PMU Info
Alright, I have seen a few postings about the reresting PMU and it working wonders, ex No more heat or it is much cooler, better battery life, fixes sleep problems. Now my question is why does this happen,? All of these can be LINKED to the PMU but also could be other software/hardware issues. I understand that doing the reset resets/balances the PMU out if it becomes out of sync, if i am correct. But that doesnt seem to make sense of how it fixes the heat issuse, since the heat is coming from the videocard and processor, unless that means both are getting less power?
Resetting the PMU doesn't always fix problems, perhaps it even seldom does. But it's easy to do, it might work, and it should be tried before more painful things like mailing the computer back to Apple. It's just that you do the easy stuff first.

Laptop mode tools problem with kernel 3.0
today I just updated the system and my laptop runs dramatically hotter after that. I read the archwiki, it does talk about the laptop mode tools problem with kernel 3.0 but when I opened the file /usr/sbin/laptop_mode, the lines which the wiki mentions are not there. Does anyone here have the same problem and can you offer the solution?
Here is my /usr/sbin/laptop_mode
#! /bin/sh
# Script to start or stop laptop_mode, and to control various settings of the
# kernel, hardware etc. that influence power consumption.
# This script is a part of Laptop Mode Tools. If you are running a supported
# power management daemon, this script will be automatically called on power
# state change.
# Configure laptop mode tools in /etc/laptop-mode/laptop-mode.conf, and in
# the broken-out config files in /etc/laptop-mode/conf.d.
# Please consult the manual pages laptop-mode.conf(8) and laptop_mode(8) for
# additional information.
# Maintainer: Ritesh Raj Sarraf ([email protected])
# Original Author: Bart Samwel ([email protected])

# Contributors to this script: Bart Samwel
# Kiko Piris
# Micha Feigin
# Andrew Morton
# Herve Eychenne
# Dax Kelson
# Jan Polacek
# ... and many others that I've stopped
# keeping track of.
# Based on a script for Linux 2.4 written by Jens Axboe.

# This is a 2 phase locking approach. LMT_REQ_LOCK is the outer lock and LMT_INVOC_LOCK is the inner lock
# We take this approach to ensure the scenario that, "At any point when an event occurs (AC/BATT), the
# kernel can generate multiple events spanning over a couple of events. The first event is honored and
# lmt executes. If the last event triggered at the 9th second, there is a fair chance that a good amount
# of state change would have occured in the OS, to honor that state, we keep an outer lock (LMT_REQ_LOCK)
# handy, so that those changes can also be applied and not forgotten.
# Workflow:
# Event-1 is generated and lmt executes (lmt runtime could span 5-10 seconds)
# At seventh second, 4 events generate. But Event-1 is still running.
# We don't want to discard all the remaining 4 events, but at least honor 1 so that we can act to the changes
# that occured in the last 7 seconds.
# So, Event-2 acquire LMT_REQ_LOCK and waits to acquire LMT_INVOC_LOCK (which is acquire by Event-1)

esacI had the problem but edited the line in /usr/sbin/laptop_mode and it worked. But thoes lines are not there anymore. I guess they changed it at the recent update of laptop-mode-tools.
Regarding your heat problem; is there any other thing you use to cut down power usage (from AUR maybe)? I use acpi_call from AUR had to edit lines there aswell, but it should be updated by now. -
I've had some power surges lately and now, my G4 FW800 won't turn on. The power button lights when pushed, but that is all.
I've reset the PMU, tried a different outlet and switched RAM in and out.
I fear the power supply is dead and, I hope not, perhaps the motherboard. Is there any way to determine this?
I think a power surge might be to blame, although the computer was connected to a surge protector and the computer was exhibiting some strange behavior the past couple of weeks (spinning balls, slow startup.)
I'm out of Apple Care warranty and would prefer not to have to lug the thing in some place...
Any suggestions?
- NolanHave checked or replaced the internal battery?
When mine went, I had no response from my Mac at all; just a light on my power button; absolutely no boot at all.
Check out things in Texas Mac Man's tutorial on the subject. His tutorial is a little dated (don't believe it even mentions G5's) but the info in it, except SMU not being included, still applies.PRAM and PMU info is in there too.
Cheers!

