Hi @yaciinne7,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

I understand you’re asking about the Power Management / Power Control options in the BIOS and what they actually do. Let’s go through the common power management settings you’ll see in HP BIOS and how they affect your system.

Battery Health Manager / Adaptive Battery Optimizer
This controls how the battery is charged to reduce long-term wear.
When enabled, the system may stop charging at ~80–90% depending on usage patterns.

Maximum Battery Capacity
This option intentionally limits the maximum charge level.
It helps extend battery lifespan but will reduce total runtime per charge.

Fast Boot / Power-On Behavior
This determines how much hardware initialization happens at startup.
Disabling Fast Boot can improve hardware detection but slightly increases boot time.

Power Control (Sleep, Hibernate, Shutdown behavior)
These settings define how the laptop enters low-power states.
They control energy usage when the system is idle or the lid is closed.

Wake on AC / Wake on USB
Allows the system to power on or wake when AC power or a USB device is connected.
Useful in docking or office setups but can cause unexpected wake-ups.

Fan always on while AC
Keeps the cooling fan running when plugged in.
Helps with thermals but may increase noise and power consumption.

USB Power in Sleep / Always On USB
Provides power to USB ports while the system is sleeping or off.
Convenient for charging devices but increases standby power drain.

Thermal Profile (if available)
Balances performance, noise, and power usage.
Higher performance modes consume more power and generate more heat.

I hope this helps.
