MACBOOK WON'T RUN OFF BATTERY

My MacBook will not run off the battery.
I replaced the battery. Now when the machine boots the battery icon indicates that it is calculating for a few minutes and then displays an X in the icon.
I click on the icon at get the message that NO BATTERIES AVAILABLE.
The battery is charged and I have reset the SMC.
From all of the disussion groups this appears to be a common problem.
IS THERE A SOLUTION?

Hello leighdk,
Welcome to Apple Discussions!
You can by all means take some good advise from the people on this board in response to you problem.
But here is the best advise, especially since you're new to Mac.
Call Apple Care or take it back to the store and have them check it out. It is under warranty. You have 14 days from the date of purchase to return the Mac for a completely different or give it back because you do not like it. they may try to charge you a restocking fee but this should not be the case since there is an issue with you machine.
Call Apple, see what they say... Then if you can't get it resolved then post back and maybe we can give you some sound advise.

Brand new macbook won't run off battery, only when plugged in

I just go my new macbook last week and being new to mac computers, I didn't realize that it won't run from just the battery power until last night. The battery light shows it's fully charged. If i'm working with it plugged in and it becomes unplugged, it shuts down and when I reconnect the power cord, it resumes from the same webpage or whatever I was last working on. I opened up the battery compartment and removed the battery and then held the power button for 5 seconds, but that didn't fix the problem. Does anyone know what I might try or if something needs to be set up in order to run off the battery? Thanks! Leigh

Macbook won't run off charged battery

My battery indicators on screen and underneath the Macbook show maximum charge but when I remove the power adaptor, it dies.
This started to happen a few days ago after a couple of years with zero problems. I tried re-setting the SMC but it makes no difference. As the battery is charged, it seems unlikely just changing it will help.
Any ideas please?
The spec is.

MacBook won't run off of the battery

My daughter's MacBook is a couple years old. Everytime she tries to use the computer without it hooked to the AC source, it will shut down when the battery reaches 94% battery power. I've reset the SMC with no results. She then hooks the computer to the AC power. It will show an orange dot on the cable. The battery charges to 100%, the dot turns green. She disconnects the AC source. The battery gets to 94%. The computer shuts down.
Here is the information regarding the battery. This information was taken right after a shutdown.

I did notice that after studying this information before the shutdown the cycle count never changes. Also the Full charge capacity when the battery read 100% was in the 6,000 range. Don't know if tht makes any difference. Any help would greatly be appreciated!!!
Thanks!

Sounds like the battery is bad. Replace the battery.

MBP won't run on battery

As of a couple days ago, my MacBook Pro won't run off its battery. When I press the button, all the battery lights light up, indicating a full charge. But the computer won't turn on. Only when I plug in the power adapter does it work. If I pull out the adapter when the computer is on, it shuts off.
Yesterday, I noticed something peculiar. The light in front, which normally pulses when the computer is in sleep mode, was sort of half-pulsing. It would slowly fade on, then immediately flick off. Not sure if this is an indication of anything.
Is this definitely a hardware problem? I have an appointment to see a Genius tomorrow, but I'm wondering if there's something I can do on my own first.
Thanks.

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.

I'm having similar issue after upgrade to 10.4.10. My mbp is practically new, only a few weeks old. Originally thought it was Safari and flash problem but it also happens in Firefox. Went to genius bar, in log they saw problem with airport. they said it was problem at my home wireless since computer seemed to work ok in store, though we did not have it connected to internet very long in the store and store is open net, not closed.
when i got home and started browsing, my computer crashed twice, in both Safari and Firefox. It would have connection for a few minutes and then crash. (screen slowly turning gray and then prompt to restart). I ran internet connect diagnostic and it said i was not connected even though i had strong signal on icon. i could see internet connect icon in dock switching from ethernet to wireless (no ethernet cable connected). I did the diagnostic wizard thing and got a prompt that my WEP was not in the keychain and if i would always allow it to connect for diagnostic. I entered always and entered wep for keychain. I have not had a crash since but admittedly I have not had time to really put it to a test. Also, I have been helping it along by launching internet connect along with whatever browser in an effort to wake up both the airport card and the wireless router. I don't think you should have to launch internet connect to start or keep a connection going, but it seems to be working for me so far.
I'm open to more suggestions myself since i'm not so sure the issue is solved yet.

