Macbook problems after using usb power

Hi, something verycstrange happened to my macbook yesterday, i bought some speakers with usb energy conection, when put in usb macbook turned off and now i cant turn it on. No way, when conect charger , not even the light turns on, absolutley nothing happens anymore. I brought the notebook into the apple store but it takes a few days. Anyone of u have an idea what that can be. I m a bit surprised that this happens to a mac, its not even 2 years old

Welcome to Apple Support Communities
Your MacBook does not turn on and even the power adapter light does not work, so it looks like the whole logic board is damaged somehow. If this is the problem, it's going to be a expensive repair for sure (unless you have AppleCare). This is not the first case I see related to Macs stopping working after connecting a USB peripheral.

Why is there no data on my new MacBook Pro after using Migration Assistant?

Last night I launched Migration Assistent between my MacBook to my MacBook Pro. It said it would take 12 hours so I left it over night. When it finished this morning it said that some files were not able to be transferred. But there is absolutely nothing on my new MacBook Pro. Why is that?
My TimeMachine backup disk has a cable that won't work with the new MacBook Pro so what other choice do I have to transfer data?

XE connection problem after using Cisco AnyConnect Client

Hello
I have a rather annoying problem connecting to an XE instance AFTER I have disconnected from a VPN via a Cisco AnyConnect VPN Agent.
Sequence of operations:
- start Oracle XE and work normally
- connect to client's vpn
- do other stuff
- DISCONNECT from Client's VPN
-> unable to connect to XE service any more, unless I reboot
The problem does not happen with other vpn clients like Cisco VPN Service, Juniper, Checkpoint.
Details:
- sqlplus connection WITH service name (eg sqlplus user/pwd@XE): FAILURE with ORA-12170
- but...sqlplus connection WITHOUT service name (eg sqlplus user/pwd): SUCCESS (weird !)
- tnsping XE: TNS-12535 error
- lsnrctl status output (sorry, italian localized)

Using USB Power Adator in S. Korea

Traveling to S. Korea and wondering if I can go ahead and plug in my iPhone using the usb power adaptor that came with my iPhone. Of course, I will get a plug adaptor for their odd looking plug ins. I think I remember plugging in my MacBook Pro and iPod no problem last time.
Any good tips on what features to shut off so ATT doesn't charge me thousands of dollars during my 3 week stay?
Thanks in advance.

There is no problem using the adapter in South Korea. It is dual voltage, so it will automatically work for you.
Have a good trip and enjoy your iphone...

Problems after using LIST_TO_ASCI

Hi Experts ,
i am facing an uphill task after using the Function Module LIST_TO_ASCI.
CALL FUNCTION 'LIST_TO_ASCI'

LIST_INDEX_INVALID       = 2
OTHERS                   = 3
I use this function as above .
Now the values in the ascitab are in string format
i used submit report for FS10N transaction .
Now after submit
then LIST_FROM_MEMORY'
then LIST_TO_ASCII
i get the value in string
now my problem is that it displays exactly how *fs10n* dispalys the whole output
i want only the last field value .
that is the cumlative balance value that is practially speaking the last field in the FS10N report .
How can i achieve that using this ASCITAB table obtained from LIST_TO_ASCI

MacBook problems after sleep mode

I am constantly getting the beach ball after my laptop comes out of sleep mode. It doesn't happen immediately, usually 5-10 minutes after I open it and begin using it all applications will freeze. I can force quit them, but I cannot re-open the application, or anything else on the computer. I am forced to shut down using the power button because I cannot even shut down normally. This happened shortly after I downloaded Lion OS.. Is there a way to fix this or am I screwed?

Hi Z,
Did you create a backup right before installing Lion?
If so, I'd go back to it.
If not, I'd reinstall Lion.

Software 2.0 : no audio after using USB accessory

I've discovered what I believe is a rather interesting (and rather serious) bug in the iPhone 2.0 software:
When an USB IAP accessory (such as a lot of newer car stereos) is connected and disconnected a couple of times the audio output from the iPhone will often stop working. Disconnecting the accessory or plugging/unplugging headphones does not fix the problem.
And I mean the audio completely dies: I get no audio from the phone, voicemail, ringtones, iPod, or system sounds from the speaker, headphones, or dock output.
It's like the audio drivers crash. Sometimes the audio will start working again after a long period of time (like if the phone has been sitting idle for hours while I'm at work) but usually I have to reboot to get it working. It seems when I can get audio to work again without a reboot, I get a new crashReporter log about mediaserverd the next time I sync.
The problem occurs when the phone is connected to an iPod accessory that uses the IAP audio-over-USB capability (I tried my Pioneer car stereo and a Kenwood stereo at Best Buy) It does not occur when connected to an accessory that only uses analog audio. I've seen it happen on my iPhone 3G and the original iPhone, so I know it's not a hardware problem.
I know for a fact the Pioneer and Kenwood units I tested are stated as having USB inputs compatible with the iPod Video, iPod Nano, iPod Classic, and iPod touch. (I can confirm the Pioneer does work fine with my old iPod Video.)
Multiple reviews have shown them to also work well with original iPhones running 1.1.4 and below (even if you do get the "not made for iPhone" warning)
However, both phones I tested are running 2.0. Which leads me to think this is a bad 2.0 bug?

