Change to sleep mode (hibernatemode) won't stick

I have a brand new MacBook 2.1GHZ (upgraded to 2GB RAM) and am trying to get the "old" sleep mode working instead of safe sleep.
After issuing the command "sudo pmset -a hibernatemode 0" and giving the password, it appears to work fine for a bit, but quickly reverts to mode 3. I can't figure out what might be doing this.
I need to be able to pick up and move fairly often and I'd rather not have to wait the 20-30 seconds it takes to write the contents of RAM to the hard drive.
Any ideas? Was there some change to the newest generation of MacBook that causes this to revert to safe sleep on its own?

Mine does this also. The two buttons on the bottom light up but the screen stays black. This is my second phone (exchanged the first for doing this during the two week grace period) and it is also doing this. The only way to get the phone back is to pop the battery. It isn't a screen setting. There is a thread about it here also of many others who are having this issue. Any assistance in solving this issue would be great.

Ever since my iphoto library crashed (ran out of space without warning) my mcbook pro has been slow, unresponsive, freezes in sleep mode and won't restart... please help.

Hi everyone
Ever since my iphoto library crashed (ran out of space without warning) my mcbook pro has been slow, unresponsive, freezes in sleep mode and won't restart...
I've since backed everything up on an external hard drive, removed the corrupt library, even reinstalled the operating software and there is now hardly anything on the hard drive, it still runs painfully slow. If I close the lid which puts it in sleep mode, it either doesn't go into sleep mode but instead the battery just gets drained and I find it completely empty of power (it won't start again unless plugged in), or it goes into sleep mode but just freezes when I try to reopen.
In iphoto (reinstalled) but even other applications it is painfully slow, not like a mac at all!
I am trying to go to genius bar with it but thinking maybe someone in this forum can help...
Many thanks
Andre

Have you tried SMC and PRAM resets?

Ethernet ip address changes in sleep mode

Sleep mode changes ethernet ip address - cannot connect to internet.

AFAIK the recovery mode only supports DHCP and not setting up the IP informations manually!

Window 7 64 bit - sleep mode - PC won't wake up

Accidentally put PC into sleep mode from start button. Power lite initially blinked. Moving mouse, hitting space bar or "sleep" key on keyboard does not work. I held power button down for 5 seconds, and PC started beeping. Held power button down again for seconds and power lite stays non, not blinking, but blank screen. HP monitor says "no signal" and then it goes into sleep mode. How can I "wake up" my PC?

Won't wake up from sleep mode, keyboard won't type

When in sleep mode, can not wake, keyboard will not type. So far had several problems with Lion. First Time ever my imac slowed to a crawl and forced me to m power off.

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

MPB gets very hot while in sleep mode and won't come back on

I've had this happen to me twice now, and I'm not sure what's causing it. Here's what happens.
I put the MPB into sleep mode, put it in my backpack, and when I open it a couple hours later, the machine is very hot to the touch and the fan is whirring away. On opening the lid, the display will not come back and the only way to fix it is a hard restart.
I checked the battery indicator on the side, and surprisingly, it had 3-4 green dots, so it had plenty of power.
The only common denominator I can come up with is that both times this has happened I had been using Fusion 2.01 during the day, but had closed out of it before putting the computer to sleep.
Any input would be welcome!

