Dark screen remains after waking from sleep mode

Whilst using Safari Version 3.1.2, Mac OS 10.4.11 on my Powerbook G4 (aluminum, 1.5 ghz), my screen remains dark upon waking from sleep mode. Trying to increase screen brightness is ineffectual for some reason likely related to this problem. My only workaround is to force shutdown and restart. Any ideas about a solution would be greatly appreciated.

Hi Gary,
This behavior is not a Safari issue but system related.
Close all applications an run in utilities> disc repair permissions.
After you done reboot an see what happens when your Mac gets to sleep mode again. This time don't open any applications to test it. Just leave it showing your desktop.

  • Screen Black after waking from sleep mode (after 10.4.11 update)

    This issue has happened before with an earlier update (10.3.8 Delta fixed the issue originally), and I suspect it is the same with this current update.
    Has anyone else had this problem with the new update and has there been a patch released to fix the problem yet? Hopefully we can get an update soon.

    This happens every so often to my 12" Aluminium PowerBook after sleeping (black screen, hard drive spinning away) and after trying every possible key combination and nothing helping, I'm usually left with the usual last resort, which is a hard restart. Of course that remedies the problem short term but unfortunately, only until the next time it happens. For me, it has been an issue since I bought it and is not affected by the OS.
    I am wondering if it has anything to do with the clasp not working properly when the lid is closed. Sometimes I get the sleeping light, sometimes not - unless I play with the lid until it clicks shut. Then the light appears. Importantly, when the sleeping light appears, the machine always wakes properly with the lid opening. But I have noticed that when the light does not come on and I haven't bothered to shut it down properly, that is when the problem occurs. Which makes me wonder if rather than going into sleep mode it is actually going into hibernation mode due to non use? I haven't a clue but perhaps someone here knows far more about such things than myself?

  • Black screen after waking from sleep mode - Compaq Presario CQ5110F

    My mother's computer has been having the problem listed in the subject -- after waking from sleep mode, the monitor just stays black, and won't come back. After trying everything I could find online, I eventually found the bios update which claims to fix the exact issue. The problem is that I guess my mother had opted to upgrade to Windows 7, while the bios update seems to only work for Windows Vista, as I get the following error message: "Your system does not meet the minimum requirements for this update. Update has been canceleld. (9998)." I've tried running the update in Vista compatibility mode, with no luck. I've tried using a different monitor, I've updated all the drivers, Windows Updates are all current, I've cleared CMOS. Any idea on how to fix this? It's very recent; only for about the past 2 weeks has this been happening, while we've had the computer for over 3 years. It's quite a waste of energy to keep it on all day.

    Hello liltwix,
    When taking your computer out of safe mode the screen just remains black, is that correct? I will try to help you with this issue.
    I understand you upgraded from Vista to 7, was that when the issue started or has the computer had windows 7 installed for some time before this problem started?
    Please respond back at your earliest convenience.
    Thanks

  • My MacBook Pro won't reconnect to my Wi-FI automatically after waking from sleep mode

    Hello, everyone. Since I updated to Yosemite, my MacBook Pro won't reconnect to my Wi-FI automatically after waking from sleep mode.
    Does anyone know how to fix that?
    Thanks in advance,
    Arthur.

    Hi, arthurpacifico. 
    Thank you for visiting Apple Support Communities.
    Here are a couple troubleshooting steps that I would recommend trying to see if it corrects this issue.

    http://support.apple.com/kb/HT3964
    Reset your computer’s PRAM
    http://support.apple.com/kb/HT1379
    If the issue persists, try the troubleshooting steps I have attached below.
    Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
    After waking from sleep or starting up, your computer may not show that it is connected to a Wi-Fi network.
    After start or wake, your computer may indicate that it is connected to a network, but does not connect to the Internet.
    Solution
    Use these steps if your computer does not automatically connect to your desired Wi-Fi network.
    Check your TCP/IP settings in the Network pane of the System Preferences. Click the "Renew DHCP lease" button
    Choose System Preferences from the Apple menu.
    Choose Network from the View menu.
    Select Wi-Fi, then click the Advanced button in the lower-left hand corner of the screen.
    Click the TCP/IP tab from the top of the screen.
    Click the "Renew DHCP lease" button.
    Select the Wi-Fi tab and view your Preferred Networks list.
    Select each network and click the minus sign to remove those networks from your Preferred Networks list.
    Click OK and close the Network preferences.
    Remove your stored network passwords using the Keychain Access Utility.Restart your computer.
    Open Keychain Access from /Applications/Utilities. Your window will look like this:
    Remove your AirPort network passwords from the login keychain: Select the "login" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".
    Remove your AirPort network passwords from the System keychain: Select the "System" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".
    Note: The above steps will remove your Wi-Fi network passwords. If you do not know them, or if your network does not use passwords to restrict access, you should contact your network administrator.
    Join your Wi-Fi network. You will need to enter your password for your network again if it requires one.

