10.6.8 - now Bluetooth won't wake it up

Just upgraded to 10.6.8, and now the 'Allow Bluetooth devices to wake up this computer' is dimmed - I have to switch my USB printer on or off to wake the iMac up. That's a nuisance. Any ideas?

is a Apple kext file and likely necessary.
What you can do is backup your Users folders to another external drive (not TimeMachine) first so you have your files outside of TM. Disconnect this drive for safety reasons.
Then hold c and boot off the OS X 10.6 installer disk and simply reinstall OS X on top of the installed version, then use the 10.6.8 Combo Update here
http://support.apple.com/kb/DL1399
That should replace the troubled kext file with a fresh version.
This shouldn't bother your files or third party programs unless they have kext files or other "hooks" into OS X, if these programs fail, then just reinstall them from fresh sources and/or update to reinstall their missing parts.
Consider cloning your boot drive to a external HFS+ journaled formatted drive with Carbon Copy Cloner.

P67A-GD65 (B3) I put it to sleep and now it won't wake up?

I hope that someone will be able to help me. The other night after using my computer I put it in to standby mode. The next day when I tried to wake it up it didn't respond. I tried everything that I could think of and in the end turned off the power supply using the switch on it. It finally booted up but I noticed some odd behavior right away. When I moved the mouse around it would suddenly stop in one place on the screen and the symbol would change from the pointer to the working symbol. It would then suddenly jump and catch u to where I moved it on the pad. I thought that the driver for it may have messed up so I tried to reinstall it but the computer just sat there with the working symbol showing. I used task manager to close the program then thought that maybe it wasn't a mouse problem but maybe a memory one instead. I ran windows memory tester and didn't get any errors then again rebooted the computer. It gave me a long beep and two short ones then just sat there with a black screen. The motherboard ativity LEDs all just stay lit but nothing else happens, it never even gets to the BIOS. I have tried swapping out the power supply as well as the video cards and hard drives. I have also tested these parts in another system. I tried boting up with only 1 stick of memory and swapping that ne with the other as well and still no starting this thing. I do not know what to try now. I don't have an extra motherboard, cpu, or mrmory to try. Does anyone have any ides? Thanks, Mitch

With swapping parts in & out & around, along with the original wake problem, recommend removing the PSU power cord, removing the battery for awhile, & clearing CMOS. If clearing CMOS gets it back to working, check the System Information for the UEFI version. With a non OC'd & stable system, it may then help to update to the newest version.

I put my ipod 5th Gen to sleep, now it won't wake up??

So, this is the second time that this has happened. I press the power button on the top and put my iPod to sleep but it doesn't make the lock sound (I have it set to) and when I try to bring it back up, it doesn't do anything. The screen stays black. I've tried the home button and plugging the iPod into the charger and the power button and holding down the power button but nothing works. Is there something wrong with my iPod or is this just something that I'm doing myself?

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Won't wake up from sleep mode

I have only had my iMac for a couple weeks and four times now it won't wake up from sleep mode. I have to use the on/off button for a response.

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

[Athlon64] pc won't wake up!!!!

Have a four month old pc which was put on standy for the first time and now it won't wake back up.
Have a K8tM-IL mobo
When I switch it on the fans turn for a few seconds and then cut out again, no mouse, keyboard or monitor.
Have tried taking the battery out and moving the position of the jbat1 but nothing has changed.
Anyone any ideas? - unfortunately bought this from Tiny, so no help there

Well...even though this is Athlon64 land...I'll try to help you. Unplug your PSU cable from back of power supply and unplug the main connector to the motherboard. Install new CMOS battery and reset jumpers to "drain" position, then back to normal position. Re-plug your power supply at the rear of the unit. Re-connect main plug to mobo. Plug power supply to source. Turn it on. If it doesn't come on....your CMOS memory may have drained, or it might be your PSU has expired..

