how to enable wi-fi in sleep mode?

If you have cellular data plan for your phone and you have cellular data turned on, the fact that you do not have Wi-Fi at the time, you will still receive your messages, plus once the device starts to receive the message and "wakes up", the device will reconnect to Wi-Fi at that time.
As stated by everyone that has posted so far, the fact that Wi-Fi disconnects after the phone goes to sleep is a battery saving feature of the phone. There is no app or other setting that will change that. Only keeping the device connected to power will keep the Wi-Fi radio active.

How to put MBA in 'Safe Sleep' mode.

How do you put MBA in Deep Sleep 'Safe Sleep' mode? I have been reading many postings here and on the internet and am not getting a definitive answer. The whole topic seems to be rather confusing. Does someone have a simple answer in achieving hibernation sleep on the MBA?
Maybe someone has an example of what they are doing and how they are doing it?
Thanks and I look forward to your replies.

The best I found was using this program: http://blog.kaputtendorf.de/2007/08/17/hibernation-tool-for-mac-os/
I've placed it on my dock and use it when I want to hibernate. I liked the machine's default sleep behavior on the closing of the lid so I did not want to change it.
However, I found that the rebooting is actually faster than hibernation. It takes about half the time to boot than it takes while waking up from hibernation/deep sleep. I compared it with no applications running, which tells me why Apple did not put Deep Sleep in their menus because it is poorly implemented and does not get you the same advantages, which say as you'd have, on a Windows platform.
For example, before Mac I was using a Windows based laptop computer and waking up from hibernation was a big difference in life. My machine would come out from hibernation in 15-20 seconds - compared to 75-90 seconds it took to boot. Waking up from Sleep was comparable to Apple but the battery would be drained much quickly so I never used it for longer 'off' periods. Here my MBA loses about 1.5% of its charge every hour during sleep, so I don't mind leaving it sleeping if I know I'll be charging it the next day.
Since Mac's boot time is quite good so probably it'd make more sense to use sleep during the working hours and shutting it off overnight. Hibernation as a practical option does not exist for me if it takes longer than booting.

How can I turn off the sleep mode on my B209a

I need to turn the sleep mode off on my B209a printer,every time my computer updates and printer is in sleep mode , my computer does not reinstall printer.
usally its at a time where I need to print and I have to stop and reboot system with the printer on.

HI,
Go into the setup menu from the display of the unit and find prefferances. In there is the option called "energy save mode". You should be able to turn it off there.

How to keep the screen in sleep mode while using the Apple Remote?

i use the imac to play soft music for me to fell at sleep, but sometime i just want to turn the volume down/mute/stop. but the screen keep come back on and brighten up my room.
would this be possible? is there any program that could adjust this option?
any cmd that i could run to fix this?
thanks

I appreciate the help A Brody, but this does not solve what I am asking. I like being able to focus on something like a YouTube video without having to worry about losing my "spot" if I want to move the cursor to pause the movie. I want to do this on demand and not have to worry about clicking a bunch of different stuff or opening a screenshot in Preview.
If my iMac can do it, then how can my MacBook do it?

Mountain Lion sleep mode kills lan / internet connection - how to fix?

How do I fix Mountain Lion Sleep mode that cuts my Lan and nternet connection?

The problem is all the error messages on waking about lost connections - the machine re-stablishes all connections quickly and automatically but you are clicking off the error messages continually.
This never happened with Lion or earlier versions - it is unique to Mountain Lion.
There is something else going on because when I wake the computer I get no end of error messages that the connection was lost to the LAN or to the internet - obviously - in sleep mode or as it was going into sleep mode, the computor or a program like Aperature which has Facebook links was trying to stay connected.
Apple Care gave me a solution that lasted about one sleep cycle before the problem came back - they had me shut off the router/modem for about 60 seconds, had me shutdown the computor and do a System Controller reset while the computor was down. We then restarted the computor and all was fine when we put the machine into SLEEP mode and woke it up again - no error messages.
However, overnight, the machine went into sleep mode and when it woke up I had over twenty error messages about lost connections.
I get a new iMac later this week - we will see what happens with new machine.

