As for PJ, the battery thing works for me many times. Battery out, un plug, hold the ON button, and plug it back in. Should work with no restore needed.
My old Acer 5515 does this frequently.
Macs are incredibly stable and reliable, and their service is excellent. You get what you pay for. What’s with the “doorstop” meme? Sounds like you haven’t owned a Mac since the 80s.
