HELP!!! Computer shut off, will not restart

I have a Satellite L305-S5949 that shut off without warning. Will not start, no power indication lights with power supply attached. Completely dead, lt's like it blew a fuse or somthing.
I checked the power supply and there's 19 volts comming out which is correct.
Is it possible that the power supply fails under load and checking it with a multimeter doesn't show that?
Hope it's not the motherboard.
Any ideas?
Thanks

Hello iggy.
You do not know how many power supply sockets I have had to repair, weak part of any laptop. Try wiggling the plug in it to see if you can somehow make a contact.
Yes, the power "pluged in" LED is on its own, it should light up any time the grid is powering the machine even if it is off. Get some thin shims of metal and also check the voltage of the battery, the +&- are shown on the pack.
The socket on the MoBo is pad soldered to it and will at times let go, I have been in the habit of paralleling a wire to all the contacts to ensure integrity.

I have a macbook pro 13" 2011, When my computer boots I get code on my boot up screen and then my computer shuts off and then restarts. Its an endless loop, as my computer tries to boot up.

I have a Macbook Pro 13", that was purchased in 2010-2011. So randomly yesterday, when I boot up my computer I got to the boot screen, then code popped up on my screen. ** I have attached an image of the code below.** But after the code pops up, my computer shuts down, and tries to boot up again. This is an endless loop and doesn't get passed the boot screen. The code shows up everytime.
I personally believe this might be a software issue and not a hardware. Please feel free to shoot out any ideas or a translation of what the code is referring to.
THINGS I HAVE ALREADY DONE:
- Reset the PRAM by holding CMD+Option+P+R
- Gone into Safemode and tired to verify the Harddrive.
- Please don't comment saying, "take out the battery." , "hold the power button for.." , None of that sh#* works.
Below is three different links for the same image. (just in case, **** breaks).

What happens if you boot holding the command S keys down?
If it stays running in single user mode
try the command
fsck -fy
You could try holding the option key on bootup, to see if presents you with a startup disk however
It looks as if you need to reistall the OS.

MSI GT60-0NC laptop suddenly shut off, will not turn on again. Please help.

Hi there,
I purchased the laptop back in May 2013. Today I was using it and I just launched a game on Steam when suddenly it turned off immediately. It wouldn't boot back up again. I tried pressing down the power button for 1 minute (without AC power) and then connected the power supply and tried to boot but it would not.
It did not overheat and I opened the bottom and cleaned all the dust to be sure. The battery is fully charged. I tried booting again but it wouldn't work. I live in India and I purchased the laptop in Kuwait. Seeing that there are no MSI service centers here is worrying me. Anyone had a similar problem? Any solutions?

I just had the same problem. The power button flashes white for a sec, but nothing starts up. The disk drive wouldn't even open, so it's probably a fried motherboard. I just sent mine in for RMA, so it'll be a while before I get mine back. I live in the US though, so I don't know how you're going to get service.
Not much help from me, but sending it in is probably the best solution. As for where, well, I can't help you there.

My Nexus shut down, will not restart.

Changed out battery, nothing. Went thru troubleshooting, nothing. Plugged into computer, told I need Driver OMAP4440. From online search it appears there's no fix. Anyone?

That's terrible PaulM25! I know how important it is to have a working device! I would suggest attempting a Hard Reset. Do you have the Google Nexus 7 tablet, or the Samsung Galaxy Nexus? If this doesn't work, most likely you will need a new device. How long have you had your Nexus?
Thank you,

Mac mini shut down on its own, will not restart, grey screen, spinning wheel. Unplugged everything, will still not restart. Did safe boot, will not restart after safe boot, only grey screen with spinning wheel.

Mac mini shut down on its own. Could not restart, chime, grey screen and spinning wheel. Unplugged everything but monitor, still only chime, grey screen and spinning wheel. Started in safe boot, shut Down, will not restart.
This happened a couple of months ago, unplugged everything and it restarted, now that won't work.

Hi BDAqua,
I just did the repair as you suggested. T ran the disc repair, and twice it cam back, the volume macintosh seems ti be okay, I also ran the verify and permissions repair, both came back okay.
I was actually hoping that they would find something, so they could repair. I shut the computer down, and restated with out holding a key, and I started up great. I'm baffled. I have moved 20 GB to an external hard drive, as I only had 10% open space.
I have Tech Tool 6, would you recommend to run a repair check on that, or just leave well enough alone.
I agree with you on the new Mac's, I have problems with no disc for back up, until they realize their mistake I will stay with Snow a Leopard. This is the first problem I have experienced, so I can't complain. Their last programs are not as perfected as under Steve, prior to his handling over the reins, hope this is not going to be the future we can expect from Apple.
I will wait to here back as to your suggestion regarding the Tech Tool check
Thanks for all your help.
Gratefully,
Cheri

My iPod 5th gen will not completely turn on it shows the apple symbol then shuts off I have restarted it and tried to plug it into my computer but cannot find it to restart it
Its been like this for awhile and I can not fix it

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Please Help.

Hello and welcome!
It sounds like it has a hard ware reason. I suggest you take the motherboard out, to see that there are no stand-offs/spacers/distanser left unused creating a short.
Also, remember to have as little hardware as possible when you install Windows. No extra PCI-cards, USB-devices and such.
If the system has worked well earlier, above still rules, but here are some many other reasons for the described symtoms:

I am trying to load my library on the new computer but it will not let me import. the shared library disappears when i shut the original computer off.

I am trying to load my library on the new computer but it will not let me import. when i shut off the old computer the shared library disappears.

Yeah... that's exactly the way it is supposed to work. Sharing the library does not move it anywhere.
To move the library to the new computer, copy the entire iTunes folder from the old computer to the new computer.

"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
Repair both Disks.
Also, In Finder's Menu, select Go menu>Go to Folder, and go to "/volumes". (without the quotes)
Volumes is where an alias to your hard drive ("/" at boot) is placed at startup, and where all the "mount points" for auxiliary drives are created for you to access them. This folder is normally hidden from view.
Drives with an extra 1 on the end have a side-effect of mounting a drive with the same name as the system already think exists. Try trashing the duplicates with a 1 or 2 if there are no real files in them, and reboot.
If it does contain data...

July 18,2011 AOL toolbar update install. I cannot open Firefox to uninstall the update or the toolbar because everytime I open Firefox it freezes and jams up. I have to shut down my computer as it will not even respond to force quit command

July 18,2011 AOL toolbar update install. I cannot open Firefox to uninstall the update or the toolbar because everytime I open Firefox it freezes and jams up. I have to shut down my computer as it will not even respond to force quit command. I cannot read my mail (aol) or access my bookmarks all for work.

Try the Firefox SafeMode. <br />
''A troubleshooting mode, which disables most Add-ons.'' <br />
''(If you're not using it, switch to the Default Theme.)''
# You can open the Firefox 4/5/6/7 SafeMode by holding the '''Shft''' key when you use the Firefox desktop or Start menu shortcut.
# Or use the Help menu item, click on '''Restart with Add-ons Disabled...''' while Firefox is running. <br />
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.''
You should be able to uninstall that AOL toolbar extension while running in the Firefox SafeMode.

I have an iMac that I am running OSX 10.8.3 on. I keep trying to install 10.8.4 but it will not install. I tried updating and installing several times and it restarts the computer but it will not install the software. My machine is about 8 months old.

Sometimes the App Store version doesn't work correctly. In this case, install 10.8.4 with the Combo version > http://support.apple.com/kb/DL1659?viewlocale=en_US&locale=en_US
The Combo installer is the safest way to update OS X, and it allows you to update more than one computer with a single download
