Odd sleep behaviour on MacPro

Sun, 17 Oct 2010 07:21:50 EST

I have X windows running on the Mac. Windows come from other systems,
displayed on the mac (as well as some local xterms).

Usually, when the Mac goes to sleep, the displays go off, but the
ethernet remains on and enough of the Mac remains awake to maintain the
remote x window connections.

But every now and then (I think it is after a reboot), going to sleep
results in the ethernet going off which causes all the remote X windows
to timeout and be lost.

Energy saver is currently set to:

Computer sleeps: 1 hour
Display Sleep: 12 minutes

Put the hard disk to sleep: yes
Wake for Ethernet network access: no
Allow power button to put computer to sleep: yes
Start up automatically adter a power failure: YES

Note the later: after a power failure where the mac was asleep, it does
not power back on automatically.

I haven't changed those settings in ages.

I suspect some application, possibly Transmission (for torrents), does
something to the mac to prevent it from ever going to sleep completely
and this survives after Transmission has quit but is not reflected in
the System sesstings.

is this possible ?

Is my only option to set the "Computer Sleep" to "Never" ? is there a
"half asleep" setting where background stuff continues, but GUI stuff is
suspended ?

I'm not sure if it can survive past Transmission being quit, but there
*is* an option to turn off Transmission interfering with your settings
entirely in its Preferences (Network tab).

"Prevent computer from sleeping with active transfers"

The wording would tend to indicate that even with transmission running,
it would still go to sleep if there were no active transfers. Perhaps
the setting is so strong that it survives not only the lack of active
transfers, but the quitting of the application :-)

Unexpected Sleep

Fri, 03 Apr 2009 02:59:13 EST

Hi ! I have an Unexpected Sleep bug during "Installation - with
Installer.app".
Essentially what appends is (I'm on a beige G3 - old rom, running
MacOS 9.2.2
and MacOSX 10.1.5 ) after upgrading to 10.2 - 10.2.8 it sudently goes
to deep sleep
without any response. I dont' know if I had to (because I did
repartitionned my drive, I'm within the 8 gig, did a clean wipe-zero
thing and starting the installation from 10.1 CD) install 10.1.1 or
more to go directly to 10.2 and then 10.2.8 combo, etc.

Have any clue on that bizarre behavior ? I know that it's the late
upgrade (Jaguar - 10.2) that old rom beige G3 are capable, but to
which extend it goes : 10.2.3? ...5? ...6? or ...8?

Thank you on that, it'll help go back to sleep...

Fan activity with Leopard

Thu, 19 Mar 2009 21:33:55 EST

Hi,

iMac G5 without iSight + Leopard 10.5.6

Since I've made the upgrade from Panther 10.3.9 to Leopard 10.5.6,
I have noticed that the Fan activity is bigger, there's much
more noise and they runs Faster ...

Is it because Leopard needs more power from the CPU ?
(in comparaison with Panther)

What's your experience / feedback ?

TIA,

Thierry

CPU too hot

Wed, 18 Mar 2009 06:03:43 EST

Hi,

iMac G5 + Leopard 10.5.6

When my iMac G5 works in a very intensive way,
it switch suddely in the sleep mode.

It didn't happend under Panther 10.3.9

I think it happend because the CPU is too hot.

Do you know if it's possible to stop this switch ?

TIA,

Thierry

Mac not sleeping

Thu, 26 Feb 2009 16:26:47 EST

My Mac seems to sleep ok manually, but not via Energy Saver. at any
rate, the fan seems to be on (with screen black) if I leave the machine
unused for an hour or two.

I'm pretty sure I know the reason. I stream music to my hifi using a
Squeezebox (wireless hardware) and SlimServer. As SlimServer is a
server, I assume that Energy Saver does not want to sleep the machine if
SlimServer is active.

I'm wondering if there is any third-party software that will ensure the
Mac sleeps when I am not using it. As far as I an concerned, I would be
happy to wake the machine manually when I need to stream music.

Powerbook battery question

Sun, 04 Jan 2009 02:23:33 EST

I've Powerbook G4 and would like to know if running it with the battery
out (on AC power) will do any damage? I'm aware of the limited cycles
that a battery has and as I tend to use it only with AC power would like
to preserve the battery's charging ability as long as I can.

If this is not a problem, can I remove/insert the battery safely when
the machine is plugged in?

The reason I ask is that with my Toshiba (running XP Pro) I tend to run
it always on AC power but disconnect it when removing/inserting the
battery. Is the Mac different from this? I know that I lose the clock
time when the Mac is not plugged in (in contrast to the Tosh which
doesn't seem to lose clock time).

