Another Random Shutdown Thread!

Hey all
So, ive got the random shutdown prob. Ive downloaded the firmware update and when I go to install it im told its not needed, I tried the battery update..and still the prob persists. Is it just that my battery is a dud?
Thanks !
Kasra

Yeah, I was suprised about that too. I'm sitting outside the Apple Store right now with my replacement. I demonstrated the crash once to the guy by running yes, and then it crashed again on him while he was trying to look at the logs.
This one's a week 32. I'm currently running yes in two Terminal windows and all seems well. Let's hope it stays this way!
edit: I think the problem with my old MacBook was with the temperature sensors or with the fans, because I didn't hear the fans kick in once while I was using it and the fans just kicked in on this one. Strange thing is, it crashed even when it was cool to the touch. Just thought that was worth mentioning...

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.

PS I installed the SMC update a week before my system started having RSD.

After a year, another chain of random shutdowns

can anybody tell what's going on with my computer from a remote desktop? by now that should be easy.
i had random shutdowns problems last year, one month after buying my macbook pro, but they seemed over after the download of the oct.2006 firmware. now they're back. as random as they were. could it be possible that the new battery update clashed with something? the appearance seem to have occurred just after that update. maybe a coincidence. but i had started to have battery failures - computer shutdowns at 95% of battery charge, with 28 cycles count - and was about to go replace it (the sick battery).
just i cant stand abandoning my computer in a dark room with many others, so i didn't turn it in and kept it on ACDC.
anybody may guess what i should do to avoid a premature death?

There's nothing anyone here can do about this. We're all just users like you. Was the phone still covered by warranty? Was there an explanation from Apple?

Random Shutdown Because of Heat Sensors?

I bought my white MacBook in mid-May (week 19 production) and it worked fine with the exception of a whine when I did not have the iSight Cam on, the occasional mooing after using the computer heavily then using the CPU lightly for a while, and the discoloration. If you ask me it wasn't that much of a set back because this computer was fast and reliable... or so I had thought!
All of a sudden about a week ago, after I had the discoloration fixed, thanks to AppleCare (which only took 5 days), my computer shut down randomly in the middle of light usage...
At first I had thought that my external hard drive was the problem and I was very upset that this had happened. I tried to reboot my computer, but all that would happen was the usual DVD drive start up sound and then it would turn off again. I tried about 5 times to restart it with no luck, so I walked away. About 20 minutes later I was able to start it back up...
After not using my external hard drive for a day, it happened again, in the middle of normal internet browsing and listening to music it randomly shutdown. I thought that maybe it was an OS 10.4.7 issue, because I had not had any problems with x.6, so I erased and restarted from scratch, and once again, another MacDeath. Once again, I thought it to be my fault in my installation of 2Gb of RAM. I re-installed the custom 2x256 RAM that came with the computer ( and will remain in my hands forever, because you can't even pay someone to take away a stick of 256Mb RAM these days) well after the old RAM was forcefully shoved back in, it died again! This is when I started to get mad...
I put up with the whinning, I put up with the heat, I put up with the discoloration (for a while), but now this? WHY!
Over the next week it happened almost daily and sometimes when I would turn on my computer after it being off for at least 5 hours, it would load my home screen and after about a minute I would hear the fan come on for a few seconds, and then it would die again. I noticed that most times that my MacBook would shutdown unexpectedly, the fan had just turned on for a few seconds or I was playing a game and the fan was already on...
So today I called AppleCare and I had to wait about 30 minutes before I talked to someone... (When I called last time about discoloration, the wait was about 5 minutes) So either there are more and more angry customers calling, or Apple is firing employees to increase their stock value...?
When I finally got through the man told me that it was most likely not the Logic Board, but instead FAULTY HEAT SENSORS and/or FAULTY HEAT SINK APPLICATION. I won't lie I have seen Core Duo Temp show readings as high as 91 C (about 196 degrees F). I knew that this things got hot, but not so hot as to start a fire if left on too long....
So I am getting a box from DHL tomorrow (woohoo) MacB. and I get to part ways again, but this time, from reading many threads, I assume our time apart will be much longer approaching around 2 WEEKS!!!
All I hope is that AppleCare will fix the heat sensors that are supposed to shutdown the computer when it gets overheated.... I have to go to school in about a month and I will not have time to deal with these kinds of issues! I really like the MacBook and all of it's features, but I did not sign up to get a MacDieOnMeBook!