  • Freeze after waking from sleep mode on MBP retina

    After waking from sleep mode my MBP retina freezes for 3-5 seconds. Mouse and touchpad don't work. I wonder if it's mountain lion problem or hardware problem. Anyone faced this?

    Just got a brand new model and OS X 10.8.2 (12C3012) and face the same issue, almost everytime it sleeps for too long. This is not a 3rd type SDD, this is a standard Apple SSD. I turned off the BT, I removed the almost every option from the battery saver mode. The current test is to disable the power nap - I will let you all know the result in a few hours.

  • My zero Key isn't working after waking from sleep mode. This is a real problem for me because my password contains a zero

    My zero Key isn't working after waking from sleep mode. This is a real problem for me because my password contains a zero.  I don't recall spilling anything or jamming it just that it worked before I closed the computer and wasn't after I woke it up.
    I would like to fix the key but if that's not possible right away , Is there a way to reset my password without being able to type with a key thats in it?

    Start by swapping the keyboard. You don't need to spend a fortune, and handy to have spare. USB cables can be bad even new.
    When I had some problems Apple wanted to blame the mouse, keyboard, cable, but in the end I found
    A. run Disk Warrior
    B. Corrupt pref or conflict with version of Hardware Monitor and other background tasks

  • Satellite A660-18N - Powers off after waking from sleep mode

    My Satellite A660-18N powers off 2-3 seconds after waking from sleep mode. I upgraded the memory from 4GB to 8GB, using Crucial's website, so I know it's compatible. BIOS is updated to 2.00.
    Not sure what to do, how can I fix this without turning off Sleep mode completely?

    Hello
    >Currently I've turned off sleep mode altogether. I've also reset the BIOS settings from the boot menu but it hasn't fixed the problem
    And why you dont test it with pretested memory modules from an authorized service provider? The part number for such RAM is PA3677U-1M4G. Its one 4GB DDR3-1066 MHz memory module.
    Furthermore it would be interesting to know who says that Crucial memory is compatible Maybe its compatible to other Toshiba notebooks but fact is you have problems after waking from sleep mode and this happens only with Crucial memory and not with preinstalled modules.
    I dont think somebody here can provide you a solution for this because its just a compatibility issue and its user to user forum only.

  • My desktop background disappears after waking from sleep mode

    My desktop backgroung disappears after waking from sleep mode. Just converted to Lion.

    I spoke with Tech Support this morning. Apparently this is a known issue with Lion. I found it interesting that the rep insisted on saying that "it is the way Lion functions" instead of admitting that it is a GLITCH in the programming. He even said that it happens randomly and not on all computers and not all users experience this. That ought to tell you that it's a glitch.  Anyway, there is a "workaround" which is what you do to put a bandage on a persistent wound that should really get surgically stitched:
    You either have to log out every time you leave the laptop, or you have to change Energy saver preference to set the display to go to sleep AFTER the computer is set to log out (in Security preferences).
    Here is the article that instructs us on applying the bandage::

    Suffice it to say that Apple does not plan on stitching this one up any time soon..

  • SMB shares die after waking from sleep mode

    When my Macbook is freshly booted, I can access the SMB shares on my linux server just fine. The fun starts when the computer is put to sleep and then awakened. About 50% of the time, the shares on my server are inaccessible after waking from sleep. When I click on the server in the Finder, it just says it's connecting and sits there. Not only are the shares inaccessible, but the server cannot be "ejected" (Item in use). Plus, the system cannot be rebooted nicely. It just hangs with the spinning wheel until I ctrlcommandreset the thing. Other services on the server remain accessible from the Macbook after samba dies (iTunes library, FTP). Occasionally, the shares will come to life if I sleep/wake the computer again, but that is rare.
    Tiger worked fine with the same server, it wasn't until the 10.5 upgrade that I began having trouble. I called Apple tech support about the issue, and waited 2 weeks for them to tell me to "install Bonjour on the server." I have formatted and reinstalled Leopard more times than I care to count, but the problem always remains. I've been dealing with this for almost a YEAR now and am totally desperate for a solution. Has anybody ever heard of this before?? The server is running Clarkconnect (Centos derivative).

