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 8/14/06

Since 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!

  • Satellite A55-S1065 - After removing battery, BIOS ask me for password

    So, something happened yesterday, and it seems to me that this is very odd.
    I have a laptop Satellite A55-S1065. And while i was using power point, the
    computer freezes. So in the middle of my confusion, i decided to remove
    the battery just to make it turn off.
    So i did it and the plugged it again
    and tried to turn on the computer. Now the bios ask me for a password,
    but i have no clue what password is that. Can someone help me to fix this?
    Im really desperate to find some solution to this since this computer contain
    a lot of my works.
    Thank you so much.

    > After removing battery, BIOS ask me for password
    I know it sounds stupid now but I never heard about something like this. I use notebook for long time and I have made experience with many different and strange issue but something like this, never.
    Problem is that we discuss here in public forum and BIOS password is very sensible area and very important security feature so we cannot write here about some illegal ways how you can delete BIOS password.
    If there is no way to start your notebook I recommend you to contact nearest Toshiba service provider and ask for help.
    Sorry. :(

  • Lost the voice over bt function after removing battery

    I have a new Treo 800w and a new Plantronics 925 bt headset. I installed the voice over bt software, established a connection, and was able to use it to make voice calls (call john smith). I removed the battery to record serial numbers etc. When the Treo came back on, I reinstalled the voice software as advised. Now I can answer calls and talk using the headset, but I cannot get the voice commands to work again. I have not installed any third party software. Any suggestions?

    Not sure why you re-installed the software again after a soft reset. Taking out the battery and re-inserting the battery is a soft reset. See the instructions in the article below for the hard reset procedure.
    The program may have gotten corrupted when you installed over the top of the existing installiation.
    Here is the statement from the download page regarding re-installing the patch.Effect of resets on this softwareIf you install the Voice Dialing over Bluetooth Download and perform a hard reset, you will need to re-install the Voice Dialing over Bluetooth Download.
    If you install the Voice Dialing over Bluetooth Download and perform a soft reset, no action is necessary. The Voice Dialing over Bluetooth Download remains installed after a Soft Reset.
    You may need to uninstall the program and re-install. The fastest way is to Hard reset the Treo and then re-install. the hard reset will erase all data on the Treo, so make sure you sync before hard resetting.

  • MacBook Pro will not start after removing battery?

    My MacBook Pro has recently had a brand new battery put it, it's worked perfectly till now. My mouse was very loose so I decided to tighten it up. So I removed the battery, tightened the mouse and replaced the battery back (I've checked it's right) . However it now won't start up! At all, even when plugged into the mains. A faint flicking green light comes on the charger. Please help!

    good luck.....if all else fails, bring it to Apple and see what's going on with it.  Just don't let them know that you took the battery out.

  • Curve 8520 Won't turn on after removing battery.

    Hello, I've recently purchased a 8520, I've not had it for long but already it isn't working.
    I removed the battery the other day andante it back in, from this point... It will not turn on, when I charge it, it just shows as 'Charging'.
    Please help, It wont turn on, I've tried everything... Oh but also if I place someone else battery in, it works...
    I noticed some kind of 'Jump start' but never understood it.
    Thanks greatly ;D

    Try this: 
    Leave the device to charge 2-3 hours, and then, still connected to the charging cable, remove the the battery from the device a few seconds and reinsert it. If it boots--leave it to charge to 100% (check Options > Status for the percentage). If it doesn't reboot on the first attempt, leave it several more hours. I've had one charge for two days before it came back to life after an extreme battery depletion. Every 3-4 hours, with the device still connected to the charger, you can remove and replace the battery to see if it reboots.

  • Browser repeatedly stops working, even after removing battery

    For a few months, I've been encountering problems with my browser. It shows that it's loading, but never finds the page. I pull the battery out, wait a couple mins, then put it back in.

  • HT3053 I removed battery without turning off computer, now it will not boot up or eject cd

    I removed battery without turning off my mac book pro. Now it will not boot up or remove cd. I tried restarting with eject, spacebar, command e, option, trackpad, and f12 depressed, individually each time to no avail. I installed a 2 gb. ram kit and loaded OSX Snow Leopard after removing battery. I tried reinstalling the old ram with no luck..................Any help or suggestions would be welcome...........Thank You!

    And you eject the CD by holding down the mouse/trackpad button before powering up; that is, before the startup chime.
    BTW, if no startup chime or a different melody, RAM ist kaput.

    Polarity is really not an issue since there is a connector from the batery to the systemboard. It is either plugged in or not since there is a keyway at the header on the systemboard.

    My mac mini only shows a steady power light and fan noise when powered up. No video or sound and no commumication with wired keyboard or optical mouse. Tried replacing internal battery and resetting PMU/SMC but nothing seemed to happen.  Any suggestions? Many thanks! Richard

    You've already done the two things I would have suggested.
    If your Mini has an internal battery then I assume it's a G4. That means you've gotten a lot of good years of service from it, and it's old enough that it's certainly not covered by AppleCare anymore, and it's probably not worth spending money trying to repair it.
    You should be able to tear it apart using instructions from ifixit.com to get the hard drive out, and then put the hard drive into a nice USB or FireWire enclosure (I like the ones from Other World Computing, macsales.com) so you can transfer your data to a replacement Mac.
    I hope someone has another suggestion for you.

    Got the "apple firewire ntsc" choice to show up even if grayed out and "missing" under "audio/visual" menus by recreating choices in Easy Setup under "final cut pro" MENU thank GOODNESS because I was reading horror stories on here about this under another thread with someone trashing preferences, reinstalling and the works and still not getting it to show up...on my search now for an analog/digital converter up at b&h...find it odd that the s video connector wouldn't show the crt monitor when I put both displays through the 3870...I switched it back to see if it worked again when only the one dell monitor display was there and there it is again mirroring the screen display on my desktop...just can't be seen as an "external monitor" in fcp...couldn't find anything specific in the shane ross threads to this. I'm sad the program doesn't just see the s video connection though the 3870 though my computer does fine and will query up at b&h in regard to what might be affordable as far as a digital/analog converter. It's also weird in itself that when I put the two dell monitors on the one card my computer no longer could see the s video crt connection...makes no sense. Will report in later as to what I discover up at b&h as I'm sure there's a world of people out there using this sony crt monitor still even into the upgrades with computers and software so I imagine therein lies the solution. Thanks again and I'll report in as to what hardware might be suggested for me.

  • No sound and notifications working even after removal and fixing of battery

    All notifications including sound and vibrate are not working. I tried to rest the system by removing battery, but no luck. Please help in restoring the notifications.  

    Solution! 
    1) While playing the music: 
    2) Open the back cover, 
    3) Touch the connection buzzer on the back (right under battery location). I even now manage to apply pressure to the block-area without removing the cover, while playing music. Works! 
    4) Fixed!

  • After I reset PMU, my power light turns on ... but nothing else

    My computer was shutting down today intermittently
    actually it has been doing this for a month now, on and off
    so today I opened it up and thought I was doing the right thing by pushing that reset PMU button
    but now when I plug it back in
    the power light is bright but wont do anything else
    even when I hold it down
    it wont power off like it should
    any thoughts here ?

    That button should be pressed as part of procedure in these two documents.

    There are two because I don't know which model Power Mac G5 you have. If you have the earlier model and did not unplug everything when you pressed the button last time, I think that is an important part of the procedure. Since you already pressed the button once, you may want to use the alternate method of disconnecting everything and leaving it unpowered for a few minutes before reconnecting. When you reconnect the power, initially connect just the keyboard and mouse (leave the other peripherals off) when you try to start it up.
