State of charge issue - Dell laptop

[harm_less]

It was ticked and pretty sure I haven't done that purposely recently. Now unticked so hopefully issue resolved. TIA

it's the sort of thing that could have happened with a firefox update, someone probably thought it was a good idea for privacy reasons, or they didn't want to be sued for leaving you auto signins active, so explicitly force you to disable it, which I would guarantee is recorded in some log file or DB somewhere...

Don't know who you are implying by "someone". It is my own laptop and I'm literally the only person who touches it. The most significant activity done recently was the update to W11, and possibly the periodic FF updates that keep turning up. 

If W11 has fucked with settings like this then the battery management system may be their doing as well. MS has a long history of every second version being a dog and I'm erring towards W11 potentially being one of their barky ones.
