Vista - Sleep FINALLY fixed, still annoying Random Shutdowns

Ok, they FINALLY fixed it so the Mac Pro wakes from sleep in Vista RC1 with the recent EFI update, now they need to fix the Random Shutdowns. These occur as if you were telling your system to shutdown, I do not suspect the power supply because it is not an abrupt power loss, it gracefully shuts down, but of-course is annoying as h3ll...
Here's looking forward to the Leopard/Vista releases when all of this should be worked out!
SH
Does Vista RC2 run any better? Have better Bluetooth support?

... well... that was really a (slap in face) help ??
I never tried sleep or hibernate, but I read the latest RTM had some fixes in there regarding better support now for laptops and sleep.
Ignorance is bliss perhaps? or, it is a mixed world? or, there is still software that is not available...
How about, curiosity? that's always been man's greatest strength, too.
Being able to run Windows Vista on Mac Pro must be something even Apple engineers are keep to do and improve on.
Every release for OS X takes a couple updates to be "ready" for use. Long-term that has meant 2-3 updates for the last three+ releases, and each release meant more work for everyone, developer and end user, while "rules" change and hardware and software has to be updated to accommodate those changes. Even good changes are still costly, and some have been costly.
I've lived and survived FIVE releases, $600+ for one machine license, and over a year of that was "1.0" issues all over again. And the same story will get played out next year, too, bet on it.
Some people like to explore linux and alternatives. I have, and while I've never felt linux offered the desktop experience I want, I thought SuSE 6.4 gave OS 8/9 a real run for the money at the time.
Things to Love/Hate about Vista
I can now help my Dad 1200 miles away with his PC Windows w/o needing a PC. I can run multiple VMs. One computer, multiple OSs. VMware, Parallels, CrossOver, as well as native installs.
And maybe, just maybe, a more secure desktop PC will help everyone. However, a really good balanced review might actually be one from ComputerWorld - Vista may make Mac converts of IT folks!
IT folks can support XP/Vista and be running Mac OS X

  • 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))

  • Possible Fix for the Random Shutdown Issue

    One of the readers at MacFixit was able too find a solution to his RSD Macbook. He discovered when he removed the top case (they keyboard) off his machine, the Macbook worked fine. After further investigation, he found out that the top case and the heat sync seem to touch each other while the machine is closed (generating more heat). To fix the RSD he put kapton tape on the top case (to separate the heat sync and the top case) and on the track pad cable. Not only did it fix the RSD problem, another plus it causes the computer to run cooler.
    So it appears what Apple needs to do is, either put Kapton tape on the top case, or move some the thermal grease from the processor too the top case. Another easy fix might be just to send out new top cases (since only a significant minority are effected by this problem, their might just be a set of bad cases out their).
    Before you decide to open up your machine and put on Kapton tape on your machine, keep this in mind, it will void your warranty.

    Macbook   Mac OS X (10.4.7)  

    Holding down the power button until it beeps is still the only way that I can get my machine to boot up fully and become operational. I was starting to think that I was crazy after reading above that all it did was to remind me that my finger was still on the power button. I've had my husband and my son watch this process just to convince myself I wasn't crazy.
    I've been deleting software, going through log files, making other changes to make sure that they weren't interfering with the machine working. I shut the machine off this morning to go do something else. When I turned it on again I forgot to hold the power button until I heard the beep. After I logged in, I realized that I hadn't done that and that the machine had actually gone through the complete boot cycle and login. I thought "wow, maybe I fixed it. Maybe it was something software related." I waited for a few minutes to make sure that everything that it had to do in its start up was finished before I did anything thinking "well maybe its just that I try to do too many things too quickly, and it is operator error and my fault I've been having this problem". Then I went to open Safari and "blink" the machine went dead.
    Then I put my finger on the power button until it beeped to start it up a second time. I've been working on it for six hours now. It's gone to sleep while I've been on the phone, I've woken it up with a short press of the power button and logged in a few times today.....not one single problem in 6 hours.
    It's crazy. I don't know what holding the power button for that long does but it must be resetting or otherwise doing something that causes it to override whatever problem was causing it to just shut down by itself. I love everything else about this MacBook. I don't want to have someone start taking it apart and putting it back together again. If the fix is just remembering to "hold power until it beeps" I"ll live with it.

