How to wake from sleep only with power button

Hi,
I still use this old PowerMac G4 (hopefully Apple builds a new MacPro soon!) and when not using it, it is in sleep mode.
Unfortunately my cats like to touch the keyboard, thus waking up my Mac.
Is it possible to wake the mac only by pressing the power button?
If so, how?
regards

The USB bus is unique from other buses in that it always has power present to it.
Because of this, it can be used to sense activity at a keyboard or other input device to facilitate wake from sleep.
The power button also always has power present, with the main purpose of on and off being extended to options for sleep and wake. This is possible due to the use of a momentary contact switch, with fuction that can be interpreted (time held) for various purposes via software.
why the action on the USB bus has to be a keyboard inpput, but not a mouse click. strange.
Mouse click should also wake the machine if the mouse is USB. If Bluetooth, an option must be selected in the software, and then not all mice are equal.
If wireless, then, again, not all are equal. Some will wake a machine, others won't.

HP Envy 14 (2020NR) - randomly missed keystrokes after wake from sleep (on battery power only)

While running on battery power, sometimes when I wake from sleep, keystrokes will randomly be missed. It doesn't always happen, and I need to do more experimentation to figure out just how often it occurs. To fix it, I just reboot the computer (while still on battery power), and the problem seems to be gone. It can also be fixed by simply plugging in to A/C power. I am using Windows 7 Home Premium 64-bit.
I have seen similar threads where people say that repeated keystrokes are missed, or rapid keystrokes are missed -- but so far those threads have remained unanswered, and my problem seems a little different in that no one else has mentioned a correlation with running on battery power. The problem never occurs otherwise, for me.

If you are still under warranty you need to return the laptop for service. If not I am afraid it is a motherboard issue requiring replacement. You have done all the diagnostics a professional would do. The fact that the battery works in another computer tells us it is not the battery.

Powermac G4 : Wake up only with Power Button

My Mac used to wake up with just moving my Logitech USB Mouse until the fans went haywire. Now only by pressing the Power button, does the Powermac G4 wake up. Fans have been changed, Hardware test and Memory test have been run, still no change. Any suggestions how to restore the wake-up to previous state. Thanks.

whether using NVRAM or PRAM, the Powermac G4 reverts to Panther on restart. I am told this is normal.
That sounds like a dead or weak PRAM battery. "Normal" is that the computer remembers its startup volume settings. Are you unplugging the computer from wall power? What you see can be a symptom of having a dead PRAM battery combined with pulling the plug out of the wall every night. Turning off a power strip of backup power supply has the same effect.
There are a number of G4 variants and I've not yet seen a mention of which G4 variant you're working on. The later Mirrored Drive Door G4s do better with both drives set to cable select. The older variants retain the older "master/slave" relation for drives. Do "About the Mac..." then click on "More Info..." in the resulting window. Copy/paste the "Hardware Overview" info from the next screen into a post here, deleting your serial number. That screen for my G4, an MDD, looks like this:
Hardware Overview:
Machine Name: Power Mac G4
Machine Model: PowerMac3,6
CPU Type: PowerPC G4 (3.3)
Number Of CPUs: 1
CPU Speed: 1.25 GHz

L3 Cache (per CPU): 1 MB

That might help us work througha n model-specific issues.
What kind of keyboard do you have the requires USB 2.0? Most are slow devices and more than hapy on a USB 1.1 port.

Anyonr else experience wake from sleep issues with early 2009 mini?

I have my early 09 mini attached to a 22" Samsung monitor vis the mini dvi-dvi adapter. This morning i went to wake the monitor and it responded right away normally but then went black. I tried to wake it again i got a screen that was just noise. Like the photoshop noise filter. It required me to hit the power button on the monitor and then it cleared up.

