Hi @fabianhugo
Could you provide exact steps to reproduce?

If the reset button is pressed around 5 seconds (you can see the red LED dimming out), the board is meant to go into a "deep sleep" mode, and in that mode the power red LED will turn off. Is that what you meant? Or does it turn off in a different situation?

Hi @microbit-carlos,
thanks for your fast reply :)
Yes, i was also wondering if it has something to do with the deep sleep mode, but the main program keeps running and I am pressing the reset button just very briefly. In programs where the display is used this is not a real problem, but it can be, when the display remains off.
I checked the interface firmware in DAPLink version v0257 and the problem is not there. Below I attached two videos with a micro:bit v2.20. The program on the micro:bit is a standard makecode program:https://makecode.microbit.org/_95gfJ5TskDvb
