Windows 10 - won't enter sleep mode

So I updated to windows 10 roughly a week ago. I have had sleep issues from day one with it not being able to wake up if it didn't enter sleep mode properly. I ended up just remembering to hit the power button or shut the lid and that was enough to put it into sleep mode and was able to wake it after opening. I saw another user said to update the Bios driver... that was working til a windows update. Two/Three days ago windows had an automatic update and that seemed to cause the problem again. But now I cannot get it into sleep mode at all even with the power button, closing the lid and even going to start and hitting sleep. it turns off the screen and the power light continues to just be on without blinking and the fan keeps running. This computer is only 6 months ago and I am getting frusterated. I will probably go back to 8.1 as having to hard power down the computer can't be good for it everytime I walk away and forget to completely power it down. Does anyone have another solution I can try before I jump ship?

I have installed all updates from Windows Update and all drivers from Toshiba US website. I can't find the Service Station for Windows 10 from Toshiba website. I only found the one for Windows 8.

Mac Pro unexpectedly enters sleep mode

Ok so I installed Leopard last weekend on my Mac Pro and all initially went well with the install. After installation was done, software update appeared and stated I had approximately 4 downloads to install. So I had done this and prepared to reboot. Before rebooting, a window appeared stating that it needed to update the Boot cache. So I clicked on "OK" and the computer went into its shutdown sequence. When the computer reset, I noticed there was no start up chime and the system just sat there with a black screen. I thought perhaps it was updating the boot cache and it may take a while to finish. So I went afk for about an hour and came back. Still nothing. This is when I knew there was something seriously wrong with my system.
After speaking with Apple support and trying several things to get it to boot, the support rep stated that it will need to go into the shop for repairs. I had taken it to an authorized service center and they diagnosed the problem as a bad logic board. They had replaced this and had ran their diagnostic tools on it to make sure it was running normally. They kept it overnight and ran Apple Service diagnostics in a repeating loop on the system. They had also cold booted the system 30+ times per the work order.
After I brought it home and booted it, everything was seemingly running fine. Then I received a page from work (I'm a support rep) which required me to boot into Windows using Boot Camp to solve a client's problem. After I had done this, I booted Leopard back up and was playing around in it for a few minutes to check out some of the new features. I had then ran World of Warcraft to play a bit and to check out the performance increase in Leopard. After about 5 minutes of playing, my system unexpectedly entered sleep mode. Obviously I was confused so I had brought it out of sleep mode by hitting the enter key. The system came back for about 2 seconds and immediately went back into sleep mode again. This happened about 4 or 5 times before I finally shut the system down.
The first thing I did after reboot is to check the energy saver options. Both hard drive and monitor energy options were set to "Never". I then checked for software updates. There was both an SMC firmware update and a Boot Camp EFI(?) firmware update. I had done the SMC firmware update first and then after successfully updating this, I had done the Boot Camp firmware update. After reboot, the system went into sleep mode on its own approximately 5 minutes after reboot. This time I had made sure NOT to run my game as I had a suspicion that this could be causing the problem. It entered sleep mode anyway unexpectedly. After waking it up again by hitting the enter key, the desktop appeared again for about 2 seconds before going right back into sleep mode. I called the service center again and they said I would have to bring it in for them to look at. Needless to say, I am NOT very pleased.
Has anyone ever heard of anything like this happening with a Mac Pro? I had never had any problems when I was running Tiger with any application, not even my game. The service rep where I took it said it was just bad timing that the logic board went during my OS upgrade and that the two had nothing to do with each other. My brother has a Mac Pro as well and he had upgraded to Leopard. Of course his computer works fine where mine is a sleeping fool. Does anyone have any ideas or theories as to what could be causing this? More importantly, does anyone have any suggestions on how I might be able to fix this on my own? If you could please let me know, I would appreciate it. Thank you in advance for your time.

