Is adaptive brightness available for all Windows laptops?
Adaptive Brightness is not available for all Windows laptops. This feature works with an ambient light sensor, which detects light in the surroundings and adjusts the brightness accordingly. An ambient light sensor is generally found in high-end or 2-in-1 laptops.
Does keeping the laptop plugged in preserve battery health?
Keeping the laptop plugged in always does not necessarily preserve its battery health and can even lead to faster deterioration. A battery can go through only a finite number of charge and discharge cycles. Both Microsoft and Apple have advised against keeping the laptop always plugged in. For optimum battery health, keep it between 20-80% charged.
