Computer randomly shuts down and refuses to boot
Hello all.
A while back I installed Win 7 Pro on this (I think I had to install it on an SSD via another machine then used that SSD in the T610 and used win repair to fix the installation).
It's been going smoothly generally and it is on mor or less 24/7 for light use. I use it for watching films and browsing the net. nothing uch more intensive. Ever since the start, I would come in the morning and find it had shu itself down. sometimes when I push the power button it would boot back up as if everything had sut down properl. Other times when I push the power button its backlight stays on but I get no activity. Even the HDD light does not flicker. I also cannot repeat the trial unless I disconnect the power cable because holding the power button for any length of time does not switch off the system*
Sometimes I have some success if I open the case, reconnect the SSD and push the power button again but that is rare.
I don't think it's overheating because sometimes I leave the machine off for 12 hours and it still refuses to boot for another few hours.
It's really frustrating and I'm not sure what to do as even if I disconnect the SSD and push the power button in it's "sulking" state I get no feedback; bios nor sounds.
Could my BIOS be faulty? How do I check/update it's version from within windows? Often I don't see the bios screen. I remember I used to see it a long time ago but now it does not appear.
*The only time I have seen the PC turn off after holding the power button is if I am in Windows repair mode for some reason.
Thanks in advance for any assistance.

My computer randomly shuts down and won't restart.
My computer randomly shut down and would not restart. I took it to an apple store and they fixed it by running something through the disk utility. I was told to run something else (it had to do with what the computer does when it shuts down as I don't shut mine down a lot). It had been running when the guy showed me it at the upper right corner and said "initializing" but I did not remember what it was called when I got home and it was no longer open. Any one have a similar problem where this was suggested and remembers what is it called?
Try a SMC reset.

Computer randomly shuts down and...
Hello everyone!
I have had my desktop for about 7 months now, and haven't had any problems. Recently, my computer had begun to make a (sort of) loud humming noise. The humming noise would get louder at times, then soften back to a slight hum.
It has been doing this for about 3 weeks, but I didn't think anything of it because the performance of my computer never changed.
However, just a couple of days ago, when I was in the middle of a game (League of Legends,) my computer shut off when a lot of "action" started going on in-game. I tried to turn it back on, but only the fan and lights came on for 2-3 seconds, and it would shut back off.
I did some research and figured it was just dusty in the case, so I cleaned it out. That doesn't seem to be the problem, however the humming sound did stop. :/
I am thinking the PSU now, but I was wanting to know everyone else's opinions before I did anything.
My computer is under warranty still, thankfully. But I probably want to upgrade the PSU if that is the problem.
Here is my computer: http://www.bestbuy.com/site/CyberPowerPC+-+Gamer+Ultra+Desktop+-+8GB+Memory+-+1TB+Hard+Drive/6897999...Humming, in my experience, is usually from the power supply, but it could also be a faulty CPU cooling system.
I would take it into a store and have a Geek Squad agent check it in for a diagnostic(free under warranty) to nail down what is causing the problem.
The PSU would be covered under warranty, but an upgrade would not, so that's your perogative if you decide to upgrade.
Any other hardware issues should also be covered under the warranty.
If you like my post, or solution to your issue/question, go ahead and click on the little star by my name and/or accept the post as the Solution. It makes me happy.
I'm NOT an employee of Best Buy, or Geek Squad, though I did work as an Agent for a year 5 years ago. None of my posts are to be taken as the official stance that Best Buy will take on your situation. My advice is just that, advice.
Unfortunately, that's the bad luck of any electronic, there's going to be bad Apples... wait that's a horrible pun. -
Mid 2010 15" Macbook Pro Random Shut down and Restart
I know this questions have more than likely come up a few times. But I have a mid 2010 15" Macbook pro that, for the last year, has randomly shut-down and restated displaying an error message each time. I have had this computer into three different computer repair shops over the last few months, two of which were apple certified, and have had a range of reasons provided for the issue. Anything from Motherboard to hard drive to virus. I have replaced the hard drive, did a complete reformat three times, and downgraded my OSX. But I still have the same issue. I recently came across some support tickets referring to an issue with this model of Mac, something to do with the graphics card. I downloaded a program that was supposed to be a work around, but am still having shutdown issues. I also heard that apple did a free replacement of the motherboard on these machines within 3 yeas of purchase. Obviously I am past that point, but I was hoping that there would be some other suggestions. I have ran an etrecheck on my machine and have attached it below. Can anyone provided any ideas of how I can fix this without having to buy a new motherboard?
Thanks for the help...
Cheers,

