X230 sudden shut down issue

Recently bought an X230 and realized that is going to sleep at what I thought was a random time and I so I tried messing with the timmer settings. Then I realized that its not a random time, it goes to sleep/suspend whenever its plugged in to AC power and I ever so lightly move the AC plug on the back of the laptop. If I knock the plug, tap the plug, and even when I unplug it sometimes it goes right to sleep/suspend and I have to start it up again.
What in the world?
Anyone else experiecne anything like this?
Thanks in advance!

(1) what version of Windows are you using (7, 8, 8.1)
(2) is the laptop still under warranty? check here: http://support.lenovo.com/en_US/product-service/warranty-status/default.page
(3) did you buy it new or used?
(4) have you updated to the latest BIOS version? (2.58 as of 4/22/2014) available here: http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS029683

Sudden Shut Down Help

I've posted a couple times about my shut downs, but I expected something different than I got over the past week. I had two sudden shut downs this past Tuesday, about 8 hours apart, not apparently based on anything I was doing differently with the MacBook. I had one maybe 2 or 3 months ago, but got a "OS X suddenly quit" message when I rebooted -- basically OS X crashed before it went to sleep and the computer shut down to protect it; I don't think this had anything to do with sudden shut down issue. So that's only 2 in more than 4 months. I haven't had any problems since Tuesday.
I was planning to take the MacBook in to the Apple Store today to be sent off for repair. But for 2 shut downs and 2 only I'm not sure if I see the point. Especially since I've read at least one report of shut downs returning even after the repair with the newly revised heat sink and logic board. I don't really care to send it off for repair until we can say this is truly a problem and this will truly fix it. Yes, I'm making regular back ups so I won't lose anything if my MacBook becomes impossible to start up.
For the record, this is the only issue I've had with my MacBook. Case and keyboard just great. Only discoloration caused by some ink I got on it. Screen just great, bright, clear, perfect size. Magnetic latch to die for. Trackpad button was sticky when I got it but as loosened up perfectly with use. The edge of the keyboard deck is a little sharp as my wrists and the back of my toddler's head can attest, but I suspect this is something of a design trade-off for plastic used. Did I mention the keyboard and the magnetic latch?

I'm not saying I won't have it fixed; I'm saying I'm not sure I should send it off today. A full replacement MacBook that potentially has the same problem doesn't do me any good; neither does repair with revised parts that don't actually fix the problem.
I'm just wondering if I shouldn't put it off until a) it's worse than twice a week, or b) they have positively isolated the cause of the problem and can surely fix it the first time.
I didn't think they have any way to test for a sudden shut down problem, other than watch it and see if it happens, although it may not since it's intermittent.
I have no problem sending it off for repair. But sending back once or twice to fix the same thing is going to annoy me. That's why I'm thinking of waiting a couple weeks until the verdict is more or less in about this latest batch of fixes.

HT6001 my mac has started freezing and suddenly shutting down on me it seems as if every process has slowed down since downloading this last update of 11.1.4, any solutions? Because it shut down in the middle of a test twice now, saying keyboard issue.

What you describe sounds like a hardware issue. Unfortunately, you'll need to get that checked out by Apple. If you have an Apple Store near you, make an appointment with the Genius Bar and take the machine in for evaluation.

Suddenly Shut Down my mac book pro, late 2011

Hello guys, i need your help.
Last 2 weeks, suddenly my macbookpro shut down, and it makes me shock.
After a few second shut down, i try to turn it on.
it just make sound like turn on your mac and suddenly shut down again.
It shut down for 3 times and more.
When i plug in the charger, it turn on.
But after i unplug the charger it suddenly shut down again.
i try to shut down my mac properly, and when i turn on again it works.
My friends say that it could be my battery, i checked it, and my battery was normal.
And i search about this issue, some people say to reset SMC, i dont know if it would works or not.
Did reset SMC will makes you lose you data or something?
Now, i must plug the charger when i want to turn on my mac.
Did this a serious problem or not? i need you advice guys.
Thanks!

No data is lost due to resetting the SMC.
But after i unplug the charger it suddently shut down again
The problem may be the adapter. Try here > Apple Portables: Troubleshooting MagSafe adapters
Hopefully your important files are backed up just in case.

My iphone4 suddenly shut down.I pluged into a charger it started vibration and got heat up in off mood. I also checked it to genius he said that its battery is ok but problem is some thing else. It is still in off mod. what i have to do?

My iphone4 suddenly shut down.I pluged into a charger it started vibration and got heat up in off mood. I also checked it to genius he said that its battery is ok but problem is some thing else. It is still in off mod. what i have to do?