"It's by design..."
Nope; not referring to "airplane" mode issues here. This does seem to be a compatibility issue with USB devices, regardless and independent of the response to "use Airplane mode?" dialog.
Experiencing this, good to know others are too, bad to know it's still an issue (and misunderstood too?).
Steps to reproduce:
1. Connect iPhone3G to a USB-compatible audio device (Kenwood car stereo here, front USB input, model KDC-MP438U).
2. Car stereo functions correctly, lets me browse and playback songs for up to 2 minutes
3. Playback ends abruptly; car stereo reports a "USB Error".
4. Remove iPhone from connector (after pressing and holding "USB Remove" button on car stereo).
5. Audio playback thru iPhone has ceased. Voicemail, apps/games, etc... no audio.
6. Reconnecting the iPhone (without a full reset) appears to resume playback (track timer indicator resumes), but no actual audio.
6. iPhone reset returns functionality.
Side note: my iPhone is charging correctly during the 2 minutes of functioning playback. I'll check again if it's continue to charge after audio ends.
Also checking Kenwood forums, but the fact you (TWParker) have experienced the issue across stereo brands, and only after 2.0 update, seems to point finger to Apple.

Having bluetooth connection problem after using Yosemite for a week

After installing and using Yosemite for a week, I experienced bluetooth connection problems with my magic mouse and headphone, my model is macbook pro retina early 2013, hope to fix this soon

Hello there Oranger84,
If I understand correctly you are having some sort of Bluetooth issue between your computer and Magic Mouse and Headphones after installing Yosemite. Depending on the particular symptoms you are seeing, I would recommend the following article to help you get that resolved:

Thank you for using Apple Support Communities.

Problems after connecting USB 1.1 devices to an unpowered USB hub

After connecting a mouse, usb stick and an external hardrive to an unpowered USB 2.0 hub, I now get no response from any of those devices, though they had been working fine before. Other devices that I have since plugged into that same usb slot work just fine. What could possibly have happened??? I appreciate any insight!

Nance,
Welcome to the Discussions.
You did not mention if each one of these devices still works when plugged directly into the USB 1.1 port. If they do, then I cannot explain the problem. If they do not, it is possible the USB 1.1 port was overloaded with all three devices connected to the unpowered USB 2.0 hub. You may have gotten such a warning on the screen.
If you have not done so, I would disconnect all devices, shut down the powerbook, then reset the PRAM.
http://docs.info.apple.com/article.html?artnum=2238
Now test each device by connecting directly to the USB 1.1 port.
If both the USB stick and USB HD (I am assuming that you have an unpowered 2.5" HD) were mounted on the computer's desktop when this 'possible' power shortfall occurred, it could have corrupted both devices so they will not longer mount properly. Connect each device to the USB 1.1 port, then see if Disk Utility can see the device and repair any damage. The mouse may no longer work if the preferences or other software was corrupted.
If you are running an unpowered HD, I would recommend a powered USB 2.0 hub so you can connect other devices without worry.

My Macbook freezes after using it for awhile

I startup my MacBook (aluminum 2008 verions) running lion 10.7.1 and after about 5 minutes of using it, my computer displays the rainbow cursor and freezes. I am unable to click on anything or force quit.
My processor is 2.4 Ghz and has 2Gb ram.
It would be great if someone could give me any thoughts ASAP as I have an assignment due next week and need my computer.
Thanks in advance

Your problem is caused by third-party software that you installed. I'd need more information to be more specific.
Reboot as usual (not in safe mode) if you haven't already done so. Launch the Terminal application, copy or drag -- do not type -- the line of text below into the window, and press return:
kextstat -kl | awk ' !/apple/ { print $6 $7 } '
Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.)
Next, do the same thing with this line:
sudo launchctl list | sed 1d | awk ' !/0x|apple|com\.vix|edu\.|org\./ { print $3 } '
That's one line, not two. You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.
Next, this command:
launchctl list | sed 1d | awk ' !/0x|apple|edu\.|org\./ { print $3 } '
Again, one line. Finally, one more:
ls -1 /Library/{InputManagers,StartupItems}
Remember, this is all drag-and-drop or copy-and-paste, whichever you prefer -- no typing, except your password.
You can then quit Terminal.

Can't see iTunes files after using usb drive for time machine

I have a usb 1TB drive with my iTunes files on it from my old MacBook, I now have a MacBook Pro OSx 10.9.4 and I set it to be used for TimeMachine. I no longer can see my folders/files. Why and how do I get access to them again? I know they are there just can't get to them.

Never mind found out that files were never there.