Wow, who are you dealing with? The first time my logic board was replaced, the techs never bothered with looking at anything else as being the problem. However, when I pointed out the power supply fan problem, they focused on that being the cause of the problem and fixed just that. I was somewhat concerned as I know some of these techs do not look at other parts of the machine as potential problem causers. I was afraid that I would hook up my system only to experience the same problem as before. Luckily, that was not the case.
I am glad that your system appears to have the same problem as mine did. I would suggest that if you take it back to them again for a fan fix to have them run the system for about an hour after replacing it. They should be opening apps, checking the iStat widget, etc to try and make it break. If they can't after an hour or so, I think it should be ok.
This whole ordeal makes me question the quality of parts used by Apple. My brother has an iMac G4 where the hard drive died after 2 months of getting it new. Now this issue with mine and yours with the bad logic board and the power supply fan. Who knows how many other customers report hardware related problems?

Mac mini keeps entering sleep mode

Hi. I have a Mac mini that has this annoying problem where it keeps
wanting to enter sleep mode. This problem seemed intermittent at first.
What I notice is that my mini would enter sleep mode whenever I try to
encode mp3. This seems reproducible. When it enters sleep mode,
I can wake it up by pressing the power button. However, it goes back
in sleep mode after a couple seconds after it wakes up. The only way
I can get it out of sleep mode is to quit iTunes and eject the audio
CD.
Things I've tried:
Energy Saver settings: Computer sleeps after 3 hours inactivity,
display sleeps after 3 hours inactivity, unchecked "Put hard disk(s)
to sleep when possible". I tried disabling energy save. No luck.
I also tried to uncheck "Allow Nap" box in the Processor settings.
However, it always checks this after a reboot.
If I insert a DVD movie, I can watch it w/o any interruption.
Anyone else seen this problem? Thanks in advance.

Hi Carl. I was unable to find com.apple.AutoWake.plist in my
system. Deleting com.apple.PowerManagement.plist didn't
help.
I decided to try your open firmware instructions. I like the
boot loader. It reminds me of the Sun's boot monitor.
I did the reset-nvram, set-defaults, reset-all. It didn't
help though.
I don't think it is my power supply, either. The reason why I
don't think this is the problem is I can watch DVD and listen
to audio CD just fine. My sleep problem would only occur
when I try to rip an audio CD. I can assure you that I draw
plenty of power just playing a DVD movie.
My guess is I have a power management configuration
issue or a hardware problem. Since this has a Unix core
underneath, I started poking around in the usual places
for log files. I found the familiar /var/log and stumbled
on system.log. Looking at the file, I found something
that caught my eye.
Aug 17 01:06:19 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Doing a 'grep overtemp system.log', I got the following:
Aug 17 01:04:13 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:04:37 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:04:56 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:05:37 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:05:51 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:06:00 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:06:13 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
Aug 17 01:06:19 Jim-Fridlunds-Computer kernel[0]: Power Management received emergency overtemp signal. Going to sleep.
If you look at the time stamp, you'll see that each event
is only a few seconds apart. This matches with what
I was seeing. Machine goes to sleep. I press the power
button and it wakes up and goes back to sleep. One
big endless cycle. The only way I managed to get out
of it is to quit iTunes and to eject the CD.
Yes, I did install the Xcode 2 development kit that came
with the Mini MAC OSX setup. I eventually want to write
software for the Mac. So, I most likely installed the
CHUD tools package that you had mentioned.
I think the equivalent command line command for
disabling the nap feature is 'hwprefs -v cpu_nap=false'.
When I do that, I get the overtemp event and my mini
goes to sleep. Zzz.
In any case, my mini seems to be detecting false overtemp
condition. Either I have a bad temp sensor or my power
management overtemp threshold is set way too low. It's
possible encoding audio CDs is enough to heat up the
PPC core, but it happens way too fast. I'm thinking my
temperature sensors are not set correctly. If anyone has
schematics for the mini, it would most likely be a Dallas
temp sensor chip. I'm not ready to open up my mini yet
since it is still under warranty. I'll take it in the Apple
store in Walnut Creek this weekend.
Anyway, thank you guys for all your help. I found my
experience on this forum to be quite pleasant. People
here are very helpful.

Lenovo thinkpad 8 not entering sleep mode when lid closed

RECENTLY I BOUGHT THINKPAD 8. I HAVE A PROBLEM. IT CAN'T ENTER SLEEP MODE. I CLOSE THE LID AND THE SCREEN IS ON. AT POWER OPTION IT IS SELECTED WHEN I CLOSE THE LID TO GO TO SLEEP , ON BATTERY AND WHEN PLUGED IN. THANKS FOR ANY HELP.
Solved!
Go to Solution.

