Laptops :: Macbook Pro With Finished Battery?
Jan 28, 2010
I've got a late '06 Macbook Pro, running OS 10.4.11, 2GB RAM, 2.16GHz processor. The battery recently died, but that's not a problem as I run it via the power adapter when at home.
Problem is, since the battery packed up, the computer itself is running slower than when the battery was installed. Is this usual?
It's a dualcore processor, and was previously fast enough to watch HD movies, but now HD movies are jerky, and the whole overall operating system seems noticeably more sluggish.

I have had my macbook for about 2.5 years. The past few weeks i have noticed some type of battery issue.
First I noticed that the led light on the charger was going back and forth between green and orange (charged and charging) (every 2-3 seconds).
I also noticed that on my top right part of my screen where battery life is shown it keeps going back in forth between (calculating....) and (Charged symbol: time).
Secondly, after about a week or so my battery started dying within 5-10 minutes after being unplugged.
Third, now my fan seems like it is always on high.
Is my battery just dead?

Unfortunately i was away from home for the last 3 months and i forgot to remove the battery from my macbook pro 2,2.
Now when i use the macbook pro it turns off suddendly when the battery is at 79% charge.... I tried to callibrate the battery and reset the SMC, but i see no change...
Is the battery dead? And even if it is shouldnt i get a warning or something before it goes dead?
Is there anything that i can do or should i start looking for a new battery? I must mentione that this happened also after upgrading to snow leopard.
I do not know if it has anything to do with it, but i remember when i upgraded to leopard i had my battery replaced under warranty cause the computer would turn off suddendly when the battery would each 30%...

I let my new mbp(mid 2012) battery run down. It was on, I walked away for one minute and came back and the mbp was shut down. I plugged in charger and the mbp won't turn on at all. I got it on Tuesday so it is brand new.

I just bought a new MacBook Pro with a solid state (flash memory) disk. The battery life is good while I'm using it, but if I leave it with the cover off for a few days (asleep, I assume), it'll be mostly discharged when I open it up. I assume this isn't normal - it shouldn't be losing that much charge when closed and hibernating. I don't have "wake for ethernet access" checked, if that makes a difference. What's going on - why won't it hibernate?

I recently spilled coffee on my mid 2010 2.4ghz macbook pro. After drying out, the computer worked fine, although the battery was not recognized. Since apple does not cover water damage i bought a replacement battery and installed it today. After starting up the problem is not solved. there is still an X through the battery indicator and if i unplug the laptop it shuts down instantly. When i turn it on, the status LED on the front blinks 6 times before the laptop actually boots up. I have reset the SMC, NVRAM and PRAM.
Any help or input would be greatly appreciated.

Mac Book Pro shuts off when using the battery after about 20 minutes. System Profile information says it is fully charged. Health Information, cycle count:108, Condition: check battery. I believe I have two weeks left on the Applecare Protection Plan.

I have a white macbook core2 duo. The main battery is dead and I have been using it with the power brick.
Lately when I plug in and start up I have to go through the reset time and date etc.
I have heard that some of the newer laptops don't have the back up battery. Does this one, and how do I get to it to change it?

