HP8570W with HP230W enhanced docking station does not recognize DMI connections

Hi,
I have an HP 8570W workstation with the HP230W enhanced docking station. I have three monitors plugged in - one VGA, and two DMI. Everything has been working for about a year. Suddenly today the desktop started jumping around and then the DMI monitors went dark. I checked in resolution and they do not show up anymore. I rebooted. I took laptop off docking station and retarted and plugged back in. I unplugged and replugged the DMI cable. Nothing helped.
Any idea what to try next?
Thanks,
SamBilbrey

    VB041AA#ABA 90w docking station does not charge my laptop when it is docked.  Is it supposed to? Should I look into a higher wattage power cord?

    Try a hard reset with the notebook. 
    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); (if the computer doesn't power on, move to the next step)
    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.

    My N8 does not recognize or connect to unsecured wifi network.  I don't know why but even my old N82 picks up unsecured wifi networks without a problem. 
    Does anyone know why?  I need help please.

    I cehcked both settings and none picks up unsecured wifi.  It only picks up 2 or 3 wifi networks in a range of about 14 wifi networks.

    Have you actually tested it out with an unsecured access point where your N82 sees it but not the N8.
    The only setting I can think of that could possibly cause this is Settings>Connectivity>Settings>Switch to WLAN, if you set this to Known Wlan's only, you need to first add this wifi as a new access point before you can use it with most apps.
    Yes, I have tested it with my N82 and my laptop also.  Both the N82 and the laptop pick up the unsecured wifi network but not the N8.  I checked the settings and even called for tech support but they couldn't even help me.  I was told that I they are going to look into it.  I might have to have to send the phone in for a replacement.

  • After sleep, retina MacBook Pro (Mid 2014) does not recognize usb connected mouse movement

    After sleep, retina MacBook Pro (Mid 2014, on 10.9.4) does not recognize usb connected mouse movement. I have tried a generic usb mouse and my Razer Deathadder usb mouse. Both mice work before sleep; but after sleep, the computer no longer recognizes mouse movement while still recognizing the mouse buttons when pressed. Any idea why this is occurring?

    Error message: "Ovi Suite/PC Suite does not recognize the connected phone.Ovi Suite/Pc Suite cannot read the required information from the phone.Check that the connected phone is supported by Ovi Suite/PC Suite".
    You can try this which can solve your problem.
    1. Disconnect your phone from PC if connected.
    2 .Open Control Panel and go to ‘Programs and Features’
    3. From the list of available programs, choose ‘Nokia Connectivity Cable Driver’
    4. Click on the ‘Change’ button on top toolbar. 
    5. In the setup dialog box that pops up next, choose ‘Repair’ and select ok. Wait for setup to complete.
    6. Restart the computer if prompted.
    7. Now connect your phone to the PC. Driver installation should complete and PC/Ovi suite (hopefully) should detect your mobile properly now.

    @ Omarbooyaka,
    Welcome to the forum! You should use Nokia Suite to update your device to Belle. If still the same, please go to control panel > printer and devices > right click the phone icon > remove the device. Then try to connet again. Also try all the steps provided by magovoru. Could you also report the issue here if connection still does not work.
    Hope this helps!

  • IMac G5 with OSX 10.5.8 does not recognize my Western Digital external drive containing the majority of my music library.  Is there any way to access that drive and recover the music stored there?

    I have an iMac G5 with OSX 10.5.8 that does not recognize my Western Digital external drive.  I had no problems with this until I upgraded to 10.5.  Most of my music library is stored on the external drive.  Is there any way to access it to recover the music?

    How is it connected?  Have you tried different port?  How about logging in as a different user then trying to mount the drive.

  • Nokia Updater does not recognize N91 connected via...

    My fone has gone loco on me of late.. freezes about 3ce a day, and after deleting EVERY thing on my phone memory without any improvements, i decided to get an update on the software. problem is, the new updater 1.02.03 or sumn.. does not recognize that my phone is connected, even though the new pc suite does when i try it out.. what could i be doing wrong? (yes, i checked, there is an update for the code my phone carries) thanks for the help (i hope i get..)

    Hi,
    I faced this problem, make sure you have the latest updater and the PC suite installed. The best would be to remove both from your computer and fresh download and install.
    Once you have installed it on the PC, now connect the phone (a PC suite is also installed on ur phone during the PC suite installation on the computer). I STRONGLY RECOMMEND THAT YOU USE THE CABLE THAT CAME WITH UR PHONE.
    Select PC suite from the phone.
    Start the updater as it is starting, u will see the prompt "Phone Disconnected from the PC suite" on your computer.
    Now it should (ideally) start the process.
    Cheers

  • Desktop Manager does not recognize USB Connection

    I have installed the Desktop Manager for MAC (v1.0.2) on my MacBook Pro Snow Leopard10.6.3.
    When I connect my Storm 9520 the Mac OS recognizes the media storage drives in the 'Finder'.  I can copy files to and from the device media using 'Finder' but the Desktop Manager does not recognize that the device is plugged into the USB (yes I have tried both USB connectors).