I am not certain what you mean. Are you saying that when you close the cover it does not sleep? Are you certain you have a cover with the magnets that will put it to sleep?

My macbook pro 2.0 early 2011 will not go to sleep with the power source connected. only enters sleep mode when running on battery. Someone did this happen, and it could solve?

Alo, my Macbook pro i7 2 GHz Intel Core i7 (early 2011) will not go to sleep with the power source connected. only enters sleep mode when running on battery. Someone did this happen, and it could solve?

There is no output from that command line? Maybe the pid changed.
I'll repeat what I am trying to find out...
1. You do a pmset -g on the terminal.
2. The output from that pmset should have a line that says "sleep 0 (imposed by n)" where n is some number.
3. The ps ax | grep n is supposed to display what the process associated with n is.
It's the output from step 3 that should indicate what is causing you not to sleep.
But speaking of sleep, that's where I am going.

Computer enters sleep mode shortly after leaving sleep mode. Defect?

I have a problem. It's not a serious problem, but since it seems to be hardware related it might cause problem in the future.
It's pretty simple. Let's say I fold the computer screen down and leave the computer in sleep mode. If I then fold it up again it will automatically enter sleep mode once again 25-30 seconds after waking up. It doesn't matter what I do. I can be completely passive or open any app and move the cursor as much as I like. After roughly 30 seconds the screen turns black and I have to press a key to wake it up.
It never enters sleep mode any other time if I don't choose so, it's always after being in sleep mode already. And it happens 80-90% of the time, but I have not noticed a pattern for when it doesn't.
Naturally my settings are in order. I just updated it today and no difference after one attempt with the new OS version.
Any ideas?

Sleep.
Shutting down a Mac is never required. It is best to let it sleep, unless you are planning to not use it for a period of time considerably longer than a few days.

Home Sharing turns off as soon as my computer enters sleep mode. How can I work around this issue?

MacBook starts and instantly enters sleep mode

In the past few days I've been experiencing a reoccurring problem with my macbook pro. I press the power button, hear the startup of the drive, and then sometimes the display will turn on for a second(mostly stays off), and then enters sleep mode instantly. I can not get on my macbook unless I turn it on and let it sit for 15-20 minutes, then MAYBE the display will activate. Please help.

Do you hear a chime at startup? How do you know it is entering sleep mode and not turning off? Does the cursor move on the screen? Here is something from another user's experience:
I had the same issue with my 2008 iMac and Apple support walked me through the fix yesterday...
1. Shut the computer down by holding the power button for 10 seconds
2. Restart the computer and press shift at the same time until you see the progress bar start moving
3. Once you reach the point where your screen goes dark and you see the cursor, type the first letter of the username for your computer, then hit Enter, then type your password, then hit Enter.
4. After a moment, you should see the spinning beach ball
5. Your screen should then move on to something along the lines of "Completing OSX Installation" (I can't remember the exact wording). Let it finish. After that it should go to your normal desktop and the issue should be fixed. (If your screen goes pitch black during this process, hit the space bar. I thought it wasn't working, but the screen was just sleeping).
Apparently it's an issue with an automatic update that never quite got past the login screen.

IMac beeps once before entering sleep mode

My iMac 24 inch has started to beep once before entereing sleep mode. The LED thinks blinks whilst it is asleep, which I assume is normal. Is this indicative of a hardware fault? I understand that a single beep on startup indicates a ram problem.

If you listen carefully, you may find this beep is
coming from the hard drive, not the speakers (plug
headphones in and find out if it still makes the
beep).
Some hard drives make this beep if they have a
re-positioned write, which is a non-fatal error. You
can usually reformat to re-allocate the block and
stop the error, or you can live with it.//
Hi
Yes you're correct, it doesn't come from speakers. It not makes the same faint beep (rather like a heart monitor blip) when closing down and always after the screen has gone blank. I have noticed that if you put a CD-ROM in the DVD drive and its still spinning when you put it into sleep mode you don't get the sound.

T530 wakes up immediately after it entered sleep mode or hibernation mode.

