Airpoprt Won't wake up

In reading threads on this forum I see a very common issue with connecting through airport and such after updating software.
For me, my issue is that airport does not reconnect to my computer to computer network after coming out of sleep mode. I have tried it in automatic, in preferred and also deleted and reselected the network, no luck. If I add my router to the list of preferred networks it does find and connect to it.
The way I see it I can try 2 more items. I can delete the network and build a new one on the iMac (this is an existing network that was working fine before the update) or I can get up at 3am and download the huge update instead of the smaller one I used before ( the file size is over my 24 hr bandwidth limit & 3am -6am is free time)
If anyone has any other ideas I can try I would be most grateful. Oh, I have also did the permission thing, but not sure I understand what I am doing there.
thanks in advance for any help.

Disabling the processor sleep feature IS a perfectly fine solution. I have been doing it that way on all of my Macs for many years without any issues.

  • I'm using a late 2006 2.33GHz imac.I clean installed 10.6 from disc then updated to 10.7 from download.Now every time my computer goes into sleep it won't wake up.Anyone know how to cure this problem please??

    I'm using a late 2006 2.33GHz imac.
    I clean installed 10.6 from disc then updated to 10.7 from download.
    Now every time my computer goes into sleep it won't wake up.
    The only way it will restart is to pull the mains lead out of the imac, put it back and try until it will start.
    This only happened after reinstalling.  Only Apple OS was on the imac and so it must be an issue with the software I believe.....
    Anyone know how to cure this problem please?
    Thanks

    This isn't a fix, more a workaround I used when I had wake from sleep problems that lasted from some point in 10.6.x, through 10.7 and into 10.8 (got fixed for me in 10.8.2). It seems to be connected with Bluetooth failing to wake up properly:
    System Preferences>Energy Saver and set 'computer sleep' to 'never'.

  • Mac Mini/Mountain Lion sleeps but won't wake up (or crashes) every night.

    Hi everybody,
    I have a mid-2010 mac mini server on which I recently installed Mountain Lion 10.8.2 (without server stuff).
    Every night, it stops responding. The led is on but the display is off and it does not respond to mouse/keyboard. I even tried remote desktop.
    The only solution is the power button...
    What I already did :
    - Reset Pram/Nvram
    - Reset SMC
    I also took a look at the console and I found a message that is fired just before the machine stops responding.

    Any clue ?

    Hi, I'm quite interested by your issue, because i get the exact same one.
    On my mini (late 2012), system doesn t wake up from sleep if it has slept for more than 1 hour.
    In fact I get the exact same message as you get in your console.
    When I try and wake up system before the programmed maintenance wakeup, it wakes up fine.
    But as soon as this programmed time has passed, it just won t wake up, I have to force switch it off via the power button and restart it.
    I have nothing plugged on my mini except : AC - Thunderbolt display, and LAN connected to my freebox.
    Do you still have the issue or is it ok now for you ?
    I'll try in the upcoming days to plug the freebox in the thunderbolt display's adapter instead of the macmini's rj45.

  • Won't Wake From Sleep

    I held off from posting this until I'd scoured the boards looking for ideas, but I'm totally out.
    Every since I updated to 10.4.8, my MacBook Pro won't wake from sleep. I've tried resetting the SMU and PRAM, enabled and disabled bluetooth device wake from sleep, and installed the latest EFI Firmware update that was just released. I've now narrowed it down to the 10.4.8 and a change in how it handles Expresscards. If I have my NitroAV FW 800 card plugged in during a session, it seems to prevent the MacBook from going to sleep properly. According to various Console messages, the PCI device prevents the computer from going to sleep, and /or places the computer into System Doze instead, from which it won't wake. The sleep light stays fixed and steady, only disappearing if I press the power button (it only reacts to the power button). From there the screen remains dark and all plugged in device fail to respond. I can hear the drive spin back up.
    It reacts the same whether or not I eject the card before putting the computer to sleep. This behavior was not present before installing 10.4.8 and having fallen back on a back up of my 10.4.7 install, can say it's not present in the older OS version. I was hoping last night's EFI firmware update would deal with this, but after having installed it and 10.4.8 anew, I'm having the same old results.
    If anyone has any new ideas or can direct me toward how I can make sure the folks at Apple see this, I'd greatly appreciate it.
    MacBook Pro 2.16 Ghz Core Duo Mac OS X (10.4.8) 2 GB Ram, 7200 rpm HD, NitroAV ExpressCard FW 800

  • Macbook pro retina display won't wake on windows 8.1

    Hi,
    I have installed windows 8.1 on my new Macbook Pro with retina with using bootcamp no problem there only issue is after my laptop goes to sleep it won’t wake up. It seems that the issue is with the display driver or something related to it because even when only display is off I have the same problem.