I am having a similar odd issue. First of all this summer i took my iphone 4 to apple because my screen had quit. I could hear calls and texts coming thru but screen was unresponsive. I was a month out of warranty so the nice fella at apple gave me a 30 day warranty, then replaced my handset with a refurb. Saturday night at dinner i was on my phine and it died. I plugged it in thinking nothing of it and went to bed. When i wooe up after the charger had been on all night all i had was the black screen with the battery (red) and lightning bolt, meaning it knew it plugged in but still did nothing. So off to apple i go. They said i was out of warranty and the problem (never said what problem) would cost 170 bucks to fix. So i went and upgraded to the iphone 5 ( figured if i'm spending that anyways may as well be on a new phone). When I got home i tinkered with the old one with all the online suggestions i could find. (Cleaning ports, hard reset, putting into recovery mode, and checking indicators for water damage which there was none). Still only saw the battery symbol. I left it alone figuring i can sell off cheap and someone else can repair. Last night for kicks i plugged it in again and it came to life! It is in recovery mode (needs to be hooked to itunes to regain functionality) but showed 100% battery charge. I went to show my bf and realized an issue. If its not plugged into the wall adaptor, it wont turn on. I figured then that if i can get it plugged in and pull it up on itunes maybe it would be fine. When plugged into the computer it wont hold enough power. It thrns on shows the apple for 30 seconds, shuts off. My ending conclusion on my own is that it needs a new battery in order to be revived. Anyone think this sounds like a reasonable conclusion? Or will i be wasting money? If i can get it restored to functional, cheaply i can give to my bf (his pos lg phone is almost toast) or sell it.

IMac suddenly shutting down

Below is what my iMac tells me when it suddenly shuts down or freezes. Does this mean anything to anybody. Quite frustrating. I don't want to buy a new machine if there is some fix for this but I also cannot afford to be without my machine while it is in the shop for a look under the hood.
Any suggestions would most appreciated.

I was charging and updating my mini ipad last night when it suddenly shut down and will not turn on since then. What do I do to turn it on again?

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased.

Thinkpad X201 usually suddenly shuts down!

Dear all!
I have two problems with my Thinkpad x201.
1/ When I use it with battery and charging then I plug adapter out, it suddenly shuts down. I take it to my office or repair service and do the same but it not suddenly shuts down.
2/ it has been running fine but always suddenly shuts down in an instant, as if somebody turned off the power switch when temperature CPU up to about 55 degree C (using battery only or adapter or adapter + battery). But I take it to my office to use or take to repair service, it not suddenly shuts down. => Use it at home suddenly shuts down when CPU up to about 55 degree C. Use at office or somewhere else not suddenly shuts down whatever temperature CPU up to about 55 or 60-70!
I find some topic talk about this problem but haven't got any good solutions. I would like hearing all idea. Thanks all!

Had the same issue with the X1 carbon. send it in as it likely has a bad motherboard.

Operating System: Windows XP SP2
The Problem
The PC suddenly shuts down as if the power cord is pulled from PSU.
Detailed Description and what I've tried
The first days after I've build the system everything looked to work properly. I tried to run 3d mark 2005 and it ran without problem. Then the fourth day when I was surfing on internet and listening music with winamp, suddenly the pc shut down. This happens three times and I noticed that it depended from the audio device of the MB, in fact if I didn't play music the pc didn't switch down, otherwise after about 20minutes I played music, the problem occured.
So I thought the problem was the PSU, so I ran 3d mark 2005 for more than an hour and it ran without any problem! I was very surprised. I tried also to run Prime95, one for each CPU core, and also Prime ran without problem.
Another problem was that after about 1-2hours that I was connected to internet, the connection suddenly freezed and the OS couldn't shut down the pc, so I had to use Reset button.
After someday I noticed that the motherboard has 3 power connectors!!! I've connected to the PSU only the 4pin and the 24pin!! So I connected also the molex to the PSU. So I thought to have found and solved the problem, and for about 48 hours the PC worked properly, also for 6 continous hours, I can play music using the Realtek audio device and no more problem with connection.
But then again after about 48hours the same problems!!
So I've tried to disable the realtek device and to use a sound blaster 1024 Live! And it seems to work, I can play music and the system doesn't shut down. I've also disconnected the two 80mm fans, it seems to help.
Another strange thing is that now when I switch on the system the MB emits two short beeps. Before it emited one long beep. What does it mean? I don't understand the cause of this change.