Won't wake up printers brother hl1440

my mac pro used to startup my brother and hp printers from sleep,until I had a fresh install of 10.6 now computer won't wake up printers. yes I do have the newest drivers.If i disconect the printers from the mac and install the software again it works till the printers go to sleep and then it tells me it's off line!!any help out their! thanxs

I'll have to try this fix David!
I have a Brother 5170DN and a 2070N and they both seem to drop their ability handle print jobs, yet not their IP addresses. In my case, I have both setup with a Static DHCP address given out by my router, which gives me the ability to always know where I can check to see if they are online; however, even if I can use the web-admin site onboard the printers I still am unable to get them to spool a print job. Since your fix is basically making the IPs legitimately static and not DHCP forced static --as in my case-- I wonder if this is not an issue with the printers' release time on the DHCP address. I typically notice my problem every couple of weeks or so.
Anyway, thought we might be able to dig a bit deeper than just the fix that you suggest --I'll let you know if it works for my two printers.

I'm using a late 2006 2.33GHz imac.I clean installed 10.6 from disc then updated to 10.7 from download.Now every time my computer goes into sleep it won't wake up.Anyone know how to cure this problem please??

Now every time my computer goes into sleep it won't wake up.
The only way it will restart is to pull the mains lead out of the imac, put it back and try until it will start.
This only happened after reinstalling. Only Apple OS was on the imac and so it must be an issue with the software I believe.....
Anyone know how to cure this problem please?
Thanks

This isn't a fix, more a workaround I used when I had wake from sleep problems that lasted from some point in 10.6.x, through 10.7 and into 10.8 (got fixed for me in 10.8.2). It seems to be connected with Bluetooth failing to wake up properly:
System Preferences>Energy Saver and set 'computer sleep' to 'never'.

MacBook won't wake up from sleep and Bluetooth Settings (Possible fix)

Hi,
I rest my SMC as per the instructions. I've done this a few times before and it my system sleeps one time correctly then glitches as previously noted. However, this time I did not use any Bluetooth device but I was connected to the internet via my wireless router. The computer has successfully entered 'sleep' and woke up several times without a glitch (white light flashing in front during sleep).
I the tried various Bluetooth settings starting with switching ALL the choices listed under the Bluetooth Advanced tab to off. I then switched on my Bluetooth mouse, used it for a while then I switched off the mouse (Microsoft Notebook Mouse 5000) and waited for the laptop to give the 'lost connection' notice. Once the notice disappeared I close the lid and the system entered sleep again (white light flashing in front) and woke without a hitch.
Next I restored the default Bluetooth Advanced tab settings including the ‘Allow Bluetooth device to wake system’, reconnected the Bluetooth mouse and used it for a while before closing the lid and placing the computer in sleep mode. I left the mouse on. Something very interesting happened…….the system properly entered sleep mode with the front white light flashing, I then intentionally moved the Bluetooth mouse and the system tried to wake with the lid closed. I saw the Apple logo light up briefly then shut off AND I also heard the Superdrive mechanism respond. The white light in the front of the system stopped flashing and just stayed on. The system would not wake. I had to hold the power button down till the white sleep indicator light shut off the boot the system back up. It is important to note that I DID NOT reset the SMC.
Once the system rebooted I made one change to the Bluetooth Advanced tab settings, Specifically, I switched off the ‘Allow Bluetooth device to wake system’. I used reconnected my Bluetooth mouse by turning it on. Used it for a while then closed the lid. The system entered sleep again (white light flashing in front) and woke without a hitch. The sleep mode works equally well now if I close the lid or select sleep from the menu.
I realize this may not help everyone but it has aleviated this problem, at least for the present on my system. I hope this helps some folks as well as the Apple techs.

Hi,
Just an update, it has now been one week since I modified my Bluetooth setting as per my post above. The computer is still going to sleep and waking without problems.

Since the latest apple update, voice navigation has gone away. Tried the Airplane mode fix, which worked, but now my bluetooth won't work in my vehicle. What's up?