As of yet i'm not exactly sure about the heatsink problem, although a few in here have reported machines that work well after having this part replaced, while others who only had the MLB replaced reported a recurrence of the problem.
as for the volume indicator, i noticed that mine did that too, but it was in fact muted whether or not the tool bar indicated it. i dismissed this as a small quirk, similar to when my volume indicator didnt change as i pressed the volume buttons on my old laptop. but so long as there was an acknowledging "squirt" noise on the computer indicating change of volume, that shouldnt be a problem.
good luck withyour MB

I've been having random shutdowns

Hello, I've been having random shutdowns for a while now. It is completely random and sometimes the screen will flicker when it shuts down and sometimes not.
Here is the report.

Will the console log show a history of random shutdowns?

My macbook has suddenly started the random shutdown problem. It started a couple of days ago, I'd had no problems up until then. At one point today it was shutting down immediately on waking from sleep, and then would only stay on for about two minutes with the fans racing before, bang, off it would go. I left it alone in exasperation, then returned to try again, and this time it lasted around an hour before shutting down repeatedly again. I will need to take it home to the UK to my local Apple service centre and I am worried that if it doesn't actually shut down in front of them when they have it they will tell me there is no problem and won't repair it. I know that this macbook has the RSS issue now but it really is random, so can I prove it from the console log? I looked through this just now and of course most of it means nothing to me but I did notice that there was a line saying "cause of last shutdown -72" occuring many times since this started. Does anyone know what this refers to and will it show that the problem is definitely happening?

What does the holding the button down trick do?
From the Apple article I referenced in your earlier thread:
"If your MacBook is in a state where it will not remain on long enough to install the update, wait for the issue to reproduce itself. Once the MacBook has turned itself off, turn the computer on the by holding the power button down. Keep the button down until you hear a single long tone. Once you hear the tone you can release the button, install the recommended updates, and restart as you would expect."
Allegedly, this throttles the CPU to 1 GHz.
And I am slightly worried that a2dox says that the
problem returned even after the repair..!
Different experiences for different people, during the period when Apple had not yet figured out the problem. Their contract repair facility was doing different repairs, some getting heat sink replacements, some logic board replacements, some both, and, later, some a differently designed heat sink. When one of those repairs didn't fix the problem, they would do another.

Overheating or random shutdown?

Last night I while I was using my iMac it randomly shutdown twice, one right after another.
I have had the random shutdown problem in the past but have not experienced one for quite some time. (I had taken several steps to fix, including running the disk utilities and deleting some power management file. Whatever I did seemed to be working.)
I had also been using iMovie, exporting movies, all day. I had also been heavily using iPhoto and Firefox, moving photos out and onto Facebook. The case was hot to the touch and iStatpro said that the power supply was around 159 degrees F and the CPU was around 135 degrees F. Is it possible I triggered some sort of safety cutoff?
Please help me out here. I love this computer but the random shutdowns are totally killing it. Thanks in advance.

Hello All,
Here's my experience with unexpected shutdowns...
My 20" Intel iMac is 6 months old - August 08.
- After shutting it down one evening as per normal, it just wouldn't turn on the next morning. Nothing I did worked: different power socket, changed the fuse (UK plug) etc. When I had just about given up carrying it around the house, it suddenly came back to life. Went to the shop to buy milk, got back and off it was again. Weird. So I spoke to Apple Care who suggested I take it down to the Apple Store in central London, UK. I laboriously did so (try taking the underground with an iMac... not fun) and dropped it off mid afternoon.
- Got a call the same evening from Apple Store: my iMac turned on fine first time (typical), tests were being run on it (basically stress testing the processor with multiple processes), and it was fine. No fault was found, I could go and pick it up.
- So I take it back home the next day, again battling with London commuters with my heavy, bulky iMac box and plug it in. All fine. Work all day on it as per normal (nothing intensive). Then at about 10pm, it just turns off. No warning, nothing. Just off, and this time its staying off. I let it cool down, nothing. Diffent plugs, nothing. Change the plug fuse, nothing. Next morning, nothing. Its dead.
- So I head off directly to the Apple Store again, iMac in hand, and battle it out again with London commuters on the underground. I explain the situation, am promised this will be a priority repair...
- Eventually, after 10 days (Christmas got in the way), I get a call that it is ready. Two items of hardware were changed, namely 1) power supply and 2) Cable/DC Power/SATA/Inverter. Though none of them were actually faulty, they are the items that can cause sudden shutdowns...
- I pick it up, and it seems fine since. But upon switching it on, I noticed the whole bottom half of my dispay was dim. Bright at the top, grey at the bottom... Another chat with Apple Care (by then am on first name terms with the whole team), we do various hardware resets to no avail. Am advised to drop it off at Apple. So off I go to the Apple Store again.
And I just got it back again.. with a new LCD display...
(http://discussions.apple.com/thread.jspa?threadID=1730239&tstart=0)
So the cost of all repairs to my 6 months old iMac is now more than half of the overall cost of the machine. Still, credit to Apple for not quibbling on any of the above issues, and fixing them (relatively) quickly and efficiently.
Now lets hope my iMac stays on and stays bright...

