Laptop dies during sleep

My MacBook Pro usually could be returned back to life if the battery flattened out during sleep, with everything as it was; running applications and open documents.
Then recently I had to reinstall the system and ever since this function is absent. Now, if the battery gets flat during sleep, it leads to a certain death. Meaning that the machine has to be restarted and all applications that were running have lost what had not been saved. I have looked for a system dialog where this setting is operated, but no luck. Anybody got a tip?

After a bit of research I have learned that the issue is "Safe Sleep". For some reason this default function is missing after reinstalling the system. There is nowhere mention (where I have looked) of how to turn this on or off. ??

Mac Mini Intel Snow leopard often dies during sleep. What to do next?

During sleep the screen goes blank on a light grey color and I can only shut down using the power button. I am using an apple blue tooth keyboard and a logitech USB remote mouse. I have run Disk Repair w Utilities and also the MUG has tried Disk Warrior but problem persists. The Mac Mini is about 3 years old. It occasionally also crashes in Safari or Word. Please advise. Am worried about losing files, but so far so good.

I assume you have a current backup, so I would start by erasing the drive and reinstalling OS X.
Drive Preparation
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Upon completion quit DU and return to the installer. Install OS X. When completed you can restore your data from the backup.

My laptop goes to sleep during the Time Capsule backup process and never finished. What can I do?

I have an older MacBook laptop that I want to backup on my new 2TB Time Capsule. I have set everything up just fine (apparently) and the backup process starts out fine. About an hour or so into the backup process, my laptop goes to sleep. The laptop is plugged into AC power so it is not a battery loss. I have set 'hot corners' so that my screen saver is disabled. Nothing seems to keep the laptop running until the Time Machine process completes. Any guidance appreciated. Thanks!

You don't indicate what operating system the MacBook is using, but in general try the following:
Open System Preferences (gear icon on the dock)
Open Energy Saver
Adjust Computer Sleep to read Never
Adjust Screen Saver to read Never
Run the backup
When the backup is done, change the Energy Saver settings back to normal

Windows 8.1 Pro laptop won't sleep after unattended WSE2012 backup session

Hello,
I have a new Windows 8.1 Laptop, a Puget Computer V560i laptop using a Clevo W350STQ motherboard. The laptop is part of a Windows Server Essentials 2012 domain. I have the latest BIOS and drivers installed, including graphics drivers. Windows
8.1 Pro was installed native (not an upgrade).
The WSE2012 server wakes the sleeping laptop every night between 4 and 5 AM to perform a client backup. This works fine. The problem is that the laptop does not go back to sleep.
The laptop is normally connected to power and sleeps every night---so the server can wake it up. The laptop is set to go to sleep in 30 minutes via Control Panel | Power Options | Balanced | Plugged In.
If I test the laptop during a normal session and don't interact with it, the laptop goes to sleep in 30 minutes fine. Asking the laptop to sleep manually also always works fine.
Note that other client machines on the domain go back to sleep after backup.
I exposed the "System unattended sleep timeout" setting by updating the registry. This timer is set to 2 minutes for ac and dc, the default (as expected).
After a WSE2012 backup via WOL, the laptop does not go back to sleep. I can always manually put the laptop to sleep. This morning, at 9 AM I tried various things:
From cmd (admin), tried powercfg -requests to see if anything was blocking sleep. Nothing was blocking. I expected this given I can manually put the laptop to sleep.
Examined the event log to see if any events indicated blocked sleep. No events present.
Tried to see if the system would go back to sleep on it's own after manual user intervention. It would not sleep this way.
Manually slept the system, woke it, and then tried to see if the system would go back to sleep on it's own. It would not.
Rebooted the system and then tried to see if the system would go back to sleep on it's own. It slept this time.
So, my working theory is that a WOL session somehow blocks unattended sleep until the next reboot.
For a while, if the laptop had not gone to sleep on it's own since the last reboot, it would sleep after the server backup. If the laptop had gone to sleep at least once on it's own since the last reboot, it would not sleep after server backup.
This behavior has changed---the laptop now never goes back to sleep after server backup. It will go to sleep on it's own during a normal user session.
Does anyone have any ideas on how to get the laptop to go back to sleep after an unattended server backup session?
Thanks.

Battery Drainage During Sleep

I saw a few posts on this issue but haven't seen anything in a while. My battery drains too quickly during sleep mode. Has apple addressed this yet. If not has anyone found a fix for it. It's really the only thing that has bugged me about this new laptop.
Any help would be appreciated.
Cheers

No official fix for now.
You have to manage the sleep yourself! If it's a short sleep, just close the lid as usual and forget your 2% comsumption. If it's a long sleep (a hibernation), use something like deepsleep (http://deepsleep.free.fr/) and be patient during the wake up.
Yet a little effort and apple will be as worst as linux to manage power...