  • X220 - Random shutdown

    My X220 is running Windows 7 Enterprise Edition 32 bit. I have updated to the 1.21 version of the BIOS.
    I have a 128 GB SSD,
    I am still experiencing random shutdowns under these circumstances:
    1. Only when connected to AC power. I am using 65W standard AC/DC adapter.
    2, Has been connected to the LAN always when it happens
    I have re-configured my computer: Will come back with results.
    1. I did upggrade BIOS to 1.21
    2. I have now reduced the System Performance settiung in Power Manaher from a value of "Maximum Turbo" to "Turbo".
    Kommer tillbaka med findings.

    Grrrr.. while writing this entry - the computer made the random shutdown AGAIN (now using another machine).  Lenovo - can you PLEASE make at least ONE Thinkpad with IBM quality.... 
    Anyway .. here goes...
    Bought an X220 i7 a few months back.
    Data:
    Model:  4291-36G 
    OS:  Windows7 64bit (shipped with unit) + dual booting Ubuntu Linux 10.10 (64bit)
    On BOTH Windows AND Linux these random shutdowns started to happen during the last week - with no change in my usage pattern (software development, browsing, email, etc.  - under both linux and windows).
    The most strange part is that the behavior feels like someone is pushing/holding the power key at random times (anything from 5 to 20 minutes after boot) - because windows goes to "fast sleep" and linux pops up the shutdown/sleep selector when it happens.
    I just updated to the 1.21 bios (using a stand-alone CD from ISO).. luckily it didn't reboot while flashing... 
    This DID NOT FIX THE PROBLEM (I am not sure what bios was there before).
    This really smells like a HW issue.
    NOTE:  Temperature monitors say that the CPU is well under critical - so that doesn't seem to be the issue.
    My guess is:
    1. faulty motherboard (sending the power off event.. or other)
    2. could it be related to the fingerprint reader? - I know it's a long shot - but every time it has been initiated, I think my palms have rested, touching the reader as well as putting a light pressure everywhere else on the palm rest (just trying to help you to troubleshoot the design flaw - it's still a HW issue ;-))
    Lenovo - I have 3 years on-site support on it... how do I get a new unit ASAP (I live in Denmark)?  Can I just move the HDD to the new machine (I remember that Win7 may have some annoying copy protection linking machine, HDD and OS)?
    br
    Lars
    PS Lenovo - as I wrote in the beginning of this post... I have NEVER EVER EVER EVER (well, you get the picture) had ANY problems with this back when ThinkPads were done by IBM. Can you please start making some machines that are as stable as those?  So far, I have been the Proud owner of an X31, T41p, T21 and many more... and *not so proud owner of* T61p and now X220 - both seem pretty flawed - and I seem to remember an IBM internal stating they had to send 1/2 a shipment of T61's back because of serious problems with design, construction, etc...
    PPS I know I was a bit evil above... but still think that premium price should deliver premium product.

  • Problems with random shutdown after replacing a swollen battery

    Hello all,
    Perhaps one of you can help with this issue.
    I'm using a Macbook Pro 17" mid-2007 model. A few months ago, the power disconnected from the machine when the battery had already run down and the machine did a hard shutdown. When I booted it back up there were serious problems with the display. Eventually it stopped working altogether. I took it for service and it was determined to by the NVIDIA graphics processor problem, so Apple replaced my motherboard.
    When I got the machine back from servicing, there was a rattle in the right fan that gradually got worse. After a while the touchpad button stopped depressing in the center. I also experienced several random shutdowns while operating on battery power. I learned about the swelling battery issue with macbooks and ordered a replacement. By the time the replacement battery arrived my original battery was quite swollen. I'm concerned that the swelling battery may have warped the case a bit, leading to the fan noise.
    I have now replaced the battery, but I'm still experiencing random shutdowns after 20+ minutes of use on battery power. I have done the RSS tests that were recommended in other forums and there doesn't seem to be any random shutdown problems when I'm plugged in -- only under battery power. My understanding is that a swelling battery can sometimes cause the battery to disengage from the electrical contacts on the MB, causing a sudden shutdown. I'm wondering why the problem is persisting now with a new battery? After one random shutdown, I tried to power up again using the battery, while pushing the battery into place at various angles, but I couldn't find any angle that would give power to the machine. The fan noise is also still present.
    Can anyone offer an explanation or advise on any methods to overcome these random shutdowns? I have checked the console and the machine isn't registering any error when it shuts down, although when it restarts it says "DirectoryService[35] Improper shutdown detected"

    Yep, it is video (or: or audio for video) so unless you're sure you need it (because you work or will work with the DVC Pro HD video/audio codec), you can remove the plug from its' folder and put it in your documents folder (don't trash it, I have no idea if it is necessary for non-DVC Pro HD users to have it installed too).
    The WWW is littered with posts from people encountering bugs and crashreports with DVCPROHDAudio.plugin as the main suspect. Most of those posts seem to be from video people rather than audio folks.
    http://www.google.nl/search?q=DVCPROHDAudio.plugin&ie=utf-8&oe=utf-8&aq=t&rls=or g.mozilla:en-US:official&client=firefox-a
    But, if you get crashes and you see this one mentioned in the report, disable it, restart, and see if the problem's gone.