Random shutdowns/screen off on Mavericks

I've been getting random shutdowns on my MBA 2013. It almost always happens when I've closed the lid to put it to sleep. After that when I open it the screen always stays black and nothing happens. I have to press down on the power button for a while to get it to reboot.
I've noticed it happening since I upgraded to Mavericks. I thought it might be a problem because I just updated so I did a clean install last week but it's continued to happen.
Any ideas what this could be due to?
I have a log from a shutdown I had last night. If anyone could help me out that would be nice.

2.5 y/o macbook develops random shutdown?

Hi,
my 2.0 ghz core2duo white macbook has done the random shutdown thing 2 nights in a row, and its never happened before. no warning, no prior indication, it just instantly shuts down. I haven't heard of this developing on an older macbook. Both times the computer was under light load, on battery power and had maybe 20% charge left.
I did see one thread where on old battery may be an alternative cause, so I downloaded the suggested coconutbattery, which tells me my battery has a capacity of 4036 mAH now, as opposed to 5020 when new. I don't know if this is significant but it doesn't seem that 80% of the original battery capacity is too bad.
Does anyone have experience of this happening, or any helpful info for me?? This is a pain as I was hoping to use my macbook for some live music soon... not too confident of that now.
thanks, Simon Gregory

I'm not sure resetting the SMC is good advice, according this article:
http://support.apple.com/kb/HT1894
It says only to do it very very specific issues, and random shutdown is not one of them. The article specifically warns against doing it as a troubleshooting measure...

MacBook Pro Core Duo 15" Random Shutdown worsening

Have had my MBP for over 18 months now, and any glitches have been software so far.
Two nights ago, I was working on my MBP and suddenly went into an unwakeable sleep. After resetting, I could start up intermittently up to 5 minutes, but it seems to have gotten worse, to where I'm at a point where I can only manage a few seconds of startup before it blacks out again, either off or again, into an unwakeable darkness.
It's the same with just battery, battery & AC, or just AC. It wont stay on long enough for me to start from CD, neither will it stay on to let me Firewire my info/account to another Mac.
At times when I cannot start at all, I can hear a small 'electrical snap' (best description I can give) when pressing the power button, whichever combination of power source I use. I guess this is normal, but I wouldn't notice it usually.
For anyone who've had their MacBook Pro with "Random Shutdown" fixed by Apple out of warranty, could you give an example of cost?
Thanks
Sion Joyce

i dread to think how much it would cost, but i was having random shutdown problems as of last week. completely out of the blue
but, the latest Firmware update seems to have solved it! not before i went and bought another battery of course
one thing i have noticed though is the eta on the battery fullness is completely random now, it'll go from having about a minute left to having an hour and 30mins

Macbook Pro 15 " 2.53GHZ mid 2009 random shutdowns

Hello,
I've a Macbook Pro 15" 2.53GHZ mid 2009 that have random shutdowns and when he shutdown he dont turn on in power button, because the button dont do nothing at all. Sometimes, only after hours the macbook pro automaticaly turn on. I have already clear the fans and replace the thermal paste but with no sucess because problem still exists.
What's the problem with this mac?
Regards

