Ok so this seemed like a simple U8900 issue fix, and after touching it up two days ago, the issue of it crashing on boot went away and for an entire day, the Mac was working fine would boot normal then shutdown normal no issue at all. NOW, it's not good. The battery, for one, says service battery, but that is not the issue as it does this even with no battery installed. What it seems to constantly do is boot about 60%, crash give me the error saying it restarted because of a problem message, hit a key try to boot, CRASH at the same point give SAME message, then on the third try boot and work fine. I have touched up U8900 again just to be safe and the joints are perfect, but the issue persists. I also noticed that if the computer hangs or pinwheels, closing the lid does not put the Mac to sleep as in the backlight and image stay on. The only thing I have not tried yet is a known good SSD. Could this be as simple as an OS problem/SSD problem? SSD is not full has 60 GB's free, but it is on 10.13.4 the newest OS. I'm definitely going to try another drive to rule it out, but I'm officially stumped on this one.
History btw: just started doing this out of the blue NO liquid damage period like very very clean and no drop damage that I can visibly see.
