Upon waking from sleep, laptop will not reconnect to wireless net.

If my laptop is on and I'm using it and I close it to put it away for a bit, when I come back to open it, it doesn't reconnect to the internet all the time.
I have to restart the computer in order to get it to reconnect to my wireless net. Just wondering if anyone knows what's going on.
Thanks!

besides setting the network as preffered and in the network settings udner the options for airport make sure it will connect to any available network, there isnt much else to do
some times it jus takes 30-60 seconds, also check that the network is paired to the location (if you have separate locations)

After waking from Sleep it won't recogize the wireless router

My mother has my old ibook G3 600 mhz late 2001 ibook, with the old airport card. It is over 5 years old. She just upgraded to 10.4.5 and now when she wakes it from sleep it will not recognize the wireless router. I know the router and the connection are fine because my other ibook picks it up fine.
Here the wierd thing - when I restart the ibook it recognizes the signal, connects , and works perfectly until it is put to sleep. As soon as it is woken up again, you can't even find the wireless router in the pull down menu. I don't think the airport card is bad because it works perfectly when first started.
Any suggestions ?
Thanks in advance for your help!

Hi.
Welcome to Apple Discussions
So does your iBook still pick it up when she can't? Put all of yours to sleep and then see if they all pick the router up. What router do you have? You might want to post this in corresponding Airport Forum because a lot of more (specifically) wireless knowledgeable people "hang out" there. There also may be people with the same problem that can help you.

Black screen upon waking from sleep

Hello,
I have an intermittent problem with waking my entry-level MBP from sleep; on some occasions, the screen remains black instead of the system waking up and displaying the Finder.
Recently, upon waking from sleep, the authentication dialog displayed, I typed my password and pressed return, the dialog dismissed, the screen remained black, and the wait cursor displayed without spinning.
To recover, I needed to force power down and cold reboot.
system.log (in Console) contained the following entry at the time of the crash.
Aug 14 07:39:51 BF-H-MBP kernel[0]: NVChannel(GL): Graphics channel exception! status = 0xffff info32 = 0xd = GR: SW Notify ErrorAug 14 07:39:51 BF-H-MBP kernel[0]: NVChannel(GL): Graphics channel exception! status = 0xffff info32 = 0xd = GR: SW Notify Error
The entries surrounding the one above were as follows (the next to last one evidently was the final entry before the forced power down).

Can someone diagnose the problem based upon the above Console entries?
Thanks in advance!

Hi,
Thanks for taking time to post.
My question is different than the one your posting answers.
My question is, what is the diagnosis of the problem based upon the Console log entries that I've posted (rather than "How do I recover from the black screen?")?
Cheers!

User Name Upon Waking from Sleep

Hey guys,
We're given the choice of entering a password upon waking from sleep. I kinda want to take it one step further and have the user name erased too so that people have to enter the user name and the password upon the computer waking. Does anyone know how to do this or if it's even possible?
Thanks for any help.

The only way I can think of would be to log out rather than just put it to sleep or let it go to sleep. However, if you have a good secure password there really isn't too much reason to require the additional step.
There may be a way to do it but I can't think of one.

Mac Pro will not shut down, wakes from sleep and will not start up in safe mode (restarts).

Wakes from sleep about every 4.5 mins, here is the log from wake from sleep:

Hi, this log has some similarities to my ipod touch which seems to be not sleeping properly due to wireless issues. Can I check - are you using a wifi connection - if so have you tried ethernet?

Sluggish upon waking from sleep

when I wake my Mac Book Pro from sleep, my mouse reacts strangely (erratically, sluggishly, etc) for a good 30 seconds. Anyone experience anything similar? Thanks.

Not sure if you've fixed this issue already, but are you using the iStat Pro widget by any chance? I was experiencing the exact same problem (erratic mouse behaviour after waking from sleep), and it was resolved when I removed the iStat Pro widget.
Not to cast aspersions on this particular widget or anything, but removing it seemed to resolve the issue for me.