Well Bababooey if you're comparing yourself to a Apple Genius Bar then you should already know my answer, your snarky remark get a snarky reply. Why would I go to a salesperson to fix my computer problem when I can go directly go to the source itself. I used to sell Apple computers over 8 years ago and was apple certified before the Genius bar existed. If I am to go about fixing an issue I can't fix on my own I will go to the source itself meaning Apple's programmers and developers - being UI UX Developer myself I know they should have QA'd all platforms and troubleshooted any arising issues.
This was also the first time in the 20 years I've been using a Mac that I even attempted to go on this forum which i thought would put me in connection with a certified Apple representative. This turned out to be a complete waste of time just being a public forum with no Apple employee involved. I was hoping to find a quick fix but in turn I was only frustrated with stupid responses such as yours that were in no way an answer to my original question.
BTW I fixed the issue on my own and without your help or Apples help. I'm glad if all forums point here regarding this issue because I now have the answer. The answer I was looking for from someone earlier was as simple as this {Download Maverick and reinstall the platform - it will take an hour to do but afterward 10.9.2 was installed and my computer is now able to shutdown and restart without having to do a hard boot.} No more software update bar at top and no problems with my drive which I told both you and Grant - I know my computer better than you and I've probably been using them longer than you.
So again Babowa you were so wrong...... and I am right.
Again anyone having the same problem, I suggest reinstalling Maverick and you'll be suprised 10.9.2 will work fine.

Sleep - won't wake up, and now randomly goes off to sleep

Since the recent security update, my 1.67 G4 Powerbook has been experiencing problems with sleep. Sometimes it won't wake from sleep, forcing me to hard reboot or pull all power out, and now it's randomly falling into sleep when it shouldn't.
The issue is progressive - it will sleep, then I wake it, then it goes down again 2-3 minutes later, wake, then seconds, wake, then deep somnambulistic slumber.
I read in Macintouch that there was a fix recently for Intel MacBooks and sleep, but some of us in the PPC world are feeling it's effect.
I've reset the pram several times, and on one occasion the fan spun up very loudly on boot, then quieted down after 5 seconds. Might be nothing.
Another factor is the battery - pull the battery and the system behaves better. I wonder if there's a lowered thermal limit that, when the battery is charging, causes the system to shut to sleep...?
Anyone else having this problem? I'm ready to slip back to 10.4.9 to see if that makes it more stable -- this happens several time a day now.

For other who may be watching this...
The laptop did keep shutting down into sleep, but - following from a tip from another site - I began trying three things: One or all seem to have resolved the issue:
* Repair permissions - often and always. Something does get munged and I'd be interested to see if anyone else has the same files affected:

* I stopped zapping the PRAM when it went to sleep or wouldn't stay awake on boot - I just booted from DVD instead and, lo and behold, the thermal errors didn't occur under the DVD. Fixed permissions and a reboot it often worked fine for hours.
* Running it alternatively from either battery or from mains. Initially under the battery, it would sleep at 70-60%, then - after a few days of being shut down instead of slept - it began running down to 0. I'd have to plug the unit in and charge it whilst off, but now -- after a week of this - everythings back to normal.
Ultimately, I'm sure this software. Something is up - and slowly, if you're patient, you can bring your system back without buying a new case or motherboard.

IPhone 4 Bluetooth automatically "going to sleep", won't wake up until bluetooth is cycled on/off

Hey guys,
I've had this problem for a while, but just recently it's been getting more and more frustrating.
I have an iPhone 4, and whenever I get into my car, my car will automatically search for the iphone to connect to. Now, normally this is great! Except that, after a few hours of non-use, my iPhone's bluetooth connection will require that I either A. Click on the car's bluetooth profile in the bluetooth menu to "wake up" the bluetooth (which involves the phone automatically cycling bluetooth on and off) or B. Manually turning bluetooth on and off.
Is this normal? I thought that if I left bluetooth "on" it would be waiting for a connection and would activate automatically when something was trying to pair with it. Any insight?

Anyone?