I would like to share that I also have experienced display problems with my Mini. My problem was that when my mini would put my monitor into power save mode, the screen would display a noisy picture when returning out of power save. Sometimes it would clear up on its own quickly while other times the problem would persist until I put the mini fully into sleep mode and then wake it up again. I have since taken my monitor and mini to the Apple store where the Genius Bar examined the problem and gave me a new Mini. The new one is still sealed and sitting in my office. I'm skeptical that it will perform any better. I know for a fact that my monitor is in good working order because it is currently running on another PC and has never shown signs of being faulty. For the record, the LCD I own is a 25.5 inch Asus monitor connected to the mini using the mini-dvi to dvi adapter. At the apple store they tried the mini-display port to dvi adapter and the same problem occurred. I'm really hoping that the display issues can be fixed with a software update. I've read on a number of forums that mini owners have complained about the noisy picture when coming out of power save mode. It's clearly a common problem and I would have to assume that Apple is aware of it by now.

How to make iBook sleep automaticlly when power button is pressed?

I have an iBook G4. It had Tiger on it, then I took it apart to replace the hard drive and ram, and put Leopard on the new hard drive.
Now, it doesn't sleep when I close the lid. I can't find a setting that changes this, so I'm assuming something happened when I took it apart.
But also, now when I press the power button, it brings up a prompt that asks if I want to sleep, shut down, or restart. It's pesky because what used to be just closing the lid is now a button push, pointing, clicking, and then closing the lid. When I had Tiger it would just sleep automaticlly when I pushed the power button. Is there any way to get it to do this again? Or perhaps something I overlooked that changes what happens when I close the lid?

Hello,
Check you have the correct options set in system preferences under 'Energy saver'.
Just make sure it's not set to sleep 'Never'
Seeming this iBook has been opened, it could be a problem with the magnet used to trigger sleep mode when the lid is shut.
Regards to setting the options for the power button, this is defined by the version of OS you have installed.
From what I recall, the screen options were available from Mac OS X 10.5 when you pressed the power button.

Late 2013 Mac Pro wake from sleep crashes - which logs to look at?

I started encountering wake-from-sleep crashes with my late 2013 Mac Pro a couple of weeks ago. Prior to that the system had been pretty solid. Other than app and OS updates installed from the App Store, I can't think of any software changes that might be responsible.
What logs should I be looking for that could be helpful in diagnosing the problem? Looking at other posts where people have been trying to diagnose similar issues I see people posting portions of panic logs that show which modules were loaded and might help point to a culprit, but I can't seem to find a log with a panic message in it.
I had thought I'd determined my Anker USB3 powered-hub was related to the crashes, as when I disconnected it from my system I went several days without a crash. Today I reconnected the hub with just a few devices on it and got a crash. I disconnected the devices but left the hub attached but got another crash. I then disconnected the hub again, assuming I'd proved it was the culprit, but the machine has now crashed twice without the hub attached.
I'm running OS 10.9.4. Looking at other reports people reported some specific programs that added kernel extensions that were suspected to be the problem, but I don't have any of those programs installed on my Mac. The problem doesn't happen every time I wake the machine, but has happened at least four times today alone (after about three days of no crashes.)

Twist BIOS 1.65 wake from sleep causes port replicator failure

Recently, I updated my Thinkpad Twist to BIOS 1.65. After the update, my Targus ACP70US USB 3.0 port replicator / dock (video, audio, Ethernet, USB hub) would not reconnect after waking from sleep. Unplugging and reconnecting the USB connector would do nothing. The only way to get the port replicator to work was to do a full reboot. I'm running Windows 8.1 x64.
I can confirm that this is a new problem specific to BIOS 1.65. Downgrading to BIOS 1.63 resolved the issue--the port replicator works fine & wakes from sleep properly with this BIOS revision. And yes, the Targus dock has the newest firmware & the Windows drivers for it are current...
I didn't bother trying to see if any other USB device would fail in this way or if it's something to do with this specific Targus device...
Maybe the following change may have something to do with the regression: - (Fix) Fixed an issue the computer might not resume normal operation from suspend state.