Macbook Pro Randomly Shuts Down and Restarts
Hi There,
This issue appears to have occured for other people in different forms but there does not appear to have been a conclusive answer to the problem, so here's hoping someone here might be able to provide some further insight into the issue, and with some luck, a solution.
I have an early 2008 MacBook Pro running OS X 10.7.2 (plugged-in to power) that has started to randomly shut down and then restart itself (goes through all the start up screens; Apple logo etc.). It doesn't appear to be just a straight restart of the machine, but it shuts down, and then a couple of seconds later, reboots, as though it is two different actions...
The computer does this pretty randomly, and now quite often. It happens when applications are running, Safari for example, and when nothing is running and i just go to open Finder or use Spotlight.
I haven't had this issue in the past (some 3+ years of full time use now) and as far as i'm aware, nothing changed on the computer immediately prior to the issue occuring (no updates, installs etc.).
I've checked the systen log which, each time the issue occurs, returns the message 'Previous Shutdown Cause: -128'. I've sought reference as to what this refers to, but it would appear to be a mystery to the WWW.
I have tried the following solutions with no success:
- Proper restart and reboot of system;
- Repair permissions;
- Reset SMC;
- Reinstall OS X.
Any thoughts on what the problem is, what the '-128' refers to, or what more i can try to solve the issue?
Your help is much appreciated! Thanks.I know this is a really old thread, and everyone's probably already bought new computers now. However, I'm still using my 2010 MacBook Pro and have been experiencing this very frustrating issue. However, I think I just found a way to open a finder window that prevents the shut down. In Finder>Preferences>General, under "New Finder windows show", I had "All my files" selected (BAD?), which probably was the cause, because setting that to "Desktop" instead has prevented shut downs, for now. Just thought I should share this tip, in case anyone else suffers from this annoying issue. If anyone has a better tip or a real fix, please post a reply! There are still people, like myself, working on these older machines who would appreciate the info. THANKS!

MacBook randomly shut down, and won't turn back on
First of all, hello. Secondly, I've got a problem with my MacBook: about half an hour ago, it randomly shut down and when I tried to turn it back on, it didn't. Instead, the backlight kept flickering at the tempo that something inside the computer was "clicking", and the longer I held the power button, the more "clicks" there were. Needless to say, I've tried charging the battery, resetting the SMC, and to no avail: I still can't power it up, even when I don't use my battery. Whether I use it or not, the MacBook still "clicks" during my pressing of the power button and stops "clicking" when I release it. My MacBook is a year old. Can someone help me out here?
Me too. Any resolution? I don't want to take it to my local apple place because they're retards, but according to the info on my warranty that's the only place available. Can't believe they don't have an RMA service direct to Cupertino, what a joke.

