Internet not working after MAC book goes into sleep mode

If my mac book goes to sleep or if i close it when i wake it up/open it the internet doesnt work, usually have to restart it or wait several minutes in order for the internet to come back any way to fix this problem?

Safari, Firefox will all open up; we're talking specifically about airport. It will not automatically connect to my home's wireless network once I wake it from sleep. Actually it will not even pick up or recognize any other close by networks. When you click on the airport symbol to get the drop down menu, the only option that is there is 'other'.
Once I wake it, I will leave it there for about ten minutes and when I come back it has finally picked up the other networks and I am able to connect to my home's wireless network.

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).

Wireless not working after laptop wakes up from sleep mode

After my laptop wakes up from sleep, the wireless network stops. Even when the wireless is enabled, it is unable to scan the wireless networks. In order to make it working again, I have to restart my laptop. Here are some of the details that might be useful.

Well, the above two links have the problem similar to mine but not exactly. In first one there is a problem with network manager - that it is unable to restart after coming from sleep mode while that is not a problem in my case and I tried all the solutions provided in the second link, but didn't work.
What I figured is when I execute '#pm-suspend' and then close the lid. Then, after I open the lid I wireless works fine. 'pm-suspend' is not invoked if I close the lid. So I needed to invoke the above command when an acpi event is generated when I close the lid. So here is what I added in the /etc/acpi/handler.sh file
button/lid)
case "$3" in
close)
(sudo /usr/sbin/pm-suspend) #added
open)
This works fine for now. Still, I don't know why this solution works - Why executing pm-suspend solves my problem?

Good Morning:
Having an issue with my Hp Pavilion Elite HPE-541F and Monitor HP2311x
Yesterday, thinking I was updating Java ... clicked on it and agreed to things being allowed on computer ... started adding icons to my desktop .... then pop ups kept coming up to register etc ... I assumed that something was wrong so I attempted to restore system to previous ... since then my system will not boot up ... will say "starting windows" and I can hear the fans working but thats it ... second part of the issue is that the monitor keeps going to sleep, so even if I try to restart the computer in "safe" mode or anything else monitor goes to sleep and there's nothing on the screen so don't know if anything is doing anything .... Very sorry I'm also not very tech savy with computers ... just trying to save time and money before I have to bring system to computer repair person .... Any help would be appreciated .... Thanks so very much

HP Officejet 4620 All-in-One Loses Connection to Wireless Network When It Goes Into Sleep Mode

My HP 4620 All-In-One wireless printer works fine until it goes into sleep mode. Once it goes into sleep mode, it doesn't wake up if a print job is sent to it. If I wake it up manually by pressing the blinking on/off button, it still doesn't print. If I completely turn it off and then on again, the print job that was queued on my computer will start printing, but that's a huge pain and waste of time nearly every time I want to print. I've installed all available updates. I also assigned a static IP address in an effort to correct this but nothing helps. I see that others have complained about this problem, but I do not see that anyone has had success resolving this. My operating system is Windows Vista. I use a Link-Sys Wireless G Router. Thanks.
This question was solved.
View Solution.

so I have called HP tech support 12 times over the last 6 weeks and still my HP Officejet 4620 loses connection overnight. Of course becasue it was a birthday present I spent more time than I normally would have on this issue. While the tech are very polite they have not fixed my problem and now it is too late to return printer to store. This is a lot of money wasted and I think they need to admit this is a bug in this printer and resolve the problem!!!!!

Internet not working after turning Airport on

Hello,
All of a sudden, I can not connect to the internet when I turn the Airport on. The signal looks strong. But when I open my browser, it gives an error page. On a cafe where there is a free wireless internet that I go to often and had no problems connecting, gave me this message recently.
IP Configuration
192.168.1.46 in use by 00:18:39:88:81:fc, DHCP Server 192.168.1.1
Is there anything that I need to update in my Airport settings? If so, where? I have been trying to look for that and don't seem to have any luck.
Thanks for any help.