  • Do the newer macbooks also suffer random shutdowns?

    Hi there, I'm considering buying a Mac, and I'm stumped for choice. I'm choosing between an iMac 17 inch to replace my PC, or a Macbook for portability. If I am going to be buying a Macbook, I want to know if Apple tested them for random shutdowns first, just so I know that I won't be buying a machine that I'll have to send out within the first week of recieving it. If the new macbooks (as in the ones with Core 2 Duo processors) still suffer random shutdowns I'll probably go for an iMac instead.

    You're claim that everyone who owns 1 (22 out of 25 people) has a problem is total hogwash. Geez, why would you say such a thing? I recently sold my Core Duo BlackBook, one of the first 500 off the assembly line), and never once had a problem with it - ever! I really didn't want to sell it because it was such a fine workhorse but I wanted 801.n on my home network and needed a C2D to get that. I carried it around on all my hospital rounds and it contained every one of my patient's health records. If MacBooks were as you claimed then Jobs must of personally touched my BlackBook with the luck of the Gods!
    Before it was even sold I bought another C2D BlackBook, loaded it with 3Gig of RAM (yes, you CAN upgrade to 3Gig) and the thing is a most excellent machine. Faster, sleeker, and works like a champ. I transferred all my patient's records within 20 minutes.
    My advice: don't believe the naysayers. Especially here. These forums were established to assist MacBook users with all issues, including problems. But the number of problems is miniscule and those you read here come from less than 1% of the MacBook owners.
    The Core Duo BlackBook sold for just $200 less then what I paid for it and it was fully loaded with everything I could put on it when I originally purchased it. I used it a full year (May to May) and figured the $200 was a year's worth of cheap rental.
    BTW, I got a better BlackBook for less money this time around. Faster CPU, larger hard drive, more RAM and a superior laptop to those of my colleagues - what more could a geek physician ask for?

  • Random shutdown then fixed?

    well like alot of other users i got the random shutdown on my macbook the other night. i've been a long time windows user and finally got around to getting myself one of these nice new macbooks just last friday. (my pervious mac being a powerbook 190cs about 9yrs ago now) anyways all was going well till it randomly shut down on me. so i unplugged it and turned it on again this time it took alot less time to just shut itself down without my input. after this it wouldn't even make mac OS so i held the power button for 15 secs and it booted and didn't shut down for the rest of the night (except for when i reset it).
    i had had boot camp installed and while i was in the city today i went into next byte and talked to the guy in there who said that some people had solved it with a software fix. i had a look through these forums and saw that bootcamp didn't seem to play a part in most cases of this happening.
    i ended up deleting bootcamp off the hard drive as i was no longer using it after finding replacements for all bar VS 2005 and Access and was using them in parallels. after deleting bootcamp i haven't had a problem however in trying to work out what it was i noticed that instead of displaying the apple logo first up when i booted the machine it held the folder with ? on it for a minute. after getting rid of bootcamp this no longer happened.
    i dunno how or why but it no longer seems to be randomly resetting and not turning on. i'm hoping that its fixed becuase i really don't wanna have to send it in to apple for some of the fixes other people have had to do.
    anyways i just thought i'd post it incase it helps someone.

    Anybody have any ideas?
    I shut it down for a couple days. Just tried starting it up last night and it only made it to the login screen before it shut down again. This time it didn't try to turn back on.

  • MacBook 3x went to service center, still random shutdown, what to do next?

