my one year old 1.67 pb g4 has "killed" two batteries already. they work for a moment (a day) and then they die (they won't charge anymore, dead). the power adapter has been changed twice as well and nothing seems to solve the problem. has anyone had the same or similar problem? i would really appreciate any insight on the subject.
thanks in advance

Help! My Powerbook G4 came with a broken battery. It wouldn't charge. Apple sent me a new one right away, and after a calibration, my computer would run for four hours while running just one or two programs, including airport, off the battery. Now, my computer is down to 1.5 hours, maybe, and makes a weird humming noise. I've gotten a replacement battery, calibrated it, and I'm having the same problem. When I run Capacity Meter off the battery, it tells me the Amperage is in the trillion+ range. I sense something is wrong but I'm not sure what.

This is driving me batty!

Has anyone configuered a dual monitor output from a PowerBook G4?

I have two old but nice Mitsubishi Diamond Pro monitors. I have been using one for Final Cut edting and would like more layout space.

I am thinking I can use my serial multi-pin port, but waht cable do I need to get?

Forgot to add - once you know that your battery is not as healthy as it should be (e.g. using Capacity Meter). Buying a new battery is the only solution. But look after it from then on.

For those who are wondering why their batteries are no longer holding at least 2-3 hours battery life. Please note the following. (1) Battery life will degrade in any case. So older batteries - 2-3 years old will not perform as well as new; (2) Using the wrong charger (e.g. until recently, Apple used to have different chargers for different laptop models) will damage your battery irreversably. This happened to me; (3) Once un-plugged, try to use the battery till it is fully flat before plugging the power supply back - keep saving your work of course; (4) Go to http://www.macupdate.com/ to download 'Capacity Meter' (free) to check what percentage of your battery is healthy and chargeable.

A simple solution might be that the "power wire" --
the one that charges the battery and provides power to
the computer -- has become dislodged. This happened to
me after months of "intermitent" charging and not
charging. If you are brave, unscrew the bottom plate
and see if the yellow sire is firmly attached to the
wiring harness near where the battery hooks in.

After a few months of being stored (with battery installed), I tried to start my 500mhz G4 PowerBook. Nothing (with and without the battery in). The plug shows yellow not green. Tried zapping pram, push in button under flip down cover, etc. Had the powercord in overnight. Still nothing. Battery lights do not show.
Did my PowerBook get lonely and pass away?

I bought a powerbook G4 12" for Christmas this year and have noticed that the battery will be fully charged and when I unplug it, it goes down to 50% as soon as I use it. However, for many of you, I thought you might want to know that Mac is recalling batteries in models from Oct. 2004-May 2005 so you might be able to get a new battery. It still might not solve your battery life problems.

Yep...I've got G4 battery problems, too. My laptop is over 2 years old, so maybe the battery has just gone bad. Computer geek where I work said it's because I never it let it discharge completely before connecting the power unit. I teach and cannot afford to have my laptop run out of battery. Am currently trying to repeatedly deep discharge (a lot) and this seems to have worked a little. Will probably cough up the $140 and get a new battery.
