Don't understand blinking lights in my shuffle
My iPod Shuffle displays an alternating blinking lights, yellow and green. i searched the Apple support and I discovered that the blinking lights indicates an "error", but doesn't mention what to do... Can anyone help me on this..
Hi,
If you ipod is blinking "yellow" rather orange and green, you may want to restore your ipod. Follow this link http://docs.info.apple.com/article.html?artnum=60983. Good luck

I'm trying to check the status of my battery. My shuffle is on, I'm pressing the voice over button twice, but I don't get any light at all. What should I do?

Shuffle stops playing occasionally, 5 green blinking lights
hi,
my 4th generation ipod shuffle occasionally stops playing a song, seemingly caused by a minor movement of the shuffle or the headphones. when this happens, the indicator light blinks green exactly 5 times. the behavior is otherwise like clicking pause (which blinks green 30 times) in that clicking play again fixes the problem. it happens pretty commonly when running, though some days it never behaves this way and other days it shuts off almost constantly. putting the shuffle into lock mode doesn't help. it also seems unrelated to the battery level.
it's behaved this way for some time though i'm past my coverage period. anyone else encountered this and/or know a fix? i've already got the latest iTunes and shuffle software installed.
thanks.
-mikeI tried the cotton swab approach from http://techtips.salon.com/ipod-pause-itself-3299.html. I took a Q-Tip, ripped off most of the cotton, dipped the Q-Tip in rubbing alcohol, and cleaned out the ipod shaft and the headphone jack. You could tell it was lubricated when I put in the headphone jack, as it swiveled pretty easily. After doing this, I had no playback problems. Where before a slight movement of the headphone jack would stop playback, now I was unable to stop playback short of removing the headphone jack completely.
I also was pleased to discover that the 5 green blinking lights are exactly what happens if during playback you remove the headphone jack completely. So that's consistent with some type of connectivity problem between the ipod and headphones.
Sadly, later that day, after leaving the headphones connected to the ipod for a few hours (turned off), I found I was back in my initial state where a slight movement of the headphones turns off playback. I really thought I had found the permanent solution, but it seems like I might be routinely using rubbing alcohol and a cotton swab to make the ipod work normally.

Stop the sleep blinking light in lenovo g-470, whining sound from the power adapter , HEEEEEELP !!!
Hi, hope anyone can help me.
I own a lenovo b560 and a g470, the sleep light will blink when I go to sleeping mode, anyway the problem is not the light, the problem is the whining sound it produces the power adapter when the light start blinking, in both machines I hear that whining noise, but in the g470 is much louder, I don´t know if this is because I have a faulty adapter or something, the strange thing is that both adapters make the noise when I sleep the laptop, when I turn off or hibernate the whining sound disappear.
Also, I notice that the whining sound alternate in 2 types of sounds, one is high in pitch and the other lower, the high pitch is when the blinking light turn on when go to sleep and the lower pitch of the sound is when the light go off, and that is repeating until I resume the laptop, it´s very annoying, especially when I´m in a quiet room.
So my theory is that maybe somehow I can turn off the blinking light when the laptop goes to sleep and then maybe the whining sound will go away, but I don´t know, it´s only an a idea.
Any help will be appreciated.
Thanks !
Solved!
Go to Solution.I can really understand your pain with this issue.
Kindly update the BIOS and display driver from the lenovo website then check if the issue persist.
The issue should be resolved after this.

