Lost Bluetooth Connection when in Sleep-Mode

Hey,
when i have three devices hooked up with bluetooth to my 2009 27" imac (keyboard, magic mouse, magic trackpad) it randomly looses its bluetotth connection.
so i have no possibility to type my password to log in.
it mostly happens when the mac is in sleep-mode for longer period of time like over night or so.
i have to restart the system with on/off-button which realy ***** ...
does somebody have the same probs? or better a solution?
thanks in advance...

My 3gs disconnects from my wi-fi at night while plugged into my wall charger causing my AT&T data usage to go over my 200mb plan. I like to listen to a radio app overnight and this situation is quite annoying. AT&T forgave the overage but had NO solution to my paltry wi-fi delimma. I am going to try the "sync while connected to wi-fi" setting in I-Tunes but I am almost afraid to try it again because the overage may not be forgiven this time and It's not worth the hassle. I have been using my Macbook instead for this duty with no worries of an overage. I'm also a Pandora fan and this has limited me to just using my I-Tunes library for music instead of Pandora. This is a problem that benefits AT&T and I'm sure they bill for LOTS of overages because of this problem. I hope the I-Tunes solution will FIX this glitch.

My Photosmart Plus printer seems to lose connectivity when in sleep mode, how can I fix this?

My new photosmart plus appears to loose it's connection when it goes to sleep. At least the printers status page online says it's not connected, even though it is visible in my router and the blue light next to the antenna of the printer is on. It also appears to be connected when I poke around in the printer's settings, but if I want to print something from an app or via e-mail I have to run the wireless wizard again, select my netgear and enter the password. Once connected I get a screen where I supposedly can skip printing a report, but that does not work either, it prints no matter what I select, waste of paper and ink.
I searched around but found no solution that would work for me.
Tech info:
wireless conection to my cable modem with Netgear router
Macbook pro and an older HP laptop are in use.
Security is WPA2-PSK [AES]
I like the machine a lot, but this is rather anoying, what can I do to keep the connection when the printer sleeps?
(edited to add security info)

Does the printer not wake from sleep for both the Mac and PC?
You may want to try setting a static IP address for the printer:
- Print a Network Config Page from the front of the printer. Note the printer's IP address.
- Type that IP address into a browser to reveal the printer's internal settings.
- Choose the Networking tab, then Wireless along the left side, then the IPv4 tab.
- On this screen you want to set a Manual IP. Enter the current IP address.
- Use 255.255.255.0 for the subnet (unless you know it is different, if so, use that)
- Leave the gateway and DNS blank. Click 'Apply'
Now, shut down the router and printer, start the router, wait, then start the printer.
After this you may need to redo 'Add a Printer' using the new IP address.

My macbook pro 2.0 early 2011 will not go to sleep with the power source connected. only enters sleep mode when running on battery. Someone did this happen, and it could solve?

Alo, my Macbook pro i7 2 GHz Intel Core i7 (early 2011) will not go to sleep with the power source connected. only enters sleep mode when running on battery. Someone did this happen, and it could solve?

There is no output from that command line? Maybe the pid changed.
I'll repeat what I am trying to find out...
1. You do a pmset -g on the terminal.
2. The output from that pmset should have a line that says "sleep 0 (imposed by n)" where n is some number.
3. The ps ax | grep n is supposed to display what the process associated with n is.
It's the output from step 3 that should indicate what is causing you not to sleep.
But speaking of sleep, that's where I am going.

OS X Lion: Fix for wireless not reconnecting when exiting sleep mode

http://www.tech-recipes.com/rx/18931/os-x-lion-fix-for-wireless-not-reconnecting -when-exiting-sleep-mode/

I have the same symptoms with a 2011 iMac and my Senheiser Bluetooth headphones.
10.7.3 did not correct this bug.
I'm also using MS Messenger and notification sounds are also buffered until the headphones are switched on.
I found other threads dealing with this bug :

I'm currently trying the tip given in the last discussion :
"Success - in the Audio Midi Setup (Applications/Utilities) I changed the output to 2ch - 32bit Float and all the audio works well."
My headphones already had this setting, but internal speakers had 2ch - 24bit... is it a possible explanation ? Time will tell ...

My iMac suddenly no longer connects to wifi network when in KIOSK (username) mode, and only connects when as ADMINISTRATOR mode. Its strange because the iMac has been working fine in KIOSK mode for over a year until 2 days ago.

