IBook won't run on battery. Battery IS fully charged.

AC power supply works fine. Battery charges fine (runs another iBook). When powered down if iBook is unplugged the white power indicator light near the front release latch flickers quickly as do the caps lock and num lock lights.
Tried resetting PRAM and PMU. Apple store says it might be the logic board and I can leave it with them and pay a flat $300 to fix. Wanted to put this out there to the community before I send it away. Any other ideas?

jjj,
Venturing inside the hermetically sealed iBook case, eh?
Well I've done that a lot. Probably close to 50 now.
Let me know what you find.
Well took it all apart. Disconnected everything connected to the logic board. (learned that from a Mac tech) Especially the keyboard and track pad since I know that runs through the PMU. You might try that.
But no joy at all. I'm going to try to inspect the PMU and if that doesn't work I'll probably try replacing the PMU. That could take some time but then this is a donated 1.42.
I tried getting into my iBook once to retrieve a broken off headset jack and was amazed how user inaccessible those cases are.
Yup they're pretty bad.
Email if you want to do that again. I've got some things around here that can help.
(Although I did install a new drive in a Macbook Pro once... I deserve a merit badge for that.)
I just worked on two of these and I thought they were pretty to work on. Love the way they're made.
Doing that on a MacBook is dead easy.
I hear the Unibodies are also nice to work on.

IBook won't run on battery

Hi Folks
Wondering if someone can point me in the right direction here. I have an iBook G3 900 mhz model that I just replace the logic board in (video issue). The ibook runs great now, but all of a sudden it won't work with out the power adapter plugged in. I thought maybe the battery went bad, but I checked it in my other iBook and it is fine.
I bought the Logic board at a discount because it had a missing plug in connector, which is the one that connects from the Logic board to the power button. I soldered it back on and powered up the Laptop fine. and it even worked with just the battery for a short while, but now only works with the adapter. Should I open it up and re solder the connection, or is this another issue?
Thanks
Don

Hey Don,
I have an iBook G3 900 mhz model that I just replace the logic board in (video issue).
Just curious. Did the GPU chip die? or was it the BGA issue? I repair and donate iBooks to inner city school teachers.
it had a missing plug in connector, which is the one that connects from the Logic board to the power button. I soldered it back on and powered up the Laptop fine.
Wow good job! That's not easy to do. BTW that plug would have nothing to do with the not running on battery problem. It's part of the "soft start" circuit.
This is from the service manual for the 900:
"The computer runs when plugged into a wall outlet but not on battery power
1. Reseat battery to verify battery is seated correctly with battery lock engaged.
2. Try known-good charged battery.
3. Reset the power manager by pressing the key combination Control-Option-Shiftpower.
Warning: Make sure you do not hold down the "fn" key when resetting the
power manager.
Warning: Resetting the power manager will permanently remove a RAM disk, if
present, and all of its contents. You will also need to reset the date and time
(using the Date & Time control panel).
4. Replace logic board."
That "power manager" they speak of is a PMU 99 which I believe is CMOS and very sensitive to static charges.

Dv7 Laptop won't run on battery

Laptop Data&colon;
[Image Removed]
Upon unplugging my laptop last night, it simply shut off, and since won't run off of the battery. It seems like the battery isn't connecting to the motherboard, but I ran a test in the support assistant that gives me this:
[Image Removed]
Is one of the cells dead, and that is why it isn't working, or could it still be failure to connect to the motherboard?
I have another battery, but unfortunately not currently with me.
The battery also won't charge past 86%, but again, I'm unsure of the cause. I left it out overnight and long held the power this morning to no avail as well.
Any help is appriciated. Thanks.

I understand your notebook battery no longer powers the notebook and the battery test has failed.
Reviewing the battery test, it looks like the battery (when fully charged) is only holding about 35% of the original charge. This means that the battery life wont' last very long as it will drain much faster. This is the most likely reason that the battery is no longer functioning is that it has reached the end of its usage. The battery test requires the battery to interface with the motherboard for it to test the battery, so I don't find the motherboard very likely at this point since the test was able to detect the battery.
You stated you have another battery to try. Try using that battery at your convenience to see if it can power up the notebook before purchasing a new battery. Should you proceed with a new battery, the replacement part number should be listed on the current battery.
Let me know if this answered your question.

