Re-installing quick launch button functionality on DV8T

Is there a particular set of installs which recovers all of the functionality of the HP Quick Launch buttons?
Here's the deal:
On a Pavilion DV8T-1000 CTO laptop, I've added a second hard drive, an SSD, which is in the primary bay.  The original drive is in the secondary bay.  Since the HP recovery media would not recover to the new SSD (slightly smaller than the original drive, so the recovery software gets pissy about it), I installed Win7 Pro from scratch, and loaded all the current drivers from the support page for this particular model laptop.
Most of the system functionality was returned, but I found that the quick launch buttons weren't behaving as I expected.  The wireless indicator didn't show blue (at all) when wifi is on, but did turn orange when it is off.  The mute button was always white, even when the computer is muted.  The volume didn't show the on-screen volume display.  The tone control would only show a goofed-up version of the on-screen display (bar area with random vertical lines which moved when I used the tone control slider).  The DVD eject button didn't work, and neither did the DVD play buttons.
Now note: I did do a quick launch button firmware update during this whole  upgrade process.  At first, I thought that might be the problem.  Then I put the original drive back as the boot drive, and found that most of the original functionality was still there (except for the wifi light still isn't turning blue when wifi is on... is only off).
I put the SSD back as the boot drive again, and started looking for things I might have missed.  I had the tone control software installed, and the quick launch button driver software.  Apparently that wasn't enough.  I found the SmartMenu software and installed it, and then I had the on-screen display working for mute, volume, and tone control... but the mute button is still always white (never goes orange when the system is muted).  And there is still no DVD transport or eject control.
Since this works with the original drive, this shows that this is not a hardware issue (otherwise, it wouldn't work for either drive).  It is obviously a driver/software/configuration problem.  But there doesn't seem to be one program or driver install which provides all the needed/wanted/desired function... not even two or three installs.  (and I still don't know why the wi-fi button isn't turning blue like it did before I did the firmware upgrade... which, unfortunately, I can't undo as older firmware versions aren't available to download).
How does somebody get all the original quick launch button (the capacitive button bar above the keyboard) back?

Have you tried installing the Quick Launch button software from the following weblink:

  • Quick launch buttons and touch functions not working post win7 upgrade

    I have several problems that I think are related.
    1) When I rotate the screen and then bring it close (as in flat) to the keyboard, the screen goes blank. There is no key combination I can find that restores the screen. Putting it back in notebook orientation doesn't do anything either. Only thing to do is a hard reboot.
    2) the quick launch buttons on the screen edge are not functioning as follows:
    a) the hp mediasmart button (the one with the wave) doesn't work
    b) the screen rotation button produces the same problem as 1) above
    c) the third button which looks like either gears or a sun (I don't know what it should do) brings up the windows mobility center, where I have found problem number:
    3) On tablet PC settings, the display tab, there is one display: 1. mobile PC display
    on the same tab, there is a setup button. The next screen says:
    pen input
    touch input
    Regardless which one I select, on the following screen (where it says Press this screen with ....) when I press with either my finger or the pen, nothing happens. Which seems like either:
    it thinks another screen is active or
    the touch components are completely non functional.
    4) Not surprising, the touch functions are completely non-functional
    I have installed all of the drivers for this TX2-1025dx for Win7(64bit) per the HP support/drivers page.
    Not all of them resulted in a clean install. 
    Here are other drivers that I had problems with (meaning that I got an error message, it failed, it had to be done more than once, something else broke, etc.)
    AMD AHCI  - started catalyst installer then failed
    Authentic fingerprint driver - "dpinst64 not marked for installation"
    Ntrig Duosense - had to do this one multiple times to get the fingerprint reader to work
    HP Mediasmart MVP - hung in CMD
    I have checked that all of the startup services are actually enabled in msconfig including quick launch buttons, hpwuschd, and media smart. Nothing is disabled in services.
    I have reinstalled the quick launch buttons driver for this product from December 2009. (There is an earlier version from November.)
    I installed the bios upgrade (before win7, actually) it is currently F.25
    I have also eliminated EMF possibilities.
    I have searched the forums, and while I have found some interesting clues, I don't see anything like this - at least with a solution.
    Any assistance would be greatly appreciated as this thing is quite useless to me as it currently functions. It is not a tablet anymore.
    TIA

