External UCube speakers don't work after awakening from sleep mode since 10.7.5 upgrade

Ever since I upgraded to 10.7.5 when I wake my computer from sleep mode...my external UCube speakers don't work unless I unplug them and plug them back in. I've already tried resetting the SMC. It recognizes and shows the speakers in the sound preferences...but no sound unless I reconnect the usb cable. Worked fine in 10.7.4
Any ideas? Its ridiculous all the audio problems being reported.

I have a mac mini (A1283) with OS 10.7.4. Upon upgrading to 10.7.5 it did not start up again. Instead, the light was on and the hard drive did not start up. The light on the connected USB mouse was not lit.
My solution:
Cold start with Command-v pressed.
This should start Verbose mode (see http://support.apple.com/kb/HT1492 ).
What happened on my mac mini was that the grey startup screen with the Apple logo appeared for a long while before the login screen came.
Maybe Cmd-v set open firmware params and fixed some corruption.
Anyway: my mac mini works again.

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

Keyboard volume keys don't work after waking from sleep

This problem has existed for many months on my 2009 Mac Pro. I'm running 10.6.3. The problem is reproducible 100% of the time. I use external speakers. Sound output is set to "Line Out."
1. Boot machine. External speakers work fine. Volume keys on keyboard (F11, F12) work correctly.
2. Put machine to sleep.
3. After waking from sleep, F11 and F12 no longer control the volume of the external speakers. The "pop" noise when hitting F11 and F12 is emitted from the internal speaker. The mute key (F10) does work for the external speakers, however.
4. The keyboard volume controls become responsive again by switching the sound output from Line Out to another output option and then back to Line Out.
This bug is a huge hassle. Does anyone have a solution?

I have several mid-2009 8-core Mac Pro's, all running Snow Leopard, and all have been having this problem as well.
I will not guarantee this is going to work for anyone else....but we have found a (slightly inelegant) workaround for it that has been working for several weeks now without fail.
Prior to putting your MacPro to sleep, run the volume all the way up and leave it there. Afterwards, put it to sleep as usual. We use the keyboard to do this, but I would imagine any method should have the same affect. However, I've not experimented.
Anyway...this has worked 100% of the time for us. The only downside of it is that you have to remember to run it up before....and then back down after waking (else that first alert sound or music file you play will really wake YOU up!)
If this works for anyone else, let me know.
Apple should never have let this one out the door with this bug. Especially, as Apple Support is....wanting, at best.

Ping and ssh don't work after waking from sleep

Hi!
I have been running Arch on my 2010 Macbook since May and there's always been this one annoyance which I can't figure out: after it is woken from sleep, the wireless (using netctl) happily reconnects and I can browse, check email, run pacman, do dns lookups---everything, it seems, apart from ssh or ping. Both ping and ssh seem to hang. If I reboot or restart [email protected], then they both work.
Running :
$ ssh XXX.XXX.XXX.XXX
connect(3, {sa_family=AF_INET, sin_port=htons(22), sin_addr=inet_addr("XXX.XXX.XXX.XXX")}, 16
where XXX.XXX.XXX.XXX is my work computer. (Full strace: http://pastie.org/private/xhmee0oltrnx3qmblnzq)
Running strace ping google.com (as root) gives the repeated lines:
$ strace ping google.com
sendmsg(3, {msg_name(16)={sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("173.194.34.102")}, msg_iov(1)=[{"\10\0\270\345b\325\0\2\336\36QR\0\0\0\0\353\376\2\0\0\0\0\0\20\21\22\23\24\25\26\27"..., 64}], msg_controllen=0, msg_flags=0}, 0) = 64
recvmsg(3, 0x7fff2f6d6f90, 0) = -1 EAGAIN (Resource temporarily unavailable)
(Full strace: http://pastie.org/private/bfygaqtccz0ms2w8hqea4g)
I can, however, sucessfully ping my router and other devices connected to it. I have not been able to find out anything relevant that might fix this. I've checked the MTU settings match those on the router and my other laptop running Arch does not have this problem.
Any suggestions on how to debug this further?
Thanks!