X220 Crashes during sleep

X220 crashes during sleep, goes into a 7 second cycle of beeps and LED flashes. Multiple (probably refurbed) systemboard "repairs" didn't fix the problem. Sometimes the laptop needs to be jostled for it to happen but it can happen anytime. I know it's happened to many users and LENOVO REPS ARE IGNORING THE PROBLEM so if it's happened to you, reply here and start your own thread. Let's see if we can get some help.

FileVault 2 insecure during sleep state on 2011 Air

This security vulnerability in FileVault 2 on Lion that arose back in July 2011
http://www.frameloss.org/2011/09/18/firewire-attacks-against-mac-os-lion-filevau lt-2-encryption/
http://img.frameloss.org/wp-content/uploads/2011/09/Lion-Memory-Acquisition.pdf
was something that was easy to fix on the older Macbook Air simply by changing a couple of settings. Specifically this setting:
sudo pmset -a destroyfvkeyonstandby 1 hibernatemode 25
but on the new 2011 Macbook Air that setting causes a freeze up upon closing the clam shell. In fact any hibernation on the 2011 Macbook Air seems to lead to an unstable state that often fails in this same freeze up. The general 2011 macbook air hibernation freezeup phenomena is documented yet unresolved in different thread:
https://discussions.apple.com/message/16786155#16786155
Since you can't hibernate on the 2011 Macbook Air you can't achieve a secure FileVault 2 hibernate/sleep state where the key is stored only on disk and not in RAM. This means on the 2011 macbook air if an attacker gains access to your Air in sleep state he can retreive your crypto key and unlock your whole drive using tools that have been published since July and are linked above. You're only secure if the machine was powered all the way off.
As far as I can tell this is a major unaddressed security vulnerability which almost defeats the purpose of using FileVault 2 in the first place. I hope this problem is not being ignored because of pressure from law enforcement or something silly like that. It's one thing to make your system insecure by default.. but to make it incapable of being secured while at the same time branding it as a security product is just plain false advertising.
here is how to fix it:
If FV2 encryption is turned on then the Air should no longer support sleep it should hibernate instead, remove the FileVault key from RAM, power off the RAM. In other words this command which you already have built into the OS should be made to function the same way it does on the older air and should be default for all FV2 users:
pmset -a destroyfvkeyonstandby 1 hibernatemode 25
Sure it'll slow down wakeup but the SSD helps make that less noticeable and that's what it takes in order to do full disk crypto. You'll still have the fastest secure full-disk crypto laptop if you fix this. As I said earlier this command can be issued on the older Macbook Air and it will lead to a secure system. It needs to be fixed for the new macbook air before filevault can be secure during sleep or hibernation.
I'd love to hear tha tthis is being addressed.

Why do you think that this method is safer compared to
pmset -a hibernatemode 0
This way, all the content is stored in Ram, nothing gets written to the disk, so the key never leaves the Ram.
Newer research indicates, that you can no longer (since 10.7.2) read the content of the Ram via Firewire unless a user is logged in and the screen is unlocked:
http://ilostmynotes.blogspot.com/2012/01/firewire-and-dma-attacks-on-os-x.html
The advantage of this method would be, that the wake up is faster and a shorter password for login can be used for quick unlock. (A password of a user who is not allowed to decrypt the disk because his password is too weak to withstand automated brute force attacks, but is strong enough against a human in front of the keyboard)

T400 LED beside ultrabay lights up during sleep?

After i put the laptop to sleep, and moved it around for a while, the LED beside the ultrabay will light up. I have no idea what it is supposed to indicate, but it doesn't light up if i just leave it sitting. I noticed this weird phenominon after upgrading to BIOS 2.03. I downgraded back to v1.15 but the problem remains, so i'm not sure what is the culprit.
And for some reason the power consumption on standby isn't as low as before, as i noticed a significant decrease in battery life after leaving it in sleep mode for about an hour. The half moon LED was on throughout, so it shouldn't have woken up halfway.
Laptop specs: 2768-AA6, Vista x64.
Anyone having the same experience? What is the side LED supposed to indicate if it is on during sleep?

Hello dD-2765, welcome to Lenovo forums!
Please check in bios if Wake-on-Lan or anything else is deaktivated.
If you use a dock, then undock it and check if the problem occurs now.
Then check devices in device manager, if some device, wlan, modem or anything else, has checkbox and "device cant wake up windows" is checked.
Also start XP/Vista search, then type in cmd and type: powercfg -devicequery wake_armed
Is there a list of devices, that can wake up windows?
Please check if windows hybrid sleep is deaktivated.
May be interesting for the other members here.
"On Vista, you need to go into Power Options (shortest way is by clicking on your tray battery icon and then "More power options", or you can find it in Control Panel). Once you're in Power Options, find which Power Plan you currently have selected and then right under that plan's name click on
"Change plan settings" then "Change advanced power settings". From
there it will list a tree with the different power plan properties in
it.
You'll find the option for hybrid sleep under "Sleep" > "Allow hybrid sleep"." disable it.

