Dead battery? "No battery found" etc.

Message #1 - Posted 2005/01/02 - dylanpank

Hi there, I have a query and just wondered if anyhone else had a similar problem, and suggests a solution. Some water got spilt on my ibook last night and since then the battery has been acting weird. Basically when I start it up it's there, but with no charge, all I get is ""calculating until full" and 0% charge. If I unplug the cable then the computer immediately goes to sleep.

After a certain amount of time (usually minutes) the lightning bolt in the menu bar battery is replaced by an X, with the message "no battery found". If I unplug the computer at this point it shuts down and has to be plugged in again and restarted.

Also, taking out and putting back the battery also seems to help the battery be found again, but only in the condition described in the first paragraph.

Is the fault with my computer or the battery? is there something I can do to fix it or is it only a job for a professional? I've zapped the PRAM and it's m,ade no difference as far as I can tell. Thanks in advance

You don't say where the water went but I assume you mean that enough water was spilled that it flowed into the computer to unknown locations. The first thing that you must do is dry the water out. Remove the battery and keyboard and let warm dry air blow over it for a long time (hours) and try it every so often to see if it works. You may want to try resetting the PMU also.
1. If the computer is on, turn it off.
2. Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes. 3. Wait 5 seconds.
4. Press the Power button to restart the iBook computer.

Some might say to NOT run it until the water is out. Well, you have already run it so it is unlikely the water will do more damage than it already has, if any, from this point onward.

I agree with another poster who suggested you give the iBook more time to dry.

You can try resetting the PMU. Go to the Apple support area and put "reset PMU" in the search box and the appropriate article will appear near the top of the list. Not all iBooks use the same PMU reset method so check which one is right for you.

If, in the end, you end up with the situation you have now, you might see if, during the short period the system can see the battery, you can recalibrate it.

Thanks to both of you, Indeed we did give the ibook some time to "dry" before gingerly switching it on this morning. Pailfac, you're right I'm not sure exactly where the water went as it splashed across it, but it wasn't exactly drenched, though some did get into the grill at the back (where the hinge of the screen is) which suggests it splashed from behind (it was closed at the time luckily).

So far it seems fine apart from this battery issue, so to be fair on the one who actually spilt the water it may not actually be the cuase of this issue, seeing as the battery was away from where the water seems to have gone.

I'll give ther PMU thing a go. Once again thanks for the quick responses.
