I run boinc 5.10.45 on gentoo, I've set in the preferences that the program will not compute while on battery, but when I unplug my AC adapter, boinc continues to calculate.

is this a bug? in previous versions I didnt had this problem

It might be a bug but first check what you have selected on the Activity menu. If you have Run always selected then your preferences will be ignored. If you have Run based on preferences then it should suspend.

already thought that way, it is set to Run based on preferences

If you didn't use local preferences, did you "update" the (correct) project to allow reading the preferences from the server?

Two more ideas (guesses actually, since I'm no expert):

How long does BOINC continue to calculate after unplugging? Perhaps only until the next checkpoint is reached, as you don't leave applications in memory?

Perhaps linux doesn't "tell" BOINC (any longer, new version?) that the computer is running on batteries.

previously the action took place immediately.
I had an issue that the system didn´t noticed that the adapter was disconnected but I've fixed it

boinc haven't calculated my signature yet, but it is on the WU schedule.

just to make it clear, the issue haven't been resolved