    I have an 8310, Macbook Pro running OSX 10.6 and the BB desktop v 1.0.2 build 8.  It recently stopped recognizing the USB connection as well.  I was able to sync my BB with the MAC but can no longer do so.  The MAC mounts the BB and I can access the SD card.  What gives here?

  • How can I get my HP desk jet 3054 to AirPrint with my iPad? It does not recognize any printer

    Bought new HP DESKJET 3054 printer, it air prints with my MacBook pro but not my iPad. It reads "no printers found" when I want to print. Can I get some help with this one ?  The iPad works on same wifi as printer but does not find printer. However it does work with MacBook pro .please help.

    Welcome to Apple Support Communities.
    Apparently your DeskJet is not on the 'official' list of AirPrint supported HP printers: http://support.apple.com/kb/HT4356
    If you don't mind tweaking OS X a bit, try the tweak in this thread, originally started in November 2010.
    https://discussions.apple.com/thread/2658720?threadID=2658720&tstart=0
    I'm successfully using it with OS X 10.6.7 and 10.6.8 and an iPad 2 using iOS 4.3.1 to a USB-connected HP LaserJet 1320 and a WiFi-connected Canon MP560.
    Note that with this modification, your Mac must be on and awake for iPad printing to occur.
    Others in the Support Communities use iPad printing apps such as Printopia. I've found that this tweak meets my needs, so I haven't tried any other apps.  Also check for an HP app for your printer, and make certain that your printer has the latest firmware installed.

  • Have a Panasonic PV-GS9 mini camera (tape)-newer computer with 10.7.5 iMovie does not recognize. Previous computer with 10.4.11 worked?

            Mar 28, 2013 11:36 AM   
    Have read a couple of "how to" downloads (iMovie'11:import video), followed the instructions with no success. Am using cable with firewire connector.
    Any ideas?
    thanks,

    Hi - my notes on this
    NO CAMERA or A/D-box 
    Cable
    • Are You sure that You are using the FireWire Cable - USB-Cable will not work for miniDV tape Cameras
    FireWire - Sure not using the accompany USB-Cable but bought a 4-pin to 6-pin (or 9-pin) FW one ?
    • Test another FW-Cable very often the problem maker.
    Camera
    • Test Your Camera on another Mac so that DV-in still works OK
    • Toggle in iMovie pref. Play-back via Camera (on <-> off some times)
    • Some Cameras has a Menu where You must select DV-out to get it to work
    • Camera connected to "charger" (mains adaptor) - not just on battery
    • Camera set in Playback mode - NOT Recording mode
    Does Your Camera work on another Mac ?
    Sorry to say it is to easy to turn the 6-pin end of the FW-cable 180 deg wrong.
    This is lethal to the A/D-chip in the Camera = needs an expensive repair.
    (Hard to find out - else than import/export to another Mac ceased to work
    everything else is OK e.g. recording and playback to TV)
    A/D-box
    • Is the dip-switches set right ?
    • Set to same standard as recorded/editing e.g. NTSC 29.97fps or PAL 25fps
    • Try resetting it
    Connections
    • Daisy Chaining most often doesn’t work (some unique cases - it’s the only way that work (some Canon Cameras ?))
    Try to avoid connecting Camera <--> external HD <--> Mac but import directly to the Mac then move
    the Movie project to dedicated external hard disk.
    • FireWire-port - Can be re-setted by - Turn off Mac and disconnecting Mac from Mains/Power for 20-30 minutes
    External device’s (hard disk’s)
    • Should be FireWire as USB/USB2 performs badly and so does Airport or Net-work connected ones too.
    • MUST BE - Mac OS Extended formatted - UNIX/DOS/FAT32/Mac OS Exchange - DO NOT WORK for video due to 4Gb barrier.
    Mac
    • Free space on internal (start-up) hard disk ? Please specify the amount of free space.
    (Other hard disks don't count)
    I go for a minimum of 25Gb free space for 4x3 SD Video - and my guess is 5 times more for 16x9 HD ones
    after material is imported and edited. No Camera or A/D-box
    • GarageBands fix - Close iMovie, Open GarageBand, Play some notes, Close GB and iMove can now be OK
    • Does Your Mac have a FireWire Port
    • White MacBooks - don't
    • MacBook-Air - don't
    if not then a few Mac’s has a PCM-CIA slot and there are FW-Cards that makes a FW-port this way
    else - NO SOLUTION
    Only option as I get it is either
    • Use another Mac to Capture material (to an external USB2 - Mac OS Extended formatted hard disk - or -
    • Change to another Camera that can be used with Your Mac (no there are no miniDV tape Cameras that can)
    • If Your Mac-Book has a PCM-CIA Card place - then there are FW-port-Cards and then
    You can import via this - but I've not seen this on more modern Macs. My PowerBook G4
    has one and this FW-Card-port works greatly.
    SoftWare
    • Delete iMovie pref. file may help sometimes. I rather start a new account, log into this and have a re-try.
    • Any strange Plug-ins into QuickTime as Perian etc ? Remove and try again.
    • FileVault is off ? (hopefully)
    • Screen Saver - OFF
    • Energy Saver - OFF
    Using WHAT versions ? .
    • Mac OS - X.5.4 ?
    • QuickTime version ? (This is the heart in both iMovie and FinalCut)
    • iMovie’08 (7.1.?), 09 or 11 ?
    • iMovie HD 6 (6.0.4/3) ?
    Other ways to import Your miniDV tape
    • Use another Camera. There where tape play-back stations from SONY
    but they costed about 2-4 times a normal miniDV Camera.
    • If Your Camera works on another Mac. Make an iMovie movie project here and move it
    over to Your Mac via an external hard disk.
    (HAS TO BE   Mac OS Extended   formatted - USB/DOS/FAT32/Mac OS Exchange WILL NOT DO)
    (Should be a FireWire one - USB/USB2 performs badly)