I've been looking for some info on the older 2007 MacBook Pro battery specs and stats, etc., but have been somewhat unsuccessful. Lately my MBP has been draining the battery at a much quicker pace than normal. This machine is only a year old now (however CoconutBattery says the battery is 16 months old). Still, the battery capacity shouldn't have diminished too significantly. Before I restored the Mac and installed the Windows 7 Beta, I could average 3-4 hours on a full charge. Normally, I would keep WiFi + Bluetooth enabled, an external monitor attached, several USB peripherals plugged in, and the main display would be set to maximum brightness. 3-4 hours was pretty nice considering the amount of power the machine could have been using.
After I partitioned my hard drive, the battery life was cut in half on the OS X side. Windows 7 power management was even worse. I figured that there may have been extra disk activity causing this problem. After I finished toying with Redmond's new OS, I removed the Windows partition and moved on from there. I know after I removed the partition, I was getting excellent battery life initially. Once that short period ended, it went downhill from there. The battery meter has become surprisingly accurate as of late; in a minute or so, you can easily watch the percentages drop 1-2%, which appears abnormal. I can manage 3 hours on a single charge at best, but I usually get less. I decided to take greater care in cycling the battery, in hopes of nursing it back to health, so to speak. It doesn't appear to be working so well. Enabling WiFi and other peripherals only drains more power, but turning them off again adds only 5 minutes. So when I'm using several devices at once, I'm lucky to get a little over 2 hours. Turning off menu items and background apps does nothing either.
It's been this way for several weeks now, and yet, iStat, System Profiler, and CoconutBattery all report seemingly acceptable and consistent battery info: 86% Battery health, around 180 charge cycles, and the capacity is around 4700mAh (out of the original 5500) for now. The computer believes all is well. Performance says otherwise. I'd like to think that physically the battery seems to be okay. I've cycled and calibrated it several times. I have read reviews that indicate that Santa Rosa MacBooks with new batteries have averaged similar runtimes to the ones I experience now, but I know mine has usually bested all of the reported tests. It just seems wrong for the average runtime to go from almost 4 hours to 2 when the battery is (supposed to be) maintaining the same health level. I have AppleCare if it needs to be replaced, since this drastic change in usage time is very noticeable and counterproductive for me, but it could just be the computer (or me for that matter). Is this behavior normal for a battery of this age? What should I look into? If this is normal behavior I can live with it, but I would prefer to get as much out of the one I have.

i know that its generally recommended to not overcharge batteries. i have e.g. seen several cellphone batteries going kaput within a few months since people leave their phones on 'overnight' charge.so i am wondering if the same applies for the polymer batteries in my MBP ?however, if i am not mistaken apple uses some kind of sophisticated electronic monitoring to keep a tab on the state of charge or discharge of the battery.
does this mean that there is no chance of the battery getting damaged through overcharging ?basically, what good practises can i use to ensure that the polymer battery lasts me a long time ?

I believe the mechanism utilized by my laptop to route power either from the battery or the AC adapter, is faulty. Sometimes when the battery is connected to the laptop, the battery is not recognized and the battery icon has an 'X' in it, other times it shows a charge %. Just recently with a full battery, I removed the AC adapter from the laptop and the laptop immediately powered off as if the battery was not in place.
Assessed:
(equipment age) new linear power cable and new battery purchased in september
(connection) linear connection seems stable
(battery) charges and holds a charge
Possibly linear > battery transistor issue? Repair Options?

Every time I try to turn on my computer it immediately goes to the grey screen with the different languages that says you have to hold down the power button until it restarts b/c there's some error. Here's the story behind it. I tried to install windows but Bootcamp wouldn't work. It said I had to back up my computer and reinstall the OS as Mac OS Extended (Journaled) (even though it already was!). But I didn't have an external HD that was big enough. I borrowed a friend's external HD and reinstalled from scratch (without putting my old system on yet).
The Windows installation finished, then said there was an error and to restart. It kept saying that and wouldn't restart. Then I tried going back to my Mac OS, and it immediately went to the grey screen with the different languages that says you have to hold down the power button until it restarts b/c there's some error. I even tried reinstalling my old system and it still did this. The disk repair utility said everything on the Mac OS should be fine, though. Eventually I was able to reinstall it clean from the Snow Leopard DVD, but now I can't get my old computer back or windows on it!

How do I delete, once and for all, tv shows that I keep trying to delete from my iTunes library? They never finished downloading and I keep deleting them but, they keep coming back when I click "download all" or when I enter a password? I don't want to allow them all to download then delete as there are about 30 of them?

Just finished using Onyx on my laptop and asked it to repair preferences. All went well until I read the bottom line which said the settings for the SUID file "system/Library/coreservices/remotemanagement/ARDAgent.app/contents/MacOS/ARDAgent were changed and unrepairable. Why would they be changed and how do I get them back to "normal"?

I have just completed rescuing a water damaged MB C2D which was originally a 2.16 and is now a 1.83. Fun project for a cold Sunday afternoon. 5 hrs I have one issue with the MB and that is the charging of the battery. The battery icon sometimes shows 'no battery' or if it shows a battery is recognized, it isn't charging. The LED on the mag-safe charger is always green. The battery is from the water damaged 2.16 and my thinking is that it may have suffered damage from being exposed to water. Original owner left the MB in the backyard and it started to rain!

My battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged.
When I put the brand new battery on the lap top, the computer shuts down halfway through boot up. I tried holding the power button down through boot up reset, as well as removing all power (plug and battery) and holding down the power button for 10 seconds reset.

I calibrated my battery for the first time since Dec. When I plugged it in this morning, it took 3 hours to charge all the way, and now it's stuck on 99% full, 0:00 till completely charged, and I'm getting an error when I click on the battery in the menu bar that says "Service Battery". When I click on the error, it tells me that it may not be functioning properly and to take it to an authorized apple service retailer. Before I waste 2 hours by going to the Apple store and back, has anyone else had this problem, and is there a way to fix it without having it looked at?

I get the whole part about that I set my laptop to go to sleep in 5 minutes, and if I close the lid it'll go to sleep, and the little light at the bottom starts to pulse, etc. But in sleep mode, my battery seems to drain extremely fast!
For my old Gateway M275 laptop while in sleep mode, it would probably lose about 5-7% of it's battery in a day's duration. With my MacBook Air, I just came back to it tonight after a day's worth of sleeping, and my battery was down to 16% from 29%. And to check, it was indeed sleeping!

If you look at apple's battery life page it states the MBA battery is removable, I thought it wasn't supposed to be?Battery Lifespan For Apple notebooks with removable batteries ? such as the MacBook, MacBook Air, and 15-inch MacBook Pro ? a properly maintained battery is designed to retain up to 80% of its original capacity at 300 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.

I have an early 2008 non-unibody MacBook Pro. For about a year now, the status of the battery has been "replace soon." I was still getting a pretty good amount of time off of one charge so I wasn't too worried. This past Saturday morning, I woke up, checked the battery indicator lights on my computer (it had been sleeping since the day before) and it said it had about 60% percent so I opened it. I was on the Internet for about 10 minutes before it shut off without warning.
It wouldn't turn back on when I pressed the power button, so I plugged it in and it turned back on. When I checked, the battery status was "replace now." After using it, I turned it back off and left for NYC for the weekend and didn't bring it with me. When I got home last night, I plugged it in and tried turning it on with no luck. The battery indicator light was flashing one light, so I just assumed it would need to charge for a bit before it would turn back on. After about two hours, when I went to bed, it still was flashing just one light. I kept it plugged in over night, and this morning when I checked it, the battery indicator lights showed that it was fully charged, but it still wouldn't turn on. I still kept it plugged in throughout the day just in case, but it still won't turn on even though all the lights are lit. Is the battery just showing me false information, or should I be worried about more than just the battery?

purchased a macbook Unibody back in October 2008 when they were released and use it heavily. The battery no longer holds a nice long charge - I get about 2 to 2.5 hours out of a full charge.
The battery has 149 cycles on it, which is obviously high (and correct, I use the hell out of it). With it still being in warranty, is it worth pursuing a replacement battery? Will Apple tell me to go take a hike with the high cycle counts?

i just ordered a late 2008 macbook pro 15 with the dual GPUs (9400m and 9600m GT) and I'm a little worried about the battery life.
-What can I expect if just doing normal every day stuff (web surfing mostly?)
-does watching a movie off of the hard disk use less battery than watching it off a DVD? Is there a big difference?
I'm not a big gamer but would like to have the horsepower to play a game should one come out that I want. I'm also not a big traveler so battery times are only of average importance.
Basically, I'm asking if I made a good purchase considering I have only average concerns for both battery and game performance. They had the new 7 hour battery 15" macbook pro for the same price but it doesn't have the dual GPUs.

been using my older MBP with windows 7 for a while and have never notice oddies with the battery until now. Then recently after replacing the failed HD and re-installing Snow Leopard on my 2007 MBP, the battery panel is telling me "Service Battery"; it's battery health according to coconutBattery is fair for it's age (50%).
the unit (battery) has been replaced previously due to being considered 'under performing'. Is Snow Leopard trying to encurate it's users to replace the battery more frequently? If not, does anyone know why this appears? I'm at lost, since it appears to work fine, if not charging completely.
