MacBook Pro A1278 starts, apple logo appears then shuts down
My wife has a MacBook Pro a 1278 model that will not boot up or turn on. I'm not certain of the exact version of 1278 but the serial number is: W80226HJATM
When I press the power button I hear the fans start to spin, the screen lights up gray, the Apple logo appears, the progress bar on the The bottom blinks twice while the time dial spins one revolution then the screen goes black and the computer turns off.
I have searched through the forums to find anything that is applies as the system does not hang in eternity,blink on and off or sit spinning -- it starts the boot sequence then just crashes. It has worked mostly fine for a long while, nothing spilled that i am aware of, battery seems good and the problem exists whether it's plugged in or on battery.
I tried command S to diagnose as seen in another post but honestly don't know enough about macs to see what is out of the ordinary as it seems to be a standard boot log. At the end it prompts me to type exit to continue the boot Which I did and the following lines appeared:
KEXT loading now disabled
KEXT unloading now disabled
KEXT autounloading now disabled
Kernel requests now disabled
Can't Get KEXTD port
Syncing disks… Killing all processes
Airport: link down on space. Space reason 8 (disassociated because station leaving)
I managed to take a photo of the previous results I just typed above (before it shut down again) but not certain if there may have been more lines just before it died.
I've read some mention of resetting the smc but can't find any details how to do that.
we will go to our storage locker this afternoon to retrieve the boot disks but not certain what to look for or do when we try to boot off of them.
Thanks for any and all assistance.