MB's optical drive interrupts sleep mode for no apparent reason

Noticed this over the past few days: When I shut my MacBook's lid, the optical drive spins once or twice and even though the screen is dark, I don't think the MacBook is actually entering sleep mode-- instead, I have hit the "sleep" command from the Apple menu. Each time this happened, there's been no disc in the drive. It happened just now as well. So am I crazy, or is this unusual?
The MacBook in question is: 2.0ghz Core Duo 2 chip; 120 GB hard drive; 2 GB of RAM; Superdrive. It's a one-month-old black MacBook, if that makes any difference.
Two nights ago, it happened while the following programs were running [but hidden]: Firefox, Activity Monitor, iChat, iTunes, iCal, iJournal, Mail, LaunchBar, NewsFire, System Profiler, and Pages trial.
However, this also happened last night and only LaunchBar would have been running at the time. I actually had to turn the MacBook off last night, because I wanted to make absolutely sure the optical drive would stop spinning.
Right now, the only peripheral "hooked up" to my Mac is a bluetooth-enabled Logitech wireless mouse. Is it possible this is what's preventing the MacBook from staying asleep? I've fiddled with the Bluetooth pane's "allow Bluetooth devices to wake this computer" setting but that doesn't appear to affect when or how often my optical drive interrupts sleep mode. It's annoying when I'm trying to sleep and the optical drive spins up every 30 seconds or so until I have to shut the whole computer off. Any advice would be greatly appreciated.
13.1-inch black MacBook w/ Intel Core Duo 2 chip Mac OS X (10.4.8)

Take it in for service since it's in warranty. There may be a serious hardware problem.

Screensaver / sleep mode password protection does not work

Hello,
I am running 10.6.4 and have enabled screen saver and sleep mode password protection from System Preferences / Security / General / Require password immediately after sleep or screen saver begins.
I have also selected some screen saver - Cosmos. Now, from terminal when I check the settings:
MINE:~ ent$ defaults -currentHost read com.apple.screensaver
CleanExit = YES;
PrefsVersion = 100;
mainScreenOnly = 0;
moduleDict = {
iLifeMediaGroupType = 0;
moduleName = Cosmos;
path = "/System/Library/Screen Savers/Cosmos.slideSaver";
type = 4;
showClock = 1;
tokenRemovalAction = 0;
MINE:~ ent$ defaults read com.apple.screensaver {
askForPassword = 1;
askForPasswordDelay = 0;
tokenRemovalAction = 0;
So the settings get applied correctly.
The problem is - after screen saver kicks in or when MacBook goes into sleep mode and I want to continue work - no password prompt appears and I go back to desktop without any authorization!
I see this behaviour on admin user account, but when I login in as root - prompt appears and asks for password to unlock desktop.
Can you help me troubleshoot the problem? How can I log /see what is happeining after screen saver is terminated by mouse move or key stroke?
Regards,
Krzysztof

Gals, Gents,
I actually figured out the root cause of the problem. I am using EncFS to encrypt my home folder and each time the user logs in a script is being executed:
MINE:~ ent$ cat /Library/Management/loginhook.sh
#!/bin/bash
# $1 = logged in usernam
# try to mount /e using encfs entry in keychain
PASS=$(security find-generic-password -ga EncFS 2>&1 >/dev/null | cut -d'"' -f2)
RAW="/Users/.$1"
MOUNTPOINT="/Users/$1"
echo $PASS | sudo -u $1 /usr/local/bin/encfs -S $RAW $MOUNTPOINT
It is executed as a login hook, so:
MINE:~ ent$ sudo defaults read com.apple.loginwindow
LoginHook = "/Library/Management/loginhook.sh";
LogoutHook = "/Library/Management/logouthook.sh";
The problem with that is that most probably all the Library settings are first read and only after that is the login hook executed. What it actually does is decrypting the EncFS volume and mounting it to the /Users/enc.
So... Library folder get's substituted and I can work on Library preferences files from my account, but they are not visible during the login process.
Anybody know how I can change this process to enable login script before Library is ever read?
I managed to work around with screen saver protection by adding it globally to /Library/Preferences/com.apple.screensaver.plist instead of local ~/Library/Pref..
But obiously that is not how it should be dealt with...
Thanks,
Krzysztof

