Stopping Laserjet Enterprise printers from sleeping

HI All,
To make sure that our printers are ready for use by staff during office hours, we have a script in place which telnets to the printer on port 9100 and issues an @PJL command. If we don't do this, we've found that when people attempt to log into the printer with their ID card (we use a secure, pull printing solution) their card is rejected on the first login but then works once the printer has woken up.
We've purchased some new M750 and M601 printers that don't seem to allow us to use this same approach. If I telnet to the printer and start typing @PJL the telnet connection gets immediately disconnected as soon as I type @.
Has anyone found a way of stopping these printers from going to sleep?
Thanks,
Phil.

Volume buttons stop working after wake from sleep

I have a Pavilion dm4-1162us. The volume buttons do not work after the notebook wakes from sleep. It works initially from a normal startup. A restart will also resolve the issue. The quicklaunch buttons are the default buttons, that is it is set so the "fn" button needs to be used to use the function "f1, f2, f3, etc." keys.

Welcome to Windows. Some devices do not like to be put to sleep in Windows.
There could be driver updates or hot fixes from MS to fix these.
A very proven method (though not for battery life) is to instruct the devices not to go to sleep when the system goes to sleep. You can do this via the device manager in the control panel.
Its not a gracious solution but it will do what you want it to do.

DNS server stops responding after waking from sleep

In order to save energy, I put my iMac server (10.10.3 + server 4.0) to sleep at night, when I won't be needing it to answer DNS queries. However, for a few days (and coincidentally after upgrading to 10.10.3) when the server wakes up at the preset time, the DNS queries all time out (from my other terminals, like iPhone). I have to SSH into the server, serveradmin stop dns and then serveradmin start dns.
Any idea?

In general, servers are intended to be always-on and always available, and servers are not generally configured to sleep.
If you'd like to log a bug report with Apple around to the failure to properly restart, use the Contact Us link at the bottom of the page here, or use the Provide Server Feedback from within the Server.app menus.
Pending resolution, If you need to have the server go offline for some reason, shut down and then reboot when necessary.

Stop mouse waking iMac from sleep

I have a new Logitech USB mouse I am using with my iMac. The problem now is whenever I put my iMac to sleep its woken up by the mouse.
Is there a way to stop the mouse being able to wake the iMac in Leopard?
Thanks.

In System Preferences, click on Mouse & Keyboard, then Bluetooth and uncheck the "allow bluetooth devices to wake this computer."

Macbook Air (mid-2011) Facetime HD Camera stops working after waking from sleep

Hi, for the past week or so (no more than a week), my computer has not been able to connect to my built-in camera. I have a mid-2011 Macbook Air (running version 10.7.5) and a Facetime HD Camera (version 6.46). I don't usually restart my computer unless I am having issues with it being slow or freezing and so usually just close the top of my laptop when I am sleeping or at work. When I wake my computer up and attempt to use Skype, Photobooth, or Facetime, I cannot connect to the camera. Restarting my computer fixes this issue but that's as far as I've gotten since I am not very tech savvy and do not want to do anything to jeopardize the data and documents stored on my Air (I'm in school so losing anything would be very stressful for me). I have gone into the System Information in my Utilities folder and my camera is listed under the USB tab but my computer refuses to connect unless I restart it.
Any suggestions or help would be greatly appreciated! Thanks in advance!

No Wi-Fi Connection after waking from sleep.

I keep having a problem of my MBP not reconnecting to Wi-Fi if my computer come out of sleep. The network connection shows up in my list, and when attempting to connect I recieve an error.
The only remedy is to reboot OS X, and then the computer automatically logins into the Wi-Fi connection.
Why is this?
It is very annoying if I leave my computer for a few minutes and return to continue using the internet and such, and I have to reboot my computer.
Thanks

If your using WPA try setting your WPA Timeout to 365 days. Seems to have stopped my disconnects waking from sleep.

HP LaserJet Enterprise 500 Color MFP M575 - Can't scan from Windows

We recently purchased and installed an HP LaserJet Enterprise 500 Color MFP M575 to be used as a networked all-in-one solution for a number of offices. I have been able to get it set up on our network and have installed the appropriate drivers on the requested Windows 7 x64 machines, and network printing works perfectly. However, it seems that despite the fancy scanning features available from the all-in-one itself (scan to email, scan to a network folder, etc.), I can't find any way to do an old-fashioned scan from Windows.
I have installed the full software solution available on the driver download page for the device, and while Windows lists the device as a "Multi Function Printer; Scanner" it does not recognize it as an actual scanner. The built-in Windows Fax and Scan simply reports that no scanners are installed. The software installation did not include the HP Solution Center (which I am used to seeing from my experience with various other HP all-in-one devices) or any equivalent for direct scanning. The driver download page for the device does not include any separate scanning drivers, so I can't be certain if they were included with the full installation or exist at all.Some of our staff also use Adobe Acrobat to scan, and even that fails to recognize the MFP as a scanner.
We'll eventually be setting up the device to scan directly to a network folder, but we need a fallback while IT takes their time getting it set up; I can't imagine that the simplest option is not available at all. I must be missing something here, any assistance would be greatly appreciated.
Edit: To add, I also ran the HP Print and Scan Doctor. Interestingly, it reports the device as a printer and only offers to "Fix Printing" without any sort of resolution for my scanning problem.