Screen is not working after resuming from sleep mode

Hello,
i got a problem with my ideapad u330 touch, after i got out of the sleep mode my screen will not come on, so I need to switch it off and back on again then it works fine.
I recently upgraded to win 8.1, i don't know if it has something to do with this, but before it works fine.
Thank you very much

hi McGuinness,
Are you able to recreate the issue if you boot in Safe Mode?
Things that you can try:
1. Press the Windows logo key‌ +R and type devmgmt.msc. On the Device Manager, navigate to the Display Adapter (right click > choose Properties) and on the Driver Tab, check if the Rollback Driver is clickable to restore the previous display driver.
2. Navigate to the Control Panel > Programs and uninstall the Intel display driver and reboot. Navigate to the D:\Drivers folder and locate the Intel Display driver installer (D:\Drivers\VGA\Intel) or download and run the file below to re-install the display driver.
Intel Video Driver for 64-bit Windows
Version 9.18.10.3165
After installing. Try to put the computer to sleep and observe (if the power button is blinking, this indicates that the unit is in sleep mode).
Regards

Can't get yosemite to working after waking from sleep mode

I just installed Yosemite to my Mac Mini. When the computer goers to sleep for more then 30 seconds I can wake the computer but then after i see the desktop I can't do anything on the computer every click i make does not respond and I have to force the computer to shut down and I have to reboot every time my computer goes to sleep.

I have the exact same issue for the first time after installing Yosemite. On resume from sleep, I can see the desktop, and can move the cursor with the mouse, but clicking on icons, etc. does nothing, and the keyboard does nothing. A cold boot works fine. This is a Mac Mini bought in the Summer of 2014. I run no unusual software. I have eliminated all log in items in Preferences/Accounts, reset the NPRAM, have no peripherals (other than standard Apple mini mouse and wireless keyboard), and have shutdown and unplugged to reset. It makes no difference whether a password is required or not - once it goes to sleep, this is the result, and only a forced shut-down by holding the power button and a cold boot give me control back. This problem does not appear if it merely goes into screensaver mode - which I invoke with a hot corner.

Wireless Mouse Doesn't Work After Waking From Sleep Mode

I have a MacBook Pro 13" 2.9 GHZ running on OSX 10.8 and when it wakes from sleep the wireless usb mouse no longer functions. I have to continually unplug then plug the mouse back in for it to work. Is there a way to solve this problem? I haven't found any definitive answers through searching the web. It's minor but irritating as I'm not fond of using the trackpad.

Would like to backtrack this discussion to

Firewire 800 drive dismounts itself after awakening from sleep mode

I have a 24" intel iMac ( running V10.4.10) with a FW800 Western Digital 500 GB attached - about half the time when it wakes up from a sleep the drive is removed from the desktop and I get the "improper removal" dialogue box. I called WD's help line and the best they could think of was send it back - other than what I've stated the drive works fine - ANYBODY got any ideas brighter than that??
PS: There 1st bright idea was to not plug it into a power strip but use the wall outlet - I did but was of no help.

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.

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

Network issues after returning from sleep mode

I'm noticing this issue on T440, Twists, T420s, whether it's Windows 8, Windows 8.1 or Windows 7. Sometime around the end of last year and the beginning of this year, my users suddenly started reporting problems with the machines after returning from sleep mode. The network adapter (whether plugged in or using wifi), would show limited connectivity and would not connect to the internet until the machine is rebooted.
I've tried updating drivers, using system restores, disabling the network adapters from shutting down to conserve power, OS network diagnosis & network adapter resets, none of which has worked. Hibernation is disabled on all machines.
The only fix I have is to reinstall the OS over the top of the system and reinstall all updates. Looking for help with this issue.
Thanks!
Solved!

Macmini 2011 on lion, goes to a blue screen om monitor when awakening from sleep mode, last 3 or 4 seconds, can anyone help? Thanks

Macmini 2011 on lion, goes to a blue screen on monitor when awakening from sleep mode, last 3 or 4 seconds, before desktop appears, can anyone help? Thanks

Depending on the system configuration, this may not
be unusual. The Mini that I use for my home theater,
which is connected to a receiver then to a TV, all via
HDMI usually takes a couple seconds to come up just
the way yours does. Same happens when I switch sources
on the receiver. Actually, it starts with the blue screen and
will sometimes flash before the desktop comes up.
It seems that when HDMI goes dormant, there is handshaking
that needs to be re-established, at least thats my SWAG on it.
On the other hand, the Mac Mini Server that I use as a work
station and is connected to a Thunderbolt Display, wakes to desktop
in a second, maybe two. On this combo, it just comes up to
the desk top.
It also probably depends on what processes were active when
the Mini was put to sleep. So it may take some time for it to get around
to reloading the desktop.

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..
