MacBook Pro Frequently Beeps in Sleep Mode

When I put my MacBook Pro into sleep mode and close the lid it and come back later it beeps every so often (probably about every 30s-1 minute): it seems to be the same sound as when the PSU is connected. This is really annoying (especially at night) and means I usually disconnect it from the PSU. When I go back a couple of days later it's seemingly run out of juice. Does anyone have fix(es) please?

Thanks in advance.

hmmm... why not plugin the PSU only when you are using it(?)


Frequent issues caused by using an incorrect wattage charger, a faulty USB-C/MagSafe hub, or a failing logic board power rail; try different port, different cable, different PSU


Contact the PSU vendor for support...