    I am aware there are symbols. My technical issue is the MagSafe2 adapter. What people typically do is connect their laptops to the wall when they're battery dies off. No biggie. I can attach it to the outlet. Well, when I connect the adapter to the outlet, nothing happens. Nothing happens at home, at Starbucks, at McDonalds, at other people's home.
    When I brought this up with technical support in August when I bought it, technical support person said I might have issues with my electrical wiring at home. I've never had issues with electrical wiring at home because my other Apple products work fine when connected to the outlet. My July 2011 MacBook Pro charged without a hitch.
    And I was able to charge my Retina MBP only at night or very early in the morning.
    But this weekend, I couldn't charge it at all. I'm starting to think it might be the MagSafe2 adapter problem.
    I feel rather ridiculous buying the highest-end of the 15 inch Retina MBP. It cost me over $3000. Right now I'm working with my 5 year old Hewlett Packard laptop. At least my HP works, which can't be said about this top-of-the line Apple product.
    Probably explains why Apple stocks are falling. At $3000 I shouldn't be having these type of problems.
    Sheeeesh!!!

  • Memory RAM upgrade won't wake up after sleep mode

    i just recently purchase a pair  16GB RAM of crucial  CT2K8G3S160BM for newegg.com. Yeesterday i try put this on my macbook i7 intel 2.9 processor that crucial said is compatible. but found out everything was good until i close my mac lid for hibernate. What happen is, it won't wake up no matter what i do until a way of reset SMC. BTW i try stick by stick to plug in together with my original 4gb RAM together found out 1 was ok and other one was not. But somehow why the info of hardware show that memory ram 16GB was installed and was OK. Everything was run smooth even booting. The only problem is won't wake up after sleep mode. I already try reset smc, pram, delete startimage, delete powermanagement.file and also sudo hibernate 0-7. Did anyone had this same issue of me. I'm my curiousity will it be the bad ram or software problem.

    i just google around and found this two both crucial ram. Both spec are the same but different model no.
      CT102464BF160B 16GB  and mine is CT2K8G3S160BM are this 2 same? but both same spec.

  • Display blank, key board light not working, won't wake up if sleeps.

    Hi. I just bought a Toshiba Satellite P850 and after two weeks I had the first big problem.
    It starts normally first time but after a shut-down and a few hours later start,the display is blank, any light on.The back light keyboard the same - only the power button and battery/wireless-connection have the light on.
    If I shut it down again and then restart (by pressing the power button) nothing happened same screen and no light.
    Tried to do this.. remove battery,press pow. button for 30-60 sec,plug charger,and the restart. it works. but after a shut-down and a few hours later restart,I have the same problem. If sleep mode it won't wake up.
    Don't know what to do.. it's a brand new Toshiba Satellite. used a few hours a day for two weeks.

    It sounds like the computer is going into Sleep mode or Hibernation and not coming out of it. Go to the Control Panel and select Power Options. Whatever your current power setting, select the Advanced settings under it. Check out your Sleep and Hibernation settings. In this case, I would disable them. You might want to enable the Screen Saver and let that kick in if you're away from the computer for any length of time.
    In cases of mysterious computer issues, the best policy is to simplify. Reduce the number of attached devices. Keep the number of open applications down to a minimum. See if you can figure which hardware or software is causing this problem. And you should be able to fix it.

