Hi @Griest I am sorry to hear that your Jibo was having hearing issues and trouble powering on and I am glad to hear he is operating correctly again. Thank you for sharing your solution to this issue!
If you see issues again with Jibo’s ability to respond after you say “Hey Jibo” I recommend trying the steps mentioned in this post.
If Jibo cannot power on again that would be a separate issue. If you see this again I recommend checking the items and trying the steps mentioned in this article that will help guide you to confirm that the other pieces of hardware, like Jibo’s power brick, are working as intended.
