PC Pavilion laptop: no sound on Pavilion g6 after installing the new battery CMOS

I have a Pavilion g6z - 1 d 00 CTO Notebook PC, model A2F43AV number.  It came with Windows 7 Home Premium, and I upgraded the operating system to Windows 7 Pro (64 bit).

The problem is that I did not sound, either through headphones or the speakers even if the Volume is set at 55. I first noticed the audio problem after replacing the CMOS battery, as the laptop is 4 years old and he gave me intermittent wireless connectivity problems.  After installing the new battery CMOS, I noticed the wireless driver was missing and downloaded/installed.  Everything was fine except the audio.  Then I reset the BIOS but nothing there as the BIOS version is v.49, and it is the most recent.

I have also downloaded/installed the driver audio and rebooted the PC.  Still, there is no noise.

Finally, I have checked the audio drivers and the reporting system they work without any problem.

What should I do next?

Thanks, Terry


Thanks for the reply,

I was under the impression that these links would take you to guide step by step, however, it seems that they do not work,

However, I have provided details below:

To perform a hard reset on a computer equipped with a removable battery, follow these steps:

  1. Turn off the computer.

  2. Remove the computer from the docking station or port replicator.

  3. Disconnect all external devices from devices such as USB, external displays storage devices and printers.

  4. Disconnect the power adapter from the computer.

  5. Remove the battery from the compartment to batteries.

  6. Press and hold button power for about 15 seconds, remove any residual electric charge capacitors that protect memory.

  7. Insert the battery and plug the power adapter into the laptop, but do not connect peripheral devices.

  8. Press the power button to turn on the computer.

  9. If a boot menu appears, use the arrow keys to select start Windows normally and then press the Enter key.

  10. After you have reconnected each peripheral device, run Windows Update and HP Support Assistant to update all device drivers.

  • HP Pavilion DV6-6c35dx: potential problems with OS driver install the new hard drive?

    I want to spend the hard drive of my laptop, but my laptop did not come with recovery discs. I buy a full copy of Windows 7 Professional, but I did save it... because when everything has failed, I guess. If I'm able to reinstall Win 7 Home or if I have to install Win 7 Pro, how can I be sure to reinstall all drivers HP (p. ex., trackpad, meaning cool, beats audio, etc.) for my machine? It is best to download the drivers before you install the new hard drive and have them ready on a flash drive. or is there an easier way? Thank you.

    I personally prefer the new OEM installation & then get required drivers to download for HP support for your laptop model.

    It is slower and more difficult to do if it is not too well known, but the end result is much better.

    If your system has flaws you should try to fix first, but better long-term results come from clean install generally.

  • Laptop won't turn on after the new battery.

    A few days ago, when I got home, I found that my VAIO VPCF1290x of 3 years was dead. The battery indicator has been telling me to get a new battery, but I thought it would be enough for now.

    Problem: Laptop wouldn't turn on after pressing the power button.

    (1) with the adapter and the battery still in my laptop, by pressing the power button does not turn on my laptop. However when I press the power button, green light battery (the button itself) indicator on for about a second, then dimmed quickly.

    (2) after reading some forums, I decided to fill my laptop into the battery button for a good 30 seconds trying to turn slot WITH the adapter. It turned on my laptop, but it took a good 2-3 seconds for the laptop to make all sounds as if it was about to start.

    I have since then bought a new battery and a reason that my laptop lights at all. When I connected my new battery to condition it green button energy came on again for about one second then disappeared.

    I don't know what's the matter with my computer and would like to help. I KNOW that I should probably get repaired but would like an idea as to why my laptop behaves like a *.

    EDIT *.

    To give more information, when I have the OLD battery placed in the computer of the battery indicator is a constant flashing orange.

    With the NEW battery sony return the same thing occurs when the battery light constantly blinks orange.

  • GarageBand wasn't able to install the new sounds

    I'm under GarageBand 10.1.2 & OS X El Capitan 10.11.6 on a Macbook Pro 13 retina "(2016).

