My Macbook pro (bought in August 2009) has shut down twice today, each time after the computer being on for about 15 minutes. The battery is not dead and the computer isn't overheated because it was only on for a few minutes prior. The machine seems to stop completely, but then returns to the screen I was on before it shut off. Any ideas?


P.S. I just downloaded OS X Snow Leopard last week, so I'm not sure if that is playing a factor.

MacBook Pro, Mac OS X (10.6.8)

    That is not any proof regarding the health of your battery.


    You need to go to the Apple Menu, About This Mac, and in the window that pops up click More Info... In the next window that comes up click System Report... Then click on the Power category and take a screen shot and paste it here so we can see about the health of your battery.


    It will look similar to this:

    Did you buy the Snow Leopard disc from Apple or did you get it via a torrent site or something similar? Just asking because Snow Leopard is not available as a download from Apple. If you downloaded it via a pirate site, I would suggest buying the 'real' disc and using it. I would also recommend restoring from an old backup if you used a pirated version of Snow Leopard. Pirated software - especially OS X - is notorious for being loaded with malware, etc.

    I bought Snow Leopard from the Apple Store online and had them ship it to my house. I didn't trust downloading it from any other site.


    Reason is because I got an iPhone 5 and wasn't able to download the new iTunes to hook up my new iPhone without upgrading to Snow Leopard.

    You just had me worried with that "download" part - sorry.


    You can try a couple of things - but I doubt that they'll fix your problem. First reset your PRAM/NVRAM, then try resetting the SMC. No luck with either, insert the SL installation disc and use Disk Utility to both repair permissions and verify and, if needed, repair your hard drive.


    Beyond that, there's no much else I can suggest other than taking your machine into your local Apple Store or AASP and having them run diagnostics on the machine.


    Good luck,

    I had the same exact problem and after a week of searching all over the web for a solucion, I finally figured it out myself.


    Check if the "Automatic Graphic Switching" (System preferences<Energy Saver<Automatic Graphic Switching) is ticked. If it's not ticked it means that the computer uses the highest graphic settings at all times and it causes repeated kernel panics.


    So just tick it.


    If not- something else might be causing for the kernel panic. Try to remember if you did a certain change for the settings more or less at the time the shut downs began, and undo it.

    I'm having a "random shut down" with my macbook pro (2009) as well. I checked my Power usage in the "About this mac" and it is not fully charged and not charging, yet my charger is plugged in and the little green light is on. The battery status on my top menu bar says "(Not Charging)" as well.


    Just yesterday, the laptop wouldn't restart after a "random shut down" until I plugged it in. The battery looked charged when it restarted, but when I pulled the plug out, it shut down again, twice.


    Battery no good anymore?

    I know this thread is "closed" but I just wanted to add a point.  I recently have the same problem with my macbook pro (mid 2008/last one before converting to the unicase version).  The computer would work for about an hour before it just shuts down.  When I tried turning it on again, it refuses to stay on for the next ~15 minutes (grey screen, shut down).  When I let it rest for a little bit, it would turn on and usable for ~hour. I did everything (reset smc, nvram, the works) but nothing helps.  Finally, I found a relatively obsure thread from a guy with similiar problem.  He fixed it by replacing the thermal paste on the heatsink/cpu/gpu.  I did the same thing (instructions on  and my computer is now working again.  Anyway, FYI.  Good Luck!

  • erickaujero Level 1 Level 1 (0 points)

    Yep, i agree with Ustilago.  my sister's Mid 2009 Macbook pro had the same problem. it was out of warranty so i did a little DIY stuff. after reinstalling the OS, checking RAM. the problem persisted. the battery was for replacement so i thought it was the battery but when i removed the battery and powered the MBP, it still shut down randomly. so i thought of the last thing( since it was kinda old MBP) i checked the thermal paste for both the video card and processor, they were baked(or dried and chalky). so i cleaned it up and put in new thermal paste and the MBP is fine and working without the random shut down thing.
