HT2810 LED BLINKS FAST-SLOW-FAST

A power cut in our area meant that I took my Macbook Pro elsewhere to work.  When I returned and reconnected it to my Cinema Display I was unable to get a picture.  Other posts seem to suggest that the blinking LED indicates a failed 90W power adapter and that it is not uncommon.  If this is true I am shocked to find that Apple supply the display and its power supply without a warning that this can happen and advice on how to avoid it.  I have checked the User's Guide and verified that there is no such warning and there is no mention of it on the Apple support page for displays. Before I spend money on a replacement can anyone confirm that there is no reset procedure that retrieves the function? I also need to know if the display itself is likely to be affected and whether Apple can be held responsible for supplying equipment that cannot handle something as common as a power supply interruption.

Trying to figure it out myself. It seems random. I can have multiple missed call notifications and it always slow blinks. Multiple text notifications = slow blinks. But mix any of those and I get fast blinks. But 1 missed email = fast blinks. Seems like no reason for any of it. Maybe I am missing something.
Just glad we have the LED notifications though.

  • WRT54GP2 not working - Power LED blinking fast.

    My WRT54gp2 has been working without issues for 2 years. All of a sudden from yesterday, the power LED is blinking fast. I am not able to connect to the web interface. My computer says limited or no connectivity. The internet and WAN LED are steadily lit. Has anyone faced this issue ? Is my router brick now ?

    As the power light on the router is blinking..It means that the firmware of router is corrupted..Check this link to unbrick the router.

  • Why am I not seeing the LED blink faster on hardware when the waveform graph shows the signal updating?

    I am using the cDAQ-9188 chassis with a NI 9476 in the 8th slot, and when I run my VI, the waveform gets updated if I change the frequency of a signal while the program is running, but the DO from the write does not get updated. I thought that write takes in the data from the digital waveform input, so I'm confused as to why the digital waveform indicator is updated with a new signal, but my LED into a DI module (9421) is not updating.
    Thanks in advance for any tips and suggestions!
    Speed2.vi calls Generate_PWM.vi, so Generate_PWM is a subVI inside Speed2.

    Hi Ruthnan,
    Sorry for the delay in response but after looking over that hardware it seems there should be enough counters in the chassis to support what you are doing. I believe you are getting the resource is reserved error because you have started one output task on that module thus reserving the reference. Once that task starts any additional task with get an error. It should be possible to use more than one counter in your application but it sounds like an error in the VI configuration. I am happy to help here to get an example up and running but I think it would be faster to open a service request for this issue. Let me know what you would like to do.

  • Satellite A10: Battery-LED blinks with AC

    Not too long ago I bought a new battery for my notebook. About a half year it worked well. But one day I couldn't start the notebook without AC. I thought, the battery was simply discharged. So I set up the AC-adapter, but the next time, the notebook didn't start either. With AC no problem.
    So I charged the battery, and when Windows said, Battery Full, and the LED was green, I disconnected the AC. But then, the notebook fully stopped, as if there was no battery.
    Now it is this way: it doesn't matter what Windows sais. The Notebook doesn't start without AC. After a disconnection of AC, the battery-LED blinks fastly orange. When windows runs, it only blinks slowly orange.
    Where is the problem? Does anyone know a solution?

    Hi
    In my opinion there are two possibilities.
    Either the battery is dead and must be replaced or the notebooks power supply electronic malfunctions.
    The first possibility is not serious problem because the battery replacement should helps to solve this issue but if the notebooks power supply electronic does not work properly, the whole motherboard should be replaced.
    I think its advisable to contact the ASP in your country because the guys could locate the fault very quickly and could provide the best solution.
    Good luck buddy

  • D-leds just blinking FAST, no boot!

    Hi!
    I have a MSI 815EPT PRO system, P3 server 1.4GHz processor, 384MB PC-150 SDRAM. All things (mobo, processor and memory) worked fine together(tried with my old PSU)  before building the computer into the chassis. Now when all other parts (DVD-ROM, HDD and PCI graphics card (yes, just trying with an old one ) have been installed, system refuses to boot, just blinking fast (5 times/sec) all d-leds + memory led + HDD and power led front panel lights. There's also strange knocking noise - in the exactly same tempo as lights are blinking (synchronized) New power is Nexus supersilent 350W. What could be a reason?
    I found a similar problem here in MSI forum, bu the question was unresolved.
    Please HELP!!!

    new case
    did you check all the stand offs
    sure you never left an extra one under the board ?

  • My Apple tv status light is blinking fast - how do I troubleshoot?

    my Apple TV gen 2 status light is blinking fast and I am not able to see anything from my Apple TV - how do I troubleshoot?  What I read on the Apple site is that my Apple TV has issues.  My Apple TV is hard wired to my Ethernet network.  It is connected to my TV using an HDMI cable.  It worked in the past but when I turned it on today it did not work.  I have not used it in several months and we had a bad thunderstorm here a couple weeks ago.

