Had the Jetbot working the night before. When I woke up, the fan and PiOLED were not working. I tried rebooting, with no luck, so I tried a new (different) SD card, with no luck. The unit EVENTUALLY gets to a desktop, but the KB and mouse don’t respond at all and the fan and PiOLED won’t run
I unplugged everything that was unpluggable, IE system board, jumpers, fan, WiFi card, anything plugged into UISB, and blew it off, thinking that something might have fall into it to short something, but, I’m still getting no response from it
It shouldn’t have had a power issue, because it was plugged into an APC UPS, and the APC is reporting no issues
I’m kind of at a loss as to what I can do to recover the unit
Is there a (preferably simple) known fix for this kind of issue ?