Why is this an error??? I don't understand why it is... Help Please
Hi,
Ok, I'll preface this by saying there's a lotta code pasted in here but it really quite an easy question, I just need to post all the code so you understand where what came from.
Now.............the question I'm trying to do is to create an applet that has 2 buttons -- each button when clicked opens an application (one is a simple calculator, the other a Mortgage calculation app). When you click one of the buttons (calc or mortgage), that app opens infront of the 2 button menu so its in "focus". The button on the 2 button menu then switches to a "hide app X" button (ie: "Mortgage", changes to "Hide Mortgage"). Thus if you click the hide button, the app that was opened is hidden, and then that "hide" button switches back to the original "app X" button. Pretty simple.
Now, I have from my text book an example that does exactly this, with the simple calculator already in it, and with another app (a traffic light thing) where the Mortgage should be in my final product. I also already have the Mortgage applet I need to insert from another book example in place of that Traffic Light portion.
Now, common sense would dictate that I should be able to just copy my code for the Mortgage applet into the example that has the 2 button menu structure, and overwrite the code I want to get rid of (the traffic light) with the mortgage code & rename the menu buttons. Right?? A simple switch of one thing for another... but therein lies my problem.
I copied all the Mortgage code in correctly over the traffic lights, switched the button names, tried to compile it but I get one error....
Exercise12_17.java:52: cannot resolve symbol
symbol : method pack ()
location: class MortgageApplet
mortgageAppletFrame.pack();I don't understand why..... mortgageAppletFrame.pack(); was a simple rewrite from lightsFrame.pack(); like every other line...... it should work. I've gone over it for 2 days......... Anyone know why it comes up as an error???
Below, in order going down is (1)my code with the 1 error I can't solve, (2)the original menu example I tried to edit, and (3)the Mortgage app code...........
Does anyone know what my error is?? Help or a hint would be greatly appreciated........ Thanks.

If you want the same behaviour as in the code with traffic lights, change
class MortgageApplet extends JApplet implements ActionListener {
to
class MortgageApplet extends JFrame implements ActionListener {
and change
public void init() {

Blinking lights office jet pro 8600
HP has been very cooperative in clearing my problem. I am on my 3rd office jet pro 8600 plus, N911g. After a short period the blinking lights appear "turn printer off, then on" no other message. It's OK for a brief period and then the lights reappear. I have done everything HP support says....I have also moved the printer from room to room thinking that might help....still the same problem. Any suggestions, or must I just accept the lights. I am using Windows 7. Also an HP Laptop. Love HP and the printer.
Welcome to the forums Migee,
I saw your post about your Officejet 8600 showing blinking lights and the message to turn the printer off. I would like to share my suggestion that might help!
Update the printers firmware: Getting the Latest Firmware and Product Updates
Plug the printer in directly to the wall outlet, avoiding power bars and surge protectors. This ensures the printer is receiving full power and may help this situation.
Let me know if that helps. If not, please let me know if the printer is still in warranty with HP and we will go from there.
Have a great Monday

I'm 51 years old and recently retired. I have a new IPad Air. Which MacBook should I buy to go with it? I don't understand flash storage. It feels like I would have a bunch of flash drives to keep up with. Help an old lady out!!!
Depends on how you want to use it. Flash storage on the newer macbook and macbook air are built in. A macbook air is the most light weight and a very good machine. It will do all you want it to do unless you are running some very intensive programs. If you go to the apple store on line you can compare the different macbook pro" and macbook Air's.

HT202157 my apple tv device is flashing or has a blinking light??
my apple tv device is flashing or has a blinking light..... what do I do??
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:
1. Remove ALL cables from Apple TV. (if you don't you will not see Apple TV in the iTunes Source list)
2. Connect the micro USB cable to the Apple TV and to your computer.
3. Reconnect the power cable (only for Apple TV 3)
4. Open iTunes.
5. 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) -
Fast blinking light! What does it mean?
The other day I shut down my computer. (Intel iMac matte screen, 10.4.11) Later, when I pushed the restart button, I failed to get a bong & the sleep light started blinking rapidly & bright. For a number of times I held down the restart button to get it to shut down, & then pressed it again to restart...same blinking light. (I've never seen this behavior before) I managed to finally get it to restart by double clicking on the restart button, but I don't even know why I tried that.
Anyone know what's up?

That sounds like a ram problem!

Perhaps one of your modules has dislodged and need to be reseated, or is failing.
1. Try reinstalling-reseating both modules, firmly pushing on each one with both thumbs then close the ejector clips.
2. Then if it still acts funny, try installing one module at a time.

I hate the new KitKat upgrade. I hate the messaging white background. I hate the loss of the green blinking light in the left upper corner. I do not know why music plays whenever I get an email. I get hundreds of emails to my device and it plays music and is driving me crazy. How do I disable this? I went through all my settings and cannot find where this may be set. It's a bust if you ask me for the Android system. Booooo
An update should only improve your device performance mistygirl1209. I'm sorry to hear you don't like the aesthetics of the new OS. Although we work closely with manufacturers and OS developers, we don't produce the devices, operating systems or updates. I want to help you fix the email issue. What make and model device is this? What type of music are you referring to? What type of emails are these? Are there attachments in them?
