I have always had to plug this computer in to use it, and a screen has always come up saying the the charger isn’t great but if I want to continue I can click F1. Now, when that screen pops up I can’t click anything.
My guess is that either the charger is not working properly or the battery is overloading the charger or sending it a signal that it is bad. I think you should install a new battery if you can or have a computer repair shop do it.
