Mintypi 3, no power from battery, okay from USB
Posted: Thu Oct 31, 2019 3:28 pm
I hate to be That Guy but I don't know what else to try here... this is my second MintyPi 3, first one went together with no issues. Everything is working on this one (screen, sound, buttons) but it won't power on when connected to the power board (power via USB is fine). Things I've tried so far:
* Went through the sticky thread: viewtopic.php?f=34&t=7951
* 5V continuity to test pad and D1
* Made sure there's no continuity between any two pins on the Pi itself, other than the 5V pins
* Voltage tested the battery (currently 4.15V)
* Hard-wired 5V and GND on the test pads to the pads on the Pi to be sure I have a good connection
* Continuity tested the actual power switch itself
* Continuity tested all the pins on the little power board cable
* Checked that the sockets for the power board cable are not bent
* Checked voltages described here: https://cdn.discordapp.com/attachments/ ... latges.jpg
Here's the current state of the bottom of the board: Any other ideas on what I can check? Thanks for any help! Sorry to bug you @helder, I bet you're sick of customer support on this thing. haha
