Hello Team!

Today, I've found out quite interesting bug happening on my setup. I'm connecting MacBook Pro M1 to Dell P2421DC via USB-C cable so Laptop dives display data and Display dives charging power to laptop. If I'm connecting my laptop with battery at the same or higher charge level than set up in AlDente, then connection to display breaks up immediately after closing laptop lid. Id I'm having battery at lever eg. 50 and set AlDente to charge the laptop to eg. 60%, everything works fine.
I've checked this both on Allow discharge mode on and off, in both scenarios it's acting the same way.

Hi @kijewskimateusz,

This is due to technical limitations while allow discharge is activated.
Are you sure it is also happening when allow discharge is disabled?
