1.67GHz G4 15-inch Battery

Just opened 2 brand new powerbooks and neither of them will charge. The reading is at 0% and the light is green.
tried resetting the power management unit. No change.
ANything else I could try/do?
Thanks in advance.

It's possible that the internal battery is dead. Often just leaving them plugged in for a long period helps get them started. First try for an hour then if that fails try for six, over night would be simplest.

  • Can i find macbook air 11 inch battery life 7 hours ?

    hello apple
    can i find macbook air 11 inch battery life 7 hours ?
    thanks

    Well, the battery life for an 11 inch MacBook Air is 5 hours.  The 13 inch Air has a 7 hour life.
    Here's the specification:

  • MacBook Pro Retina 15-inch battery life on Yosemite

    Has anyone noticed impact on the battery after upgrading to Yosemite? I found only one article online that talks about the impact. I followed the instructions but still the battery life did not improve. I'm running MacBook Pro Retina Late 2013, 15-inch, 2.6GHz Core i-7, 16GB RAM.
    I think that I should be getting more than 8h of life when fully charged.
    Link to article on iMore.com: http://www.imore.com/how-resolve-battery-life-troubles-your-retina-macbook-pro

    So here is an update: I've followed the article posted by OGELTHORPE (Thank you!). What I actually did is 1. Reset the SMC and 2. Reset the PRAM (MacBook Air SMC and PRAM reset).
    What I've seen so far: Once I did the reset, I would guess that the system needed to re-calcualte again the battery charge. Initially after I disconnected from power, it started with a measurement from under 3:30h. After 45 minutes running on battery it is showing again 8:45h remaining  @ 93% charge. What I noticed is that every time I put the laptop to sleep this repeats - starting with some low time measurement and slowly climbing. I think that this could be a bug in the software and the battery charge calculation method is somehow not working properly. I wonder after those resets if the OS needs to get into a couple of battery charge cycles and the battery is calibrated again?
    I don't recall having this issue with the last year's release of Mavericks.
    I hope someone from Apple sees this and address this with the next OS X update.

  • Macbook pro (13-inch) battery life?

    Hello,
    I've bought a Macbook Pro (13-inch, mid 2012, non-retina, OSX Yosemite 10.10, i7 processor) 3 weeks ago and I was wondering how long the battery usually lasts and what I can do to increase battery life.
    Currently it only lasts up to 5 hours, despite it promising 9 hours of battery life. This is mostly while using Google Chrome and iTunes. It feels like I'm recharging it constantly and it already has been through 23 battery cycles - at this rate my battery would only last 3 years which would be shorter than my previous laptop did and I expect more from something that cost twice as much as my previous one.
    So am I doing something wrong? Is there something broken or is max 5 hours of battery life normal?
    With my previous laptop I also used to take out the battery and use only the adaptor to save my battery, but as I can't remove the battery of this laptop I was wondering if leaving the adaptor in while working at home so it remains at 100% would be a good idea or would that actually be worse?
    Many thanks in advance!

    The battery life is stated as "up to" 9 hours, not promising 9 hours. Having said that, I would suggest using a browser other than Chrome, as it is often considered a battery hog. Also note, it is perfectly fine to use the computer with the AC power connected. As a rule of thumb, use it AC power when available, and on battery power when portability is required.

  • IBook G4 14 inch battery

    My 15 month old iBook G4 14 inch's battery is messed up. It keeps going down and now i only charge it for 45 mins and its fully charged and i can use it for only 1 hour or 45 mins

  • New MacBook Air 11 inch Battery Problems

    I just got my new mac book air home and ran a full charge into the battery.  Once i disconnected it from the power adapter i noticed the battery was still only showing around 4 hours of life.  Nothing was running on the matchine at the time, other than a wifi connection.
    As I started to use the machine (writing an email in a single browser window) the batter indicator began to jump in a seemingly iratic way.  After 30 mins of use, the batter indicator was showing less than 2 1/2 hours life remaining.
    I've run the latest software updates and the same issue persists.  My machine is an 11 inch 1.6GHz model running the i5 processor.  I can see a few people have had issues in the past with eratic battery indicator behaviour but cant see any difinitive solution?

