Wi-Fi error after waking from Sleep Mode.

Hello guys,
1 Week ago, I went to a friends house, and while I was on the car I forgot to turn off the Wi-Fi / disconnect from mine once I got outside my house. After doing this, when I got back home, and for 4 days in a row, when I turn my MBP on from Sleep, the Wi-Fi icon appears with an Exclamation Sign (Pic below). To fix this I must each time go to System Preferences > Network > Change location in the top bar > Click Apply, otherwise it won't connect, so it's very stressful each time having 2 do this. If anybody could help me fix it as it was before (I didn't need to do any of this before).
Thanks!

Forget it, I solved the problem; I went to Advanced Options, then selected my network and deleted it, then I clicked Apply. I turned Wi-Fi off, then I turned it back on, then join my network, drag it to the top of the preference network list in Advanced Options, and now everything seems to be back to normal .
Hope this helps anybody having the same issue.

Kernel Panic Error after waking from sleep mode

My MacBook Air (5.2) was purchased in February and has been back to the Genius Bar twice to try to identify the issue causing the kernel panic error that occurs after the computer is placed in sleep mode (running on battery or AC). GB was unable to reproduce the errors when the laptop was left overnight during it's most recent visit (4/18/13). This leads me to believe it's related to my wireless router/printer drivers. Very frustrating and I'm just about ready to turn this back into Apple since I'm wasting more time trouble-shooting than enjoying the computer!

- Is this a reasonable suspect causing my daily (or more) kernel panics?
- How do I remove it?

The third-party system modification "SX-Virtual Link" may be contributing to your problem. I suggest you back up all data, then uninstall it according to the developer's instructions. Reboot and see whether there's any improvement.

Black screen after waking from sleep mode - Compaq Presario CQ5110F

My mother's computer has been having the problem listed in the subject -- after waking from sleep mode, the monitor just stays black, and won't come back. After trying everything I could find online, I eventually found the bios update which claims to fix the exact issue. The problem is that I guess my mother had opted to upgrade to Windows 7, while the bios update seems to only work for Windows Vista, as I get the following error message: "Your system does not meet the minimum requirements for this update. Update has been canceleld. (9998)." I've tried running the update in Vista compatibility mode, with no luck. I've tried using a different monitor, I've updated all the drivers, Windows Updates are all current, I've cleared CMOS. Any idea on how to fix this? It's very recent; only for about the past 2 weeks has this been happening, while we've had the computer for over 3 years. It's quite a waste of energy to keep it on all day.

Hello liltwix,
When taking your computer out of safe mode the screen just remains black, is that correct? I will try to help you with this issue.
I understand you upgraded from Vista to 7, was that when the issue started or has the computer had windows 7 installed for some time before this problem started?
Please respond back at your earliest convenience.
Thanks

Freeze after waking from sleep mode on MBP retina

After waking from sleep mode my MBP retina freezes for 3-5 seconds. Mouse and touchpad don't work. I wonder if it's mountain lion problem or hardware problem. Anyone faced this?

Just got a brand new model and OS X 10.8.2 (12C3012) and face the same issue, almost everytime it sleeps for too long. This is not a 3rd type SDD, this is a standard Apple SSD. I turned off the BT, I removed the almost every option from the battery saver mode. The current test is to disable the power nap - I will let you all know the result in a few hours.

My zero Key isn't working after waking from sleep mode. This is a real problem for me because my password contains a zero

My zero Key isn't working after waking from sleep mode. This is a real problem for me because my password contains a zero. I don't recall spilling anything or jamming it just that it worked before I closed the computer and wasn't after I woke it up.
I would like to fix the key but if that's not possible right away , Is there a way to reset my password without being able to type with a key thats in it?

Start by swapping the keyboard. You don't need to spend a fortune, and handy to have spare. USB cables can be bad even new.
When I had some problems Apple wanted to blame the mouse, keyboard, cable, but in the end I found
A. run Disk Warrior
B. Corrupt pref or conflict with version of Hardware Monitor and other background tasks

My MacBook Pro won't reconnect to my Wi-FI automatically after waking from sleep mode

Hello, everyone. Since I updated to Yosemite, my MacBook Pro won't reconnect to my Wi-FI automatically after waking from sleep mode.
Does anyone know how to fix that?
Thanks in advance,
Arthur.

