After printing 'hpdot4d' process prevents computer from sleeping

Hi,
I noticed that after printing a document that the process named 'hpdot4d' continually writes something as seen in fs_usage preventing the computer from going to sleep. The computer sleeps fine before printing and won't sleep after printing. If I kill the process the computer will sleep again on it's own. I am using an HP Photosmart 8250 with the Mac Pro.
This is what shows up continuously in fs_usage after printing a document.
21:01:45.042 select S=0 0.100020 W hpdot4d
21:01:45.116 write F=2 B=0x65 0.000009 hpdot4d
21:01:45.116 write F=2 B=0x75 0.000002 hpdot4d
21:01:45.116 write F=2 B=0x65 0.000002 hpdot4d
21:01:45.116 write F=2 B=0x75 0.000002 hpdot4d
21:01:45.116 write F=2 B=0x65 0.000002 hpdot4d
Anyone else have this problem? Where can I make Apple aware of this if this is a bug that can be fixed? As far as I remember this wasn't a problem in Tiger.
Thanks.

For what it's worth, I've had that hpdot4d process showing up ever since I set up my HP officejet 5610 on my Mac, and I'm still running 10.4. I'm pretty sure this is an HP problem, not an Apple problem...

How to prevent computer from sleeping when downloading Lion from the recovery partition?

Hello,
I just got a new MacBook Pro that came with Lion. I'm reinstalling from the recovery partition and I'm on the downloading additional components stage. It has 3 hours to go and the computer keeps going to sleep. How can I prevent this? I don't want to have to babysit the computer for 3 more hours.
Thanks.

Looking for an answer to this question now. Did you find one? I'm about an hour into a 6+ hour reinstall of Mountain Lion from the Recovery partition on my MacBook Pro. So I can't change the sleep corners or caffenate it or do much of anything but wait. I want to go to bed and let it install overnight, but I assume it will go to sleep, and that will kill the download. It there any way to prevent it from sleeping now?
Even trying to think of something I can put on the trackpad to trick it into thinking I'm touching it.
Maybe ill put it under my dog, and her movements will keep it awake? Thinking outside the box here.
Any ideas would be appreciated.

Restore disk OS X Mountain Lion: Prevent computer from sleeping

Please help, I need to create a backup using the disk utility on my restore disk. However, the computer keeps going to sleep and corrupting the backup. How do I prevent my computer from sleeping while the imac is creating the backup?
Processor 3.06 GHz Intel Core 2 Duo
Memory 4 GB 800 MHz DDR2 SDRAM
I can not add anymore physical ram
Graphics NVIDIA GeForce 8800 GS 512 MB
Software OS X 10.8.3 (12D78)

I would recommend using a proper tool for backing up, if you want to create a bootable clone use either SuperDuper or Carbon Copy Cloner. Either that (or even better use a clone and) or use Time Machine.

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.

"Connecting to the network is taking longer than usual" message after I wake my computer from sleep

Connecting wirelessly after waking computer from sleep yields the message "connecting to the network is taking longer than usual". This only occurs after sleep, it also does not allow it to autoconnect like when starting the computer up. All
drivers seem to be up to date and happens at more than one wireless location, home and school. I have a windows 7 opperating system.

I just had the same problem with my HP Pavilion dv6 laptop.
I was able to resolve the problem by uninstalling my Intel Centrino Wireless Network adapter (but I did not delete the driver). I did this by right-clicking My Computer, Manage, Device Manager, expanded the Network Adapters group, and right-click the
Wireless Network Adapter and click Uninstall. I recommend that you reboot once this is done.
My laptop now connects to Wifi immediately after waking the laptop from sleep.
This is what finally resolved my problem. Sony Vaio with 64bit Windows 7. Wireless would sometimes take up to 3 minutes after Windows started to connect. After following these instructions, I first removed all wireless networks, then from the System Control
Panel I deleted (along with the driver) the Wireless Adapter. I then installed a fresh driver directly from the maker (not OEM).
I now connect to Wifi immediately after booting or waking from hibernation.
Thank you

How to stop my Time Machine external hard drive preventing iMac from sleeping?

I have a late 2012 iMac, and have discovered that sometimes (I haven't noticed a pattern of when it doesn/doesn't happen) the computer will immediately wake up after I set it to Sleep (Apple Menu>Sleep). Through elimination I have found that it is the the USB 3.0 external hard drive I use as a Time Machine back-up that is the culprit; unplugging it then allows the computer to sleep. If I unplug it, then plug it back in later on, this normally solves the problem for a while, but not forever. This same Hard Drive didn't cause the wake problem on my previous '08 iMac.
A big issue is that when the machine immediately wakes from sleep, the display stays off (until I move the mouse) - this is good from a power saving point of view, but means I don't know if/when the machine is immediately waking from sleep (I have to listen to the fan when setting it to Sleep mode to hear if it has actually woken back up).
I've searched the forums, but can't find another poster with the same problem as myself. Can anyone advise a course for me to pursue to prevent this from happening?
Thanks. Jamie

Hi Frank. Nope, I'm still having the same symptoms; the plugged in external drive (TIme Machine) will wake the machine up a couple of seconds after it winding down when put to into sleep mode. Ejecting the drive and then sleeping the machine works. After plugging it in again to do a Time machine backup, it will allow the computer to sleep soundly for the first few sessions (eg a few days of sleeping, waking, sleeping, waking, etc), but then it will then suddenly start preventing it from sleeping again after a while.
It seems I'm fortunate in my case that the display stays dark (or off?) when the machine has been woken from sleep, but this was actually preventing me from knowing the machine wasn't in fact asleep for quite some time; I only eventually cottoned on because there wasn't any delay when 'waking' my machine (which there normally is). I would then have to carefully listen to the spinning fans to know if in fact it had gone to sleep or not.
So, to summarise, unfortunately no, I haven't solved this yet. If anyone else has a solution, please let us know?
Also, I've noticed occasionally after waking that there is a relatively quiet 'crackle' sound (kind of electrical sounding) from the bottom-right area of the machine. This goes on every so often for about 30mins. I see this is also an issue with other people's late 2012 iMacs, but I've not seen if anyone has a solution to it?