Finder opens to iDisk upon waking from sleep/opening lid

Every time I open the lid on my 17" G4, finder pops up and idisk is selected. Not really a problem, I guess, however, it is rather annoying. I don't recall making any changes.

try maybe -
system prefs> energy saver> and deselect 'wake this computer when a modem is detetected' something like that - deselect all internet type waking settings.
or open up idisc> prefrences> and there may be a wake from sleep setting somewhere (not used idisc myself)

Bizarre psychedelic display upon waking from sleep

does this mean a logic board failure is imminent? the screen showed nothing but a bizarre, seemingly random collection of pixels in all colors - almost like multicolored tv 'snow.'
I ran the hardware test disk, and it said the logic board 'passed,' but i'm not sure how it can test whether or not it's seated correctly.
in any case, i've also been experiencing other display issues (black screen, typically), most commonly when waking from sleep.
this is my wife's computer, by the way, and it's a desktop replacement - no travel, so it hasn't been abused at all.

Does an attached external display show the same effects
as the internal one? The supplied adapter should allow
a second display to mirror the internal one, and this may
help troubleshoot the extent of the hardware failure.

When waking up my macbook air from sleep, display will not turn back on.

My mid 2011 macbook air running lion is having some issues. The display, after the laptop has been woken up from sleep, will not come back on. The rest of the computer is fully functional as when i press the volume keys, i can hear the sound that it makes, the keyboard brightness keys also work. Theonly way i can fix this at the moment is doing a force shutdown and turning it back on again. If anyone has an answer to this it would be greatly appreciated.
Thanks.

Having much the same problem with my 2011 11" Air, running 10.8.2 and wondering if you ever got any resolution on this. I've had the same issues through several versions of Mountain Lion.
My display does come up, but what I see is my login screen (I have it set to require a password on wake), but with a beachball, and I can't type in the password field. I can tell that other processes are running (for instance, just now I could hear a YouTube video playing) but I can't make it respond to input.
I've also had times where I put it to sleep by closing the lid, only to come back some time later to hear the fan running and everything unresponsive.
I've reset the PRAM, reinstalled Mountain Lion, reset the SMC. I'm purposely not running a lot of extra software.
Just curious, are you using FileVault at all?

Fingerprint Reader not working upon waking from sleep for windows login

Hello,
I have a brand new T540P with a Validity fingerprint reader.
Rougly 80% of the time, the Fingerprint reader is unresponsive at the windows login screen after waking the computer from sleep. It works 100% of the time when booting from an off position, however. Once logged in, it also works 100% of the time. The issue only arises when logging into windows.
Things I have tried
-uninstalling/installing device in device manager and finger print manager pro software
-setting fingerprints through both fingerprint manager pro software (lenovo) OR through the built in windows fingerprint control panel options
-disabling "allow windows to turn off this device to save power" in device manager.
I should note as well that I have another T540P that I ordered as a replacement. Both models experience the same issue.
Is this a platform wide issue affecting all T540P models? This is frusterating.
Solved!

Your report is the first we have ever heard of this issue on T/W. It does not happen on my T/W systems here (with or without 30 Day Standby enabled). The other reports I heard of this problem came from X240.
I just want to confirm with you - the problem happens after coming out of Sleep (and not Hibernate), right?
Can you tell me exactly what you are doing? e.g.
1. Use the computer normally (is AC attached or not?)
2. Close the lid - the computer goes to sleep (or do you go to sleep some other way?)
3. Open the lid 2 hours later (or how long)?
4. are you using a dock?
The more info you can provide, the better. Thanks for your help.
Also please let me know what BIOS version you have.

MacPro Freezes upon waking from sleep

I have had my macpro for almost a year and have never had this problem. I have not connected any new peripherals to it or done anything new that I can think of. I have tried sleep and wake with them all disconnected, but still no luck.
Upon waking the computer comes back to life, however, the cursor does not move, and key commands also will not work. Only way to get it back to life is a hard restart. This began only a week ago, and was prior to the newest EFI Firmware update.
Is power consumption related to this possibly? Not enough juice to get her back online? or do I need to get her some coffee?

