Scree goes blak for a while

When I plug in for charging battery then screen goes black for a moment?when i unplug it then same issue....please guide me how this matter solve it

Hi @mazhar321 ,
Thank you for your inquiry.
It is normal for the display to darken or change when you connect or disconnect the AC charger as it is changing power source from AC to DC and the system must recalibrate for the change.
If it actually goes black check your connections to see if it is loose or have a damaged pin.

  • Problem: I click, the spinning wheel goes on for a while and finally I get the result for what I clicked for! All the time ...

    I click, the spinning wheel goes on and on, and finally it clicks in! Does it everytime time ...Could it be MacKeeper fault? I have 90GB available on my mid 2009 13inch MacBookPro with 8GB memory. I am Mac OS X Lion. This is disconcerting. Thanks for any help.

    First, Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk. You could have some directory corruption. Let us know what errors Disk Repair reports and if DU was able to repair them. This could just be a start in repairs and you may need a better utility to finish the job.
    Then Repair Permissions.
    No need to report any Permissions errors........we all get them.

  • Buller? Anybody? The system extension "/System/Library/Extensions/ZD1211Mac.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update. This has been going on for a while.

    Anyone find a fix for this? Most programs installed invoke this error.
    The system extension “/System/Library/Extensions/ZD1211Mac.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.

    That driver appears to be for a Zydas wireless usb adapter. Zydas has been through a couple of different acquisitions and no updates appear to be available, so you'll probably need to delete that extension.

  • Ok, this has been going on for a while. Whenever I try to record my voice or any noises with the built in microphone, it plays back super quietly, even when I like yell or put it close to my mouth. Do I need a new iPod? Or is there something I can do?

    Help please!

    - Make sure the mic hole is clear and unobstructed. It is the little hole on the back by the camera lens
    - Open the Voice Memos app and see if you see movement on the VU meter needle with changes in noise level trying to be recorded.
    Try:
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Reset all settings      
    Go to Settings > General > Reset and tap Reset All Settings.
    All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
    - Restore from backup. See:                                 
    iOS: How to back up                             
    - Restore to factory settings/new iOS device.
    If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

  • Is there a new virus that affects Firefox? My browser is fine for a while and then the text will disappear, also some of the control buttons.

    This has been going on at least 3 months with the browser. The back arrow will disappear, sometimes the text completely disappears, sometimes you can see it but its unreadable, looks like the letters are missing pixels. Sometimes the images get corrupted with black pixelation. If you quit and restart it goes away, for a while.
    The problem seems to be affecting my online games as well. I play "Steampunk Tower" on Yahoo!'s free game tab and it always crashes my machine hard, as in abruptly shuts down the system with no warning. This is not the only game to be affected.
    I have both McAfee and Norton 360 and they find nothing when I scan, but they can only detect what they know about so I'm looking for something new and unreported. Or maybe an update failed or has corrupted a file, I don't know. I do know that its very irritating and I'd like to fix it, if possible.

    hello, maybe that's an issue with hardware acceleration - please try [[Upgrade your graphics drivers to use hardware acceleration and WebGL|updating your graphics driver]], or in case this doesn't solve the issue or there is no new version available at the moment, disable hardware acceleration in ''firefox > options > advanced > general''.

  • Mackbook can't drag and drop after working in indesign CC for a while.

    This has been going on for a while.  I am working in Indesign then all of the sudden all my drag and drop cappabilities are gone.  i have to restart my computer to fix the problem and being that the start up times for the cc software is outragous,  this sucks for my workflow.  I have seen Adobe techs say that there isn't a difference in the backend between 6 and cc for the whole suite but seeing is believing and I don't make things up.

    hi Dustin, maybe with a bit more info someone will be able to help with this:
    what Mac OS System version are you using?
    what is it you are 'dragging and dropping'? : Is this drag and drop of text in InDesign? Or are you dragging and dropping from the Mac OS (e.g. a file from a folder) into InDesign?
    If you are referring to drag and drop from OS into InDesign: I'm thinking this 'might' be a Mac OSX issue. If you look over at https://discussions.apple.com/index.jspa there seem to be plenty of issues with drag and drop across different OS versions.
    Next time it stops working whilst you are in InDesign, does it still work in other programs? That is one way of determining if this is caused by InDesign or the operating system. If it is the OS, my guess is that it stops working in other applicaitons as well.
    Hope this helps,

    The warranty for the iPhone is not and has never been International.
    Warranty and support are ONLY valid in the country of origin.  The only exception is the EU where the entire EU is treated as one country.
    If the device will be used in India, buy it in India.
    An unlocked iPhone will work on any supported GSM carrier world wide.  The LTE portion of a US purchased, unlocked iPhone is unlikely to work outside North America as it does not support the appropriate bands used in other countries.

  • HT3964 My MacBook Pro i5 Dual Core has a hardtime waking up when the computer is put to sleep and only when it goes to sleep and has been asleep for a while. The indicator light flashes on and off for a while and then freezes. I've done an SMC reset once.

    Does any one have the same problem with their MacBook Pro i5 Intel Dual Core?  If the computer goes to sleep (not the screen) and is asleep for a while, when I try to wake it up it doesn't respond. I have to power it downn and restart it and sometimes it takes two or three attempts. Otherwise it works fine. I upgraded the memory to 8 GB. That is the only alteration doen to it. I've performed one SMC restart and now it wakes up  but it takes a while and a gray screen shows up. When I insert a DVD it won't start automatically I have to start the application in order to see it. Any suggestions?

  • I am backing up my computer to an external hard drive using Time Machine.  It has been at 288.91 "used" for a while... should I just let it ride?  It's been going for about 7 hours now.

    It does not immediately delete the files that are missing.. it merely tries to backup the new files it has discovered on the external drive. Since you moved the files there, the backup at least for a while will contain both copies.. and that is why it doesn't have enough space to backup.
    Fixing the problem.. hmm pondini is the expert.. you should be able to delete the backup of the photos in existing backup.. there are instructions to do it.. but it is a very poor way to do things.
    Much better. .archive off the existing backup.. this is long and slow but worth it. you need a usb drive of the same size as the TC drive. Then erase the TC and start a fresh set of backups.
    The alternative is to use the USB drive as a new target.. but it is much slower than the TC internal drive.

    You are not addressing Apple here. If you have a problem, describe it and someone might be able to help. Just to be sure, the wi-fi on the phone will go off after the phone goes into sleep mode unless it is actively being used. This is a battery saving measure. If you are actively using the internet, and the phone is still awake, then the wi-fi should remain connected.
    What troubleshooting steps have you tried.

    Hello, what OSX version?
    Could be many things, we should start with this...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
    If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
    If 10.7.0 or later...
    Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
    If that doesn't help Reinstall the OS.

    im using an iphone 4s with the latest firmware which is 6.1.3 but my wifi button keeps going grey how can i fix it? i rested network connections and it worked for a while and went grey again,what can i do?

    Have you worked through the Troubleshooting iOS and WiFi knowledge base article?  If not, see if there is info in there that might help.
    Is the WiFi greyed out on all WiFi networks or just the one?  If it does this on all then there may be a hardwaer problem that needs attention from the techs at an Apple store genius bar.
    Before that, however, try a reboot by holding both the power and home buttons until the apple logo appears and it restarts, ignoring the red slider if it appears.  That clears a lot of iOS hang ups that occur.
