Quad: Red Light when Turned On

Hello
Just powered up a Quad today. Brand New! When you press the power button, for about a second, a red light comes on (somewhere on the board) and of course very bright and visible through the Grill at the front and then goes off and everything is normal booting.
Just wondering is that normal? Can anyone confirm that all Quads (or DCs) boot up like this.
Thanks
Jas
Quad 2.5   Mac OS X (10.4.3)  

Quad owners, consider donating those many spare CPU cycles your not using (a lot!) to a good cause for a great team.
Will not interrupt your use of the computer. thanks

  • Xperia S does not turn on, red light when charging.

    My phone, after spending a day on a boat, was low on battery (this was 2 hours after leaving on the drive home). It went from 6% battery to shutting down completely in a matter of seconds. I plugged it into my car charger immediately, but it has not turned on since. Previously i have had problems with the headphone jack not recognising if earphones were plugged in or not, but this usually resolved within a few minutes. On top of this i have once struggled to turn the phone on due to i believe a once off problem with the power button.
    Recently the headphone jack has been playing up a lot more than usual, but it never resulted in this.  I have never experienced any other problem with the phone. PROBLEM: Once it turned off, I have been unable to restart my phone. When charging it shows a dull red light like when charging less than 15% battery. I have charged it now, on and off using multiple different charges for 6 hours, and have left it on its original charger as i write this. The power button plus volume up has no effect. There is no vibrations when i turn on the device. The screen which usually loads something when charging, has not displayed anything since turning off. It does not connect to either an apple or windows computer with a usb cable, volume down key depressed or not. It does not get hot to touch while charging, and i remember according to AVG that the battery quality that day was "good". After 6 hours of charging, the red light is still there(and usually a full charge after 1.3 hours, leaves a green light) Put simply, the only responce of any kind i get from the phone is a red light when charging. What have i done? recharged the phone for 6 hours, tried power button, restart button combo, usb connection with both an apple and windows computer, i also put it in rice in case there was any water but did not change anything. anything changed? after 2 hours of charging on the wall, the red light disapeared... tried the above, nothing happened, unplugged the phone then replugged it in... red light. I will try to get it repaired shortly along with a broken PS3, but i would rather a solution, as both my work and social life heavily depend on it. thankyou in advance

    If you have given it a good charge and still have no luck, I would advise running a software repair. This can be done with the phone powered off:
    1. Download the PC Companion software from http://www.sonymobile.com/gb/tools/pc-companion/
    and install it on your PC.
    2. Install and open PC Companion then select Support Zone.
    3. Phone Software Update.
    4. Start.
    5. Repair Phone
    6. Continue
    7. Accept data removal
    8. Next
    9. Wait for prepare
    10. Select Phone
    11. Follow the connection steps

  • Ipod shuffle 4th generation device not shown on itunes, not charging. Seeing red light when connecting to USB charger for a few seconds, then nothing. How to fix this?

    My ipod shuffle 4th generation was working fine for a few months. My son then bit the USB charger. I bought a new USB charger, but the shuffle is not charging and not showing up under the devices in itunes. It also doesn't appear in my windows under my computer. Just to note. I also have a new ipod touch. I am able to charge that fine on the same computer using the USB charger. The device (Ipod touch) does show up in windows and in itunes. The shuffle doesn't show in either place.
    I have tried to use the apple support page. I went through each step. I made all of my USB drives not shut down, I had my computer on all night to try and charge the shuffle. All I see is a red light that appears on the shuffle for a few seconds when I first connect the USB charger to the computer. Then, nothing. Since this was working a bit ago, I don't think that I have a defective shuffle. The USB charger is brand new, I just picked it up yesterday from the apple store. I have the short one, and the longer cable as well.
    Any help that you might be able to give to me would be much appreciated. My daughter is missing listening to her music. Thanks!

    Instead of "charger," you should call it the "USB cable" to avoid confusion.  When started reading your post, I was thinking, how can your son break a USB power adapter (the "charger" that plugs into a wall socket) by biting it...
    Since you got the product with the two USB cables at the Apple Store, you have the right replacement (some third-party replacements are for the 2nd gen shuffle and do not work with the 4th gen shuffle).  Make sure you are completely inserting the plug into the headphones jack.  The fit may be tighter than expected, since the connectors are new.
    http://support.apple.com/kb/TS3572
    If you tried both of those cables, it would be unlikely that you got two faulty cables in one package.  If a new USB device has been added to the computer between the time it worked with the old cable and now, there could be a problem on the USB bus (such as not enough power or a device conflict). 
    As a test, you should shut down (power off) the computer and disconnect all USB devices (including any hub), except for standard keyboard and mouse (if used).  Do this to reset the shuffle
    http://support.apple.com/kb/ht1655
    Start up computer, run iTunes, and connect the shuffle by itself to a direct USB port on the computer.