IBook does not run on battery

My Ibook does not run on battery when it reaches 48%. It just shutsdown with no warnings. I have to connect the AC adapter to work if i disconnect it the ibook just shuts down. I have to waut until it reaches 100% and then i take the AC adapter. I book shuts down and after i turn it on with out the AC and it stays running on bat until the 48%. Then i have to go through everything again.

Till now my battery has been working perfectly. The machine is about 1 year old and I use it heavily for my work. I prefer to unplug my battery when it's full, and use it till it go's to sleep before plugging it in again. This results in a very high Cycle count (453) but a still perfectly working battery (98% according to CoconutBattery), I can use the machine for about 4 hours on a full battery.
The amperage would be 0 since your battery is not in a charge cycle.
Part of your problem could honestly be your cycle count and method of caring for your battery. If you check some of the research about Li_ion batteries this is the worse way to use it. Li-Ion batteries work best with little charges. Deep cycling Li-Ion can kill the cells. There is no good reason to charge the battery and then use it as you have been doing. This just kills your battery for no reason. The MacBook is designed to cut the charge off when the battery is full and it does not hurt the battery to lie idle like this. The method you're using can prematurely kill your battery.
Either the battery has a problem that is not showing on you readings or the battery circuit is fried. Do you know someone that has a MacBook or live near an Apple store so you can test your battery on a known good MacBook. Or you could try one of their batteries in it.

PB 1400cs won't run on battery power

I've got a 1400cs, purchased second-hand, and it seems to have a problem running on batteries. Even with a new battery, it doesn't want to run on battery power. `Runs fine on AC power, though!
What could cause this? What are my options for inexpensive repair on this problem?

Keith,
I also have a 1400 with the original battery which will not even run the 'book for a second when I unplug the power adapter, but I don't use the 'book anymore. Surprisingly, the battery level gauge in the menu bar is all red and the Control Strip shows a fully charged battery.
In the menu bar, at least with the OS 8.6 I am running, the red vertical bar or cylinder is a capacity gauge; when all red, the battery is full; as power is consumed, the red starts dropping down and the top is filling with blue. Your gauge indicates a fully charged battery.
The only time you see the lightning bolt is when the battery is charging and you will see it in the menu bar and the Control Strip.
You know the power adapter is connected by the presence of the plug in the Control Strip.
The bars in the Control Strip are all gray when the battery is fully charged and all white when empty.
Remove all power and take a look in the battery bay with a flashlight; gently touch each pin with the eraser-end of a pencil and see if any of the pins is loose or possibly set back beyond the others.
According to Apple service guides, if you have performed the resets and have a known-good battery and power adapter, the only fix is a logic board.
Do you have a 45w power adapter and have you tried another power adapter? You can use the PB1400 or 3400 or any G3 or clamshell iBook adapters.

Battery stopped charging; won't run from battery

A couple of days ago, my computer stopped running from battery, and stopped charging the battery. I can see that the level is 67%, but that never goes up, and it shuts down if I unplug the power adapter.
Here is XBattery info:

Anyone know how I can fix this?

I have the same issue with my Powerbook G4 15" Aluminum (battery not charging and clock not retaining date and time). A 3rd party warranty company is trying to say it's the rechargable battery but I think it's something to do wit hthe small battery located on a daughter board on the motherboard. Can anyone verify this or does this sound like a totally different issue?
The battery was replaced under the recall less than a year ago.
Thanks,
Bob

Mac book pro won't turn on and battery is fully charged..

My Mac book won't turn on... The battery is fully charged, we have it hooked up to power... We've tried holding power button down and disconnecting from power but nothin have worked! It makes a noise like its going to turn on and little white light flashes but nothing happens

Try a safe boot, see if it starts, this takes a bit longer. Push power button while holding shift key, continue to hold key till you see the progress bar. If it boots, shut down and try to boot in the normal way. Best

I left my 4s in the car for apprx 35 mins in 35 degree weather and the phone completely shut off and won't turn back on. the battery was fully charged

It probably overheated and shut down. Hold the HOME and SLEEP buttons until an Apple logo appears. This will take 10 to 15 seconds of holding both buttons.