Won't Wake From Sleep

I held off from posting this until I'd scoured the boards looking for ideas, but I'm totally out.
Every since I updated to 10.4.8, my MacBook Pro won't wake from sleep. I've tried resetting the SMU and PRAM, enabled and disabled bluetooth device wake from sleep, and installed the latest EFI Firmware update that was just released. I've now narrowed it down to the 10.4.8 and a change in how it handles Expresscards. If I have my NitroAV FW 800 card plugged in during a session, it seems to prevent the MacBook from going to sleep properly. According to various Console messages, the PCI device prevents the computer from going to sleep, and /or places the computer into System Doze instead, from which it won't wake. The sleep light stays fixed and steady, only disappearing if I press the power button (it only reacts to the power button). From there the screen remains dark and all plugged in device fail to respond. I can hear the drive spin back up.
It reacts the same whether or not I eject the card before putting the computer to sleep. This behavior was not present before installing 10.4.8 and having fallen back on a back up of my 10.4.7 install, can say it's not present in the older OS version. I was hoping last night's EFI firmware update would deal with this, but after having installed it and 10.4.8 anew, I'm having the same old results.
If anyone has any new ideas or can direct me toward how I can make sure the folks at Apple see this, I'd greatly appreciate it.

Added second monitor computer won't wake up

I have reviewed several support threads on the subject of a 2008 Mac Pro not waking up after it goes to sleep. I have a 2008 mac pro that was working flawlessly with a 26 inch asus monitor. My bluetooth mouse and keyboard would wake it up instantly. I decided to add a second monitor, a 27 inch planar.
I had the mac set up to save power and after just five minutes of non-use it would go to sleep. My wife asked me if I would keep it on longer so she could watch the pictures that show up through the screen saver so I set it to 15 minutes and then it goes to sleep. Now though, if it goes to sleep it won't wake up and remote connections from an imac fail to awaken it as well. I am forced to hold down the power button to shut it down. I have tried the startup where I hold down command option p r but I can't get it to sound a second chime whether I start after the first chime or before the gray screen appears. After trying this every other restart does not work, the fans turn on but nothing else happens. It is quite odd. I am at my witts end. I suppose the proper course of action is to disconnect the second monitor and see if it wakes up, but I am hoping before I do that that someone might weigh in on the issue and solve it. I guess I should also try a usb keyboard as well. Thanks in advance for reading this and I hope you can help me out with this. John

Ok, here is where I am at. I reseated the two dimms. They are now showing up. I still can't get a PRAM reset to work and I have not obtained a USB keyboard yet. I reset the PRAM on my imac with a bluetooth keyboard and it worked so I believe I am doing it properly. I reset smc via following directions on an Apple page. I am hooking up the second monitor now and will see how it goes. I will keep you posted. Thank you.

My ibook won't wake up

I have only had my ibook G4 for a few months and occasionally when I shut it down, it takes a few tries brfore I can get it to turn on. The last time I put it to sleep, it won't wake up. It was over 50% charged before I put it to sleep, but now when I check the battery on the back, only one button flashes?! It seems that when it is sleeping, it is draining the battery or something. I usually get 3.5 hrs or so of use on a charged battery, so I don't think it is a faulty battery. I don't have applecare and my 90 days are up! Does anyone have any suggestions on what this could be?
ibook G4

First of all: Get AppleCare (or a warranty extension from a local Apple dealer)! You can buy it within the first year, it isn't limited to first 90 days. Seriously, if you're not habitually buying a new computer every year or so it's worth it. Notebooks (usually) do get carried around a lot more than desktop pc and bad things happen (e.g. the hard disk in my PowerBook died after a little more than a year—mechanical failure, probably more Seagate's or whomever's fault than Apple's).
How long did leave in sleep mode when it drained the battery? (Yes, it also needs energy in sleep mode so after several hours it will run flat …!
Try resetting the PMU (see here)! (You know it worked when the date is set to 1970 after booting.)
Also, maybe the battery already is damaged after all (something that happens, too—I had one that went from 50% to zero without waring).
With the right energy saving settings, a thoughtful use of screen brightness and all unused network devices (ethernet, wifi eventually and also bluetooth) in my experience an iBook battery should last up to 5 hours (depending on your usage, of course!).
My advice: Try not to let the battery run flat after the initial calibration (see Apples support docs, I'm too lazy to google them up)! You can (re)charge it any time, but letting it run flat will diminish its capacity!! (Works like that with most modern devices with rechargeable batteries (cellphones, iPods etc.). Unfortunately many people still think it's better let them run flat every time like in the old days.)
Mind you, a notebook battery will suffer wear and tear and will need to be replaces at some point …
Hope that helps!