    [knock knock] Helloooooo??!!??
    Installed 6.50.9.1, which is in between the last two quick launch button (QLB) drivers (that did not work). Also fixed the lightscribe and mediasmart DVD installs. Same problems, no touch or pen, and a new bug I discovered with qlb
    First, if you search for tablet in the start menu, there is a selection to set the tablet buttons to perform certain tasks. When you run that, it says that teblet buttons are not installed on this pc. Doesn't matter if QLB is installed or not - same error. Hmmmmm. Check with your pc manufacturer..... I think I am doing that. I am starting to feel like I am working for HP.
    Next finding: Using mobility center, I found that if you orient the screen to landscape for the slate config, and then rotate the screen, it does not go blank. However, if you rotate the screen back to notebook, it goes blank. And of course it keeps that upsidedown config when you reboot, too. So, the way to recover from that (because you really need a keyboard if you don't have a working pen and touch takes 30 sec to respond) is to keep trying to get touch to orient the screen back to landscape for notebook. Then rotate the screen to landscape for notebook. And uninstall the QLB driver that doesn't work and reboot. But after that, touch and pen did not function.
    Since touch and pen had previously been restored when I uninstalled QLB, I reinstalled MVP and smartmenu coz they were the actions that I took the last time before touch and pen returned. Didn't work this time, tho.
    I decided to do a system restore back at the point that I had used HP Advisor, since that was the last time I made note that pen and touch were working. Restore failed because a sfi.dat file was not found (and search didn't find it anywhere either). I tried 5 different restore points, before and after that one, and they all failed. But the first time around, I had touch on the logon screen, just not after windows started. The next time, I had touch but not pen. The next time, I had touch and pen, but only for a period of time (I think HP Advisor may have been the intervening event) before they stopped working.
    Oh, and HP advisor does not appear to be actually installing the things on the action list. That could be an issue with Comodo, but it really looks more like an issue with that "mother may I" message from Windows asking for permission to run the program. Often as not, windows reports that the program is not responding. Closing the program with that dialog box actually gives it the kick in the knickers it needs to complete.
    A not so great workaround is to use the mobility center to orient the screen when you want to put the thing in slate mode. You can pin it to the task bar (with a little fiddling).  Touch is extremely slow to respond in slate mode. For example, it took about 3 minutes to get the screen oriented back around to notebook config, which is 4 "clicks" if things are working right. Pen works sort of OK (although I haven't tried any writing) . Gestures for scrolling do not work.
    I am done with the troubleshooting until someone comes up with other targeted ideas.I have been keeping detailed chrono notes.
    Again, I hope the information here leads to a solution. This unit is not a functional tablet and I don't want to stay with Vista, neither should I have to since this is supposed to be compatible.

  • Sound quick launch button doesn't work when i installed windows 8 in my hp pavilion dv3z notebook

    when i installed windows 8 in my hp pavilion dv3z notebook pc, the quick launch button of volume is always red and the sound is mute....the driver for quick launch buttons and driver for sound is also up to date....can you please help me?
    This question was solved.
    View Solution.

    When installing the audio driver, was it installed by following the prompts or in compatibility mode as outlined here?
    Based on the Software and Drivers page for this unit, the unit was not tested and certified for Windows 8.  This means that some functionality may not be the same since the unit was not designed for Windows 8.  See this site for information and to find out if it has been tested for Windows 8.
    If the sound driver has not been installed in compatibility mode, then I recommend using the Windows 7 64bit driver found here and using the linked steps above to install it in compatibility mode.