  • Display won't wake up

    It's a brand new notebook.I've done nothing on it, other than installing Windows updates and creating recovery disks.I set the "Turn off display after" option to 1Minute.IMPORTANT: I set display brightness all the way to zero, the lowest setting possible, using either the keyboard keys, or the brightness option in Windows.Leave the notebook idle for a minute, the display sleeps like it should (the notebook is set to sleep after 30 minutes, it's only the display that sleeps, the notebook is still awake).Move the mouse, press keys on the keyboard, the screen does not come back up. The computer is still up and running-i can toggle keyboard backlight On/Off using the keys, but the display won't wake up.Press the "Brightness +" button on the keyboard, the display wakes up. This is the only way to wake it up. The other option is to press and hold the power button, force a shut down, and start the computer again.This happens ONLY when "brightess" is set to the lowest level. If brightness is set to even one level above the lowest, the issue cannot be reproduced. Moving the mouse or pressing any key on the keyboard will wake the display up in this situation.Both Intel HD graphics 5500 and GTX 850M drivers are up to date.BIOS is up to date as well.Battery/ Plugged in does not make a difference. If the display brightness is set to lowest, the screen will ALWAYS fail to wake up, irrespective of which power source is in use. What do I do? Please don't tell me it's a minor problem and I have to live with it.There are so many minor problems with this notebook, and all these are adding up to make it a total piece of cr.. My almost 5 years old probook with a second generation core i3 CPU and no discrete GPU, is better than this brand new 5th generation core i7+GeForce GTX notebook. I'm beginning to regret this purchase. I should have gotten another probook. Thought the Envy offers a better "bang for the buck", and now i think this was a huge mistake. Anyway, any idea how i can get this fixed? Looks like a driver problem right? Or is this a hardware problem? Can someone with an Envy notebook try this out and tell me if the issue can be reproduced on their rig? It can't be reproduced on my Probook.Thanks.

    Thanks for your reply Avenger Well, I called up HP tech support.The lady took remote control of my notebook and tried numerous things in the registry (regedit).But the issue could not be solved. She then arranged for an on-site support engineer to visit my house.The Engineer showed up right on the next day, and tried the following:- Updated ALL drivers, even the ones which were already up to date!Checked with my desktop monitor, the issue cannot be reproduced on the external monitor- the external monitor will wake up on moving the mouse, but the notebook monitor stayed dim (no backlight).Opened the laptop, took out the display cable, cleaned it with some solution he had, put everything back together- issue not resolved, external monitor wakes up but notebook monitor stayes dimmed. This is not the only problem I was having with the notebook, the other problems are:Battery would stop charging when the notebook is switched OFF, and the charger is turned ON and OFF a couple of times.The battery lock doesn't "click" in place, it slides automatically to the "unlock" position, it's loose.There's a dead pixel on the display. He offered me two choices: 1> Replace motherboard (to solve battery not charging issue), replace chassis (to solve the battery lock issue), and replace display panel (to solve the dim display + dead pixel issue). =======OR======= 2> Return the whole notebook back to HP, and get a new notebook (same model) in exchange.  I picked option 2. We shared a cup of coffee, and the tech left (he was very nice and friendly). The next day, I got an email from HP, with a PDF attachment, asking me to take my laptop, along with a hard copy of the email, and payment invoice, to the HP store. HP store took my computer back, but they didn't have a replacement ready, they asked me to come after 7 days to pick up a new notebook (same model). I really loved my Envy. It's a very nice looking laptop. Hope the replacement I get won't have these weird issues. I'll update the thread when I get the replacement. Thanks for your help   

  • MacMini (late 2012) ML 10.8.3 won't wake up

    Hello,
    My MacMini running ML 10.8.3 will go into sleep after some period of inactivity, and won't wake up (typically happens overnight, but not only). I have to shut down using the power button and turn on again.

  • A600 Won't Wake Up - Help!?

    I have an ideacentre a600 that I upgraded to Windows 7 Ultimate.  Randomly, the computer will just go into sleep/hibernate mode and it won't wake up.  I've tried all the usual methods to wake it up, like moving the mouse or hitting keys on the keyboard and nothing is working.  I even got creative and tried plugging in a wired mouse to see if the USB ports were asleep to no avail.  The only way I can tell the computer is still running is that the touch sensitive controls on the front panel will light up when touched but they don't wake the computer up.  I've adjusted all the settings in the computer including the display and power settings and there is nothing there to indicate it should ever go to sleep.  It probably happens about once out of every 5 times but it is extremely frustrating because the only way to get it working is to do a hard shutdown on the PC by holding the power button down and then booting back up.  Please let me know if anyone else has encountered this or what can be done to fix it.
    Thanks,
    J

    lenovo a600 again with win 7 and i have the same problem ! the keyboard and the mouse won't wake up ....help somehow....