Reset PMU after removing battery
Is there a line missing in the instructions at http://docs.info.apple.com/article.html?artnum=14449 for resetting the Power Management Unit for the iBook G4 among others? They do not mention removing the battery and power cord. The instructions for several other Macs do say that. I could only get my new battery (from the recall) to start charging after resetting the PMU with the battery & power cord removed.
iBook G4 12 inch Mac OS X (10.4.7) New battery from recall on 8/14/06Since the iBookG4 1.33 mid-2005 model is similar to the
PowerBook 12" from that era, the procedure to do the PMU
is not surprising in its success, as you have found.
Even though the instructions do not say it, I read in a pdf
file where that is an option for the iBookG4 last model, too.
Good that you pointed this out, as the instruction is not
exact in this regard. ~ Thank you, too! -
PMU issue/ external hard drives aren't recognized
I've got a similar problem to an earlier post by CMORTON. My G4 has been acting up...it'll state that the time is set incorrectly and then my external hard drives won't be recognized when I plug them in. A couple of days ago I tried resetting the PMU, and that worked for a few days, but the issue has cropped up again. Any idea what I might try next?
thanks!Are you external HDs connected via USB or Firewire?

HELP - Missing Info For Dual USB iBook Display Repair
I've read and re-read most all of the discussions regarding the blank and/or dimmed display and pretty much determined that my problem is also due to a pinched wire in the hinge. The display is normal until I open it further than about 45 degrees, then goes blank. Sounds like the typical problem presented in this discussion.
I've got two questions that I can't seem to find answers to:
1) I bought the reed switch cable assembly from Small Dog as suggested in this forum (part no. 076-1073 (replaces part no. 922-5017) ). While trying to find some good instructions as to how to install this cable, I found that one supplier (powerbookmedic) says that there is a different part number for the 14.1" display (part no. 922-5451).
Can some one shed some light on this, since I haven't seen this discussed anywhere?
2) I've seen many references to the online take apart manuals such as that found at pbfixit or PowerBook Tech, but their guides don't go into the detail that I assume is necessary to actually replace just the cable. In other words, they take you to the point of removing the entire display only and leave you with the cables dangling.
If one wants to replace just the cable, where does one find instructions for that?
Right now, I've got my 18 month-old iBook feeding an old 17" monster Studio Display. Not exactly the notebook portability I thought I bought. I've spent a lot of time trying to find some answers to the questions above and I'm getting no where. Gawd help me, but having been through many, many Macs and one of the staunch Mac disciples since 1984, I'm actually finding myself hurtling toward the peecee world. Shame on Apple for making such a manufacturing boo boo in the first place, and then compounding their error by not fixing it!
Maybe I'll feel better if you can help me find the info I need to fix this thing.
TIA
AlThank you both for the excellent bedtime reading material!
This problem if far more widespread than I first thought. I can only think of all the folks who don't know about this Apple discussion group and have had this problem. Great PR Apple! In the past, I've sold many of my friends and cohorts on the virtues of Mac for many years, but am hesitant to do so from now on.
After finding that the 12" reed switch cable won't fit my 14" book, I decided what the heck, why not call Apple's SOS number before I get another cable and rip into this beast. The CS guy was trying to be helpful and suggested that I exercise my Disk Utility (I do that regularly), reset the PMU (I already did), and perform a Safe Boot (already did that too). I told him I was convinced that the wires passing through the right hinge were creamed and that I had demonstrated that by taking a small scribe and by moving the wires slightly, I could get the display to brighten momentarily at least until it was moved. My prime purpose for calling SOS was to find out if Apple had become so aware of this defect that they might be in the mood to correct the problem gratis. Also, since I live in the boonies, I'm at least 120 miles from the nearest approved Apple repair folks. (When I called them, they didn't know what a reed switch cable was and said they hadn't heard of any display problems. That left me with a totally cold feeling of distrust when it comes to letting them open my book up for surgery.) So, SOS said to try the aforementioned "tests" and assigned a case number. The guy apologized, but said from this point on any further discussion will cost me $49. That's pure bull!
I know I should just give in and get the stupid cable and perform the needed surgery. But, right now I'm pretty po'ed about this and think Apple should take some responsibility for creating this "feature". I'm feeling that I should just amputate the display at the hinges, hook it up to a big screen external LCD monitor, and buy a peecee book (that's hard to think about). At least then I could enjoy all those things and sites that won't play with Macs. YIKES!
Thanks again for all your help!

