HT3964 macbook pro will not start on battery power works fine when plugged in

My macbook pro 15 inch early 2008 model will not start on battery power but works fine when plugged in.

check the battery info.. >about this mac>more info>system report and select "power" on the lefthand column.  How many cycles? What does it say about the condition? etc.

  • Mac Book Pro will not start on Battery Power

    Mac Book Pro will not start on Battery Power although battery at 98% need to connect charger. When started date and time incorrect, comes up as 1st Jan 2012.

    What is the exact model of your MBP?  The date change often is an indication of power loss to the MBP, such as disconnecting the battery.
    If the SMC reset does not solve the situation, post this from your MBP:
    Make certain that the power adapter is connected.
    Ciao.

  • My Macbook Pro will not start with battery connected.

    I have a Macbook Pro which I purchased in 2011 and recently it would not start. I later disconnected the battery and plugged it in and it now works but only without the battery disconnected. When it would not work and the battery was connected, the battery lights indicated that it was fully charged. Any suggestions?

    Was this a used MBP, the 2011 MBPs only have internal batteries.  How did you disconnect the battery?
    This behavior sounds like a failure or fault in the batttery circuit and the only way to diagnose that is by taking the MBP to an Apple store genius bar or Apple authorized service center to have the techs run their tests.

  • Macbook pro will not save what I was working on when in sleep mode

    Everytime my computer goes into sleep mode or battery dies, it does not remember what I was last working on. It starts all over again

  • My MacBook Pro will not start. When I started it goes to a gray screen with the Apple logo and has the spinning dial. When I started in safe mode it will not start. In safe mode it as an error message that says MacBook Launch_msg():Socket is not connected

    If running 10.7 or later hold down Command-R at Startup.
    This should invoke recovery Mode.
    Choose Disk Utility.
    Select your Hard drive. Inspect the SMART Status in the lower right of the window for "Verified".
    Select the Mac OS X Volume (originally Macintosh HD) click (Repair Disk)
    If errors, run again until it comes clean or gets stuck.
    Report any error messages.

  • My MacBook Pro will not start up after entering correct password.

    My MacBook Pro will not start up after entering password.  Circle with an X in it and 'cancel' below it is on bottom of screen.  When clicking on cancel, nothing happens.  This just started last night.  

    Hi MJTOOTS,
    Since you are getting to the login screen, it is booting past the "gray screen" phase, so try the steps in this article, like a Safe Boot.

    Actually it sometimes gets a little further, the display will dim and the pointer will appear and then whoop it will turn off. if i do a verbose start up, it will finish all the steps, the white screen will appear and dim and then it will turn off.

  • MacBook pro, will not start up- drive begins

    MacBook pro, will not start up- drive begins?

    OK, then try this:
    Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    Since you can boot into safe mode successfully, I'm assuming the problem may be with a bad third-party extension or plug-in (such as a driver for third-party hardware or a bad Flash plug-in, for example.) It can also be a problem with a bad cache or preference file. If the above doesn't help then use a utility like Lion Cache Cleaner 6.0.5, Cocktail, TinkerTool Sys..., or OnyX to clean out user, system, and font caches.

    My macbook pro will not start up or turn on.  Any suggestions?

    I had the same issue I bought my MacBook Pro in Jan. my harddrive was bad and they had to replace it. I know the guy held down the shift botton for a little then pressed the power botton while still holding down the shift botton and it turned on but not completely since my hard drive was bad.

  • I am traveling and cannot connect my bluetooth keyboard to my MacBook Pro where I am. It was working fine when I left home. What can I do to fix the problem?

    I am traveling and cannot connect my bluetooth keyboard to my MacBook Pro where I am. It was working fine when I left home. What can I do to fix the problem?

    If you can get them paired again try making them "favorites" from the Bluetooth system preferences.
    Try smc and pram reset too.  May gave to do this before you can get them paired.

  • HT1379 My Macbook Pro will not start at all. I automatically get the Apple Icon and a pinwheel that keeps clocking. How do I fix?

    If anyone can assist with why my Macbook Pro will not pass the first screen, please respond. I have been getting the spinning pinwheel for a few days and cannot lg on now. In recent days I deleted some files and thought that would help the computer move a little faster but now it will not sllow me to access my account. Any suggestions on how to get pass the initial screen?

    Could be many things, we should start with this...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
    If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
    If 10.7.0 or later...
    Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
    If that doesn't help Reinstall the OS.

  • My MacBook Pro will not start up, any suggestions?

    My MacBook Pro will not boot up. I was aware of something odd when I switched it off a couple of hours ago  now when I push the 'on' switch something starts - fans I think, and the little indicator light on the front. Does anyone have any suggestions on how to solve this problem?
