Toshiba screen power failure that cannot be repaired

My Toshiba Satellite laptop has a problem turning on. The screen is completely black but the fan turns on, light, charger works. I checked the Rams, neither would work alone or together. I don't know what this means or what to do next. I appreciate any help that can be given.

Hello

Did you do something that might be responsible for this? Update the BIOS maybe?

  • Scan of found corrupt files that cannot be repaired by SFC

    After problems with a recent update of windows which was followed by a restore failed, a black screen, then a system repair, I now have a number of corrupt dll files which result in "bad image" error messages when I start applications.

  • System File Checker detects files from oembios that cannot be repaired

    I ran the System File Checker on my computer Dell Dimension, and he found files that cannot be repaired: oembios.dat, oembios.sig and oembios.bin. The computer has Windows XP with Service Pack 3 installed and was purchased new in December 2002. The original XP installation disk that I've ever used, a SP1 is installed.

    Event Viewer gave this message for one of these files after run the System File Checker. "The oembios.sig of file protected system could not be restored to its original, valid version. "The file version of the bad file is 0.0.0.1 the specific error code is 0x800b0100 [no signature was present in the subject.]."

    Everything works well, and these corrupted files seem to have no effect on the operation of the computer. I even ran a Seagate hard drive diagnostic test, and it passed. These files, compressed copies that are in c:\i386 and on the installation disc, be repaired and properly placed in their place in c:\Windows\System32?

    Thank you, Robert. I tried your suggested solutions.

    First, I tried expanding oembios.si_ of the CD on the e drive (CD player) after the reboot. But I got this message from the command prompt: "cannot open the input e:oembios.si_ file."

    Second, I tried to develop oembios.si_ of the c drive, where I know it exists in c:\i386. Yet once again, I got the same message that the input file cannot be opened.

    This has proved to be a sticky problem. Fortunately, my computer still works well. It is just that I do not have corrupt files hidden.

  • ONS 15454 presents itself as 'unknown' after power failure

    We had a power failure that also landed an ONS 15454 in a remote installation. To restore power and power on the device, it appears in the CTC under gray with "Uknown2" as the name.

    I had someone reinsert the card of STC, but sometimes still unknown.

    Has anyone seen this? Suggestions (the unit is hours from me)

    Try to restart the session from the CTC and clear the cache of the CTC

    You can test the node

    Checks whether the node is in the OSPF routing table

    You can access through the CTC locally

    Your CTC terminal is directly connected, or does it go through a firewall

    Probably resolved now how did you solve it?

  • Windows 7 starts problems with black screen and the cursor because of power failure

    I'm on a Windows 7 64-bit Home Premium OS. Start-up problems arose after the power failure (accidentally unplugged the charger, the battery was not in place) during a video call in Skype. Accessories attached to the laptop at the time were a Logitech Webcam, a dongle Bluetooth, microphone and headphones.

    When starting my laptop Asus N81VP, he'll go as far as the 'Starting Windows' logo, then I meet a black screen with a mobile cursor. I don't then right click, CTRL + ALT + DELETE.

    I tried the things:

    Start Up Repair = "cannot automatically repair."

    System Restore = no available restore points

    Windows Memory Diagnostic = at 100%, no screen of detected problems, then black with mobile cursor

    Networking Mode Safe Mode/Safe = black screen with cursor mobile

    Activate video low resolution (640 x 480) = black screen with cursor mobile

    Good known Configuration = black screen with cursor mobile list

    Start Windows normally = black screen with cursor mobile

    Please help me. I've had this laptop for less than a year, and it would break my heart to have to re - format.

    You seem to have exhausted most of the options available in such cases, except two:
    D ' log in under a different account.
    -To restore your registry files manually. See below for more details.

    On your heart that could get broken: have you considered using the imaging facility that is integrated with Windows 7? You can find it in the control panel / backup and restore. This is somewhat marginal in the feature and it can be finicky, but it saved my butt several times.