My brand new T530 comes with windows8, but I found a strange thing that it can 't enter sleep mode or hibernation mode, every time it will wake up immediately even I close the lid. The battery will be ran out in several hours.
Anybody has same problem?

Attempt to enter sleep or hibernation, then when it wakes up right after, go to Command Prompt and run "powercfg -lastwake". It'll tell you what woke up the system.

My iPod touch shuts down instead of entering sleep mode.

Like a good little user, when iTunes tald me I needed to update the software on my iPod I did so. Since then whenever it should be entering sleep mode it shuts down entirely. Not only is this monumentally annoying because I constantly have to reboot the thing, but it causes the battery to run down faster. I've been looking through the settings trying to see if a default somewhere has been set in an odd fashion, but so far nothing. I ducked into an apple store on my lunch break and they suggested going for the system restore, but that will be a pain and will delect everything on there. Can anyone suggest a way to fix this problem? Have any of you seen this before?

All ther is is the standard fixes:
- Reset:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory defaults/new iPod.

All-in-one 6830 printer Does not enter sleep mode when connected to a phone line

HP staff help. HP all-in-one printer 6830 does not enter sleep mode when conntected to a phone line via 1-Line jack. The Firmware is PNP1CN1521AR. On August 1, 2015, I purchased an HP all-in-one 6830 printer and upgraded to firmware PNP1CN1521AR.When a phone line is connected to 1-Line jack of 6830, the printer will no longer enter sleep mode and the display remains on indefinitly.Removing the phone connection either from the wall outlet or from the printer causes the sleep mode to work correctly again where the control panel display turns off after 5 minutes (or optionally after 10 or 15 minutes).This problem was previously reported by a user and has not been resolved, see:http://h30434.www3.hp.com/t5/Other-Printing-Questions/Sleep-mode-of-Officejet-Pro-6830/td-p/4772182 The user did not receive a resolution to this problem according to the thread.
There seems to be a 6830 printer firmware or hardware problem causing this. HP should be able to confirm this problem on 6830 easily.
Please advise ASAP.
Thanks

It's a regular analog phone line. I've tested it with other phone lines. No difference. I have another all-in-one printer which works fine (goes to sleep mode) when plugged into the same phone line.
The 6830 works ok in other aspects. The only problem is the sleep mode. Any 6830 with the firmware I mentioned should replicate the same result, regardless of anything else. The previous firmware to PNP1CN1521AR also created this problem according to the original report of this problem by another user.
I'm sure there's a bug in the firmware. A subroutine in the firmware monitoring the incoming fax ringing, mistakenly, sees the voltage across the phone jack pins as an event and wakes up the printer instantly even though there's no ringing. As the previous user also suspected, there seems to be an error in the phone line voltage threshold used by the firmware. The present firmware always sees a ringing at the phone line which causes it to never stay in sleep mode.

OSX Lion iMac fails to enter sleep mode.

Hello
My 2010 iMac fails to automatically enter sleep mode after upgrade to OSX Lion.
There is no problem using the keyboard shortcut or the sleep command in the menu.
However, it´s driving me crazy that it does do it by itself.
The energy saving options are set correct (enter sleep mode after 10 minutes).
I have tried to reset PRAM as well as SMC.
Internet sharing is turned off.
Any ideas......?

I have the same problem - late 2009 iMac, will not sleep after set period of inactivity. I have tried many things, including SMC and PRAM reset, 10.7.1 update, disabling Little Snitch, GlimmerBlocker, etc. etc., even removing Wacom tablet drivers and Flip4Mac, and disabling websharing (Apache), and switching internet sharing on and then off again. No difference. The only benefit is that I have learned I can sleep my Mac by pressing and holding the play button on the remote...
One thing I have noticed though is that I can hear disk activity when under 10.6 I would not expect it. Maybe something is accessing the disk and that is keeping my Mac from sleeping.

Why is there a clicking sound when I close the cover and enter sleep mode?

why is there a clicking sound when I close the cover and enter sleep mode?

Hi katesvca,
I too have an iPad smart cover, and all that clicking sound is is basically the standard lock sound for iOS. The Smart cover is equipped with magnets inside, and the iPad is also equipped with magnets, and when those magnets are closed together the iPad goes to sleep.
I hope this answers your question.
