“What then?”
“Same as it ever was!”
We all fight over resources that actually matter (like food, water, shelter and security) instead the previous things (money), for the enjoyment of our overlords.
Seriously, the people who have power to change the outcome of the future seem to either straight not be planning for this future scenario, or are planning for a horribly distopian version of this future scenario.
I don’t have a Lenovo, but a Dell Latitude that i use like a desktop, mostly plugged in next to my couch. In the bios you can set it to optimize the battery and charging for ‘primarily AC usage’, as well as set a percentage to limit charging, I think I have it set to 85%, I would assume you can do the same on a Lenovo.
I wouldn’t worry too much about it past that, if leaving it plugged in all the time is convenient, just do that. You could also probably buy a new battery on eBay and replace it if your battery is actually shot and you want better life.
