Problems connecting to Monitor after waking up MacBook from sleep

Hi,
I am experiencing a lot of problems connecting my macbook pro to external monitor once I put it to sleep. I have tried every options like setting up PRAM and all, but it just wont work. Sometimes the restart works and sometimes it wont. I am using a Samsung monitor. I have no idea what to do, as I keep on clicking Detect displays and it just wont do anything. Can anybody please help me as to how I can wake up my macbook from sleep and get it connected to the monitor. I have a mac keyboard and bluetooth mouse, but neither would wake the mac. I have change my bluetooth settings so that the mouse should be able to wake it up..

1. Make sure the network is on the preferred list by following these instructions. It's important to read the article carefully, as it's the starting point for any further efforts to solve the problem. If you skip any of the steps, the problem may not be solved. Make sure the box marked
Remember networks this computer has joined
is checked.
2. Follow the instructions in this support article under the heading "Symptom: The network connection drops unexpectedly."
3. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
4. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.
5. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
6. Repair permissions on the startup volume.
7. Turn off Bluetooth and test.
8. Reset the System Management Controller.
9. Reset the PRAM.
10. Reinstall OS X.
Updating to 10.9.2 did the trick. So I thought. Does anyone have a solution?
Thanks!

What might my problem be if my display will not come on after waking the computer from sleep or powering it on?

When I try to wake the MBP from sleep (opening the lid, pressing spacebar, or pressing power button), the computer display doesn't come on. The light on the front shows it is awake but there is no display or backlight though the caps lock lights up. I have tried an SMC and PRAM reset to no avail. I tried to start up in safe mode but now as soon as the screen comes up to select the user the display goes out and I don't know how to get it to stop trying to boot up in safe mode. Any suggestions as to what the problem might be and some possible solutions?

Not detecting external display after waking up MBP from sleep mode

I am a recent owner of a MBP and enjoying it. However, one problem that I can't seem to find a solution to is the external display problem after sleep mode.
When I first boot up the Mac and plug in my Dell external monitor via the mini adapter, there is no problem with detection or display. However, every time I put the MBP in sleep mode and then wake it up again, the external monitor does not "wake" up and my MBP only displays my normal screen on the Mac.
I tried to 'Detect Displays' to no avail and the only solution is unplugging the mini connection and plugging it back into the MBP for the MBP to re-detect the external monitor.
Although this is a quick fix in itself, I do not want to wear out the mini port by doing this every timeI come out of sleep mode. Any solutions so that the external monitor will detect the MBP waking up from sleep and display properly? Thanks!

And same problem here.
Using a MBP 2.66 i7 with a Dell 3008WFP that's connected to the MBP through DisplayPort. It works some of the time but once in a while (only been using the new MBP for a couple of days now) the monitor won't come out of sleep mode. Turning it off/on causes OS X to completely ignore the monitor. I was able to get this setup to work again by pressing 'Detect Displays' in the System Preferences pane but most of the times that doesn't help. The only sure way to get the monitor working again is by booting into Windows through Bootcamp, Windows is able to use the monitor, if I reboot after that OS X sees the monitor again.
Also saw a magenta line/stripe on the left side of my monitor and the monitor sometimes makes a buzzing sound when connected to the MBP through DisplayPort. That's what you get by using bleeding edge tech I guess :\ Only alternative is buying the mini-DP to dual-DVI connector but paying $99 just to be able to use an external monitor is rather insane. Besides that lots of users are having problems with this adapter.

