How do i know if I need to replace the battery in my MacBook Pro?

How do i know if I need to replace the battery in my MacBook Pro?

There are a few ways (none of which are covered in the above link). On more recent OS X versions, when you click the battery icon in the menu bar you may see a "Service Battery" or "Replace Now" message. If you aren't seeing that, the system probably thinks the battery is fine.
Also, in your System Information utility, there is a Power section that provides Health information for the battery, with a Condition status and Cycle Count. If the Condition is Normal and your battery is under 300 cycles (for removable batteries) or 1000 cycles (for non-removable batteries) it is not time to replace it yet.
But of course, the other time to replace it is if you don't think you're getting the runtime you want out of it.
If none of those is a problem, don't worry about it.

  • How will I know it's time to replace the battery?

    Fully charged, the battery has never had more than a 2 hour life in my 17" Powerbook G4.
    Surgical history might be relevant. Last summer Applecare replaced a dead hard drive. Last week Applecare replaced the power input, the case and the keyboard after perplexing power supply problems -- no keyboard light, Airport card wouldn't work on battery power, Energysaver would give haywire readings and Powerbook would run out of battery suddenly, two power adapters were killed in two weeks. I reset the PMU before visiting Applecare to see if that fixed the problems. I wasn't convinced it did.
    I've got 350 cycles on the battery. I've haven't calibrated the battery monthly on a schedule, but I've had no shortage of running it down to sleep and recharging.
    Fully charged, the battery has never had more than a 2 hour life. That's with no peripherals attached and with the display set to automatically adjust to ambient light, energersaver set to normal, processor set to automatic.
    Is that all?!? 2 hours? That's the price of a big screen?
    One serious suggestion: read the Apple support doc, http://docs.info.apple.com/article.html?artnum=75448 on the proper power cord for your portable. I harbor concerns that the wrong adapters are being sold to Powerbook users and that those adapters are a very bad thing for electronics. I have run through four adapters in the short 3 year life of this single Powerbook. They are fragile and unreliable.

    There's more to it than that. CPU demands, drive demands, and wireless transmitters also place heavy burdens on the battery. I get a bit over 2 hours on a new battery, but when I go on a long plane trip, I can see the difference. On a long plane trip, the cabin is often darkened, so even the lowest backlight setting is plenty and so the screen uses much less battery. In addition, the airlines make you turn off the wireless, so having the AirPort and Bluetooth radios off also saves energy. Under those conditions, and if I set the CPU to Reduced and don't make it work too hard, yes I think I did see it exceed 4 hours once. But in day-to-day use, with the backlight turned up, wireless networking turned on, and the CPU grinding away at graphics and video and music and web page rendering, everybody gets about 2 to 2.5 hours.
    It's just like gas mileage on your car. I would love it if I could always have the fantastic mileage I get by extended drives on the highway, but life isn't like that and in reality I don't come close to that figure because I have to drive around town stop-and-go.
    AppleCare: Over 3 years, the value of covered repairs on this laptop exceeded the cost of AppleCare about 3 times over (US dollars), so it turned out to be a good deal for me, as it has always been.
    When to replace your battery: Replace it when you can't stand it anymore, and that point is going to be different for different people. I think I waited until my battery was down to about 45 minutes. Below that it was hard to get any meaningful work done. Someone who regularly needs more than an hour of battery time would have gone for a new battery sooner.

  • HT5243 How does one know if they use "java applets"? What do they do? How will I know if I need to 'disable the java web plug-in browser' if I do not use them? ( I'm not very literate in computer-speak.

    How does one know if they use "java applets"? What do they do? How will I know if I need to 'disable the java web plug-in browser' if I do not use them? (Obviously I'm not very literate in computer-speak.)

    Well, when you go to a web page a section of the web page will have a coffee cup picture where the java applet will run. The applet loads then runs. If you are not seeing this behavior then you are not using java. If it make you feel more comfortable then disable the browser java plugin. On my machine I have not disable java- but you
    may what to.

  • My iphone 4s is over 2 years old and I need to replace the battery. How much will this cost at an Apple store?

    I have an iphone 4s that is  over 2 years old. The phone's battery is no longer able to hold a  charge for an acceptable length of time.  Assuming I need to replace the battery, how much will this cost at an Apple store?

    Basically, I'm new to Apple, despite using them before, but I've never actually owned my own.
    Since buying this phone off a colleague at work, I seem to be having problems with it. First, I noticed how rubbish the battery life is, then my charger almost went up in flames and thirdly my camera lense is scratched beyond belief.
    I know the phone isn't within warranty, although I was lead to believe it was before and during buying it, so basically I'm extremely disappointed with the general make up of iPhone's considering they cost such a **** of a lot of money, you'd think they'd be built to last.
    Back to my main point, how much would it cost for a new battery? Or a new camera lense if anyone can help me with that? (I know that the back of the phone was refurbished just before my buying it, so literally just the camera lense)
    Thanks!
    So basically it sounds like you bought an abused used iPhone and somehow that makes the phone subpar because dispite the abuse it should still last forever and look like new? Batteries don't last forever, even under ideal conditions, so your expectatoins are unrealistic. Take it in and have an estimate done.

