Elitebook 2760p Ericsson hs2340 WWAN device recognition problem in Windows 8

Hi,
I installed an ericsson hs2340 WWAN card in my Elitebook 2760P and it worked great, even in Windows 8.  Recently, I was managing my HP updates and flashed the bios update.  When the update was done my WWAN card was gone... well, mostly gone.  I can find it in device manager under "USB controllers" but it's in conflict (!).  There is apparently a problem with the device name (?) as I receive this message when I try to update the driver: "HP hs2340 HSPA+ Mobile Broadband Module USB Device" "The name is already in use as a service name or service display name" 
I've tried uninstalling the device and re-installing the drivers, checked the bios settings, and fixed the problem with "Telephony" services post-update (Control panel->Administrator tools->Services->Telephony->turn on WWAN, set to "automatic"). I'd rather not have to reinstall the OS if I can avoid it, and I'm not even sure it would be helpful.  Anybody with experience or advice?  Your assistance would be greatly appreciated.  Thank you very much.

Hello Mike_81,
Your EliteBook is a Business model.  Your issue would be best answered on the HP Enterprise Business Community Forum
Good luck!

  • Web Dynpro Java: Mobile Device Recognition Problem

    Hi, all!
    I' m building an WD App with different UIs for Mobile and Desktop usage and therefore try to get a com.sap.mobile.clientinfo.ClientInfo Object via:
    ClientInfoFactory clientInfoFactory = ClientInfoFactory.newInstance();
              ClientInfo clientInfo = clientInfoFactory.newClientInfo();
              IWDProtocolAdapter protAdapter = WDProtocolAdapter.getProtocolAdapter();
              IWDRequest request = protAdapter.getRequestObject();
              clientInfo.load(request);
    For this I added DC "com.sap.mobile.clientinfo" out of SAP_JTECHS as Used DC.
    When starting the Application, I receive the following error:

    Im a referencing the wrong DC in the wrong way? Any hints more than appreciated!
    Regards,
    Thoams

    Thomas,
    In your WD project right-click on project node, open "Properties", switch to "WebDynpro References" then select "Library References". Add here library <b>com.sap.mobile.clientinfo</b>
    If you add it in wrong place before, then remove it. If you add run-time dependecy for used DC, then remove it (just left build-time dependency).
    To find corresponding library/service in future, run Visual Administrator, find your service/library in Services/Libraries tree and copy the value of <b>Service Name</b> or <b>Library Name</b> respectively.

  • Elitebook 2760p sound problem'

    hi!
    i recently bought the new elitebook 2760p and it's great, except this problem that i'm having.
    The problem is that every once in a while when i'm listening to music, or watching a movie, the sound get's all scratchy for a second, and than it's ok. like it freezes for a second and returns to normal.
    my operating system is windows 7, recently installed. i have updated all my drivers, but the problem remains. audio freezes for a second.
    Any help from you guys would be much appreciated!
    Thanks!
    This question was solved.
    View Solution.

    Hi:
    If you have the HP Power Assistant software installed, see if removing that resolves the problem.
    If it does, and you want to have the software, go to your notebook's support and driver page, click on the power assistant software link, click on the revision history tab and install a very early version of it.
    If removing the software does not resolve the issue, you can reinstall the current version of the software.
    I wouldn't have any other ideas for you to try other than what I have suggested.

  • Zen Vision:M 30GB recognition problems...Big t

    Hi, 2 days ago i ran into a problem with my Zen. I had to charge it, as the battery was low and had to put some new music on it.. I plugged it into the USB port on my Laptop, where all of it's software is installed. The Zen wasn't recognized. Instead of the charging screen it normally started up with, it started up with the play screen(the screen it shows when a song is playing). I looked at the battery icon in the top right corner, and it wasn't doing anything. I turned the Zen off and started it up again. Nothing changed. I restarted my computer. Nothing changed. I shut down my computer and started it back up again. Nothing changed.
    I took it to my desktop computer, a Compaq, and tried it there. It worked, but not how i was expecting it to work. The battery icon started flashing with the little lightning bolt, acknowledging that it was charging. But the play screen was still there. The odd thing with this is, i left the player to charge for several hours. When i came back, the Zen was in some form of idle shut-down. The screen was black, except for the battery icon with the lightning bolt. Oddly enough, he battery bar hadn't filled up anymore than when i left it. Upon unplugging the player though, the Zen turned off. When i turned it back on, the bar had filled up more. It wasn't fully charged though.
    I plugged the cable back into it, and this time, the battery icon WASN'T charging. It just had the play screen on. It wasn't doing ANYTHING this time. Frustrated, i went out and bought the wall charger, and now i have a full battery. But it doesn't solve why my computer won't recognize my player.
    Today, i un-installed the software that came with the player and re-installed it. It didn't do anything. I installed the software on my desktop computer, and THAT didn't work either. So i came to the website here and used the trouble-shoot guide. That didn't help, and this is where my problem differs from the other posters here who have recognition problems:
    Back to my laptop: I have Windows Service Pack 2. I installed Windows Media Player . I went to the Device Manger, like the trouble-shoot guide said to. The kicker: Windows Portable Devices is NOT, i repeat NOT in my Device Manager. Neither does the Creative player either. I clicked on "The player does not appear in Device manager". That link showed me a diagram of a desktop computer, so went back to my desktop computer. I did everything above mentioned, and Windows Portable Devices is not in the device manager of my desktop computer either. Further reading the trouble-shoot guide, i could NOT locate "Other Devices" or "Unknown Devices" in my Device Manger on either desktop or laptop. There's nothing "Creative" related or "Zen" related at all in any of the Device programs.
    I don't know what to do. All of the trouble-shoot guides don't discuss my issue at all. Everything is "If an MP3 player is reported working properly in Device Manager, but it is not detected or listed in Windows Media Player or Creative Media Explorer..."
    Mine isn't even detected in Device Manager. My Device Manager has nothing regarding my Zen or Windows Portable Devices.
    I'm thinking about messing with it in Recovery mode, but i don't want to erase everything i have on here, just to have my player still not work. I'm going to try messing with this at my friend's house to check the cable and the player there too.
    But any help regarding my situation would be greatly appreciated. This is driving me crazy.

    I tried my uncle's Zen Vision: M 30GB on my laptop and strange things happened. My laptop recognized the player as an unknown device and said i needed to install the MTP driver. I did that, and upon doing so, my laptop recognized my Uncle's player as a Portable device, allowing me to transfer songs to his player. But it STILL doesn't recognize MY player. Email support says i have to send it in for repairs, but i don't know...
    Any luck with you?

  • How do I create a recovery partition on an HP EliteBook 2760p using Windows 7 64-bit Professional

    I have an HP EliteBook 2760p using Windows 7 - 64-bit Professional
    My original problem is that I couldn't create the Repair Disc
    I found out that the problem was with a file that was on the recovery partition
    I backed up the recovery partition from the same make and model computer
    I reformatted the partition and recovered the backup to the reformatted partition
    It didn't work
    How do I create the recovery partition  I have the 2 disks that came with the tablet PC

    If you do a factory restore using HP recovery discs it will put everything back including recovery partition. I don't know if any way to manually re-create the recovery partition.
    NOTE: back up your files as Factory Restore wipes ALL data.

  • MTP and recognition problems with Zen Mi

    Ok here I go, I have a 5 gig Zen micro.and here are my issues. I updated my players firmware a few months ago because it was running oddly. This worked beautifully and fixed the running oddly part. This was great until I got a new computer. I went to plug my player in and realized I did not have the proper software/drivers so i go to creative's site and download the ones I need. I finish all instillation stuff. I have media player . And when i plug the player in suddenly i get infinite recognition messages for an MTP device from windows. It keeps popping up until i disconnect the player at which time it says device installed but may not perform correctly. Ok so I realize something is wrong and I go forum trolling. I find people that say you need to downgrade media player from try that is still no go. I try to install different drivers. I try to install different software none of these fix the issue. On other computers i can get it to recongnize the player as a MTP device and load up. But as one of the fixes I went to the recovery mode and did a firmware reload. This went fine and the player still comes up and I can get it recognized but when I try to use the firmware installer (this is on other computers mine still does not fully recognize my Zen Mirco) It says device not found yet i can see it in my computer and it shows up as connected media device. I would first like to get the firmware reinstalled on my player. I can still goto the recovery mode screen. Then I would like help trouble shooting my MTP recognition problem.

    Ok well my I can load my player up with music with the old firmware. But for some reason I cannot use WMP because as soon as I update my current one I get the same error as before. So this is still an issue as I would like to be able to use WMP and I would also like to be able to use the new firmware but I think that will mess things up again also.

  • Western Digitial external USB drive recognition problem

    Hi
    I recently bought a Western Digital USB 250gb external drive. I connected it to my G4 Powerbook running OSX10.2.8 and it had no problem recognising it. I then dumped across a load of data successfully.
    A few days later I upgraded to Tiger and now the G4 won't recognise the external drive at all. I have scoured the forums for an answer but have found nothing to fix a drive problem where the drive just doesn't appear at all in disk utility (or on the desktop)!
    I didn't partition the drive when it was first recognised in 10.2.8 (which i now realise was a mistake). The data on the external drive is unimportant to me - I just want to be able to use the drive - maybe there's a way or reformatting and starting again? (The Western Digital site doesn't provide any drivers for Tiger - cos it's just meant to recognise it automatically..)
    Any information appreciated.
    Many thanks,
    Mark

    Welcome to Apple Discussions!
    Do you have any other USB devices connected to your Powerbook?
    Is this a recognition problem right after the computer boots up? Or had the computer fallen to sleep prior to your connecting it? Sometimes I've seen USB ports fall into a low power mode causing problems recognizing USB devices until the machine is next rebooted.
    If you have critical data on that drive, you may want to try Prosoft Data Rescue to see if it can see what is on that drive. You can also buy an external Firewire enclosure and try to move the drive to that, or find someone with a PowerMac G4 or G3 tower to see if it can be taken out of the case and put in the tower for recognition. If you do the latter, be sure that the jumper is set for the master/slave setting that matches the cable you are connecting in the drive.

  • Debian Linux character recognition problem

    Maybe this shouldn't be on this forum, but perhaps someone can help me...
    I have Jrun 3.1, java 2 1.4 and Debian Linux.
    On our test server everything was hunky dory, running perfectly.
    But once everything was on the real server, we've had a character recognition problem. All of the higher characters are just replaced by a y or a ?.
    I'm pretty sure that we can exclude java from the problem, the i18n.jar, which I believe holds all the international stuff is there and in the classpath (exactly as on the test server) and jrun is exactly as on the test server because we copied every folder as it was.
    Therefore I think we can bring it down to Linux (Debian).
    I cannot find where to look in Debian for any kind of keyboard or locale problem. Anyone know what to do?
    kbdconfig command doesn't exist on our system.
    Any help greatly appreciated.
    We are in Italy, by the way.
    Thanks.

    If you check out the default file encoding you'll find that it's 7-bit ASCII; no characters > '\u007F' come out as they should. This applies as well to compiling as to running.
    You can compile with another character encoding using the command line options, like: "javac -encoding ISO-8859-1 package/YourClass.java" (available at least in 1.4) and "java -Dfile.encoding=iso-8859-1 package.YourClass".

  • Hello.  I upgraded my MIFI 2200 (had no contract on it) to a Jetpack (with a contract) when customer service told me this 4G device would use less data because it was faster.  This was not correct.  Anyway, I got the device, had problems, did tech support

    I upgraded my MIFI 2200 (had no contract on it) to a Jetpack (with a contract) when customer service told me this 4G device would use less data because it was faster.  This was not correct.  Anyway, I got the device, had problems, did tech support, re-activated my MIFI.  1.  Decided to return the device. Spent hours with Customer Service, then finally up to Management, they agreed to take it back and void the contact, I sent it back immediately – and instead of voiding the contact they transferred it to my MIFI! Please cancel the contract on the MIFI. 2.  During the short time I had the Jetpack I continually received overage alerts, took it all the way up to 30 GB, each time I backdated the new data plan except twice when customer service did and failed to back date the increase, and once the computer locked customer service out and could not increase.  The end result is I have a $495 bill, many of these alerts were false since I ended up with only 14 MG for the month, etc.  I am asking that my bill be reduced significantly to reflect no overage and to compensate for these problems. Please open up a ticket for this.

    I had Verizon JetPak and you will find it will eat data like crazy. I opted to sign on to ATT Uverse and configured my phones and other devices to the WiFi on the Uverse system. It took about 5 minutes to completed the configuration.  I was using 10 to 12 GB monthly to support 5 devices. Even if you use Verizon DSL, you are still subjected to same GB allotment.  In my area, Verizon DSL is not available. With Uverse, I have 250 GB monthly to use, and I have not even come close to using anything of that magnitude. I reduced my GB package with Verizon to 2 GB per month and since having ATT Uverse, I never use more than 1GB a month with Verizon.
    I have no problem with Verizon cell phone service as we get a much stronger signal where we live than you can with ATT or any others.  It is just my opinion, but if you are running multiple devices off Verizon Jetpak, you will eventually spend a fortune to keep pace.  I pay $60 a month for 18 Mbps speed, although ATT have packages that cost much less. But, it saves me a bundle each month. The cost of Uverse alone is worth not having to run everything through a Jetpak.  
    If you have the  option to use another DSL service provider in your area, I recommend dumping the Jetpak and sign on with another carrier.

