You can either get a new motherboard and install it, or you can get the board repair and pay less. If the GPU's voltage drops along this voltage rail, it stops working, resulting in the kernel panic, and sudden restart. This results in the frame buffer voltage rail dropping in voltage every once in a while. One of the decoupling capacitors on this voltage rail is a poly-tanalum capacitor, which isn't very reliable when subjected to many heat cycles. There is a voltage rail that supplies the frame-buffer, which acts as a short-term memory bank for the graphics processor. Hey Jared, this is sadly a common problem with A1286 15" MacBook Pros from 2010 - I have an exact same MacBook Pro with the exact same problem :(Īnyway, the issue is most likely caused by a faulty capacitor on the motherboard. The character count and spam blocker of this website was quite the nuisance when trying to post and give adequate information about the problem I'm having. Thank you for your time and help in advance! I'm unfamiliar with the logic board issues. The temperature does not seem likely as the computer does not seem very warm via touch or when utilizing TG Pro or Coconut Battery. I've read several articles talking about overheating issues, logic board issues and other such problems, but not sure if these actually apply to my situation. ![]() I've never encountered this problem before, and not sure what action to take next. I have downloaded Coconut battery which gives the following stats: I have since reformatted the computer, and the problems persist. The computer recently started having problems approximately 2 months ago. I also replaced the original RAM 4 GB to 8 GB I replaced the hard drive with a Samsung 250 GB SSD last christmas. Graphics: NVIDIA GeForce GT 330M 256 MB.and then will allow me to put in my password and restart. The sequence of events that most often occurs is the computer will crash without warning. Provided as much as the crash report as possible. com.apple extensions were not permitted as they were pegged as spam. Some of the information above regarding the. ![]() What can I try to make this situation go away? It occurs more often when running off of just battery supply, even with the charge at full. The computer has a nasty habit that has developed out of the blue where it shuts down and restarts whether it is running off of power supply or battery supply. I just installed your app, and am at home, unable to test it fully.Need some assistance with my Macbook Pro 15'' Mid 2010. As far as I can tell, the app does permit power-source-based switching without the login display resolution problem! I have to test the effects on an external projector display next week when I'm in a classroom, however it may limit the resolution available to me when running on battery power and connecting a projector. This application allows me to choose the card to use when I want to save battery power and have no external display connected.īut it resets automatic switching if it was turned off before the app was run. This seems to be an Apple bug triggered by some update in the past couple of months, at least on my MBP. You can't get back the highest resolution and have black bars at the top and bottom of the screen (the higher resolution setting is not available on the integrated card, and for some reason the system won't permit the change). On some Macs with dual cards, such as my 2011 MBP, use of the Energy Saver automatic graphics switching will trigger a display problem when logging out and logging back in: the display will be stuck on a lower-resolution option until restart.
