2nd Monitor Not Detected After Sleep Mode

This setup was working perfectly fine on Windows 8 Pro before the upgrade. I upgraded to Windows 8.1 Pro and now when the laptop goes into sleep mode my secondary monitor will not turn on after I wake the system up.
The only way to get it to work again is to reboot or unplug and replug the monitor back in.
Windows reports all drivers are up to date.

Hi,
This issue can be caused by driver or your power plan.
Please update the display card driver from Manufacturer website.
If the issue still persists, please change Graphic settings as Maximum performance in power options to check the results.
If we still fail to get this fixed, please find the event log of hardware and upload here for further research.
Keep post.

HP Officejet Pro 8500 Wireless (Vista x64) Will not print after Sleep Mode

Hello,
As the title says the printer does not print after coming back from sleep mode. Before entering sleep mode the printer works fine and is responsive. After coming back from sleep mode the printer is still responsive (buttons on the touch screen can be pressed) but unfortunately does not accept any print jobs. Currently, I restart the printer to get it to print. It is connected wirelessly through WRT610N Linksys Router. Any suggestions or solutions would be greatly appreciated.

I have been having the same problem all during my warranty period. But no one ever told me it was a firmware problem until two days ago connected to the sleep mode for the wireless one. Supposedly, they have downloads for wire ones now online which I found for 909a and 909b, but not 909g which is wireless. Now I am out of warranty and they won't replace it. I have a long history with tech support since early 2010. Right now, they are sending me a power adapter to try, said to turn off sleep mode (which I dont' know how). Then I told them I found online a firmware download, Apr 2010 to update firmware. My current version is different that the one listed for the download. So, I'm going back to TS to have them fool with it. Has anything worked for you?

2nd Monitor not detected on ATI HD 2700

Here is the short version of my story. The company bought a new Intel PowerMac Quad G5 2.5 base model, NO upgrades to replace a PowerPC G5 Dual 2.3. This was due to the fact that After Effect CS4 will only run on an Intel Mac. Not a big deal until the fact that our current Xsan is running 1.42 and that will not run on 10.5. So, I downgraded the OS to 10.4.11 on the Intel Mac, set up the network and fiber channel connections and everything looks to be running fine but only one monitor will come on. The Intel Mac came with a ATI Radeon HD 2700 with dual DVI. We have a 23" Apple Cinema & a 20" Apple LDC (with a Apple ADC > DVI converter) screens. Both are working but only one will be detected on boot up. Here is what I've done so far:
1: Switched the connections, but still only one will show up.
2: Only connected one monitor but tried port 1 and 2, both ports are in working order.
3: Moved the ATI card to the second x16 PCIe slot, same result
4: Replaced the ATI card with a Nvida GeForce 6600 PCIe (was in the PowerPC Mac), neither monitor would come on.
5: Placed both the ATI and Nvida cards in the computer (could hear them yelling at each other), only the the ATI would have a monitor come on.
6: Downloaded the 10.4.11 combo update and re-installed it, same result: one screen.
7: tried to put the kitchen sink in computer but could make it fit.
8: Triple checked my connections and power, all are fine.
So, any help would be great. I just don't know why this card will not detect the second monitor. I've looked in the System Preferences and checked the profile, the card is there and looks fine.
Thanks for your time.

The 2600 is not supported on Tiger. There is a hack to get some type of drivers, but still not right.
What you needed was a 2007 Mac Pro 8-core 3GHz if possible, Apple Store Special had them from time to time.
http://store.apple.com/us/browse/home/specialdeals/mac/mac_pro
This hits on one area where it is easy to hit wall and hard place, there is no real backward compatibility. New hardware equals OS it shipped with. The Nvidia 8800GT needs 10.5.5+ (10.5.2 minimum but terrible driver issues) and same for Radeon 3870 (the OEM card is your best bet but limited to 10.5.2).
Which is why people hang onto and you continue to see strong prices for Quad G5s probably.
Adobe stuck to Carbon too long. And now they have to catch up to where Snow 10.6 will land.
You still want to use the "Intel G5" it seems in your layout. Maybe Apple should have called it "G6" and painted the box black!
2008 Mac Pros only run Leopard properly, even though Leopard was so new it wasn't really ready and vendors like Adobe didn't have time yet (and some had to wait for bugs and 10.5.2 to even begin to port to Leopard, besides the ".0" version changed - a lot - from what they had last seen.
You really are between rock and hard place. People really hate and detest the old Radeon X1900 for its design, heat, noise, and how it clogs with dust regularly, but at "only" $399, and already 2-3 yrs old, worth a look.