Random shutdowns: my experience, and a suggestion

I own a BlackBook whose random shutdowns began a couple of weeks ago.
During my first trip to my local Genius Bar, the guy behind the counter reset the PMU and PRAM, and was unable to reproduce the problem, and sent me on my way.
The random shutdowns continued.
During my second trip to the Genius Bar, the guy was able to boot the machine from another drive, and was able to reproduce the problem. The machine was sent to the repair center for servicing. I got it back a few days later.
Random shutdowns have still occurred, but I find that if I reset the PRAM as the machine is booting, and wait for at least three startup chimes before letting go of the key combination (control-option-P-R), the machine seems to stabilize and not shut down on its own, at least so far.
Before repair, the machine was also exhibiting the "vertical colored lines at startup" problem. Before that, it needed a replacement power adapter and a replacement battery (the battery was refusing to take a charge or even be recognized by the computer).
Various theories for the cause or causes of the problem with random shutdowns have been suggested -- along with a number of magic-bullet solutions from different sources. My guess is that even Apple isn't sure what's causing the issue, and there's certainly no foolproof solution that the user can apply. We'll just have to wait and see what comes of the investigations.
Despite these problems, I still love the BlackBook and think it's perhaps the most beautifully designed computer ever made. I assume that once these growing pains subside, Apple will have a total winner on its hands.
MacBook (black) 13" Mac OS X (10.4.7)

I have a whitebook bought in June, shutdowns started about 6 weeks after I got it. Did the whole tech support line thing several times resetting various things etc. No change. Sent it in for repair with a strong encouragement that it would only take 48 hours. It is now 10 days later and repair is still on hold. Sent in several "why is this dragging on" and got nice automatic reponse saying they would respond in a day or two. No real responses yet. Called today the helpful tech said they would check and see what was holding things up and let me know when I called back in 48 hours. Assured me I would not be without my Macbook more than a week longer. Have missed work and have a presentation on Friday that I will have to do without it. Had I known it would take this long I would have taken my chance that it would not shut down mid stream in the presentation. I am very disapointed with Apple at this point. Have been a long time user and own stock etc. This is the worse customer service I have gotten on a computer problem, personal or business. Apple needs to realize they have a batch of lemons on their hands and bite the bullet and replace them. I am not encouraged to hear others are getting their books back repaired only to find the problem on going.

[solved?] possible reasons for random shutdowns

Several months ago, my laptop started to suddenly shutdown for no apparent reason. Initially, I assumed it was overheating. Lenovo had a look, found nothing but replaced the thermal paste anyway, gave it back.
The issue continued so somebody from IT stuck my laptop in a server room on top of a hot computer and stress tested it for a few hours. Conclusion: can find nothing wrong, definitely not a heat problem! (Laptop never went above 65.) They ran a bunch of hardware tests as part of this, got my cable and adaptor tested etc.
Next theory: issue had only ever occurred on one level of the building (in my office) and it turned out there had been another issue with another laptop in that area and it turned out to be shutting down to protect itself due to spikes in the power supply. A UPS solved that issue. One is currently on order for me.
Meanwhile, last weekend I had the issue occur twice in a friend's house in Birmingham. Even more worrying, however, I just had it happen here at home even though I use the machine extensively here and have never seen this happen here before.
I'm guessing this rules out the environmental hypothesis although I'm by no means certain of this.
That leaves: hardware or software.
Hardware is a pain - Lenovo already ran it for 48 hours straight and found nothing. Moreover, although I have paid to extend the warranty and although they've taken my money, I've so far been entirely unsuccessful in getting Lenovo's system to recognise the extension. In any case, with the holidays and everything I'd rather be sure of what I'm dealing with before giving the machine up for an extended period of time. I cannot reliably reproduce the issue so it is hard to troubleshoot.
So I would like to know what possible software issues might trigger apparently random shutdowns.
The shutdowns are immediate. One minute I am working on some document or whatever. The next the machine is off. journalctl shows nothing except:
-- Reboot --
If it was a hardware protection feature, would this get logged?
It does not reboot - it powers off - but I always have issues with reboot since I switched to systemd. Generally, it just powers off instead. [Oh, and before anybody tries to blame systemd, the random shutdowns started before I switched to systemd.]
I've checked the RAM.
Any suggestions, however unlikely, are welcome at this point.