    A couple of weeks, that I have installed additional drummers with no problems. I noticed, however, that many of the sounds in the sound library had an icon to download next to them; so I went to the GarageBand menu, option "Sound Library / download all the available sounds" and they begin to download immediately. Most of them have installed fine (and is still usable), but at some point the download has stopped and a window appeared with the message "GarageBand wasn't able to install the new sounds. Close and re-open GarageBand to download and install again. »

    Since then, whenever I open GarageBand, downloading continues automatically, but after a few minutes I get the same annoying message.

    I searched the Internet and tried all the following without success:

    (1) closed and reopened GarageBand

    (2) given in market system

    (3) delete the folder "/ private/var/folders/lq/nb_0wt4d1zq5rs933745flww0000gn ' and all its contents

    (4) remove the "user/Library/Caches" folder and all its contents

    (5) the latest version of Java from Oracle (update version 8 101 - build 1.8.0_101 - b13)

    I always feel the same frustrating lock when I open GarageBand (download starts and after a while it stops and the error message shows up again... and again once).

    I've included some screenshots on this post below, which illustrate the issue.

    Thanks in advance for any help you can provide me with!

    Just to be sure - you have enough free storage to install all the new sounds? The instrument only GarageBand library has 14GB on my Mac.

    Until you try to install the sounds still launch the Console application and look for messages of diagnosis in the Console, when GarageBand gives the error message.  Are there clues, all messages associated with GarageBand in the Console window?

    Sometimes third part applications or incompatible system additions could cause this kind of problem, as firewall and antivirus software, for example, Little Snitch or Kaperski. If you have any of these installed, disable it before attempting to download the software.

    To prevent the non-standard extensions system to interfere, restart the Mac in Mode safe, before you try to install again, see: try safe mode if your Mac does not commissioning - Apple Support

  • VISTA and the new battery Bluetooth: no sound on headphones (Skype)

    Installation works very well. I can connect my headset is based. He said "plugged in and connected to Skype", but if I call someone, the sound always comes in my speakers and not via the headphones.

    Once, micro headphones listening, but now no longer works. I can press any button on the helmet, chance anything in the Options of Skyp... Nothing.
    With the old battery on XP the helmet has recognized as a Windows Audio device. He's not with the new battery. In Device Manager, two Bluetooth Audio devices are branded 'problem - driver issue '.

  • my laptop was preloaded and hard drive crashed. Do I have to buy a new drive to install the new hard drive?

    My laptop that I bought in January this year has been preloaded with windows 7 starter. I don't have the installation disc. What I have to buy one in order to install the new hard disk

    Have you given up on trying to resolve why the computer won't start? You will need to provide more information about what happens when you try to start the computer. There are several reasons for which a computer does not start and a damaged operating system is only one. Please describe in detail what happens when you press the button.

    Remember that a computer bought in January 2011 is very likely still covered by the warranty.

    In the event of failure of the BSOD (Blue Screen of Death) system, if that's what you see, for most users there is sufficient time to fully record what he says. the exact text is important for anyone trying to diagnose what is wrong. You can save time when the error occurs then by following the procedure described below.

    If you already did it disable the auto reboot system error. This should help by allowing the time to write the code to Stop error and related information correctly. Select Start, do a right-click on computer select Properties, advanced, system settings startup and recovery, system failure and uncheck the box before automatically restarting. Re-do not enable automatic restart in the event of system failure after obtaining this information, this setting is the best left to not allow an automatic restart.

    If the failure occurs during the initialization of the computer, you need to try a different approach. You can access the Advanced Options Menu of Windows on multiple computers by constantly pressing the F8 (key) key when starting and selecting the option - disable automatic restart in case of system error. This method is not always easy to use because it may be difficult to press the F8 key at the right time. Try again if it doesn't work the first time. On some computers, a different key must be used.

    You can get the computer to boot by following the advice in the following link:
