UML295 constant reset and blue led

So I've tried 2 UML295's now and having quite a bit of trouble.  At first I thought I just got a busted modem the first time around.  But after the 2nd one I'm wondering what is possibly going wrong.
The first time I used either of them, they worked fine.  Connected, got online, got good speed, etc.
Now they just appear to be in a constant reset loop over and over.  Device manager keeps chiming in that devices are getting plugged/unplugged over and over again.   On the UML295 itself the light is red for a bit, I see the devices start popping up in device manager, then the light turns blue for a while and the devices go away.
I've searched all over the place for the meaning of the blue light, but every doc VZ has on this thing describes. red, green, white & amber lights. Never does anything mention blue.
Any ideas?  perhaps firmware updates failed on these??
I've tried 2 different laptops (win 8.1 on a surface pro 2,  Win 7 on a Dell laptop and Win 7 on a homebuilt desktop) and all have the same results.  Card powers up, red led, DM chimes in, led turns blue, DM chimes out... rinse repeat.

  • Constant resets and freezes/ occasional blue screen

    I recently tried to go from iOS 7.1 to 7.0.6. After that, even after hard resets, the phone would work for maybe 30 seconds, then freeze up again. I restored my iPhone back to 7.1 and restored my backup and it still freezes. Now, it constantly restarts itself and just sits on the apple logo. Every now and then, it will flash a blue screen and then repeat the cycle of repeating and freezing. I am using and iPhone 5s.

    Did you go from 7.1 to 7.0.6 (downgrade), or upgrade from 7.0.6 to 7.1?
    This restarting problem was common with 7.0.6, and has been somewhat fixed with 7.1 (e.g., my iPhone 5S no longer crashes, but my iPad Air still crashes, though less frequently). Now my iPad Air freezes. I've looked around and there seems to be no readily available solution.
    If a restore doesn't solve the problem, you can either go to the Genius Bar and see what they say, or just wait for what seems to be another bug. I might backup my iPad Air soon and take it in since this seems to be a software/hardware issue. Sorry I really couldn't help, but I was surprised nobody has addressed your question.

  • What happen on my 4GS screen display.all the app are diappear and have the  background of the LED light inside the screen.can't see anything just only the line black and blue light

    I JUST HAD  A PROBLEM WITH MY IPHONE "4GS".THE SCREEN DISPLAY ARE BLANK.ALL THE APP ITS GONE.JUST HAVE ONLY "BLACK AND BLUE LINE"INSIDE THE SCREEN.ALL THE PHONE FUNCTION STILL ABLE TO RECIVED THE CALL BUT UNABLE TO MAKE PHONE CALL BECAUSE THE TAP ICON ARE GONE.

    Not sure what the origin of the problem is, but you should try deleting iDVD's preference files.
    First, close iDVD and go to your Home(YourUserName)/Library/Preferences/com.apple.idvd.plist
    Drag this plist file to the trash. iDVD will automatically create a new fresh one when you reopen it.
    Open iDVD.
    See if the main screen is now visible.
    Post back if that did not help.

  • Gaming 7 - flashing blue led.

    I recently build a computer and everything was working fine until yesterday when the computer wouldn't start. When pressing the power button normally nothing would happen but when pressed down for a while, a blue LED on the motherboard (under the MSI Dragon heatsink?) would start flashing and wouldn't stop unless the power cord was removed.
    Since then I removed all the components and tested them with another motherboard and everything works fine. Does anybody know what could be the issue?

    Like you wrote, my motherboard is the Z97-Gaming 7 and according to the manual it is for "BIOS A". The power and reset buttons on the motherboard are lit but nothing happens when pressed shortly. When I press the power button for a long time, the "BIOS A" LED starts blinking continuously but nothing else happens.
    OS: Windows 8.1 Pro - 64-bit
    Motherboard: Z97-Gaming 7
    CPU: i7-4790k
    RAM: 2 x 8GB CORSAIR Vengeance Pro 16GB DDR3 1600
    HDD: Kingston V300 240GB SSD + 8TB of various HDDs
    VGA: MSI Gaming Video Card - N760 - TF 2GD5/OC GeForce GTX 760
    Sound card: Creative Sound Blaster Z
    WIFI card: TP-LINK TL-WDN4800 Network adapter
    PSU: Thermaltake Toughpower 850W 80 Plus Gold
    Case: Cooler Master HAF Stacker 935
    All these components have been tested with another motherboard and they all work perfectly.

