I have a Pi 3 Model B Rev 1.2 which has been running fine for 2 months. It was accidentally knocked off its shelf yesterday (about 1foot drop) It booted back up fine, but now it only stays on for 20 minutes before abruptly disconnecting. The red power light is on steady, but ethernet is off, and it seems all other power is off.
Is a 1 foot drop (plastic case) enough to damage the hardware? Is there a process I can implement to help me figure out if this is a hardware error within the 20 minutes it stays accessible?
I have Debian 10 installed on the system.
