4 and some other issues in the past.
You may ask the moderators to put your post in a new thread of its own, in the
Leopard 10.5 area; so as to not 'piggy-back' another topic; even though some
of the odd issues you've had seem similar to this OP's topic line and appear to
be in the same general series of hardware. {The question here seems valid.}
The routine suggestions to check, test, verify, and perhaps repair or replace
the system; save a bootable clone to suitable external standalone device if
testing a suspect computer's viability is recommended; and the basics if not
already tried to help isolate the issue(s) as you've posted elsewhere, may be
of some help to try and do; so in that matter, a new thread of your own is best
for your own directed feedback. Since this kind of advice applies to most any
situation, including troubleshooting what may be hardware or software, I'm
adding my two and three-tenths cents worth here.
Your original included Apple Hardware Test may be of some help, in the process
of elimination; but is not conclusive, so other methods would be also suggested.
Some ideas appear to cover the same ground. However, system corruption or
disc failure can also manifest itself in odd ways & affect things indirectly for a time.

So, at the risk of inadvertently alienating the OP, I am posting this as
a general help to following readers at some later time; and it may not
be too simple for a refresh course.
Some software issues can be resolved by repairing disk permissions,
and re-applying the last OS X update Combo file over the same one
already in the system; or if not up-to-date already, check & repair all
the general items and then apply the last Combo update.
A too-full hard disk drive can compromise the system integrity, so that
is a matter of course to keep up on what resources exist and remain
for the OS X to function correctly and for apps to multi-task together.
However that works out...
Good luck & happy computing!

Macbook airport problems linked to battery power?

I too have experienced the macbook/airport problem, specifically since 10.5.8 came back. When I upgraded to 10.5.8, it was so useless that I just reinstalled tiger. Then Snow leopard came out and I upgraded only to experience the same problem but not as severe.
I have just been able to pin/point the problem today (mainly because I just grew so frustrated and spent considerable time trying to figure out). I have tried all the other potential fixes posted on here to no avail (changes airport settings, replacing card, changing dynamic IP to manual, encryption etc).
This is what I have determined and was able to reproduce it:
When macbook is running on power (plugged in):
If battery power is below 60%, connection is spotty - the lower it is, the worst the problem.
If the battery power is above 60%, no problems at all, runs fast and no drops.
When macbook power is not plugged in and running on battery:
Below 60% almost useless
Above 60% spotty and worse as the battery drains
Can anyone else test this out? I've sent Apple an e-mail.

I've gone down to maybe 15% without any noticable difference in connection.

Late 2013 13"MBP-Shutdown Problem

I was having shutdown problems with my Late 2013 MBP 13"-the MBP would go to the gray screen and the small pinwheel would progress to different hash marks every 3-5 seconds, the machine would not shutdown at all, it was stalled, so I called Apple and we trouble shot. During our troubleshooting adventure it dawned on me that the problem could be related to my Antivirus Software-Intego. So I went ahead and disabled the real-time scanner and...viola, it shutdown with no problem. So I am letting people know that as of currently, Intego's real time scanner could cause issues during shutdown. I placed it on a scheduled scan and placed everything else on; no issues now.
So my only question would be; I have the same antivirus software on my early 2012 15" MBP with no issues. Though, I do remember having very slow shutdowns for sometime and then it seemed to resolve itself. The major difference in these two machines appears to be, besides the retina displays, the mechanical HDD vs SSD. My 15" (early 2012) has two Mech. HDD while the new 13" has of course SSD. I am thinking the antivirus software isn't handling the SSD appropriately.
Any-how, I just wanted to give a quick (though detailed) heads up.

OK, I messed around with this issue over the weekend. Here's what I did:
1. Used iPad 3 until I have run battery down to about 50%
2. Plug in to left USB port on Late 2013 rMBP. Battery icon starts displaying "flip-flop" behavior.
3. Replug into right side USB....no problem, all behaving well.
4. Tried plugging in my iPhone 4s into same cable on left USB port, no problem.
5. Replug iPhone into right side USB....again no problem, all behaving well.
Here's where it got interesting:
6. Exchange charging cable for a newer cable with the smaller-sized 30-pin dock connector.
7. Plug iPad into left USB port...and viola! Battery charging icon is steady...no "flip-flop"!
8. Replug into right side USB....no problem there either, all seems normal.
I have no idea what's going on, but this seemed to have solved prolem. BTW, the older cable, when plugged into wall charger, charges the iPad just fine.
Hope this helps someone else with this problem.

Shutdown problems

I tried updating to 10.5.6 this evening (I should have read these forums first to be forewarned...but anyway..). I was prompted to restart and ever since I have had difficulty shutting down. All icons, the dock, desktop and menu bars switch off (as usual) and the screen goes to blue and just sits there. The HD is spinning and the screen goes from a light blue to a slightly darker shade of that blue and the cursor shows up on the screen as well. But the computer just doesn't shut down.
Is there a way to force shutdown (other than holding the power button down)??
Also, what can I do to help fix the problem.

I ran disk utility and no apparent problems came up.
I then went hunting in other threads for clues and found a link to the Apple download updates page which gave me an idea.....
Since my shutdown problems started when I was prompted to restart for the 10.5.6 update I thought to re-install the 10.5.5 update.
This seems to have worked. No idea why 10.5.6 would lock up the shutdown process but at least I get a clean shutdown now.
Anyone have a similar issue??

Need more info - same spontaneous shutdown problem...

I'm using a very trustworthy 2.5 year-old T500 running Vista SP2 32-bit and my laptop has begun to have the same spontaneous shutdown problems as other users who've written here. I suspect it's overheating. I normally use my T500 on a docking station, which may or may not exacerbate an overheating issue.
I want to address this problem to ensure that I can continue to progress on my PhD dissertation (!) without crises, so I have taken some of the steps previously recommended for this problem here on this board. I installed TPFC today to begin monitoring CPU temperature and it appears that it runs between 55 and 65 C. Other temps listed are lower. I also made necessary adjustments in Power Settings to maximize fan speed and allow CPU speed to float. I also removed the battery so I'm using AC power with no battery/recharging processes to add to the problem, though I'm not certain that last part will make any difference.
I want to also clean the fan since I'm sure it's probably dirty after 2.5 years of continous use in my house. How can I take my laptop apart to clean the cooling fan? Or is this something I should take it to a repair shop to accomplish?
Thanks in advance for your advice.

No, my machine is not under warranty any longer. I agree, if it was, there's no way I'd risk voiding it by tearing it apart myself.
Thanks for causing me to double check. I DO have a few months of warranty left, so this baby is going to a professional! I could probalby do it myself, but why risk it?