  • HT5219 I have a macbook air (mid 2012) and a thunderbolt display. Do I absolutely need to connect the power supply together with the thunderbolt cable ? I found that the screen won't wake up if only the thunderbolt connection is plugged.

    I have a macbook air (mid 2012) and a thunderbolt display (27''). 
    Do I absolutely need to connect the power supply together with the thunderbolt cable ?
    I found that the screen won't wake up if only the thunderbolt connection is plugged. Is this normal ?

    I just got my ATD and late 2011 MBP up and running. I've not tried running without the power adapter from the ATD plugged in, but I just tried and didn't have any problems with the display not waking. You may want to take your query to the ATD forum - https://discussions.apple.com/community/peripherals/thunderbolt_display - perhaps someone there has experienced a similar issue.
    Good luck,
    Clinton

    Hi David,
    - Have you tried any troubleshooting steps?
    You may try the following steps:
    1. Reset SMC as per the following article http://support.apple.com/kb/HT3964?viewlocale=en_US. If this does not resolve the issue then go to step 2.
    2. Navigate to Macintosh HD/Library/Preferences/System Configuration and remove a file called powermanagement.plist (drag it to trash, might prompt for a password). Restart the mac thereafter. If this does not resolve the issue, boot to safe mode as per http://support.apple.com/kb/ht1455 and check the issue there. If it works there, you will have to remove the following files to check Macintosh HD/Library/StartupItems, HD/Library/Caches and then restart the mac.
    Let me know if this works.

  • 10.9.2 sleep issue won't wake up.

    When 10.9.2 on my iMac 27 mid 2011 goes to sleep naturally overnite it won't wake. I have to do a reboot with the back button. Is anyone else having this issue?

    Hello JInterisano
    For issues with waking from sleep, check out the article below to troubleshoot the issue as well as using the additional steps at the bottom.

  • Rev B Won't Wake Up

    I have a Rev B 17" iMac that I have never had any issues with until today. It would not wake up from sleep and when I pressed a key the screen was black and the fans went full blast. I then powered it down and restarted and everything was fine. Ran hardware test which it passed. Any thoughts as to the reason?

    If it happens again, try the following;
    If your Mac happily goes to sleep but won't wake up--Hold down the power switch to force-reboot your machine and get it running again.
    Don't worry-your Mac isn't narcoleptic. Its Open Firmware system or NVRAM (nonvolatile RAM) is likely corrupt, and your Mac can't remember how to wake up.
    Restart your Mac and immediately hold down the Command-Option-O-F key combo until you see a somewhat intimidating command-line display that ends with the Open Fimware prompt. Type the following lines:
    reset-nvram
    press Return on keyboard
    set-defaults
    press Return
    reset-all
    press Return
    Your Mac will reboot. Once it's running, put it back to sleep to test. If the problem recurs your Energy Saver preferences may be the culprit. Delete the com.apple.PowerManagement.plist file (go to Finder/Hard drive/Library/Preferences/SystemConfiguration)--don't worry, your Mac will regenerate a new one--and then restart to see if that rights the wrong.
    Still did'nt work? Might be time to call AppleCare or see an Apple Genius or a technician.
    Cheers!

  • Nec monitors won't wake up

    I have two NEC PA272W Spectraview monitors connected to a 2013 6 core, MacPro with dual 500 video cards and 64 gigs of memory.  I have tried all the monitor settings to put them to sleep and wake them up.  They will go to sleep in several of the auto off settings but won't wake up.  If I leave them on all the time the computer will blank the screen, but it still glows indicating it is drawing a lot of power.
    Is there anything I can do to get them to sleep/wake like all the other monitors I have had?
    thanks,
    Mike

    I got a reply from NEC Display support.  This is a known problem with their monitors and Mavericks.  They made the following suggestion which seems to be working:
    "Dear Michael,
    The Off mode should be set to Standard. I have spoken with a level 2
    technician, who gave me some trouble shooting that you may want to try.
    1. Disconnect the signal to the monitor, either by turning off the computer or
    disconnecting your connection cable.
    2. The "NO SIGNAL" message will appear on the screen. Press the RESET and EXIT
    buttons simultaneously 9 times when you see this message.
    3. You will then have the option to change the DP PLL PMS POWER setting to ON.
    4. Also, please ensure that the power save timer in the advanced menu is shut
    off.
    Please let us know if this works for you.
    Thank you,