My Macbook Pro just randomly shuts down and I have to plug it into power to be able to turn it back on. Anybody got any suggestions?
Troubleshooting: My computer won't turn on
Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset. Read all the steps.
Before Resetting the SMC
Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
Press Command + Option + Escape to force quit any application that is not responding.
Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
Resetting the SMC on portables with a battery you should not remove on your own
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer. -
Since installing OSX 10, my iMac randomly shuts down and restarts. I can not determine why this is happening. Any ideas?
1. This is a comment on what you should and should not do to protect yourself from malicious software ("malware") that circulates on the Internet. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
If you find this comment too long or too technical, read only sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
For the reasons given above, App Store products, and other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandboxing security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. The built-in security features of OS X reduce the risk of malware attack, but they're not absolute protection. The first and best line of defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you always stay within a safe harbor of computing practices. How do you know what is safe?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is unsafe.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders" are outside the safe harbor, though not all are necessarily harmful.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe. For instance, if a web page warns you that Flash is out of date, do not follow an offered link to an update. Go to the Adobe website to download it, if you need it at all.
Even signed applications, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
"FREE WI-FI !!!" networks in public places are unsafe unless you can verify that the network is not a trap (which you probably can't.) Even then, do not download any software or transmit any private information while connected to such a network, regardless of where it seems to come from or go to.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. If you need to be able to detect Windows malware in your files, use one of the free anti-virus products in the Mac App Store — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. Most of the real danger comes from highly targeted "zero-day" attacks that are not yet recognized.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
8. An anti-malware product from the App Store, such as "ClamXav," doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An anti-virus app is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
Anti-virus software may be able to tell you which particular trojan it is, but do you care? In practice, there's seldom a reason to use the software unless an institutional policy requires it.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither should you assume that you will always be safe from exploitation, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices. -
Why is my macbook pro randomly shutting down and restarting?
My macbook pro is randomly shutting down and restarting. It started a couple days ago and seems to happen completely randomly. I did a extended hardware test and no problems were found. I reset the SMC and that didn’t work. Battery is charged and I don’t think its overheating. Im using Mavericks 10.9.1. Someone please help because I can’t even use my mac for anything lately and its really annoying.
If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time after you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V). Please include the BOOT_TIME message at the end of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post any other kind of report — it will be very long and not helpful. -
my computer recently shut down and all of my itunes was lost. My ipad still has all of my songs on it. How can i download all of my music onto my new itunes. would i need a different acount?
You should be able to:
Backup the device to the new installation
Transfer your purchases into a newly authorized library
Recover any other media using third party tools as suggested in this post from forum regular Zevoneer
Restore the device from the backup
This process should switch the association of the device to the new library, preserving the data and settings in your apps.
May also be prudent to attempt a backup to iCloud directly from the device before you start... Settings > iCloud > Storage & Backup > iCloud Backup > On. It won't save any media but it would preserve the general account settings and documents in case anything goes wrong while you are trying to extract your other data.
When you get it all fixed, make a backup!

When unplugged my MBP randomly shuts down and won't start up again
When my MBP is unplugged it randomly shuts off and won't restart. To get it to boot up again I have to plug it in.
Today I was using my computer for about 15 minutes unplugged and it just shut down by itself. I was right in the middle of typing something and it just cut out. The other weird thing is I don't get a low battery warning, nothing, it just shuts down.
Then I press the power button to restart and I get nothing. Even when I pull the battery out and put it back in nothing. I pressed the battery level button and it blinked rapidly on the lowest 2 lights. Keep in mind I was using my computer unplugged for only 15 minutes immediately after unplugging it from the wall after it had been charing for 15+ hours.
This makes no sense. Please help me.
-JacobSounds like a bad battery and/or problem with the PMU (power management unit) and/or memory.
"Half the start up sound" is a bad sign as it means it's failing the normal start up tests (I'd guess a Memory problem)
Reset the PMU and run the Hardware tests from Install DVD1 (hold down d at startup) and see what it reports. -
My computer keeps shutting down and I don't know what to do.
I purchased the student/ teacher version of the cloud membership/ design suite for os x and promptly began downloading the programs that I would use onto my macbook pro. I downloaded photoshop cs6, Bridge, Illustrator, and Acrabat. I havn't used anything but photoshop so far but I have encountered a serious problem. When I first got photoshop I would leave the application open by accedent and my computer started shutting down randomly but only about once a day. As I started using photoshop more I started closing the application when I wasn't using it but when I was the computer would shut down at some point during each project. I could deal with saving a lot as I go but now it shuts emediately every time so I can't use photoshop at all. Please can someone give me some advice, even if it is just to go to the apple store.
I had very similar behaviour occur when I purchased my first MacBrook Pro and it turned out to be a faulty Graphics Card. Take it to the Genius Bar and see what they have to say. If they don't know what's going and it's not a hardware issue, then we need to know a lot more to help you.