  • Red light when charging

    I am traveling internationally & remotely so can't take my wife's Macbook in or get phone support for awhile. We noticed recently that when we plug in the charger the light goes from its usual green to red in several seconds although it keeps on charging. Also, possibly related, the screen has started blinking off frequently (whether connected to charger or not). We need to keep using the computer but don't wish to hurt it either. Anyone have any thoughts. Thanks.

    Hi Robert,
    The light on the MagSafe connector turns green when it is fully charged and turns amber when it is charging the battery.

    By the screen blinking off do you mean the screen goes black, you push any button and it comes back on? Or the screen flickers and you can't do anything to make it come back on?

  • 6300 flashing blue lights when turned off!

    I've had a problem recently, I turn my phone off, and the blue lights flash quickly, and the phone is discharged by morning. I'm currently having to leave it on all the time and charge it.
    I've removed battery and sim and re-sat them.
    Any ideas?
    When I do turn it on again, it seems to freeze on the black screen saver for a while too.
    What error message are these flashes indicating?
    Thanks in advance...

    The notification lights are a red-herring, they normally flash when the phone is switched on/off.
    If your battery is not lasting, then you need to check that the battery itself is OK, and if so check this advice on maximising battery life:

  • My Macbook Pro speakers aren't working and the headphone jack is emitting a red light when I try to play something with sound. HELP!

    The question says it all. It worked perfectly last night and stopped working this morning. A whole day has gone by and the speakers still don't work. I've plugged in headphones and that works.
    When I try to increase volume or decrease volume, it shows me the mute sign which makes no sense at all. When I try to unmute, it stays muted.
    HELP I'M ON THE VERGE OF BREAKING THIS P.O.S. LAPTOP

    SO I just now had the same problem. A million threads online suggested to try inserting headphones, toothpicks, or even qtips to try and switch the "switch" inside the headphone jack. Everyone had great results from using the toothpick method. Well that didn't work for me. here's what FINALLY WORKED!!--> I wrapped a toothpick in fashion tape (fashion tape is basically stretchy double sided tape. If you don't have any ask some girls and someone will have). My thought was that maybe this "switch" didn't need to be flicked or pushed like a button. Maybe it was stuck in like a button that has been pushed in. I used the sticky toothpick to pull up the button/switch. Basically, take the toothpick and pressdown on the switch (supposedly the botton is inside the jack at the 6 or 7-0clock position) and then press the toothpick away (so that you are pushing in the opposite direction [1-oclock]). do this multiple times so you're flicking the toothpick back and forth. Just make sure you press firmly enough in the 6-oclock position so the tape can get stuck to the button.
    Two tips for this method:
    1) I had tried a manicure q-tip first, which in hindsight could've cleaned out the headphone jack, facilitating a surface that can get stuck to the fashion tape effectively.
    2) You can see in the photo attached that I wrapped the tape on the toothpick a little past the edge so that there was extra tape on the end of the toothpick. That was (and this is just my theory) to make up for the fact that toothpicks have a tapered end. I figured that having this extra loose bit of tape at the end would allow me to reacch into any nook or crany of the headphone jack where this mysterious "button" might be lurking.

  • Flashing red light, No turn on, solutions tried & failed - help!

    Ok guys, heres whats happened. I decided to update my BlackBerry 8120 yesterday to the latest 4.5 software, however I noticed that the update software seemed to be doing nothing, and after 40 minutes of being sat on the same part of the update, I disconnected the phone and decided to restart the update. However, the phone seems reluctant to connect, and when it does, the update just hangs at the same part again - the loading JVM section. 
    I have downloaded and attempted to use JL_Cmder, however that seems unable to either connect to my phone or unable to wipe it for some reason.
    I have also tried loading the loader with the command prompt of nojvm, however that doesnt work either.
     Can anyone point me in the right direction to getting my phone fixed? I purchased it second hand, and it was fine until me being the **bleep**, tried to update it.
    Cheers!