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.

Prevent MBP13 from sleeping when closed power & ext display?

hi all,
i use my macbook with an external monitor and keyboard. i normally have my macbook charging and the lid closed.
i unplugged the mag charger and my external monitor went black. however when my lid is open and not charging everything works fine.
so my question is why does everything work fine when my mac is running on power and lid closed but does not when lid is closed and an running on battery. (however does when lid open running on batt)

Hi Radium88,
You can prevent your MacBook Pro from going to sleep using the steps in this article -
OS X Mountain Lion: Prevent your computer from sleeping
http://support.apple.com/kb/PH10679
Specifically -
Choose Apple menu > System Preferences, and then click Energy Saver.
Drag the slider that controls the computer’s sleep to “Never.”
Thanks for using Apple Support Communities.

Everytime I wake up my computer from Sleep Mode the sound starts to crackle on my X-Fi?

Sometimes I'll be playing a song and a few seconds in it starts to crackle and distort the music. I notice that it only happens after my computer wakes up from sleep mode. Usually restart can fix the problem.
I have an original X-

Okay, I seem to have solved the problem I posted about earlier. I noticed that the language preference in the upper right hand corner of the screen (between the date and time and the Spotlight icon) had somehow gotten switched from American English to French. When I switched it back to American English, my password worked when waking the computer from sleep mode. I have no idea why changing the language preference would affect the way the password works but that seems to have been the case. I'll post again if I experience more problems.

Mouse waking computer from sleep

I'm using a wireless USB Logitech mouse with my MacBook. Moving the mouse wakes the computer from sleep and I would like to disable this function. Is there a way to change the setting so the computer requires a keystroke to wake it?
Thanks.

I'd rather not buy a new mouse if I don't have to. I found this link http://www.macyourself.com/2008/08/28/prevent-accidental-wake-ups-when-an-apple- laptops-lid-is-opened/ that shows how to disable the lid wake function in terminal. Is there a mouse wake disable code in terminal?

Wake computer from sleep & sync iDisk?

I'm wanting to wake my computer from sleep & sync my iDisk at a set time in the day. Does anyone know if it would be possible, & if so how?
I thought if it could be done with AppleScript (wake & sync the iDisk) I could set iCal to run the script at a set time while sleeping which would wake the computer & run the script.

Your script will not run while the machine is idle, so you have to have some other process effect the wake up. This can be scheduled through System Preferences -> Energy Saver, or through the command line pmset, but you can't just have your AppleScript running in the background and expect the machine to wake on its own.
So you need to get a script to run your backup, and some other process (e.g. iCal) to start that script at the appropriate time.

I have a new I Mac running mountain lion. When waking the computer from sleep, all I get is a blue screen. I have to restart the computer.

I have a new I Mac running lion 10.7. When waking the computer from sleep, all I get is a blue screen. I have to restart the computer.

Did you not bring all your important data over from your old computer? Do you have a backup of the iTunes library that you can restore? If not, then its not to late, just more work that it should be.
You should be able to:
Backup the device to the new installation
Transfer your purchases into a newly authorized library
Recover any other media using third party tools as suggested in this post from forum regular Zevoneer
Restore the device from the backup
This process should switch the association of the device to the new library, preserving the data and settings in your apps.
May also be prudent to attempt a backup to iCloud directly from the device before you start... Settings > iCloud > Storage & Backup > iCloud Backup > On. It won't save any media but it would preserve the general account settings and documents in case anything goes wrong while you are trying to extract your other data.
When you get it all fixed, make a backup!

Change "require password to wake this computer from sleep or screensaver"

Does anyone know how to change the checkbox in sys prefs > security > require password to wake this computer from sleep or screensaver via cli?
I would like to always have this enabled, but individual users can shut this off...
Thanks

Code an AppleScript using the SystemsEvents>SecuritySuite>SecurityPreferencesObject>RequirePasswordtoWake then use the cli 'open' to run it?

Mail needs to be restarted every time I awake my computer from sleeping,

Every time I awake my computer from sleeping, Mail needs to be restarted.
Why's that?
The problem is that if I'm not aware of i it, my Mail stays offline.
Any help?
Thanks
Nico

This is a bug that doesn't affect everyone. I can't reproduce it and I don't know what triggers it. The following steps have been reported (but not confirmed by me) to work around it in some cases:
Turning off Dictation
Turning off the built-in firewall
Turning off the Energy Saver setting to allow hard drives to spin down when idle
Changing DNS servers
That's all I've been able to find out.

Woke computer from Sleep: USB doesn't work

So, I woke my computer from sleep, and now all my USB ports are dead.
I tried restarting, resetting the CMOS, removing the D-Bracket, which I had just installed (it didn't work either.). Any thoughts?
EDIT: All ports get power, none get signal.

Any further suggestions are appreciated.
Okay, with your front panel connectors, do they have a wire for pin 10 on the USB connector? That would be the one next to the blocked out keying pin (pin 9). If so, that could be causing your problem. If you remove the pin from the connector that could clear up the problem. I haven't personally had the issue, but I've seen it talked about. If your internal USB connectors only have 8 wires on them, then I don't know what to tell you...