Cannot find Battery Info in System Profiler
Cannot find "Battery Info" in System Profiler (4.0.4).
Originally, I was going to title this post "battery not charging" - which is why I am looking for battery details. Of course, as soon as I started typing the battery clicked up a notch (29% to 30%).
So, I got a confused battery and a confused System Profiler.
A couple of weeks ago I had drained the battery completely and had to even run off the backup battery as I quickly finished what I was doing. I had since fully charged the battery and thought there were no problems.
Then suddenly a couple of days ago, I looked up and it was stuck at 33%. When I tried to switch from "Percentage" to "Time", all I got was a "Calculating...", which it never actually did. I tried unplugging the computer, and it indeed did run off battery power, so it was at least communicating power-wise, if not information-wise. Two days of fiddling around offered no solutions. (Zapped the PRAM, reset PMU). Meanwhile the battery kept on not charging.
Then, I start typing here and suddenly the battery is communicating with the computer. Percentage is ticking up and there is even an estimated "time until full". However, System Profiler still does not see any battery, or in fact even give me anything to click on for power management. It's not under Hardware, Software, Network or Logs. "Extended Report" doesn't find it either. I'm hoping I am just missing it somehow... is "Battery Information" hidden somewhere?
The battery plug has now switched from green to orange and the indicator icon from a battery with a plug, to a battery with a lightning bolt. While I was trying to figure out the problem, I have taken out the battery several times, so I doubt it would be a simple connection issue.
While I would like to believe my computer has magically healed itself, I suspect that something is still amiss. Maybe earlier versions of System Profiler did not have Battery Info?Hi, RW, and welcome to Apple Discussions. System Profiler prior to the version that came with Tiger doesn't report any battery info. If you're running Panther, that's why you can't find anything about your battery in SP. Jeremy Kezer's XBattery will provide info about your battery in Panther.
Test to see whether your battery charges with a different, known-good AC adapter. That's the cheapest component of the charging system to replace if yours is faulty, and with luck that will prove to be where the problem lies. Other possibilities are a bad battery, DC-In board, or logic board. -
Computer not getting info from mp3
I hope someone else has had this problem. All of a sudden my computer is not displaying any of the info in my zen moziac. I need to make space, arrange playlists and all the software ( both creative central and windows ) does not show the info in my mp3. It only seems to show some recent stuff i loaded to both computer and mp3. I have playlists and it shows only one in the mp3 and 3 in the computer. So in short I am unable to view all of my info to delete add or rearrange.
Are you using the factory charger or a 3rd party? I used to have a 3rd party charger that would not wake my powerbook from sleep. The only work around I could find was to pull the power and battery, then wait for the sleep light to stop flashing (5 minutes or so), plug the power and battery back in, and then it would boot (though at that point it is no longer "sleeping" and will perform a cold boot). Another option would be to try resetting the PMU. If memory serves me correctly, you removed power and the battery, hold down the power button for at least 5 seconds, then reapply power and boot.
Good luck.