One more unrelated question...
I'm running OS X 10.3.8 and every time I start the Powerbook the Hard
Drive icon moves to a different place on the screen. Is there any way
of keeping it in the upper right hand corner where I prefer to have it,
other than at a random place upon boot up time?

Thanks,

Karen

iMac G4 running hot

Wed, 31 Dec 2008 11:46:40 EST

My mother is visiting me for a few weeks, and I have set her up to use
my old iMac G4 while she's here. All she's doing is email and a couple
of games (Snood, mostly, some Bejeweled 2), but after an interval of
time that seems to be getting shorter, the computer will overheat and
shut itself down. Sometimes it has to be unplugged and plugged in again
before it will restart (even after allowing time for it to cool down).
This can't be good!

iMac G4, 768meg, running Leopard (10.5.5, I think). I'm not even sure
what to start looking at to figure out what's wrong, so any suggestions
will be gratefully accepted, either via email or here in the group.
It's not a serious problem but it's frustrating for her.

Thanks in advance for any suggestions!

Reconnecting on wake from sleep

Tue, 03 Jun 2008 03:50:01 YAKST

Being a total newbie at these things, I'm rather proud of having got my
Airportless mini (running Panther) set up with a Netgear USB wireless
adapter and the Realtek driver. But the mini tends to drop the
connection when it wakes from sleep. (I expect it dropped the connection
when it *went* to sleep, but you know what I mean.) I can re-establish
the connection by physically disconnecting the adapter and reconnecting
it. But is there a way of doing this virtually, via the keyboard? I
mean, of course there is, but could someone please tell me what it is?
Thanks.

G5 Roars Out of Control

One possible cause is bad memory. I once had a PowerMac G5 that crashed
repeatedly with exactly the same symptoms that you describe. No hardware
or memory tests were able to pinpoint the cause, and an Apple-certified
technician ran it for days in his shop without managing to diagnose the
problem.

I later bought some extra memory and did some swapping until I found that
the crashes were always associated with one particular DIMM, and they
ended when that DIMM was removed. The technician confirmed my diagnosis
and got the memory replaced under warranty. The bad DIMM was from Apple,
but the extra memory I bought was third-party and worked fine.

USB mouse wake from sleep

Is there a way to stop a USB mouse from waking a sleeping Late 2007 MacBook
using Leopard?

TIA

Weird one... (couldn't unlock from sleep)

Sat, 03 May 2008 06:58:59 YAKST

I hate it when there are irreproducible faults, although in this case I
guess it's better than a permanent serious one. I went to wake up my
Powerbook G4 (running 10.4.something), which I have set to require a
password to wake from sleep. I enter my password and it tells me wrong name
or password. OK, must have mistyped (that first character getting lost
sometimes thing maybe.) Didn't work. Tried a couple of more times, typing
very slowly. No joy. Eventually got the "failed too many times" error.
OK, I have a couple of other accounts on the machine, so I told it to switch
users and tried a different one. Same problem -- wouldn't take the password
and eventually got the "too many times" error. Wondering how I'm going to
recover from this (envisioning I'm going to have to find my master password)
I shut it down by pressing and holding the power switch -- at least that
worked! Restarted and everything's fine. Go figure.

MBP battery performance in Leopard?

Thu, 27 Mar 2008 02:50:04 EST

Anyone else noticed significantly worse battery performance since
upgrading to Leopard? My MBP seems to have lost about 45mins of life...

Closed Lid Operation

Tue, 11 Mar 2008 23:24:55 EST

All,

I generally use my laptop (15" MBP 2.4GHz, 4Gb, 200Gb) as a desktop
replacement. I have an older 23" apple cinema display (acrylic) and a
standard aluminum keyboard and wireless mighty mouse. Since I upgraded
to Leopard I can no longer simply hookup my power, DVI, and usb to
reliably boot with the lid closed. 90+ percent of the time, I end up
with the dispaly on the MBP turning on, going through the "gear"
screen with the Apple log, and then kernel panic. If I leave the lid
up, it boots into dual screen mode. Afterwards if I put the machine to
sleep, close the lid, and hit the keyboard to wake up, the laptop
display comes on and the external monitor powers back up with a black
screen and sits there until it goes back to sleep. If I move the mouse
over to the 2nd display, it appears as the beach ball of death.

I have run through removing all usb devices, using different keyboard/
mouse combinations, no firewire conected, and most other combinations
of only a mouse, keyboard and display connected. I have also reset the
SMC module, and so far the only thing to make this work reliably is to
boot my old 10.4.11 image.