Can't connect via ethernet after iBook wakes up from sleep

I'm running 10.4.0 on a 1.33 GHz G4 iBook. Since buying the computer in 2005, I've been connecting to the internet in various locations via AirPort, though I have hooked my iBook up to ethernet connections in the past and had no problems.
Recently I moved to a university where I must connect via ethernet, as the wireless network doesn't extend to the areas where I do most of my work. I bought a new cable. Much of the time, my connection is fine. But frequently I am unable to connect to the internet at all via ethernet, and I've noticed that it's always after I've woken the computer up from sleep. I've tried various ridiculous "kick the car and maybe it will start" techniques like unplugging the cable at both ends and waiting, restarting five or six times in a row, etc., and it starts connecting eventually, but I have NO idea why or why not. When I check my network preferences, I get the message "Built-in Ethernet is currently active and has the IP address [xxx.xxx.x.xxx]. You are connected to the Internet via Built-In Ethernet." But I'm not. What's going on here?

Sorry, meant to indicate an IP address without giving the exact numbers, and it came up as an HTTP address. My network connections system preference panel indicates a normal IP address. (And it's not self-assigned.)

Internet connection not working after computer wakes up from sleep. OSX Lion

After upgrading to Lion, I noticed that my internet connection doesn't work when I wake my computer from sleep. I have to turn off the WiFi connection, turn it back on and it will work. I guess this is a glitch that will be fixed later on. Just wanted to point it out. I don't know if someone else is having the same problem? I am not very happy with the upgrade to Lion, things seem to be slower, I've had several freezes requiring to reboot. I guess Lion needed a little more twicking before release. Not worth the $29.99 price tag.

I had this problem on SL and on Lion as well, and it occures for WiFi and Ethernet connections.
In fact the internet connection was not broken as I could ping the destination usin the IP (not DNS name).
In this case the problem was related to mDNSResponder task which handles all dns queries.
It was the most frequent problem in my day to day work with SL and now Lion. It was never fixed by any patch from Apple. I tried almost all voodoo including fresh install, all possible config changes - no solution.
The only version with no problems related to network was 10.5.8. All the other versions had issues of different kind (WiFi instability (lost signal), DNS problems (for wireless and wired connection) sometimes associated with machine sleep and wake up and sometimes with no reason.
QUESTION: Is your problem independent of the access point / router you connect to.
I must say networking was (and still is) the weakest part, besides the other OS X weaknesses I experienced during 4 years of OS X usage.
No problems in the same network with Linux or Windows beeing ran natively on my iMac So hardware is OK.
Software is of poor quality. Not much more to say in this matter.
I found a very interesting article dated 1996 about programming which I think is still valid.

Problem Connecting to Internet after recent Software Updates from Apple

I have an old iMac 15" flat panel, running OS X 10.3.9, just ran the Software Update an hour ago. Now my computer won't connect to my wireless network via the Airport. I tried to open the Internet Connect apps from Apple and it won't even load, it has this swirling beachball has been on for 15 minutes and it says "Loading Internet Connect..."
Anybody experience something like this! Could this be another Apple blunder with their software update?
I tried, restart, remove the plist of Internet Connect, all those did not help!
Please help. Thanks

Try resetting Airport as per this article;

By the way, if your problem has not been solved then leave it as unanswered until such time it is, as you will get more responses.

How do I start up my computer when the screen is black after "waking" it up from sleep mode and/or turning it on from the shut down?

I really need help! I just got this MacBook Air almost two weeks ago. It is a refirbished one. Now lately, when I put it to sleep and then get back to it, it won't wake up. It just gives me a black screen and a running noise. Sometimes it does it too when I shut it down. And sometimes it will work fine as if it never happens-i move the mouse and the computer starts up. I am deaf and living on campus for school, so there is no chance for me to get some help through a simple phone call and there is no nearby apple stores or providers.
Please help me, I do not want to go back to my Dell computer.

I'm not certain but my new MBA 13...when in sleep mode comes back on from a black screen when I simply click on the left mouse button. Also, one time I did a SECURE EMPTY TRASH on files that totalled more than 1GB and it took so long that the fan kept increasing in speed so I pressed on the POWER button and the MBA shut...I was able to boot up with no problem. As a rule, I now only do secured erases for trash bin data totalling 500mb or less...anything above that gets a regular erase (dump).

Occasional reboot when waking MacBook from sleep. iTunes related?

