PowerPC :: Powerbook G4 Power Options - Battery Is Showing Full Charge?

Sep 7, 2007

I have a 1.67 GHz Powerbook G4. This morning it was fine. When I got home from work, it decided that it suddenly no longer wants to stay on when not plugged in. The battery is showing a full charge. The light on the plug is green. But the second I unplug the cord from the laptop, the entire thing shuts down.

PowerPC :: PB G4 1.67 - 15" Battery Power - Green Light Never Came On To Indicate Full Charge

Sep 17, 2010

Basically I'm having issues with my newly acquired Powerbook G4. When i bought it the battery was not working at all so have now installed a new replacememnnt battery which works fine but having some slight issues. So...

First time I charged it, it reached 100% but green light never came on to indicate full charge. When I run the PB off the battery it gets to 20% and it shuts down without any warning it's low on battery (trying to switch it on after this is impossible, it clearly has no life) After the above I connect the power lead and start up the computer, the battery indicator starts charging from 20% onwards. Something fishy definitely going on and I have no idea what it could be, I calibrated the battery but it has always cut off at 20% since first charge/discharge.

MacBook Pro :: Battery Showing Full Charge But Stays Constant At 98 Percent?

May 3, 2012

Why is my Mac not at 100% battery after having it powered off and plugged in charging all night? As long as my charger is plugged in shouldn't it be at 100%? I never unplug it. It shows it is charging but stays at a constant 98%.

PowerPC :: Battery Doesn't Charge On Powerbook G4?

Oct 26, 2010

Some days ago i finally added a Powerbook g4 to my Mac collection and since then ive been trying to fix this computer without any results. The Powerbook had the battery dead at first and i had to replace it with a new one i had. Now the problem/weird thing is that the computer detects the battery but it doesnt charge. It has about 18% of the charge and when i try to boot up all i hear is like a fan sound and nothing more, no boot up sound and no image on the screen.

If i boot up using the power cable thats when i see the 18% of the battery icon, but as soon as i take out the power cord, the image goes black although the computer still makes sounds as if it was on. Does it have any solution? PS: ive tried to reset the PMU,changed the pRam for a new one, reset the Nvram.

PowerPC :: Battery Not Showing Correct Charge?

Aug 3, 2007

I have a 1.33Ghz 12" powerbook and recently it has started to just shut off when the battery is saying it has around a half hour left, instead of it warning me that the battery is low and it will go to sleep soon. and then it won't restart until I plug it in. is there any way for me to fix this besides getting a new battery? This battery is not covered under any recalls, and there is no applecare left on the computer. also if it matters the computer is running 10.4.10.

PowerPC :: Powerbook G4 Won't Power Up - Battery Indicator Showed One Flickering Power Circle?

Mar 19, 2008

My girlfriend has a 12 inch Powerbook G4. She noticed that the battery life was starting to dwindle. Tonight, she tried using it. It wouldn't power up. The battery indicator showed one flickering power circle. The adaptor has the green circle on it, indicating the battery has a full charge. However, the computer won't charge up.I've read the 12 inchers don't have separate PMUs. Could that prevent the machine from starting? She was using it earlier this evening, as she e-mailed me pictures from our vacation.

Power PC :: Mac PowerBook Won't Charge / Get It To Work?

Oct 18, 2009

Having an issue charging my mac. When I plug the charger into my mac, it turns orange, so I know its charging, but no matter how long I leave it in for it never has enough power to turn on.

If I move the charger around slightly at an angel in the hole it turns green and only then will it turn on, but the moment the green light goes back to orange the laptop turns off.

When I do manage to get it turned on, it says there is 0% battery.

I've tried using different chargers so could the problem be with the connector in the laptop?

MacBook Pro :: Full Charge Capacity Of New Mbp Battery?

May 23, 2010

I received my new 15", i7, 128gb ssd, 8gb ram macbook pro on april 19th. I love it and have no problems. Have any of you guys noticed that the full charge battery capacity, which is found under system profiler-power, varies often. When I first got the macbook pro the full charge capacity of the battery was around 6830. Now with each charge it seems to go down slowly. At first it jumped from 6800 to 6600 and now stays at around 6520. Is this normal?