One of the memory cards was indeed faulty, and the other completely fine
Thanks very much for all your help!
Although there is one little thing that I've noticed. The iMac works properly, but I tried to software update to see if that may help my Minecraft sound issue (as I still don't think only having 2GB instead of 4GB would cause such a problem) but the software update application won't work. Running the "Software Update" from the apple menu on the toolbar gains no response, nothing happens. If I run the software update from system preferences, the application icon appears for a second, then disappears (as in the blank app. icon, the blank canvas with the pencil, pen and ruler in the bottom right corner). It does this every time I try to run it. It did work when the computer was crashing, but this started when on one of the occasions I ran the app. while it was crashing. Since this occured during the crashes, and still occurs now, I'm wondering did something simlar happen minecraft, as it's sound disappeared during the crashes and is still gone now.
However, the computer is now working again without crashes, which is the main thing, thanks for helping me fix the issue
Edit: I would mark the topic as solved, but I'm unsure if this would lock the topic or something simlar, so I'd rather leave it open for any ideas regarding the software update and Minecraft issues I'm having

When in sleep mode iPhone 4 loses signal but when it's back on it searches and finds signal. Was 5.0.1. update to 5.1 but no changes

When in sleep mode iPhone 4 loses signal but when it's back on it searches and finds signal. iOS was 5.0.1, update to 5.1 but no changes.
Battery problem, anntena or motherboard? pleas help.

it could be a motherboard problem. Last month I spilled liquid on to my iphone and since I didn't have warranty for it I had to take it to a "phone doctor". He fixed it but mentioned that motherboard is working fine but he can not say for sure for how long it will last, and that I may experience some wierd problems. I'm having this exact problem the day I got my iphone back.
Well no longer but the solution still seems wierd. I turned on the "location services" because I saw in the "system services" screen that "cell network search" was turned on. I figured if I don't screw with location services, it would be okay. So, after three hours, I terminated the sleep in 10-20-30 minutes and 1 hour intervals, it seems I no longer have the problem but I'm going to sleep over it to be sure. Also make sure to turn on the "auto" option on the "carrier" menu.
I will post the outcome if I don't forget about this page.

Network disconnect when in sleep mode

Hi all.
Since I've installed Mountain Lion, any time the computer goes into sleep mode, networking do the same: I cannot download files, when the computer wakeup I have to wait the reconnection before being able to use mail, safari or ather network stuff.
I did not find any option to set, telling the computer waht to do when in sleep mode.
WIth Lion and preceding OsX this was not an issue.
Is there anything I can do?
Thanks.
Federico.

Hi,
Yes, clear "Allow the computer to turn off this device to save power" in the properties of network adapter\Power management as mentioned in the link provided by arnavsharma, and check if the issue persists.

Strange noises when in sleep mode???

Hello,
Have had my brand new 27 inch iMac for about 3 weeks now. This is my first Mac computer. When in sleep mode the iMac sounds like it wants to start up and then there is a clicking sound. Just wondering if this is normal. . .or, should I shut the computer down?
Thanks.

To me any clicking sound is not normal unless on a Mouse or Trackpad. Do not delay to have it investigated, take a look at Apple returns and refunds from here.... http://store.apple.com/uk/help/returns_refund

Phone not ringing when in sleep mode

Over last few days have had problem with iPhone 4S not ringing when in sleep mode. I have just spoken to Apple support. I had do not disturb scheduled , but this was staying on all the time , which I hadn't realised. This is a fault which should be sorted by 7th Jan. hope this helps anyone else with same problem, as I did search this site first.

This is the exact problem i'm having right now, I don't know why it's happening, but when i have it on the desk and when it's in sleep mode, I can get phonecalls and it won't ring but it won't show up as missed calls either, if i get a voice message i'll get it if i take it out of sleep mode and let it sit with full reception for a minute.
I also lose all reception while in sleep mode.

When in sleep mode iPhone 4 loses signal but when it's back on it searches and finds signal only recently doing this and because it's searching for signal battery not lasting very long please help

When in sleep mode iPhone 4 loses signal but as soon as its on again it searches and finds signal easily but because of this not getting calls or text msges and because it's searching for signal all the time battery not lasting