OK, we are clearly on the same page. We can now exclude (in all probability -- see below)) the lid coming open.
BocaBoy wrote:
Graham, thanks for the response. Since this happened the first time, I've been very careful about making sure the lid is closed and that the Apple light is out. I have seen the light go out, come back on a few seconds later, then go back out again.
Pulsating. A one-second on/off display of that light?
Yes, I'm referring to VMWare Fusion 2.01. This problem only seems to occur when, during the day, I have been in Fusion running my Boot Camp partition as a VM. I want to stress the fact that I close out of Fusion before I put the computer to sleep. I agree that there is something that Fusion is doing to the display adapter that may be causing this problem. The argument against that is that it isn't consistent. There are times I've used Fusion and successfully put the computer to sleep.
OK, so then if this works sometimes, what is different about these times. When you use the Windows software (or even the Mac software come to that -- there could be a conflict) is there any software that may still be trying to access the internet or other processes (in my earlier reply I mentioned iStumbler -- a network utility -- that caused me some slight annoyance until I realised what was going on).
The only other thing I can think of is that if my car goes over a bump that the lid is bouncing opening slightly, causing it to flick on from sleep mode, then go back into sleep. The fit, however, is tight and secure in my pack, so I'm really skeptical of that explanation.
Agree. Although it should not be excluded 100% until proven. Keep an open mind. I take mine on Bangkok buses and believe me, they bounce. I have never had my MBP come on.
No I haven't done any "maintenance" except being manic about doing a SuperDuper backup once a week along with Time Machine. What do you suggest?
Glad to hear about the TM: I wish more would back up.
I think if this were me (it has been) and I were having to do a forced power off, then my first reaction would be to try a safe boot; and then to boot up again. That at least would deal with any stray temp files and/or processes that were cut short. If this happens too often, I would be looking to stronger utilities, more to be on the safe side than to make repairs.
I would also be looking in the Console: a check of the times between when you sent it off to sleep and the time you found it at work, might show what is waking it up. Also, when you do find it running (and can get in) see which processes are active at that time. If you cannot, then the Console is your only resource, methinks.

Help! Stuck on white screen after sleep mode and won't start again!

Bought the iMac last week, updated to 10.5.1. Worked well until this morning after I did a security update. Then put it in sleep mode - and basta! After I wanted to work on it again - it didn't restart. So, I had to switch off using power button, but it never started again and always got stuck on the white screen with the Apple logo and the rotating loop. Tried to repair permissions - cannot do it, as it says there is an error. Tried to re-install from DVD the Leopard while archiving the previous information - can't do either - says error. Now trying to re-install it again with an erase option. But this is not a good option, people! This is pretty very much disappointing, Apple!
Can anyone help, please!

Boy that is way too bad.
Could you tell us what the error message was?
While sometimes the error messages are not very informative, other times they are. That might be a clue as to what is going on.
When you restart from the DVD you have the option to access Apple's Disk Utility and repair the disk.
You might want to try that, skip repairing permissions at this point.
You can also reset the computer by unplugging all cables including the power cable for at least 15 seconds and then plug in the power cable and keyboard and restart.
You can reset the PRAM by holding down the command-option - p - r keys simultaneously during restart and waiting for the startup chime then releasing those keys after the second chime to allow the start to continue.

HT3205 Hi, 2011 MBP went on sleep mode and won't turn back on, charger and indicator shows green light, led in front on Trackpad lights on for 2 seconds then back off, MBP won't turn back on, what happened???.

MBP went off and won't turn on again. Charger shows full battery ( green indicator) although I know I was close to low batt befor going off. What happened???

Thank you for your detailed troubleshooting attempts. Very helpful. Sorry, I cannot read "logs." My eyes just glass over on those things. Hopefully, a knowledgeable user will come along shortly to decipher for you.
I noticed from the pics that your location setting is "untitled." Have you tried the "Automatic" setting? Run the diagnostic test? Results?
Try the basics first:
Change your router channel number. Most times this works & is all you have to do.
Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.

Changing Open With Default App Won't Stick...

I have a couple of versions of the same app installed and I need the older version of the app to be the default app that globally opens whenever I double-click one of its files.
I've tried the Get Info -> Open With -> Select App ->Change All procedure but after clicking the Change All button, it immediately reverts back to the newer version of the application.
I need to be able to support both versions of the app. I've tried downloading RCDefaultApp but that didn't help. Moving the newer version app to another partition is not option. Re-installing the newer version of the app onto another partition is not an option either.
I would be grateful for any suggestions
Thanks,
Jon

The two Get Info options seem to use different methods to select the application. The 'Open with:' changes the Finder's default application property, but it looks like the 'Change All…' button uses the file type identifier to find the default application. Since the file type identifier is usually the same for all versions, the latest version is apparently the one that gets used. You should be able to select the older version on a file-by-file basis, or use the file inspector to change multiple documents. An AppleScript could also be used, perhaps a folder action to change the default application for files dropped into a folder.

