No sound on my laptop, using Windows 7

Hello

I have 1 1/2 year, computer laptop Toshiba - Satellite model No. C850-P5010, serial number 4C131836Q. Three of the last four days there no sound at all on the computer. I checked, is not on the button mute. Previously, the audio completely, stop sound creaked and after two three days it completely off.  I have frequent power outages in my residential area.

I also watch TV on my laptop using the dongle.

I have the Professional Windows 7 operating system on your laptop.

Please suggest the solution as soon as possible.

Thank you.

Have you read the second part of my first answer?

"I have frequent power outages in my residential area.

The blackouts, unfortunately, can damage equipment.

If the problem persists after you have reinstalled Audio drivers, I suggest you have the machine looked at by a Toshiba Service Agent if under warranty.

If it is under warranty, contact a local and reputable computer repairer and ask them to test

See you soon.

    Hi John,.

    I'm sorry to hear that you are facing this problem with one of your important files. I'll certainly try and help you recover the file.

    Plug the USB and run a scan complete using the scan Microsoft Security check for infections.

    Note: there is a risk of data loss if all the files are infected and which can be removed in the cleaning process.

    Sometimes, when pen drives be infected by some kind of virus, it can replicate this folder in the drive and hide the original file. You can follow the steps in the article to view hidden folders and check if it helps.

    Hope this information was helpful and let us know if you need more assistance. We will be happy to help you.

    Gmail doesn't have to be open in a tab. But Firefox must be run.

  • Laptop using Windows key to install Windows on another CD of license

    Hi all.

    I'm from Portugal, if my laptop came with a recovery dvd that installs Windows XP Home Edition in Portuguese language.
    My question is: is it possible to install Windows XP Home English from a different CD (no not via the dvd recovery) and continue to use the license key of windows that comes with the laptop?

    for example, is the license key for laptop for Windows XP Home Edition (any language) or specifically for Windows XP Home Portuguese?

    Thankx in advance!

    Hello

    NO, it is not possible to s. The key that is located on the cover of the CD is not activation key for Windows OS. This key you use to activate the Microsoft OneNote, which is preinstalled on the image of Toshiba.

    More info. :
    Usually, the image of Toshiba is already activated and you n t need to activate the image of Toshiba.

  • twinkling of intermittent screen on laptop: using windows vista

    Hello
    I use Windows Vista on my laptop about 2 years back (HP dv5 series)
    All of a sudden a week, the screen started to Flash intermittently... it almost goes running with all the white lines, for a second or two... and then stops himself. Sometimes it happens very frequently, like three times in an hour, and sometimes not even once in 3 hours.  Windows Update is on and all the drivers to date by themselves.
    I tried restoring the system to a date before I started having the problem on my laptop. It worked fine for a day, and then the problem started again.
    Can someone please suggest what to do? In addition, this flicker of the screen would lead any type of damage to the screen if not checked soon? My laptop is out of warranty and I'm not sure what to do.
    Thank you

    Hello

    drivers are normally specific model

    and HP provides the drivers for their products

    so, you need to ask HP if you can swap the drivers around model to model

    and Yes to keep an eye on what the drivers left 3rd update windows wants to install on you!

  • How to install my BT stack for windows on the laptop using Windows Vistta SP1

    When I try to install my newly bought USB Bluetooth adapter (CN-512/521 v2 001) on my laptop from another production that has an operating system of Windows Vista SP1, it will help not make me, saying "Bluetooth Stack for Windows incompatible with this version of Windows, please check with Toshiba - contact Toshiba on upgrades or other possible solutions to make this program compatible with this version of Windows.

    But when I was directed to the Toshiba site I could not find any help or advice on this subject. Can someone tell me what to do?

    You are right. Use at least 5 or later if you want to install a Vista. Visit the website of the seller adapter USB Bluetooth if a newer version is available. The version on the Web of Toshiba Bluetooth site is customized for these books, and not as a result of your hardware.

  • No sound on Portege R500 using Windows 7 RTM

    Hi all

    I have the problem of sound with Windows 7 RTM. No sound playback, the microphone works very well and the control panel > hardware and sound > Realtek HD Audio Manager detects whenever a microphone or headset is (UN) plugged.

    Any driver I install and no matter as the playback source (sound system, Media Player, Winamp and others), there is no playback of the sound on the speakers or the headphones. The last I installed Realtek R2.31 is.

    I start to wonder if what happens to be fixed, after all, Windows 7 is to go gold and there is no solution for this problem.

    Hello Paulo

    If you see this section of Win7 you will find a lot of comments but a general message is: Win7 is not published official and drivers Toshiba doesn't offer WIN7 at the moment. When the Win7's official published Toshiba will start Win7 support, and I hope that your Portege will also build.

    This means that Toshiba will offer drivers Win7 on Toshiba download page. These drivers will be tested and it should work properly. Now on US Toshiba support page you can download some drivers Win7 BETA (untested). If you want to check under http://www.csd.toshiba.com/cgi-bin/tais/su/su_sc_modSel.jsp

  • How can I install Age of Empires 3 (for XP) on my laptop using Windows 7?

    I was SO excited to finally get a laptop (Asus K series) game with a quality graphics card, a serious upgrade from my old Dell Inspiron. I was disappointed, however, after discovering the lack of compatibility and therefore the obstacle to play, with Age of Empires 3 fantastic games.  I would really like to play the game as it was meant to be played, but I have no idea how to install it.

    Is there a compatibility program I can run, or a shortcut through it all?

    Thank you!

    ~ archaeknight

    I found this on the forums of AoE, it seems reasonable:

    When you install the game on Windows 7 won't allow the CD autoplay but rather explore and click on setup.exe, and select 'run as administrator '. After that the game installs explore the directory of Age of Empires and find the application, create a shortcut for it and in the properties of the shortcut, check both boxes "Run as Administrator" and set the compatibility "Windows XP, Service Pack 3.

  • to use my android with my laptop using Windows phone 7 to access the internet via my mobile network without wifi

    I tried to use pdanet as well as samsung software to activate droid to attach it to my computer and allow my computer to use my mobile network (no wifi).  can't seem to make this work.  my computer shows the phone droid as a recognized device.

    Sorry was a little confused, you ask a question on a Microsoft Forum Android.

    On android, you try to perform a "tie".  Depending on your operator, which may require add them a feature to your account to make it work.  There are several applications out there, that you can use to root your phone to install applications that will try to fake on the carrier.  Here's a piece of Security Council 'Root never your phone', it will cause problems and make you more vulnerable to exploitation thereafter.

    But back to tie, I guess that you do not want to pay for an app for a quick search of the Amazon AppStore poster a few promising ones:
