I bought a refurbished Dell chromebook, and used it for several months, taking it apart a few times. One day, I took it apart, and pulled the motherboard out, because I was curious if I could modify it, maybe change the ram, even though it's not meant to be changed. When I put it all back together, it wouldn't boot, not by opening the lid, not by pressing the key, nothing. I figured I shocked the board (since I neither own nor use any antistatic gear), and it was bricked. After a few months of sitting around, I tried ro turn it on again, just out of curiosity, and it booted like everything was normal.

Does anyone have any idea what could have happened?

Tldr: Chromebook I thought was bricked started like normal after months of sitting ¯\_ (ツ) _/¯
