Won't wake up from sleep, sometimes get blue screen and can't get it to wor

I have two problems that may be related. I am using a PowerBook G4 (Tiger 10.4.5). Sometimes when I turn it on I get a blue screen and that's it. Nothing else will come up. I have to do a forced shut down and then restart it with the shift key depressed and run repair disk permissions and then it works okay till the next time it decides to return to the blue screen (once a day approx.).
Also, sometimes it goes to sleep and will not wake up. I have to shut it down and then restart it (sometimes getting the dreaded blue screen).
This just started happening after I installed Tiger.

As Adrian suggests, my "Troubleshooting Startup and Login Items" FAQ can help you determine which Startup or Login item is causing the problem.
2. As to the sleep problem, here are some ideas for you:2.1. If you are using a Bluetooth keyboard or mouse, see "Mac OS X 10.4 Help: My wireless mouse and keyboard won't wake my computer.".
2.2. Your Mac maybe frozen or hung. Troubleshooting freezes and hangs is not unlike troubleshooting kernel panics: the steps are virtually the same. For a more exhaustive troubleshooting procedure, you could use the steps in my "Resolving Kernel Panics" FAQ.Good luck!

Macbook (White - old model) - Won't wake up from sleep sometimes when I close the lid

Sorry if showing the specifications of my Macbook is necessary
But lately, when I'm just going to take a break from my Macbook for a bit, I just close the lid
Sometimes, I just return in 5 minutes, and open the lid. The black screen never goes away, and the sleep indicator light always is lit, and doesn't pulse.
Many times, I've had to reset my computer via holding the power button for 5-10 seconds, which is much more damaging than a clean shutdown.
This has accumulated damage to my battery (as shown by coconutbattery - it's been draining it from 97% (after calibration) to 91% (After calibration)) and who knows how much it's done since then?
Does anyone know how to solve this problem?

After doing the hard shutdowns (holding the power button for 5-10 seconds to force quit the MacBook) I would open Disk Utility and Verify the integrity of your File System with First Aid.....
.....I would try an SMC reset to see if the sleep issues can be sorted out....look under (Power) for the specific items that the reset helps....

Powerbook G4 won't wake up from sleep

My 4 1/2 year old powerbook G4 won't wake up from sleep anymore. After I close the lid, or even manually put it to sleep, I can still hear the HD run. The backlight on the top of the lid never lights up and when I open the lid the blank screen doesn't do anything. The only way for me to work around this issue is to power down the laptop and start it up again. Since I've been having this issue every program that I use take forever to load. The spinning color wheel is the bane of my existence! I tried resetting the PRAM, I used Onyx to repair file permissions, and am out of ideas. Any help would be greatly appreciated.

How incredibly strange. I am having exactly the same problems with my computer. I just started the same behavior today. I have tried using MacJanitor, repaired permissions, verified disk, but it still will not go to sleep properly. S.M.A.R.T status is verified
I have tested my RAM as described above with no problems surfacing. Anyone else have any ideas that we can try. When I get home on Sunday I will try some more intense investigative tools including re-installing OSX 10.5
By the way, I am running 10.5.4 on a 15" 1.5Ghz G4 Powerbook with 1.25GB of RAM and 28.9GB harddrive free.
Another strange thing I have also observed is that it now takes 10 minutes to start up. 5 minutes on the Apple screen with pinwheel, and then 5 minutes with the blue screen before the cursor appears. After that point startup is normal. Also, even though Disk Utility shows 28 GB free on my harddrive when I try to copy something, it says that I do not have enough free space on my harddrive.
Do you suppose this means that my harddrive is on the way out? Is this also the case of the original poster?

My mac won't wake up from sleep, what can i do

My mac won't wake up from sleep, what can i do

Can you say more about thermal cut-off? My mac has beene having problems waking from sleep and I have noticed that I hear the fan running ever so slightly in the background. When I depress the power button for a second the fan shuts off.
Just open the side an dlook to see which fan it is. The lower fands are easy to see as well as the video card fan.
When you push the power button and that fan goes off is the machine now fully off? No power light? No fans spinning? Now drives spinning?
I don't recall what I did when my machine shut off with the one exhaust fan running. I think the obvious thing I would have tried would have been to push power button for 10 seconds to shut it down fully. That or actually pull the plug.
When this happens the only way to use my Mac is to restart via the power button.
Then I guess that answers the first question. It must have turned off since pushing the power button again was the normal reboot.
I can't find any helpful info on thermal cut-off so I was wondering if you could explain what it is, what causes it, and more importantly what I can do to fix it?
That was my term for it. What else could it be? Without its fan video card would get extremely hot and throw off all that heat. Whats the point of having temperature sensors in so many places other than to use that info to protect the machine against damage due to overheating? So my assumption was card gets hot, sensor (probably the pci slot 1 temperature sensor) senses it, kills the machine. It's also seems logical to me that the circuit(s) handling temperature overloads would want to keep a exhaust fan running to dump the heat out of the machine to further protect any damage from the heat.