Having issues with iMac not working after sleep mode

When waking up from sleep mode or turning machine on in the mornig computer will not recognize the mouse or track pad. I have a 3.06 GHZ Intel Core 2 Duo.

sudo nvram boot-args=”-p -r” should get the computer to reset the nvram. After words its a good idea, to go back into Apple Menu, System Preferneces, Startup Disk, and make sure your Hard Drive is selected.
Is the OS up to date? if not, why not try running software update?
have you tried repalcing the batteries?
Have you tested with a wired keyboard or mouse? (dose it have the same issue)
Have you tried a safeboot?

Touchsmart 520-1047c Mouse and Keyboard will not work after sleep mode

I have an issue which I need some help with. When my computer goes to sleep the wireless mouse and keyboard will not work unless I restart, however each one will wake the system up but will not operate after that. I have tried just making the display go to sleep, both go to sleep but that makes no difference same issue occurs. The only work around I have found is going into the power settings and turning the sleep mode off for booth the computer and display. This does not solve the problem it just masks it. New batteries, unplugged and replugged the dongle, updated the bios and all drivers. Don't know what else to try. Anybody know how to fix this? Thank you in advance for your help.

Safari will not work after sleep mode

After going into sleep mode safari will not work. Firefox works fine, mail is fine. Happened after upgrade to O S x . Browser is Safari 8. How do I fix this?

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

Screen not refreshing after sleep mode

Hello All,
I have had a problem since 10.7.XX where my screen does not refresh after the computer goes into screen saver mode and then into sleep mode. When I move my mouse to resume i get a line drawn where I move my mouse and it reveals the login screen slowly. I can click on a login account and a small section of the screen refreshes where the login password is. Once I login it goes away. Was hoping Mountail Lion would address, but the problem continues from Snow Leopard. I am on a Imac 24" 2009 3.06Ghz dual core with 4 Gig of Ram, Nvidia GeForce 8800 GS 512mb. Thanks in advance for any advice.

Hello,
See if it's related to this...
It also seems to be related to later OSX versions, like 10.8.x & 10.9.x
The 2012 macs (and later apparently) (also later OSX versions on earlier Macs can do it also), not waking normally from sleep after hours being in sleep. (noted here ...

Bluetooth magicMouse & keyboard not responding after sleep mode

Hello,
I recently upgraded from Lion to Mavericks (10.9.1).
A very annoying bug happens every time the macbook pro exists from sleep mode.
In this situation, when the mac wakes up, Bluetooth devices (magic mouse & wireless keyboard) do not respond. Since I am using the mac in clamshell mode with external monitor, this is very annoying because I have to open the laptop, and turn on/off Bluetooth manually.
Sometimes the same problem arises for the internet wifi connection, which do not reconnect.
I am very surprised of this bug.
Does anyone have the same issue?
I was thinking to do a clean installation, as suggested in some posts, but I don’t believe this will solve the issue.
This issue HAS NEVER APPENED in Lion.
Thanks for support.
Alberto

** SOLVED ***
If you have a early 2011 MBP, the optibay SATA is a 6GB bit is really support 3GB/s only.
If you have a 6GB SSD, install it in the ORIGINAL adapter and the original SSD in the optibay.
This will **SOLVE** the issue.

TS3048 wireless keyboard not responding after sleep mode

My Apple Wireless keyboard (old style with numeric keypad) does not respond properly when my computer exits sleep mode. Keys either don't work or a single key hit produces multiple letters / numbers on the login box. The only way to get the keyboard to work properly is to turn it off, wait until the computer says it's lost the keyboard connectilon, then turn the keyboard back on again.
I tried a newer Apple Wireless Keyboard (current model) with this computer, and it works properly.
Anyone have an idea as to what's going on here?
Thanks

