Anyone help, my laptop cuts in and out of charge

When on charge, my loptop cuts in and out of charging making the battery go down. I have only had laptop for one month. Is this a common falt?

SMC = system management controller.
Here's the long answer. The power adapter senses power problems both at the input and the output - I mentioned protection circuitry at the DC output end. When the power adapter senses an AC line voltage input problem (even if it's less than a cycle), the adapter may momentarily stop charging. I believe that's what is happening to you. There are many reasons that this could happen: loose AC wiring at a switch or outlet, loose ground wire, line in-rush over-voltage, even something as simple as someone cycling a flourescent lighting fixture can cause a problem. To resolve this, you can:
Try a different power adapter. Due to a internal component tolerance stack-up, an adapter may be hyper-sensitive to AC line noise. If a second power adapter does the same thing, you can:
Get an AC line conditioner. I'm guessing a $75-100 unit would do the trick. If that doesn't work, you can:
Use the ungrounded, two-prong "duckhead" for the power adapter.
Cheers!

Hello Mark Malecki,
Thanks for the question, and welcome to Apple Support Communities.
I understand you are having some issues with iTunes on your MacBook. You may want to isolate the issues further by testing to see if they persist in a new user account:

If you have your iPad connected to the charger it could be the new "Hey Siri" feature that allows you to use Siri without pressing the home button. Do you have a radio on or are people talking ? Go to settings> general> Siri> Allow"Hey Siri"> off.

Just used my FaceTime for the first time, and my audio kept cutting in and out.? Why is it doing that? Or what's causing it? HELP!

I tried facetiming for the first time and my audio kept cutting in and out.. WHY!? It was so annoying. Does anyone know what might be the problem? Connection? Thanks!

Do you have a Corp. Exchange account on your phone? I ask, because the requirement to encrypt an iPhone backup can be enforced by a profile installed on your phone when setting up the Exchange account.

4G and Data cutting in and out

I have had a Thunderbolt for about 3 mo now and about 4 days ago my phone stopped picking up 4G. I have used the phone info test and have it set correctly to pick up 4G. The data will also cut in and out if I am streaming video or playing games. I am more concerned about the 4G. It was running continuously from the day I bought the phone until 4 days ago. I have rebooted several times but will not go into 4G. Any help would be appreciated.

Please reply and let me know if you are still having problems getting connected to 4G.
When you rebooted, did you remove the battery & even the SIM card? Once you removed & reinserted, what happened?
Is there anyone else with or around you that may also have a 4G device from Verizon? If so, are they also having problems picking up 4G?
Have you also tried these steps from the phone?
(Two work arounds provided to us from HTC are listed below)
1. From the home screen, select Applications.
2. Select Settings.
3. Select Wireless & network.
4. Select Mobile networks.
5. Select Use packet data.
Enabled when a orange check mark is present.
The next is..,
1. From the home screen, select and hold the status bar (located at the top of the display).
2. Drag the window shade to the bottom of the display.
3. Select Mobile data.
Enabled when a orange indicator is present
Let me know what happens. I want to ensure you are able to continue to Rule The Air with your 4G device.

Sound cutting in and out on Macbook Pro 15 (original) when waking display

When I wake the display from sleep, any audio that was playing when the system went to sleep - or rather, the display went to sleep (ie: pandora, QT movie, etc), immediately starts to cut in and out and gets glitchy. This happens as soon as I move my mouse and get the dialogue box to enter my un/pw to wake from sleep. The only way to resolve it is to quit the application putting out the audio, and then open it up again. Once I do that, the problem goes away.
Currently running 10.6.2, but have had this problem since upgrading to Snow Leopard. I've searched the forums and can't seem to find any answers. There are a lot of vague sound issues with MBP and this is a hard one to "sum up" in the subject line. Any help would be appreciated. Thanks.