    Hi! Mine is week 17, and mainboard already replaced for 3 times. The last one they replaced the battery also.
    There is no Apple Center in here, I deliver it to the local authorized Apple service.
    I just got my 3rd replacement yesterday, and I noticed from the first place that it got blank gray screen on startup & can't sleep using the Energy Saver. But I waited long enough for the repairement, so I decided to take it home anyway. At home, I did the commandopt+pr and reinstall it back to 10.4.6 using the equiped cd. But still it can't sleep using Energy Saver..
    But the blank gray screen problem is gone.
    Today I calibrate (since they replaced the battery with brand new one), after the process done (5 hours sleep, zero battery), I plugged the magsafe and I heard looping click sound, and it went random shutdown again!
    And it goes shutdown on: yes dev null
    I just do the commandopt+pr, and the yes dev null havn't invoked the shutdown. But from my previous shutdown experiences, it will go crazy random shutdown in about 3 days ahead from now.
    So what to do next? going to the authorized service again?
    I'm sick and tired now.
    Also the outer body case is suffers little scratches, and it's getting mucher and mucher everytime I got it back from repairement.
    Oh dear God do help me! All I want is for my money back, at least a new replacement for my MacBook.
    And they said Apple wouldn't allow it.

    Since you're not actually turning it in to Apple for repair, I wonder if the repair shop that's doing the work knows what they're doing. Since you've had the logic board replaced three times, that's pobably not the solution. I had the random shutdowns and verticle lines on the display, and Apple replaced my heatsink and then erased the HD and re-installed to factory settings, 10.4.6. I then migrated my data from my backup HD, updated OS to 10.4.7, and installed the SMC firmware update. No problems since then.
    Many other users have had their logic board replaced more than once only to continue having the problems. Some have had logic board replaced once and then no longer have problems. Others have had other parts replaced, such as in my case and have had no problems.
    Apparently each MacBook has to be diagnosed individually to find the problem.

  • Temp fix to random shutdown (plug AC/remove battery)

    I avoid this discussion board b/c of the hardcore fanboy-ism (rated members is a joke) but I want to drop off this temporary fix for random shutdowns:
    Plug in your power adapter and remove your battery.
    It seems to lock the cpu at 1ghz even at 100% load under the: "yes > /dev/null & yes > /dev/null" test.
    I have been running this test for over 30min now with no random shutdowns where before I could not survive the 1 minute mark.
    My cpu is now running at 1.0ghz/151F/100%.
    Try for yourself and post your results.

    Good News!
    Last week I got a new logic board for my MB. After two hours working the MB shut down again!
    I called Apple Care to get further informations and told them about the fix on macfixit.com the day before yesterday. And guess what... today my service provider have done the job!!!
    I have made some tests right now... over 2h running with 100% CPU usage at 1.83 GHz. Bofore the repair it shut down after 1 minute under same condition.
    It seems to be ok now. Tomorrow more reports....

  • 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?

  • Random Shutdowns Started Again After Fix - Some Questions for Others

    ::sigh::
    After a very prompt repair followed by 3 weeks of constant use with no problems, tonight I had another random shutdown. (Here we go again.) I never was able to find anyone at Apple who could tell me what they fixed (it was not a logic board replacement) but apparently it wasn't a permanent fix.
    Some observations and questions:
    When random shutdowns start, my "previous shutdown code" in the system log changes to -72, and continue to register as -72 even when I shutdown the computer myself. During the period when the system was working after the repair, shutdown codes were always 0s or 3s. Have others noticed the same pattern? In my experience, once that first negative code appears, it doesn't change back to normal, regardless of how the computer is turned off (except after the repair).
    Also, tonight was the first time since my repair that I used the 3-prong power cord with the AC adapter (rather than just the two prong). Could there be any connection (perhaps a faulty cord sendinga surge to the system and damaging something)? During the last round, shutdowns occurred whether on AC power or battery, but I'm wondering if the use of that cord may have triggered the problem in the first place. Has anyone that has had random shutdowns never used the 3-prong cord at all?
    The other thing I've noticed is that importing digital camera photos into iPhoto often seems to trigger shutdowns (not all of them, but some of them). My random shutdown tonight happened after editing photos I'd just imported from my camera (and right after I ejected and unplugged the camera). Could the connection to the camera somehow cause a problem? Has anyone who has had random shutdowns NOT connected a digital camera or used iPhoto?
    Just grasping at straws here to try to figure out what causes this problem (since apparently Apple hasn't figured it out yet). Looks like I'm going to have to take it back again. I love my MacBook better than any PC I've ever had, but I never had these kind of hardware problems with my PCs (and if I did have a problem it was usually pretty simple to troubleshoot and repair).