Albert, go to http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS032000 , which is the download site for the latest BIOS update. Scroll near the bottom of the page and you will find all the previous versions of the BIOS files that you can download. Just select the file and it should begin to download.

APC SmartUPS SUA1500 - Supports wake from sleep surge?

In the past there was a great deal of discussion related to the Mac Pro's surge current, upon waking from sleep, causing an attached UPS to report an overload condition. Several users stated that the APC SmartUPS model SUA1500 doesn't exhibit this behavior.
With the passing of time does this still hold true? If not what are people using for a UPS to support the Mac Pro's large surge current requirement upon waking from sleep?

There are two different considerations. The first related to if the UPS can support the Mac Pro once the machine is running (e.g. a power failure occurs when the machine is running). The second case is where the machine needs to wake from sleep during a power failure (e.g. UPS signals the Mac Pro that a power failure occurs via USB, thus causing the machine to wake to process the event).
In the second case the Mac Pro does nothing to limit the amount of current (power) drawn from the UPS thus perhaps causing the UPS to claim an overload condition.
On my current setup my UPS supports the first case with no problems. On the other hand I have tried two different UPS systems to support the second case. Unfortunately both UPS systems shut off power to the Mac Pro claiming an overload condition (in fact my Powerware UPS claims the output is shorted when the Mac Pro comes out of sleep).
When you say that you have no problems with the lower cost APS UPS, have you tested the second (wakeup) case I cited above? Note that the machine needs to be in sleep for a period of time to permit for this to occur.

Lion very slow to wake from sleep

Since performing a clean install of 10.7 (now at 10.7.3), my MacBook Pro takes several minutes to wake from sleep. With Snow Leopard it would take seconds. The settings in the preferences are the same. It also does another strange thing: When waking the screensaver, the screen freezes and, using my mouse, drag it around until I find my login icon... The mouse leaves a trail behind it - kind of like an etch-a-sketch does. I ran disk utilities and, although it found numerous problems and repaired them, it is still acting strange. This is annoying... I'm tempted to go back to Snow Leopard. Any ideas?

Try resetting the SMC. http://support.apple.com/kb/HT1806

Computer won't start & fails to wake from sleep

First post -- I have a 2009 HP Pavilion Elite w/Windows7. Good box & OS, never a problem until now. Started about a month ago w/the box not waking up from "sleep" -- no response (power light turned from amber to blue as usual but nothing else happens). Had to turn it off, but then won't come back on! After 10-15 minutes of repeated power-on button presses, it starts back up. Removing/reinserting the power cord during trys doesn't help. Occasionally it starts right up from sleep, but usually has this problem. Windows7 is up-to-date and no viruses or malware detected. HP or Microsoft diagnostics show no issues.
I opened the box to clean out dust -- also took off the CPU heatsink (really dusty) & cleaned it too. Fans rotate easily & aren't an issue.
So now I have "sleep mode" turned off, but occasionly the box has to be turned off & afraid it won't come back on. I've seen some of the HP videos & will try shorting the two start-up pegs on the MBoard, but the power-switch was hardly ever used & I seriously doubt that's the problem -- it wouldn't have anything to do w/the sleep-wakeup problem. Any suggestions?

