Hi I have this problem with my xbox series s when completely shut down I hear noise on the left side of series s which power supply unit located,is this normal or any fix for this.
Reza Rad not sure what noise you hear but it is not uncommon to have a humming or even faint whining coming from a PSU. If your Xbox functions as it should, leave well enough alone. If it does not, then give us more information.