There is no change to this problem after 6 months since the last post. Put simply, and as stated in the previous posts, there is no way to scan a document and receive the image on your PC. If you are working with graphics for any length of time or want to create an image for inclusion as an image in a document or web page using this piece of equipment will not allow you to do so.
Great shame as every other function works well - it cannot be beyond the wit of HP to include a Windows application that enables you to scan an image, receive it in the software you are using at the time (e.g. Outlook, Word, Photoshop...) and use it in your work.
HP Printers several years older than this £1000+ Enterprise printer were able to do this simple job and have done so for a great many years. Just being able to use Microsoft's Fax and Scan would be start.

My Mail app opens unprompted everytime i reboot or awake my macbook pro from sleep. This was not an issue until i shut down my laptop for the first time in a while 2 days ago. ANy ideas how to stop this?

I recently shut down my MacBook Pro for the first time in a long time. SInce then, everytime i reboot or awake my laptop from sleep, the Mail app opens unprompted causing my computer to slow down incredibly, and some apps to freeze. I have no idea how to stop this or why it even started doing this. Any ideas on how to get it to stop? Thanks!

I have this problem too with my Macbook Air. Mail opens automatically every time my laptop sleeps. I actually just asked about this in my own thread. However, it is not causing my apps to freeze.

How do I stop aluminium wireless keyboard from waking computer from sleep?

Hi
My aluminium wireless keyboard wakes my computer from sleep, at random occasions. Sometimes after five minutes, other times up to four hours. Sometimes not at all. My iMac wakes up (annoyingly during the night, waking me up as well) and screen says "Connection Lost", showing the greyed out keyboard-logo. It's not lying either—keyboard doesn't work, for about 30 sec until the stupid thing finds it again and all is back to normal.
*What can I do to stop this irrational behavior?*
Could this be a bluetooth hardware-malfunction?
(Background: My iMac has been acting this way, as far as I can recall, throughout all of the 10.6.X-upgrades—from time to time. Reason I am posting this now is that I haven't had this problem for a couple of months now, but it came back out of nowhere the other night, about a week ago. And I haven't been doing anything out of the ordinary, that I haven't done at least a couple of times during this period where it all worked fine.)
Additional information: I don't know if this has anything to do with the problem at hand, but when using the bluetooth for something other than just keyboard+mouse, say syncing my Nokia phone, the mouse always goes haywire and acts all laggy, trickling across the screen as I try to move it.

Yes, that sounded indeed like a daft question, but as it seems changing the batteries did actually solve the puzzle. I am baffled by this, as the batteries claimed to be at 40% and shouldn't need to be changed. But I changed them after reading your reply, and the problem stopped. Now, one week and a couple of days later, the problem still has not reoccurred.
For one reason or another, once batteries drop under a certain level of power, the keyboard connection will start acting up. I feel a bit silly, should have checked that bit myself before posting my question, but I'm glad this solved my problem. Thank you ajduguid.

Update to 10.6.8 and HP F2100 and D2400 Printers stopped working. Restored 10.6.7 and printers from Install CD's but not working, Same with scanner

Help....
Updated to 10.6.8 and HP F2100 and D2400 Printers stopped working.
Restored 10.6.7 and printers from Install CD's but not working.
Same with F2100 scanner
Am I glad I kept Windows desktop as without it I would be scre**ed now
What is going on with this latest update as its like a return to Windows with things crashing or hanging up every few minutes????
On a MacBook Air that has not been updated everything still works so what has 10.6.8 done and why won't the restore to 10.6.7 work?
Steve

None of those things you mentioned were what I suggested.
I'm guessing the "ctrl click in printer preferences" means you Reset the Printing System?
If so, that is what I would have suggested if deleting it by selecting the ( - ) button and then adding it with the ( + ) button.
But, if HP has a fix, it likely needs to update its drivers.

New iBook Stopped Waking From Sleep

Hello,
I'm feeling a little sad because my two month old iBook has stopped waking from sleep as it usually does so quickly and above all else reliably.
The issue has occurred twice now, both today. The only thing I've done today which I haven't done before is run Onyx (daily weekly monthly).
The pulsing 'sleep light' comes on, but when I return to my iBook the light is no longer pulsing, the keyboard is hot and the iBook doesn't wake by lifting the lid, pressing power or space.
Anyone have any ideas? What are my options if not? Can anyone advise on returns times if I have to return to Apple?
Edit: Actually that's not true: I also added a user account today and turned on fast user switching. Shall I try a reset of the PMU? Will this have done any damage to my LCD, do you think? I think the keyboard was hotter than in normal sleep.
Thanks!