    You can restore your registry files manually to a previous point through the steps described below. The process is complex and requires some careful typing. Ask a computer-savvy friend to help you if you lack experience in this field. Note that it may reset your password to a previous value.
    1. keep tapping F8 during the first phase of startup.
    2. Select repair in the menu that looks like this:
    http://Windows.Microsoft.com/en-us/Windows-Vista/advanced-startup-options-including-safe-mode
    3 log in as administrator if you are prompted.
    4. Select repair when prompted.
    5. Select the command line in the menu that looks like this:
    http://Windows.Microsoft.com/en-us/Windows7/what-are-the-system-recovery-options-in-Windows-7
    6. identify the correct drive letter for your Windows installation. It could be one drive other than c, but it will not X:. You do this by typing commands
    DIR C:\Win*
    Dir D:\Win*
    dir E:\Win*
    until you find the Windows folder.
    I'll call this "Q:" drive
    7 type these commands:
    CD /d Q:\windows\System32\config
    xcopy *. * Q:\MyRegBack\
    CD RegBack
    dir
    8. review the dates of the software, system, and SAM files. The files created before or after that is your problem?
    9. If they were made before the problem appeared, you can then type these commands:
    copy software / y...
    /y copy system...
    /y copy Sam...
    (the two points are part of each order)
    10. restart normally. If things don't work then you can go back by copying files from the original register of Q:\MyRegBack to Q:\Windows\System32\config.

  • Computers that are affected by a power failure

    Last night while I was watching TV, the power went out just for a few seconds, then she came back. I don't think anything of it, but, when I went to use my computer the next morning, he was sounding like a war was going on inside. The only thing I forgot to mention, is that I don't always close my computer before going to withdraw during the night, while he was at the time of the failure. Something does not look good and he echoes and I can tell by the power button it seemed that it was not a fixed light, it vibrated. I just hope that it is something that can be fixed. The thing is, I intentionally used these power strips that the electricity company gave to those who wanted to conserve energy, and also I thought it was protected power strips. Now, if someone can tell me if there is a chance that this computer can be repaired and not corrupt, and the ability to fix it myself, maybe? I am at a loss without my computer, and the possibility to buy another is out of the question because I am on disability and I have no savings. Please, if anyone can help me with this one, I'll be very grateful. If there is an organization that provides computers to people in need, it would also be a blessing, or a place or a person who fixes them for a fraction of what the prosecution remains. Thank you, Christina

    Before you start worrying too or attempt to make any kind of troubleshooting, you should consider that the most common result of a power failure while a computer is turned on is nothing.

    This is particularly the case when the computer has not been used for awhile before the power failure.  It sounds like your case: you were in front of the TV and not to use the computer.  Depending on the configuration of your computer to the top, it's probably in standby or, at most, just sitting and idling.

    As a general rule, when a computer is not actually in the Middle using the hard drive, the most that will happen after a power failure is when the computer is next turned on, you will see a message that 'Windows was not properly shut down' and we'll give you a few options.  The option to choose from at the point is to 'start Windows normally.'

    After writing all this, please answer the following questions:

    1. When you first went to your computer the next morning, he was turned on or off?
    2. If it was turned off, what happened when you the activated?
    3. If it was on, click the Start button and turn the computer off (Shut down).  Wait for 2 minutes and turn it back on.
      • What is going on?
      • Windows comes up normally?
      • The computer always made strange noises?
        • If so, are the sounds of speakers or mechanical noises from inside the computer?
    4. What is the brand and model of the computer?

    If the computer is mechanical noises (I'm not sure what you mean by "sounds like a war was going on inside"), your best course of action is to turn off and take it to a computer repair shop local independent (not a chain of stores).  Too little likely, a fan — or worse, your hard drive - could have been damaged.

    Oh, and these power strips - insofar as they work - prevent power surges ' "(surge), no power failures.

  • Error code 10 cannot install Maxtor 3200 after power failure

    Original title: maxtor 3200 code 10

    After a power failure cannot not re install Maxtor 3200 get response Code 10

    Hello

    The Code 10 error code is generated when the Device Manager has not enough information or error that spread upwards by device drivers is not recognized by Device Manager. In addition, this error may occur if one of the pilots who needs the unit does not start. If multiple drivers are used by a particular device, it can be difficult to determine which failed.

    I suggest you run the FIXIT from the link below and if it helps. You can also follow the manual steps and check.

  • Hello, I receive a message telling me that my AC power adapter type cannot be accepted.

    A few days ago, I started having a power warning message when I turn on my laptop. It is said that the AC power adapter type cannot be determined. Beacause it my battery will not charge. But it's the power adapter that came with it and I have used for so long that I got the machine. Do not know what is happening.

    I guess that the laptop works on AC power only but always?

    If you remove the battery from the laptop work?   If yes then I suspect the battery does not have rather than the power adapter.
    If it will not work without the battery then I would suspect that the adapter is faulty/defective.
    Don't let not the battery-even if it is the problem.
