This is a 2018 model system, so it's four years old. Was the battery replaced before you purchased it?  If not, the battery is likely showing its age and needs to be replaced.  
Hi every one. Recently I booght a Dell 7490 that is a very nice machine. I upgraded it to windows 11 and from then I am facing a terrible issue that my battery drains even if its shutdown. A couple of times I left it at 91% and turned it off but next time when I start it it only shows 10% battery. Thats horrible!! Can somebody suggest me a solution??
Battery drains unexpectedly even My Dell 7490 is shutdown.