This should be an interesting thread, mine did the same thing today.
I put it to sleep this morning at around 42 pct battery and when I came home this evening it was dead. Battery power at 0 and would not start until plugged into the wall. Then I had to reset the date/time.
Called up Apple and they told me the PMU reset itself. That it should not do this but sometimes does, and if it does it again to call back. Seems to be charging up just fine, but my confidence in what's been a flawless machine is shaken.
Didn't notice if my keyboard was hot because I left the screen open. Anyone else?

Script lines to stop machine from sleeping while a script is running

I have a long script (in time that is) and sometimes the machine goes to sleep while it is running, thus halting the script. Is there a line I can add to a script that keeps the machine awake while the script runs?

so is there a way around is? how do I stop the computer going to sleep while the script runs? Or how do I protect password etc if using a script with a password in it?
There are a number of approaches. One is to encrypt/obfuscate the password within the script, decoding it on the fly.
Another is to store the password in the user's keychain and have the script retrieve it from there at runtime (this requires a lot more coding to capture the password on the first run, save it to the keychain and retrieve it later).
Another option may be to edit sudoers to allow the target command to be run without authentication, although this opens a whole slew of other potential issues, of course.
Of the three, for a program I don't expect to distribute, I'd probably go for the first option. Note that there are many ways of doing this, ranging from the trivial to the herculean - you'll need to decide how much is appropriate for your needs. One very simple approach (not recommended for high security needs) is just to put your password in a list - the data format of the list makes it more difficult than a string to extract from a read-only script, but it's only one line of AppleScript:
property pw: {"p", "a", "s", "s", "w", "o", "r", "d"}
set my_pw to pw as text
You could get a little more complex by reordering the characters:
property pw: {"d", "r", "o", "w", "s", "s", "a", "p"}
set my_pw to reverse of pw as text
Taking it on a step further, there are all kinds of encryption/transformation algorithms you can apply to further mask the data. Most common algorithms can be translated into AppleScript if needed.

Stop the iPhone from sleeping when in dock

Is there a way to stop the iPhone screen from going black when put in dock. I would like to use it as a clock while in the dock. I know that I can turn off the auto lock feature and get a clock app but i would rather leave the auto lock on if possible b/c some times i forget to lock it and put it down and it drains the battery. any ideas would be awesome.
Mark

If you leave the auto lock on, your iPhone will auto lock based on your chosen setting to auto lock automatically - hence the name for this setting, which is Auto Lock.
If you don't want your iPhone to auto lock, you must turn off auto lock. When auto lock is off, you can manually select the sleep/wake button to put the iPhone's screen to sleep.
Either that or get in the habit or re-enabling auto lock the first thing when removing your iPhone from the dock.

IMac - stop internal disk from sleeping

I have a 27" iMac Late 2013 running Yosemite. I am trying to stop the internal disk from spinning down or going to sleep. It is a Seagate 3TB ST3000DM001. If anyone any ideas on what I need to accomplish this please let me know.   I do not understand why they would set it up to spin down the disk. All it does is shorten it's life and replacing a drive in these systems is not that easy. The changes below are what I have done so far.   Thanks in advance!!

I reset my "disksleep" value to 0 but saw this message. I always thought this was just informative type message.
$ sudo pmset -a disksleep 0
Warning: Idle sleep timings for "UPS Power" may not behave as expected.
- Disk sleep should be non-zero whenever system sleep is non-zero.
$
I tried using the old "spindown" setting instead of "disksleep" but got the same message about "system sleep" is non-zero. Maybe it is telling me something.
$ sudo pmset -a spindown 0
Warning: Idle sleep timings for "UPS Power" may not behave as expected.
- Disk sleep should be non-zero whenever system sleep is non-zero.
Even though I could not find a “system sleep” or “sleep” setting in the pmset man page I thought I’d try both. The one that seemed to work was setting “sleep”.
$ sudo pmset -a sleep 0
$
I tried to see the value for sleep but it seemed not to exist. Which is strange because it accepted the command without an error.
$ sudo pmset -g sleep
Error: unhandled argument sleep
Usage: pmset <options>
See pmset(1) for details: 'man pmset'
$
What is interesting is that now when I run the command to set "spindown" or "disksleep" to 0 it does not complain that the "system sleep" is non-zero. Which I think is a good sign. Well I’ll know if it fixes it in a month.
$ sudo pmset -a spindown 0
$
$ sudo pmset -a disksleep 0
