Satellite Pro U400-13D shuts down repeatedly

Hi everyone,
I'm using the Satellite Pro U400-13D for office work only. During the last days the Notebook shuts itself down without warning during normal operation.
After a restart the problem reoccurs after a random duration.
Is this problem known? What can I do about it?
Thanks,
Alexander Lorenz

Hi Alexander!
First of all welcome in forum! :)
Regarding your issue I have one question: Can you notice that the notebook is getting hot on the bottom side? I ask this because normally a notebook shuts down if its getting to hot and so it protects the hardware. Otherwise the hardware would be damaged due a higher internal temperature.
As Akuma said you buy compressed air spray. So you can clean the notebook and this blows the dust out from the cooling ventilators. Maybe it works for you.
Furthermore about cleaning a notebook I have founded an interesting article:

Satellite Pro L300D-20R shutting down in safe mode

Hi folks,
I occasionally run full scans using Avira antivirus and Asquared free as well as Ccleaner in safe mode. However, when I boot in to safe mode the fan runs aggressively all the time and then my laptop shuts down. This occurred also when I was using the help facility so is not just confined to running the anti malware scans. I tried using "start up repair" but this did n't fix it. Then I used the Toshiba HDD recovery to restore it back to the factory settings but this did n't work either. In normal mode it scans virus and anti malware free and runs OK.
Any advice appreciated.

Hi
According to your message the notebook work great in normal mode but does not work properly in safe mode. Right?
Well, since only some essential and necessary services would be loaded in safe mode, I think the issues could be related to software/system problem.
I wonder why the HDD recovery didnt function hmm you should create a recovery disk using the preinstalled software called Toshiba Recovery disk creator.
Then you could use this disk in order to recover the notebook once again.
Then you can check the safe mode functionality is you need it.

Mac book pro mid 2009 shuts down after a few hour then will only boot after waiting and pressing power button numerous times. I am running mountain lion with most recent updates.

Mac book pro mid 2009 shuts down after a few hour of use and then is very difficult to reboot. Sometimes I have to wait hours, sometimes I have to repeatedly press the power button and then it will slowly start a little longer each press untill it completely boots. It has done this three times know. Each time I was watching a video.

Try running the Apple Hardware Test - sounds as if you've hardware issues.

MacBook Pro will not shut down properly

MacBook Pro will not shut down properly. Gray screen appears with spinning gear but will not shut down completely.

If you have more than one user account, these instructions must be carried out as an administrator.
If you have an optical drive, make sure there is no disc in it.
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.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.
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.
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 when you had the problem. Post the messages logged during the time something abnormal was happening. That time might be before or after the boot.
For example, if the problem is a slow startup taking three minutes, post the messages timestamped within three minutes after the boot time, not before. If the problem is a system crash or shutdown failure, post the messages from before the boot time, when the system was about to crash or was failing to shut down. In either case, please include the BOOT_TIME message at the beginning or the end of the log extract.
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post 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 shutdownStall or hang logs — they're very long and not helpful.

After updating my software from snow leapord to mountain lion my MacBook Pro suddenly keeps shutting down without any reason no warning suddenly just restarts... Can someone help

After updating my software from snow leapord to mountain lion my MacBook Pro suddenly keeps shutting down without any reason no warning suddenly just restarts... Can someone hel

Note the date and time the problem occurred, then go to Applications/Utilities/Console and copy the log starting at the time of the crash. Paste the log in a reply. Please do not use a screen shot as they can be hard to read. If there are repeated runs of the same messages, please post only one run. Be selective about what you post and don’t post huge amounts. Make sure there is no personal data visible. Information learned from Linc Davis.

As soon as video touches my Source or Program windows the Mac Pro (3,1) shuts down

Linc,
You keep showing up when I search for this problem so I hope you can help.
I'm having the same issue in Premiere and Media Encoder (but not After Effects). My Mac just restarts itself as soon as video is loaded. I can start Premiere and open a project and go through relinking media, but as soon as video touches my Source or Program windows the Mac Pro (3,1) shuts down.
I've fixed the problem temporarily two times. The first time I was troubleshooting what was wrong and wound up putting in my old video card and after that fixed the problem, I switched back to my GTX 680. I also did a driver update. After doing that I was ok for a few days so I figured it was a driver thing or maybe the card just needed to be reseated. Then when it started acting up again I figured something was going on.
So I started searching again and came across one of your posts that recommended removing CUDA. I did that and it worked perfectly for a week until about 20 minutes ago. Crashed in the middle of an edit and now each time I restart Premiere it crashes as soon as video touches my monitors.
I found this post because I specifically searched for "com.nvidia.web.NVDAResmanWeb(8.2.7)" from my Problem Report.
Any thoughts?
Thanks,
Darren

Thanks for the reply. Sorry for the shortened log. Here's the full thing. By the way, where do you learn to read these things? Are there keywords like "error" that you just learn to look for or is it something for in depth?
Thanks,

My Macbook Pro won't shut down or restart without forcing shut down. Hangs on grey screen. iTunes not recognizing iPod.