Lid closing and laptop doesn't sleep

I have my setting so that when the lid closes the laptop goes to sleep (plugged in or on battery). However, the laptop does not always go to sleep. Sometimes it will stay on for hours until it dies completely. Any idea what could be keeping the laptop from going to sleep when the lid is closed? Also, it gets VERY hot and dies out in about 2.5-3 hours (though I do have it set on high performance mode). That's pretty disconcerting especially that the screen is off.

Good evening.
Could you provide a bit more information about your PC (model, Windows version, etc)?
Regards.

Fans blowing full blast during sleep

My MacBook Pro (15", 1.83GHz) will turn its fan on +full blast+ whenever it sleeps. This happens immediately, and regardless of whether the lid is closed or not. The computer goes to sleep fine from the Apple menu, and the indicator light pulses (i.e., I think it is really asleep). I've let it go all night long, and the fan never seems to stop. I can get good temperature readings from all the sensors, and the RPMs on both fans look reasonable while the computer is awake. They also modulate in a normal range during use. I haven't had any other trouble with it.
Originally, this computer was salvaged. It wouldn't turn on or charge. I replaced the left I/O board (containing the DC board), and it works fine now. I can't think of what would be causing this, but I'm open to consider that I didn't plug something in correctly as I was reassembling the laptop. I also don't know what caused the original failure of the left I/O board... so I'm not ruling out weird water damage or something.
Any ideas are appreciated. Thanks.

Hi Bill. It is worth bearing in mind that the "default" on most Macs if the OS thermal control routines can't be accessed, or if data from a sensor is not available, for example, is to send the fans up to maximum revs.
Usually when people experience the "full fans during sleep" situation it is because the system is actually "crashing" when sleep is attempted. In such situations , of course, the computer fails to actually "wake up" when asked to and has to be force shutdown! I gather this isn't the case with yours? It wakes up normally and the fans return to normal speed when it wakes?
If the OS isn't loaded (or isn't getting the right readings) , of course, the fans go into hyperdrive anyway (hence the flat out activity when running the Apple Hardware test and the like)
It sounds almost as if the computer is losing effective "Operating System control" and going into "hyperfan" mode accordingly when sleep is activated, but not actually crashing, and then recovering control on waking.
I presume you have tried things like wiping the drive and re-installing the OS from scratch and a PRAM reset as well as the SMC reset already mentioned?
Cheers

Sometimes when I open my laptop back from sleep, I get a black screen with the cursor showing.

Recently I've been getting this weird problem where my macbook air will show a black screen with only the cursor visible that I can move around but nothing else can be done to get to the desktop. The only way is to close the lid and wait for around 10 or more seconds and then open the lid again to bring the laptop back from sleep and hope that the laptop goes to the lock screen and then to the desktop. This works often but sometimes the only solution seems to be to restart the laptop. This also happens when I tilt the lid to the point where it is almost closed and when I tilt it back the screen presents the above state. Theis has been happening often now and it is almost impossible for the above not to happen atleast 2 to 3 times a day. iThis is a relatively new problem that has been occuring since the past two weeks or so and never happened to me on my Macbook Pro 15 2011. My current system is a Macbook Air 11" 2013 Haswell 1.3 Ghz 4GB RAM 256 GB SSD. Now I dont want to have to send in my laptop if I dont have to if there is a way I can solve this myself. Anybody else have this problem?

Hello tseten,
I would be concerned too if my MacBook Air was not waking from sleep appropriately. For an issue like this, I recommend resetting your System Management Controller (SMC) and NVRAM.
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Yesterday, when I brought my laptop back from sleep, I tried to check my e-mail with the Mail app like I always do. But there was the lightning bolt sign next to the inbox, and the pop-up asked me to input my password, which didn't work. It says mail.mac.

Yesterday, when I brought my laptop back from sleep, I tried to check my e-mail with the Mail app like I always do. But there was the lightning bolt sign next to the inbox, and the pop-up asked me to input my password, which didn't work. It says mail.mac.com has rejected my password. The password is correct (I'm able to check my e-mail through my browser at me.com), but for some reason Mail keeps on rejecting it. I usually don't have to input my password at all in Mail. Any clue how to fix this? I haven't changed anything at all on my laptop.

I did change my apple ID password though...