Recently, sometimes when I'm waking my MacBook from sleeping, instead of waking, it reboots. I'd say, one out of twenty times.
It started around the same time I started subscribing to PodCasts. (I'm not using an iPod with them, just downloading them to the MacBook and listening to them through iTunes.)
My iTunes version is 7.0.2.
Any clue as to why this may be happening? Or, more importantly, how to resolve this issue?
MacBook Mac OS X (10.4.8)

Hi, sugapablo.
I wouldn't think your PodCast subscriptions are the cause. However, you could cancel your subscriptions for a few weeks and see if that sorts it out.
Here are some troubleshooting ideas that I think may be more relevant:
1. Have you applied the "MacBook SMC Firmware Update 1.1."? That update fixed a problem with <<a href="http://docs.info.apple.com/article.html?artnum=304308">spontaneous shutdowns — at a guess, your problem may be related.
2. You may want to try some of the troubleshooting steps cited in the following documents:• "http://docs.info.apple.com/article.html?artnum=303234."
• "Mac OS X: Why your Mac might not sleep or stay in sleep mode."
3. Run the Apple Hardware Test (AHT) that came the affected computer. See my "Apple Hardware Test" FAQ for comprehensive advice on using the AHT in troubleshooting.
4. You cited that it reboots. However, if you are seeing the following message
that indicates a kernel panic.
If so, see my "Resolving Kernel Panics" FAQ. This FAQ includes step-by-step instructions for identifying and resolving some of the most common causes of kernel panics. The FAQ is a roadmap: start at the beginning and work systematically through the end, i.e. the "If all else fails..." section.
5. You may want to search the "MacBook Discussion" for similar reports.
6. Since I suspect your MacBook is still under warranty, you may want to contact AppleCare
Good luck!

Trouble waking macbook from sleep

Im having trouble waking my macbook from sleep once i close the top of my computer. I can just make out the outline of my desktop but it is very dark. It takes around 4-5 minutes before the screen of the computer illuminates. I have tried holding down F2 as well as tapping the power button but neither seems to work. does anyone have any suggestions?

Same here. I did bring it in and they exchanged it but the new one is even worse. Once it gets into this cycle, I can get it to the login screen, it won't accept my password (even making SURE i enter it correctly) until the third time. Then it accepts it and bam, goes to sleep again. Only a hard reboot fixes it for a time. It happened this morning, so we'll see how long until it happens again. We have two other macbooks (a late 07 model and a macbook pro from early 08) that do not do this.

I have a password problem. After importing data and settings from one MacBook Pro to a new one, I have to put my iCloud password in when re-starting, but the password from the old computer in when waking the computer from sleep.

I have a password problem. After importing data and settings from one MacBook Pro to a new one, I have to put my iCloud password in when re-starting the new computer, but the password from the old computer in when waking the computer from sleep. I want to use my iCloud password on both computers consistently. How can I fix this?

