    iMac won't turn. Startup disk is full. TDM won't let me edit.

    My iMac turns off 10 seconds after the start to the top. I tried repair disk running, to no avail. What is happening is because my boot drive is full, off the 500 GB I partitioned in mac, 493,63 GB is taken up. I bought a thunderbolt cable to access the TOC on my mac book, and I have access to my files now. The problem is that I can only copy files. Authorities say I read and write permissions. When I start my host computer, it says "you can still open or copy the files on the disk, but you cannot save changes to the files on the disc. Back up the disk and reformat it as soon as you can. "I'm trying to copy all my files on this computer and remove what I don't want copies, then reinstall OSX on my iMac. The problem is that some files are native to all OSX, so it would prevent me from copying the files. For example, if I want to copy my applications folder, it stops to copy once it reached the app store, because it cannot copy that. It is a problem because when it comes to the library, there are small files in there that I don't know if I can copy, then it stops at the copy and I end up with half of my files and I don't know what I need and what I have.

    Everything you need to copy the disk, then start the iMac in recovery (command-R) mode. Wipe the drive and reinstall OS X from the recovery console.

    ===============================
    I don't know what is causing this problem but would be
    suspicious, it is related to a corrupted or obsolete
    video driver.

    Might be interesting to try to reduce your graphics

    How to put in back of graphics hardware acceleration
    http://www.pptfaq.com/FAQ00129_How_to_set_graphics_hardware_acceleration_back.htm
    (scroll down to: "If you are using Windows 2000 or XP")

    If they improve the question, you should look for the
    site Web of MFG. your video card
    a updated driver Win XP compatible video. Or...
    If your computer is a laptop... Search support
    site of the manufacturer of your computer.

    If you do not know the make and model of your
    Video adapter, see the documentation that
    supplied with the computer.

    Also you can find info on your video by driver
    go to Device Manager: you can launch
    By clicking Device Manager on... Start/run and
    type or copy / paste:
    devmgmt.msc
    And then press ENTER.

    Expand "Graphics cards" and right click
    the name of your graphics... then
    choose... Properties / tab pilot... FYI.

    You should find the make and model of your
    adapter display as well as the version of the driver.

    If the driver on the Web site is no longer
    current than you run...
    Download and install it. In addition, installation
    instructions that should be followed closely
    should be available on the support site.

    Once installed the new video driver... you
    can restore your full acceleration.

    Good luck...

  • Screen won't turn on and can run Vista in safe mode on Satellite P series

    Last night, I was working on a slide show with windows movie maker in Vista. I had trouble getting the software to recognize my video files for my camcorder, so I suggested that I try to download codec so that he could play my files... I don't know what I was doing, but he gave a shot.

    Even if the codec didn't work even after the download, I was still able to run my computer normally. This morning I woke up and continued to work on my slide show but my computer wouldn't play my slideshow. All he would do was play music and audio files... Everything seems to be working so I decided to restart it.

    My computer will restart, but now my screen is black. It remains 'functions' I see change different colors of black and gray because it is set to zero... and I can hear all the audio that comes with reset, but I can't get my laptop screen to work.

    I plugged my desktop monitor to my laptop to see if the monitor would work like that and it did for about 30 seconds, then turned off Black too. I then rebooted and press F8 and ran in safe mode with my always-connected desktop monitor. I am able to run in safe mode but not normally reboot. I think I downloaded some viruses with this codec.

    I decided to get the desktop monitor and press F8 just hoping the screen would show up on my laptop... but it still doesn't work. It stays black.

    Now, I'm running in network mode so I can know what to do next. I tried a restore of the system in safe mode, but I think that it only deleted windows updates and not something else. I can't find my toshiba recovery CD because we moved a month ago and it's somewhere in a box...

    So here I am. I work constantly on a slide show for Christmas and can't play or it end before my laptop works again. I also tried a during restart System Restore but I don't know my password of administrator and I tried a couple that I thought that I would have used during installation, but they were not good and so now he me off to run as administrator.

    Can someone tell me what I can do? Thank you very much

    I'm a newbie here, but have you tried...

    1. press F8 (press on and hold, or press repeatedly) while Vista boots, and then select Safe Mode. This should automatically open the account administrator (no password needed) and you can then reset your existing account to the administrator.

    2. simply delete all user accounts permits (including the one you are logged as) without forgetting to let the disabled administrator account. And then disconnect.

    3. use Offline NT Password & Registry Editor to unlock the administrator account or promote another user to the local Administrators group to regain access to your locked Windows Vista PC.

    4. also Vista has a hidden superuser account.

    Just my 2 cents.

  • BlackBerry Smartphones Blackberry Bold 9700 won't turn on and keeps restarting!

    I only got my Blackberry "BOLD" for about 2 months. The camera was a little funny and don't zoom so I turned my phone off and took out the battery and succeeded him in an attempt to restart the phone. Now, it won't turn!

    When the battery is in the light of the red LED at the top right corner turns on then turns off when the phone starts showing the BLACKBERRY Logo on the screen with the loading bar under. The bar then shows it to load, but almost immediately, it freezes and turns off. She does several times, but I tried to remove and replace the battery several times.

    I'm sure that this is not a problem with the battery, I had only he alleged the night previous and even tried using another battery of my friends BlackBerry to check, but the continuous phone to turn on several occasions, crash, turn off.

    Anyone have a similar problem or know a solution? Thank you!

    Hey guys!

    I managed to fix my blackberry!

    The best and probably the only solution for a blackberry caught in a never-ending cycle of reset / or always show error messages is to perform a "Clean Reload of your Blackberry Device Software"!