High-pitched beep/sound during sleep and shut down modes

I just wish to check whether is it normal that there's high pitched beep (not very loud but can be heard in a quiet room) which seems to be from the LED or AC Adapter during sleep mode. The beep sounds continuous when the computer has been shut down or in off mode while the main plug of where the ac adapter is connected to is still on. Is this normal? My computer works fine. Battery is charging fine. I just want check whether is this normal. It is has been like that ever since I bought my computer on March 2012.
HP Pavilion dm4-3005tx Entertainment Notebook PC

Hello Huanwei,
It appears that you can hear a "high pitched beep" coming from the notebook while it's in sleep mode or even off, when the power adapter is plugged in and "on". I will try to help you with this.
Normally, this should not happen. Beeping from a computer may happen during start up a few times to indicate components enabling, but any constant beeping or being while the computer is off shouldn't happen.
Does this occur, if the AC adapter is not connected to the notebook when it is in sleep mode or off? Do you only notices this, in a specific location? (office, etc.)
I would suggest, depending on the setup of things. Taking the notebook with no AC to another location in the house. A quiet one, make sure your not near any other electronics (no watches or cell phones either) let the notebook sleep and see if you hear the beeping. If not, then power it off and test again. If no beeping, this is good and the notebook is fine.
Repeat that same test with the power adapter connected ( again no other electronics around you). Listen while it is "sleeping" and off to see if you can hear the beeping again.
If you do disconnect the AC from the notebook , but leave that connected to the wall and take the notebook out of that location, go back to see if you can hear beeps again. If you do it could be the AC adapter. If you don't then it could be an issue with that only when it's connected.
If there was no beeping when the AC was connected in this "testing location", then I would guess it is something else within the house that is beeping (we have seen that before). In which case you'd have nothing to worry about in regard to your notebook.
Let me know where the above leads.
Thank you for posting on the HP Forums.

White 24" iMac lockup during sleep mode

I have recently been having problems with my iMac it won't wake from sleep and has to be unplugged and restarted or every time it goes to sleep it locks up. The light on the front is on but not flashing as it normally does during sleep. I run Onyx frequently and it does not seem to help for long(Maybe 2 days max) I am at the point where I am only using XP in Bootcamp because it seems to run much better than OS X.
Here are my specs:
24" iMac 250 GB internal drive, 500 GB firewire 800, 2 GB Ram.
USB devices: Wacom Intuos 3 tablet, logitech NuLOOQ, HP Deskjet 5940, VXI USB Translator(USB Audio device for speech recognition) Sentinel Safenet Dongle for Lightwave 3d.
Bluetooth devices:Mighty Mouse and Keyboard, Motorola HT820 headset for Telephony
I have disconnected everything I can and it still seems to lock up under OS X So it looks like I'm stuck with XP until I can resolve this. >:(....

First - you aren't disconnecting any device while your computer is asleep are you? This can cause your problem.
Assuming this isn't the cause, let's do an SMC reset. Shut down the computer. Unplug all cables from the computer, including the power cord and any display cables. Wait at least 15 seconds. Plug the power cord back in, making sure the power button is not being pressed at the time. Then reconnect your keyboard and mouse to the computer. Press the power button on the back to start up your computer. Does it now sleep and awake?
If not srojtas is right that one of your peripherals may be the culprit but rather than disconnecting one at a time I recommend that you disconnect everything but your ethernet cable (assuming you have one) and your USB mouse and keyboard. Create a new account and set the computer so that you have to choose which account to log into.
Restart and log in directly into the new account. If it sleeps and wakes up now you know that the issue is your account or one of your devices. One at a time, connect (and install support software for) a device. Does the computer wake and sleep? Move on to the next. You may find the culprit along the way. Removing it may or may not let the computer sleep depending on whether it is the device itself or the software.
BTW - the device at fault could be a USB or FireWire hub.

24" iMac has buzzing sound every 5 min during sleep after upgrading to is x lion

I have a 24" iMac purchased new in 2009. Haven't had a problem and usually put it to sleep mode at night with no problem. I recently upgraded to OS X Lion and started noticing 2 problems during sleep mode. One is a constant humming noise that wasn't there before, as if the computer is still running. Second problem is that every 5 to 10 min or so, a slight buzzing sound pops up.
The noise poses as a real problem during the night as I have the iMac in my bedroom. I'm forced to completely shut down very evening to avoid the noise. Can anyone help? Thank you in advance.

I have a similar problem on my early 2008 macbook pro. After the audio driver is idle for a minute or so (after an itunes playlist or youtube video ends) the headphone jack output starts buzzing horribly, to the point where i have to turn off my soundsystem or play a muted song to “wake up“ the card and stop the buzzing. This must be due to different power management parameters in Lion, as it started immediately after the upgrade and disappeared after I reformatted and returned to Snow Leopard. Maybe there is a way to force the audio hardware to stay active?