Hi, arthurpacifico.
Thank you for visiting Apple Support Communities.
Here are a couple troubleshooting steps that I would recommend trying to see if it corrects this issue.
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/HT3964
Reset your computer’s PRAM
http://support.apple.com/kb/HT1379
If the issue persists, try the troubleshooting steps I have attached below.
Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
After waking from sleep or starting up, your computer may not show that it is connected to a Wi-Fi network.
After start or wake, your computer may indicate that it is connected to a network, but does not connect to the Internet.
Solution
Use these steps if your computer does not automatically connect to your desired Wi-Fi network.
Check your TCP/IP settings in the Network pane of the System Preferences. Click the "Renew DHCP lease" button
Choose System Preferences from the Apple menu.
Choose Network from the View menu.
Select Wi-Fi, then click the Advanced button in the lower-left hand corner of the screen.
Click the TCP/IP tab from the top of the screen.
Click the "Renew DHCP lease" button.
Select the Wi-Fi tab and view your Preferred Networks list.
Select each network and click the minus sign to remove those networks from your Preferred Networks list.
Click OK and close the Network preferences.
Remove your stored network passwords using the Keychain Access Utility.Restart your computer.
Open Keychain Access from /Applications/Utilities. Your window will look like this:
Remove your AirPort network passwords from the login keychain: Select the "login" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".
Remove your AirPort network passwords from the System keychain: Select the "System" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".
Note: The above steps will remove your Wi-Fi network passwords. If you do not know them, or if your network does not use passwords to restrict access, you should contact your network administrator.
Join your Wi-Fi network. You will need to enter your password for your network again if it requires one.

Satellite A660-18N - Powers off after waking from sleep mode

My Satellite A660-18N powers off 2-3 seconds after waking from sleep mode. I upgraded the memory from 4GB to 8GB, using Crucial's website, so I know it's compatible. BIOS is updated to 2.00.
Not sure what to do, how can I fix this without turning off Sleep mode completely?

Hello
>Currently I've turned off sleep mode altogether. I've also reset the BIOS settings from the boot menu but it hasn't fixed the problem
And why you dont test it with pretested memory modules from an authorized service provider? The part number for such RAM is PA3677U-1M4G. Its one 4GB DDR3-1066 MHz memory module.
Furthermore it would be interesting to know who says that Crucial memory is compatible Maybe its compatible to other Toshiba notebooks but fact is you have problems after waking from sleep mode and this happens only with Crucial memory and not with preinstalled modules.
I dont think somebody here can provide you a solution for this because its just a compatibility issue and its user to user forum only.

My desktop background disappears after waking from sleep mode

My desktop backgroung disappears after waking from sleep mode. Just converted to Lion.

I spoke with Tech Support this morning. Apparently this is a known issue with Lion. I found it interesting that the rep insisted on saying that "it is the way Lion functions" instead of admitting that it is a GLITCH in the programming. He even said that it happens randomly and not on all computers and not all users experience this. That ought to tell you that it's a glitch. Anyway, there is a "workaround" which is what you do to put a bandage on a persistent wound that should really get surgically stitched:
You either have to log out every time you leave the laptop, or you have to change Energy saver preference to set the display to go to sleep AFTER the computer is set to log out (in Security preferences).
Here is the article that instructs us on applying the bandage::

Suffice it to say that Apple does not plan on stitching this one up any time soon..

Dark screen remains after waking from sleep mode

Whilst using Safari Version 3.1.2, Mac OS 10.4.11 on my Powerbook G4 (aluminum, 1.5 ghz), my screen remains dark upon waking from sleep mode. Trying to increase screen brightness is ineffectual for some reason likely related to this problem. My only workaround is to force shutdown and restart. Any ideas about a solution would be greatly appreciated.

Hi Gary,
This behavior is not a Safari issue but system related.
Close all applications an run in utilities> disc repair permissions.
After you done reboot an see what happens when your Mac gets to sleep mode again. This time don't open any applications to test it. Just leave it showing your desktop.