My MBP has been running like a champ since I bought it in March. However, I started having the same exact problem after I updated yesterday.
I find that if I am on battery power I can only maintain a wireless connection for 2-5 minutes. AirPort shows that I am connected, but I cannot access webpages or email. If I turn off AirPort and turn it back on sometimes I get reconnected to the internet. The other times my computer crashes and I get the slow gray screen that tells me to reboot.
Strangely, if I stay plugged in to power I have none of these problems. I would therefore assume that yesterday's update somehow effected the power settings for my wireless card. However, all of the settings I can find look good to me. I am a Mac "newbie." Is there any way to go back to remove an update or go back to a previous system set up? I live about an hour from the nearest Apple store, so I am hoping to avoid a trip to the Genius Bar. Suggestions?

joe,
thanks for the heads up on the power supply. that could have had more to do with my own solution than the wep and the launching of internet connect. my battery was running low and i did plug it in about the same time i was working on the connection. when i get a chance, i'll see if i can duplicate what you've experienced re power supply. we may have the same issue and maybe we'll be able to narrow it down. i'm close to an apple store and it's easy for me to drop in after work on the way home. i may be able to save you a trip. i'll report back later next week as i'll be out of town over the weekend.

I have duplicated what you reported about computer working fine plugged in but crashes when running off battery. I will try to get in to the Apple store on Monday or Tuesday. In meantime I guess we need to stay plugged in.

I drove over to my nearest Apple store today and naturally the problem wouldn't appear while I was in the store. The Genius took a look at my error logs and could see the problem I was having, but he didn't really have a fix for me. He did suggest rebooting from the CDs that came with my computer to reinstall the operating system if I kept having kernal panics.
Of course, when I got home the problem reappeared when I was running on battery power...my computer also had another kernal panic. Part of me started to wonder if it is a problem with my wireless router. However, I also have a MacBook still running 10.4.9 and it isn't having any problems nor is my PC laptop.
I finally gave up and plugged in the power supply. Since no one at the Apple store seems to be able to fix my problem I am hoping the "software update gods" find the error with this week's update and release a fix. Otherwise, I am going to have to dig out those CDs. How hard is it to reinstall the operating system? It sounds daunting.

My husband has 1 of the newer macbook pros that runs off of lion and know his computer wont let him get past the starting screen it keeps telling him to put in a bootible disk he cant use his key board or anything what should he do?

Hi...
Use Lion Recovery to repair the startup disk if necessary, or reinstall the Mac OS X.

You'll need to use a wired (USB) keyboard.

MBP Won't Run Off the Battery

I've had my computer for a little over a month, and the other day it stopped running off the battery. Everything is fine when I have the AC adapter plugged in, but the computer won't start up if it is disconnected. I ran the computer off the battery more often than not before this started happening. I removed the battery and put it back in a few times, but that didn't help. Has anyone seen this before? Thanks!

Mine did almost the exact same thing.
A few days after the update, it started registering 32 hours of remaining charge (33500+ MhA), and one day, all of a sudden, the battery just died.
Mac OS says there is no battery installed, obviously it won't charge or run on battery power, when I press the LED button it does nothing. It's just dead.
My machine is almost 2 months old... I called Apple and complained about this whole thing, because my machine has almost every other defect out there, including the whine, the almost unbearable temperatures, the moo, and the LED buzz... so I told them that enough was enough and that I wanted a new machine.
They just said I sould drop it off at the Apple Center, and THEY would decide if should get a new machine.
I feel so terribly frustrated. How is it possible that you spend $2000+ Dlls on a machine that after just 2 months does all these things, and still be treated unfairly, like an idiot, with arguments like "It's our decision if we replace the machine, or repair it..." ??
This is just not fair. But what can we do, right?

