In 'about this mac' the battery condition says 'check battery'. Should I be worried?
Hey guys,
I've been looking at replacing a few parts for my macbook as it is getting a little old and beaten up now, and I don't have the money to buy a new one at the moment. I have just been searching through everything to see if anything is wrong. Mine is a white macbook from late 2009. So far I've had the bottom case replaced because the rubber was starting to peel off and was very scratched.
Now I am looking at getting my trackpad replaced (or fixed) as it is stuck down and doesn't click anymore. I've tried cleaning it incase there was something stuck in it, but hasn't worked. After some research I've found that this could be due to a swollen battery. I had a quick look at it when I replaced the bottom case but it doesn't look like it has swollen. So I checked to see the conditon of the battery and it says 'check battery'. I am only up to charge cycle 299 and there is no problem with charging it or its charge life (not that I've noticed anyway). Could there be another reason as to why it says this?
Firstly the trackpad could easily be due to the trackpad screw not being at the correct depth, easily fixable especialy if the tap to click works.
As for the battery check battery usually means the battery has become faulty in some way. You could try an SMC reset with your adapter plugged in. (Shift-Option-Command-PowerButton at the same time). Your battery should still work but 299 is way too little for a your year MacBook needing to be replaced.

Battery condition says "Check battery"
I have a MacBook Pro 2.33GHz Intel Core 2 Duo, and am now on my third battery, which is now only 12 months old. The nice people at the Apple Store gave it to me at no charge because my first two batteries had such short lives. Currently System Profiler says "Check battery" and that full charge capacity is only 3368 mAh after only 43 cycles.
Why do these batteries not last well? Dying after only 43 cycles? I need to return to the Apple Store for a fourth battery?Hi Mactrix,
I did try that, and unfortunately, without warning, the machine shut off as I was sending mail and Mail got corrupted. I've calibrated the battery before, and always got a pop up that warned me that the machine is now running on reserve power. After the "reserve" ran out, it would sleep. But this time there was nothing, just a "click" and darkness.
Took the machine to the Apple store, they hooked up an iPod nano running a battey test program which said the battery was bad, Because the people there are so nice, they gave me a new battery (because it had so few cycles on it). No wonder Apple support is rated so high.
Fortunately, I could restore Mail from TimeMachine - although there are some quirks I'm working on. -
My battery is not charging but from About This Mac the battery seems good condition. HOW?

