  • ITunes Not Working After Windows Upgrade from Vista to 7

    I recently upgraded a laptop from Vista to 7.  iTunes 7.x was installed before the upgrade.  As soon as Windows 7 was insatlled I upgraded to the lates version of iTunes(10.x).  After the upgrade I had some issue where I was getting an error about artwork and iTunes would not open.  I renamed the artwork folder to old and then I was able to get into iTunes.  The next problem that I am running in to is that any time I click on a task such as find music iTunes stops responding and crashes.  I've tried new config files, completely uninstalling and reinstalling, clean booting, etc. with no luck.  Anyone have any suggestions?

    I've been working on this issue for 2 days with no luck.  Still looking for a solution if anyone has one.  Thanks!

  • Help on small issues after WinXP downgrade from Vista

    Lenovo 3000 v200
    I recently downgraded from Vista to WinXP Professional, and I must say I'm much happier with XP.
    Some issues on the install: although I downloaded all drivers from the Lenovo site, the install didn't work from my usb floppy drive.
    It recognized the floppy on the F6 portion of the install, but then later it kept asking for the disk to be inserted (it was already in the drive).  Workaround was to install by changing to "compatibility mode" in the BIOS, and after install, loading all drivers and changing BIOS back to SATA.
    All features of the laptop appear to work perfectly; camera, fingerprint reader, wifi, etc.
    HOWEVER: in the device manager, there are 3 yellow exclamation points in the "Other Devices" section, and each of them is labeled "Base System Device."   Does anyone know what these are?  Why are they not recognized as specific devices?  LenovoCare doesn't recognize them either, and I have no idea what drivers to attempt to install for mystery devices.
    Also, "Modem Device on High Definition Audio Bus" won't install.  I have the current driver, and I've tried updating from LenovoCare, but no luck.  As I don't use a modem, this seems irrelevant, but I'd like to install it just the same if possible.
    Finally, the LenovoCare recognized a need to install a "Hotkey" update, and it claims to successfully install, but everytime I run LenovoCare it says I need it again.  Any comments or observations?
    Again, the computer works just fine even with these small issues.  In fact, it is better than fine; it is a joy to use and a real speed demon with XP instead of Vista.  So I'm not trying to do any rocket science or potentially screw up a very nice situation, but I am trying to iron out these small nuisances.
    Thanks to all of you who consider my trivial problems.  I really appreciate having knowledgable individuals like yourselves help out a very modestly skilled, but reasonably ambitious user.
    Cheers,
    Fred

    Hello Fred,
    I created a blog on this forum called.... "I Explain How To Downgrade From Vista To XP Successfully On A 3000 N100 Laptop" Locate this message and read through it. Try the "Auto Detect This System" I Talk about. It will load the latest drivers and the latest...BIOS..... for your particular model if you have not already upgraded it. You did not mention if you had upgraded your BIOS...... if your running an  "OLD" version.... THIS..... could be your problem.

  • I can't use my USB ports or connect to the Internet after downgradin​g from Windows 8 to 7

    I downgraded my HP Pavilion p7-1534 desktop computer from Windows 8 to Windows 7 today with a Windows 7 Home Premium disk I purchased. I checked online first to see everything I'd need to do, including backing up all my personal files and information to an external hard drive and downloading all my drivers to a USB drive.  I followed online instructions and went into the  UEFI bios settings and disabled Fast Boot and Secure Boot and enabled Legacy mode.  Windows 7 finally loaded and it comes up.   However, my PC now no longer recognizes that I have several USB drives so I can't load my drivers. Also, I can't connect to my MediaCom cable Internet.  Does anyone know what I did wrong and what I can do to fix my PC?