    I think you're confused, it's not as simple as that.
    Here's why - I just ran two yes terminal sessions on my wife's MacBook and let it run for 15 minutes. Fan came on, system is running warm but running just fine.
    On my RSD MacBook, while I was at the Apple Store, trying to demonstrate the RSD it ran two yes terminals for like 5 minutes and kept running however when I closed Terminal - wham RSD.
    It IS NOT heat related. Most likely the system "thinks" there's a heat problem by a bad sensor, wire whatever.
    If I can't run my MacBook at 100% (actually 200%, both cores) for as long as I need then it is defective and should be returned to Apple.
    When my MacBook was working I ran EVN (Escape Velocity NOVA) which runs under Rosetta, man that thing sucked the battery dry in less than 60 minutes and the system got pretty warm too. BUT IT KEPT running and didn't shut down. When my system was acting up I couldn't even browse the Apple web site and ut would shutdown.
    Greg
    PS I installed the SMC update a week before my system started having RSD.

  • Random Shutdown Fix

    My 2007 Black Macbook has the Random Shutdown Syndrome, and I want it fixed. For the love of $1400 in what I thought was a fantastic investment, how do I fix RSS?

    Yes. Typically something like iMovie that requires a little more oomph, but just yesterday I tried to watch a DVD and it happened. I've noticed it actually happens more when connected to AC power, but it happens without being connected as well. Here is the system profile battery information from just now:

    And why would I need to boot from my install disc to run Disc Utility? I have not done this.

  • Why did this fix my random shutdowns?

    They started after a genius removed and replaced my battery. I then did the same thing, and haven't had a shutdown in two days with multiple power up/down cycles. Could a poorly seated battery actually cause a random shutdown?

    was it shutting down when it was plugged in?

  • To Everyone with Random Shutdowns! (Solved! REALLY!)

    Hey all,
    I had posted about a week back about my Macbook (Core duo white, late 2006), it was having the same symptoms as some of the others with the known random shutdown syndrome (RSS). Like many others I had thought it was the end of my macbook and the logicboard needed replacing because that is what the 'genius' people do, but I was still wondering what would cause it. It would randomly shut off! (or so I thought) I'd be typing in Safari, watching a youtube video, and even playing games, it would just shut off and I could hear the hard drive spin down. I'd restart and it would do it again sometimes right away, sometimes hours later.
    This got me to thinking (like others have said) that it must be an issue with over heating. To test my theory I backed up my HD, and tried to reinstall Snow Leopard after zeroing the HD (as a fresh install). During the install process the Macbook's fan started to get loud and then it happened, it died again! So, this proved to me that it is NOT a software/OS issue at all, which means the said efforts in other posts of changing screen saver and energy saver settings had nothing to do with the cause! Aha moment!
    I thought to myself... something is making it shutdown, obviously, and has to do with too much heat as the fan was going crazy even while reinstalling the OS. After reading many posts on different support forums I came accross the possibility that it could be the heatsink and/or sensor that is attached to it. I also found out that this "RSS" only applies to the non-unibody, core duo, and core 2 duo macbooks... you know what that means?
    These models are the only ones with the shared memory and GPU on the same heatsink! GAH! A possible solution presents itself? To make a long post even longer... I removed the keyboard, carefully unscrewed the heatsink and fan and what did I see? Cracked and dried out thermal paste on the CPU AND GPU, they are both under the same heatsink after all, this was bad, really bad.
    Luckily I had some Arctic Silver thermal paste in a tube from years ago when I upgraded my PowerMac CPU. Using some rubbing alcohol and a soft cloth I removed the crud on the heatsink, processor, and GPU (I might add that there was way too much paste on there in the first place). I waited an extra few minutes to make sure the alcohol evaporated, and then I applied a small (dime sized) amount of thermal past directly onto the two chips, I aligned the heatsink carefully and gave it a very small gentle push down onto the chips, reattached the sensor wire to the mainboard, and screwed the heatsink back in.
    After putting the keyboard back on and making sure all screws were in... I immediately turned on the laptop and reinstalled the OS. The OS install took approximately 10 mintues! (crazy!) The last time I did that it took over 30 mins to install! I was stunned!
    After the OS installed I let the computer idle and shut down, I let it sit for about an hour to allow the paste to contract as it cooled. After starting up again I immediately downloaded Temperature Monitor and installed it (I did have it running when my mac had RSS by the way), here are the results to prove my theory:
    My Macbook with RSS:
    CPU1 and CPU2 Idle temp - 114 degrees (F)
    Heatsink temp - 128 degrees (F)
    Approximate over heating temp - 184 degrees (F) (causing the heatsink sensor to shutdown the laptop)
    My Macbook with new high quality thermal paste:
    Idle temp of CPU1, CPU2, and GPU - 77 degrees (F)
    Heatsink temp - 84 degrees (F)
    Running temp with adobe CS4, youtube, and typing this message - 103 degrees (F)
    Pretty amazing if you ask me!
    Before I applied the thermal paste my Macbook took at least a minute to start up with a fresh OS install, now it only takes about 15 seconds! I have not heard the fan spin up and go crazy since! And I can't even explain to you how much fast it is now!
    This does prove that Random shutdown syndrome (RSS) is caused ONLY by your GPU over heating due to old thermal paste between the chips and heatsink! A design flaw by Apple? probably not because thermal paste will crack and dry over time.
    This also proves that energy conversion to data in the chips can decrease because of over heating, causing the computer performance to dramatically drop!
    So before you take your out-of-warranty macbook to Apple or a repair shop, see what your internal temp readings are and try to replicate the problem with over heating your CPU/GPU! This was a 10 minute fix! I am still amazed at how much faster everything is, and haven't had a random shutdown since! I hope this helps alot of people that think they are out of luck and have to pay to get it fixed!