I tried a different charger myself (the power source is reliable). But it does not work too. I think I need to bring it down to apple shop.
But is quite disappointing with the new apple product I have. Cos not only my battery is not charging, my built in speaker, the sound is like broken too. So I can hear some noisy sound when I play music.
I have a power book G4, and the power book, everything is still in good condition. Imagine how many yrs I have with the power book G4. This power book I never bring to do any services before. I sometimes really suspect is it Apple drop quality
(cos the office new bought mac from my boss, the USB port is not working too..)
But thanks all for the reply I think I need to bring it down to apple shop. Thanks! -
I looked up serial number in About This Mac and Support site says it isn't
I can't find my Apple Care plan or read the bottom of the computer but I looked up the serial number on my iMac under About This Mac. I copied and pasted it into the box to get a call for technical support and I get a message saying it is not the right number. Now what? How can I call them to get support without the number?
A valid Apple product serial number is eleven characters long, does not contain the letters I or O—though the numerals 1 and 0 are valid characters—contains the numeral 0 though 9 in the third position and the numeric string 01 through 52 in the fourth and fifth positions.
On your model, it's found screened beneath a barcode on the underside of your foot, or can be found as you were instructed using About This Mac or using the System Profiler application. If your logic board has been replaced and is not the original unit installed at the time of manufacture, your logic board may not have the serial number embedded in firmware. In that case, it is not available to display using the About This Mac dialog or the System Profile application.
The most reliable source of such information is typically the number screened on, inscribed or affixed by label to your Apple product. -
Serial Number in About This Mac and System Profiler says "System Serial#"
I recently had my hard drive and motherboard replaced under warranty.
I wanted to check the expiration of my warranty so I could buy AppleCare before my year is up. I went first to About This Mac, and then to System Profiler - both of them say my Serial Number is "System Serial#" - any ideas on how to get my real serial number displayed?How strange! I'm not sure if this will show anything different, but you can also try to get the serial number via Terminal. Just open the Terminal application and copy in this command:
ioreg -l | grep IOPlatformSerialNumber -
Is About this mac/more info/power reliable for battery capacity assessment
Hi,
I calibrated my brand new battery for my Alubook 15". Here are the results :
First cycle : 4200 mah
Second cycle : 4520 mah
Third cycle : 4370 mah
Fourth cycle : 4220 mah
Fifth : 3920 mah.
The battery was sold for 4700 mah.
1. Does this get any sense ? would you worry about future battery performances based on this capacity decrease from the third cycle ?
2. I have read that resetting PRAM may reset this battery power assessment to more reliable data : Any experience about this ?Luc --
You raise some interesting points, at least one of which we debated (without resolution ;-)) prior to the change over to the New Discussions -- that concerned whether the batteries used by the new revision of PowerBooks were qualitatively different than the ones used by previous revisions. I don't think we came to a firm conclusion on this.
But on two other points you raise we did at least draw some firm observations, if not flat out conclusions.
The first has to do with the 10.4.3 update and whether it may have had power management effects for the better. I personally noticed a slight increase in my battery life since the update, which I have attributed (at least in part) to the fact that a process that runs almost all the time in the background (having, I think, something to do with the trackpad and related functions) called "kernel_task" now runs at about half the CPU usage that it used to. It used to regularly consume 7-8% of my CPU resources. Now, when I check in Activity Monitor, "kernel_task" regularly consumes about 2.5-3.5%.
The second relates to the new PowerBook revisions, their greater stated battery life and any hardware changes made in them that may be responsible therefor. Here, I remember reading in several places on these Boards and elsewhere that the type of RAM used by the new PowerBook revisions, i.e., PC2-4200 DDR2 SDRAM (running at 333 MHz), while it may not necessarily be faster than the type of RAM used in the previous PB revisions (PC-2700 DDR SDRAM) (since both types of RAM are running at the same 333 MHz in each model), the DDR2 RAM used in the new revision PBs does consume significantly less power to run. Therefore, it seems to have heavily contributed to the new revision PB's claim to longer battery life. Indeed, I've read that since both RAM types run at the same speed in the PB, it was precisely because of the low power consumption signature of the DDR2 RAM that was the reason it was chosen for the new revision PBs.
Well, good luck testing out your new PB and it's battery. Let us know how it all turns out and, of course, feel free to post back if we can be of any further assistance.
Bonne chance! A bientôt.
Oh, by the way, as for battery capacity and degradation over time and with use, you might find my own statistics to be of interest. I've run off battery power quite extensively since I got my PB in March of this year, and, after 164 complete cycles in about 9 months of use (including may times where the battery was completely drained), my original stated capacity of 4400 mAh has only decreased to 4228 mAh (using the same Apple battery that came with my PB when I first got it). I think that's pretty decent from what I've heard and seen with others.
Later.

My battery status says check battery
Hi everyone
I have a macbook pro retina disp 13inch. i have a problem that based on battery bar menu it says me that check battery. I havent see this situation before. I made the last update from 10.9.1 to 10.9.2 and also made the security update called -002 then i started to see check battery quote in my battery info bar.
my battery options are like this;

About this Mac/Storage Question?
A few months ago, I upgraded my MacBook Pro 9,1 to two drives using OWC's Data Doubler. My main drive is a Samsung 840 Pro SSD. My intent was to use the SSD primarily for the OS and applications. My secondary drive is the stock Apple 500GB hard drive.
Today, I was checking the useable space of both drives and I noticed that my SSD is nearly out of room because of movies, photos, and other stuff. However, because I was concerned about my SSD filling up too fast, I moved all of my movies and photos to the secondary drive many months ago. For the life of me I cannot find the files the "About this Mac" dialog box is saying I have.
How can I locate the files so I can move them? Are there any utilities, Apple or otherwise, that allow me to see a breakdown of the files the "About This Mac" dialog box is indicating?
Thanks!If you are using iPhoto, iTunes, and iMovie, did you
change the library locations in the apps to the HDD?
If not, you will continue to add the data to your home
directory locations.
Just check the Movies, Photos, and iTunes folders
in your user directory. -
When looking at my "About This Mac" it says that I have 60gb of space left on my hard drive, but when I go into finder to find all of these files there is not 300gb worth in anything I search, even searching, "All files on the Mac". Help!?
It says I have over 150 gigs of video on my hard drive. But I have gone through and deleted almost all of what shows up, still it says there is roughly the same amount on the hard drive. Where are these files? I want to delete them so I can have my hard drive clear.
Thanks for your help guys!Quote from the article.
Time Machine in OS X Lion includes a new feature called "local snapshots" that keeps copies of files you create, modify or delete on your internal disk. Local snapshots compliment regular Time Machine backups (that are stored on your external disk or Time Capsule) giving you a "safety net" for times when you might be away from your external backup disk or Time Capsule and accidentally delete a file.
So what makes a notebook any different then a desktop, other then with a desktop you might have your tm backup drive connected all the time.
The object here is to not indiscriminately delete files you need or want to keep. I personally have never deleted a file I wanted to keep.
In essence a backup is for catastrophic failure of your system. So it can be restored once that failure has been fixed. Not because you go in willy nilly and start deleting files. -
I just upgraded to Yosemite. Now when I try to open one particular document in Excel, I get a message that there's not enough memory. I can open other documents. The document I can't get to is the spreadsheet of my passwords. Go figure. When I check the storage under "about this Mac" it says I have 150 GB of 249 GB. I have a MacBook Air. Help please. Thanks, Connie