Mac Pro randomly goes into sleep mode

My (mid 2010) Mac Pro, OS X.6.8, randomly goes into sleep mode and I can't wake it, have to power it off and reboot. Just started to the best of my knowledge Friday (Jan 6, 2012) I've had it happen surfing the web in Safari, while working on an illustration in Adobe Illustrator, while running Apple Hardware Test, using 23" LCD connected by HDMI and DVI-D, Disconnected monitor and connected 12" Cintiq (LCD Tablet).
The monitor goes black, says "there's no signal coming from your computer", none of the keys will wake it. I have to hold down the power button until it turns off then power it back up. The time between the sleeps varies, 38min, 1hr 34min, 5min, 2hr 17min, 12min, etc. I disconnected everything (except keyboard, mouse, monitor) still the same. Opened and removed the ATI Radeon HD 5870, and noticed the PRAM battery, replaced it with a new one, thought that fixed it, worked for a long time then it happened again.
Tried Apple Hardware Tester again, it said everything is fine, ran it again an error popped up: 4SNS/1/40000000:Te1S-99.364, wrote it down then it slept.

The next time this happens open your mac and see if there is still a fan running. If so you are not sleeping, you are in a thermal cutoff. Keep you mac cover off.
Now reboot as you always do. Take a look at the fan in your 5870. Is it spinning? If so, try to keep an eye on it and see if you can "catch" it not spinning.
When the fan doesn't start, or if it does then stops, the card will overheat and the machine will go into thermal cutoff. The amount of time is variable.
I speak from experience. I am currently on my third 5870 video card. Both the previous two had this fan problem. The only wrinkle in my theory for you is that I wouldn't expect more that, say, 15 minutes of up time at the most, not hours like you got. But it may be that your card is starting ok, but stops sometime later. I chalk it up to the lousy fans Nvidia uses in the 5x70 cards.
FWIW, if you happen to catch the fan stopped before the machine goes into thermal cutoff you can give it a little nudge with your finger to get it going again.
I recommend one of the various temperature monitors. I use iStat Menus and display some key temps in my menu bar. Of course after going through two of these cards I am a bit paranoid!
Some other temperature monitors:
iStat Pro
Temperature Monitor
Hardware Monitor
Note, after typing all this I also realized you got a AHT 4SNS error. I would run AHT again to see if you get that error again. If so that means "Check Main Logic Board" and you may have a more serious hardware problem than just a video card! So my other recommendation is that when you machine fails again look inside for any lit diagnostic leds. There's some near the dimms but there are others on the board as well.

Mini goes into sleep mode after login on

I put my mini into sleep mode after logging out. Then, when I log back in, after a few seconds, it goes into sleep mode again. I have to re-awaken it.
This is not the way the computer should work.
Is this a configuration issue, any ideas????
I use Apple's bluetooth wireless keyboard and mouse combination.
Thanks

It sounds obvious but are you sure your power adapter is ok and the battery is charged. The behaviour sounds a lot like low battery sleep.
Press the check button on your battery pack - do you get plenty of lights?

Mac Tower Pro 10.8.5 keeps going into sleep mode

Purchased from Apple, refurbished 2012 Mac Tower Pro. At the same time, purchased a new Dell U2713HM, 27" monitor.
Have been operating on this new system since about the first week of December 2013.
Issue:
The computer has constantly gone into sleep mode after a few minutes of no activity. I can have iTunes radio playing, but the system still goes into sleep mode. As I am typing and moving the curser, the machine stays awake.
This has caused much frustration because when it goes into auto sleep mode, it quits all programs that I am in, and when it does this, I lose all the work I had accomplished. It litterally closes everything and goes to sleep in about 2-3 minutes of no activity.
BTW: the computer and monitor have all its new OEM cables that came in the box, when I purchased the units.
Solutions attempted:
System Preferences — Energy Saver: computer sleep and display sleep set to "never" and unclicked the box "Put hard disks to sleep when possible."
Dell settings: Turned off all energy savers.
Results:
Nothing. Problem persists.

