How to use the original sound system in my laptop?

My Toshiba Satellite laptop came loaded with Realtek sound card and speakers. I added something to my computer that has added another audio system. When I looked in 'Device Manager' then sound all I saw was "High definition Audio Device" and did not have a Realtec. HDAC should Realtec as audio device have been replaced. The Realtek High Definition Audio Driver and Realtek USB 2.0 card reader are always listed in "programs and features. How can I make my sound legacy Realtec main?

Is it the same in the two sections below?  Honestly if your sound does not work, I wouldn't touch it. But otherwise, head to the Toshiba site and re-download the original pilot.

  • Using the preloaded operating system of a laptop.

    Can I use a preloaded OS (Windows Vista) to my old laptop (not working-HP Pavilion DV5) to a new laptop. But my other laptop Lenovo thinkpad. Although I m an owner legitimate of the (old) laptop so I should have the right to use on a laptop by closing the old laptop.

    Hello

    No.; You can't use it on another PC.

    Preinstalled OEM licenses are much cheaper to buy than the retail licenses and this is one of the reasons why they may not be transferred

    If the computer/laptop comes with the preinstalled Windows operating system (Dell, HP, Acer, etc.) or is licensed to OEM System Builders, that the product key that came with the computer/laptop is preinstalled OEM license and is not transferable.

    OEM license/product key (systems of operating pre-installed on Dell, HP, etc.) and the license OEM System Builders are related to the first machine it is installed on and dies when machine who dies.

    Only retail Operating System license that you buy and install yourself, are allowed to be transferred to another machine.

    And retail licenses also can be installed on a machine at one time.

  • How update without the original operating system?

    I recently had to buy a hard drive for my counter top. I did this do not know that the operating system was not on it. I returned to Best Buys and the geek squad guy told me that with the new drive hard I have to install the operating system. Because I didn't it was suggested to upgrade to Windows 7 Professional. Did not say anything else, so I bought a program two cents of dollar only to find out that this program is for an upgrade and not a new drive. Now I can't turn it on at all. Can someone please? Can I take that back and negotiate it? I'm not sure.

  • How can I start my XP desktop PC using the original CD of the Windows XP operating system, but I don't remember my password?

    The last time I asked a question like that, someone made it is perfectly clear that they would not help me to crack a password..., three times. If you have any suggestions that may help me in fact, I'd be in your debt. Otherwise, save your time and ignore all this.

    I am trying to perform a repair to the XP operating system. When I try to boot from the CD drive using the original Windows XP disc, I can not connect. It's a dead-end.

    When I try to boot from the hard drive, the system reaches a certain point, and then it re-boots. If I just sit and watch, it keeps re-initialization. Strange thing is that recently, I changed the password. I simply do not remember what it is. And, seriously, I have experienced repeated amnesia episodes. The obvious thing to do is to keep my own hand written records..., I only using computers since 1982, before IBM introduced its first PC.

    The BIOS provides a way to clean up all the stored passwords? This is where I'm going next.

    I apologize for being a little rough. Part of that comes with age.

    Jeff

    Hello, Jeffrey. I just read one of your other threads. Brian Tillman brings a great point that you missed. The BIOS password (if it still exists) has absolutely NOTHING to do with the other passwords, including those for things like a Windows XP profile.

    Unless you have created passwords, while they do not exist. So, if you need to boot from the Windows CD using the Recovery Console, and you are prompted for a password, then chances are that just by pressing the Enter key (indicating an 'empty' or empty password) is all you need to do.

    So, if I were you, I would not at all concerned about your BIOS.

    In addition, I think you mentioned that you couldn't even see the administrator account. Assuming you have Windows XP Home Edition, this is how it is supposed to be. If you want to see it, you will need boot mode safe. Then you will see. :-)

    If you DID create a password and have no idea of what it is, there are tools to reset your password. But I think that people don't post links to these programs in these forums Microsoft (not very well why). But they are easy to find if you use a search engine.

    You say that you have recently changed a password, but you did not indicate what it was for. It is important to understand that the built-in Administrator account is NOT the same as another account that you are using happens to have administrator privileges. And assuming that you never set a password for the built-in Administrator account, so if you are using the Recovery Console, everything you need to do is press the Enter key.

    HTH.

    o The System Restore tool

    If the problem you are experiencing started occurring recently, you can use the System Restore tool. Using this tool, you can restore the computer to an earlier point in time. The tool using System Restore may not necessarily help you determine the problem. When you use system restore to restore the computer to a previous state, the programs and updates that you have installed are removed.

    To restore the operating system to an earlier point in time, follow these steps:

    1. Click Start, type system restore in the search box, and then click System Restore in the list programs. If you are prompted for an administrator password or a confirmation, type your password or click on continue.

    2. in the System Restore dialog box, click on choose another restore point and then click Next.

    3. in the list of restore points, click a restore point created before you started having the problem, and then click Next.

    4. click on finish.

    The computer restarts and system files and settings are back to the State they were in when the restore point was created.

  • Pavilion dm4-3090se: how to use the SSD after restoration of the system of Windows backup disks?

    Hello

    After a lot of work, I finally could restore my OS using Windows backup disks that I created a few years back. (The OS has been corrupted when the power has been accidentally deleted from the system and the battery was dead)

    Restoring backup widows put everything on 444 GB C drive.  Nothing I put on the SSD drive d:-20 GB and there is nothing in the tools of HP E: drive - 4 GB

    How can I make use of the SSD drive to help speed up the system?  I see the system starts and runs more slowly now.  I'm ready to blow the current operating system and re-run the Windows backup utility.  But I need to know how to use the SSD during the restoration.

    Any help is appreciated.

    Thank you

    Bob

    Hey @llebrez,

    Welcome to the Forums of HP Support! This is a great place to find solutions and help our community!

    I understand that you have some information about using the SSD in your HP Pavilion dm4 Beats Edition Entertainment Notebook. I'd be happy to help you with that.

    The SSD in your laptop is used for a technology called Intel Smart Response. Intel Smart Response uses the SSD as a type of Cache smart to help load the items faster. The reason why that is not used currently is because the restoration of the system is not designed to use the SSD for intelligent caching and is not able to establish that on its own.

    If you want to configure Intelligent caching on your laptop, you can follow this guide provided by overclock.net: how: implement the Intel Smart Response Technology (SSD caching)

    I hope this helps. If you have more questions that I'm able to answer for you, please do not hesitate to ask.

    Please hold me.

    Hi deacon829,

    You did changes to the computer before that happened?

    Step 1: Start the computer in safe mode and check if the problem persists, to do this, follow the steps below,

    Access the menu advanced startup options by turning on your computer and pressing the F8 key before Windows starts. In the advanced startup options select safe mode

    http://Windows.Microsoft.com/en-us/Windows-Vista/advanced-startup-options-including-safe-mode

    Step 2: If you try to install any application before this program, try to uninstall them.

    http://Windows.Microsoft.com/en-us/Windows-Vista/uninstall-or-change-a-program

    If this solves the problem, you can deduct that the demand is probably corrupted, damaged or incompatible. You can check with the manufacturer of the program for more information.

    Step 3: System Restore: System Restore to put the computer's system files to an earlier point in time.

    Look for steps to restore of the system in the link below:
