    Our MAC also won't go to sleep most of the time. Unpredictably, it sometimes does. It is a 933 MHz PowerPC G4 / 2 MB L3 cache running on OSX10.4.11. I've tried unplugging USB stuff, restarting, ensuring a charged motherboard battery, holding the PMU reset button for 30 seconds after a total power off and cable disconnect, a different keyboard and mouse, with and without Bluetooth - nothing helps. It just sometimes goes to sleep and sometimes does not. Local technician is willing to try to help but admits it is a complex situation with a small chance he can duplicate, identify and fix. I can understand when something stops working because it is worn out or breaks. But this is intermittent and seemingly unpredictable. An online search suggests it is a known problem.

External drives (hard drive, DVD burner, iPod, USB drive), printer, a worn out mouse button, debris in/on the keyboard, and cats are all things that can cause your computer to refuse to sleep (or wake it shortly thereafter).  Rule out these first.  I have had the same problem in the past.  It is almost always one of these that causes the problem.

Computer won't come out of sleep


Sleep Mode Problems on a Dell Computer b> When Microsoft patched the power-saving features of Windows XP Service Pack 3 and Windows Vista, certain Dell computers were affected by various issues where the computers would go into sleep mode and be unable to come out of it or error out and not go into sleep mode. Sometimes the computers would go into sleep mode and wake up only when a USB mouse was jostled. Pressing keys on the keyboard would not wake the computer because the keyboard would stop functioning

Open the Dell support page on your Internet browser. See the link Below . http://support.dell.com/ Make sure to have your seven-digit alphanumeric (letters and numbers) service tag. Place that information into the "Choose by Service Tag" option. Make sure that the option for the "Operating System" is correct. Go to "+Bios" and click on the "+" symbol. Click on "Download" at the far right, save and run the downloaded file. Restart your computer after installing the file. Test the "Power-saving" feature once you have rebooted. b> If Section I Does Not Resolve the Issue Go to "Display Properties" by right-clicking in an open area on your desktop and left-clicking on "Properties." Click on the "Settings" tab. Check if the "Display" midway down is saying "Plug and Play Monitor on..." If it is not, go to the "Device Manager." Left-click on the "X" in the top right corner of the "Display Properties" menu. Go to "Start," left-click, and then open the "Control Panel" (or "Settings" and then "Control Panel" depending on your system is set up). Select "System," go to the "Hardware" tab, and left-click on it. Left-click on "Device Manager" about 1/3 of the way down that page. Look at "Monitors" and see a "+" symbol. Left-click on it once and see if it has an exclamation point,"!," with a yellow circle around it. If it does, right-click on the "Plug and Play Monitor" and left-click on "Update Driver." Choose "Yes, this time only" and then left-click on "Next." The wizard will update the monitor drivers automatically, if possible. Restart if necessary once updated. Test the"Sleep" mode again. The computer should go into sleep mode and then wake up successfully. b> If Section I and II Do Not Work Left-click on "Start" and then "Control Panel" (or "Settings" and then "Control Panel," depending on your system's setup). Double-click on "Power Options" to open it. Open the "Hibernate" tab and click on "Enable Hibernate." You may have to reboot again. Test the "Sleep" mode function again. b> Windows Vista Open the Dell support page in your Internet browser. See the link Below. http://support.dell.com/ Make sure to have your seven-digit alphanumeric service tag. Place that information into the "Choose by Service Tag" option. Make sure that the option for the "Operating System" is correct. Go to "+Bios" and click on the "+" symbol. Click on "Download" on the far right. Save and run the downloaded file. Restart the computer after installing the file. Test the "Power-saving" feature once you have rebooted. b> If Section IV Doesn't Work b> Reboot the system and press "F2" or "Del" to get into Bios. Make sure that the "Legacy USB" option is enabled. Save and exit the Bios and start Windows Vista. Go to "Start" and then "Control Panel." "Switch to Classic View" on the left side. Click on "Power Options." Click "Change Plan Settings" and then "Change Advanced Power Settings." Set the "Sleep>Sleep After" to "Never." Set the "Sleep>Allow Hybrid Sleep" to "Never." Set the "Sleep> Hibernate After" to one minute after the monitor and hard drive are set to turn off. Set the "Power" button and "Lid>Start" menu power button" to "Hibernate." Restart the computer and test the "Power Sleep" mode. b> If Section IV and V Do Not Work b> Find the "Windows" sidebar at the bottom right corner. Right-click on it to disable it. Test the "Sleep" mode again. If the computer does go to sleep, enable the "Windows" sidebar by going into the "Control Panel" and enabling it again. Start turning off each gadget one by one, and test the "Sleep" mode to see which gadget is causing the problem. Look at the system and see if you have a "Google" sidebar." If you do have Google sidebar, then pick only one to use, or choose not to use either of them. To remove the "Google" sidebar, left-click on "Start," then left-click on "Control Panel." Double-click on "Programs and Features." Wait for the computer to populate installed software on your computer. Find the "Google" sidebar and remove it by left clicking on it and left click "Uninstall." If you want to remove the "Windows" sidebar, right-click on it, left-click on properties to open "Properties," then remove the check from the "Start Sidebar When Windows Starts," selection and click "OK." Disable Sleep Mode Microsoft Windows 7 uses sleep mode for desktops and laptops to save power during times when the computer is not in use but does not need to be shut down. Sleep mode pauses and suspends your computer until you are ready to continue. In some cases, sleep mode interferes with scheduled tasks or operations such as remote desktop connections. Microsoft allows sleep mode to be turned off and disabled for users that have no need for the function or find that the feature is interfering with their normal computing activities.

Click the "Start" button to expand the Windows "Start" menu. Select "Control" panel in the right column of the "Start" menu and click "System and Security." Click "Power Options" and press the "Change Plan Settings" link next to your computer's currently selected power management plan. Select "Never" from the "Put The Computer to Sleep" drop-down menu. Select "Change Advanced Power Settings" beneath the "Change Settings For The Plan" heading. This launches a "Power Options" panel. Double-click "Sleep" in the menu tree to expand the advanced "Sleep" options. Select "Sleep After" and use the arrow to select "Never." Select this option for both "On Battery" and "Plugged In" if you are configuring power options on a laptop. Click the small "plus" icon next to "Hibernate After" to view hibernation settings. Click the arrow to select "Never." Select "Never" for both "On Battery" and "Plugged In" if you are configuring your power options for a laptop. Click "OK" to close the advanced power options. Select "Save Changes" to save your new power management configuration. Your computer's sleep mode is disabled.

Hope it helps.

Prostart 6 button in sleep mode


Sleep mode is a convenient power-saving feature used on both laptops and desktop computers. This feature powers down hard disks, monitors, wireless devices and any other power-consuming peripherals without turning the unit completely off and necessitating a reboot. Sleep mode can prevent battery drain if using a laptop or mobile device while away from the power supply. This mode is useful when quick access to a computer is needed, but can be irritating if the sleep mode takes a long time to come back from. It is simple to turn sleep mode off, based on the operating system being used.

Go to the "Start" button, then click on "Control Panel." In the control panel screen, click "System and Maintenance," then click on "Power Options." This brings you to the "Select a power plan" page. From the "Select a power plan" page, select the option that says "Change plan settings." This changes the settings on the currently selected plan. Select the "Change advanced power settings" option. Click "Sleep" and then click on "Sleep After" to expand it. If using a laptop or mobile PC, click "On battery" and "Plugged in," then select the "Never" option. This turns off sleep mode for both battery and AC use. If you are using a desktop computer, click "Setting," click the arrow and then click "Never" to turn off sleep mode. Click "OK," then click "Save changes" to save the modification. b> Turning Off Sleep Mode - Mac OS b> Click on the Apple logo at the upper left corner of the screen to open the menu and select the "System Preferences" option. From the "System Preferences" screen, click on "Energy Saver." If you are using a desktop, select "Power Adapter" in the top drop-down menu. In the second drop-down menu, select "Custom." Highlight the "Sleep" tab, then adjust the top slider to the far right, marked "Never." I f you wish the display to stay on, adjust the bottom slider to "Never." Click the red button on the upper left side of the "Energy Saver" screen. If you are using a mobile product or laptop, follow step 2 and select "Battery" from the top drop-down menu. Repeat step 3 to change the settings for battery use. Hope this helps.

