Battery on iBook G4 running down when computer shutdown??

The battery on my 2004 iBook G4 runs down even when computer is shut down. I have looked at the
energy preference but can't figure out what is triggering the computer back on to do this. There is
nothing in preferences set to turn the computer on.

First you say that the battery runs down while the computer is shut down.
Then you say that the computer comes back on.
Which is it? Does the computer start up all by itself?
Have you tried resetting the PMU? The PMU (Power Management Unit) has control over both the sleep and charging functions, so resetting it may help.

Ibook G3 shuts down when power cord is inserted.

You may have to consider having the computer checked to see if
the DC-in circuit is working properly; could be that is where things
are going wrong. If you had a spare battery and an external
charger (such as some companies offer for their iBook replace-
ment batteries) you could run it for some time before needing to
do some repair, maybe.
For out of warranty repairs, you can check with Tech Restore, PB Restore
and other named companies who offer authorized/certified repairs online. I
had good service and was able to contact wegenermedia about my iBook
repairs before and after the service, which was very satisfactory.
PS: And one assumes there was a reliable power supply on the
AC adapter's power-in; and the adapter has a proper voltage out.

Fans running faster when computer idling

I installed Snow Leopard on my late-2008 MacBook Pro a week ago. It has been running fine except for the following. At night, I leave my mac on to download torrents using Vuze. I lower the screen brightness to zero, and disable the energy saver features. The computer has been getting hot, and the fans really spin fast. It never did this with Leopard.
Funny thing is, when I raise the brightness and actively use the computer more heavily (Vuze running in the background, other apps also running), it cools off and the fans spin down.
Any ideas on what's going on here?

ITunes shuts down when computer sleeps

Run script when system shutdown

Hi Community,
I know the possibility in snow leopard to execute a script during system boot by using a launchd script located in /Library/LaunchDeamons or ~/Library/LaunchAgents but how can I configure a script which become executed on a system shutdown?
Thanks in advance & Bye Tom

Well then that is /etc/rc.local.shutdown that I believe you want. It won't trigger a shutdown, but on next restart, your commands will have been done. I just made a text file for /etc/rc.local.shutdown to cp from one file to another. Then I restarted manually and file was copied.

APE drops internet when computer shutdown/sleep

I currently have 2 Macs and 1 PC all connected wirelessly to APE (n mdoel), which is hooked to a DSL modem.
The problem is whenever one of the machine shutdown or go to sleep, APE would drop the internet connection and it would start the amber blinking light. The AirPort Utility then also complains that it has lost the internet connection. After a minute or so, it would reconnect the DSL by itself and everything is normal until another machine shutdown/sleep again.
Anyone know what's going? It's really annoying to get disconnected like this! Thanks

Try creating a new Location under System Preferences->Network and then switching to that location and using it ? It has worked for some folks in the other threads.
Also stick to using WPA2-Personal only. If you have VMWare etc., try disabling it and see if it works.

Macbook air energy usage - battery runs down whilst sleeping

I have a July 2013 Macbook Air and the battery seems to be running down quickly (more so while it is sleeping, the usage when awake seems to go down at expected rate).
I have taken it to apple genius bar who said the battery was fine and did a fresh install of 10.9.2 (I then restored my time machine backup). They ran a diagnostic and said battery was fine.
There are no big active processes under activity monitor and power nap functionalies are disabled.
The battery runs down over the course of one day if asleep and just now it dropped by 10% in an hour while asleep (closing the lid or going to apple and then sleep makes no difference).
It did seem to start suspicously around the time I upgraded to Mavericks so I feel it's a software issue....
Any ideas?!
Thanks so much
Alexis

Tami ...
I turned off any automatic updating, stopped Sophos Antivirus from on-demand scanning.
Regardless of turning off updating ..... a/v software on Mac can cause a litany of problems.
Uninstall the Sophos a/v software > Removing Sophos Anti-Virus for Mac OS
Then restart your Mac to see if it makes a difference.