why would it state under the "more about this mac" that i already have10.8.3 and then in the app store say i need to "resume" do you know what i mean? is it possible i already did download mountain lion entirely once? I am confused and don't want it twice
This is cause by the way the App Store checks to see if an application is installed on your system.
Basically when an app is installed it is in the Applications folder and this is where the MAS looks for them. So it looks at your purchase history for the apps you bought and looks in the Applications folder to see if they are installed. If an app is in your purchase history but not in the Applications folder the MAS says you need to install it.
For normal apps this works fine but the OS doesn;t install into the Applications folder. So the MAS sees you have Mountain Lion in your purchase history but it's not in the Applications folder and so it says you need to download it.
Hopefully one of these days Apple wil fix this.

Well, my title basically asks the question that I am seeking an answer for. Im not sure what year my MB Pro is, and I cant exactly find it on the Apple site. Its a 2.16 Intel Core Duo, 2 GB 667 MHz DDR2 SDRAM. All I see (dating back to 2007,) is Intel Core 2 Duo on the apple site. Im pretty sure (but not 100% positive,) that my MB Pro is a late 2008/early 2009. Just trying to figure out if I can install LION OSX or not, since it requires atleast intel core 2 duo, and mine says I only have the intel core duo. Any help would be appreciated. Thanks!
Core Duo is 32 bit processor and Core 2 Duo is 64 bit processor
OS X Lion, will only on 64 bit Intel processor Mac's.
The following Mac's that have 32 bit Intel “Yonah” processorsthat won't run OS X Lion.
iMac 4,1 Early (Jan-Sept) 2006 17"
iMac 4,1 Early (Jan-Sept) 2006 20"
iMac 4,2 Mid (July-Sept) 2006 17"
Mac Mini 1,1 (Feb-Sept) Early 2006
Mac Mini 1,1 (Sept-Aug) Late 2006
MacBook 1,1 13" (May-Nov 2006)
MacBook Pro 1,1 15" A1150 (Jan-May 2006)
MacBook Pro 1,2 17" A1151 (Aprl-Oct 2006)
MacBook Pro 1,1 15" A1175 (May-Oct 2006)
There is a difference between “Intel Core Duo” and “IntelCore 2 Duo” processors.

I am trying to connect to apple support and it keeps asking me to put in the SN of my MAC and when i do it says that the SN is invalid I am putting in the SN from about this mac and it is the same as the one on the bottom of the MAC any ideas ?
Did you purchase this product direct from Apple online, in an Apple Store, or through a third-party authorized reseller? Or did you buy it from an original owner whose Applecare plan was supposed to be transitioned to a new owner, by them?
Do you have an original shipping carton the unit arrived in?
If the product was a retail 'open carton' purchase and no
back-track is possible, contact the reseller.
And if the computer had seen a major service with logic
board replaced, etc, it may have other issues with serial
number vs one they may have assigned it. Usually a
new logic board may have the SN flashed or if a unit
was determined to be a reman, a new # assigned. But
that would appear in System Profiler, if officially reman.
If you registered a product anywhere with Apple, it would show on a web page along with its serial numbers, going back several years, at this page after you log in there.
https://getsupport.apple.com/GetproductgroupList.action
A blue text with triangle See all products and services opens an Apple ID
sign-in window, then the page changes to show your items & info about them.
If you run the serial number through online Lookup, what appears?
http://www.powerbookmedic.com/identify-mac-serial.php
Not sure if this helps, 'your product' should appear - if registered.
Good luck & happy computing! -
I am a very brand new Mac user. So anyway, when I point to the apple and click on "About This Mac", it says the operating system is, "OS X Version 10.8.2. The question, is this "Mountain Lion", or is that additional software I need to download?

Yes 10.8.2 is the latest version of Mountain Lion. 10.7 was Lion and 10.6 was Snow Leopard.

What do I do? I have already downloaded OS Yosemite (it says so on my Apple>About this mac>overview) but now I keep getting a message from "install Yosemite" that keeps asking me to install Yosemite again and won't go away.
I have the same issue. My computer has also slowed down. I hope this isn't a malware. I haven't input my password into it, and dont know what I did to turn this on.
Hope someone else can give some insight
