Screen won't wake up after long sleep. HP Envy All-in-one, no touch screen, windows 8

If asleep for a short time (+ or - 30 mins), it wakes up. For a longer time, the computer comes alive, but the screen stays dark blue. If I wait two minutes and then move the mouse or space bar, the screen comes up.
I worked through the on line help, changed several settings, but it did not help.

ARD 3.3 Will not Wake Machine After Long Sleep

We are using ARD 3.3 on our network. We have found that ARD will not wake machines after they have gone to sleep and stayed in that state overnight. If I manually wake the machine and put it to sleep, it works fine. If I wake the machine and put it to sleep for several hours, it still works fine. The problem is completely random and only seems to happen when the machines have been asleep overnight. There are three machines this occurs with, I will describe each one below. I have a sneaky suspicion that it is our Firewall appliance causing the problem, but would appreciate any other input...
Machine #1
Intel Imac 2.8Ghz core-duo
OS X 10.5.8
4GB 667mhz DDR2 SDRAM
Problem: Occurs 98% of the time and is very consistent on this machine
Machine #2
PPC G5 Imac 1.9Ghz
OS X 10.4.11
1.5GB SDRAM
Problem occurs about once a week to once every other week with this machine
Machine #3
Intel Imac 2Ghz Core Duo
Mac OS X 10.5.8
2GB 1067Mhz DDR3
Problem occurs once in a blue moon
I have tried the following troubleshooting steps with machine #1 because it seems to have the problem so much...
1. Tried another user account
2. Tried removing power management plist located in HD --> Library --> Preferences --> Systemconfig
3. Tried resetting the SMU
4. Tried to repair disk permissions
5. Ran FSCK -FY from single user mode
6. Ran AHT for 17 hours straight with no errors
7. Booted to clean install of OS on external FW drive with user ported to FW drive.
BTW: Our firewall appliance is an Snapgear SG560 with the latest firmware.
Thanks for any input much appreciated...

I cannot wake up any computers even if asleep for a few seconds. ARD 3.3 has broken a lot of features such as copying files by dragging from a remote connection to desktop and it no longer reports Current Status correctly.
AWFUL update. Apple please fix this or explain how to downgrade to 3.2
I can no longer use this in the school where I supervise 50 Macs.

ThinkPad S230u won't wake up after IRST sleep since BIOS update

I am using S230u (i7 CPU, 8GB RAM, 500GB HDD+24GB SSD) with Windows 8 x64 for half a year now and so far everything has worked just fine.
I have IRST enabled and when I put it in sleep mode, it automatically saves the state to SSD after an hour. That has worked great so far - I can put it to sleep for short periods and get it up instantly and if I put it to sleep for longer it will save to SSD and not use battery - when I wake it up, it flashes the red LED for a while and system comes back online.
However, this Friday I installed BIOS update - updated from 1.57.1.57 to 1.61.1.61 (at least according to System Update history).
Since Friday when I try to wake it up it does not work if the sleep is longer than an hour (or so) and the state was stored to SSD. The red led keeps flashing, but nothing happens - after around 1-2 minutes the system reboots and Windows loads again.
I want to downgrade the BIOS and doublecheck that this is the issue - perhaps it is some other Windows or Lenovo patch, so I want to be sure.
I have already located the BIOS drivers downloads (http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS032000) and am wondering if downgrading BIOS to check if this is the issue can break anything with my laptop?
Solved!
Go to Solution.

We are working on the BIOS defect that causes this failure. I'm very sorry for this inconvenience.
While downgrading the BIOS is a possible work-around, my advice is to simply disable the 30-Day standby feature in Lenovo Settings, until the new BIOS to fix this issue is released.

IMac (Mid 2011) Does not wake up after long sleep

Hi People,
Having issues with my Mid2011 iMac (21,5", 2.7GHz). Just upgraded to 12GB RAM (2x2GB original + 2x4GB). System runs fine, no issues.
But when system goes to sleep for a longer period (a few hours) it will not wake up again. Neither by Keyboard/Mouse interaction (Bluetooth as well as USB) nor by pushing the powerbutton. I also performed the PRAM and SMC reset as described in the apple support resources.
Feeling a bit lost. Any Ideas?
Thanks in advance for any help!

Addition:
Performed a test of the RAM with memtest. No erros found. Also forget to mention that the Mac has also Software updates and firmware updates installed.