  • My iMac won't automatically connect to wifi after waking from sleep mode

    After dowloading the newest software update and performing a firmware update for my Airport router, my Imac won't connect to Wifi automatically after waking from sleep mode

    Please re-download and install the 10.7.3 update. You can locate it at 10.7.3 (Client Combo). Follow the on-screen instructions. Then test it out, if you still have the same problem please restart, when you hear the startup tone hold down the Option Key and then choose the Recovery Partition. Then open Disk Utilities and Repair Disk Permissions 2x. Then exit DU, restart normally and re-test.

  • Macbook pro screen dims after waking from sleep?

    Does anyone know why my macbook pro screen dims when waking from sleep or waking from my screen saver? I can't get it to stop doing this. Thanks.

    It sounds like I have the same thing happening. It's more like the colors are washed out, like there is less contrast. I have a hot corner set up for my screen saver. Once I activate the screen saver for a second and then deactivate it, the Macbook screen goes back to normal. I have a 30" Samsung 305T monitor set up as a second (main) screen for when I'm working at home, which is most of the time. I haven't had it unplugged from the Macbook since this started, so I don't know if it happens by itself. I do know that the Samsung looks fine when waking up from the screen saver at the same time.
    I tried to find others with this problem in this forum, but got tired of looking through all the other posts that had nothing to do with this problem.
    Can anyone help us?

  • Anyone's MacPro have problems after waking from sleep mode?

    After waking from sleep, my MacPro 2x2.4 Quadcore Intel Xeon freezes in several applications that had been running before sleeping. Mail and Firefox both get into endless loops trying to download data and will not force quit. Pulldown restart and shut down do not function when this is occurring. Must shuyt down manually from box and start again. Everything works fine again until it goes to sleep again.

    Start by swapping the keyboard. You don't need to spend a fortune, and handy to have spare. USB cables can be bad even new.

  • Bizarre app behavior after waking from Sleep Mode

    My iMac Core Duo runs like a top. It is fast and quiet. I have no problems with applications, both Universal and PowerPC. I maintain it with everything that I suggest others do in posts.
    But, there is this one strange quirkiness that I have put off mentioning because I kept hoping that each new OS X update would address the issue. It has to do with waking my Mac from sleep mode with it logged into my user account. Not every time, but most of the time, if I put my Mac to sleep or it goes to sleep from inactivity while it is logged into my user account, I experience strange application behaviors upon waking.
    For example, upon awaking Mail.app will contact my .Mac account and download any new mail that has arrived. But, if I try to open any of this mail, instead of opening, Mail.app will open a new outgoing email addressed to whomever sent me the mail I tried to open. Quitting and restarting does not solve this problem. Other apps demonstrate similar bizarre behavior. To only way to solve the issue is to log out and back into my user account.
    However, if I log out of my user account and then put the Mac to sleep from the Login Manager I don't experience this issue. So at night I always log out before putting the Mac to sleep.
    Anyone else experiencing similar issues? Any ideas on solving this? Do you think it is a bug in Universal Mac OS X?

    Sorry this isn't a solution, rather is a commiseration. Often after my iMac wakes from sleep mode it refuses to see my internet connection. I have to unplug and reset my DSL modem to force the computer to see that it exists.
    It sounds like the problem might be related, does anyone have any brilliant suggestions?
    Thanks,
    Lonnie

  • Wifi/System Preferences Freezes After Waking From Sleep Mode.

    Every since I installed Mountain Lion, I've had the issue of my MacBook Pro freezing up while it checks for Wifi after waking up from sleep mode. I have to constantly restart my computer. I'm wondering if Apple is aware of this happening on other computers and not just mine.
    Also, my laptop is considerably slower since installing the OS update, especially when I turn on my computer.
    - Rog

    !!!!!!!!!!!So far only this has worked for me!!!!!!!!!!!!!!!!
    Go to System Preferences -> Energy Saver -> and UNcheck the box that says "Put hard disk(s) to sleep when possible on BOTH the Battery and Power Adaptor tabs.
    I had this issue when I first installed Mountion Lion on my Aluminum MB 2008. Thought it was 10.8 so I down graded to 10.7 Lion, issue still happened. But after I applied this setting the issue seemed to go away. Before this I also deleted the old wifi settings in Network Utilities and added the Wifi device, ssid, and wep key again (not using WPA2). I will continue testing through the night and will update once I can determine the issue is gone.
    Hopefully this works for others too.