No wake from sleep with upgrade to 10.10.3

I recently upgraded a new iMac Retina 5K to Yosemite 10.10.3. Since the upgrade, the iMac will no longer wake from sleep. The screen remains black. I have to hold the power button for several seconds to reboot the machine. I am using the standard Bluetooth keyboard and Trackpad.
I have tried reseting the SMC, PRAM, and booting into Safe Mode (none of which fixed the problem). I know I can turn sleep off via Energy Saver, but my workflow makes using sleep a better option for me.
I looked in the system logs and find a dozen of the following messages after I try to wake from sleep:
Apr 12 12:10:12 iMac kernel[0]: **** [IOBluetoothHCIController][TransferACLPacketToHW] -- commandSleep(&mSystemOnTheWayWakingUp) failed -- counter = 1 ****
Apr 12 12:10:22 iMac kernel[0]: **** [IOBluetoothHCIController][TransferACLPacketToHW] -- commandSleep(&mSystemOnTheWayWakingUp) failed -- counter = 2 ****
Apr 12 12:10:32 iMac kernel[0]: **** [IOBluetoothHCIController][TransferACLPacketToHW] -- commandSleep(&mSystemOnTheWayWakingUp) failed -- counter = 3 ****
Apr 12 12:10:42 iMac kernel[0]: **** [IOBluetoothHCIController][TransferACLPacketToHW] -- commandSleep(&mSystemOnTheWayWakingUp) failed -- counter = 4 ****
Apr 12 12:10:52 iMac kernel[0]: **** [IOBluetoothHCIController][TransferACLPacketToHW] -- commandSleep(&mSystemOnTheWayWakingUp) failed -- counter = 5 ****
Apr 12 12:11:02 iMac kernel[0]: **** [IOBluetoothHCIController][TransferACLPacketToHW] -- commandSleep(&mSystemOnTheWayWakingUp) failed -- counter = 6 ****
Anyone know what the problem is and how to fix it?

Step 1
Take all the applicable steps in this support article. That's the starting point for any further efforts to solve the problem. Please read the whole article carefully and don't skip any of the steps, including the ones under the heading Additional troubleshooting. If you don't understand any of the steps, ask for guidance.
Also note that if you replaced the internal hard drive with an SSD, or if you're starting up from an external SSD, then that device may be causing the problem. Check the SSD manufacturer's website for a firmware update. The only solution may be to reinstall the original drive or avoid sleep altogether.
Step 2
If you're running OS X 10.8.5 or earlier, from the menu bar select
           ▹ System Preferences... ▹ Accessibility
If the checkbox at the bottom marked
          Enable access for assistive devices
is checked, uncheck it and test.
If you're running OS X 10.9 or later, select
           ▹ System Preferences... ▹ Security & Privacy ▹ Privacy ▹ Accessibility
If any applications are listed on the right and have a checked box next to them, uncheck all the boxes and test. You may first have to click the padlock icon in the lower left corner of the window and authenticate as an administrator to unlock the settings.
Step 3
In the Energy Saver pane of System Preferences, uncheck the box marked
          Put hard disks to sleep when possible
Step 4
If you don't already have a current backup, back up all data, then reinstall the OS.* You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode. All other data will be preserved.
*The linked support article refers to OS X 10.10 ("Yosemite"), but the procedure is the same for OS X 10.7 ("Lion") and later.
Step 5
This and the next step must be taken as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ Diagnostic and Usage Messages
In the search box in the window's toolbar, enter "powerd" (without the quotes.)
You may see one or more lines like this:
com.apple.message.signature: Platform Failure
If you do see that, and you did everything in the preceeding steps, then you're dealing with an internal hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
Step 6
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that heading, select
          View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down.
You may see one or more reports with a name that begins with "Sleep Wake Failure" followed by a date. Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.

Power Mac G4 Wake from Sleep Crash

I have been having wake from sleep issues since I installed Mac OS 10.5 on my Power Mac G4 three months ago. Technically, this machine is supported by Leopard: it's an 867 MHz G4 with 512 MB of RAM. And indeed, the Leopard installer allowed me to install fine, and while it runs slower than I'd like, it seems to run all the applications just fine. The major problem is that it does not properly wake from sleep. Nearly every time the machine wakes up from sleep, it crashes and needs to be rebooted. It may be a display issue -- the screen frequently looks corrupted when it has crashed -- but the console logs have not given me any clues. It does seem to be related to the amount of time that the machine has spent sleeping, but I have had it crash after a sleep of as little as a few minutes. I have a USB 2.0 PCI card installed, but removing that for a week didn't have any noticeable effect on the problem. I'm stumped, and preparing to downgrade to 10.4, as the machine takes too long to boot for me to live with the option of shutting down and starting up every time I use it.
I've been very happy with this machine for years and years and frankly I've never had this much of an issue with the Mac OS on an allegedly "supported" machine. As a last resort, I thought I'd ask here whether anyone has another idea that I can try.