  • Catch 22 after Win7 upgrade from Vista (no way to install Boot Camp)

    I've seen other posts about this but no answers, so I'll keep this
    I had Vista Home Premium running in a Boot Camp partition on my black MB 2.0GHz with Snow Leopard, although I only used Fusion and not Boot Camp for Windows. (The Boot Camp partition dated back to the program's beta, which I ran on Tiger. I skipped Leopard.) I replaced the hard drive with a larger model -- thank you CCC and WinClone --, upgraded to Win7 Home Premium and thought I'd try getting Boot Camp running.
    The Snow Leopard install DVD has a Boot Camp 3.0 installer that refuses to run on Win 7. (The error message that I get is, "Boot Camp requires that your computer is running Windows XP Service Pack 2 or Windows Vista.") And the Boot Camp 3.1 Updater is, well, an updater that wants to see Boot Camp 3.0. Doesn't seem to be any way forward!
    I've seen it recommended to try a Boot Camp 2.1 installer (seems like a long shot, but has anyone tried it?) or to run the Boot Camp 3.0 installer in Vista compatibility mode (reported not to work).
    It doesn't feel worth it to re-image the MacBook's Boot Camp partition to Vista using my WinClone backup, then install Boot Camp 3.0, then do the Win 7 upgrade again, and then run the Boot Camp 3.1 updater. Not when Fusion is so good. It took me several iterations of the restore-and-upgrade business with Boot Camp Assistant and WinClone to get to this point and I'm not eager to repeat it. It's not hard, just tedious. It does seem likely that that upgrade path would work, however. Practic makes perfect.
    Thoughts?

    And just one more thing... I'm remembering now that when I started up the Win7 install, I got a warning that Boot Camp wouldn't work after the upgrade. I don't know which version that would have been. I went ahead with the upgrade anyway. Knowing now how that worked out, I can see that I probably zigged where I should have zagged. But I remember thinking at the time that my options were to cancel the upgrade, uninstall Boot Camp and then try the upgrade again. It didn't occur to me to upgrade to the 3.1 version of Boot Camp because I thought that was the Win7 compatible version, and I was still on Vista at that point.
    Maybe all this verbiage will help someone else avoid this situation!

  • Upgraded window from vista to 7 on pavilion DV7 sound not working

    Pavilion DV7 1468NR upgraded windows from vista 64 to windows 7 64 sound not working

    Hi,
    Try the following.
    Download the IDT Audio installer on the link below and save it to your Downloads folder.
    http://ftp.hp.com/pub/softpaq/sp45001-45500/sp45073.exe
    When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers.  Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
    When complete, restart the notebook and let Windows fully load.  Open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation.  When this has completed, right click the speaker icon in the Taskbar and select Playback Devices.  Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button - check if you now have audio.
    If you still have no audio, open windows Control Panel, open Administrative Tools and open Services.  Check that the following services are all showing as Status= Started and Start-up Type= Automatic
    Audio Service
    Multimedia Class Scheduler
    Windows Audio
    Windows Audio Endpoint Builder
    If you need to make a change to any of the above, just right click the service and select Properties, then in the dropdown box next to 'Start-up type',  select Automatic and click Apply to save the change.  Then click the Start button.