IPad 2 won't wake up after auto sleep or pressing sleep button!! Help

Hi all,
Actually sometimes iPad 2 is not waking up after I press sleep button or it goes to sleep after some time. And I need to restart using home and sleep button.
The problem that this doesn't happen always. I faced it few times ! Anybody has any idea if this is software or hardware issue ? The problem also that I can't take it to the apple shop because the problem is not continuous and it is not always visible please help !!!!
BR,
Hani

Something may be hanging up. Do a hard reboot:
Hold the power and home button for at least 10 seconds (hold past the swipe to shut down) until the Apple logo appears, then let go of both buttons and your iPad will reboot. You won't lose any data or settings.........

Mac pro won't wake up after installing Mountain Lion

After installing Mountain Lion in my Mac Pro it won't wake up after long periods of sleep. I have tried unplugging it for 15 seconds and plugging it back in and starting it back up. No help. I've reset the Pram with no change.
Chuck

Two calls into tech support, but I think they may have helped me fix this.
CHECK:
\Library\LaunchAgents
\Library\LaunchDaemons
\Library\StartupItems
remove any third party software and set aside. (they told me I could keep some adobe, microsoft and HP items)
THEN CHECK:
System Preferences --> Users + Groups -->Login Items
remove any third party stuff from in there.
I'll know tomorrow morning if this REALLY works, but it dfefinitely allowed my computer to sleep and wakeup over a short period of time.

1G iTouch won't wake up after sleep

1G iTouch won't wake up after sleep. When I plug it back into my laptop it does a complete reboot. Tried both reset and restore. Works fine as long as plugged in. It shows a full battery and drains properly but once it goes to sleep it acts like battery is fully discharged.

Is the iPod or the laptop going to sleep?
I can't tell for sure from your post.
When you restored, was it "as a new iPod" or from a backup?
What software is on the Touch?

Memory RAM upgrade won't wake up after sleep mode

i just recently purchase a pair 16GB RAM of crucial CT2K8G3S160BM for newegg.com. Yeesterday i try put this on my macbook i7 intel 2.9 processor that crucial said is compatible. but found out everything was good until i close my mac lid for hibernate. What happen is, it won't wake up no matter what i do until a way of reset SMC. BTW i try stick by stick to plug in together with my original 4gb RAM together found out 1 was ok and other one was not. But somehow why the info of hardware show that memory ram 16GB was installed and was OK. Everything was run smooth even booting. The only problem is won't wake up after sleep mode. I already try reset smc, pram, delete startimage, delete powermanagement.file and also sudo hibernate 0-7. Did anyone had this same issue of me. I'm my curiousity will it be the bad ram or software problem.

i just google around and found this two both crucial ram. Both spec are the same but different model no.
CT102464BF160B 16GB and mine is CT2K8G3S160BM are this 2 same? but both same spec.

Macbook Air 2011 won't wake up after sleep

My Macbook Air 13" 2011 won't wake up after sleep. I've taken it to apple genies bar, but they offered to replace my logical board!
I bought the Macbook Air in last August. Why cannot they replace a new laptop???

One thing you want to do is "Repair Permissions" in Disk Utility before you upgrade to a new revision, and afterward do the same thing.
On occasion files will become inaccessible to the logged-in user and cause certain components of the OS from acting cooperatively. This can most often happen during/after an update. Also, by resetting permissions before an update, it is to ensure that the update process itself can accomplish all tasks.
You may also want to consider applying/re-applying the downloaded 10.7.3 "Combo Update" from the Apple.com/downloads/ section. After resetting permissions, of course.

ThinkPad T420i won't wake up after going to sleep.

My T420i won't wake up after going to sleep (using Fn F4 or close the laptop or time out). The computer was wiped clean and reinstalled with only Windows 7 professional and some Levono softwares. BIOS, windows and all drivers are up to date. The only way to get it back is hold the power button to reboot it. When it reboots, i get improperly windows shut down error.

I'd guess it's ACPI related issue. Check out ACPI driver and correspondent items in Control panel.
Energy report might be helpful too ("powercfg -energy" command within console window with administrator rights)

My Macbook pro, (late 2010) sometimes will sleep and won't wake up. then the sleep light flashes.What's the problem?

My Macbook pro, (late 2010) sometimes will sleep and won't wake up. then the sleep light flashes.What's the problem

Hi I've been following this thread (along with a different one on the same topic). I've been having the same problem with my ibook. I can add that I have no problem with startup. It's just that the screen "goes to sleep" unexpectedly and may operate normally for a few minutes or a few hours at most. Opening and closing the lid or restarting seems to cause it to awaken but then usually for just a few seconds or minutes. If it is connected to another video display that display continues functioning fine even though the computer screen is blank. In addition the desktop is there and visible faintly or if totally blank can be backlit through the apple logo and can be read. I've had my logic board replaced twice under the extended warranty and assumed it was that but now I'm thinking of the reed switch. Apple refuses to consider any further work under warranty as the last repair was in Jan, 06 and they claim only a 90 parts warranty and the machine is from 03. Any thoughts before I cut the wires? I have reset the pmu, run cocktail and disk utility. Other than the sleep issue the machine works fine. thanks Ronda or anyone else who has any ideas... Dave

