I just had my battery replaced because it was draining too quickly however after getting it back it still doing the same thing. What should I do?


MacBook Pro, Mac OS X (10.7.4), Bought in Taichung, Taiwan

    There are different reasons why the Mac drains your battery quickly. First of all, reset the SMC > http://support.apple.com/kb/HT3964

     

    If it doesn't work, there's a process that is consuming all CPU and RAM. To see what's causing this, open Activity Monitor (in /Applications/Utilities). Then, choose "All Processes" in "Show", in the toolbar. Finally, order process by real memory and tell me if there are processes that are consuming a lot of CPU or memory

    Thank for that!

     

    It was draining 1% every 3.5 minutes, now its gone up to 4 minutes.

     

    I reset the SMC and this is what my activity monitor looks like now.

    Set Activity Monitor '%CPU' to show values from high to low.  I suggest you get rid of Chrome.

     

    Ciao.

    This shouldnt be the problem, because I used Chrome even before the battery started draining fast.

     

    It all started when I changed my charger from a 60 to a 85W

    This change should not have an impact unless there is something wrong with the 85 w replacement charger.  Try another charger if available or have it checked out at an Apple store or AASP.

     

    If you look at some of the discussions in these forums regarding Google Chrome you will find that the application is not well designed for Macs and has often been a source for problems.  Keep it if you wish but I use Firefox, Safari and Opera, in that order.

     

    Ciao.

    The WindowServer process is using too much CPU time.

     

    Please read this whole message before doing anything.

     

    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.

     

    Step 1

     

    The purpose of this step is to determine whether the problem is localized to your user account.

     

    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”

     

    While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.

     

    Test while logged in as Guest. Same problem?

     

    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.

     

    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.

     

    Step 2

     

    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, or by a peripheral device.

     

    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.

     

    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain iMacs.  The next normal boot may also be somewhat slow.

     

    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

     

    Test while in safe mode. Same problem?

     

    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

    Thanks for that,

     

    Im a little confused about the step one test. Do you mean SMC?

    Ive enabled the guest user Screen Shot 2013-06-28 at 11.14.00 AM.png

    Ive enabled the guest user

     

    OK. Log in as Guest and see what happens.

  • 11. Re: Draining battery

    I logged in as a guest and the battery life draining was approx 1% every 5 minuutes.

     

    On Safe mode it was about 5.5 minutes.

     

    This is without doing anything on the computer.

    I logged in as a guest and the battery life draining was approx 1% every 5 minuutes.

     

    Where are you getting these estimates? If that's literally true, then the battery would take more than 8 hours to drain completely, which is hardly a problem.