    I too have this problem as well and it has been getting worse lately, I don't know what to do anymore. Here is a little info about my macbookPro. I have the late 2008 unibody model, i bought it in late 2009 Refurbished from Apple. Recently my mac has been turning off out of nowhere. I may be doing something and all of a sudden it just shuts off, it usually happens faster when i start to open up more programs like Photoshop or Final Cut Pro. My mac is out of warranty now and i dont know how much apple is going to charge me to fix it. i mean they want 50 bucks just to talk to them on the phone (ridiculous if you ask me)!.
        I have a temperature sensor installed and here is my data

  • Macbook problems, hard drive crash, random shutdown, freezes

    I bought my macbook used a few months ago, and it worked flawlessly until about 3 weeks ago. The system started freezing and not booting (getting folder icon instead of apple at startup). I ran drive setup and tried to repair the drive, but this did not fix the problem. DiskWarrior also could not fix it. I pulled the drive and installed a new hard drive, as I wanted a larger capacity anyways. All my problems appeared fixed for about two weeks, then similar problems began occurring. I backed up all the files I needed to an external firewire drive and attempted to reformat the new internal drive. Drive Setup says it can not reformat the drive - can't mount it and if it does, the drive disappears while in the process of formatting. I pulled the new drive and am having it replaced under warranty. I am using the firewire drive to run my computer, and this seemed to work fine for a day or two until the computer just started shutting down with no warning. Everything goes black, including the little light on the front of the computer. I have to hold down the power button for 10 seconds before it lets me start the computer back up. I had read this may be a memory issue, so I ran memtest and it says the memory is fine (I need to do it in single user mode still, however). I also tried pulling both sticks of ram. They are both 1GB crucial memory. I put each stick in by itself and tried it in both slots and was able to reproduce the shutdown issue with any ram configuration of either stick.
    After all this, I realized the firewire drive was only running 10.5, so I updated all the software through software update, and it is now running 10.5.2. It seems to be working better as I have not experienced a random shutdown yet, but I'm anticipating it may start back up soon. Today, however I experienced a different problem - the screen froze on me and the only way to get anything to happen was to force a shutdown with them power button. It's restarted and seems to be working fine again for now.
    I've run some logs and here's some things I've found:
    When the latest freeze happened, I got this repeated over 100 times:
    Apr 29 11:04:31 jon-turners-macbook quicklookd[536]: CGContextClosePath: no current point.
    I've also seen this:
    Apr 29 11:18:19 jon-turners-macbook kernel[0]: Previous Shutdown Cause: 3
    Apr 29 11:18:19 jon-turners-macbook kernel[0]: GFX0: family specific matching fails
    Apr 25 19:19:50 localhost kernel[0]: hi mem tramps at 0xffe00000
    Should there be anything else I can check? I would run Apple Hardware Utilities, but I don't have the original disks, just the Leopard installer. I have Disk Warrior, but it seems strange this would happen with multiple systems and drives. I'd like to get Techtool Pro, but haven't had the money/time to order it yet.

    Thanks for the replies!
    Yeah, I think it's the HDD. I was just worried that the RAM was bad and corrupted the HDD or something, but given the symptoms I think you guys are right. Ordered a 7200RPM 320GB HDD off Amazon Prime...will be here tomorrow
    I'll post how it goes after I finish installing it. I'm backing up as I type.
    I wonder if I can fix the ir port and the sleep indicator light when I install the hard-drive. The sleep indicator light never turns off. It stays on as long as my computer is on, only turns off when I shut it down.