True, the computer doesn't need that amount of power.....but....
You are miscalculating the powersupply.
Just because it states it can do 17A (or what ever figure) it doesn't do that all the time.
Here you have the details of how a PSU handles output, then you might have a clue what we are talking about:
Quote
3) Specify a low operating temperature for rated output. This is quite common, but again not often seen in consumer brochures, but rather tech spec sheets provided usually only on demand by engineers or corp buyers. A typical PSU operating temp statement is somthing like this:
0?C ~25?C for full rating of load, decrease to zero Watts O/P at 70?C
Examine what that says. Full power (let's say 400W) is available when the unit is at 0?C ~25?C. Hmmm. Think about this.
Have you ever felt air blown out of a PSU in a PC running absolutely full tilt (which it would have to do to get anywhere near 400W output) that felt cool to the fingers? 25?C airflow would feel exactly that: Cool, given that normal body temperature is 37 ?C.
So this PSU cannot deliver full rated power when its temperature goes over 25?C. OK, what happens to the max power output capacity above that temp? It decreases gradually so that by the time the PSU temp reaches 70?C, the PSU cannot deliver any power at all. So if you assume that this power drop as temp rises is linear, then max power capacity will drop by ~9W for every degree over 25?C.
Now having examined as many PSUs as I have over the last 2~3 years, I have to say there's not a single PSU in ANY PC I have ever used or examined that would not measure at least 30~35?C almost anywhere inside the PSU under almost any kind of load. And if/when it is pushed, 45?C is nothing at all, especially for or near hot running components like voltage regulators.
So let's say 40?C is a fairly typical temp inside a PSU. This 400W rated unit would actually be able to deliver a max of just 220W at that temp. Hmmm. Interesting, isn't it? At 50?C, the available power would drop to just 130W. No wonder some PSUs have 3 fans each capable of 50 cfm!!
Here's a simple fact: Really high quality PSUs are actually rated for full power output at as high as 50?C. The trick is get a hold of the spec sheets that tell such information so you can compare apples to apples. Or ask.
Source: >>SilentPCreview<<
I suggest you start reading on their site as to what they have to say about powersupplies.
As those PSU's DO NOT DELIVER the amount of power under all conditions....many people have blown their system to pieces already by ignoring the heat-factor.
That is we are telling all along, you don't need 33Amps....but you need loads of headroom when summertime temps are there.
Because then your PSU doesn't deliver near the ammount of power you think it does.
Also, split rails are far worse then single rails when it comes to that...heck a lot of so called splitrails are not splitted at all, like the some of the Coolermasters....
Do yourself a favor and get to know how PSU's work, as they are NOT what you think they are.
And to quote a bit more from the same source:
Quote
What's really interesting is that Intel has tacitly waived the 240VA limit requirement in its PSU validation program for the better part of a year. Intel maintains a web page listing all the ATX12V they have tested that "meet MINIMUM electrical, mechanical fit and functional compatibility" with Intel desktop boards and processors. For the 32 ATX12V v2.2 PSUs tested in 2005 that are on this list, 17 models are identified as having at least one output line that exceeds 240VA. And yet, these 17 models are on Intel's approved list.
According to the engineers I spoke with, the majority of these 17 models have just one 12V line. They also point out that there are another 20 or so ATX12V v2.0 PSU models on the Intel list, and none of them were tested for the 240VA current limit conformance. My sources say that if these models had been tested, more than half would not conform to the 240VA current limit because they have only one 12V line.
In the last couple of months, my PS engineering sources report, Intel has verbally informed them that the 240VA limit has been removed. A single 12V line is now "officially" approved, never mind what ATX12V v2.2 specifies.
What does all this mean? Essentially, the only potential benefit of dual 12V lines is improved safety, and this is questioned by the engineers I spoke with. There are many downsides to dual 12V lines, including higher cost and the extra headache of ensuring adequate 12V current for all the components in complex, high power systems. For the consumer who is trying to make a choice among the myriad of PSUs available on the retail market today, the most practical approach regarding dual 12V lines and power capacity is to consider only the combined 12V current capacity. (It will certainly be interesting to see how Intel handles this issue in the next version of ATX12V.)
But you better read their site, as there is way more info there regarding PSU's then any other site I know of.

