Why is my 2010 MacBook Pro shutting off at startup
I have an mid 2010 MacBook Pro 13" that shuts off during, or immediately after, startup. Normal startup doesn't make it through the startup screen. Safe boot or Recovery gets me beyond the startup screen, but within seconds it shuts off. In either case, the screen gets dark (not totally black, just loses about half the light) about halfway through the startup screen.
I have reset the SMC and PRAM. Didn't work. A different hard drive didn't work. Placing the drive in an enclosure and connecting via USB didn't work. Swapping out the battery didn't work.
I can't keep it running long enough to run diagnostics.
Any thoughts? Am I looking at a faulty logic board?
Es esta una buena pregunta?
