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?

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.

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

Start up computer, run iTunes, and connect the shuffle by itself to a direct USB port on the computer.

IBook G4 with red light on charger

Hello,
I have this problem of starting up my iBook G4. It doesn't turn on at all when I press the power button.
At first, I thought it was low on battery. So, I charged it and the red light is on no matter how long I charged it. May I know what does the red light represents?
Does anyone encounter this problem?
Thanks in advance, guys.
Regards
Yee

Welcome to Apple Discussions!
I don't know if this will even be relevant to your situation, but there is an article which talks about the red light with regard to powerbooks:
http://docs.info.apple.com/article.html?artnum=18241
One question would be whether this battery and charger worked properly in the past, or if one of them has been replaced. The article made it sound like some batteries and chargers do not work together, and if you replaced one or the other, there might be some incompatibility.
Hopefully someone who really knows about this will post back. I don't have any personal experience with this--I just remember reading about it in this article.
Good luck!

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 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

No light when charging

Hi, I have a 1st generation ipod shuffle. the battery light is red so I obviously need to charge it. The problem is that when I plug it into my laptop's USB port, nothing happens. Itunes doesn't come up (I don't know if it's supposed to or not), but more importantly, there's no flashing amber lights to tell me it's charging. What's the problem?
Thanks, Janie.

Hi, Janie
Is this the first time you're trying to connect it to that specific USB socket? The Shuffle requires a powered USB socket in order to charge. Some older machines with early USB functionality don't have this. You might need to use another USB socket, either on your laptop or on another machine altogether.
If this is the case, I believe that it's possible to connect the Shuffle to a USB hub (one that would require an additional power supply and to be connected, in turn, to your laptop) to charge. Finally, I'm pretty sure you can purchase a charging dock for the Shuffle from Apple shops.
Powered USB or non-powered, the iPod should appear in your iTunes, but I'm guessing it may not if the battery is too low.
Hope I've helped somehow.

Mag Safe Power Adapter - Red light on charger

Hello,
I have had my MacBook for about a week now. I love it! However, when I plug the charger into the wall, and the other end into my computer, the end where I plug it into my computer (with the little LED light on it), is showing orange/red on the LED light. It is green for a few seconds when I plug it in, and it was green since I've used the MacBook, but now it is red/orange. I am just wondering if this is a big problem I should be worrying about, or if everything is okay. The charging status on toolbar shows the lightning (charging) symbol, and I am watching my battery percentage go up, I am just concerned obviously. I love my MacBook, and want to make sure there is nothing wrong with it. Please get back to me with any info ASAP. Thanks.
John Kasprzak

That is perfectly normal.
The green light indicator on the magsafe adaptor indicates that the power is going to the computer, and not the battery (i.e: when no battery is installed, or when the battery is fully charged).
The amber light indicates that the power is going to the battery as well, meaning that the computer is being powered by the adaptor while the battery charges at the same time. The amber light also shows when the Macbook is off and the battery is charging.
So, in summary:
Amber=battery charging.
Green=battery not charging.

Blinking Orange Charger Light when Charging L855-S5405

I have a Toshiba Satellite Laptop L855-S5405 that I bought in Oct 2013 and I replaced the battery around a week ago since it does not stay charged for last very long and the PC Health Monitor said that the battery health was poor. I also replaced the AC Adapter since it would only work if it was held a certain way. When I charge my laptop now, the charging light sometimes blinks in a pattern of 7-8 times then stops but it happens at random, it's not like it blinks 7-8 times then stops then starts blinking again immediately. When the blinking occurs, my laptop stops charging but begins charging again after it stops. I have my laptop on and working when it is charging and it does not really affect anything as far as I can tell but I would still like to know what this pattern means so I can fix it.I have tried uninstalling the Microsoft ACPI-Compliant Control Method Battery then reinstalling it like I have seen in other forums but that does not work and turning off my laptop and unplugging the AC Adapter and taking out the battery then holding power button for 30 seconds then putting everything back in does not work as well. I cannot seem to find anything similar to the problem I have whenever I look online or at the forum from what I have seen so any help would be appreciated.

Is none of these suggestions work, it likely requires servicing unfortunately:

Red light on charger?

Hi,
On my new macbook, the screen just dimmed slightly and the charging light switched from orange to red.
What does that mean exactly?
Should I unplug it?
Thanks
apt

Hi,
That usually means that it is charging the battery on your Macbook. I think that's normal. The screen dimming is also normal, it does that before it turns the screen off/engages the screensaver. I don't think that the two are directly related though.
I hope this helps...

Solid Orange Light When Charging, Yet Ipod Broken?

So, at some point in the past I walked into the ocean with my IPod shuffle. Yes, stupid move, I know. Anyway, it still worked for a little while afterward, and I got a new IPod, which got stolen. So, recently I've been trying to get this IPod Shuffle 2nd Gen to work. I've tried browsing topics to no avail so decided to post.
Here's the symptoms:
1. IPod cannot be recognized by either my computer(Windows XP) OR ITunes.
2. My IPod will not light up at all unless plugged into my computer, in which case it turns orange as if charging.
3. I've tried the 5 fixes. None of them worked, and the IPod will not play music.(Though I'm not sure it still HAS music.)
Any ideas?

On a 1G Shuffle the fix was to disassemble, rinse with distilled water and CRC, carefully dry, re-assemble, and hope for the best. I'm sure the same would be true for the 2G, but I've never taken that one apart; I'm sure the same folks provide the guidance on how to do that, however.
OTOH, a brand-new one is $49 ...... and it even comes with printed warnings against walking it into the ocean.

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.