I'm having a similar problem, though with my Powerbook G4, since installing Leopard. It's a 1.5 Mhz model. Everything seems to work properly, but it takes 10 to 12 seconds to wake from sleep. When it is woken, it shows the old screen image and remains frozen for over 10 seconds, before displaying the updated screen and coming back to life. It seems to me that this pause is progressively getting longer. It was only a few seconds to start with, but is now over 10 seconds.
Any clues?

TS4080 apple thunderbolt display image on display intermittently goes dark, does not wake from sleep after clicking mouse or keyboard, but there is "bonk" sound after clicking mouse or pressing keys. Rebooting by pressing the power button resolves issue.

My apple thunderbolt display (which I purchased 1.5 years ago; OS 10.7.5 Mac Mini) intermittently goes dark, does not wake from sleep after clicking mouse or keyboard, but there is "bonk" sound after clicking mouse or pressing keys, so am thinking it is a hardware problem with the display. Rebooting by pressing the power button turns the screen back on, but the same phenomenon has occurred several times. Could this be a software issue, or do I need to have my display repaired? Your feedback would be appreciated.

Hi ED, tough to tell, but it does sound like it's waking with the bonk, just not displaying.
Long shot but...
I wonder if it's a variation of this, of which I've seen many different symptoms...
Resolution
Move the mouse or trackpad cursor over the center area of the login window so you can see the user icons. Click on the icon of the user that you would like to login as, type in the user's password, and press Return.
If the login window is configured to show only the name and password fields, type in the user's name and password into the fields, and press Return (even if you cannot see the rest of the login window).
Additional Information
This issue will not occur if the display is not sleeping when the account is logged out. Use the steps below to confirm that the account is not configured to log out automatically while the display is sleeping:
1. Open System Preferences > Security & Privacy > General. Click the padlock to unlock the preference pane and enter your admin password. Click the Advanced button at the bottom, then see if the option "Log out after N minutes of inactivity" (where N is the number of minutes) is enabled.
2. Open System Preferences > Energy Saver and configure Display Sleep to occur after the account is logged out, by dragging the slider to a number of minutes that is greater than N was set to in the previous step.
Important: If automatic log out is not needed, disable "Log out after Nminutes of inactivity" in System Preferences > Security & Privacy > General. This will also prevent the issue.

27" iMac only wakes from sleep on second attempt

My 27" iMac, as the title suggest only wakes from sleep on the second attempt. If I wake the mac in the usual way(magic mouse, keyboard or power button), I hear the hard drive start but the screen stays blank. If i then press the power button it will put the mac back into sleep then if i then wake it up again everything comes on fine. This only seems to happen if the mac has been sleeping for longer than a few minutes, but it does happen every single time.
I've obviously checked that the bluetooth devices are allowed to wake the machine. Ive been looking through various forums and haven't come across anyone with the same problem as me so far.
Ive already tried resetting the smc,pram etc to no avail.
Any ideas on what could be the problem?
Thanks

Sorry, I get it now.
If you are using the Screen Saver prior to auto-sleep, then try disabling it to see if that helps.
If not then the only other thing I can suggest is to backup and reinstall the OS X or call Apple Support.

My iMac has suddenly become very slow to wake from "sleep." Why? How can I fix this?

My iMac has suddenly become very slow to wake from "sleep." How do I fix this and what is causing the problem? Even the mouse wakes very slowly.

Try these basic troubleshooting steps.
1. Quit all app scompletely and restart the iPad. Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar. Restart the iPad.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
2. Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
3. Go to Settings>Safari>Clear History, Cookies and Data. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
