  • 11 - k000na: problem of restart of the operating system after disk erasing

    Hi there are members of the HP support forum!

    I bought my product, the HP Pavillion 11-k000na, in October of last year and around in time to March this year, I found the speed of the computer to be really bad, so I decided that I do a disk cleanup and restore the computer to factory settings I've done. Restart the computer, I discovered that something has gone wrong and after many failed attempts I could not restart the operating system.

    Time and time again, the laptop gives me the same error - message

    Error code 0 xC0000001

    When I bought the computer it came installed with windows 8 and I've quickly updated to windows 10, would be the problem that when I restored it to factory settings, it does not know how to restart now?

    Any help would be really useful thanks!

  • How can I recover the modules and their data from a failed HARD drive (the lost BONE areas, but data files are readable)?

    The HARD drive that was my OS (Windows XP Pro SP3) failed and lost quite a few areas which are essential for the operating system running. Other data is still readable. A got another HARD drive and installed Windows XP SP2, Firefox and other programs. I was able to retrieve the bookmarks, security certificates, and other profile information using the information found in bandages.

    None of them addressed how do to recover the modules or their data. Specifically, there are several large, elegant scripts that took months to develop and customize.

    Articles related to migration and other do not work for me because they require the old copy of FF is functional, that is not because the OS on this HARD drive is damaged. Is it possible to recover these data, similar (or not) about how I could get the other profile info?

    Have you copied the entire folder C:\Documents and Settings\username \Application Data\Mozilla\Firefox\ on the old drive?
    If this is not the case, can you?
    If so, make a copy and save this folder just in case.

    If so, you could replace this folder on the new facility by \Profiles\ [with your profiles inside] folder and the profiles.ini file [delete all other files / folders that may also be in the folder "Firefox"] -and then replace with the same folder named from the old failed drive. Note that you will lose what you already have with the new installation / profile!
    Your profile folder contains all your personal data and customizations, including looking for plugins, themes, extensions and their data / customizations - but no plugins.
    But if the user logon name is different on the new facility that the former, any extension that uses an absolute path to the file in its prefs will be problems. Easily rectified, by changing the path to the file in the file prefs, js - keep the brake line formatting intact. The extensions created after the era of Firefox 2.0 or 3.0, due to changes in the 'rules' for creating extensions usually are not a problem, but some real old extensions that need only "minor" since that time can still use absolute paths - even though I have not seen myself since Firefox Firefox 3.6 or 4.0.

    View instead of 'Modules' I mentioned the 4 types of 'Modules' separately - Plugins are seen as 'Add-ons', but they are not installed in the profile [except those mislabelled as a "plugin", when they are installed via an XPI file], but rather in the operating system where Firefox 'find' through the registry.

    Note: Migration articles can tell you do not re - use the prefs.js file, due to an issue that I feel is easily fixed with a little inspection and editing. I think you can manage that my perception is that you have a small shovel in your tool box, if you encounter a problem you are able to do a little digging and fixing problems with the paths to files - once you have been warned.

    Overall, if you go Firefox 35 35 or even Firefox 34 to 35, I don't think you will run in all the problems that you can not handle [that I cross my fingers and "hope" that I'm not on what it is obvious].

    With regard to the recovery of the 'data' for individual extensions - there are many ways that extension developers used to store their data and pref. The original way should save in prefs.js or their own file RDF in the profile folder. While Firefox has been developed more, developers started using their own files in the profile folder. And because Mozilla has started using sqlite database files in Firefox 3.0, Mozilla extended their own use of sqlite, as have extension developers.
    Elegant uses the file stylish.sqlite to store 'styles', but something in the back of my mine tells me that 'the index' maybe not in this file with the data. But then again, I can be confusing myself a question I had with GreaseMonkey awhile back where I copied the gm_scripts folder in a new profile and with already installed GreaseMonkey but with no script. These GM scripts worked, but I could not see them or modify them - they do not appear in the user GM extension interface window in Firefox.

  • Vista does not start, fails to Startup Repair indicating that the version of the operating system is incompatible with Startup Repair tool

    I use a laptop Dell XPS M1330, under Vista Home Premium 32 Bit. The laptop froze, I tried to do a system restore, which did not work. Now the laptop goes into startup each time put on repair. A message window appears saying "Startup Repair cannot repair the computer automatically. Startup Repair window says "Startup Repair could not detect a problem. Diagnostics details say: Root cause found: the operating system version is incompatible with Startup Repair tool.

    I tried to use the Dell Factory Image Restore to restore the system, but it does not end. I get an error message instead. There is no details, it's just a small window with an X and the Word error.

    I also tried to use resettlement Dell DVD, but that doesn't seem to work either.

    Vista does not start at all, not in either safe mode.

    I just ran to the Dell Diagnostics tool, and that is to say that the integrity test of memory has failed... No idea how to solve this problem?

    I'm at a loss and helps woukld be appreciated.

    Hi James,

    Ø are you using the correct version of the Vista disc to run Startup Repair?

    I suggest to run the diagnostic tool memory WINRE mode and check if the memory (RAM) installed on the computer works fine.

    Follow the steps below to start the computer using the WINRE and run the memory diagnostic tool.

