My dv7 has a very bad warble in the audio after a recent automitic upgrade.

My dv7 has a very bad warble in the audio after a recent automatic upgrade.  I have tried to revert the audio drivers back to a previous version but that has not helped.

Hi Mikehow,
May I please you to write which dv7 you exactly own (e.g. a dv7-6190)? You could also post your P/N (not the S/N, please) here.
This would really help!
Thanks!

  • Nokia c3-01 has a very bad signal

    Hi,
    My name is mohammed
    i have bought a new nokia c3-01
    but i found that it has a very bad 3g or GSM signal
    and its signal always goes down
    even the sim is new

    Are you sure it's not a problem with your operator ?
    Did you try your simcard in another phone at the same location where you had bad signal with your C3-01 ?

  • Macbook has become very slow, i get the rainbow wheel whenever i click on something, i can barely do anything!

    My macbook pro has slowly been getting worse over the last few months, it takes ages to load up when i turn it on, and whenever i try to click on something (google chrome, itunes, etc) i get the rainbow wheel for an unknown amount of time, its so slow! i can barely do anything on it, im having to upload this question on my ipod because i cant use my mac, ive had the mac for about 4 years, and i dont think its anything to do with the memory, any help would be very grateful!

    Sounds like it might be your hard drive.
    Go to Applications -> Disk Utility, select your hard drive, and click on the "Info" button and see what is reported for your S.M.A.R.T status at the bottom of the screen:

  • I have a first gen ipad mini (no warranty) that has a very badly cracked screen.  I am seeing that it would cost quite a bit to replace thru Apple.  Has anyone used a 3rd party vendor??

    There are third-party services, and you should use Google to find them, and reviews of their services.

  • Very bad signal on iPhone 4 after upgrade to IOS 6

    After upgrading my iPhone 4 from IOS 5.1.1 to IOS 6, I started having lot of troubles with signal and signal strength: the phone is continuously switching form 3G to GPRS/Edge, signal strength is always bad, Internet access is almost unusable, and sometimes I can't even make phone calls or send text messages; even when it seems to have good 3G signal, as soon as I try to use it to do anything (even a phone call), 7 times out of 10 the signal drops.
    This doesn't seem to depend on the places where I go, and anyway I know for sure I'm now having signal troubles in the exact same places where I had perfectly good signal before the IOS upgrade. I'm in Italy, my carrier is TIM, but again, it worked perfectly fine before the IOS upgrade.
    Steps I tried to fix the issue:
    Settings -> General -> Cellular -> Cellular Data Network -> Reset Settings
    Settings -> General -> Reset -> Reset network settings
    Using iTunes: backup, reset (also downloading a fresh copy of the IOS image), restore from backup
    Nothing seems to have worked.
    I've been searching around, and it looks like many people have had similar problems after the IOS upgrade, although some of them seem also to have resolved it using some or all of the above steps; anyway, they were not enough for my phone.
    Is there something else I can try? Is this a known IOS bug? Is Apple working on some fix?

    Looks like the reset actually solved the issue. I posted the question soon after having done it, and the signal was still bad, but that was probably due to the place I was in. I've tested it for a whole day, and now signal strength is indeed like it was before upgrading to IOS 6.
    I also called Apple support, and they confirmed is a known bug, and a full phone reset solves it.

  • Very bad luck with the second I phone 5 in this month :(

    hello .....  i'm living in dubai ... ia have bought I phone 5 from etisalat but it was not contail facetime application ... so i bought a nwe one from the market but with international warrenty ... now i can hear sound like a screw not tight ... od one nut is loose .... please advice

    Take it for service under your "international warranty"; whatever that is. If you got it from a non-authorized source (the "market") in Dubai then I wish you good luck getting service.

  • Has there been a resolution to the wake up issue created by upgrading to OSX Lion?

    Since upgrading to OSX Lion my iMac will not wakeup. Has there been any resolution to this problem?

    This is a problem with your computer and system, not with Lion. I suggest you do the following:
    Install or Reinstall Lion from Scratch
    If possible backup your files to an external drive or second internal drive.
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Erase the hard drive:
    Select Disk Utility from the main menu and click on the Continue button.
    After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Erase tab in the DU main window.
    Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
    Quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion and click on the Install button.
    Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.
    Because the Lion volume will be erased I recommend you first backup your files so they can be restored after reinstalling Lion.

  • Very bad skype connection.

    Very bad. Recently, skype has been very bad between me and my girlfriend. We just can't here each other. It says the internet is bad but we both have strong internet and it has never done this before.

    Enable UpNP on both ends. Also use the call > show technical info, to troubleshoot the connection (packet loss, roundtrip etc).
    If on WLAN, use cabled connection to verify any issues.