  • HP Pavilion Laptop; Only Special Function Keys are Working

    I got my first HP laptop, a HP Pavilion 17-e049wm Notebook, refurbished a few months ago when my original quit out. Until recently, I've been more than happy with its performance. However, a few weeks ago the keyboard started acting both weird and also not working. I'll try to provide as much information as I can, and thank you in advance for your assistance!
    Circumstances before the event:
    -The night before, my keyboard worked one hundred percent fine. I played some games and went to sleep with it closed and hibernating like I always have. The next morning, I took it up with me to play music as I showered. Before I'm accused of water-damaging it, my laptop was very far from shower, so no direct water contact occured, and also we shower with the door open, so there was no build up of steam or humidity that could've done it that couldn't be present in any other situation. I knew that it worked that morning, as I must have logged in to play my music. After closing it and bringing it to my car (without drops or any other jarring), I learned a few hours later that my keyboard had stopped working. 
    -My house doesn't have internet and I havn't recently installed anything, so it's doubtful that some kind of software did it to me.
    What the keyboard does(n't do): 
    -Almost every key doesn't work. The letters, esc, enter, shifts, fn, numberpad, caps lock, etc. I've tried them each, and none work.
    -There are two exclusions to the above statement:
         -The 'special' function keys; All of the keys that share space with my function keys work fine. So my mute, pause, change display, brightness controls, help shortcut, airplane mode, etc. work. So everything from F1 to F12 work.
              -Before anyone assumes that my fn key is stuck or something, the special part is the default. On my keyboard, you hold down the fn key to do the normal fn key functions (f11 skips to the next song, fn+f11 does fullsrceen).
              -Also, I'm not sure if my 'normal' functions work. I tried holding fn on this USB keyboard and then the f# keys, but the 'special' function still is the one that works. However, as I have no control, I don't know if that would have happened anyways.
         -The second exception, which makes me doubt that it is a hardware problem, is that if I hold 'X' and 'C' at the same time, the brightness lowers, as if I tapped my f2 key. Each of those do nothing on their own, but when pushed together, they act identical to the f2.
    -Another thing is that my ported keyboard's caps lock indicator light still shines when either the USB or on-screen's caps lock keys are used.
    What I've tried:
    -Turn it off and back on
    -Turn it off, take out battery, hold the power button, wait, turn on with/without battery
    -Uninstall keyboard driver, restart
    -Summoning a demon 
    -Tried to update driver (can't, up-to-date)
    -Check status through device manager (claims that it's running fine)
    I've basically tried everything I could find that seemed relatively useful from browsing the forums, but it's on my third week keyboardless, nothing works, and I'm so tired of using my girlfriends pretty, sparkling and bedazzled, purple USB keyboard from her days in middle school. If nothing works, I'll have to resort to the system resets and lose applications and my files, which would be a mad bummer yo.
    Thank you again for your help, internet. 

    @cbowman08 ,
    Hello and thank you so much for posting on the HP support forums. Now please I am not stating you have done anything wrong in any way.  This kind of thing happens all the time. 
    You do not need a bunch of steam to cause an issue with water for one thing.  
    Inside your notebook is a huge differential in temperature zones.  If you take a notebook into a shower room even if your water is slightly above room temp there is ample moisture in the air. 
    Air has to travel and if your notebook was on the counter and it is between your shower and the door, any moisture in the air gets to get heated way up and then gets to cool way down and gather on the little metal bits in your notebook.  
    It only takes one drop of water the size of a pin head to bridge a connection and cause a short.
    I hope this is not the case.  I am hoping that the connection cable for your keyboard has come loose.
    So to see if this is just a loose connection instead of a bit of moisture causing the issue here is a link to your maintenance guide,
    Maintenance and Service Guide
    This will show you have to get your system apart to check they keyboard connection.
    As well here is a link to how to gain access to the keyboard and its connection.
    HP Pavilion 17 Replace Keyboard HDD SSD Ram New Model Laptop.
    Check to make sure the keyboard cable didnt just come loose.  Very easy fix.  If it is connected and nothing is loose then you are looking at a replacement keyboard or if the board did get some moisture on it from condensation then you will need to have it sent in for repair.
    If that is the case you will want to contact phone support for repair options.
    Please call our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region. http://www8.hp.com/us/en/contact-hp/ww-phone-assist.html
    I am hoping for the keyboard connection coming loose here.
    Have a great day and thank you again for posting let me know how it goes.

  • Crossing HP Pavilion laptop with Vista to Toshiba NB205-N210 with XP? Usefulness of Bluetooth.

    Is there a conflict in crossing over files from HP Pavilion laptop with Vista to Toshiba NB205-N210 with XP? Is Bluetooth necessary (or useful) on a Toshiba? I have Bluetooth on my Hp Pavilion.