Pismo shuts down while asleep. PMU cause -96?
Hi. My Pismo has recently started to shutdown unexpectedly while asleep. Since it's intermittent, I can't really tell if it realy goes to sleep and then shuts down or if it just dies when I close the lid, but not only MacOSX took notice of a forced shutdown (and offered to report it to Apple, but the CrashReporter never came up), it also had a line in system.log with "localhost kernel[0]: ApplePMU::PMU forced shutdown, cause = -96".
Now, I know that ApplePMU messages seem to be some kind of state secret at Apple and that several guys with G5s are having problems with cause -122, but does anyone have any experience with this?
I've only been noticing it lately because I have a new battery and now I keep it sleeping far longer than before, because my old battery only had 5 minutes of life in it and this Pismo was basically chained to a wall.
Powerbook G3 Firewire Mac OS X (10.4.5) 1GB RAM, 40GB HD, AirportTiago,
I don't know what the error -96 represents, but I have seen the same PMU Forced Shutdown with numbers like -122 and -127 (again, no info).
I would reset the power manager and PRAM, then test.
You mentioned not knowing if it crashes or shuts down immediately; if you see the pulsing sleep light, it still is sleeping normally.
Does this issue occur only on battery or also when connected to the power adapter? -
I'm fixing up my old Wallstreet ( 512 RAM and 30GB HD) and trying to get OS X running. I think the hardware is straightened out (7.8 GB OS X partition, rest OS 9 and OS X data) and finally found the stick of RAM going flaky when hot. Now I have a PMU problem. Works fine under OS 9 and worked under OS 10.2.1. When upgraded to 10.2.8, then shut down, the system won't stay awake, that is, it boots but when it reaches the desktop it goes to sleep and won't wake up. Restting the PMU (shift-fn-ctrl-power) shuts it off and then it won't restart at all. To fix this, I have to pull the plug on the backup battery, which requires a complete disassembly and is a royal PITA!
This happened to me before on an iBook (white dual USB 500 MHz) when I did the 10.2.8 upgrade. Since that machine was under warranty at the time, I took it back to CompUSA where I bought it, and they destroyed it trying to make repairs. (Long story which came out OK in the end.)
Anyhow do any of the Wallstreet experts know another way to cause the PMU to reload its code other than disconnecting all power including the internal battery? I've tried "reset-all" in Open Firmware, and that just resets - not reloads the PMU processor.
Any hints to avoid trashing the PMU's memory on upgrades? Normally they go without a hitch, but this one has bit me twice.
iBook 800 MHz, Wallstreet G3 292 MHz Mac OS X (10.4.6)William,
The failure to power up, or if it does start but then immediately sleeps after the desktop loads reminds me of a problem peculiar only to the Wallstreet that was common in the earlier days of the Wallstreet. Users were replacing their HDs with larger ones (10-30GB at the time) and experiencing these problems:
- Once the HD was installed, they could load software and everything ran fine, but the first time the display was closed when running, it would not wake, or if the display was closed with the powerbook turned off, it would not start up.
- Sometimes the 'book would power up but immediately go to sleep.
- Sometimes pressing the power button produced a buzz when the 'book was not responding.
- Depending on the particular HD, this issue could be intermittent.
With most of these symptoms, the cause was the HD's magnet interfering with the magnetic sleep switch located in the side rail next to the 'delete' key (and next to the HD). Once put to sleep, for example, the HD would prevent the sleep switch from opening (if the display had been closed).
I am guessing that by disassembling the powerbook to get at the PRAM battery, you also removed the HD...this would have released the sleep switch.
There are several quick ways to test for this problem:
- when there is no response, remove the HD, then reinstall;
- tap the side rail with the handle of a screwdrive or something similar;
- try a refrigerator magnet above or below the side rail (I would be careful here).