I apologize for the angst. The problem has cost too much money in lost time and material because when it would automatically shut down after a few minutes, all my work was lost.
I misunderstood the terms of the warranty. Thank you for your input and patience. Much appreciated. For the benefit of others that experience this with a new Mac that auto shuts down. Check the following:
1. Go to System Preferences.
2. Click on Security and Privacy.
3. Click on Advanced (bottom right corner)
4. If the first line is checked (Log out after 5 minutes of inactivity); uncheck it and then click OK button.
5. Be sure to click the lock before existing Security and Privacy.
Now the machine will cease shutting down programs to go into sleep mode as soon as machine is inactive for a few minutes.

Streaming audio from my IPAD to my Apple TV from Rhapsody application. when Apple TV go into Screen Saver mode, about 5 minutes after that it stops playing the Audio Stream and goes into Sleep mode.

I am Streaming audio from my IPAD to my Apple TV from Rhapsody application. when Apple TV go into Screen Saver mode, about 5 minutes after that it stops playing the Audio Stream and goes into Sleep mode. I am using the Optical Out from the Apple TV to my receiver, the Apple TV is hard Wired to the Network, the IPAD is Wirelessly attached to the network (it continues to play the Audio Stream). When the Apple TV is turned back on it resumes playing once I manual select it for output from the IPAD. All device are on current releases of software. I have no Video hooked up to the Apple TV. How do I correct this?

Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.

What do I do if an iPod shuts down after going into sleep mode

My friends iPod keeps shutting down after it goes into sleep mode. I just fixed it up (restored it, had to dry it out after it fell into water) and now it does that. Everything else works fine but if I put it in sleep mode or put it into sleep mode it shuts down. How do I fix this because I've never seen this happen before.

Hey Tecmo_SB_Guy,
I would suggest you take a look at advanced power settings. It can seem like the notebook is turning off when it is actually just hibernating. You can set it to not hibernate.
1. Windows key + Q to open the Search Bar
2. Type "power"
3. Click Settings under the Search Bar
4. Select Power Options from the results on the left.
5. In Power Options, Click Change when the computer sleeps, on the left.
6. Set the Put the computer to sleep setting so that it fits your usage best.
7. Click Change advanced power settings, at the bottom.
8. Expand Sleep and expand Hibernate after. If you want you can change the hibernation setting to Never by typing "Never" into the minutes field. See attached picture. You can do this for battery and/or plugged in.
9. Click Apply to save changes.
If you don't already shut it down periodically, I would suggest shutting it down at least 2-3 times a week if you use it daily. Leaving the computer running continuously can shorten its lifespan. Hard drive failures and motherboard issues are seen much more often on machines that are left running constantly. Computers get bogged down and run slowly when the memory is full. Memory only clears out and resets itself when the computer is shut down. Here is a link explaining more about memory accumulation and hardware aging.
I hope these suggestions help! Please let me know if you have any questions

Mac goes into sleep mode amd doesnt come out!!!!!!!

Hi, new to this so sorry if this is a dum question. I have installed Snow Leopard on my IMac and Air. No prob on the Air but probs with the IMac. Everytime it goes into sleep mode I get a black blank screen and it wont come back up? have to reboot everytime or leave front row on with a slide show! any ideas welcome?

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.

Late 2012 Mac mini with OSX 10.8.2 has started shutting down instead of going into sleep mode.

Sometime in the last week or so my mac mini has started going into full shut down instead of sleep mode.
I have tried checking and unchecking energy saver boxes but haven't found anything which will get me back to where I used to be - and I haven't knowingly changed anything to make this happen.- maybe an OS update caused it?
The machine will fire up with a tablet click rather than needing the reset button to be pushed so clearly the machine is sort of halfway between sleep and full 'off'. Most frustrating as one of the key issues for me in getting this my first mac was its easy sleep and super quick fire up compared to windows.
Any help appreciated
Oh yes I just remembered that I did just install 2 8gb of crucial RAM (to replace the supplied 2 2gb but surely that can't have anything to do with it - can it)?

Adding to my first post I can now advise that when the mac goes into sleep mode the light on the front stays on (it does not pulse so clearly it is not really sleeping).
When i click the tablet / keyboard this is actually what triggers the mac to reboot
I have tried resetting the SMC as per the following link to no avail

Help please!