Powerbook won't run off of battery - requires PMU reset to power up with AC

Like everyone else posting here, my powerbook won't run from the battery. I have two batteries, one that came with the computer 3 - 4 years ago and a newer one that I purchased about 1 year ago. When I am plugged into AC using iStat Nano the newer battery shows cycles 173, health 89%. The older battery show cycles 0 and health 100% (go figure!). Both batteries just say 'calculating' on the tool bar battery meter. The light around the AC adapter plug always shows green as if the batteries are fully charged.
Here is where my post differs from the others. Once I shut down the computer I can't power it up again with reseting the PMU. I've tried reseting NVRAM and deleting and re-establishing the powermanagement plist as suggested elsewhere on this forum to no avail.
Is the PMU something that can be replaced? How is it related to DC-IN? I've read elsewhere here that is another problem that could cause these symptoms. Has anyone had these two components repaired and did it fix the problem? How much did it cost?
Thanks in advance for any information you can give men.

I had the same experience. I have 10.4.10 on the cloned drive but the battery is still not charging. I decided to take a closer look at the battery updater instructions and discovered that even though I am at 10.4.11 on my Powerbook the BatteryUpdater.bundle was at revision 1.1.3 and hadn't been updated since Jan 6, 2006. So I downloaded the BatteryUpdate that is posted at the top of this forum and installed it. It has made no difference in the operation of the computer. The AC adapter still isn't charging the battery although the green ring light is on which usually indicates the battery is charged. furthermore, when I go back and look at the date and version number on the BatteryUpdater.bundle they haven't changed. Who knows what the update actually changed! There is no mention of it running in the software update log. My system profiler says:
The battery is installed
Full charge Capacity 3890
Remaining Capacity 0
Cycle Count 173
AC adapter cannot charge battery: YES
By the way, my battery is a replacement battery.
I have just about exhausted all my option other than taking it into an Apple repair store and I'm not sure at this point I want to give Apple any more of my money. I am going to live with it the way it is for a while in the hopes that someone will post a fix for the problem. Good luck with your investigation. If you find out anything else please post it here as I will check back on a regular basis. If I find out anything else I will do the same. Nice working with you.

Any advice will be appreciated,
Many thanks

Welcome to the Forums!
Your battery is on the way out. You might be able to get a new battery for free under AppleCare. There are known issues with Sony batteries (yours is one) that have been acknowledged by Apple. They extended the battery warranty to two years for Core Duo machines, but lots of users with C2D machines have also gotten free replacements. Details on that program are here:
http://www.apple.com/support/macbook_macbookpro/batteryupdate/
The catch is, Apple spec is that a battery maintain 80% health for 300 cycles, and your cycle count is 317. 80% health for you would be a full charge capacity of 5000 mAh, and you are under that by a bit. Apple considers batteries to be 'consumables' and thus they aren't covered by the warranty if they fail due to 'normal use'. Nevertheless, others with your symptom and up to 400 cycles have reported getting free batteries.
So, I would contact AppleCare or visit an Apple Store. Be polite but firm. It may help to bring in a printout of the linked page, as some Apple 'geniuses' are apparently unaware of this issue.
Hope this helps...

MacBook won't start on battery/shuts down when power adapter is removed

Help & advice needed please.
My MacBook won't start without external power, it gives a whir then a click then nothing. Once started up, if I remove the external power it just shuts off.
The battery shows at 98% & charging. Coconut Battery shows the following:
Current battery charge 4126 (& increasing as I type)
Maximum battery charge 4200
Current battery capacity 4200
Original battery capacity 5200
80%
Battery loadcycles 111
Age of your Mac 6 months
Charger connected yes
Battery is charging yes
Does anyone have a clue why the Mac won't power itself on the battery when everything else seems like it works?
Cheers!

