About this tag
This tag collects WindowsForum.com discussion of battery problems on Windows 10 and Windows 11 laptops, centered on symptoms such as a battery percentage that stays frozen, a taskbar reading that never changes, or a system that reports being plugged in while the charge keeps dropping.