Ibook won't wake up or crashes after waking from sleep mode

I have now had this problem for the last year with my new ibook g4 and I can confirm that the problem is present at OS X version 10.3.0 - 10.3.9 and 10.4.0-10.4.5 . I'd manage to solve it but once in a while it shows up again and i have to solve it all over again. Apple doesn't seem to care although it makes your iBook totally unusable if you can't put it to sleep mode, because of the fact that you can't leave your iBook ON while the lid is closed. Ok as I said I have this problem once in a while but I allways manages to solve it, here are my observations:
Leting the computer go into sleep mode by itself (not by closing the lid) will not result in a crash.
Before a crash the following allways occour:
1) The system gets highly unstable. Programs (mostly safari, mail and itunes) will crash without warning. The mouse reacts very slowly and lags behind. The mouse lag is a shure indication that the system will crash during the next seconds or minuts.
2) While set to automaticly connect to favorite network, the airport won't connect imidiatly, but it will take a few seconds more than usual before it connects.
3) The system sometimes crashes before it can activate the backlight resulting in the situation where people think that the system can't wake up from sleep mode and won't react.
Only forcing the computer to sleep mode can cause this failure (by pressing "sleep mode" or by closing the lid).
What i did to rule out some sources resulting in this error:
1) Something like this problem can happen when having a bad memory socket or bad memory, so I'd ran Apples Hardware test and memtest OSX, but no failure was indicated.
2) Ran the usual repair of disk permissions (like 10^6 times ), without any changes.
3) Tried to reset the PMU (Power managing unit), without any changes.
4) Also tried to make a clean installation with panther 10.3 and tiger 10.4, without changes. Before installing anything (no prgrams or updates) the system still crashes. Even after updating to. 10.3.9 and 10.4.5 the problem is still present
The solution:
Well I found out that the problem has to do with to power options. That would normally mean that reseting the PMU would help, but as I already said this didn't change anything. Apparently the system is not able to wake up the Harddisk from sleep mode, and that's basicly the problem. I don't understand why it doesn't crash when going to sleep mode all by itself, but aparently there's something diffrent by forcing the system to sleep mode. Fourthermore it's not so "happy" to change those settings for the harddisk (I will explain later).
Solution:
1) Basicly just UNCHECK the option "Set harddisk to sleep mode whenever it's possible" inside powermanagment. And set "let the computer go to sleep after" to "Never" , do this for Battery and AC Power settings.
2) And put CPU usage to "Automatic", do this for Battery and AC Power settings
3) Restart the ibook. When it plays it's startup sound reset PVRAM by holding the following keys down before the backlight turns ON: OptionCommand+PR , when you hear the startup sound again release the buttons and start OSX normally.
Now as I said this problems comes once in a while and that has to do with the fact that repairing my disk permissions can change/reset the above changes. Even if it isn't beeing displayed graphicly repairing the disk permission have reseted those changes, resulting in the fact that the system is crashing again.
So to solve this do the following for Battery and AC power settings:
1) CHECK/MARK the "Set harddisk to sleep mode whenever it's possible" inside powermanagment and put CPU usage option the low or high. And set "let the computer go to sleep after" to "Never"
2) Restart the ibook.
3) UNCHECK the option "Set harddisk to sleep mode whenever it's possible" inside powermanagment". Put CPU usage option back to "Automatic". And set "let the computer go to sleep after" to "Never"
4) Restart the ibook again. When it plays it's startup sound reset PVRAM by holding the following keys down before the backlight turns ON: OptionCommand+PR , when you hear the startup sound again release the buttons and start OSX normally.
So now it doesn't crash again.
I've read all the threads of people having this problem and apparently it has been present since OSX 10.0.0 and when calling apple support they tell you to reset PMU and repair the usual disk permissions, which of cause doesn' work. And there are aparently a lot of really angree costumers, because this problem makes the computer COMPLETLY unusable, but apple has done nothing to help those people because of the the fact there there has been released ZERO patches or changes in OSX to resolve this issue. I can't say that there is something wrong with the iBooks as the several hardware test's indicate no malfunctioning but there is some bug in Mac OSX wich specificly makes the system incable to tell some ibook's how to wake the harddisk from sleep mode.
To the fine folks working on this forum: No I will not send this to apple, they already know about this, and have done nothing (just think of the millions of crash reports they recieve from those hundreds of crashes everybody is geting from this problem). That is why I put this on the forum so that people can actually solve this problem by themselves. If you think it's worth sending to apple, so that this problem can finally be fixed after 4-5 years you are more than welcome to send it directly to somebody who will actually do something about this. And i really hope that giving people the opportunity to make ther computer work, doesn't violated the usual rule "that we are not allowed to write anything that is agains apples interests", wich often results in a removal of threads and ANY chance in SOLVING critical errors.
ibook g4 12", 512, 32 VRAM, 1.2 GHz Mac OS X (10.4.5)