    There is no definitive solution.  The time remaining indicator provides an estimate only based on the current load on your system.  When you first start using it, there will be more activity than normal as your system is set up and Spotlight indexes your files.
    Think of your computer as being a car.  If you're going along a flat road, you can keep the gas at a steady level.  At that rate, maybe you can get 100 miles out of the gas you have remaining.  Now, if you suddenly go up a steep hill, you're going to have to use lots more fuel and all of a sudden, you may only get 50 miles out of the gas you have remaining.... but if you get to the top of that hill and then start coasting down, you might be able to get 200 miles out of the gas you have remaining.  How many miles you can get out of the gas you have remaining will always change if you measure it by what your car is doing "now".  However, if you look at the gas gauge instead, it will not fluctuate that way... it will always show you how much gas you have remaining.
    To get the same accurate "gas gauge" reading, you should view your battery by the percentage remaining vs. the time remaining.   The percentage remaining is the "actual" percentage of your charge remaining.  The time remaining is only an estimate based on your current usage and it can fluctuate wildly depending on what your system is doing.

  • New MBP 17-inch battery

    So since the battery is built in on the new 17-inch MBP, does anyone know what happens when the battery is toast and doesn't work anymore, what do you do? Do you have to send it in and get it repaired or can you do it yoursef by just un-screwing screws and getting a new battery?

    Hi, justono, and welcome to Apple Discussions. You take the computer to an authorized Apple service provider and pay them to replace the battery for you. The announced price is $179. The battery is not a user-serviceable part, so a) end users probbly won't be able to buy replacement batteries to install, and b) trying to change the battery yourself would likely void your warranty coverage in some measure, if you did it while the machine was under warranty.

  • Macbook pro mid 2010 13.3 inch - battery charging

    I have a Macbook Pro mid 2010, 13.3 inches.
    The battery stopped charging, I see the problem was the dc MagSafe. Replaced it, now only connects the laptop (I've tried with another battery and the problem persists, my battery works and usually carries another laptop) and work with it plugged in but not charging the battery.
    What should be the problem? Agurado suggestions ... I've tried the SMC, I tried to put another battery, etc etc, and the problem persists.
    I wish I could help.

    Open System Profiler>Power and post this from your MBP:
    (make certain that your charger is connected?
    Also run an Apple Hardware Test:

  • MacBook Pro mid 2010 13 inch battery?

    Hello,
    I remember my old MacBook's (white, early 2008) the battery showed things like : "Replace soon" and so, but on my MacBook Pro it went to Service Battery immediately.
    Now it seems it still holds as much as charge as it did before, so I don't know if I should replace it. First I'll try calibration. I already reset pram and everything… Shouldn't the cycles be up to 1000 at least? This is why I bought this MacBook at first place.
    According to Mac notebooks: Determining battery cycle count it is 1000 cycles, but I've only charged it 420 times.
    What can I do to improve my battery's life and why isn't it 1000 cycles as Apple promised? I have a feeling I will never buy any Apple products again if I have to say goodbye to my battery soon. Disappointment after disappointment ;( Hopefully it can be still saved without a replacement.

    It's quite important to remember that the lawyers added two wiggle words to convert a tech parameter into Legalize (my emphasis in bold italics):
    The built-in battery of your MacBook Pro or MacBook Air is designed to deliver up to 1000 full charge and discharge cycles
    [from http://www.apple.com/batteries/notebooks.html under the section, "Your New Notebook"]
    That means they don't HAVE to replace a battery that signaled "Service battery" but is otherwise not showing signs of failure like leakage or short runtime.
    ToWhite-1: Were it I and I were getting reasonable runtime, I'd be inclined to ignore that warning for the time being and simply watch for sudden changes or a catastrophic drop in runtime.

  • New Macbook Pro (2010) 15 inch battery issues!!!!

    Hi,
    Please help me.I sense a fraud act by the macbook servicing center in my city.
    My macbook was bought in 2010 and after having used many times I was said tha the machine was getting heated up due to poor standard of the battery and that the battery needs to be replaced.So here are my questions in points-
    1.When I get my battery replaced without warranty,Should I get the Old battery or does the servicing center replaces my battery with a new one and does nt return me my battery.
    2.The battery,when i tested through COCONUT BATTERY appliocation shows 89% capacity with 374 cycles,which means its not new.Because in 1 day it cannot be upto 374 cycles.
    3.What should be th ideal battery standby time for a new battery of macbook pro.Currently its showing only 3 hours!!!I think its totally unbelievebale.
    4.Is there any opther application to check the battery isd new or not??????