MacBook Pro :: Battery Time - Getting 2 Hours With Full Charge

Jun 27, 2009

Late 2008 refurb Macbook Pro, 2.53ghz, Windows 7 RC (therefore forced to use the 9600 at all times). According to this report, the MBP got around 3&1/2hrs of run time with a dimmed screen and watching videos. From a full charge, I start browsing the internet (no videos at all), and my battery reading read as follows

91% 1hr, 16mins
90% 1hr, 20mins
89% 1hr, 24mins
87% 1hr, 23mins

Not only were the readings all over the place, but even from a full near charge I wasn't even getting an estimate of 2hrs, while Apple advertised 4 for the late 2008 model, and the review I linked to says they got 3&1/2. Do I have a bad battery, or does simply running the 9600 reduce the battery life by such a drastic amount? I have already calibrated my battery following the guide on the Apple website.

MacBook :: 2.1 Won't Hold Charge But Battery Indicator Is Full

Jun 7, 2012

My wife's Macbook 2.1 is acting strangely. The Battery indicator led's are full (green) the charger led is also green and the software shows 100% battery is charged. After a couple of seconds after disconnecting the charger it switches off. I've tried resetting the SMC and this allowed a full nights use without the charger but on the next day it went back to only holding for a couple of seconds. I don't want to have to reset the SMC every day. It's running on 10.5.8 and is all up to date.

MacBook Pro :: Unable To Charge Full Battery / Charging Stops At 70%

Dec 19, 2010

Then I can reboot work for half an hour until battery is like 50% then it shuts off again... then I can reboot again and work for some more time. I've checked with coconut battery and when the computer stops at 70% I still have like 1700 mAh...I've reset PRAM, power management, etc...

Of course my battery is old, but it should work until 00%... not stop at 70%. Before I spend like 100$ (that is what a macbook pro battery costs here in Mexico) I'm willing to try anything...

PowerPC :: Powerbook Battery - Significance Of Levels For Powerbook G4 15''

Nov 15, 2006

I am leaving for a week long trip and many parts of it will not be able to run the computer off of the powercord, which is a problem because I get about 40mins of wordprocessing use out of it when I run the battery alone. Can someone explain what the significance of these levels are for my Powerbook G4 15'' (Alm) 1.25GHz, namely the cycle count and full charge/remaining capacity?

PowerPC :: My Powerbook No Longer Draws A Charge From The Mains?

Feb 7, 2007

My 1.67ghz, 15" high resolution, Powerbook seems to be broken. I use my laptop all day every day on battery power, and charge it through the night. Today, when I got home, it drew no charge from the adaptor. I have a backup iBook G3 which still charges perfectly off the same adapter, yet the Powerbook doesn't. I have left plugged in for about 45 minutes now, but still no charge, so the computer won't start up. I have a lot of important work on this computer, so I at least need some way of getting my data off it without ripping it apart to remove the HD. What should I do? I suspect that the power port in the laptop is somehow deformed, and thus is not making a connection. If this is the poblem, will it mean a new logic board?

PowerPC :: Powerbook Light Options?

Aug 10, 2009

My powerbook G4 has a button thats used to unhinge the LCD screen and flip the computer open. When I flip it open, the light turns on, but it should be off. If I pull the LCD screen forward as if I am going to close the screen, the light turns off as I am pulling the screen forward. As soon as I stop the motion, the power light goes back on. Its very odd.

OS X :: MacBook Battery Not Charge / Power Light Stays Green

Sep 25, 2009

I have a 2008 Macbook and when the power is plugged in, the light is green, however my battery will not charge, and it even says at the top "battery is not charging" If I remove the power cord from the computer it will still run off the remaining % of the battery, but If I reconnect the cord it lights up green and I never see the amber charging color. I traded out my battery as well as a different cord and still the same results. My battery will charge up on a friends macbook, but not on my own. I want to take it to the apple store but I'm at school and there is no store near me.

Mar 14, 2007

My iBook G3 800 MHz will not charge any more all of a sudden. I have tried plugging it in to several power sockets and it won't charge. Whats more... I tried charging it with just the normal charger, and I even tried charing it with the extension wire! I am not sure if it is the charger, or my iBook. If it is the iBook, should i rip it open and get a new part for it? If it is the charger, where can i get a new one?