  • I'd like to replace my hard drive.  How do I know what to buy for my 15-inch early 2008 MacBook Pro?

    I am out of room on my hard drive.  I'd like to get a new hard drive and restore my data to the new drive from Time Machine.  How do I know what kind of hard drive to buy for my 15-inch, early 2008 MacBook Pro?  Also, how hard is this to do? 

    I have changed HDDs several times on the old MBP.  Currently it has a Hitachi 500 GB HDD that came out of my new one.  My adage is that one cannot have too much storage and I think that the 1TB HDD is an excellent choice.  Not only do you get generous capacity, the performance should be (theoretically) comparable to a 750 GB 7200 rpm HDD.  I will be very surprised if there are compatibility problems.
    If you bought the HDD from OWC, you should have received Installation instructions.  If not, go to the OWC website and look at the video.  I actually downloaded it so that I could hand write the instructions down step by step.  Also check out iFixit website.  They have step by step instructions that may prove to be useful.
    Tools you need:  00 Phillips and #6 Torx Drivers (get good ones).   The instructions make mention of a plastic pry bar (spudger).  I use a stiff piece of plastic like a credit card.
    Tips to keep in mind:  Get a large open table space and place a large clean towel on it.  That will protect your MBP and when you drop a screw (and you will) it will not bounce far so you will not have to spend an hour looking for it.
    As you take out a set of screws, keep them together (I use wide masking tape.  The little screws will stick to it.)
    Keep the sets in sequence.  That will make reassembly much, much easier.
    The most difficult steps are removing the keyboard from the MBP body and removing the ribbon cable from the mother board.  In case of the former, work from the back (the display) to the front.  You will initially have to pry it up and then do a lot of jiggling to remove it.  Don't be too timid about it.  At the end of the ribbon cable there is a rectangular connector.  Use your credit card to remove it.  Just pry it off.
    The #6 Torx driver is used to take off the 4 mounting pins on the HDD and if I remember correctly there is another place where it is needed, specifically in the battery compartment ( I think).  If the instructions don't say so, keep that in mind and inspect the screw before you select the driver.
    Good luck and make sure that you don't have parts left over.
    Ciao.

    You have to bring your charger with you and hope their is an electrical outlet that is compatible with your charger near the seat you are sitting in.  I do not know of any other way.

  • How do I stop unnecessary programs from running in the background on a Macbook Pro 2010?

    Hi recently I bought a Macbook Pro OSX 10.8.3 2010 (2.4 GHz Intel Core / 2GB 1067 MHz DDR3). Im pretty content with it considering its my first Mac. Up until recently I had no problems with its speed.
    My brother directed me to the activity monitor and showed me how to quit a program. However there are still a several running programs I do not recognize and/or do not use (such as photo stream, Calendar Agent, UserEventAgent, Notification Center, AppleSpell service, cfprefsd, talagent, xpcd, imagent, com.apple.dock.extra, fontd, loginwindow, SystemUIServer, tccd, usernoted etc etc etc UGH!! The list just goes on and on. There is a circular graph at the bottom in pir form highlighted with the colors green, red, blue and yellow indicating what is taking up space or speed? If I quit Safari a huge portion of the green is highlghted. but I can not seem to get it to fill the majority of the pie graph. I see there are all these running programs (most of which I do not use or recognize) but I cannot get them to quit even if I highlight it. How can I stop this? Quite frankly its so frustrating. Again I am new to Mac.
    Thanks

    First, back up all data immediately, as your boot drive might be failing.
    There are a few other possible causes of generalized slow performance that you can rule out easily.
    Reset the System Management Controller.
    If you have many image or video files on the Desktop with preview icons, move them to another folder.
    If applicable, uncheck all boxes in the iCloud preference pane.
    Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
    Check your keychains in Keychain Access for excessively duplicated items.
    Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
    Otherwise, take the steps below when you notice the problem.
    Step 1
    Launch the Activity Monitor application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
    Select the CPU tab of the Activity Monitor window.
    Select All Processes from the menu in the toolbar, if not already selected.
    Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
    Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
    Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
    Step 2
    If you have more than one user account, you must be logged in as an administrator to carry out this step.
    Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
    View ▹ Show Log List
    from the menu bar.
    Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
    When posting a log extract, be selective. Don't post more than is requested.
    Please do not indiscriminately dump thousands of lines from the log into this discussion.
    Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.
