Windows 8.1 won't wake up from sleep

I seem to have the same problem that many have already expressed, the difference is that my laptop (HP ENVY) just started sleeping in, permanently and not waking up. I prefer to have my computer sleep, rather than hibernate (although I'm not clear as to
the difference in the two states), and would like to have it return to "obedient" mode and comply with my every command, in this case "sleep" when I close the cover, and "wake" when I return and open the cover.
Any ideas of how to accomplish this?

Hi,
"in this case "sleep" when I close the cover, and "wake" when I return and open the cover."
Did you try to wake your computer by pressing any key on the keyboard, clicking a mouse button, please lauch Device Manager, find your mouse and keyboard deivces, right click\Properties, then under "Power Management" option, check the
"Allow this device to wake the computer box"
And check the "Power Management" option of the "Universal Serial Bus controllers" in device manager, Uncheck "Allow the computer to turn off this device to save power".

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.

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.

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

When I "fold" computer it goes to sleep. But, when I flip up the screen again, my Mac won't "wake" up from sleep mode anymore.
Do anyone know how to fix this problem?

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.)

Windows 10 updated now HP Pavilion won't wake up from sleep

Since I upgraded to W10 this week, my laptop now will not wake up from sleep. I've searched around on the net and so far can only find people having problems putting their laptop to sleep. I did follow the advice from one of those on the HP forum, to upgrade a driver, which I figured couldn't hurt. It made no difference though. When I come to wake my computer up, which always was by just lifting the lid, now nothing. The power light will glow solid and the wifi light glows orange (as opposed to its usual white solid when machine is running). Other than that, noting. No button pressing or screen tapping of any kind will bring it to life and the only solution is to press and hold the power button to force full shutdown and start again. May be only 3 days into it but it's already driving me mad. Any suggestions welcome!ThanksJulie

Hmmm... I'm on the fence on that one as the software update is Microsoft's so the logical consumer in me says that it shouldn't be HP's responsibility to create the fix. I understand your frustration but from the legal perspective under the UK consumer law, I think HP may well be within their rights to deflect the liability to Microsoft - but that's a terrible example of customer service, after all you've got an HP machine...... BUT (devil's advocate here) HP haven't released the software update or prompted consumers to install it.... so from their point of view, they can probably quite rightly and fairly bury their heads in the sand. The warranty you will have for your machine probably will exclude software issues for anything other than factory installation or possibly HP's own updates. (that's me speaking as a former Trading Standards Officer, so not without a bit of knowledge on the matter...)
That said.............. I did follow the fix that was posted earlier and so far it's looking good. I've left my machine for over 2 hours and it sprung back into life every time today since I followed the BIOS update suggested.
I'm sorry to hear that you've had a bad response from HP "Customer Service" but nothing to stop you complaining about that..!! I'm a great fan of going straight to the top and Andy appears to be the current MD for HP. Whether or not they accept responsibilty for the issues we're all having, they still should be offering a higher standard of response and customer service than that - whoever's "fault" the problems are, they're certainly not the consumer's.

I got an A730 LEMON. won't wake up from sleep

Day one with my new A730
For almost $1600 I shouldn't have to
a)hold the power button down to turn off a brand new computer when I can't get it to wake up from sleep mode on day 1 of use.
b) make 3 calls to tech support to find out whay a) happens
c) have tech support tell me "you don't have any drivers for your screen"
d) have tech support tell me I to reinstall windows
e) have tech support make my computer worse off than before I let them tinker with it remotely
f) have to wait until tomorrow to get speak with someone empowered to send a replacement (it was only 8:30 at night)
what the heck, Lenovo? I bought this top of the line machine to be ready to go, not need 3 hours of my time trying to debug it. I BETTER not hear "as soon as we receive your machine back in the mail we'll ship out a replacement" and I sure better not hear "we'll send you a refurbished machine"

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

Leopard won't wake monitor from sleep on Power Mac G4

I had no problems with my Power Mac dual G4 867 while running Tiger, but immediately after a clean install of Leopard (a fresh install - no third party apps) my Dell 17 inch LCD monitor will not wake from sleep.
The monitor comes on just fine when the computer first boots, but if the computer sleeps, and I wake it by hitting a key on the keyboard, the drives spin up and I can hear that it thinks it's working just fine, but the monitor won't wake.
I know that the computer is working fine despite the sleeping monitor because I can hear VoiceOver working after a clean install of Leopard (if I let it sleep after the Welcome movie) while asking for user information.
I reinstalled Tiger, and the problem disappeared. The monitor wakes reliably from sleep with a fresh, clean install of Tiger. But with Leopard, even turning off and on or unplugging the monitor doesn't wake the screen.
I have reset the PRAM, the PMU, and the Open Firmware (the firmware is up to date). I even opened the case and pulled and re-seated the video card. Nothing seems to work, so I have just set the computer to never sleep. Not a great option, given the insane fan volume in the G4 MDD model.
Thanks for any suggestions anyone can offer.

I'm having similar problems with both a new MacBook Pro and a new Mac Mini, both connected via a Gefen DVI switch to a Dell 2005FPW monitor. Putting the MacBook Pro to sleep while in dual monitor mode will crash the machine. Putting the Mac Mini to sleep won't crash it, but the monitor won't wake—the computer wakes, but the monitor stays black. I can use Screen Sharing to connect to the Mac Mini and restart it (the only fix, as far as I can tell).
I suspect this is a software issue, because my old PPC Mac Mini would usually wake from sleep. The Gefen support people say this shouldn't be happening.
Anyone having this problem should probably post it as a bug at Apple's Feedback page. I think reinstalled, resetting PRAM etc. is probably a waste of time. Meanwhile, don't sleep your monitor.