Windows sleep mode problems


Sleep mode on a Windows 7 PC saves power without you having to turn your computer off and without losing any work. This option cuts the power to your monitor, powers down the hard drive and pauses all functions until you awaken the computer from hibernation. Whether you have a laptop, desktop or workstation, putting your computer into sleep mode will lower your electric bill and save money! Click the "Start" button in the lower left corner of your desktop. In the lower right corner of the Start menu, next to the "Shut Down" button, is a button labeled with a small, right-pointing arrow. Mouse over the arrow. The Shut Down menu appears. Point at "Sleep" and click on this option. Your Windows 7 computer goes into sleep mode. Wake your computer from sleep mode by jiggling the mouse. There may be a delay of a few seconds before your hardware powers on. All of your open programs are still open and your work is intact, just as you left it before the computer entered sleep mode. Configure your Windows 7 PC to go into sleep mode automatically when it is not used for a certain amount of time. Click "Start" and select "Control Panel." Click "System and Security." Click "Power Options." A menu opens. Click on "Choose when the computer sleeps" and select the number of minutes of inactivity. You can also set a separate time interval to put your monitor into sleep mode. If you set both to 10 minutes, then your PC and monitor will automatically go into sleep mode after 10 minutes of inactivity

I am unable to access the internet from sleep mode Can only get on internet from shut down mode


Three possible causes of sleep mode. first, an extensive screensaver with password lock prevents display. A condition that is observable as a blankscreen also known as sleep mode. Second, a computer power saver settings that shutsdown during idleness. Third, An improper shut down of the computer would have caused a sleep mode to save the system data files.



Restoring the computer to regular functionalioty

First solving predictable sleep mode settings
1. A movement of mouse pointer across the screen should reestablish unprotected password modes
a. password protected sleep mode would display an promp message requiring key code soon after the mouse pointer has changed direction

sloving unpredictable sleep mode settings
1.A computer power saver, screen saver, or splash screen displays prevnting programs acess would require manually powering off the computer system.
a. A manual power back on of the system should restore to program functionality mode

Two Mac Pro's in our office have started freezing on startup or shortly after. Both are running 10.4.11. Discs seem to test fine and Safe Mode works. Any ideas?


The problem could be the operating system you are running on the Macs. I currently have a Powerbook G4 that I was running Leopard on, the only problem is my computer didn't support leopard so I kept having to get the computer serviced. I eventually switched to the Tiger operating system and that solved it. Try changing the operating system, but make sure you have back everything up first. If you need to know how to do this, even if the computer won't turn on, I can provide detailed instructions, since I had to do this a month ago. Good luck.

Curious - What is the moon shaped key all about


this button puts the computer into sleep mode.

FROM WIKIPEDIA-

Sleep mode can go by many different names, including Stand By (Microsoft Windows 95-Server 2003), Sleep (Mac OS 8)-(Mac OS X) / (Windows Vista,Windows Server 2008), and Suspend (Linux). When placed in this Sleep mode, aside from the RAM which is required to restore the machine's state, the computer attempts to cut power to all unneeded parts of the machine. Because of the large power savings, most laptops automatically enter this mode when the computer is running on batteries and the lid is closed.
Though Sleep and Hibernate are generally thought as two separate functions, modern Macintoshes, Windows Vista (termed Hybrid Sleep), and some specially configured Linux machines also feature a variation of Sleep mode that incorporates the strengths of Hibernate. The RAM is copied to the hard drive before sleep mode is initiated, preserving the RAM contents in the event of a power loss.
ACPI is the current standard for power management, superseding APM and providing the backbone for sleep and hibernation on modern computers. Sleep mode corresponds to ACPI mode S3. When a non-ACPI device is plugged in, Windows will sometimes disable stand-by functionality for the whole operating system. Without ACPI functionality, as seen on older hardware, sleep mode is usually restricted to turning off the monitor and spinning down the hard drive.
