Volume turning off by it self

what do i do if my touch smart 320 keep turning the volume down and don't let me turn it on , first happened when I while listening to power point presentation from a disconkey.

Might be related to HP keyboard driver (I think its call hpsysdrv). If this has been disabled, volumewill go to zero under certain conditions. You can reinstall the driver from HP Application and driver recovery. Start - all programs - PC help and tools - HP recovery manager - advanced options - reinstall drivers.

Please post rather than send me a Message. It's good for the community and I might not be able to get back quickly. - Thank you.

    Contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine.

  • HT201413 my iphone5 turn off by it self

    my iphone5 turn off by its self and when i connect it to the pc i try to restore it and its having trouble

    Are you sure that the battery didn't drain completely? If you know that the iPad battery should have nought juice left in it, try rebooting the iPad.
    Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
    But if you have any doubts about the battery, charge the iPad for about 30 minutes before you try the reboot.

  • Laptop turns off everytime 40-50 minutes by its self.

    So my laptop keeps turning off by its self. I have tried to remove dust and clean filters but it still does it. Any help?

    Hmm.. I would probably start with a hard reset (hold down the home button + sleep/wake button until you see a silver apple logo, then release). This reboots the software and can often help with these types of issues. If you try the hard reset and the problem persists, the next step to try is to back the phone up to iCloud or iTunes, reset to factory settings, and restore from back up. Hope this helps!

  • Sound alerts won't turn off

    How do I stop my MacBook Pro making sounds alerts like whizz, pop and buzz every time do something in an app.? I unchecked all the sound effect boxes in System preferences but that did nothing. They aren't sounds that appear on that list either. I have to keep the volume turned off instead.
    I did migrate files and applications from my G4 powerbook running 10.3 Panther to the new MacBook Pro, would this have had any effect?
    Any ideas?
    Macbook Pro 2.16, G5 iMac   Mac OS X (10.4.8)   Logic Pro, Final Cut Studio

    apple store pointed out the alert volume slider is not the same as the play user sound effects check box and you need to turn it down as well as unchecking the box.

  • Smart Connect can't turn off Bluetooth

    Hello,
    I purchased an Xperia Z3 Compact and Smart Connect is unable to turn off Bluetooth at the end of an action.  Below is the setup I have been trying to get work.
    - Bluetooth turned on manually
    - Turn on Bluetooth headphones.
    Smart Connect:
     - Start Action:
         - Connect Bluetooth headphones
         - Start Walkman App
         - Play track
         - Adjust Volumes
    - End Action:
         -Disconnect Bluetooth headphones
         - Pause track
         - Turn off Bluetooth
    The problem is that the Bluetooth will not turn off and I must do it manually.  The Bluetooth on and off works for wired headphones, but not for Bluetooth headphones.  Can this be addressed or at least send me information to get this fixed?
    Thanks

    I have this exact problem with my new Z2.
    - End Action:
         - Adjust Volumes: set wrong volumes
         - Turn off Bluetooth: does not work
    Sony, fix it with an update, please!

  • Volume stuck off; Refuses to respond to input

    Volume turned off on my computer -- and then it stayed off. I hit the mute button, but later, when I tried to turn the volume up, I saw the floating icon come up, the bar was all the way to maximum, but a "no" symbol was beneath the volume bar. When I tried to manually change volume in system preferences, the control bar and mute button were both greyed out. I plugged in my headphones, and volume works fine for them.
    Any ideas?

    When the light is on, the port thinks headphone/optical connection is active. It's a mechanical issue. I would recommend you NOT stick a toothpick in there: if a sliver gets lodged in there, Apple could reasonably refuse warranty service because it would appear to have been abused.

  • Last night I went to sleep, and when I woke up, my iPhone was just turned off and it doesn't want to get any power.

    My iPhone doesn't want to get any power; it was perfectly normal, and last night it just turned off by it self with 43% of battery.

    Plug iPhone in with Wall Charger for 10 minutes, iPhone may turn ON itself. If not on, then keep on Wall Charger and Reset, hold both Home and Power buttons until the iPhone begins to restart, may take around 20 seconds of holding both buttons.