  • ATV2 and Airfoil recognition problems

    Hello all. I'm hoping you can help me out here... I'm running the new Apple TV and it's working fine through my wireless Airport Extreme. It recognises my computer and will play the contents of my iTunes library without any problems (and I'm liking it a lot!).
    However, I can't get Airfoil to recognise it. This is odd because I tried the free demo of Airfoil and it seemed to work fine but then I purchased a license (primarily to allow me to route Spotify through the ATV and into the home audio setup) and now the ATV just won't appear on the Airfoil list of devices.
    I realise that this is almost definitely an Airfoil issue and that that is a third party app but I'm not getting any joy from them and I know a lot of you use Airfoil - So I thought it worth an enquiry...
    Any ideas?

    Hi, I'm having the same issue although I have installed the latest update today. Could you be more specific about "fixed by the good people at Airfoil"? Thanks
    Update: Strange... I just checked it again and now Airfoil is showing one of my two ATV2. Really weird, however, is that iTunes now only shows my Airport Express and none of my ATV2s. From my iPad I can select all devices without problems.

  • Touch ID recognition problems

    I've been using Touch ID for over a week. I'm trying to figure out why it isn't working.
    The problem is that after I "enroll" my fingers (thumbs and index fingers), it works for maybe 5 or 10 minutes. After that, the sensor becomes extremely flaky and starts to fail to recognize any of the enrolled fingers.
    According to my best estimates, the phone only unlocks about 5% of the time. The rest of the time, it just says "try again" and forces me to eventually enter a passcode. I wipe off the sensor, dry my fingers, wash my hands to remove oils, etc. to no avail. A few times, it worked consistently (1 or 2 touches to unlock) for about an hour at a time before it became inaccurate again.
    I've tried removing and re-enrolling my fingers, but the same thing happens. I've heard a lot of stories about people using it and finding that it works relatively well, so I'm stumped on why it isn't working for my fingers. I called Apple and they didn't know enough to figure out why the sensor isn't working properly. My best guess had to do with temperature variations, but recent testing has ruled that out (I enrolled after washing and drying my hands, waited a half an hour, washed and dried my hands again, and it failed to unlock, all while being in a temperature-controlled room).
    If anyone else has had this poor performance and been able to determine the cause, I'd like to know. Please don't just post that "it works for you" unless you have some useful information.
    Thanks.

    I also had the touch ID recognition problem come up after the last update.  I did find that scrubbing the screen with the same finger used to access your phone may help motivate the sensor and actually works more often for me then not.  Try scrubbing the screen before placing the recognized finger on the sensor.  See if that works for you...

  • 5th Gen Recognition Problems

    I'm one in a list of many on these pages who appear to be having the same problem. I have tried all the fixes suggested vy Apple without success and I'm about to return the useless piece of crap to Apple in the hope that a new one will be more useful than the £300 doorstop I have at present.
    For anyone that has sent their iPod back to Apple and had a replacement sent, has this solved the problem? If not, has anyone been successful in having their money refunded?
    I'm concerned that returning the iPod will serve only to replace one with 8000 songs on it which is no longer recognised by my PC, with one with no songs on it which is not recognised by my PC. I've already spent 30 hours or so trying every conceivable fix with the gadget, and I'm concerned that there appears to be a very real - but unidentifiable - flaw with the product which seems to sporadically appear and make it impossible to update.
    Anyone had any good news when dealing with Apple on this front?

    Well, I now am back to 9000 songs and a couple of movies! How did I manage this given the recognition problems I've been having with iPod and Windows?
    Easy. Explained the problems to those nice people at PC World in Edinburgh and they gave me a Creative Zen Vision M as a replacement plus the £60 so of difference in price.
    So, back up to speed with my portable music and movies, and an FM Radio on it too. I seriously thought I had thrown my money down the toilet with the iPod and I'm delighted that PC World showed the sort of customer service they are not generally renowned for.
    Interestingly, they were saying that they have had a lot of problems with the iPod - particularly in recent weeks. I hope Creative don't go the same way!