    A. Insert the Windows Vista installation disc.

    B. restart your computer.

    C. Si you are prompted, press any key to start Windows from the installation disc.

    Note: If your computer is not configured to start from a CD or a DVD, see the documentation provided with your computer. You may need to change your computer's BIOS settings. For more information, see BIOS: frequently asked questions.

    D. choose your language settings, and then click Next.

    E. click on repair your computer.

    F. Select the operating system you want to repair, and then click Next.

    G. in the menu system, SelectMemory diagnostic tool Recovery Options.

    Once scanning is complete, check to see if the problem is resolved.

    Access the link below to learn more about Windows recovery options in Windows Vista.

    http://Windows.Microsoft.com/en-us/Windows-Vista/how-do-I-know-if-my-computer-has-a-memory-problem

    If you have several sticks of RAM installed on the computer, you can try to remove one of the RAM stick and check if it works very well. Also, you try to exchange the RAM sticks and check if one of the RAM is originally this issue and if it needs to be replaced.

    Note: If you are not aware of the evolution and swaping the stick of RAM on the computer, it is best to contact the computer manufacturer for help on this and you can do it at your own risk.

    You can also contact Dell support and check if you need to replace any hardware.

    I hope this helps. Let us know the results.

    This sounds like the BIOS failed in a different startup command, or
    you have a USB key that tries to start and failed (for what is obvious
    reason!)
    -Make sure you have nothing plugged in USB ports except your
    Mouse keyboard &, if necessary.
    then try a cold start
    If it works, then plug your USB stuff one at a time, each reboot
    time - see that it causes.
     
    If it doesn't, then check the Boot in the BIOS order - to ensure that
    the CD and HD are the first two devices (up to you that who!) and who
    Activate you the option "other devices balance"if it's there. "
     
    See if that cures it.

  • Restart a session of planning tool instead of the operator

    Hi all
    We can restart a session failed in opertaor to restart from the component where it failed. Is it possible that we can restart a session in any Scheduler tool?

    It is possible to restart a session, the current session that failed if you wish. This can be done from the restartsession.bat/sh from the operating system command, or you can use the Web service, or by using the api call.

    For best performance, I would say not less 4 GB and preferably 8 GB or more.

  • If I kill Winlogon.exe in an attempt to restart or stop a device could cause corupted becaome the operating system

    I was told that if I had to kill the Winlogon.exe in an attempt to restart or stop a device could cause the operating system to become corupted.

    I'm uaing a feature of windows 2000.

    Hello

    1. How did you kill? via the Task Manager?
    2. do you use the Windows 2000 operating system?

    The process "winlogon.exe" runs in the background. Winlogon is a part of the Windows login subsystem and is necessary for the user authorization and activation of Windows controls.

    Murder winlogon.exe can make your computer unable to open a session, but I doubt it would have damaged the operating system. It is necessary that you let Microsoft Programs and services run without interruption for the proper functioning of your computer.

    Note: The winlogon.exe file is located in the folder C:\Windows\System32. In other cases, winlogon.exe is a virus, spyware, Trojan or worm.

    Original title: need for disk space

    Here are the official specifications of Toshiba for your PC...

    http://support.Toshiba.com/support/staticContentDetail?ContentId=638405&isFromTOCLink=false

    All interface PATA (IDE) connectors are a standard 40 pin.

    I know that there is no restriction on the mixture of ATA drives with different speed capabilities and no restrictions on what cable you use, whether 40 wire or 80 strand (but still 40 pins).

    Faster drives will only work at the speed of the slowest car on any cable and 80 strand cables are needed to make ATA66 or higher drives run at their native speed.

    In addition, no player can work faster than the motherboard chipset permits, in your case ATA66.

    My provider of trade has still some disks 3.5 '' PATA in stock, but these are becoming harder and harder to find. Indeed, it is possible that production has ceased and that suppliers are just exhausted stocks.

    I can certainly say that, when repairs this technology were more frequent, I never had problems with discs theoretically faster on the same cable as slower drives, nor by using faster on 40 cable strands discs. In fact, of many penny pinching manufacturers (some of them major) regularly used for the optical drive and hard drive on the same cable as the motherboard has two connectors, resulting in a decrease in performance on the disk hard (although most of the people would not have noticed the difference). Sometimes, the cable would be 40 strand (understandable if you are penny pinching) and sometimes the cable would be 80 strand (laughable if you are penny pinching because they are [were] more expensive).

    Pass your question about vacant below the sound card. Unless your text confused me, this space is for expansion cards no disk drives. Space that you reference is probably to the back of the PC. Hard drives are normally located toward the front of the dedicated PC "berries". Unfortunately, I could find no photo on the Toshiba site, and still less those internal.

    Hello

    1. have you made changes on the computer before this problem?
    2 - what you want to say that you receive this error message during the installation of Windows XP?

    Check to see if the following is useful.

    Method 1: Disconnect all devices non-essential connected to the computer and restart. Check to see if it boots normally.

    Method 2: You may need to check the settings of the BIOS (Basic Input\Output System). Check if the hard drive is detected. If this is not the case, check the physical connections. Refer to the manual to check the same.

    Warning of the BIOS:

    BIOS change / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.