It won't wake up from sleep after I open it. If I close it and then open it, it doesn't wake up for at least 5 minutes.

just upgrade my macbook air to yosemite. now when i physically close the computer and open it back up, it won't wake up from sleep mode. I tried pressing the power button, but it wouldnt turn on. Then once it somehow turned on by itself, I tried a PRAM and SMC reset. Then I tried closing and opening the computer again and I still had the same problem. nothing has worked. when i do get the computer on, i randomly goes into sleep mode again. I've check the settings for display and it says after 45 minutes of nothing it will sleep.

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 (some of it is hidden by disclosure triangles) 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.
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
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. Click Utilities, then Console in the icon grid.
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.
Step 5
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.

Won't wake up from sleep mode

I have only had my iMac for a couple weeks and four times now it won't wake up from sleep mode. I have to use the on/off button for a response.

Since you have a new machine, I would call Apple immediately and have them deal with the problem.

X1C won't wake up from sleep mode using keyboard

Hi...so finally got my X1C today. One thing I am noticing is that the machine won't wake up from sleep mode when I press any key on the keyboard -- it only wake up by pressing the power key. This is a bit unexpected to me. Is it by design, and is there any way to change this?
Thanks for your help.
Solved!
Go to Solution.

Does it awaken from stand-by if you press the Fn key? That's been the ThinkPad standard for as long as I can remember.
Regards.

MacBook screen goes gray and won't wake up from sleep - 10.6.2

We have a MacBook Alum running 10.6.2 with 4gb ram.
We recently upgraded to 10.6.2 from Leopard and this issue started to happen.
It seems that as the MacBook goes to sleep or goes to the screensaver mode, the screen goes gray and won't wake up from sleep or screensaver mode without a hard reboot.
Is Apple aware of this issue? It did not happen with the previous version of Leopard. This issue arrived when we upgraded to Snow Leopard. Other than the sleep issue, SL is rock solid. Kudos to Apple for producing a great OS!

Hi GrooveDaddy,
Have you contacted AppleCare via telephone to make them aware of this issue? It definitely doesn't sound like normal behavior. What sort of troubleshooting have you done so far on the issue? What sort of settings do you have on your screen saver? Password protected? Custom iPhoto slideshow?
What if you manually sleep the machine by closing the lid or engaging it via software (via the Apple menu) does the screen have the issue in both scenarios?

G3 Bronze Keyboard won't wake up from sleep

I have a hand-me-down Powerbook G3 Lombard 400 Mhz (bronze keyboard), with a dead main battery. It works great with the power adapter, and has just enough charge for me to move it from one outlet to another without shutting down. I'm trying to set it up for use as an Itunes server connected to my home stereo, which is fine because it will always be plugged in.
The problem is that the laptop won't wake up from sleep. This morning I noticed that the display and HD seemed to be sleeping, but the fan/processor buzzing noise was still going (there were no lights other than the little green light on my PCI card). I couldn't figure out any combination of keyboard or power key strokes that would either wake it up or shut it down. I unplugged it, waited half an hour or so, and it finally shut down. I then plugged in, hit power, and it started and booted perfectly (after the expected disk check for abnormal shutdown). Then this afternoon, the whole thing was sleeping (I think -- no sound, no lights other than PCI card light), and again it wouldn't wake up. Again, I unplugged, let it power down (waited for the PCI light do die), the replugged and it started up just fine.
Any idea what gives? Or what I do when it's sleeping? Right now, I have changed the power saving settings so that it never goes to sleep, but I'd really like to let it sleep when people forgot to turn it off...
thanks!

aldpol,
There are many causes for sleep issues and you just have to wade through them one at a time.
You can always force a Lombard or newer powerbook to shut down by pressing/holding the power button until it turns off. As you have noted, this is an undesirable process since you can corrupt the HD.
I would start the troubleshooting in this manner:
1. Unplug all peripherals (PC cards, mouse, everything).
2. Reset the power manager:
http://support.apple.com/kb/HT1431?viewlocale=en_US
3. Now put the powerbook to sleep via the Special menu, wait a minute or so, then wake.
4. If no success, restart while pressing the shift key until you see the message 'extensions off', then release. Now test sleep/wake.
If number #3 is successful, one of you peripherals is probably the troublemaker. If still having issues, please post back with more details if possible.