I've searched the forums and can't seem to find any answers.
Not even quitting out the audio application prior to letting your computer sleep?
Not sure what you have already tried from searching the forums. If you have Applecare, give them a call or take your computer to an Apple store. Let the Geniuses there check it out.

Does anyone know what would cause this all the suddenly? More importantly does anyone know how to fix this?

Logic Pro X Audio cutting in and out

When I am trying to record in Logic Pro X the audio seems to cut in and out at random points.
I have a MP3 track that I am recording to and it just randomly cuts out. Even when just playing that track by itself the same thing happens though never at the same spots. If I open the MP3 in Itunes or Quicktime there is no problem with the track.
As this seriously messes with the time of the piece and makes the recording long and painful I need help.
Is there some type of connection I am missing? I am using an old Presonus Firebox as an Interface, it unfortunately has adaptors to take it from firewire to thunderbolt. Recording into a 27" Imac that is very souped up and shouldn't have any problems until I hit a hundred tracks or so and I am only trying two.

It's most likely the Fusion drive, one of the symptoms is audio cutting out.
There are several related threads in this forum regarding audio problems with the Fusion drive.
This thread alone would take a couple of days to read.

A fix is supposed to be coming in the next operating system update.

Audio Is Randomly Cutting In And Out In Playback

I have encountered this problem on all recent Premiere projects I've worked on with a variety of audio types. My audio is cutting in and out in a seemlingly random way while the video keeps running fine. Sometimes the audio will play fine for 15 seconds then stop, sometimes it stops and starts after about 2 seconds. I have tried adjusting all of my preferences, settings, audio types, and even video types but the problem always comes back. Spoke to a friend who's new to Premiere and he's having the same problem. Considering moving back to FCP despite the weak interface.
Currently I am editing Canon 5d Mkii footage at 1080p, 29.97 fps. I am using none of the audio attached to the video clips - only editing to a separate m4a music track. My audio is at 44100 Hz. I am playing back video at 1/4 quality. I am running a fully updated Mac Powerbook with a 2.6GHz Intel Core i5 and 8gb of RAM.
Please help, almostly completely unable to edit. Thanks.

I am still having the same issue in Premiere CC 8.0.1 (21)
Exact same issue as the original poster on this thread, as well as the original poster on this other thread:
Premiere Pro CC Audio Cuts Out
So this audio issue persists from version 7 now in version 8.0.1!
For me, audio is cutting in and out randomly and never in the same place. If I have multiple audio tracks on the timeline, then one or more tracks might drop-out at the same time. Sometimes all tracks drop out at the same time. It seems completely random.
I am editing with a combination of P2 footage and DNxHD 290 footage. (I originally had some AVCHD footage, but then I transcoded all of it to DNxHD 290 -- but this did not improve the audio issue at all.)
Two of my audio tracks contain the native camera audio (stereo); 1 track has the music bed (stereo .wav files) and 1 track has sound effects (stereo .wav files)
In one of my projects, I had a very strong reverb effect applied to the track (not to the clip). When the audio dropped out, I could still hear the tail of the reverb. This leads me to conclude that it's not the entire audio track that is muting -- it's definitely the source audio clip that's dropping out. The reverb tail continued after the audio dropped out.
Playing the same part of the timeline again produces randomly different results -- audio might drop out on a different track, or at a different time, or not drop out at all.
This bug is making it nearly impossible to edit! I have filed a bug report at http://www.adobe.com/go/wish_fr
During timeline playback, my CPU utilization never goes above 15% and at least 12 GB of RAM is staying free, so I am pretty confident these drop-outs are NOT caused by lack of computer resources. Also, my hard drives seem to be fast enough to play back 4 streams of HD simultaneously, but I am getting these audio drop-outs when playing back 1 stream of HD plus 4 channels of audio. Therefore, I don't believe this can be a hard drive bandwidth issue.

Bluetooth speakers cutting in and out while typing

Anyone have any issues with there bluetooth connection to speakers for yoga 11s on windows 8.1?

It also Does NOT cut out like this on skype.

