Energy saver does not put computer to sleep

i have a new 15 inch macbook pro running 10.6.4. When the energy saver (i have checked all the proper buttons putting computer to sleep after 5 minutes of non use) puts the computer to "sleep" it actually does not sleep...it appears to sleep but the sleep light says illuminated (instead of pulsing) and then eventually the computer battery is drained and the computer needs a hard restart. All other sleep methods properly put it to sleep from choosing from the apple menu to shutting the lid...I assume there might be some program that is running in the background but when i look at console activity i see nothing noted...any thoughts as to how to solve this problem? thanks

You might try a SMC reset:

Energy saver will not put Mac to sleep

I have a new Intel Mac mini. I am running off an external drive (MiniStack2). The drive was formatted and then had data transferred from old G4. The internal drive, when used as a start-up disk, functions fine. The external drive will not enter sleep mode (screen turns off, but not HD). The G4 had similar problem. Not sure why one drive as start-up drive and other does not. I have quit all active processes and tried every set of options - the machine will not put HD to sleep.
Is there a plist or other file I must reload? I am certain this is a software issue. Problem in 10.4.7 and 10.4.8 (and 10.4.x on G4)

Energy Saver doesn't put Powerbook into sleep mode

I've noticed many issues with Sleep mode on the PB line, but wondered if anyone else was having this problem:
PB will go to Sleep if it's told to (shut lid, Apple Menu -> Sleep, Logitech Keyboard Sleep/Shutdown button, etc), but it will not put itself to sleep if left idle for ANY amount of time. Does not seem to matter whether or not it's plugged in.
I should not that the screen goes blank, but the hard drive never seems to spin down, little white light on lid release never comes on, etc. So it could be Sleep VS Deep Sleep, don't know really.
Note, this is not unique to my machine; others in the office where I manage systems/network have this problem, and we run a variety of G4 powerbooks 15 " models.
Not really sure when it stopped sleeping (have been on the ball with 10.4.x updates) but has been the case for some time now.
Also, have reset the PMU, and has not made any difference. Any one else having similar issues? Seems to me like Power Management of the G4 may have broken along the way.
Cheers,
J
Powerbook G4 15" Mac OS X (10.4.8) 1.5 GHz

Joe,
No Classic running; haven't had Classic on my system for at least 6 years. You could say that I'm a bit of an OS X biggot, to be honest. No looking back, and all that.
Used Top/Activity Monitor, and nothing running save the daemons/procs that usually appear - certainly nothing that jumps out at me as a problem. Even disabled all virus checking just to make sure it hadn't developed an incompatability with something in one of the last updates - no effect. Seriously, this is a case of 'it worked yesterday, and now (post updates) it doesn't.' Not that it's evident what the culprit is; nothing on the 10.4.8 updates seems a likely candidate, nor does anything on the 10.4.7. And not that I could even pin point when it happened either - simply became evident over time that hard drive wasn't spinning down, Sleep light wasn't coming on, etc.
I'm tempted to fish out my ol' TI Book 400, and give it a go and see if it has problems. Would at least eliminate any hardware dependencies that might be an issue. Don't know that I can be bothered though - in the grand scheme of things, it's just a minor thing and digging much deeper would require effort that would get in the way of real work.
In any case, all suggestions are welcome and help is appreciated.

Computer does not put itself to sleep when used in lid-closed mode

Hi. I'm having a small problem when using my macbook pro with the LED display, lid closed and with external keyboard and mouse. If I leave the computer unattended, the display goes to sleep at the time specified in system settings under energy saver. The computer, however, does not go to sleep - the white power indicator remains solid and noises for new email etc can still be heard.
I should probably just try to remember to put it to sleep manually but I keep forgetting. Does anybody know what settings I need to adjust?

I tried cycling the old battery many times, and the computer would still shut down unexpectedly instead of going to sleep when it ran out of power. I got a free replacement from the supplier [http://myworld.ebay.com/cbkusaelectronics>, but I have cycled this new battery twice now, and it still does not go to sleep when it runs out of power. The capacity of the battery is fine (4.9 Ah), and the timing calibration seems fine as well. I have two older batteries from NewerTech and they allow sleep every time, so I think my computer is fine. Can anyone enlighten me about the cause of this problem? Does my battery lack some 'sleep battery' cell in it for use after the other 4 cells discharge? Or does my battery lack a chip that communicates with the computer? Is there any hope of getting this battery to support sleep when discharged?
Has anyone else seen this problem consistently in a brand of battery? Does anyone have a recommendation for a cheaper battery that does not exhibit this problem? I have been happy with NewerTech, but they cost over $130.
(I only paid $44 plus $10 shipping, so I probably got what I paid for. It is maybe still worth it to have a high capacity battery for such a low cost, but I can't rely upon it in those last few minutes or I may lose work.)