Gen 4 iPad will wake up from "sleep mode" on its own and stay on till fully discharged, getting fairly hot in the process

Gen 4 iPad will wake up from "sleep mode" on its own and stay on till fully discharged, getting fairly hot in the process

I think I have the same problem. The whole sequence is:
* Put MacBook Pro to sleep by closing lid.
* After some period of time that varies, I notice sleep LED is no longer pulsing.
* The case is VERY hot.
* When I open the lid, the display stays black.
* No sequence of keys or closing/opening lid wakes display.
* Only way to recover is to power cycle.
* Problem is VERY intermittant -- I do not know how to reproduce it at will. AppleCare service had it for a whole week and couldn't reproduce it, whereas for me it occurs once every 1 or 2 days.
Actions:
* AppleCare service replaced the main logic board in early June, but it didn't help.
* I did a clean erase and install, but it didn't help.
* AppleCare service had the unit for a full week in July and couldn't reproduce the problem, so they returned it and it still had the problem.
I have a Logitech Bluetooth mouse, don't know model other than M-RBB93. I'll UNset "Allow Bluetooth to wake..." and will also turn off the bluetooth mouse before closing lid. I'll post my results.
Meanwhile, please let me know if anyone determines a solution!

My early 2008 MacBook won't wake up from sleep

My early 2008 MacBook won't wake up from sleep periodically. I will have to hold the power button down and then restart when it acks up. It did this twice yesterday & once today.

Try resetting the PMU (power management unit).
Remove battery and power adapter.
Hold down power button for 10 seconds.
Reinstall battery and attach power adapter.
Hold down Command-Option-P-R, a total of four keys, and press power button. Don't release the keys.
Continue holding the four keys until you hear the startup sound twice, then release.

MacBook won't "wake" up from sleep, when being folded

I have a MacBook 2.26 GHz Intel Core 2 duo, Snow Leopard 10.6.8.

I've solved my problem.
I have reset my MacBook's PRAM settings.
It's very easy: link: http://support.apple.com/kb/HT1379
Resetting PRAM and NVRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
Your computer's PRAM and the NVRAM are reset to the default values. The clock settings may be reset to a default date on some models.
Hope this helps
Best regards,
Christian

G5 won't wake up from sleep & fans go to high speed ???

G5 won't wake up from sleep & fans will go to high speed within a few minutes of it going to sleep. Whether I put it to sleep or it goes to sleep on it's own per my preferences in energy saver. I have to manually shut it down by holding the power button in. I ran the system hardware dvd and results were good. I have repaired permissions, reset the PRAM.
Any ideas?

"Try Disk Utility
1. Insert the Mac OS X Tiger Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, test sleep in Safe Mode, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

Powerbook won't wake up from sleep, trouble rebooting, kernal panic

Hi,
My powerbook has recently been having some troubles. This started over the weekend and nothing major has changed recently. I added some new RAM months ago, but that was like in June maybe, and it was Samsung module which i think is what that line of powerbooks used originally. The computer had been exhibiting signs of sluggishness and slow operation which i was mostly attributing to a pretty full HD that was in need of some optimazation and maintenance (which i do semi-regularly with Tech Tool Pro).
So, when it goes to sleep, or when the lid gets closed, it won't wake back up. black screen and unresponsive to any keys, though i can still hear the fans and some HD spinning noises inside. So, this forces me to force shutdown by holding the power key until i hear the machine turn off. Then reboot. When re-booting i have been getting a combination of kernal panics and freezes on startup, just hanging with a blue screen and a spinning startup indicator.
I can boot with no problem from an external Firewire drive. So i've run a ful Tech Tool sweep of the machine, optimized the HD and all that. Then, all is well UNTIL it goes to sleep again and then i'm back in the same cycle.
Any thoughts or advice here?

Yeah. I guess i am going to take it in this week. in the meantime though, i wonder if anyone can translate this panic.log entry from another round of kernal panics that i just went through this morning. I had about 4 or 5 of them in a row after trying to reset my PRAM to try and fix an issue with my external isight.