Sudden shut-downs

Hallo,
I also encouter that sudden shutting-down problem on my 12" iBook 1,33 GHz PPC G4.
I've read a lot of threads in here on related stuff.
To be exact
* I had both shut-downs and display-darks, on power-supply and on batteries.
* I ran extended AHTest, it reports everything is fine.
* Power Supply colors behave ok.
* Battery does go up to 98% only. I had a replacement, it counts only 45 cycles.
* Slight tweaking or shaking the machine doesn't reproduce prob's nor help.
* Closing and opening the screen solves the display-dark issue.
So what i would like to find out is, if there is a way to tell if it's a logical board issue or a dc-in-board issue; before deciding for a replacement part or a replacement machine.
p.s. some lines quoted from system log that may tell sth:
(shutdown resetted date. reboot was at "Jan 1 02:00:33")
Jan 1 02:00:34 localhost kernel[0]: ApplePMU::CLOCK RESET! PMU WAS PROBABLY RESET SOMEHOW!
Jan 1 02:00:37 localhost kernel[0]: ApplePMU::PMU forced shutdown, cause = -127

Hey mono,
Closing and opening the screen solves the display-dark issue.
It might be that you have a reed switch problem (or an inverter cable problem more difficult to repair).
If you raise the keyboard and open up the ram shield, in front of the RAM are two connectors. The one closest to the display is the trackpad connector the other one further toward the front of that is the reed switch connector. I have a 1.33 12" logic board here and can identify the connector but since it's apart I can't tell if there's enough room in there to be able to pull that connector.
Maybe a tweezers with a long right angle tip.
In the service manual the trackpad connector has 4 blue wires and the reed switch connector has a red and black. If you can disconnect that plug that could solve your problem. The worst thing that would happen is that your iBook would not go to sleep when you close it.
So another test of the reed switch would be the next time it goes dead pass a magnet over the area just inside of the foreward edge of the CD slot about 1" to the right near the bottom of the keyboard. If that solves the problem it's most certainly the reed switch.

IMacs suddenly shuts down

Hi,
Since a while my iMac suddenly shuts down and reboots.
It starts with a frame freeze, can't move the mouse cursor. After a few seconds my iMac shuts down.
I have no idea what the problem can be.
This is the report of Console when it shuts down.

Hey MagicMarcus,
Thanks for the question. I understand that you are experiencing issues with your iMac unexpectedly shutting down or restarting. The following resource provides some great information if this happens, along with potential resolution steps if it is a reoccurring issue:

System Sudden Shut Down Problem

Hi there - not sure how to trouble shoot this so I thought I'd start here:
My system runs for a while and then will suddenly shut down by itself with no warning.... I cannot restart by pushing the power button unless I wait awhile. (few mins) Very strange, upon boot up the system does NOT go through a disk check or anything, boots up normally.
Somethings that seem to trigger the shutdown, use of websites with heavy flash components.. Mostly kids sites like disney etc...
I use Mozilla and the flash player is the latest greatest...
I know this is very vague but thought I'd throw it out to see where folks think I should start.
My 1st guess was an overheating prob.. I have a rear 80mm case fan the CPU fan and the power supply fan going full tilt... No excessive dust issues clogging fins etc...
Any thoughts much appreciated!

Hi!Just a thought..
Supposly you have an msi main board you should have the "core center" utility which shows cpu/system/nb temp's. Additionaly you can adjust the fan speed with it.
Another point is that in the past sometimes my pc used to restart without a reason. A hardware explanation is that cpu is overheated or something else went wrong. But i realized that it happend because of software..And usually when trying to run specific programs.Maybe it was drivers,maybe something unwanted installed from "bad sites", anyway try to use system restore some days before the 17th of this month just to be sure.I mean you have a quite new psu and if something was going wrong with the heatsink of cpu it would have restarted earlier during boot.
Anyway the post is 3 days long and maybe you've already managed to solve your prob.

My phone was fully charged and suddenly shut down and wont turn back on iPhone 4

my phone was fully charged and suddenly shut down and wont turn back on
iPhone 4

Hi there,
I would recommend taking a look at the troubleshooting steps for unexpected power off issues found in the article below.
iPhone: Hardware troubleshooting
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Issue not resolved
My issue is still not resolved. What do I do next?
Contact Apple Support.

My MacBook suddenly shut down and won't turn back on - how do I get it to turn back on?

My MacBook suddenly shut down after freezing up and I cannot get it to turn back on again. I tried the suggestions in the manual and none of them worked to turn it back on. Is there something I am not doing correctly? The little green light on the charger connector is green but not as bright as normal, it was charged by over 70% before it shut down, so I do not think it is a battery problem. Is there anything I can do to turn it back on? Thank you for any help given, I really appreciate it.

If it won't bong, then try an SMC reset.