  • No red light...wont turn on

    Need help, no red light when plugged in, wont turn on!
    history:
    My Bold 9900 has been rebooting itself and not recognizing my memory card for about one month. Usually a quick reboot is all that is needed to restore the phone but not the memory card.
    Last night I plugged my phone into the wall to charge and this morning it was unresponsive. No red light, no yellow light, nothing. I tried plugging it in with another plug and let it charge for several hours but still no activity.
    I have tried:
    several times to do a quick reboot by removing the battery waiting and then replacing the battery.
    I have let it charge, removed the battery for 15 minutes then left it alone for 2 hours. 
    I am using a Mac so not sure where/how to do the system reboot. Yes i have Blackberry desktop software, but cannot follow the windows directions since i have a Mac.
    Suggestions please?

    Hi and Welcome to the Community!
    I think you may have already tried this first part, but I cannot be certain. Therefore, please try this sequence...note that, throughout the entire 4h15m process, your BB must remain directly connected to a known-good wall charger (not PC USB, not a cradle):
    With the battery inside, connect your BB to the wall charger
    Leave it alone for 2 hours, no matter what the LED or the display does
    Remove the battery
    Wait 15 minutes
    Insert the battery
    Wait another 2 hours, no matter what the LED or the display does
    This has been known to "kick start" some BBs.
    It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:
    Obtain an known good and already fully charged additional battery...use it in your BB and see what happens
    Obtain access to a known good and identical BB...use your battery in it and see what happens
    The results of this will indicate if it's your BB or your battery that has the problem. Note carefully please that "new" and "know good" are not necessarily the same things. While rare, a "new" battery certainly could be defective. Rather, the simplest (and least costly, btw) method to conduct this test is to find someone with an identical BB who has no issues...trade batteries and see what happens.
    Good luck and let us know!

  • About the status light(s) when turning on

    Hi everyone !
    This is my first message on the official Apple discussions and my iPod shuffle is my first Apple product
    I have a question : when you start your iPod shuffle, are the two status lights showing you the battery charge for a few seconds ?
    When I turn mine on, only the light next to the power switch gives me that information
    (but that's the only case, when I set the volume, change the track, or press play/pause, the two lights do work both)
    I wanted to ask you the question cause the e-manual says that I can check the battery on the status light (no "S")...
    ...but a few lines after, it says the status lights ("S"!) are useful to see if a button is being pressed or to check the battery charge
    Can you tell me if that is a problem from my iPod or just... normal ?
    Thank you very much

  • Red light problem

    I have a red light coming from my headphone jack. In the sound output, the only thing there shows optical digital output, though nothing is there. It started when I dropped the computer, and now the internal sound will not work. I tried to spin the toothpick around, and the red light would turn off for a few seconds, then it would flicker back on. This has happened about 5 or 6 times, so Im not sure if Im doing something wrong or if its a bigger problem.
    Thanks!

    Please make a Genius Appointment and take it in for service. The red light is related to the optical digital output.

  • How do you disable "digital optical output" so the red light in headphone jack goes off and I can use the internal speakers?

    HI,
    I have a red light in my headphone jack and I see "correct responses" listed as "when digital output is enabled speakers are disabled." That's all well and good but doens't really help. HOW do you disable the "digital output," get the red light to turn off and be able to hear through the speakers? What's the SOLUTION to the problem. Sorry, just a bit frustrated. Any help is greatly appreciated.
    Best,
    dpeast12

    Allegedly this can occur if there is a contaminant in the headphone jack that makes the computer believe there is an optical connection there, so it shuts off the internal speakers.
    Try inserting and removing a headphone plug repeatedly. This ought to dislodge the junk, and seems to have fixed the problem for others. Hope it helps!