HELP!!!
Here are the specs of my machine:
2011 13.3" MacBook Pro
4 GB Ram/320 GB HD
For the past several months my MacBook Pro refuses to shut down or restart without holding down the power button. Whenever I choose to restart or shut down the computer, it will hang on a grey screen. I have even tried letting it hang for an hour, and it still won't shut down. I notice that once in a while it will retart or shut down correctly if I had not used opened iTunes since turning it on. However, even manually closing iTunes before shutting down or restarting does not solve the problem. It seems as though it only shuts down if iTunes was not used since restarting the computer. Is this a registry error? Do I need to reinstall iTunes? I noticed this problem began happening after I uninstalled Kaspersky Virus Scanner, could that be the problem as well? Also, I cannot guarantee that the problem is only associated with iTunes. I just noticed that one of the few times it shut down or restarted correctly, iTunes coincidentally had not been used. Also, this problem started happening while I was still using Lion and has continued despite upgrading to Mountain Lion.
Also, whenever I update my iPod through iTunes, it won't eject properly, and a transparent icon of the iPod displays on the screen even after I have removed it from the USB port. Furthermore, the iPod will only be recognized by iTunes and will only be updated the first time I plug it in. After removing it and plugging it back in, it won't recognize or update the device unless I shut down and restart the computer. I have the latest addition of iTunes. I also have two iPods, one 80 GB Classic, and one 8 GB Nano, and I have the same problem with both.
I have AppleCare. Should I take my macbook to the genius bar?
Applications I normally use are Word, Safari, FireFox, iTunes, FinalDraft, Photo Booth, Notes, Mail, App Store, etc. No real heavy lifting.
Any feedback would be very much appreciated. :-)
Thank you everyone!!

I have this question too.

Satellite Pro U400-G13 - "C++ Runtime Error" on startup

Hey Toshiba Forum Users
I just bought a Satellite Pro U400-G13
I powered it up and the auto install startet Windows Vista. The computer restartet.
After reboot a toshiba program starts up and requested a reboot more.
After that I have a "C + + Runtime Libery Error" every time I start the computer.
If I press OK the screen goes to black in 1 secound and the error shows up again.
It comes up in a "Please Wait" screen before the login screen to Windows.
I can start it in Safe Mode but do not really know what I should do with that...
Is there anyone who has tried something similar or has any good ideas for what I can do ..
Many greetings Asger Benzon

Hi
Try to reinstall the preinstalled OS using the HDD recovery option;
Like Raver said you can press the F8 button immediately after the notebook has been powered up. Then choose repair my computer and star the Toshiba Recovery procedure.
This should start the new OS installation.
After the installation has finished, reboot once again and check the OS again for any error messages.
Bye

MacBook Pro will not shut down

A principal at my district has a MacBook Pro 15-inch Early 2008 (2.4/2X1GB/200-5400/256VRAM/AG) running OS 10.5.8 that will not shut down. When shut down is chosen, the computer restarts instead of shutting down. It does not matter how shut down is chosen, whether it is from pull down menu, keyboard command, click on shutdown in the login menu, etc. I have tried resetting PRAM, SMC, starting up from a known good system, and run diagnostics applications (which turn up no problems). The only way to get the machine to tunr off is hold the power button down until it shuts off.
The user complains it also gets very hot when he leaves it sitting open in sleep mode. I have not observed that particular symptom. It also tend to run down the battery faster than it should (battery check shows it to have 80+% of it's original capacity.) But Activity Monitor does not show any unusual activity.
Any suggestions what I can try next to figure this thing out?
Thanks.

On occassion (like tonight) my MacBook Pro will not
shut down - even when I attempt to force quit. Any
suggestions?
Happens here too, but very rarely. In my case it mostly happens late at night when OS X is supposed to run some internal maintenance jobs, maybe some of them do not allow a shutdown?
Does holding the power button down for approx. 10 seconds work? If yes, then I would not worry about it. If no, there is something seriously odd and I would report it to AppleCare.
Cheers,
Uwe

I??ve got a U400 which was equipped with the Intel graphic card and I??ve got an external LCD which I have connected to the U400 using the DVI-to-HDMI cable.
My U400 unit supports the HDMI and the LCD the DVI port.
I have received also the driver disk with my LCD and I have installed the software.
I have also update the Intel driver and used one from the Intel page.
Now I have the access to many different external resolutions and can choose it.

Mac book pro trys to shut down while downloading?

my mac book pro trys to shut down while im downloading for some reason..

Hi Monroeeugene,
I'm not sure if you mean shutting down or going to sleep ... but this article will explain how to change your sleep settings so your downloads don't get interrupted.
Mac Basics: Set your preferences
http://support.apple.com/kb/ht2490
Change your Mac's sleep settings
To conserve energy, all Macs have the ability to sleep. When you haven't used your Mac for a set amount of time, it enters a low-power mode until you wake it by pressing the keyboard, trackpad, or moving the mouse. Sleep doesn't turn off your computer; it merely puts it into an inactive state that consumes less power.
Open System Preferences
Choose View > Energy Saver.
Choose the Power Adapter or Battery tab. If you're using a desktop Mac (a Mac mini, iMac, or Mac Pro), the Power Adapter and Battery tabs do not appear.
Move the sliders for both the computer and display to change the times in which they go to sleep.
Select any other options you want, such as sleep and wake.
Hope this helps ...

DVD Studio Pro continues to shut down unexpectedly

I have an iMac running Mac OS 10 and my DVD studio Pro continues to shut down whenever I try to open a project. I have no idea how to start fixing this problem and have not found any other forums to be of help. I have a 2 GHz Intel core duo processor with 2 GB 667 MHz DDR2 SDRAM.

Hi:
What version of DVDSP are you running? You need at least DVDSP 4.1 to run under Intel processors.
You can try this DVDSP: TROUBLESHOOTING BASICS

Have you tried holding the power button down for several seconds? I would try the force quit as mentioned earlier first, or go to the Activity Monitor in Applications>Utilities and try force quit there.