Laptop won't wake up after closing lid

The laptop won't wake up after closing the lid. It hasn't happened before. There have been no updates or changes for a day or two. The power button light and the fan are on, the caps lock key is flashing, and the wireless light is orange instead of white, like it is when powered up. I have tried ctrl-alt-del, every fn key, the esc key, the pause key, and every comination of keys that made any sense and many that didn't. I tried disconnecting the power, removing the battery and holding the power button for 30 seconds. I tried leaving the battery out while disconnected from power for 24 hours. I have looked at different forums for clues, but haven't found any help.
My next step will be to remove the hard drive to get the data, so any help would be GREATLY appreciated.

HI @tootall69
Thank you for your reply.
You can try this step as it will restore the power schemes back to the defaults.
Here is a link to Troubleshooting sleep and hibernate issues (Windows 7) that may help.
Next you can try this.
Go to start run
Type command prompt
Right click on it and run as administrator
Type powercfg -restoredefaultschemes and press enter.
You could also do a restore to before this started to happen. HP Notebook PCs - Using Microsoft System Restore
The next step would be to do a recovery back to factory.
Performing an HP system recovery (Windows 7)
During the recovery you will notice the option to backup your personal files to prevent data loss. If you have not already done one, now is a good time.

X301 in Coma, Won't Wake Up from Natural Sleep or FnF4

X 301 SSD 64g won't wake up after naturally goes to sleep, or when put into sleep FnF4. Must remove power cable and battery to break power and restart. When in coma, extremely brief flashing of hard drive access, also Power white center light lit, Think Vantage blue bar lit, and speaker off light can be lit when toggled.
All ideas, similar reports appreciated. tnx.

I have this issue on a number of different Lenovo models (T500 and X200 seem the most common). In analyzing the issue we have not found a smoking gun to this issue either and done an extensive amount of troubleshooting (BIOS, Drivers, power management config etc).
That said, have had some success at removing TVSU from the machines, we began seeing this issue once TVSU was deployed to the environment. We do run a 3rd party power management interface but that doesn't appear to be at issue; even when it is removed entirely the issue persists.
This issue is really difficult to troubleshoot as it's very vague and inconsistent so replication of it has proven nearly impossible. Just thought I would add my 2 cents guys, cheers.

My mac won't wake up from a sleep and I have to unplug it to reboot as the power button doesn't function as well. Any suggestions? Running Lion 10.7.4 and sending all reports in.

Do the SMC RESET and do the PRAM reset.

Aluminum Keyboard won't wake Mac mini from sleep (sometimes)

I just bought the new aluminum keyboard (wired). Its great, and looks amazing next to my mac mini......except it won't wake mac mini from sleep sometimes. When this occurs, I can tap on any key but the machine won't wake up. The only work around I have is to attach my ipod, which wakes the mini. Oddly this only happens sometimes. I can't isolate any other variable which may be influencing this behavior.
I'm running leopard and didn't think I needed to install the 1.2 keyboard software update.
I called Apple support, and they told me the problem is that I'm using a non-apple mouse (I have a microsoft optical wired mouse connected to the keyboard's USB port). I don't believe them as i've used this mouse connected to my previous Apple keyboard for years and never had a problem.
Can anyone help?

Regrettably, I can't offer a solution to the problem stated in the title. Instead, I experience the same problem.
Wireless Mighty Mouse circa 2007
Wireless Apple Keyboard circa 2007
Bluetooth dongle (a bluetooth thingy connected to a USB port)
Things worked fine until an upgrade from Tiger to Snow Leopard. Following the upgrade there were several mouse related issues. Those were resolved. One issue remains: waking by use of mouse or keyboard.
The setup (Same for keyboard and mouse)
System Preferences --- Bluetooth --- Keyboard Connected --- Keyboard Paired. The "Discoverable" box is checked.
Digging deeper
System Preferences --- Bluetooth --- Advanced --- "Allow Bluetooth device to wake this computer" --- This option is unchecked and is greyed out, inaccessible. Two of the other options are checked and available: the options about opening the Bluetooth assistant and the one about prompting incoming audio.
I've searched other posts. However, many of the other posts seem to conflate this Wake/Sleep issue with various connection issues. Thus, the advice given is a bit confusing to this amateur. Might one of you experts have a solution to this annoying little problem?
Thanks for your interest.
