Hi everyone, I have heard about this website for many years, but that's my first post.
I got a MacBook Pro 15-inch 2013 (A1398), which I bought second-hand 4 years ago. I upgraded the SSD to a Samsung 970 Pro Plus after my purchase. It worked well until I upgraded it to Big Sur 2 years ago, and started to crash frequently. I tried to reinstall the system many times but not work, but it did get better sometime, so I am still using it.
On the other hand, the battery was getting fat, and I couldn't use the keyboard on a flat surface, so I replaced it with a third-party battery. During the process, I used isopropyl alcohol to remove the glue and maybe some drops on the mainboard.
Everything seems to be good for the first week until now:
1, it crashes more frequently, like every 3 mins
2, it won't boot sometime, like a black screen, then flash the file logo
I tried everything, including replugging the SSD and booting it without a battery. I can't fix it, but if it boots successfully, there is a chance to work well for a while, like allows me to type this post.
Any advice is appreciated.