    Hi Bengt W, I tried it all, but nothing worked. Your answer has been helpful insofar as all the different trials led to the conclusion that there was something wrong with my iMovie software. I therefore threw everything away and reinstalled iMovie from the HD. After that the exportation of DV videos (there has not been any problem with HDV videos) to my Sony camcorders worked properly as it did before. Thank you. LKN 1935
    from Karsten.
    in addition to Bengt's excellent '9 yards of advice' ..
    camera set to 'Play' , not rec/computer/etc.?
    camera not on battery, but power-line?
    did your Mac 'recognize' this camera before...?
    a technical check.
    connect camera, on, playback, fw-connected...
    click on the Blue Apple, upper left of your screen ..
    choose 'About . . / More . .
    under Firewire.. what do you read . . ?
    More
    • FileVault - Secure that it’s turned off
    • Network storage - DOESN’T WORK
    • Where did You store/capture/import Your project ?
    External USB hard disk = Bad Choice / FireWire = Good
    If so it has to be Mac OS Extended formatted
    ----> UNIX/DOS/FAT32/Mac OS Exchange is NOT Working for VIDEO !
    mbolander
    Thanks for all your suggestions. What I learned is that I had a software problem. I had something called "Nikon Transfer" on my Mac that was recognizing my Canon camcorder as a still camera and was preventing iMovie from working properly. After un-installing Nikon Transfer and doing a reboot, everything worked great.
    I never liked the Nikon Transfer software anyway--I guess I'll get a cheap card reader and use that to transfer photos in the future.
    No Camera or bad import
    • USB hard disk
    • Network storage
    • File Vault is on

    The problem was the external backup hard drive that is connected, you need to disconnect the external drive before the mac can see the video camera.

    Maybe your problems is solved in the meantime, but for all others this might help as I had the same problem, also have the Sony HDR-HC7, but the 7e (Europe, PAL). I found this link today and it works perfectly
    //support.sony-europe.com/tutorials/dime/videotransfer/vtransfer.aspx site=odw_en_GB&sec=DVH&m=HDR-HC7E
    What I exactly did.- put camera in play mode - open guide - choose connection guide - choose comp./printer (where to transfer movie to) - select connection.- i-link (on my camera) but equal to firewire - OK - choose HDV - choose NO for conversion of i.link.
    Settings are shown then (VCR HDV/DV.- HDV and i.link-conv..- OFF), press OK, OK, END.
    Switch camera off. Connect firewire cable to camera & Mac. Switch camera on, in play/edit mode.
    Open i-movie, choose import from camera. On screen below the camera connection is shown.- DV (HDV). Now you can import, automatically or manually.
    This worked perfectly for me. Took me 2 days to find out. Could not find any clear thread explaining what I had to do on the camera and the manual was not clear either.

  • Aperture does not recognize Internet connection with SmugMug

    When I try to add an account for SmugMug, the Accounts dialog box shows, "Your computer is not connected to the Internet. Aperture needs an Internet connection to login to SmugMug."
    I added a Flickr account with no problems. How can I get Aperture to recognize that I have an Internet connection for SmugMug?

    ** Workaround **
    The problem appears to be with some routers in the network -- for example my Netgear R6300. When I hooked my iMac (running Mavericks) directly to the cable modem with an Ethernet cable, Aperture was able to authenticate with the SmugMug service (using Safari). The Apple Professional Applications technician suggested trying that, and it worked.
    After replacing the original network configuration, where the iMac is connected through the Netgear router, Aperture maintained the SmugMug shared service, and I was able to upload and download photos with SmugMug.
    Confirmed that this insane workaround did work. ***, Apple and/or SmugMug? This should be fixed. It doesn't jive with Apple's "ease of use" software mantras.
    BTW -- I have a Netgear WNDR4500 v1 in between the world and my Mac.
