Downloaded the latest firmware and put it on the card. Inserted it with the battery and turned the P3 on. Went to walk away to let it do its stuff. Noticed white smoke coming from the off side vent so grabbed the P3 and pulled the battery. Theres also a strong smell of burning plastic. After inspecting I seen that one of the cables leading to the camera had melted. No sure if there's any damage inside but glad I never just walked out the room. It's just had a new camera fitted no long back.
