Since replacing it with the Redmi AX6000 last October, the Y1S that had served for nearly 10 years finally retired and has since been sitting unused in a box…

These laptops show continuous battery drain after shutdown, and in Windows 11 battery usage records the screen is shown as being on for nearly 24 hours during shutdown periods.