My battery is fully charged, but when i disconnect from mains MBP won't start

As soon as i remove mains cable from MBP the laptop just crashes ... no juice ... even though it says battery is fully charged. As soon as i replace cable, it reboots ... i need this laptop to work on battery !!

Try resetting the SMC. If that doesn't work, I would get the machine to Apple for service ASAP.

My four-month-old macbook pro's battery when fully charged is now down to 2 hours life from 7...in the last week. Why?

I bought my macbook pro 13" about four months ago and have been in love with it ever since - especially as compared to my old PC laptop, the battery stays cool and lasts forever when I am working. Best charge was 7 hours. However, in the last week I have noticed the battery suddenly becoming hot when I unplug the charger, and the best length of time I can get on a full charge is 2 hours.
I have made sure all the settings are for prolonged battery life - which they've been since I first set up - and turned off all programmes running in the background, but this has not made any difference. I have been using iMovie a lot lately which takes a lot of battery which is probably why I didn't notice the battery being low as it automatically seems to make the battery slump to 2 hours when it's on. It's off now, and my battery won't improve.
I have also now followed the instructions (below) about calibrating, but this has had no effect. My housemate bought the same model a month ahead of me, uses it probably slightly less, but his is still 7 hours for a charge.
Is my battery faulty?
Calibration instructions used:
PowerBook G4 (15-inchDouble-Layer SD), MacBook (all models), MacBook Pro (all models), and MacBookPro (17-inch) (all models)
Thebattery calibration for the PowerBook G4 (15-inch Double-Layer SD) and anymodel of MacBook or MacBook Pro has been updated because of a new batteryreleased with this computer. With these computers, follow these steps tocalibrate your battery:
Plug in the power adapter and     fully charge your PowerBook's battery until the light ring or LED on the     power adapter plug changes to green and the onscreen meter in the menu bar     indicates that the battery is fully charged.
Allow the battery to rest in the     fully charged state for at least two hours. You may use your computer     during this time as long as the adapter is plugged in.
Disconnect the power adapter while     the computer still on and start running the computer off battery power.     You may use your computer during this time. When your battery gets low,     the low battery warning dialog appears on the screen.
At this point, save your     work. Continue to use your computer; when the battery gets very low,     the computer will automatically go to sleep.
Turn off the computer or allow it     to sleep for five hours or more.
Connect the power adapter and     leave it connected until the battery is fully charged again.
Tip:When the battery reaches "empty", the computer is forced into sleepmode. The battery actually keeps back a reserve beyond "empty", tomaintain the computer in sleep for a period of time. Once the battery is trulyexhausted, the computer is forced to shut down. At this point, with the safesleep function introduced in the PowerBook G4 (15-inch Double-Layer SD)computers, the computer's memory contents have been saved to the hard drive.When power is restored, the computer returns itself to its pre-sleep stateusing the safe sleep image on the hard drive.

When my battery is fully charged it says only 5-6 hours left should it no be 7?

i got my macbook pro a few days a go and when my battery was fully charged it says ther is only 5-6 hours left , is there a problem with my battery

For starters, your battery will need to go through a few charge cycles before it reaches its full capacity. That aside, most people won't hit 7 hours in normal use. Apple (indeed, most computer manufacturers) tend to do their battery testing on very conservative settings (somewhat less than most people will use) so their reported battery run times are a "best case" scenario... not an average.
The time remaining indicator is also only an estimate based on your current usage. Your battery has hardware internally that reports the actual percentage of your charge remaining. Your computer than "estimates" how much longer the charge will last. It works sort of like burning gas in a car. The more processor intensive the task (i.e. pushing the gas pedal further), the shorter your charge will last (i.e. the faster you'll burn through your gas).
So, if your computer is just sitting there and you have absolutely nothing running and you have the display backlight turned way down, you may get an estimate of five or six hours... but if you start to watch a flash video or perform some processor intensive task, the estimated time remaining can change so something like three hours almost instantly. It's basically calculating your remaining time on how you're using your computer "now" and that estimate will always update in real time based on your use.
If you want to get a better idea of how your battery is discharging, you can click on the battery icon and have the display show the percentage remaining vs. the time remaining. When you display the percentage, you will get the actual percentage which will not fluctuate like the time remaining may.
