Sleep-wake

Thu, 23 Oct 2008 06:39:45 -0500

My iMac (C2D latest OS etc) seems to wake at random and then fail to
sleep after the period set in Preferences. The wake event is recorded as:

Oct 22 21:06:42 upstairs-2 configd[14]: AppleTalk shutdown
Oct 22 21:06:43 upstairs-2 kernel[0]: System Sleep
Oct 22 21:06:42 upstairs-2 configd[14]: AppleTalk shutdown complete
Oct 23 04:40:01 upstairs-2 kernel[0]: System Wake
Oct 23 04:39:53 upstairs-2 airportd[3855]: FastFinder scanning channels
again

The computer will stay switched on with this system.log message every
two minutes or so:

Oct 23 10:00:33 upstairs-2 ntpd[27]: sendto(17.72.255.12) (fd=23): No
route to host

Any idea why it might wake/fail to sleep?

Thanks, Rob

Scheduled Shutdown and External Hard Drives

Sun, 05 Oct 2008 06:52:19 -0500

I have my iMac scheduled (via Energy Saver prefs) to shut down at 3 AM and
start up at 8 AM. I'm not sure if I should adhere to such a routine, or
simply leave the machine running 24 X 7 (both alternatives have their vocal
supporters, and I'd welcome your opinions. :) ).

I also have Time Machine backing up to an external drive, and will be
running SuperDuper! to a second, daisy-chained external.

Prior to getting this machine, I'd only connect an external drive when I
wanted to perform a manual backup; I'd then dismount it and turn it off,
_especially_ prior to shutting down the computer to which it was connected.
As I understood it, that was the recommended way of connecting/disconnecting
an external drive.

But now that the externals are always connected and "on" to enable automatic
backups, I'm unsure what happens when the Energy Saver schedule kicks in to
shut down the iMac: Does it shut down the system "gracefully," by first
dismounting the external drives?

Not sleeping

Tue, 30 Sep 2008 19:58:24 -0500

My iMac (late 2007) running 10.5.5 (and previously 10.5.4) seems not to
sleep unless I make it do so manually.

The Energy Saver setting doesn't seem to work, but on the other hand
display sleep does work. This suggests that something unexpected is
accessing the hard drive.

Is there a known bug regarding this? If not, is there anything I should
do to find out what is stopping sleep.

iMac C2Ds won't power up

Wed, 03 Sep 2008 11:51:35 -0500

I recently purchased 29 new iMac C2Ds and then went to Europe for 24
days. When I recently returned, I found two iMacs which won't start
up upon pressing the power button. Having seen similar behavior on an
iBook, I'm wondering if there is a trick to get the circuit's 5V of
standby voltage to actually do something.

G5 iMac Sleep Setting Won't Work

Wed, 03 Sep 2008 07:25:16 -0500

I can manually make it sleep by hitting command-option eject, or by
using the Apple menu sleep command. It is set for sleep after 10
minutes in the Energy pref. pane, but it won't sleep. When I
troubleshoot this issue, I am making sure there are no apps running that
require a confirm command to shut down. Also making sure no wonky games
are running that interfere.

This machine is the last G5 iMac...it has the Eyesight camera, 1 gig of
RAM, and the latest version of Leopard. The Apple forums talk about a
sleep issue with some G5 iMacs, but they appear to be earlier models.

Any suggestions? Thanks, as always.

Strange power problem

Tue, 02 Sep 2008 22:08:08 -0500

Since the last security update I installed, my iMac's power settings (for
turning the screen off) have been reversed.

They're still set correctly in System Preferences: turn screen off after 3
minutes. However, since the update, the screen now turns *on* after 3 minutes.

Normally, I switch the screen off by moving the mouse to the corner of the
screen, but I'm now finding the screen comes on *exactly* 3 minutes after
doing this! I've tried rebooting, and changing the settings before changing
them back, but it still does the same thing.

Drive spins up every 15 minutes

Sun, 13 Apr 2008 14:56:22 -0500

I'm running 10.5.2 on a Core 2 Duo iMac.

Every 15 minutes I hear my Firewire drive spin up for some reason. It's
not on even 15-minute boundaries, so I assume it's tied to my boot or
login times.

It's not Time Machine, it only runs hourly.

I never noticed this happening with the iBook G4 running 10.4.11 that
this machine replaced.

Some third-party utilities I'm running that might be suspects are
SMARTReporter and Compost. But I was running them on the iBook, too.

I tried running fs_usage, to see if I could catch any unusual process
running when I hear it spin up, but nothing really stood out. I saw
Compost, but not at the times of the spin-ups.

I tried using the Energy Saver option not to spin down drives. This is
a little less annoying, since there's no spin-up whine, but I still hear
the sudden buzzing of the drive as it's being accessed.

G5 iMac likes to sleep

Tue, 08 Apr 2008 04:11:42 -0500

Dear All

This one just in.....

"We have a problem with a G5 iMac, the mac keeps turning itself off (as if
there was a power cut), we have checked connections and changed the power
cable but it still keeps doing it every now and then."

On-board power supply transformers failing?

Or tsetse fly infestation locally?