    Hi lustyln,
    I'm having a little trouble understanding all of what you are trying to explain. From what I can tell, it sounds like your PC has a lot of software problems and you want to know what is supposed to be there and what isn't.
    For reference, here are your product specifications:
    http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&dlc=en&docname=c01893242&lc=en&product=4043282
    To get your PC software back to how it was when it was first purchased, run a system recovery:
    http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&dlc=en&docname=c01867418&lc=en&product=4043282
    I hope this helps.

  • Dv7-1130us - Quick Launch buttons not working - though they light up correctly

    I'm trying to enable wifi, though the quick launch buttons are no longer working. They used to work, though I've had my laptop repaired at the service center (to replace the keyboard), and I also immediately upgraded to windows 7 once my laptop was returned.
    I've done a hard reset, upgraded the bios, and upgraded the quick launch button drivers, though nothing is working. When windows boots, the wifi image on the quick launch bar transitions correctly as it has always done (blue to orange - since I had I usually had it disabled before I sent it in for repair and upgraded).
    Is there a way I can enable the wifi card without having to use the quick launch buttons? The wifi card has always functioned correctly when it was enabled, and it's working properly according to the device manager. I just need to either find a way to enable it without using the quick action bar, or get the quick action bar working.
    Any suggestions? I'd rather not send it back in for repair, it's a lengthy process.

  • Tx2 - Customize Quick Launch buttons

    I have installed Win7 Ultimate on my tx2-1370us (full / reformat) and re-installed most of the software, but... while the QLB seems to be functioning the Control Panel app doesn't appear to have been installed and I can't find a way to change the assignment of the buttons...
    any suggestions?

    I assuming by QLB you mean the 3 buttons on the montior (mine are windows moble center, hp media, and screen rotate) If you are id kill for these drivers I installed win7 from scratch as my upgrade has yet to arrive and everything worked great expect those 3 buttons. Without rotate tho my tablet is useless so I had to reinstall vista from a recovery disc (which was hell had to use my win7 disc to keep formating my drive but it finally worked) I was going to try and load the wim images with imagex and see if I couldnt find the driver but I dont even know the name of the program I'm looking for.
    Anyways this is the one thing keeping me from upgrading to win7 id really like a fix for this becuase If id known I was going to be stuck on vista id probably never have bought it :/
     also I can't find a quick launch button applet in control panel. 
    Anyone be kind enough to tell me the path? Thnx in advance

  • Quick Launch Buttons not working on dv7-3085dx

    Hello HP world.
    I am having a problem that I cant fix it myself and it is driving me crazy.
    I am very techy and usually always find a solution to any problem but this one got both of my feet locked.
    My Quick Launch Buttons on my DV7-3085dx  Running Win7 64-bit.
    Are not working. They were working fine since forever until 2 weeks ago I noticed the mute and wireless buttons remained red non stop? and they were not functionable. Almost as if they lost connection to the notebook.
    This is what i have tried so far:
    - Hard reset (after i did this the red mute button and wireless went off, now only volume and media controls are on, still useless)
    - Updating the QuickLaunch Buttons Driver
    - Updating the BIOS
    - Reinstalling MediaSmart
    - New Chipset Driver
    - Installing latest IDT driver
    - probably other drivers and such which i cant remember but its been over a week that i have been reading online and it came down to this.
    I surrender!
    Please help me.
    Thank you in advance.

  • HP Quick Launch buttons incompatibility Windows 8.1 / Unable to Launch IE 11 and my yahoo home page

    I have an HP Envy dv6 notebook PC Product # C2L31UA #ABA. I upgraded to Windows 8.1 several weeks ago and everything seemed to be working fine. About 3 weeks ago I started having problems with "internet Explorer stopped working" happening all the time. I also seem to have problems with installing updates from HP with failed updates then these problems start occuring.  4 days ago I was unable to launch IE 11 on my desktop or myyahoo home page.  IE 11 is not working on my desktop or from the tile on Windows for Internet Explorer. I am able to use google and have been trying to search for solutions. I did find out from a scan that HP Quick Launch buttons are incompatible with Windows 8.1. I thouhgt this might be the problems.  I have tried to remove it unsuccessfully. I have spent 4 days trying to fix my computer with no results. I thought I had uninstalled HP quick launch buttons late last night and I did briefly get my desktop to launch last night at 1 AM. However this morning It is not working again and the HP button is still on my computer. Not sure if this is what is causing all of these problems ? I also tried doing a system restore and it  failed also. Can someone tell me what I should do? Thanks so much! I am not very computer savy so I am getting very frustrated.