Here are some observations and a suggestion.
1) I mentioned before, that the number of views of this discussion forum is fast approaching 100,000. I suppose relative to all iPhones sold that is not a great percentage, but 100,000 still sounds pretty impressive to me. Consider also that many people probably have this same Sim problem and are not viewing this discussion forum because thay do not know it exists. How many people are REALLY experiencing this problem? Who knows. But I suspect it is more that 100,000.
2) To the best of my knowledge, Apple does not consult these forums as a guide to awareness of product performance. It may be company policy, but most of the time when I speak to an Apple employee they seem remarkably unaware of the "Top Stories" in the Apple Discussion Forum. This, despite the fact that my personal experience with customer service at Apple is excellent. So, as much as we of this discussion forum are confident SOMEONE important at Apple is reading all our posts and taking them to heart...I am not so sure.
3) I have been told over and over that the best way to gain Apple's attention regarding a problem is to post a comment on their Feedback Site. One comment about a problem is pretty worthless. 100,000 comments on the same issue, I'm guessing, will really get their attention.
4) Some folks have mentioned a recall to address this problem. Although such a thing is always a possibility, I don't see it happening. Why? When the brakes on a Toyota don't work, or that Toyata starts to accelerate without driver intention...well, that involves human life and the stakes are quite high. For many reasons you would see the automotive industry eventually be forced into a recall program under such a situation. But, a phone APPEARS to not nearly be such a life and death device. Or is it? My daughter's iPhone 4S developed a "SIM FAILURE" on the same day her car broke down in the middle of the very rural area we live at around 10:00 pm. She is 17 years old and was coming home from high school play practice. You can imagine the anxiety I and her mother felt when she did not arrive home on time. She eventually walked about a quarter mile to a house of a stranger and had to ask to use their phone to call us. Now, I am not saying that strangers where I live are not to be trusted. But, in addition to being worried out of my mind, I was not happy that an inoperative iPhone 4S caused my daughter to be put in this situation. My biggest concern now is...when will my daughter's iPhone become inoperative again due to SIM FAILURE?
5) The more folks in this discussion forum who post a comment about this issue in Apple's feedback site the more pressing this issue is going to be perceived by Apple. So, I like others, encourage all of you to do so. If this seems like a lot of effort, I offer you these few sentences below that you could just copy and paste into the feedback site.
The link to feedback site is: http://www.apple.com/feedback/
Feel free to use copy/amend/whatever the following as you wish:
Dear Apple,
I wish to register a strong concern about my iPhone's unpredictable inoperability due to failures somehow associated with it's SIM technology. For me, I do not consider this just a significant lack of convenience, but a significant safety issue. Should I need my phone in an emergency situation where it is experiencing a SIM FAILURE, I believe the iPhone will have put me at risk. I would ask you to please give fixing this problem your greatest priority and effort.
Sincerely, XXXX

How do you prevent the computer from shutting down when in sleep mode?

How do you prevent the computer from shutting down when in sleep mode and plugged in?

Thanks tjk.
Those are great suggestions and got me looking in places I had not considered before. Unfortunately, the problem remains. The System Preferences did not have the shut down option activated and there are no parental controls active on the computer.
Any other suggestions are welcome.

QOSMIO x870 shutting down when in sleep mode

I'm not sure if this is working as intended or not.
I was working with the ECO setting to put my computer to sleep after certain amount of time. Once it was asleep for a certain amount of time, it would go into a shutdown/hibernation mode. It turns back on in the state that it was in when it went to sleep.
Also, if I have a program running and lock the computer, it will act like this as well when there is sleep time set.
I thought that I would be able to lock my computer and run a download over-night, but when I went to my computer in the morning, my computer was shutdown/hibernating. It came back up to where it was, but it appears that it hadn't continued the download for much over an hour before shutting down.
I don't think that this is intended, but I may be wrong.
I'm still digging around trying to find settings in regards to this. But I have hibernate turned completely off.
Is there some way to set the computer so that it won't shutdown/hibernate when in sleep mode and/or a locked screen?
In the meantime, I'm trying setting the ECO settings to "Sleep :: Never" to try to accomplish my download without the computer shutting down/hibernating during the process.

Thanks tjk.

Mac book air mid 2013, warms to approx 65 degrees when in sleep mode for 2 to 3 hrs?

Hello,
I have recently noticed that my macbook air mid 2013 warms up to approx 65 degs when in sleep mode for 2 hours or when I am doing my normal work. I am running Mevricks and I also use a moshi key board cover. Is it a cause of concern??

The keys without covers already transfer to a small degree finger oil to the LCD screen of the Air, even the thinnest keyboard covers place pressure on the LCD, however normally this would have no bearing unless stowed away in a pack with pressure, nevertheless causing dirt and oils is increased with covers to transfer more to the LCD, ....Macbook Air as well.
Beware of keyboard covers and using same
Beware of using thick keyboard covers on your Macbook, some pretty ones sold online are rather thick and upon closing your monitor, touch the screen and transfer more finger/hand oil to the LCD but at worst press excessively on the LCD display, especially in the case of the Air and newest Macbook Pro Retina. There is ultimately very little purposeful use of these keyboard covers if you keep your hands clean, additionally they do not protect against spills as many people presume they do; directly yes, but at the edges no. They also making typing a more challenging experience and run a fine line between 'serves no purpose' and 'possibly damaging'.
Screen covers protect against nothing and place an unwanted layer between the LCD and viewing, additionally if you dont touch same or dont have any pets that might claw at the screen there is no logical reason to have a screen shield.
dust will accumulate regardless. Realistically what are you trying to protect the screen from. The back is solid aluminum alloy, the front LCD viewing screen should never be intentionally touched.
outside of a sneeze or some debris which an extremely lightly damp cloth can remove, all else is dust. ...
Use a soft paintbrush or makeup brush for cleaning
One very useful tool for cleaning dust from the LCD screen, the hinge area of your notebook and around the keyboard, is a very soft inexpensive small paintbrush or a makeup brush. The less you wipe your LCD screen with anything like a cloth, the better. This small brush is very handy, quick, and ideal for removing dust from around and on your notebook.

Any helpful suggestion is appreciated.