Your thoughts?

Airport not working after sleep?

Mon, 07 Apr 2008 23:17:06 -0500

Intel iMac, OS 10.4.11.

After waking the thing up from sleep, Airport seems to be taking a long
time to re-acquire the signal from the wireless point that I've got
plugged into the DG814 modem/router.

(Still running a non-wireless enabled old G4 on the system, so just
plugged a wireless point into the router a couple of years ago).

Other wireless Macs on the system don't have the problem, so it's an
iMac issue, not a modem/router or wirelss point issue.

Tried restarting, turning the router off and on and ditto the wireless
point, but no real joy. It always comes up in the end; just takes time.

I suppose I could just plug an ethernat cable in, but does anyone have
any ideas what might be the problem?

It should sleep on schedule. However, when I had a similar problem it
was due to an application not allowing it to sleep. Try a scheduled
sleep while you're around - with your normal app set up running and see
if it obeys. I forget now exactly what it was that prevented the sleep
but I know it does work as it did it to me yesterday - went to sleep at
the scheduled time which I'd forgotten to wipe - and slept half way
through encoding a dvd... It started encoding again when I woke it and
seems to have picked up again where it left off but I haven't played the
finished product yet...

What might causing this iMac heat-when-off problem?

Tue, 05 Feb 2008 06:51:33 -0500

Normally, we leave our computers on and sleep them. I borrowed my
daughter's keyboard yesterday so I turned off her iMac (the now
discontinued 17" model) we bought last June. Today, when I reconnected
the keyboard and attempted to turn on her iMac, nothing happened when I
pressed the power button on the back. I tried several times and nothing
happened. At first I thought it was dead.

Then I noticed that the back was hot--- the quadrant right above the
power button. I unplugged the unit. It cooled off and I was able to
start it again. It took maybe three times as long to start up as it
used to. After running it for ten minutes, I shut it down again and,
upon returning one hour later, it was hot again! After unplugging it
from the wall socket, it has again cooled. I'd appreciate any ideas
about what might be going on and how to take up this problem with Apple
Care. Thanks.

Mains leads

Fri, 30 Nov 2007 13:53:54 -0500

Hi Some,

Did any of the iMac models come with strain relief facilities on the
mains leads do you know, the sort of thing that would stop the mains
lead pulling / falling out when you turned the screen (unit) a few
degrees to stop reflections or share the screen with a fellow student
etc?

I have had that happen on stand alone CRT's but then so doing doesn't
lose all your open data and most of the stand alone TFT's I've used do
have cable guides built into the stand so they don't generally suffer
the same issue.

All the best ..

iMac G5 fan won't stop blowing

Tue, 10 Jul 2007 14:13:58 -0500

Hi,

Usually, I only hear this fan blowing when I have a CD or DVD in the
optical drive. Now, however, I have removed the DVD and the fan
continues blowing even after a reboot. Is there anything I can do to
stop this or does the iMac need to be taken in for AppleCare hardware
support?

Thanks.

intel Imac - wont go to sleep (another)

Mon, 02 Jul 2007 05:48:59 -0500

hey folks,

i have an intel based 20" imac sitting on my desk, w/ a second monitor
connected & running xp in parallels. even tho i have it enabled, my
mac will not go to sleep mode by itself; it will go to sleep if i use
the apple menu. it will shut the displays off w/o problems.

i thought id see if there were any discoveries or consensus on this
subject, which seems to be popping up occasionally.

as far as usb devices, i have:

- the standard keyboard
- ms optical mouse plugged into keyboard
- Western Digital MyBook USB 2 external harddrive

..there is no movement of the mouse preventing sleep. the WD claims it
will go to sleep when a computer tells it to (confirmed w/ manually-
induced sleep).

im going to try some things when i get home, like unplugging the
mouse, and shutting down parallels (cant remember if ive tested for
that), and will report back.

thanks,
sm

SeaMonkey and sleep mode, with OSX

Thu, 28 Jun 2007 22:15:19 -0500

preface: I use SeaMonkey (SM), the continuation of the abandoned
Mozilla Suite.

post:
Any Mac OSX SM users have problems with their machine staying asleep?

I rarely ever turn my iMac G5 off, I just put it to sleep. SM is ALWAYS
running. Sometimes the machine wakes back up before I even leave the
room, sometimes I go away for an hour and come back and the machine is
awake with just the screen asleep. This has been going on since maybe
January (I do every OSX update the week it comes out and every SM one also).

I recently started quitting SM, and the problem seems to have gone away.
I know there's only a few OSX guys that read this group, could you try
duplicating my problem, or verifying if you are already "sleep prone
non-quitters"? ;-)

I used to have a problem where if I clicked "get messages" too soon
after waking the machine up (i.e. network conn not reestablished yet) SM
would crash the whole User Account. I'd have to log-out, log-in. That
has either gone away or I finally learned to count to ten in my head
before clicking anything.

