Battery management settings (Notebook PCs only)

After performing the Battery Test, HP PC Hardware Diagnostics might prompt you to change your battery management settings to optimize the health of your battery. The recommendation might vary depending on your computer model.

Battery Health Manager (Commercial Notebook PCs only)

If Battery Health Manager is supported by the BIOS, the Battery Test displays a prompt to change the battery setting, if the setting is not set to the optimal setting.

The Let HP Manage My Battery Charging setting dynamically changes how the notebook charges the battery based upon usage conditions and temperature over time, optimizing battery health over the life of the battery.

The Maximize My Battery Health setting limits the maximum charge level of the notebook battery to 80%, optimizing battery health over the life of the battery.

On the Battery Health Manager prompt, select either Main Menu to open the Main Menu and change the setting manually or select Change My Setting to automatically enable the recommended setting.
Select Accept.
Select Main Menu to return to the Main Menu.

The setting takes effect the next time the computer restarts.

If the automatic change fails, you can change the setting manually by restarting the computer and pressing f10 to open BIOS Setup Utility.

For more information, see HP Business Notebook PCs - HP Battery Health Manager.

Adaptive Battery Optimizer (Consumer Notebook PCs only)

Select HP Consumer Notebook PCs support Adaptive Battery Optimizer. HP recommends enabling this setting if it is disabled to help maximize the battery lifespan.

When Adaptive Battery Optimizer detects certain conditions, protective measures are activated to minimize premature battery wear. While it is activated, the battery run time might be slightly reduced.

On the Adaptive Battery Optimizer prompt, select either Main Menu to open the Main Menu and change the setting manually or select Change My Setting to automatically enable the recommended setting.
Select Accept.
Select Main Menu to return to the Main Menu.

The setting takes effect the next time the computer restarts.

If the automatic change fails, you can change the setting manually by restarting the computer and pressing f10 to open HP Computer Setup.

For more information, see HP Gaming Laptops - Introducing Adaptive Battery Optimizer, Designed to Prolong Battery Lifespan.

Battery Care Function (Consumer Notebook PCs only)

The Battery Care Function setting allows you to set the maximum charge level to either 100%, 80%, or 50%.

HP recommends changing this setting to 80% to help minimize premature battery wear and help provide optimal battery health over the life of the battery.

On the Battery Care Function prompt, select either Main Menu to open the Main Menu and change the setting manually or select Change My Setting to automatically enable the recommended setting.
Select Accept.
Select Main Menu to return to the Main Menu.

The setting takes effect the next time the computer restarts.

If the automatic change fails, you can change the setting manually by restarting the computer and pressing f10 to open HP Computer Setup.
