Re: m7318 batery

Don't waste your time replacing (only) the bad cells in a laptop battery. The older ("good") ones will be weaker, and will expire next.. quickly, and likely damage the new ones.

All cells must be replaced NEW with equal/same milliamp ratings.

That is true, and useful in SOME laptops, but unfortunately, NOT yours!

Apple uses a small logic circuit in its batteries that "remembers" when it was made, how long it has been used, and when it "died". And even with new cells, this circuit will prevent the iBook from "recognizing" the battery.

Sorry to bear bad news. Dispose of the battery in a safe place (not an incinerator)

My old g4 powerbook is dead, power supply seems to be alright , all battery lights come on on the back but nothing from pressing the power button, no noises , black screen....

HI Nick, I had a similar problem with my Titanium G4 Powerbook in the past. The batterry lights showed OK, and at first glance the original Apple transparent saucer shaped power adapter seemed to be working. But then I realized that the very thin conducter wires were broken where the flexible wire meets the connector plug. I cut into the plastic insulation and soldered the wires-a very tedious exercise I might add. This worked for a few weeks, and as I was at sea on a ship, it kept me going. But before long the same problem occurred-an apparent dead computer. I solved the problem by purchasing a 65 watt power adapter from PowerbookMedic. It was dirt cheap and I haven't had a single hiccup since, and that was 3 years ago. You can always see a Genius at an Apple store, if there is one close to your home. These people are amazingly helpful.

Your cmos battery is dead. The message won't go away until you replace it.

Here's a link on how.

Cheapest place to get a replacement one is ebay ;) otherwise they're pretty expensive :(

Turn on my powerbook G4 but there isn't a chime and nothing comes on the lcd screen

If there's no chime, your problem could be anything from a dead battery or bad AC adapter to a dead logic board.
Does the tip of the adapter on your AC connector light up? If not, that's a problem.
When you push the button on the battery, do you get at least two glowing LCDs? If not, that's a problem.
Otherwise, try the following: remove the battery and the AC jack to make sure the machine is off. Now insert the AC jack, and reset the power management unit by pressing the following multi-key combination:
Shift Control Option Power-button
Wait five seconds, then press the power button to attempt to start the computer normally.
The instructions above are for the 1.5GHz PowerBook G4; the instructions MAY be different if that is not your model.

My computer would not charge. I have an appple powerbook g4. I bought a new battery. I put the battery in. It charges. Now the computr tries to turn on it makes the start up noises but the screen is blank....

Hi, sorry to hear you are having problems,
Are you saying that your Mac was working fine with the dead battery but then when you put in the new battery, the Mac died?
Well, if that is the case it might be possible that the battery ran down to ZERO and the mac's internal battery also is dead so, it does not even know what hard drive to boot into...
So, with the Mac Shut Down, hit the power on button and then VERY QUICKLY, press the ( alt ) key and hold it until you see a blue screen with a Big right pointing blue arrow and a circular arrow.
You can let go of the key, and the mac is now looking for suitable startup volumes to boot from...
You should see your harddive appear after a minute or so... If it does not appear, then either your system is damaged or your disk is KAPUT...
How old is your Mac? It is very very common for PowerBook drives to die after 4 years without advanced warning... :(
Good luck