  • AIR application performance is very bad(slow)

    I have an AIR application developed using Flash CS3. The
    issue is application performance is very bad(slow) when the OS
    (Windows XP) display property setting is in 16 bit color mode. When
    the display property setting is changed to 32 bit color mode
    applications performance is good and faster.
    Application has used lots of color gradients, tween
    animations.
    System Configuration:
    Windows XP (SP2)
    1 GB RAM
    INTEL P4 , 1.5 GHz Processor Speed.
    Can any one explain that is there any issue with Flash Player
    or AIR runtime.

    Do you have a link for any more info on this? Sounds

  • X3 02 very bad

    Hi this is unbelievable how Nokia can do this..?
    My sister recently purchased a X3-02 thinking it was nice & functional..WOW was she wrong.
    To her & my dismay we find there is NO security code lock feature (the one that can be activated to come on so no one can go through phone content or make unauthorised calls)
    The only security phone lock on this peice of junk is enabled when someone inserts a different SIM card inside or something.
    This phone has so many bad design faults, the touchscreen is so unresponsive, have to hit it twice before it takes action.
    There is NO front camera, she thought there was a front camera because theres a small black square on the top right hand side of the screen.
    This phone is not up to expectations & for nearly £100 I wouldnt call this a low cost handset.
    Previously a 6120c had better functionality than this peice of junk.
    Why are nokia not up to scratch on products these days??
    Will / can Nokia add the security code phone lock feature in next firmware update? I doubt that will happen, so it looks like this handset is going in the bin, because we would feel guilty selling this junk to a person.

    In the user guide of the X3-02 is says that you can set a lock code on the device which wil activate when you're not using the device.
    From the user guide:Lock your device
    Want to protect your device against unauthorized use? Define a security code, and set
    your device to lock itself automatically when you're not using it.
    Set a customized security code
    1 Select Menu > Settings and Security > Access codes > Change sec. code.
    2 Enter the preset security code, 12345.
    3 Enter a new code. A minimum of 5 numbers is required. Only numbers can be used.
    Keep the security code secret and in a safe place separate from your device. If you
    forget the security code and your device is locked, your device will require service.
    Additional charges may apply, and all the personal data in your device may be
    deleted. For more information, contact a Nokia Care point or your device dealer.
    Activate the security keyguard
    Select Menu > Settings and Phone > Secur. keyguard > On.
    The device is locked when the keys and screen are locked. You need the security code
    to unlock the device.
    However, if what's above is wrong you might have the rights to get the money back or get another phone as it is not fit for use.. Check it out first.
    But you cannot blame Nokia for not having a front facing camera on it just because your sister thought a black spot on the top corner was a cam. Even though it is a pitty, it's quite unfair to blame Nokia for that.

  • A small but very irritating bug in Mail: after pressing the spacebar after typing an apostrophe in a word such as "we're", the cursor moves to the left i.e. backwards, and not to the right, effectively deleting a space and not creating one.

    When composing an email in Mac Mail I've noticed a small but very irritating bug: pressing the spacebar after typing an apostrophe in a word, e.g. "we're", the cursor moves to the left i.e. backwards, and not to the right, effectively deleting a space and not creating one.
    Any ideas?

    I just recreated this problem on my iMac (wired KB, no wireless KB) by changing Mail > Preferences > Composing > Spellcheck from "as I type" to "never". Then type a contraction ending in 're and the space bar causes the cursor to jump back as others have stated, to the spot 'r|e
    Next, I went into System Preferences > Keyboard > Text, and turned off "use smart quotes" and the problem went away again.
    From this point (smart quotes off, spell checking never), if I turn Smart Quotes ON, the problem returns.
    The problem is dependent on the state of both settings.
    The spacebar in Mail "works" if I have either of the following setting combinations:
    Keyboard: smart quotes OFF, Mail: check spelling ANY SETTING
    Keyboard: smart quotes ON, Mail: check spelling AS I TYPE
    Other combinations FAIL
    Keyboard: smart quotes ON, Mail: Check spelling NEVER
    Keyboard: smart quotes ON, Mail: Check Spelling WHEN I CLICK SEND
    Looks to me like there's a bug in Mail > Preferences > Check spelling > NEVER and WHEN I CLICK SEND that interacts badly with Keyboard > Smart quotes ON.
    Thanks.

  • I am a macbook pro user form last 2 yrs, recently i upgraded to Mountain Lion from Snow leopard. Since then  operational  speed is a major concern. Now It has crashed so very badly that I am scared of my data.Please help me.

    I am a macbook pro user form last 2 yrs, recently i upgraded to Mountain Lion from Snow leopard. Since then  operational  speed is a major concern. Now It has crashed so very badly that I am scared of my data.Please help me.

    Reinstalling Lion/Mountain Lion Without Erasing the Drive
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