    I'm having the same problems as you. Any solutions? This is what i'm facing
    1. No video signal at all
    2. Plugged in power cable only, there is no light
    3. Plugged in micro usb, there is flashing light
    4. Restore via iTunes is sucessful but problem still persists

    My Apple TV is not responding. Screen in black and light indicator blinking fast. Cannot make it work. What should I do?

    Unplug it from power, wait 10-15 seconds and plug it back in.
    If it does not power up properly at that point, restore it via iTunes on the computer.

  • HT5706 my apple tv light is blinking fast and telling me to hook it up to itunes

    apple tv light is blinking fast and telling me to hook it up to itunes. is there any other way to fix this?

    No.
    You could take it to an Apple store for them to do it.
    See:
    http://support.apple.com/kb/HT4367
    Pay attention to differences in power connection depending on whether or not you have AppleTV2 or AppleTV 3.

  • HP F2480 - attention light and On are blinking fast. The printer works fine but scanner is dead.

    The On and Attention lights are blinking fast. The printer works fine but cannot connect to the scanner. I'm on Mac OS and when trying to open the scanner I get an: Failed to Open session on the device.

    Hi,
    These units indicate error messages by combination of blinking light. SO most likely has nothing to do withpanel cables and stuff. The pattern you are recieving indicates a scanner failure. Check HERE for a page with the differant blinking patterns and for possible solutions.

  • HT3180 tried factory reset as documented ... hold ... wait .... unplug ... replug .... light blinks 3 times then blinks fast

    tried factory reset as documented ... hold ... wait .... unplug ... replug .... light blinks 3 times then blinks fast ... what next?

    Welcome to the Apple Community.
    If your problem persists get yourself a micro USB cable (sold separately), you can restore your Apple TV from iTunes:
    Remove ALL cables from Apple TV. (if you don't you will not see Apple TV in the iTunes Source list)
    Connect the micro USB cable to the Apple TV and to your computer.
    Reconnect the power cable (only for Apple TV 3)
    Open iTunes.
    Select your Apple TV in the Devices list, and then click Restore.
    (You may already have a micro USB cable if you have a camera or other digital device)

  • Power Button and Attention button are blinking fast

    Power Button and Attention button are blinking fast simultaneously. I have tried turning it on and off many times, opened closed all doors, but the blinking seems to be returning everytime. It wouldnt even scan. In the Scan applicacation it says "Problem Scanning - Can't find the scanner. Make sure it's turned on and connected to your PC."
    I have recently taken it to Shraf DG from where I bought it. They told that they have replaced the printer assembly. However, the printer is not working and now the warranty also got elapsed.

  • Linksys SRW 2048 constant blinking and slow

    Hi all. I tried to search but was not very successful with finding my answer but my problem is that all of the ports are constantly blinking fast. Is this normal?
    I have the 2048 switch connected to a linksys wrvs440n router on port 48. Even the non connected ports are blinking dimmly. The internet appear slow as well. If I directly connect a PC to the router (bypass switch) the internet speed is greatly increased.
    I am not sure what to look for in the webview. Does anyone have any ideas that I can try?
    I even get this constant blinking if only one PC and the router is connected.
    THANKS

    THanks eepro. The ports that have a pc connected to are blinking constantly which I thought meant a collision was occuring. the other ports are only dimly lit and blinking but I think that just may be the other lights lighting them up from behind the front panel. The problem is even if there is only one pc connected there still seems to be constant blinking on that one port....
    The switch just came new from linksys on a warrantee return.
    Thanks

  • FP-1600 Status LED blinks 17 times.

    My FieldPoint bank has 9 modules. I previously had a problem with the FP-TB-10 power and ready lights blinking, but that was because one of my dual-channel modules was not seated correctly. Now the status LED is blinking 17 times. The manual says to contact NI about this. The FieldPoint Explorer seems to find all of the modules correctly, though. Anyone know what's up?

    Aaron,
    I checked the firmware and the FieldPoint Explorer version, and I'm using 3.20 and 3.0, respectively. When I power cycle the FP-1600, the 17 blinks of the status LED go away. Communication works, and all of the devices are found. However, communication does drop out from time to time, and eventually the status LED begins blinking 17 times again.
    A possibly related issue is that the FP-AI-V10 dual-channel module that I have plugged into slot 2 of the FP-TB-10 base causes the FP-TB-10 to flash its power and ready LEDs. Re-seating the FP-AI-V10 seems to fix this, although the module is definitely already clicked into place when I see this problem. Upon reseating (or just pressing on it without removing the module), the FieldPoint Explo
    rer program finds this module.
    I'm tempted to think that this issue with the FP-TB-10 and FP-AI-V10 are unrelated to the FP-1600's status LED blinking 17 times because even with the FP-TB-10 removed from the bank, I still get the flashing LED.
    Any ideas? Also, what is a GPF type error?
    Thanks,
    Jake