  • Solid Blue LED Indicator

    My Torch is displaying a solid blue LED indicator. My keyboard is not illuminating but I'm sure that's due to the light sensor being close to the LED. I've seen various items listed for this light; I do not have Bluetooth enabled; I do not have access to a music server. Between this and the freeze-ups after I unlock the device, I'm not happy here.

    a very frustrating problem.
    i dont  claim to have a solution but i'll tell you what happened to mine!
    first of all before the solid blue light came on i'd accidentally splashed the handset with water
    (nothing major, thought nothing of it, wiped it off and carried on.)
    the next time i looked at the handset the solid blue had appeared. gah.
    i spent several hours looking at web search results, tried all that hard reset and bluetooth on/off garb.
    no joy. got mad! dont have any trusted permissions for apps ive downloaded, dont have a music thing or any other bluetooth accesories either.
    so i was practically tearing my hair out and going up the wall with rage. decided to whinge about it on my friends
    facebook wall (via facebook for blackberry.)
    having vented my spleen sufficiently i closed facebook (not logout, just red buttoned it)  
    lo and behold - the blue light went off.  success. 
    no idea why it came on, no idea why it went off. just glad its gone now!
    i dont know if this will work for others but it would be interesting to know if anyone else had got their handset wet?
    wondering if it may literally be a case of waiting for it to dry out..
    its an ongoing mystery!
    good luck to all who suffer at the mercy of this blue demon..

  • WVC54GCA - blue led not working

    Blue led is not working on my camera. I did enable/disable led and also reset the camera but it seems that the blue led is dead!
    Anybody had the same problem?
    Thanks

    Try to upgrade/flash the Camera's Firmware, reset and then re-configure your Camera...
    Download Firmware 2.75 MB...
    After Upgrading the Firmware you should reset the Camera to factory settings and then re-configure the Camera from scratch...Hope this works...

  • TX2517ca, wont Boot - Blinking blue LED lights - Num Lock & Caps Lock

    notebook just decided NOT to boot one day..I can hear the fan and very minimal HDD activity. I've tried the Hard reset as directed by HP and removed the battery etc...  the lights blink exactly the same time, stay on for 1 sec, and the off for 3 seconds and then blink simultaneously again, and doesn't stop till I pull the power, there is no clicking, grinding, beeping nothing, nothing on the screen at all. The rest of the lighted buttons are solid blue.
    FYI, I am a computer technician of 15 years...home based at this time. so I have pulled the memory, cleaned them, 2 (1GB & 2Gb), compress air dried them and blue out the slots and reseated even by doing only 1 at a time, no change, same end result, blinking LED's. So I just pulled the Hard drive, connected it to another machine as an external HDD, it works fine, I can see the C drive and the Recovery drive without any problems. so at this point I have just pulled the battery from the board and will leave for a while to see if we can drain the BIOS/CMOS (wondering if software is stuck in hibernate or sleep and when powering on is only returning to similiar state, but wouldn't account for no screen display...) everything so far is pointing to CPU I would think. Next after replacing existing Hard drive and try booting if that doesn't work, I have a working blank Hard drive I can insert to try for the hell of it...stay tuned...
    Oh, also system is immaculate, no collected hair or dust in fan ports etc..
    This question was solved.

    Thanks
    Emmersond

    Dear Customer,
    Welcome and Thank you for posting your query on HP Support Forum
    It looks like your Notebook has a blinking/flashing CAPSLOCK light and a blank screen all the time
    Whenever the Capslock LED Blinks once that means CPU not functional and we need to replace the Processor
    However, I would request with you to perform the below shown step before contacting HP
    Step 01. Turn OFF the Notebook
    Step 02. Un-plug the Power/AC Adapter and also remove the battery too
    Step 03. Press and Hold the Power Button on the Notebook for a full minute
    Step 04. Test your Notebook with Battery and Power Adapter alone
    Note: If you are still facing the same issue try to remove and reseat the Memory Modules of your Notebook
    Hope this helps, for any further queries reply to the post and feel free to join us again

    I recently purchased FaceTime from the Application Store. After approx. ±10 meg, the application resets and starts downloading again. I have tried to download it at different times of the day but with the same results. I have been in contact with Apple support and have tried different options with the same result. I cannot download a new Version because in my Purchased List the applicaiton (FaceTime) is still there, and because I have halted it it tells me to resume. I can’t, because the same thing is going to happen. I have tried all the various troubleshooting tips supplied by my ISP and also Apple Support with no luck. I am currently working on a IMac OS 10.6.7. Has anybody got any ideas? Any suggestion would help. Thanks

    Also there is no activity on unit when I use the remote. The unit is stuck on the first page itself where we have to choose the language. The unit seems to be fine to me but the real problem is remote does'nt have activity. The IR is not responding while pressing any of the button.
    Good luck with your appointment.
    Not much consolation but even new products can have issues and might need a trip to a store to return/replace.
    The reason i asked about the LED on the AppleTV is that occasionally it thinks it's paired with a specific remote and ignores others - the unpair keypress I described is quick and free.