sdad sdsdds:
Your observations and solution are right on the money!!
I just was working on an iBook that my father is giving to my sister. I must have started the problem by changing the sleep setting for battery to let HD sleep. After that the fun began! Instability, restart after restart, running Disk Warrior, fixing permissions over and over, etc. I finally zeroed out the HD and installed 10.4. Nothing worked until I read your post.
Thanks a lot. I understand how you feel about posting here, but please be aware that you are helping many people who would be completely without a clue otherwise. Thanks again for your efforts.
Now I can ship my sister her iBook!

Monitor black after coming out of sleep mode

Every time my computer goes into sleep mode, after 5 minutes i think is what it set at, the screen is black. I can see the desktop on each side of the black part of the screen, but only about a 1/16th of an inch. I have to turn off, then back on the screen to get the picture. It doesnt seem to make any difference what i have for settings for the sleep time. Only if i turn off sleep mode of course. Ive downloaded all the updates but no success. This is a problem ive had for years just thought id take another crack at it. The monitor is a 2159m. Its about 6 or 7 years old now, but still this is very annoying. Any thing you can do to help would be greatly appreciated.
This question was solved.
View Solution.

Thank you for the response. This issue could potentially have numerous causes, so I will suggest multiple troubleshooting avenues.
First, your Windows 7 might perform "hybrid sleep" instead of the regular sleep mode. This would illustrate the exact situation you have explained. For instructions on verifying, enabling, and disabling hybrid sleep mode, please reference this website: http://maximumpcguides.com/windows-7/turn-off-hybrid-sleep-in-windows-7/
If this does not resolve the issue, the next troubleshooting step will be restoring the power defaults to normal settings. To perform this task, go to the start menu, type “CMD” in the search bar. Now, you should see a shortcut for CMD above. Right click on it, and click “run as administrator”. If it asks you for administrative permission, please allow permission.
You should see Command Prompt open. Type the following command in this window and hit Enter afterward (without the quotations): "powercfg -restoredefaultschemes"
Restart the computer afterward and observe what happens. If the issue persists, this is next command I require you to enter in Command Prompt as administrator (without the quotations): "sfc /scannow".
This will take a series of minutes to complete. Running this might find a corrupted file or service and repair it. After it completes it will basically say either no corrupted files were found, corrupted files were found and repaired, or corrupted files were found but were unable to be repaired. Restart after this completes and observe the results.
If the issue still persists, the next step will be performing a hard reset on the desktop. To do this, turn off the computer, and unplug all cables attached to the tower and monitor (including all power sources) for a few minutes. Plug all the cables back in and turn on the computer, and see if the issue persists.
if the issue is not eliminated, I would attempt all pertinent troubleshooting steps in these HP documents below (since they address causes for black screens in various situations):
http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c01881110 (this document is specific to notebooks, so please follow all relevant troubleshooting)
http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=bph04760
If the issue is not resolved, you are likely experiencing a hardware failure. At that point you should contact HP technical support for additional information. You can utilize this website to locate the most suitable number, based on your region: http://www8.hp.com/us/en/contact-hp/ww-contact-us.html
Please let me know if you found this information useful by marking it with a Kudos and Accepted Solution, and others will be able to locate this information easier. Please inform me with your results, and any additional questions or concerns. I will look forward to your response.

How can i fix my Mac book pro sleep mode

Hi i am having troube with my mac book pro which i purchased in 2010. I am running Mac OS X 10.7.4, the time it took my computer to go sleep mode before was around 3 second and now it basically took 1 minute go on sleep mode. can anyone help me on this one?

try this;
open disk utility - verify disk permissions - repair disk permissions if errors are found. might take an hour or less - depending on how much errors needs to be repaired.
restart your macbook and see if that sorts it out for you.
also check your hard drive space. if your hard drive is almost full, that will also contribute to your macbook getting slower....
good luck

How do I set iCal so that my alarms go off when in sleep mode?

I'm pretty sure that I can set iCal to open a program (iTunes) as an alarm while the computer is in sleep mode but I can't find the setting. This morning it didn't go off while in sleep mode.
Does anyone know how?

I am pretty sure that you can't. You can however use the Energy Saver in System Preferences to wake the computer at a set time, and then your iCal alarm could fire.
