  • Left speaker not working 100%

    Hello

    The left on my MacBook Pro for mid-2014 speaker does not work as well as my only right. Sometimes during music or gameplay, it would "pop" and return to normal, but recently it stopped doing this. He still has his fate of it, but it is quiet and distorted. My right speaker works perfectly.

    Any thoughts on how to fix it?

    Thank you!

    I am not that at all, but then again I have had mine for about 2 weeks to more now.

  • Speaker not working after installation of Service Pack 1 of Vista.

    I have been under Vista Home Premium on my laptop for about 2 years, but have only now went on the internet with it.  I did the updates of windows, including Service Pack 1.  Now the speaker on the laptop does not work.  If I put the mouse on the speaker icon in the lower right corner of the office, he said that no audio output device is installed.

    Before I installed the SP1 download, I have my favorites of a link to the Microsoft page saying that this problem can occur.

    http://support.Microsoft.com/kb/936330

    This led to an application download of Mr. Fixit I read to mean he could diagnose and fix the problem.  All she could say is that there is no audio output device installed.

    So, is it a driver problem caused by Mr. Vista SP1 from Microsoft?  Or what it is - this?  (I was quite civilized with the language that I used here - I would like to meet face to face!)

    Seriously, I hope someone can help me here please.  I'm not one of the younger people really in place with computers, but I'm not totally computer illiterate either.

    Thanks in advance,

    Hi, I'm back!

    Problem seems to be solved - speaker is back!

    I just made a couple more windows updates that require a reboot.  To my surprise and my greatest pleasure, I heard the sound of Windows in the process.  It may not have been restarted because I updated Vista with Service Pack 1 yesterday and there is no sound when I started the laptop today.  Perhaps the latest updates is done.

    See you soon,.

  • Click right does not work. Profile already deleted and started in safe mode

    I googled and used solutions of mozilla for safe mode, delete and create a new profile (deleted all files) disabled all the plugins. I discovered a problem where clicking on ask to activate does not drop down to select another option. I tried the plugins folder thought I could delete all the plugins and start again. Nothing I've tried has worked at all. I also uninstalled and reinstalled the latest version. I noticed that the version installed is under program (x 86), which is where I thought that 32-bit applications are implemented? Anyway, even by selecting text on a page and right click does not work

    You have a problem of mouse anywhere else?

    The software on your system is up to date?

    Start your computer in safe mode with network. Then launch Firefox.
    Is always the question?

  • M40X-129: the two usb ports on the right does not work

    Hello people.

    Two days ago, I bought a satellite m40x-129. I wanted to use a usb mouse and a drive hard usb so I had to plug the device into a a usbport on the right side of the laptop, but is does not work.
    even after reinstalling with windows xp pro (I need to connect to a primary domain controller) has not changed. I installed all the drivers of the tool-cd burned by a toshiba tool in the original installation.
    Maybe it's a hardware fault. someone else has the same problem?

    Thanks, jens

    today I updated my drivers for the new 7 series chipset from intel, but the usb ports on the right still have no power and do not recognize any device.
    I'll ge see my local dealer Monday ;)

  • Paved touchscreen and button right does not work on Satellite L300 with Vista

    My right button does not work.
    By clicking on the icon on the desktop, the drop down menu does not open and when you work in some programs (Indesign).
    In addition, sometimes the touchpad does not work.

    Reset is useful for a little bit.
    I have install the driver of Synatpics 11.2.4.0.
    Is there something else I can do besides sending it to be repaired.

    I just got this laptop 3 weeks ago and I hate Vista.

    Hello

    I put t think this could be a hardware problem.
    First of all, you should try to update the driver for the touchpad.

    First remove the touchpad driver in the system.
    Then, visit the page of European driver of Toshiba and download the latest touchpad driver and install it.

    PS: If you use an external mouse and that you have installed the mouse drivers/tools then this could also affect the functionality of the touchpad.

  • 14:Two yoga made 3 finger tap a click right does not work, no way to disable the Tracker for palm

    I have recently buy Lenovo Yoga 3 14 inches and have found that I cannot disable followed two palm or use two fingers click right tap function.

    I went in the mouse settings but still no help, it is said that tap two fingers is enabled but does not work, all other touchpad gestures work perfectly. I currently have the driver version: ELAN Touchpad 11.4.54.1_x64

    If it's any help, the virtual mouse device of Lenovo also has the version of the driver 14.20.52.752

    I already checked the MOMENTUM without result and also parameters of lenovo found in Program Files/Elantech. They both contain palm Tracker settings, but they are put at least still do not clear up my problem.

    If I can't fix the two finger tap or palm Tracker option that I plan to take my back just Lenovo for the hassle it caused.

    I did my research but still no results found. Help, please!

    That help me:

    I have the solution:

    Run regedit

    HKEY_curreent_user/elantech smartpad /software/.
    Tap_two_fingers value 1
    Tap_two_fingers_enable value 1

    Reboot and then you can use 2 fingers to the right click

  • click right does not work, Ctrl + C is. Vista Home Premium 64-bit

    Tried restoring the system with no result.  CMD: SCF/scannow showed corrupted files, but could not fix.   I do a recovery?

    Hello

    Because these two problems are related to the various pieces of hardware, they cannot be related. In addition, they cannot be related to sfc/scannow results. If there is a hardware problem, re - install the operating system would not solve the problem. The first thing we do, if possible, is cross test equipment. Of course, if it is a laptop the first step can be taken...

    1. The keyboard (ctrl-c) works on another PC? (Right-click) mouse works on another PC?
    2. Another keyboard (ctrl-c) works on your PC? Another mouse (right click) works on your PC?

    Or the other of these problems only occur in some programs, or they occur in all programs?