  • Cisco 1131AG LWAP status led yellow and other leds blinking green

    I have a problem with three AIR-LAP1131AG-E-K9  that joined the controller and the status led turns to yellow after joining the controller while other LEDs are blinking green.
    The APs has no coverage at all although the WCS shows that there is coverage and the 4400WLC shows that the AP interfaces are UP. (The ethernet interface and tha 802.11b,g radio interface is up).
    The SSID broadcast is enabled.
    On the switch the interface is up and there is traffic going in and out of the LAP.
    I tired power reset and factory reset for the APs but the problem remains the same.
    Any ideas for what might be the problem ?!!
    Regards

    Yes the clients are not able to see the SSID broadcasted by the AP.
    But these APs were functioning normally before without any changes to the WLC config.
    I had the same problem with other APs but they went back to normal state after a hardware reset to the APs.

    Use iTunes to do a reset to factory default condition. Always be sure to do your backups before fiddling with your iPad. You might do both the iCloud and the iTunes backup, just to be sure!

    keithfrommariettaOct 12, 2014 3:25 PM Re: IPAD2 very slow after IOS 8 upgrade
    Re: IPAD2 very slow after IOS 8 upgradein response to pacoKAS
    SOLVED:  IOS 8 Issues on iPad 2:
    I just returned home from a visit to the Genius Bar. Like you and many others, when I upgraded my iPad 2 to IOS 8, it became practically unusable. It was VERY slow, lagged whenever trying to to do anything. Lots of screen freezes and apps spontaneously crashing. I was convinced that the processor on the iPad 2 just couldn't handle the new IOS and I went in to see about restoring to IOS 7.
    Thankfully, I was hooked up with a very sharp guy at the bar. The problem is not with the OS, it is with it being an *upgraded* OS. He used the analogy of when you had an older Windows computer and how over time (and over upgrades), they just tended to get slower and slower because of all of the garbage that was carried forward in the upgrades. At those times (and if you've ever had a Windows computer, you get this), the only thing that would speed it up would be to wipe the machine and do a fresh install of the current OS and then reload your apps, and the viola, everything would be fast again. Well, it turns out that IOS can suffer the same problems.
    THE FIX:  FIRST, be sure you have a current iCloud backup of your device.  Connect your iPad to a computer that has a clean fresh copy of IOS 8 on iTunes (this is best done with a computer other than the one that you sync your device to because you DO NOT want to restore it from a back up just yet). Ideally, if you do this at an Apple store you'll be assured of the right version there and someone to answer any questions you might have along the way. You then hold the power and home button down to hard-reset the device and continue to hold them down until it reboots into recovery mode. You then follow the instructions on the computer to reinstall the OS on the device (which wipes everything from it and then reinstalls a clean copy of it). Once this is done (which only takes about 15 minutes), your device will reboot and ask you to set it up. Answer the questions about language, location, etc. and continue until it asks you to log into your iTunes account. Once you do that, it will ask if you want to either 1) Set it up as a new device, 2) Restore from iCloud, or 3) Restore from iTunes. Choose (2), restore from iCloud. This will ensure that it brings down "clean" copies of all of your apps and preferences rather than the potentially corrupted ones that might reside in your iTunes backup. That's it! It will take a few hours depending on how much data and apps you have, but I am happy to report that my iPad 2 is now running IOS 8 and it's running as fast as it ever did when it was brand new!
    To sum it up, this process 1) Wipes your device and the garbage causing your problems, 2) Loads a clean and bug-free version of IOS 8 to your device, and 3) restores your apps and data so that it looks just like it did before the wipe, with the exception that it works now!  :-)
    Note also that by following this process you don't have to go through the painful and laborious process of reloading all of your apps, data and/or settings. iCloud takes care of all of that for you.

  • 2005 iBook G4 lcd display has turned streaky fuzzy pink and blue

    Boot up laptop screen looks fine. Goes to sleep, wake it up, screen is now weird. Gone fuzzy, no true colors, looks streaky, pink and blue. I rebooted, no change. I'm plugged in, so it is not a power/battery issue. Since I've had this since 2005 I suspect I have to replace the screen, but heck I don't know. Can an expert help me here? I've got a screen shot to share, how do I upload it?

    O&O,
    I've got a screen shot to share, how do I upload it?
    I think to upload here you have to have a membership. I just upload pics on PhotoBucket:
    http://photobucket.com/
    It would help to see a pic.
    This is from the service manual for the 14" 1.42 GHz mid '05:
    "xScrambled or distorted video
    Check for video on external display.
    • If video is fine on external display, replace LVDS cable.
    • If video is scrambled or distorted on external display, replace LCD panel."
    That last line is a bit extreme AFAIC. I suppose a bad display could cause the GPU to put out distorted video. So if it was me I'd unplug the LDVS cable and then if the external display cleared up then I'd replace the LCD panel.
    The 1.42 also uses the ATI Mobility Radeon 9550 4x AGP I have one of these in a 1.33 12" and it went bad. My normal repair is to swap in a good chip from a PC laptop graphics card. Unfortunately I can't find a cross reference to that chip being used anywhere else but the iBook 1.33 and 1.42.
    after it was sleeping for 3 hours and the screen is bad again
    Have you tried resetting PMU? Does any of this involve moving the screen? That's one of my checks for a bad LVDS.

    Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
    Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
    You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.