MacBook sound cuts in and out & getting a beach ball a lot.

When I try to play a video the sound either cuts in and out or just stays off. You can barely hear a small popping noise through the speakers. The chisel also lags very band making it impossible to watch, it does not matter if the video is online or on the computer itself. I also get the beach all allot even sometimes just using Word. Is there any way to fix this without wiping the hard drive?
Here is a video if this will help

Hi I have experienced this problem also, especially when listening to mp3's. At first I thought the quality of mp3 was the cause (as in different encoding quality) but it seemed to happen when playing DVD as well. I don't think a reboot will solve the problem for good, as it happens quite randomly. I have a sneaking suspicion that the internal speakers may be at fault. doesn't hurt to get apple to check it out while under warranty.

Keyboard cutting in and out...

hi, i have one of the brand new macbooks (santa rosa chip, 2.2 ghz.....) and my keyboard on it seems to be cutting in and out...i've only had it for a week, it's happened about 3 times or so, where the keyboard will all of a sudden stop responding, then a couple minutes later all of a sudden work again...any ideas...please help!

There's a very long thread on that problem here: http://discussions.apple.com/thread.jspa?threadID=1217703&tstart=0. It seems to be a fairly common problem, which Apple is apparently aware of. Mine did it once last week, but I reset PRAM (hold down P,R, option and Command keys as you start your computer, then wait for 2 chimes before releasing) and it hasn't happened since, thank goodness.

SUBTITLES CUT OFF AND OUT OF BOUNDING TEXT BOX

SUBTITLES CUT OFF AND OUT OF BOUNDING TEXT BOX
by Ben Martin on Jun 24, 2008 at 9:57:39 am
I use Encore version 2.0 and have problem with subtitles on a 30 minutes video. I have not imported these subtitles, but made them, one clip at the time. The first 10 minutes is fine, each subtitle is within a bounding box (the bounding box was stretched up to the first inner rectangle of the Safe Area). They can be seen fine on the timeline and on the DVD.
However from one particular subtitle onwards, all the subtitles clips seem to suffer from the same problem. When I play them on the timeline the long subtitles are cut off at the right end. When I click on them within the monitor, I see that they are not within a normal bounding box. Instead the text is sort of "embedded" within a structure of white squares (similar to a bounding box), but any attempt to strecth that "structure" by pulling a square with a text tool, only deform and extend the text itself.
I have tried to create a blank subtitle clip after the last "good" one, using the Add subtitle button on the monitor, but it won't create an empty bounding box within which I could type or paste the text. It works if I try to create an empty clip in the "good" area of the time line (the first 10 minutes), but not before or after that first bad clip I mentioned above. It is as if there was something bad on the timeline and any attempt to create a proper bounding box clip is impossible.
Is there a setting that I can change? or is it a bug in the programme?
Any help would be appreciated. Thanks.

Payday

In order to aviod stretching the existing text, you must use text tool to resize the boundry box.

Speakers cut in and out

I have a 03 pontiac sunfire. Ever since I bought this vehicle a year ago all of the speakers will cut in and out. The rear speakers will only work every now and then. None of the speakers sound like they are blown. Also the head unit will turn off if the parking brake is applied. Any ideas?

sounds like bad speakers, factory amplifier, or bad installation. get your car into your local geek squad to have it fixed and working the way it should be working. $20 per 1/4 hour or $80 per hour is the normal troubleshooting for a vehicle. thanks for posting and good luck!

Surround sound receiver is causing Apple TV to cut in and out.

My Apple TV is cutting in and out and I think my Marantz surround sound receiver is causing it because when I hook Apple TV directly to the TV it works fine. I looked at my receivers owner's manual but did not find anything helpful. Any idea how to resolve it?

Welcome to the Apple Community.
Check that the wifi channel is set to the same channel as on your previous router, also check the multicast rate is identical.
If the problem persists, you might also want to see if netgear have a forum or a help number and ask there.