If it has too much equipment on the same circuit it can be a problem.
The freeze alone is enough to result in a corrupt directory.
Freezes on wake from sleep can be as simple as a bad USB cable.

What causes spinning beach ball upon waking from sleep

I have a 4 year old iMac that has recently developed an intermittent problem. If I put it to sleep, sometimes on waking up, the hard drive access seems to stop. I hear a tap sound as though it was trying to read the disk, but it gets stuck and a spinning beach ball appears instead of the cursor. I can move it around, but I cannot perform any actions. The ball will stay forever if I let it.
Another variation occurs shortly after wake-up, where I start to click on a file on the desktop or even an icon in the Dock. The name will become highlighted and then the same spinning beach ball appears.
The only cure for the behavior has been to shut it down and reboot. It then works fine.
The weird thing is that I have just been using it for 6 hours straight with out any hassles... until I will put it to sleep!
I have tried running Disk Utility from the Leopard System Disk as well as repairing permissions and I have used Disk Warrior 4 . It seemed to allow about 6-8 sleep cycles before the symptoms re-appeared.
I verified the disk and repaired the permissions again yesterday and all seemed OK. Yet today, when I started up from sleep. the system froze. The only cure so far is to never allow the hard drive to sleep. I put the display to sleep after 15 minutes but the hard drive continues to spin.
I am concerned that not sleeping the hard drive will do harm to it.
I am using OS 10.5.8 on a 233 Ghz Core 2 Duo iMac
I have Parallels 4 installed and cannot tell you if the problems started after a PC session.

HI Studio Guy,
Welcome to the forums. When ever your having trouble with a computer; it's really a good idea to back every thing up. If your not backing up; http://support.apple.com/kb/ht1427 explains how to back up your computer to an external hard drive. (assuming your using 10.5 or 10.6)
You could try running a hardware test on the computer. http://support.apple.com/kb/ht1509
You could try a safeboot, it can repair lots of issues. http://support.apple.com/kb/ht1455
This article explains how to delete the sleep image; a bad sleep image can cause wake from sleep issues. http://osxdaily.com/2010/10/11/sleepimage-mac/
But if your hard drive is rapidly making a taping noise you may want to take it to a genius bar; they might recommend replacing the hard drive. http://www.apple.com/retail/geniusbar/

No recognition of external LED projectors upon waking from sleep.

For many, many years, I simply plugged my MBP while it was asleep, turned on the projector, woke the computer from sleep, and the computer would recognize the projector (and the projector would recognize the computer...). This worked in any of the classrooms.
Since "upgrading" to Mavericks, this sequence does not work. The computer wakes, but does not recognize the projector. The projector does not "see" the computer. The only way I get them to communicate is to restart the computer. This has been taking up valuable lecture time at the beginning of every class. Upon restart and opening up Keynote, the files I had open don't automatically come up - i.e., I have to reopen those files from the finder as if they had not been open previously.
I've tried this in three different lecture rooms, each of which gave me no troubles before. The only difference is Mavericks. Any help?

Of course I meant VGA, not LED. Sorry!

Freezing upon waking from sleep mode

I'm having a freeze issue with my imac. When I go to wake it up from sleep mode it wakes up, but then immediately freezes. Sometimes the dock items will still magnify, sometimes not. Sometimes the whole system will eventually wake up and open whatever program I was trying to open, but it takes upwards of half an hour. I used the techtool disc and it showed no hardware issues. Any help would be greatly appreciated.

Please try resetting the PRAM

and also the SMC

2014 Mac Mini connected to Samsung s22b310b monitor colors bad upon waking from sleep.

Occasionally when I wake the 2014 Mac mini from sleep the colors on the monitor are very bright. I go into systems preferences and then display. I click on the color button and it will change back to normal. I have tried both a DVI to mini displayport and VGA to mini displayport. Problem occurs with both. What else can I try to prevent this from happening?