Macbook shuts down when plugged

I have my macbook for 2 years, and last month it started to behave in a weird way.
First when I let the battery drain out it shuts down when the battery reaches around 2-3%, it doesn't go into deep sleep. I've checked the battery capacity and it's around 2852mAh, and the check battery sign just started to pop. I'll probably have to buy a new battery. (That doesn't bother me much, because I use it mainly plugged on power.)
But last week it has gotten worse, now my macbook started to shut down when it's plugged. It takes a minute so I can reboot it (not even the battery indicator works for a while), and the charger stops working right after it's off. I'm using a new 85w charger (the old one got ripped off), because they don't sell the 65w here in Brazil. Needless to say I've tried do reset the SMC, PRAM, NVRAM.
Ps: On january I upgraded my RAM with some used module I got from buddy of mine.
Pps: You should know that there's no apple store in Brazil. Don't tell me to ask the genius :P

I took my macbook to a apple technical support provider, and they're replacing my charger. I wonder if the faulty charger could have damaged my battery, the check battery sign first appeared after the shutdowns caused by the charger.

Why has my iBook started to completely shuts down when power runs out?

I purchased my iBook G4 in early 2006 (OSX 10.4.11)
Until last week, I would regularly use my laptop until the battery charge was used up. I would get a low charge warning and it would automatically sleep. I could then plug it in to charge. When it was plugged in, I could touch the track pad or power button and all of the programs that were open when the power ran out would be there, just as I left them.
This has recently changed. Now when the power runs out, I receive the same low charge message, but instead of sleeping, my computer completely shuts down. When I press the power button to reboot, everything starts back up fine, but I get a message that my date and time are off and need to be reset. I then go to the Date and Time menu, which automatically updates through my wireless connection.
My questions are:
1. Why is it shutting down instead of sleeping?
2. Why is my date and time reseting to an incorrect date and time?

The difference is that in the past, your battery shut the computer down when their was enough juice to safely sleep the machine. Now it thinks it has enough juice, but it's truly running out. The battery is necessary to maintain the date and time in the computer.
Your battery needs to be calibrated. You should follow the instructions at:
http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh1959.html
This will allow the battery to truly know how much juice it has left.

I bought a ibook G4 2005 refur-ed it is making a fan running noise when I listen to sample music on line and it will not stop until I reboot.. What could that be also bottom of computer very hot?

When my iBook got hot like that, I would take a break and let it cool down.
You can buy laptop desks that have USB powered fans on them, such as the Targus Chill Mat.

Computer Shuts down when on battery power at 80%

The battery power indicates anywhere from 80% to 90% and will shut down the computer.
No warning, No Low Battery indicator, No error messages.
The only way to boot up is to use the power adapter.
I have tried to reset the computer
I have tried to update the latest battery update, but it tells me it is already installed.
This computer is 8 months old.
Is there anything else I can try?

I had/have this exact same problem after I installed the battery update 1.3 on Macbook Pro a few days ago.
I tried a SMC reset & a PRAM reset, all to no avail.
I called Apple today & talked with 2 different agents explaining my problem. One askked me to do another PRAM reset, which I did, again, to no success.
So, they are sending me a new battery, which I am really hoping will solve my problem (Macbook Pro shutting down instantly on an almost full battery at around 84% while not attached to the power cord).
Thing is, I never had a problem with the battery before I installed this update, so this battery update 1.3 somehow corrupted my battery/settings, and unfortunetly once you run this update, your stuck.
There is no way to undo this update as it changes the firmware permanetly.
Ugh.
Next time, I am not going to be so quick when installing "updates", I apparently really don't need. This battery update 1.3 has just caused me headaches & problems on my new Macbook pro.
Heed my advice. Research firmware updates carefully before subjecting your computer to these unneeded "fixes".
My advice is to call Apple & let them know of this problem. Get a new battery. They were apparently unware of this problem update when I called today, and more people need to be vocal about this & complain about this apparently corrupt battery update.
Good Luck.