    I found 2 websites more useful!

    This site is by Blackberry from Research in Motion themselves who teaches you how to perform a clean reload. It requires for you to have your cable USB Blackberry and Blackberry Manager installed on your computer. There is a clear process of no to no! However, there are some which confused me at first so just to clarify... in step 4 where they ask allows you to check that you don't have the latest version of the software installed... If your software device tab is empty as indicated in step 3, this means that you currently no. SOFTWARE INSTALLED and so should follow the link indicated in step 4 (or pasted below) to download (and install) the latest software for your blackberry phone model and service provider before performing a cleaning charge.

    For a clean reload:

    http://www.BlackBerry.com/BTSC/search.do?cmd=displayKC&docType=kc&externalId=KB11320

    To download the latest version of the device software:

    http://www.BlackBerry.com/BTSC/search.do?cmd=displayKC&docType=kc&externalId=KB12532

    NOTE: When you do a clean refill, you can see that the Blackberry Manager to first show your blackberry as "disconnected." If the Manager continues to install/reload the software for device on your blackberry with no complications, I wouldn't worry too much about not because once the own recharge is over and your device will restart the Blackberry Manager would show so your device as "connected."

    ------------------------------------------------------------------------------------------------------------------------------------------

    The second site (unofficial Blackberry Forum) basically explains / uses the same process but it is a little outdated and I found some differences in the Blackberry Manager software they use and some steps may no longer apply. However, it should be that if you find you have difficulty getting your BlackBerry connected to your Office Manager as constant rebooting CAN cause the device to connect and disconnect continuously, this site can be useful for more of this problem. I personally don't have this problem if I had expected, which can be a result of the latest models of Blackberry devices and software device etc.

    For more of the constant connecting and disconnecting your BlackBerry since the Blackberry Desktop Manager:

  • Satellite C660 - 23 M won't turn on and makes a high pitched noise high

    Hi I'm new here

    Ive had my laptop for about 2 years and she had a lot of problems - broken screens, dust in the fan, etc.

    yesterday I used it as usual when it off completely without warning.
    I'm used to is happening because my laptop overheats and turns off like that on a regular basis.

    However, when I turned it back on, it makes a high pitched noise that kept getting more high until the laptop turns off again.
    I think the noise of the fan.

    There was also a slight smell of burning plastic.
    My laptop does not turn on and when I plug it in the orange power light does.

    To be honest, all the details do not sound very good...
    Everything looks like some causes of serious hardware problem laptop cannot be turned on.
    I can't say for sure what the problem is here, but probably the motherboard or the CPU is dead.

    In any case, your data on the HARD drive should not be affected, and I guess you could get access to your entire iTunes library. You must remove the laptop HARD drive Bay HARD drive and you will have to use an external USB 2.5 "HDD caddy to connect the HARD drive from the laptop to another computer as an external USB HDD.

    This will allow you to move forward and back up the data to another job good HARD drive.

  • My e280 won't turn on and is not recognized by my computer

    A while ago, I add me new music to my 8GB e280 version 2. I didn't know that the space was needed for a database, so I continued to add and Add. I thought that if I could not add more, a pop-up message box and tell me that I had no more space. I was being followed to make sure that I had less than 8 GB here. I finished and unplugged the USB cable. The login screen shifted so I had just the power button until it turns off and I turned it back. He said no "enough space for music DB. Please free 90 MB. "So, I immediately hooked the USB cable to my sansa and the computer. However, the computer would not detect my sansa. I got it on an automatic mode instead of MTP and MSC mode. No matter how many times I tried, my computer just would not sense. So I can't reformat my computer. I can't turn on my sansa, because when I do, it shows me the splash screen, then the same message "not enough space for music DB. Please free 90 MB' and then immediately closes upward. I can't change the mode and manually delete the files.

    I'm in trouble real here. I can't use my sansa at all. If you know what to do, help me please!

    Too bad. After reading a lot of posts here, I learned how Force MSC mode. After pushing left and plug the USB for the gazillionth time (seriously, my fingers are sore from pressing on so much), I was able to find my sansa and I reformatted. Thanks a lot guys! I am very grateful for this forum because without it, I could always be panic on my sansa died. I will follow this in the case where another mess up someone as bad as I did.

  • BlackBerry Smartphones Please help - my phone keeps restarting/reloading. It won't turn on, and I need to access my calendar to see if I need night tonight or tom meds

    Hello, I hope someone can help me. I have medication alerts on my phone, without it I don't know if I need my meds tonight or tomorrow night.

    I downloaded a few free apps now in app world for blackberry on my phone as I have done several times before.

    He asked a reboot once completed. so I clicked to restart. Since that time (4 + hrs) sound was reloading all the time, it is right at the end and restarts it again without turning on

    I removed the battery and tried to turn it on, it does the same thing. I tried a reboot after removing the card and sim, then both and still nothing.

    I also tried to boot in SafeMode by hiolding down the ESC key but it dosnt work.

    Help, please

    You are able to reboot your device in SafeMode as shown in KB17877?

    This could remove some data if you do not have a current backup

    I guess, because it is taken in a reboot cycle, when you connect to the desktop software it does not have a stable connection to reinstall your software?

    If this is the case, remove the battery and keep it off when you connect to the desktop software. You will get a pop up that the device cannot connect and there should be buttons retry, update and cancel. Select Update and you will then be able to reinstall the latest version of the device software.

    When the load progresses, you will see a step that says "waiting for initialization of the devices '. At this point, insert the battery and recharging must complete.

  • Just paid for Acrobat XI and it won't turn on and start working.
