  • Macbook switch off without any reason...

    hi there!
    maybe that question was asked before and then sorry for this but my bad english don't allow me to look easily for older topics.
    so here is the problem:
    my macbook (10.8.5) often switch off even if i'm 70% charged (or more) if i'm not plugged. Then i can't put it on if i don't plug the macbook before.
    i first thought that the battery was in bad ealth, but it's not (one and half year old, more than 75% of lifetime according to "coconut battery" software.)
    I secondly thought that the processor was overheating, but by checking it's temperature, i know its not.
    i heard that there was the same kind of problems on the 10.4.8 version generated by a kind of problem of transmission inside the computer (not sure exactly) and apple published a software whitch resolved that stuff. i got it but as it was for an older version, my macbook doesn't take it.
    Do you know if there is a newer version of that software?
    here is a link of the old one: http://support.apple.com/kb/TS1599?viewlocale=en_US
    maybe this is another problem, but i hope not and i wish you can help me.
    thanks for reading me (and i hope understanding me!)

    Two readings concern me:
    full charge capacity (mAh) : 3078
    cycle count : 465
    That is a very low full-charge capacity, and a very high cycle count. When batteries get older, and their cycle counts get higher, they can report incorrect information to the system about, for example, how much charge is left. Batteries can also become less stable and less able to handle fluctuations in power demands. Apple usually states that their batteries should offer good performance for 300 cycles, and you have gotten many more than that.
    I suspect you need a new battery.

  • Hi, I have a new laptop and would like to syncronise my iphone with iTunes (which I have installed again). But my old laptop has died so I could not transfer any media files, etc. Can I simply connect my iPhone to the laptop without any data being lost?

  • HT4623 Why the volume of iPhone keeps going down without any button being pushed

    The volume of my iPhone keeps going down without any button being pushed, why?

    Hello there Saber7,
    If I understand correctly, the phone seems to think the phones volume up is constantly being pressedbut the button still clicks when you press it. This should be easy to isolate to hardware or software, so I would start by quitting all the apps that are running on the phone:
    iOS: Force an app to close
    Double-click the Home button.
    Swipe left or right until you have located the app you wish to close.
    Swipe the app up to close it.
    When you have done that reset the device and test the issue again:
    iOS: Turning off and on (restarting) and resetting

  • Satellite C855-1CU switch on itself without any reason using Ubuntu

    Hi to all,
    I hope that somebody can help, I have a notebook TOSHIBA C855-1CU
    I installed Ubuntu 12.10 on a partition and WINDOWS 7 on another partition
    the question is : if I turn off my PC from Ubuntu then stays turned off for about 4-7 seconds, and then switch on by it self without any reason!
    Knowing that the same thing happens with my friends who have the same notebook .
    Thanks in advance.

    Hi there
    I recognize this. Had the same issue with Fedora recently.
    It is most likely a Kernel bug.
    You can try the following:
    - when running Ubuntu, remove the external power (unplug the AC adapter from the PC)
    - shut down the unit.
    Does it stay off now?
    If yes, I am most certain that this is a kernel bug and is already solved upstream.
    If You use Ubuntu 13.04 I believe this is sorted out.

  • Three or four times a day the radio module in my iphone doesn't responding. Sometimes it happened during a phone conversation, sometimes without any reason during a day.

    I have a problem. I use my iphone4 during one year. I bought it with firmware 4.0.2. Three or four times a day the radio module wasn't responding. Sometimes it happened during a phone conversation, sometimes without any reason during a day. Just I was out of connection for incoming calls. But it happened without any warnings on my iphone. After I have upgraded firmware to 4.1, this problem disappeared (baseband 2.10.04). But a week ago I upgraded firmware to 4.3.3 and my problem appeared again (4.10.01). I changed SIM-card, but it didn't help. How can solve this problem? I want to downgrade baseband to 2.10.04. Are there another solutions?

        Hi ZachBrunelle!
    I'm saddened that your having trouble with your device and you efforts are  greatly appreciated, let's get to the bottom of this! You mentioned your device not having any physical damage, has it been exposed to anytime of water/moisture?

  • I Lost All My Contact without any reason

    I have lost my contact without any reason. The contact list are blank suddenly. I havent plug my iphone4 to my computer. I have shut the phone and turn it on several time but the contacts are all disappear. I havent syn the iphone with the itunes. I dun know why all my contacts are disappear. How can I recover all my contact list? THX

    I say try and go settings/mail,contacts,calendar/import sim contacts and hope they come back..
    also you could try and restore your phone from the previous back up you done,  before you plug your phone in copy your previous back-up onto your desktop so you dont lose it, then try restore your phone from that.
    thats all i could suggest
    hope it helps

  • My brand new iMac reboots itself without any reason

    Hi guys,
    My brand new iMac (fully loaded late 2012, 27", i7, 3TB fusion drive) reboots itself suddenly without any reason several times per day. After some testing I think I may have found what causes the rebooting. When I plug (and push in) some usb-devices like external drive or iPhone into a usb-slot (3rd. slot from the side) my iMac reboots. Also when a usb device is plugged in the same 3rd. usb-slot the computer reboots occasionally. My question is: does rebooting problem look to you like a hardware or software issue?

    Could be either. Regardless, take the computer back. If you are within 14 days from purchase date you can request a replacement, no questions asked.

  • Hi All, I have the latest version of iTunes, however since upgrading I can no longer get iTunes to recognise that any devices (iPhone / iPad) are connected? Can anyone help please. Paul

    Try holding down CTRL as you launch iTunes to see if it will repair the drivers.
    Or try Cerbu's post here.
    Or see TS1538: iOS: Device not recognized in iTunes for Windows, in particular section 5, forcing a driver update.
    Please let us know which approach works for you...

  • Satellite L300-17L is putting itself on stand by all the time without any reason

    Hello Eldorado,
    i am sorry that this is not a question in connection to the topic, but i have L300 - 17L laptop and from time to time it is shutting down (more specifically putting it self on stand by) without any reason.
    It is not the cooler or anything else..
    The battery is full, and that is happening while i am writing or working on the laptop generally!
    The local service says that is nothing wrong with the laptop, i am so nervous, i cannot work , it is interrupting my work ..
    PLEASE HELP ME! thank you

    Hi
    So what happens exactly?
    Does the notebook shuts down or goes into standby mode?
    You said it happens from time to time this means that it would not be easy to replicated this issue and I think the technician was not able to replicate this is it right?
    What applications are running if this happens?
    Did you try to restore the notebook back to factory settings using the HDD recovery or Recovery disk? Do this!
    Check also if your BIOS is up to date!

  • Leopard asking for password without any reason ?

    Hi,
    Leopard asked me for user password without any reason. I wasn't installing any software.. just surfing the web.
    Furthermore my desktop wasn't working so I relaunched Finder.
    Is it kind of virus or is it normal ?
    thanks

    I've selected All Processes but there isn't installer... see the picture:

  • Why our game removed from sale without any reasons??

    Our game golden miner is forced to be removed from sale without any reasons.
    Does other developers has similiar problem? How do you solve it?
    Thank you.

    If colorme will please forgive me, I have a quick question for you, KT...
    I'm simply trying to compute the cube of an integer, which I thought would be an easy job in Obj-C. But when I code:
    NSLog(@"20^3=%d", 20^3);
    The result in the log is 23. What's with that? Someone said something about using pow. Hello?? Is this a math program or a Batman app? Someone else asked if I could hum four bars of it. I don't think anyone is taking the time to read my question, and I'd prefer a simple answer without all the tUde!! Do you see what's going on in this case?