Resetting the PMU. How with my kind of Powerbook?
Hello,
I have the problem, not to know, how resetting of the pmu is done with my Powerbook G4 1,25 Ghz bought in December 2003.
I already read the article that is posted at the Apple Support (http://docs.info.apple.com/article.html?artnum=14449
), you even mentioned. But I cannot follow the instructions, because I think, the right type of Powerbook is not listed.
So it would be nice, if you can help me with this problem.
Thank You.Your PowerBook is listed as: PowerBook G4 (15-inch FW 800)
15" 1.25GHz/12" 1GHz PBs, 2xPPC Mac minis, 12" iBook G4, Mac OS X (10.4.6) Cube, 2xTAMs, iPods 2G/4G, iPs, AEBS, AX -
I am having power issues, talked with Apple Care today regarding the power component problems (my iMac is of the first lots made in Sept of 2005). My first step is to reset the PMU, and the apple care guy told me to go to a particular troubleshooting page under the "computers and servers" part of the main support page so I could reset PMU myself later in the day. I didn't notice while I was on the phone with him that the article mentions only an internal power button and an SMU button. Is the SMU button the same as the PMU button on my iMac? If not, where is the diagram for the PMU button? Thanks!
BTW, the article is located at http://docs.info.apple.com/article.html?artnum=300908
iMac G5 Mac OS X (10.4.6)
iMac G5 Mac OS X (10.4.6)It is much better to shut it down normally than to have to "force quit" regularly, toothfairy. You should actually run Disk Utility and "repair disk" while booted from your MacOS DVD, or start up in "Safe" mode, after EVERY forced shutdown to repair your directories. Even though you probably won't hurt the hardware there is a very good chance that you WILL damage your data if you keep on following the "forced shutdown" route.
But have a look at some of the other "sleep" issue threads here. It may be that you simply have a problem with one of your peripherals needing up dated drivers , or a bad USB hub or modem, for example.
You may also find that the computer will wake properly if you actually put the computer to sleep manually, using the Apple menu, rather than letting it fall asleep by itself, by the way.
Cheers

Hello,
I was having a problem with my iMac G5 yesterday. After calling tech. support, they had me do a PMU reset which apparently fixed the problem and OSX loaded with no apparent problems. Except, when my our logins came up, our passwords did not work. Mine nor my wifes. Any suggestions? They told me to bring it to an Apple store...Hi vallon, you might want to try the process described at http://docs.info.apple.com/article.html?artnum=106156 for "Resetting the original administrator account password"
Cheers

10.5.5 and PMU reset locks Hard Disk!
I upgraded my PB G4 12 from 10.4.11 to 10.5.5 and right away I noticed a drastic
shortening of battery life. I reset the PMU and now the HD is locked. When I attempt
to copy or create a new document a message appears stating that there is no space.
available
Even though there are 23 GB of data, The HD Info window shows
Capacity: --
Available: --
Used: Zero bytes on disk.
I attempted to repair permission, but to no avail.
Should I go back to 10.4.11?I get dozens of the "ACL found but not expected ..." messages, all on the contents of System/Library/User Templates/. When I go to System/Library/ in Finder, only the User Templates folder has a red icon on it, indicating that I do not have access to it (when logged in as an admin). The icon does not appear on any of the other folders in System/Library. Does anyone have any idea on what's going on?

I reset PMU, and now, no startup...
Greetings, all. I turned off my computer, pulled the power cord, hit the PMU button, shut the door, attached the cord, and waited ten seconds and then hit the power button. And now the computer will not startup.
One thing to point out is the I was experiencing kernal panics as the only functionality of the system, and so I replaced the internal drive. The internal drive does not have an OS installed...but I do not believe this makes a difference, as hitting the power button yields no results at all.
Any suggestions?
Thanks!
VinceIs there any indication that it's trying to start?
Based on your description, you followed the procedure in this document. *Resetting Cuda/PMU on Power Mac G5, Power Mac G4, Power Macintosh G3*
http://docs.info.apple.com/article.html?artnum=86760
Hopefully, you didn't press the PMU button more than once, because this can cause the internal memory battery to discharge quickly. You need to check the voltage on the battery. See Mac PRAM, NVRAM, CUDA/PMU & Battery Tutorial
KPs are usually caused by hardware problems, frequently RAM. Disconnect all external devices except your mouse, kbd & monitor when troubleshooting.
