I replaced the battery drivers in "device manager", updated power manager, made sure the "Conservation Mode" was "Off". Nothing changes. It still says battery is plugged in but not charging. If I remove from the outlet, the battery drains, but when plugged back in, the level remains where it was and still says "not charging". Some have said this might be a built-in method to help preserve the life of the battery, but there's usually an option in a "power" or "energy" manager to disable this feature. In Lenovo, it was the "Conservation Mode", but in my laptop, that setting is shut off. Is my battery dying? I bought the computer, brand new, less than a week ago.
Added (1). It's one of those built-in, difficult to access batteries, so I can't really disconnect it.