SMB shares die after waking from sleep mode

When my Macbook is freshly booted, I can access the SMB shares on my linux server just fine. The fun starts when the computer is put to sleep and then awakened. About 50% of the time, the shares on my server are inaccessible after waking from sleep. When I click on the server in the Finder, it just says it's connecting and sits there. Not only are the shares inaccessible, but the server cannot be "ejected" (Item in use). Plus, the system cannot be rebooted nicely. It just hangs with the spinning wheel until I ctrlcommandreset the thing. Other services on the server remain accessible from the Macbook after samba dies (iTunes library, FTP). Occasionally, the shares will come to life if I sleep/wake the computer again, but that is rare.
Tiger worked fine with the same server, it wasn't until the 10.5 upgrade that I began having trouble. I called Apple tech support about the issue, and waited 2 weeks for them to tell me to "install Bonjour on the server." I have formatted and reinstalled Leopard more times than I care to count, but the problem always remains. I've been dealing with this for almost a YEAR now and am totally desperate for a solution. Has anybody ever heard of this before?? The server is running Clarkconnect (Centos derivative).

My iMac won't automatically connect to wifi after waking from sleep mode

After dowloading the newest software update and performing a firmware update for my Airport router, my Imac won't connect to Wifi automatically after waking from sleep mode

Please re-download and install the 10.7.3 update. You can locate it at 10.7.3 (Client Combo). Follow the on-screen instructions. Then test it out, if you still have the same problem please restart, when you hear the startup tone hold down the Option Key and then choose the Recovery Partition. Then open Disk Utilities and Repair Disk Permissions 2x. Then exit DU, restart normally and re-test.

Anyone's MacPro have problems after waking from sleep mode?

After waking from sleep, my MacPro 2x2.4 Quadcore Intel Xeon freezes in several applications that had been running before sleeping. Mail and Firefox both get into endless loops trying to download data and will not force quit. Pulldown restart and shut down do not function when this is occurring. Must shuyt down manually from box and start again. Everything works fine again until it goes to sleep again.

Start by swapping the keyboard. You don't need to spend a fortune, and handy to have spare. USB cables can be bad even new.
When I had some problems Apple wanted to blame the mouse, keyboard, cable, but in the end I found
A. run Disk Warrior
B. Corrupt pref or conflict with version of Hardware Monitor and other background tasks

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!

Programs freeze after waking from sleep mode

For some reason if I put my MBP into sleep mode (10.6.3), any programs I try to start up will freeze (I would to force quit since nothing opens). Any programs that were open prior to going into sleep mode working fine, unless quit it and then try to restart the program same problem (so if firefox open before sleep placed my laptop in sleep mode then I wake the laptop, firefox works fine. Now if I were to quit firefox after my laptop was turned on from sleep mode then I quit firefox and try to reopen it, then firefox icon just bounces up and down and nothing happens and it freeze and I have to force quit). The only way is for me restart the laptop, but even then its a temp fix.

Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk.
You could have some directory corruption. Let us know what errors Disk Utility reports and if DU was able to repair them. Disk Utility's Disk Repair is not perfect and may not find or repair all directory issues. A stronger utility may be required to finish the job.
After that Repair Permissions.
No need to report Permissions errors....we all get them.

Bizarre app behavior after waking from Sleep Mode

My iMac Core Duo runs like a top. It is fast and quiet. I have no problems with applications, both Universal and PowerPC. I maintain it with everything that I suggest others do in posts.
But, there is this one strange quirkiness that I have put off mentioning because I kept hoping that each new OS X update would address the issue. It has to do with waking my Mac from sleep mode with it logged into my user account. Not every time, but most of the time, if I put my Mac to sleep or it goes to sleep from inactivity while it is logged into my user account, I experience strange application behaviors upon waking.
For example, upon awaking Mail.app will contact my .Mac account and download any new mail that has arrived. But, if I try to open any of this mail, instead of opening, Mail.app will open a new outgoing email addressed to whomever sent me the mail I tried to open. Quitting and restarting does not solve this problem. Other apps demonstrate similar bizarre behavior. To only way to solve the issue is to log out and back into my user account.
However, if I log out of my user account and then put the Mac to sleep from the Login Manager I don't experience this issue. So at night I always log out before putting the Mac to sleep.
Anyone else experiencing similar issues? Any ideas on solving this? Do you think it is a bug in Universal Mac OS X?

Sorry this isn't a solution, rather is a commiseration. Often after my iMac wakes from sleep mode it refuses to see my internet connection. I have to unplug and reset my DSL modem to force the computer to see that it exists.
It sounds like the problem might be related, does anyone have any brilliant suggestions?
Thanks,
Lonnie