Intel iMac Power Light

Mon, 25 Sep 2006 20:04:30 -0500

I'm sure the power light on my iMac used to be lit when it's on - it
only illuminates (flashing on/off) when in sleep mode. Is this my fading
memory or is it supposed to be like this?

iMac G5 powers down unexpectedley

Thu, 24 Aug 2006 17:50:20 -0500

The subject says it all. If I leave my iMac unattended for somewhere
between 2-3 hours, it will power down or crash. I'm not sure which,
since I'm never there to see it happen. There is nothing in the logs to
indicate the reason for the shutdown or anything suggesting a crash. I
have no Energy Saver setting that tells it to power down, nor are there
any schedules set. So I don't know what I should do. Any advice aside
from sitting next to it w/o touching anythin for 2-3 hours?
TIA

Energy saver schedule not working

Mon, 19 Jun 2006 10:59:44 -0500

If I try to set my iMac to power on/wake/sleep/power off using the
Schedule function in the Energy Saver system preference app nothing
happens. In all other respects I can sleep/power off ok, manually and
using an app like iWillQuit.

I have tried resetting the PMU, the SMU and deleting the plist file for
autowakeup. I have tried in Safe Mode with no other apps running as
well and got no joy. I have tried looking in the logs but to be honest
was not entirely sure where I should be looking and what for.

Before I try a clean install has anyone come across the same problem?

iMac G5 and Sleep or always on?

Fri, 16 Jun 2006 21:47:52 -0500

I sometimes have problems with certain USB devices
causing my iMac G5 to crash during sleep or restart. I find these
problems are eliminated if i set the mac not to sleep but to just
switch off the monitor. Do you think its bad to have the mac on all the
time?, also will it shorten the life of my mac if i shut it down alot?.

G5 iMac Fan Speeds/Temps?

Sat, 13 May 2006 02:38:11 -0500

I have a 20" Rev A G5 iMac. I wouldn't say it's overly noisy (I know
there were some rogue ones) but I'm a little surprised how much the fans
seem to have ramped up with the recent spate of warm weather.

Right now I'm seeing the following number using X Resource Graph:

CPU T-Diode 56.5 degrees C
Hard Drive 53 degrees C
CPU fan 2221 rpm
Hard Drive 3421 rpm
System Fan 2536 rpm

I'm assuming X Resource Graph is detecting the right sensors and
reporting correctly etc. but does this look about right?

I know there's a lot of variables but the Mac isn't doing much right now
and obviously there's no central heating on so it's just sat in a
"normal" room with the windows open - no load as such.

cheers,
Paul

iMac G5 crashes on restart & wake from sleep...

Tue, 02 May 2006 19:50:43 -0500

I have an iMac G5 (2GHZ, PowerPC G5 (3.1) running
tiger 10.4.6. Sometimes when the computer goes to sleep and I try and
wake it up by pressing any key nothing happens and after a couple of
minutes the fans come on full blast - I am forced to shut it down with
the power button and then restart.
A similiar problem happens sometimes when I restart
the mac, it just hangs at the black screen and no apple 'tone' is heard

as with normal startup, the fans then come on full blast - I have to
then restart as with the above example.
These problems only happen sometimes but are frequent

enough to cause concern. I believe the problems might be linked to USB
devices connected to the computer as on small scale testing it seems
the problems disappear when I unplug all USB devices except the
keyboard/mouse.
My current USB connections are keyboard/mouse, Nikon
Coolscan 5000ed scanner, epson photo r200 printer and canon powershot
usb cable. No firewire devices are installed but I am connecting to the

net via an ethernet cable.
Any advice/input on these issues would be greatly
appreciated.

many thanks,

Alex

Power draw of Intel iMac?

iMac G5 with narcolepsy

Fri, 24 Feb 2006 01:14:17 -0500

We've got a 17inch iMac G5 at work that keeps falling asleep in the
afternoons. No, really.

Symptoms are that it's making a wind noise like a gas turbine engine and
then will spontaneously sleep itself mid-use. Waking it up again, it
will usually immediate go back to bed.

All in all it's not dissimilar from myself.

Sounds like there's some sort of hardware fault (perhaps heat? cpu fan?)
and it's going into self-preservation mode. Is this something anyone
else here has seen?

iMac G5 fans misbehaviour

Sat, 18 Feb 2006 07:33:42 -0500

Of late - I don't how late - my iMac G5 has developed a nasty habit.
AFter being turned on, the fans will very slowly increase their speed,
first the System and Hard Drive fans, then the CPU fan. They appear to
settle at a speed some several hundred RPM above the minima.

This appears to be independent of:

User
CPU usage
temperatures
/Library/Preferences

Hardware monitor shows the temperatures falling to their minimum levels,
while the fan speeds continue to rise.

Also, the machine never wants to go to sleep any more.

Tomorrow I will try an archive-and-install to see if that helps. In the
meantime, please send a postcard with suggestions to the usual place.

iMac G5 brightness

Thu, 09 Feb 2006 09:05:19 -0500

I usually sit at the computer with all the house lights down and the
brightness set to no squares. I find that at full squares, the backlight
nearly sears my eyeballs out.

Even half brightness looks to bright to me.

Am I hampering the colour fidelity of the monitor by running it at a no
squares brightness? Will it make it last longer?