    Thanks a lot for your info, Glynn. I appreciated much.
    Unfortunately, the Apple dealer said that currently there is no this type of mac in their inventory. Therefore they can not do a complete replacement & they referred me to Apple authorized service center. Today, I got more news from this Apple authorized service center & they suggested to return my new macbook pro to the Apple Dealer where I purchased my Mac. After sent Email to Apple, tomorrow they will contact me. Hopefully they will not referred me again to other place...
    This is like they sent me back and forth and it's really frustrated. This is the worst experience I ever had in buying computer & I am feel that I paid to much for such low quality product & service.
    Sorry Apple, but this is really disappointed me.

  • IBook G4 - 14 Inch Battery Bay

    with your new hard drive, do you get worse battery life? i got my 30 GB replaced with an 80 GB and now I have significantly less battery life... dis this happen to you? (assuming you got a bigger HD)

  • Charging Mac Book Air 11 inch battery

    hi, all
    I have been advised by an Apple retailer and service provider to start recharging my Air's battery when the charge remaining drops to 80%, the rationale being that below 80% means another battery cycle. Is this true? Or would it be better to charge when the charge remaining drops to 40-50%??
    Ken

    That is incorrect. A "cycle" requires a 100% cumulative discharge followed by a 100% cumulative recharge. If you discharge the battery to 50% then recharge it you have complete 1/2 a cycle. You can permit the charge to drop to between 10-20% before recharging. This allows the battery to discharge enough to keep the electrons flowing and will ensure a longer battery life.

  • Replacing a Battery?

    Hello Experts!
    I have the previous generation MacBook Pro (bought in 2007 before the latest generation came out a year ago or so) and I need to replace the battery because my old one has been through about 600 charge cycles and it's definitely being shown the door. So my question is are the batteries for the current generation MBPs and my slightly older MBP the same, so I can just get a new 17-inch battery from the Apple Store and it will work? Or do I need to find a battery specifically for my version of the MBP? I figure Apple would probably be smart enough to have one battery for the entire range, but I remember SJ making a big deal about how long the battery life was on the new MBP so that's got me wondering if there was a change. I'm sure many of you know whether I can buy an off the shelf battery and swap it for my old one, so if that's the case then please help me out so I don't scrub a hundred odd Euros buying something that doesn't work.
    Thanks in advance guys!

    There is only one type of user-replaceable battery for the 17" MBP (there are two types for the 15" MBPs). The batteries on the newer models are not user-replaceable, so you can't just 'get one from the Apple Store.'

  • Strange Battery Malfunction

    Here is my situation...
    Recently my 3 1/2 year old powerbook G4 17 inch battery went out. When I would plug it in the plug adapter light would turn green then orange immediately. If i press the power button (just on quick press) it would turn green, however no noise/slight humming as usually happens when powered up and the screen would remain black. To test if it is on, I press the caps lock button, and it lights up. Still no noise no screen no nothing. press the power button and hold it to shutdown and reboot. The light on the plug turns orange again. press the power button to restart, the light immediately turns green, and same as before no noise, no screen. At this point I remove the battery completely and reinsert, retry the previous steps, same response as though the battery never had been removed. Without the plug inserted the computer has zero juice. So I conclude its the battery.
    Two days ago I go to an apple store and buy a brand spankin new battery. Get home, change batteries and plug it in. Everything works as usual. I let the battery charge over night and it works fine the next day as well. That next day I let it drain all the way down and then charge it back up still working. I put the computer to sleep, put it in my bag and go home from work. Today I get to work take out my computer, and it wont turn on. So I plug it in. NOW IT IS DOING THE EXACT SAME THING AGAIN!!! WITH A BRAND NEW BATTERY!! I understand why my 3 1/2 year old battery wont hold a charge anymore, but why (even if drained completely) would a NEW battery be doing this?!? any help please!

    You might try resetting your power management unit, as per Apple the settings can sometimes become unstable over time: http://docs.info.apple.com/article.html?artnum=14449
    Also, make sure you condition your new battery, per this: http://docs.info.apple.com/article.html?artnum=86284 . While the article says to do the drain/charge cycle once, Lithium batteries typically respond best to doing this 2-3 times.

  • "Battery serial does not validate", but the number is within the range

    My sister came home from abroad for Christmas, and I checked her PB 12-inch battery serial number. Her battery has the serial number ZZ3480FJPVEA as far as I can see. This falls into the replacement range:
    12-inch
    iBook G4 A1061 ZZ338 - ZZ427.
    On the exchange page, Apple writes: "If the first 5 digits of your battery’s 12-digit serial number fall within the noted ranges, please order a replacement battery immediately." But the battery serial does not validate even if I replace the zero with the letter "O".
    Are there batteries within the range that still are ok?