Mavericks Second monitor not detected after wakeup from sleep

Hi everybody,
seems like my problem is getting worse after updating to the latest Mavericks (10.9.5), but the general problem came up with upgrading to Mavericks.
I have two monitors connectet to my 3,1 MacPro with ATI Radeon HD 2600 XT 256 MB, which worked without any problems for years (since SnowLeopard).
After upgrading to Mavericks the Mac started loosing the connection to the second monitor after waking up from sleep.
At first only sporadically and then coming up more often. Some Google search showed that I wasn't alone with this problem. When I first started to find a solution for this, some of the workarounds others recommended seemed to help like resetting the PRAM, choosing another resolution with pressed alt button etc. but over time nothing really solved the problem. I only had a chance to get back my second monitor whenever the problem ocurred. Today none of these procedures seem to help, so I give it a shot with this post...maybe someone has a real solution for this (or at least can confirm exactly the same problem so that I can rule out some other reason than a buggy Mavericks?!?).
What I can rule out from trying different setups:
- It is not a problem of monitor brand (no NEC, both same model Xerox brand) nor size (both same resolution and 22")
- it is not a problem of connections and cables (switching the pluging switches the problem to the other monitor)
-> which brings me to the idea that the problem occurs with just one of the graphic cards ports. But since I have no other card available I'd like to rule out software problems before buying new hardware!
- The problem comes up only when waking up from sleep (immediately trying to reboot after the problem has ocurred brings no solution, the secon monitor stays undetected). Shutting down the Mac and booting up after a while (no specific time, but at least a couple of minutes) brings up both monitors perfectly.
- The monitrs try to get through to the Mac: when switching off the undetected monitor manually and switching it on again, it displays: No signal, going to sleep
Hope there is some help around here...this is really getting annoying!
Yours,
Ray

The weird thing is that every morning, when I move my mouse to wake the computer, both displays go from black to show the desktop but the second display immediately goes back to black. Unplugging it and plugging it back in eventually works after multiple trys. Restarting the computer sometimes works but not always.
The only other major change to my computer before this started happening is that I installed Leopard.
So far I've tried setting my Macbook Pro not to go to sleep but that didn't change anything.
Should I try setting my displays not to go to sleep either? I haven't tried that because Energy Saver warned me that it could reduce the lifespan of the display.

Ethernet Not Connected After Sleep Mode

When my computer goes to sleep and I wake it up again the ethernet port shows up as not connected in System Preferences / Network. I have tried unplugging it and replugging ir back in, disabeling other network adapters like wifi, resetting pram and can't think of any others to try.
The issue has been going on for almost 2 years. On my MacBook Pro I have had this issue for a while. Both in 10.7 and 10.8 versions of the OS.
The only thing that works is to reboot the computer and we are good again.
Any ideas on what to try next or what tis going on?

Monitor won't wake up after sleep mode

Does anyone know how to fix the monitor, so it starts up after sleep mode? When my computer comes out of sleep mode the monitor doesn't always come on. Does anyone else have this problem and do you know the cause? The computer is only a few months old and hadn't had any problems.
Thanks,
Shaneil

Well my solution may not be the most cientific one but it works for me (at least until the real solution comes to the public)...
My computer has the problem that when it goes to sleep mode she never comes back... but it the screen that does not comes back... all the system is workin in behind (its like the brightness level was set on the less power possible) so i had to turn off the computer and had to do for a long time some times i had to wait that the computer cooled off a little and then try again to turn it on... I some tried things that the support page of apple said it could be... but did worked out... i dont know i think is a problem over 2 factors...
1. heating (the screen generates to many heat but, TO MANY!)
2. tiger os the OS "sleep mode" (it knows that the screen its heating a lot and tries to go to sleep to prevent over heating and damage)
So based on this i tried conecting a external monitor to the computer while she was unable to "awake" (or to show some thing in the screen)... and it worked whit no problem at all... so my conclusion was to prevent the over heating (1st factor) and the sleep mode (2nd factor)... so I deactivated the sleep mode setting up the computer to a never sleep mode... and to prevente the over heating well I use a low bright and when i need more brightness (to se the colors of what im doing or some thing like that) I use high brightness... when I away I set the brightness level to no brightness so there is no over heat and no sleep mode (cus if it is deactivated and it over heats it will go to sleep anyway...
Soooooo....
1. deactivate Sleep mode...
2. Activate a Screen saver...
3. And remember to contro your brightness your self... and turn it off when you are not using your computer...
well i hope it works for some body :P cya...

Upgraded to lion now my wi-fi loses connection after sleep mode, it still shows as connected but does not go out to the internet. Please help

After I upgraded to lion I have been having constant issue with my wi-fi after sleep mode. I close the lid and when I reopen I open safari and cannot connect to the internet. Wi-fi is on and I am connected to my router, but it doesnt seem to be on the internet. Now how I resolve this issue is turn of the wi-fi and turning it back on, then i am back on the net. this is mos-def a bug i have never had that problem with snow leopard. Please assist or provide hot-fix

I have the same issue and have to cycle the wireless modem on the laptop. Doesn't matter if I'm on a preferred netowrk or no, or if I stay on the same network or move. I come out of sleep, I have to cycle the modem.
It's not life threatening, or anything, but it's a hassle. I didn't have the issue with Snow Leopard.