Closing top does not put MBP in sleep

Hi there,
My MBP does not auto-sleep when I close the top. any clues how to fix it?
Cheers.

It has been suggested elsewhere that you have to be careful not to bump the MPB until the sleep light comes on (pulses), because the sudden motion detector can prevent sleep from fully engaging. Safe sleep can take about 5 seconds to completely transact.
Has also been reported that unplugging usb peripherals will interrupt the process of sleep engaging.

Energy Saver panel not working-Mac drive keeps powering up

I have a 17 inch "Lampshade" iMac running 10.2.8. I have set the preferences in the Energy Saver panel to put the computer to sleep after about 15 minutes and to put the hard drive to sleep when possible. But it never happens. I'm sitting in the room with the computer now and about every 5 minutes I can hear the hard drive spin up for about 30 seconds, then it stops. When the drive is not spinning, I can still hear the computer is on. What exactly is sleep mode, for both the computer and the drive, and should the hard drive periodically start up when it should be sleeping? If not, how do I get my machine to really sleep? Thanks for the help.

Hi! HERE is some info on sleep. Putting the hard drive to sleep is really something I avoid. It will last just as long by never letting it spin down and the computer will come back to life faster. i would let the display sleep but only after 30 minutes or so or even 15 if I consistently left for long periods. The life of a hard drive now days is usually given in start/stop cycles which is more hard on one than running it 24/7/365. I run all my stuff 24/7/365 except for the monitors which I let sleep after 30 minutes idle. Tom

Screen Saver does not use selected Screen Saver when activated

Screen Saver does not use selected Screen Saver when activated. After "Start screen saver" elapse time has been reached, a blank black full screen is displayed. I can activate the selected screen saver by using the hot corners function. Any help with this matter will be greatfully received.

Hi again sassey,
You're assuming correctly. Simply change the settings so that your screen saver activates before the sleep settings.
Hope this solves your problem...

Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.

My new mac mini with Maverick does not go to deep sleep even if i press power button or Apple-Sleep mode.

Hi.
I have my new mac mini with Maverick that does not go to deep sleep even if i press power button or menu Apple-Sleep mode. He goes only to something like stand-by (power lid is on; after i turn off and then turn on the power he does not wake up just starting). I tried "sudo pmset -a hibernatemode X", tried mode 0,1,3, and even 25. nothing helps. he goes to deep sleep (when all data on HDD) only first time after i change hibernatemode couple times and force it to sleep. Today i even tried to force it to sleep (menu Apple-Sleep mode) and NOT turn off the power for whole night, in the morning he is in this "stand-by" mode anyway.
Could anyone help me please? i need it sleep but don't want to keep my power on for whole night.

Thank you.

I found the answer just after posted this. Thanks to a user named CloudWalker. Solution is to go in AppStore, View Account under "Store" Menu and unhide any purchases.

My MBA does not start up from sleep

My MBA 13" mid 2013 (Mavericks) does not start up from sleep at times, or at least is very slow (1-2minutes)
As far as i remeber the only thing installed fairly resent is Virual Box.
It does connect to my iPhone when its connected to via USB but the sceen stays black.
Anybody else with this problem?

Hi bryan808-
It could be that the failure and installation of the update are simply a coincidence.
Back up. Then try removing all PCI cards and disconnect all external devices except your monitor, keyboard, and mouse. If that configuration will wake from sleep then start adding devices and/or cards one at a time until you find the culprit that keeps your machine from waking.
If you are really running a G4 you will have better luck posting in the appropriate section of that forum: Ctegory: Power Mac G4

Technically, to make the function keys work you don't need to change the second box to dash. I don't know why I gave that advice, but it isn't necessary. I guess I said that simply because that's what I have it set to.
The reason there are two boxes is so that you can set Exposé to using both the function keys and the mouse. For example, if I have +All Windows+ set to F9 and Secondary Mouse Button, then it will show all open windows if I click F9 or right-click. That is why you actually don't need to have the second boxes for any of these set to dashes. You could set them to your mouse buttons, or if you wanted you could set the first box of any of these to any function key, as long as it isn't set to the same one as the key you want to use for your shortcuts within FCE.
I hope this made sense, I realize that I might not have explained it very clearly.

I am trying to export a Numbers spreadsheet to a csv file, but it does not put the commas in

I am trying to export a Numbers spreadsheet to a csv file, but it does not put the commas in. I want to use it with an HTML table generator tool, but the tool is looking for commas. The Export to CSV exports it as a spreadsheet with all the formatting removed, and no commas.
Here is the html table tool:
http://www.textfixer.com/html/csv-convert-table.php

Numbers '09 create CSV files with comma separated values if and only if your system is using decimal period.
If the system is using decimal comma, the CSV files are created using semi-colon as separator.