Thanks. The adaptor, cable etc. was "PAT tested" by the electricals person in our building and they checked the fuse etc. in the plug as well. Moreover, the laptop never usually has a problem switching from AC to battery and back. My battery is more than adequate for this sort of purpose and, if the battery did run low, the laptop would automatically suspend to RAM. Also, I know if this happens because, among other things, the display is set to dim on switch to battery. When the power supply has disappeared due to a power cut or just unplugging it, the switch has always been flawless.
I've just been jiggling and shaking and rotating the laptop itself as suggested above with no effect whatsoever. I've also tried pressing around the edges of the casing just in case I'm somehow putting pressure somewhere and that's affecting things. (I assume if it was pressure due to typing or touchpad, it would be happening all the time.)
I've also just spent a while jiggling the adaptor and both parts of the cable - also with no effect.
The one thing which makes me reluctant to test sans battery is that I've read that the batteries in ThinkPads serve some sort of protective function in case of issues with the power supply and that you shouldn't use them without the battery for that reason. (Somewhere on Lenovo's site but it was months ago so I can't remember where to check the details.) In case there is an issue with the power, I'd obviously rather not fry the laptop. (But it seems weird if it happens in several places in that case...)
I'm not sure about the cold boot comment. Do you think a cold boot might help? If so, I already performed one yesterday as I opened the back to look for loose connections. So if a cold boot might help, I'll just have to see. I've done cold boots before, though, after opening it up to look for issues following shutdowns.
These issues appeared several months ago and I've reproduced the issue with the LTS kernel a while back. So if it is a regression, it has been around for a bit. I might try a live Ubuntu USB. (I don't have an optical drive.) The problem is that a negative result won't really prove anything because the issue is so random. Given that yesterday is the first time it has ever happened to me at home and that even in my office I've sometimes gone three or four days without problem, a couple of days testing won't cut it. (And will make it difficult for me to get stuff done!) It might be best to wait and try it in my office after the holidays - if it worked for, say, a week there without issue, that would strongly suggest something in my Arch setup. (Or something about the hdd, I guess.)

I did wonder about the watchdogs and whether I should try turning (any of?) them off. But I suspect this thought just shows my ignorance of these things.
I don't think there's a fan in my power supply - it is just a brick type adaptor between the AC and the laptop. If it is the battery, it would be odd that it only ever happens when I'm plugged into AC. (Again, I use it a lot more on AC and the problem is random so this need not mean much.) One difference between battery and AC is that laptop-mode tools is configured to disable the NMI watchdog on battery. But again, I don't understand enough of what this means to know whether this is even vaguely relevant.
My graphics is intel so I'm not using any closed source drivers from Nvidia or ATI. The driver is currently set to use the default acceleration. QT is using default rendering (X11/XRender) rather than Raster or the experimental OpenGL.

Arghhh random shutdown ...

I've had my MacBook for about 2 months now and have never had any problems with it ... until two days ago.
It was working fine then it powered off, and after switching back on it would power off after a few seconds.
It was fine yesterday but has done it again today, it sems to start better without the power cable attached.
Having seen several threads about this I can't decide whether I should take it into the apple shop and ask them to repair it (replace the heat sink?) or not.
One thing I hve noticed is that the fan doesn't seem to come on very much at the moment.
I've just installed core duo temp and the average temp i about 50 deg C - which is much lower than some of the 80 temps i've been seeing.
Please note that when it's been crashing i've just been doing simple web surfing - it's never crashed during the month i've been playing WoW on it, e under heavy load!

P*ed off MacBook owners (especially ones they've
just culled from Windows) are going to remember this
and are already getting pretty steamed.
Yep, that pretty much describes my situation. My Macbook is my first Apple product ever, and after a pretty good honeymoon with the MacBook, the random shutdowns have started happening regularly. Actually, they aren't so random anymore; they happen every time I turn the MacBook on from a cold state. When the temperature gets up to a certain point, poof, the power goes out. Holding in the power button usually allows it to come back up again, but not always. If I can get it to stay up long enough, it seems to warm up enough to allow it to stay up indefinitely. Even if I put it to sleep for a few minutes, it will still work fine since it is still warm inside. When it gets cold, the problem cycle starts all over again.
Being a computer hardware engineer myself, I can understand design flaws in early revisions of a product. What has worried me is all the horror stories from MacBook customers about how Apple has been treating the problem with random clueless solutions and how they have been treating customers. I have been painfully living with the shutdown problem waiting to see some positive stories from customers. I don't want to waste my time dealing with Apple until I feel that they really understand the problem and know how to fix it in a reasonable amount of time.
Meanwhile, I use my 5 year old non-Apple laptop which has been quite reliable and has never randomly shut down on me. I avoid doing anything important on the MacBook since it is so unreliable. I'll contact Apple when there are some indications from customers that Apple has truely solved the problem. I guess in a month or so I'll know whether I'll ever do business with Apple again.

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)?

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.

Another Random Shutdown Thread!