This is a quite frustrating, any thoughts/suggestions?

Thanks

Battery Life and Leopard

Fri, 25 Jan 2008 23:12:55 EST

Hi everyone,

I was just wondering if anyone else has noticed a drop in battery life
with leopard installed. I have an original core duo macbook so the
battery is aging anyway and im wondering if im imagining a sudden drop
in life after installing leopard or wether the battery is just on its
way out.

Cheers

Powerbook G4 - kernel panic on sleep

Sun, 20 Jan 2008 08:34:32 EST

G4 1.67, 2gb, running 10.5.1

It's happy to go to sleep IF it triggers this itself; but if I close
the lid - or select 'sleep' - it almost immediately throws a kernel
panic. This is NOT happening when it wakes up - it's before it actually
sleeps... except when it chooses to sleep itself!

Anyone any ideas? Please?

Power-Line Ethernet: How Secure? Interference?

Sun, 13 Jan 2008 04:58:45 EST

How secure is power-line-based Ethernet? Does it hose up radios and
such? I'd think that it would "radiate like a banshee" as one of my
former coworkers used to say.

sync before sleep

Fri, 21 Dec 2007 19:57:59 EST

Hi,

... can anybody tell me whether Mac OS (Leopard) does a sync before I
send it to sleep? I ask because the Time Machine disk may potentially
get disconnected during the sleep period. I know this is generally not
a good idea but I want to know if I have to definitely unmount it
first. I know that it probably complains about a disk being removed but
not unmounted first after waking it up again but if it's sync'ed then
this shouldn't be much of a problem.

Sending the Mac to sleep and waking it up with the disk mounted is not
a problem. I've tried that and it doesn't complain and everything seems
to be fine so far.

So what if the disk is removed during the sleep period?

Sleep weirdness

Fri, 07 Dec 2007 09:49:17 EST

I have a client running 10.3.9 on a G5 iMac (no iSight). Every time
the iMac goes to sleep, it won't wake up. When you tap the spacebar
(or any other key or the mouse) the iMac shuts down instead of waking
up. It powers up fine, all the diagnostic LED's are lit. I did a
preference-ectomy, zapped PRAM repaired permissions, all to no avail.
I even created a new, virgin user account, which behaved exactly the
same. Has anyone run across this? Is there a solution short of erase
and install?

Many thanks!

Wake up problems in Leopard again

Mon, 26 Nov 2007 22:55:55 EST

I went to the Apple site to see what wa there in regard to wake up failures
on my G4. Iam far from alone. There have been about 100 posts on the
subject--all very similar. It is not just a G4 that is the problem.

With the computer in the sleep mode, pressing any key should wake it up.
That is not always the case. After fiddling around, I am convinced that it
is a software problem. Pressing a key does indeed get picked up b the
computer. The fan turns on, the mouse lights but the keyboard gets
disconnected. That is, after then initial activity to wake up starts, the
keyboard is not served by whatever USB should do. This does not happen every
time the computer goes to sleep.

What does it take to get Apple's attention. I looks like Apple expects their
customers to provide the technical support Apple should.

Wake up problem with Leopard & twin processor MacG4?

Fri, 23 Nov 2007 12:54:43 EST

This is a corrected (I hope) and supplemented repeat of a previous post. I
apologize for what seems my growing ineptitude.

Only sometimes, my G4 running Leopard 10.5.1 (and original 10.5.0) does not
wake up properly. I am using a USB Apple keyboard with a Macally mouse
plugged into the keyboard.

When I press a key, the mouse lights up but I have no control from the
keyboard or the mouse. The screen remains dark. The pilot light in the power
button does not vary in intensity as it does during normal sleep.

The caps lock key does not light up when pressed.

If I unplug the mouse from the keyboard or unplug the keyboard and replug,
the mouse light does not turn on.

There is power on the USB cable that I use because I can light up USB
powered speakers. That power is not available during normal sleep.

If I press the power button long enough to turn off the computer and reboot,
everything seems to be OK.

I had the same problem just before posting this supplement. I confirmed that
the pilot lamp was brightening and dimming on about a five second cycle
while computer was asleep. I pressed the caps lock key once. The pilot light
steadied. The mouse lit up brightly and then went to its standby intensity.
I heard the fan in the computer start up again. It was deja vu all over
again. There was no control from the keyboard and the screen was dark.

I conclude that there is something going on in Leopard that keeps USB
devices from being serviced correctly. What can that be? How can that be
corrected?

iMac won't stay asleep.