As of today, my MacBook and I have been together for 40 days. Yesterday, while I was happily surfing (on battery), it powered down with no warning. Okay, these things happen. I plugged it in, restarted, and all seemed to be fine. Battery was about 70%. I did other things on my other machines and when it was about 90%, unplugged it and everything was good. This morning after using it unplugged for 1.5 hours it did the same thing, but decided to only work with the power adapter, not on battery alone. When trying to boot without AC, it would try to spin the CD and then fall back into off. When on AC, if I pulled the adapter, it would last two seconds and go blank. I made an appt. with the Apple store (Fashion Show Mall, Las Vegas) for 3:20pm. I got there right at 3:20pm and the monitors showed I was 5th in line. Store was fairly packed, at least one patron at every display item. Monitors also said the next MacGenius appt. was "approx. 8:30pm." Glad I made an appt! I was served about 15 min. later, during which time the monitors had changed to "No more MacGenius appts. available today, please try tomorrow." However, one guy came by without an appt. and was told he would be put on standby and to come back in 30 min.
Once I explained my issue with my MacBook battery, my Genius tried one of his batteries. "I just want to make sure it's your battery and not your motherboard." My machine worked fine, so he said "No problem, I'll have you out of here in 10 minutes." He got me a brand new battery, tested it, and put my old one in a box on the rear counter with four others. He pulled the serial number from the "About this Mac" area, didn't need my receipt for purchase date or anything. I had even printed this page: http://www.apple.com/support/macbook_macbookpro/batteryupdate/ to use as ammunition, but didn't need it. He did approve highly of my dashboard widget "iStat pro", available here: http://islayer.com/.
So the battery issue is a very common problem, and one that Apple has tried to deal with as painlessly as possible for the consumer. My Genius did ask if the battery showed an "X" in the icon bar, and I said no. Just wouldn't run on battery. On the way out of the store, one of the 3 MacBooks, in fact the one closest to the door, had an "X" on the battery icon. When I unplugged the power, it shut down immediately! The moral of the story is to contact Apple immediately with problems and give them a chance to fix them. Hope this helps others.

Hi mariocedeno,
Let's try resetting the SMC and see if anything changes:
http://support.apple.com/kb/HT1411
If that does not resolve the issue, the next scenario would be to try a different charger and battery to see if anything changes. Based on the information provided in System Profiler it's not immediately obvious if we're dealing with a battery, charger or CPU related issue that's causing this.
If you don't have access to another charger & battery, our next best course of action is to arrange service/diagnostics via an Apple Retail Store or Authorized Service Provider. Is the unit still covered by Applecare/one-year limited warranty?

Disconnecting when running off battery

Everytime i remove my power cord from my MacBook Pro, i have trouble keeping ichat connected, my ineternet it fine, everything else stays connected, ichat is the only problem. It will usually stay connected for only 10 minutes or so, and when it disconnects it doesn't usually tell me at first, my friends will tell me i disconnected about 3 minutes before it actually tells me. I also tryed changing my power settings, to never putting the drivers to sleep and such, but that didn't work. Any help would be appreciated, thanks.

I have the same problem! as long as i am connected to AC power i chat stays connected no problem. If i run off the battery I continualy get disconnected. My disconnects work the same way as yours. the person i am chatting with sees me disconnect right awat but on my side it looks like i am still connected for several minutes. it even seems to accept my outgoing messages without telling me i am discconected.
Its rather annoying. Everytime there is a pause in the chat i find myself asking "am i disconnected?"

Battery not availble BUT still running off battery!?!

So yesterday, my MacBook decided to not show up... what? Randomly, out of the blue! It had previously been working just fine, about 80% health, and then, all of a sudden, it stops recognizing that there's a battery installed. Here's the funny part, though... The battery still has a charge (as shown by LEDs on the bottom), and the MacBook still runs off the battery, despite it saying it doesn't have one! Unsurprisingly, the battery doesn't charge either.
The computer will only start up if plugged in, but can subsequently be unplugged to run on the remaining battery power.
It seems the problem here isn't the capacity of the battery, but the communication between the battery and the computer.
I've tried resetting the SMC and cleaning the contacts of the battery, but neither of those had any effects.
Do I have any recourse besides trying/buying a new battery?

I have the same exact problem...totally out of the blue. You definitely don't need a new battery because my problem started couple of days after I purchased a brand new battery.
I think it might be the battery connector to the logic board. In almost all other cases with this problem, when the battery isn't recognized by the mac, then you have two of the following: it doesn't charge AND the computer doesn't run off the battery alone, even if the battery indicates that it still has juice left.
Unless instructed otherwise, I'm going to open up the computer and re-connect and clean the battery connector.
Also, do you have the updated battery software?