The only other place to change a password for the computer login is in Users & Groups preferences. But I don't really know enough here to fix your problem. You can try fixing the keychain:
iCloud- Frequently asked questions about iCloud Keychain
Tutorial: Resolving Keychain Issues
If you can't access your keychain, or forget your password If you can't get into your keychain file because you've forgotten your password or the keychain file appears to be corrupt, there are a couple of options.
First, if you've forgotten your password, you can use the "Keychain First Aid" utility to make the keychain password the same as the login password. This can be accomplished via the following process:
1. Open Keychain Access (located in Applications/Utilities)
2. Go to the "Keychain Access" menu and select "Preferences"
3. Click the "First Aid" tab
4. Make sure the "Synchronize login keychain password" box is checked
5. Close the Preferences window
6. Go to the "Keychain Access" menu and select "Keychain First Aid"
7. Enter your username and password
8. Click the "Repair" button
The second option is to completely delete your keychain then recreate it. This routine is useful if your keychain appears to be corrupt or otherwise inaccessible. This can be accomplished as follows:
1. Launch Keychain Access (located in Applications/Utilities)
2. Click "Show Keychains" in the lower-left corner of the window.
3. Select the problematic keychain from the left-hand pane.
4. Navigate to the "File" menu and select "Delete Keychain '(name of keychain)'"
5. Check all options for deletion and press "OK"
6. Create a new keychain by going to the "File" menu, then "New" and selecting
"New Keychain"
7. You can now make this keychain your default if you desire by selecting it, then
going to the "File" menu and selecting "Make '(name of keychain)' Default"
Login as root and perform repair In some cases, problems with keychains can only be resolved when logged in as the root user.
First, you want to enable the root user:
1. OS X Mountain Lion: Enable and disable the root user
2. OS X Lion: Enable and disable the root user
3. Mac OS X 10.6: Enabling the root user
4. Enabling and using the "root" user in Mac OS X
After enabling the root user, and logging in under this account, again open Keychain Access. First attempt repairs using Keychain First Aid, and failing that, delete then recreate the keychain as described above while logged in as root.
Persistently asked for stored passwords If you are persistently asked for passwords in various applications that you have specified should be remembered in a keychain, your "login" keychain may not be active for one reason or another.
Navigate to ~/Library/Keychains/ (this is the Library folder inside your user's home folder). Find the file named "login.keychain" and double-click it.
Failing that, select the "login" keychain within the Keychain Access application and make sure it is the default keychain by going to the "File" menu and selecting "Make 'Login' Default"
Turn off Keychain synchronization in applications having problems If specific applications are experiencing issues when accessing password-protected material, the Keychain may be to blame.
The above comes from an article published on MacFixit.com.

Retina MBP 15 slow to connect to wifi after waking?

My new 2012 rMBP 15 is very slow to reconnect to wifi after waking from sleep. I've read the Apple support pages with no solutions found. It can take 10 to 45+ seconds for the wifi to lock on to my home wifi network after the computer wakes from sleep. While my Macbook Air (2010), iPad3 and iPhone 5 all reconnect almost instantly to the same wifi. Also I've noticed that after the wifi icon in the menu bar shows it's locked on there is an additional delay before actually being able to connect; like reloading tabs in safari or refreshing my Gmail inbox (in it's own tab not 'Mail app'). Any Ideas how to trouble shoot / fix this issue?
Really irritates me that this top of the line computer is slower than my other devices.....

Also SAME PROBLEM here, but also after booting, plus snail speed:

Green pixels on external monitor with MBA coming up from sleep?

Has anyone else experienced green pixels on external monitor with MBA coming up from sleep? I can get rid of these pixels either restarting MBA or switch off the monitor for a five secs and then switch it back on. These pixels do not show up within screenshots.. or neither on MBA own screen but they do reappear on external monitor (used with mini DP-DVI-adapter) after every sleep cycle.
http://ssh.nbl.fi/~nbl4264/gp/ (few pics where these green pixels appear on)

I have the same issue with my new macbook.
When i wake the computer from a partial sleep the screen flickers and i get line distortion through the image.
If i put the machine to sleep unplug the mini dvi adapter and replug it in and wake the computer up the problem disappears.
The issue is also intermittent doing about 3 times out of every 10 wake ups...
If anyone has any suggestions it would be great, I a using a new Dell 2208WFP monitor.

I upgraded to Mountain Lion.Now I have trouble waking it up from sleep mode. Why?

I upgraded to Mountain Lion on my MacBook. I am now having trouble waking it up from sleep mode. Does anyone know why or how to wake it up. I try tapping the space bar, trackpad & other keys. Sometimes I think it's never going to wake up.

I'm not certain but my new MBA 13...when in sleep mode comes back on from a black screen when I simply click on the left mouse button. Also, one time I did a SECURE EMPTY TRASH on files that totalled more than 1GB and it took so long that the fan kept increasing in speed so I pressed on the POWER button and the MBA shut...I was able to boot up with no problem.