  • Macbook Pro - No Sound from internal speakers + No red light

      Okay so I know this a very famous issue (I've seen over a hundred threads with people having the same problem) but the problem I'm having is something I haven't seen anywhere else. I recently tried  to fix my headphone jack on my Macbook pro early 2008 model when it DID have a red light emanating from it but when I finally managed to turn it off with a little wiggle from my paperclip the sound still didn't turn back on. In my system prefs my sound output still displays "Digital Out" and no other option for internal speakers. I know my speakers are fine because I can hear the startup chime. Also, I had a broken piece from my headphones stuck inside the jack a few years back and I retrieved it in....let's just say, not the most professional way to do it (I completely destroyed my headphone jack while attempting to retrieve the broken piece and now the hole is too wide for any headphones), though afterwards the internal speakers still worked for a while, it was just the headphone jack that was messed up. 
    Basically what I'm trying to say is: is there a way to enable my internal speakers without using any hardware methods? Because I tried the paperclip fix and the red light did turn off, but still no audio + sound prefs still shows 'digital out'. I really don't care much for the headphones jack anymore because I'll just override it with some USB headphones.
    Thanks in advance

    I agree Nick - it is a concern especially on such a basic function (sound) - Linc is right, the issue is microswitch, sounds like a bad design or a huge batch of sub quality switches, checking the forums this issue is common on MBP's.
    Judging by the date and lack of further activity I assume you managed to get yours fixed at the genius bar ?
    I finally fixed mine myself but posting reply for others who have same issue as this - however buyer beware folks, try this at your own risk !!!
    The fix won't be liked by Apple Support, the genius bar, or the repair shops but it worked for me after over 12 months of using headphones / external speakers - WHAT A PIA !
    Method -
    Held  Macbookpro on it's side with screen open and headphone/ audio  port facing toward ground.
    Took WD40 can with straw dispenser and placed straw inside audio port - sprayed 3 or 4 one second burst of WD40 into port.
    Held MBP that way for 30 seconds giving MBP a shake to drain WD40 out
    (I performed this whole excercise outside where the WD40 could drain out without an issue ;-)
    I then took an old set of headphones and re-inserted / removed them from the audio port approx 20 times in and out with music playing on the MBP -  intially when inserted music will only come from headphones then eventually MBP internal speakers start working !
    I've tried everything else including the cocktail stick and bent pin inserted inside the port to try and free micro switch - nothing worked it was stuck fast.
    As stated, can't endorse this for anybody else - you do so at your own risk - just stating this is what I did to get mine working again !

  • Macbook 2008 no audio from speakers - can't disable digital audio - red light in headphone jack

    Looking for help with this problem, that seems like a lot of people had in the past and still have, but I see that a couple of discussions on it here have been archived. Too bad, as the problem continues.
    I seem to be having the same problem with my late 2008 white 2.1Ghz Macbook.
    I had used earphones a few times with movies and iTunes, with no problems. Now I've just rebooted to find that I have no audio from internal speakers (the boot up chime works though). Earphones work perfectly.
    There is a constant red light in the earphone jack. The volume icon in the top menu bar is greyed out. In the Sound preference panel, Built-in Speakers are not available as an option for audio out. The only option is Digital Audio. If I connect earphones, then they are available as the only option.
    I have tried all the various methods that people have recommended, to switch off digital audio through the earphone jack: trying to flip the little switch with a toothpick, paper clip, etc., as well as cleaning around inside the jack with a bit of rubbing or cleaning alcohol; also tried inserting and removing the earphones plug several times, while pushing the volume buttons on the keyboard. Nothing works.
    I did get something from inserting/removing the earphone plug, as I seemed to be able to adjust volume from the keyboard, but I never got sound out from the speakers; the volume window seemed to indicate increase/decrease volume as I pressed the keys, but after a few seconds the volume window greyed out again with the No Entry symbol.
    Trying to flip the digital audio switch in the jack occasionally gets the red light to turn off for a couple seconds, but then it comes back on.
    Is there any particular problem with this that can't be solved by the aforementioned methods, that many people have used to solve it in a simple manner? Could my problem be more serious? Is there anything I could do if I opened up the Macbook, e.g., somehow to manually turn off the digital audio switch?
    Any help greatly appreciated.

    Got it fixed with a small flathead screwdriver with a fairly wide blade. Opened iTunes, started playing songs, had red light in headphone jack, as per usual with this problem.
    Put screwdriver in jack, with blade more or less vertical, started moving it around inside of jack in clockwise motion, pressing pretty firmly. Took just a couple of "swirls" around the inside of the jack and then audio finally turned on! Was a bit of a hassle, but finally worked.
    Many thanks to all for their suggestions.
    P.S. re. advice not to use metal object. This was the only way I was finally able to solve the problem (i.e., using the small screwdriver). I didn't see where using a metal object would be a problem, seeing as the headphone plug itself is metal. Anyway, it worked.