Network connection keeps changing after sleep mode

I bought a brand new iMac for my mom just over 2 months ago and have been having internet connection problems. Sleep is set manually going under Apple and hitting sleep. Every time it's woken up after sleep the internet connection is gone and has to keep manually being switched to our network name which is quite frustrating. Tried this fix found on an old link on here: http://osxdaily.com/2011/11/06/lion-wi-fi-problems-solution-mac/?utm_source=feed burner&utm_medium=feed&utm_campaign=Feed%3A+osxdaily+%28OS+X+Daily%29&utm_conten t=FaceBook
and it didn't work. All the threads I found were from 2010 or 2012. Just wondering if there is a recent fix on here.

Welcome to the forums!
Only if it's Ethernet, not Airport/Wireless, because the radios are shut down to save energy.

Mac book goes into sleep mode it won't always come out the keyboard lights up but the screen will not

it seemed to start after i updated to OS X lion.

I have this same issue. When experiencing this issue I connected a wired mouse and selected/reviewed bluetooth device status which showed blutooth devices not connected. Trying to reconnect and/or restart the bluetooth devices (keyboard, mouse, and trackpad) did not work. Only a reboot solves the problem. Reseting the hardware does not prevent this issue.
Apple support informed me that this is a known bug and they are working on it. There is a bluetooth issue with supporting three bluetooth devices that manifests after sleep. My work around was to use only bluetooth keyboard and magic mouse. This solves the problem. After each OS patch is applied (in future) I plan to check and see if the issue is solved. I did not upgrade yet to to patches released in Feb. 2012 - so it might be fixed there (as part of the wifi sleep issue solution).

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.

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!

Laptop won't wake from sleep mode.

My laptop will sometimes spontaneously go into sleep mode and won't awake unless I remove the power cord and battery. At the same time I notice the top of the case/tracking pad get very hot. Sometimes when typing normally the cursor location will jump around your text and mess up your sentences. This is very annoying and I can't seem to make this stop from happening. Another thing I am noticing is system performance is slowing down, and the HDD is making a humming noise. Not sure if these are all related.
I've seen/read some threads on the sleep mode issue, but not the rest. Any seen anything like this? Laptop is still under warantee and I might just have to take it in, but I want to make sure I have issues with the hardware.

Welcome to the Apple discussions.
You've raised a few issues. First, to try a fix for the sleep/power issue, reset your Power Mangement Unit described at http://docs.info.apple.com/article.html?artnum=14449
Next, run your Apple hardware test. Insert the first OS X DVD that came with your system (should say AHT Version n.n in small print on the DVD), and reboot holding the option key down. Choose Apple hardware test, and follow directions. Choose the extended test. If you have one of the TechTool programs, that does the same testing. Does this point out any issues?
Performance slowing down...how much data do you have on your hard drive? You want to keep at least 10% free for system usage. Do you keep your system on 24x7? If not, there is a chance some of the system disk log maintenance won't run. You can run a program like MacJanitor or OnyX to clean them up. MacJanitor can be found at http://personalpages.tds.net/~brian_hill/macjanitor.html and OnyX can be found at http://www.titanium.free.fr/pgs2/english/download.html . I prefer OnyX because it does much more than run the Apple scripts, however, either tool will run the scripts.
When the top of your case seems hot, you should look at your Activity monitor, located on your hard drive in applications/utilities, to see if anything is causing the CPU to run up to 100%.

My iMac goes into sleep mode, won't come out until I unplug and replug the computer then hit the power button. Just hitting the power button alone won't restart the iMac.

My Imac goes into sleep mode but won't come out. The keyboard/mouse won't rouse it and the power button won't do it either. I have to unplug the computer, re-plug it in and then hit the power button. Help?

I looked around the internet and found an old post that seems to have solved the problem. I had a relatively new USB port (powered) that I unplugged and, ta da, the problem disappeared. I'm not sure why this happens (I'm not a tech person) but it seems like this should have been worked out in testing somewhere.