Tue, 20 Nov 2007 20:30:19 EST

Hi all,
Since installing Leopard, my aluminium imac won't stay asleep. Sometimes
it wakes up instantly, and sometimes it wakes up after about 10 minutes. The
culprit seems to be my Apple bluetooth keyboard. The iMac is set to allow
bluetooth devices to wake it. When I sleep the mac, the keyboard goes into a
low power mode which then wakes the mac. If I use a wired keyboard the mac
will sleep normally. If I turn the bluetooth keyboard off before sleeping
the mac, it behaves normally.
Any tips?
Thanks. Andy.

Mac doesn't wake up from keyboard

Sat, 03 Nov 2007 02:09:23 EST

Since installing Leopard my Mac Pro seems less interesting in waking
up from sleep. It used to be that the first press of mouse or keyboard
would do it, but for the last two days it seems to ignore this, and
only a press of the front-panel power button will do it.

Is there a new pref for this somewhere? Anyone else seeing this?

MacBook Pro spontaneously wakes from sleep after upgrading to Leopard?

Thu, 01 Nov 2007 16:28:47 EST

For some reason, after I upgraded to Leopard, then whenever I put my
MacBook Pro to sleep, it spontaneously wakes up after some time (can
be from a few minutes to an hour or two.) I don't know why this is
happening, but I know for sure that it's related to Leopard since I
put my laptop to sleep every night (it's in my bedroom) and after
upgrading to Leopard, it started to just wake up a short while after
putting it to sleep.

At first I thought it could be Time Machine, so I disconnected all my
external drives, but that didn't seem to work.

Does anyone know why this is happening?
Thanks in advance!

[ANN] Power Manager 3.7 - reduce your carbon footprint

Tue, 30 Oct 2007 04:57:47 EST

DssW today announced the launch of Power Manager 3.7 for Mac OS X. Power
Manager 3.7 introduces support for Mac OS X 10.5 (Leopard), a new wake
action, and time zone support.

Power Manager 3
<http://www.dssw.co.uk/powermanager/>

Download Power Manager 3
<http://www.dssw.co.uk/powermanager/download.html>

Power Manager now supports a wake up action to complement the existing
'start up or wake' action. The new wake action improves Power Manager's
flexibility when used with a typical office schedule. If a colleague is
sick or away, their Mac can be shut down without needing to consider
Power Manager. Their Mac will remain off, saving energy until the next
scheduled start up event. This improvement helps Power Manager better
fit a busy office environment.

Power Manager 3.7 introduces time zone support. When a Mac's time zone
changes, Power Manager immediately updates the schedule to ensure
scheduled events occur as expected. Time zone support ensures Power
Manager is both a good travelling companion and suitable for global
deployments. This improvement particularly helps Power Manager users who
frequently travel with their laptops.

Power Manager 3.7 includes other improvements and bug fixes detailed in
the release notes, including improved documentation, status menu, and
Quick Schedule.

Power Manager helps schools and businesses save energy by automating Mac
computers. Users can schedule their Macs to start up or wake, shut down,
restart, log out, switch to the login window, wake, and sleep.

Power Manager scales from one Mac to ten thousand with ease and is
suitable for managed environments. Power Manager 3.7 includes an
administrator guide and bug fixes that ease network deployment.

Pricing and Availability

Power Manager is available today through the DssW web site
<http://www.dssw.co.uk/powermanager/>, for EUR20 (US$29). Scaled
discounts for +100 Macs are available. System requirements are Mac OS X
10.3.9 or later.

Version 3.7 is free for users of Power Manager 3.

Gremlins? Is it a coincidence that the same thing started happening to
my kid brother's G5 iMac the day before yesterday? Even though his is
still under AppleCare, he couldn't afford to be without it for the few
days, so he moved his Intel iMac purchase up a few weeks (was going to
buy after Leopard came out), did the Migration Assistant thing, and
took his in for service -- we should know the cause in a few days.

I had a similar problem with a Wintel box and a PowerMac G4 a few years
back -- in both cases it turned out to be power cords/plugs that just
weren't seating properly. That's now the first thing I check.

Running Mac OS X 10.4.10 on a MacBook Pro 15" (Intel Core Duo)...

When running off the battery: At 40% remaining, the machine goes
black and shuts down completely. There's no warning or low battery
alert. The computer is *not* asleep; a hard reboot is necessary to
bring it back to life.

We have attempted to condition the battery by putting the Mac into
sleep mode until there's no more juice, and then completely recharging
the battery. Despite this, the problem persists.

Does this mean that we need a new battery? Or is something else going
on here?

Many thanks!