    Hello @luvpatch,
    I understand that you are not able to use the HP Quick Launch buttons after upgrading to Windows 8.1, and I would be happy to assist you in this matter!
    The first step I recommend is to completely remove HP Quick Launch from your system by using this Microsoft Fixit tool: Fix problems that programs cannot be installed or uninstalled. Once the program is removed, please restart your computer.
    To further diagnose Internet Explorer on your system, I recommend following Resolving issues in Internet Explorer (Windows 8), as well as Troubleshooting Wireless Network and Internet (Windows 8). This should help to re-establish a consistent connection between your notebook and wireless network.
    If the issue continues, I recommend performing a backup and refresh back to when Windows 8 was still installed on your system. To do this, I recommend following this resource on Backing Up Your Files (Windows 8), as well as Refresh Your PC to Resolve Problems (Windows 8).
    Please re-post with the results of your troubleshooting, and I look forward to your reply!

  • Faulty Quick Launch Buttons on my Pavilion dv9854ca notebook...

    I recently had to reformat my laptop after the hard disk failed to boot properly, and I had to reinstall Windows, and all the drivers and software I used before.  I installed the HP Quick Launch Buttons driver, and so far all of them (Play/Pause, Stop, Volume etc...I didn't install Quickplay because I don't need it) have been working properly except for the "mute" button, something I just noticed.  Every time I tap it, it will toggle to the other setting for a millisecond then switch back to what it was before, i.e. if there is sound, and I want to mute sound, I tap the button, and it will flash orange (signalling mute) for a brief moment before going back to blue (signalling sound), and vice versa.  Before I reformatted, if I wanted to mute or unmute, I tapped it and it would toggle to the other setting without switching back.
    Has anyone ever experienced this problem or know how to deal with it? It's nothing major but is a bit of a pain to have to click the windows volume settings...
    Thanks!

    You need to install sound driver to fix the mute issue.

  • DV7-1279WM microphone and quick launch buttons stopped working

    For some reason my quick launch buttons and microphone have stopped working on my DV7 laptop. I know that I recently used the microphone on a Skype call, but believe since that time that Vista SP2 was installed. I am not sure when the quick launch buttons were not working, but have just literally (talking less than a week ago) got the laptop back from HP for a warranty issue with the display. A strange thing I noticed is that if i look under the settings in Skype, the microphone will record a level for a split second, but then go back to nothing again (someone I was trying to talk to said they could hear me for a second).
    I thought it might be the same problems as in the 35 page thread on here, but I have sound, its only the microphone and quick launch buttons that are not working. So far I have rolled back, installed and updated sound drivers, BIOS and Quick Launch software, but no luck.
    Any suggestions? Thanks.

    Sometimes electrical components needs to have all power sources removed and reintroduced to work properly.  Try performing a hard reset first, if it doesn't work then we'll move to the next step.
    To Perform A Hard Reset
    Shut down the computer by going to the Start menu and selecting shut down. (If you have no display, hold the power button down for  5 seconds)
    Disconnect the AC Adapter from the notebook.
    Remove the battery from the bottom of the notebook.  There will be a switch/button to eject the battery.
    Wait at least 1 minute with all power sources disconnected.
    Re-insert the battery and reconnect the AC Adapter and then attempt to power on the notebook.

    Go to Control panel, software and verify that the programs are installed. Now uninstall them. After you have done that you can reinstall them from the HP Backup and Recovery manager. You can either do it from an F10 key during the startup of your laptop or from the HP Recovery CD set that you (should) have made.
