can anyone help, my late 2010 MBA's - OS X Lion 10.7.5 wifi won't turn on after a deep sleep.. thanks..!

Hi John,
Thanks for the additional information.  What I would try next is resetting System Management Controller:
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer. 
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
You can find the full article here:

If this still doesn't help, it would be time to take it in to be looked at.  You can setup an appointment at a Genius Bar by clicking on the following link:

    If you can't find it in your applications folder you will need to reinstall your Mac OS X. Take a look at this link, https://discussions.apple.com/message/16478873#16478873

  • Hi there can anyone help as i am unable to contact Apple for support with my printer which will not print after recent software update? this is the email i tried to send to apple with no success, can anyone help please.......Dear Apple, I'm pulling my hai

    Hi there,
    Can anyone out there help, after a recent Apple software update my Epson Stylus Photo RX640 will no longer print, every other aspect of the printer works fine including the scanner but it just will not print, I sent an email to apple but all i got was an automated reply directing me to their support page, the email i sent is below this explains in full what the problem is & what i have done to try & fix this problem.
    Dear Apple,
    I'm pulling my hair out after a recent software update from apple, since this update my Epson Stylus Photo RX640 will not print, every other function of the printer including the scanner works fine,
    Please see attached file of the error message coming up in the print queue.
    I have spent days trying to fix this, i have been onto Epsons website & followed their resolution for this error message to no avail, after contacting them again with the results i got an email back saying : In response to your email, the RX640 will use an inbox or gutenprint driver on Mac OS X 10.6.8, it is not compatible with an Epson driver.
    I have also tried re-installing drivers from original Discs for the printer but it still will not print, obviously this error has been caused by Apple's latest software update, when are Apple going to fix this problem? i need my printer working ASAP.
    Regards
    Brian
    PS i obviously can't attach the error message so here it is:    Error:/Library/Printer/Epson/inkjetprinter 2/filter/rastertoescpll.app/contents/mac os/rastertoescpll/failed
    Thank You all in advance
    Regards
    Brian

    It is hardly Apple's fault that Epson can't/won't update their driver, but at least Epson suggest that you use the Gutenprint driver, which in any case is far better that what Epson offer.
    You can get it here:
    http://gimp-print.sourceforge.net/
    You can download the latest version from here:
    http://sourceforge.net/projects/gimp-print/
    Have you downloaded the recent Apple update to Epson drivers?

  • Hello. can anyone help. I am not sure if there is a fault with my Time Capsule.

    Sorry about the long heading. Wasn't sure how this system works.
    Yes, I have had recent problems with Time capsule and backing up. It does not connect to the internet now for some reason.
    Today I pulled the ethernet cable and power cable out of the back of the Capsule and reconnected, and now there is no light at all on the time capsule.
    In trying to resolve the problem of not connection (and hence no back-up) a couple of weeks ago, I seem to have created a couple more network names in the list of available networks which I would like to delete - does anyone know how I delete these?
    I have read about reformatting the Time Capsule, but I am not sure if this will solve the problem. But Airport Utilities just shows that the internet is searching for a back up disk but is unable to find Time Capsule.
    Any help would be much appreciated. I am a bit 'thick' with these things so please keep any information / instructions basic and easy.
    Thanks a lot,
    Barjir

    Did you empty out all the names stored in your wireless setup.. if not then they remain??
    Here is my list.. Click the - button underneath and remove every single name.
    So you have no preferred networks.
    Reboot the computer and start again.
    Unfortunately it can be difficult to get rid of names you created for your own wireless, as those go into one of the lists.
    Find your listing of wireless names.
    /Users/YourName/Library/Application Support/Apple/AirPort/
    Delete all the plists there.. That helped me get rid of the ghosts in the airport utility. It should also get rid of the ones showing in your wifi.
    As far as fixing the TC which seems to be the far more important issue... you did not give me one key piece of info.
    My Time Capsule 3TB model is A1409.
    Does the light turn on?? According to your first post it is now dark.
    now there is no light at all on the time capsule
    The main LED and the ethernet LED must turn on .. they must blink when you power up and flash amber and then if everything is good turn green.. No lights on then nobody is home and the TC is dead. It is typical of the failure of the Gen4 TC.
    See https://sites.google.com/site/lapastenague/a-deconstruction-of-routers-and-modem s/apple-time-capsule-repair/gen4-a1409-issues
    The fix which one user has reported that worked was to reflow solder in an oven. A rather difficult and troublesome fix but one which reveals they had a bad batch. If that is what is happening to yours try to get apple to replace it by the methods I have suggested.