    A crossover network cable is one that is designed to connect two computers to each other through the LAN port without using a router.  It sounds like you don't have any sort of home network to work from or have any experience in networking.  Instead of wasting a lot of time posting methods that you might not be able to use why don't you start by telling us what networking methods you have available, if any. 
    Also, do you have an external USB hard drive?  That might be easier to use for this. 
    Lastly, how much data are we talking about?  That would have a large bearing on how we should go about this.
    If you don't post your COMPLETE model number it's very difficult to assist you. Please try to post in complete sentences with punctuation, capitals, and correct spelling. Toshiba does NOT provide any direct support in these forums. All support is User to User in their spare time.

  • T410 - sound cuts out during playback, resumes after pressing volup or voldown

    hello, I am using T410 with Win& x64, more more than 2yrs. Last week the sound playback issue occured. This happens with video and audio playback of any file type. After 2-3 mins of normal playback sound cuts out, but resumes right after I press vol up or down. Then after 2-3 mins it cuts out again and so on. I dont believe its a software -related error, since sound does not play even with Knoppix Live CD. Latest drivers and BIOS updates are properly installed. windows sound test finishes succesfully. I have read similar posts but all were related to software configuration. I have also replaced the speakers without change. Is there a known fix, or even a fix at all? Thanks

    Yes, videos, music, online, off-line and even window sounds, all audio turns off.  Sometimes messing with the volume slider or mute button will bring it back on but eventually neither of these work and I have no audio period until I restart the computer and then the cycle starts over.  For my business I create informational short videos or audios and use internet calling.  I also attend trainings and meetings online.  Sound cuts out first every few minutes and gradually increasing until it will not come back on at all.  I purchased a small bluetooth speaker and use that but it is a pain to move, along with the laptop, when I am moving from one room or location to another.  Thought it would be a temporary solution until I could get the internal speakers working but since that is unlikely to happen purchased clipon speakers to make it easier to transport.  This is not some off brand, $350 computer but supposedly a quality business computer, which is what I paid for but did not receive.  As I said, I have searched the internet and found hundreds of post regarding this problem on both 410s and 510s.

  • HP pavilion laptop Dv6000's internal drive is dead

    My HP pavilion laptop Dv6000's internal drive is dead, I need to replace it.
    It is a WD Scorpio WD 1200B EVS - 60UST0 120GB.
    This disk is not manufactured anymore. Do you know which disk I should buy?
    Thank you.

    Hi:
    You can probably get by with any 2.5" notebook hard drive 250 - 500 GB on your model series.
    Keep your old drive as you will need to transfer the caddy, connector and screws to the new one you get.
    Some suggested replacements...
    7,200 for best performance (slightly less battery time between charges over a 5,400 RPM drive).

    You will also need a set of recovery disks which you may be able to order by reading the info at the link below:
    http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph07143&cc=us&dlc=en&lc=en
    If your PC came with windows vista and you can still read the whole product key on the bottom of the PC, you can make your own Vista installation disk as follows:
    If you're up to a slight but rewarding challenge you can make your own if you can read your 25 character Vista product key on the PC.
    Just download the 3 files you need at the link below, and read all of the instructions to create a bootable DVD installation disk using imageburn.
    Disregard the part of the text under the first screen shot about "extract the files to the Vista folder."
    The files were already extracted to that folder when you ran the X14.exe file by reading the text on top of the first screen shot.
    The other thing I noticed is on the 4th screen shot, where it shows Developer ID Microsoft Corporation. I had to type Microsoft Corporation in myself, and then the other codes automatically populated.
    When I went to compile the ISO file, ImageBurn gave a message that about a WIM file and ISO, and if I wanted to burn it in a different format.
    I selected No, make the ISO file.
    It was not that hard to do. I burned both the 64 bit disk and the 32 bit disk in case I ever need them.
    I tested both of them an my hp dc7100 CMT desktop PC, they worked perfectly.
    When you enter the product key, it knows what version of Vista you have.
    http://en.community.dell.com/support-forums/software-os/w/microsoft_os/3317.2-3-microsoft-windows-v....
    After you successfully install Vista, you can then install the drivers from your PC's support and driver page.
