My daughter has white macbook (13", still has Leopard 10.5.8, though I've been planning to FINALLY upgrade it with the Snow Leopard disk that came with it), which is always used with the power adapter (and I've had to replace those magsafe ends 2x already, and now again). Gives it good use, though that stupid white plastic is breaking in several places. But it's working just fine, and I try mighty hard to keep it clean, up to date, backed up, etc. Yes, the bottom gets a bit hot sometimes, but no more than my 2009 15" Macbook Pro (metal, has 10.6.8, running fine). But her fan runs and all is OK. Till last week, once. Doing nothing important (streaming movies or some teenage crap) and it just suddenly turned off.  Power indicator shows full battery power, and shows when the adapter is plugged in, and charging -- and when the current magsafe end started failing and it went to battery power, which is just about when the second abrubt shut-down occurred almost a week later. Maybe the DC mag tip was crapping out the first time when it shut down last week also and I just noticed now. Seems fine in between and it's taken over 3 years for this to happen. Then it turns on again, no problem.

I've seen a number of simple, benign suggestions, but before I go ahead with them, just thought someone out there might have yet another -- or the best suggestion. Obviously I must do something, but am not really all that well versed in some of this stuff (the controller). Downloaded the SMC firmware update v1.1 but not put it into hers yet.

Any suggestions on where to start?

Thanks!

MacBook, Mac OS X (10.5.8)

    Hi , and a warm welcome to the forums!

     

    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.

     

     

    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...

     

    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive

     

    Reboot, test again.

     

    If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.

     

    Check the System Preferences>Other Row, for 3rd party Pref Panes.

     

    Also look in these if they exist, some are invisible...