  • Hello, can anyone help? Safari errors, install RegCure clean system.

    Hello, I have never come across anything like this before. Does this mean I have a problem like a bug ? Who is RegCure? Should I install it? What will it do if it cleans system? I copied and pasted most of what the error says. Any advice?
    Safari has detected errors.
    We recommend that you clean your system immediately to prevent a system crash and/or loss of data.
    Install RegCure (Microsoft® Certified Partner) and clean system
    Technical Information:
    Could not initialize: HKEYCLASSESROOT\CLSID\{H2BKL0-7548-11CF-A520-
    Could not initialize: HKEYSYSCORE\VAR\{WL43320-7677-
    Corrupt entry: HD_SYSTEM\ID\{HF49480-7JF77-
    Thank you

    Two thumbs up for what Klaus1 said.
    *"Install RegCure (Microsoft® Certified Partner) and clean system"*
    They want you to purchase software you don't need, especially in this case, the software is for Windows only.
    Just ignore it.
    BTW, from the Safari Menu Bar, click Safari then click Block Pop Up Windows. That might help avoid that.

  • Can anyone help with my 2010 mbp running slow i.e. games are very laggy and slow to open apps

    i have a 2010 mbp and i cant run games that i was able to run flawlessly a couple months ago im not sure if iv done somethin to cause this issue i really only use my comp to watch movies and videos nothin that i would think would slow it the way it has if someone could give me some advise as to how to get it running 100% again it would be much appreciated

    Use this as a trouble shooting guide:
    https://discussions.apple.com/docs/DOC-3521
    Check the status of your HDD.  Open DisK Utility>First Aid and run Verify and Repair.  Also is the HDD full?  Often that is a problem.
    Try a Safe Boot:

    Often third party applications have a negative affect on performance.  Performance or cleaning apps as well as anti-virus apps are often the culprit and should be deleted.
    Ciao.
    You might also open Activity Monitor and examine if additional RAM might be useful.

  • Hello can anyone help me with iphone 4s problems

    hi all, got my iphone 4s a few weeks ago, few things im having probs with,one being when connected to my wifi in my house it decides to dissconnect it every few seconds on its own( my 3g never used to do this), and another prob is when downloading any app from the app store, the app box comes up on the screen but the progess bar does not move to show its downloading and the box stays grey no matter how long i wait, but if i then turn the phone off then back on again, the app is installed ? cheers

    Sounds like you are getting interference from something locally. Talk to O2 to see if anything can be done.

    The vi's contain some items specific to LV 6.1. They no longer run, but here you go anyway. You might be able to get them back working in 6.02 with some effort, or at least see what's being done.
    Good luck

    hello can anyone help to obtain VPN.

    Office for Mac 2004 is NOT compatible with Lion. It must be upgraded to Office for Mac 2008 or 2011, once you have upgraded the files will be accessable. Office for Mac 2004 is written for old PPC (Power PC) based machines. Beginning with Lion support for PPC based apps has been dropped.

  • HT1751 Hello, can you help? I have backed up iTune library to an external hard drive, but want to set up periodic back ups every month. Do I have to follow the "Consolidate file" procedure every time I back up, and does my original back become over writte

    Hello can anyone help? I have sucessfully backed up  my iTuines library to an external hard drive, but when backing up in the furture (Monthly)  do I have to follow the same procedure again, and will this place an additonal copy of my iTunes library on my hard drive, so duplicating the back up and so rapidly fill my hard drive.
    Ideally what I would like, is for the lateset back up to over write the original so saving space on my external hard drive. Many thanks ......Steve

    The "consolidate" command has nothing to do with making backups. You use that command when you have had content in multiple places and you wish to have it now all in a single iTunes folder. If all of your content is already in the iTunes folder, then the "consolidate" command will be of no use to you. You will make further backups using whatever method you normally would use to make backups of your data in Windows.
