It looks like you are stuck in S3 suspend/resume mode. If you are, you need to remove power completely, including the RTC battery if mounted. Wait for 10 seconds or so and then apply power. If only one LED is active now, hold the power button in for 5 seconds or more. Then release and press it again and see if that solves the problem.

Best regards,
