After the computer has been active for several months, the battery may reach a critical charge level and cannot be charged. This is a battery safety feature.
Most HP business notebooks use transfer mode to reduce battery consumption. The transfer mode allows the battery to remain active longer than the computer remains off. However, the transfer mode is excited when the computer is first turned on. If you are not going to use your computer for a long time, such as during school holidays or for commercial purposes, put your computer in transport mode and then set it aside.
Note: Not all business notebooks support transfer mode. Please refer to the User Guide to determine if your computer supports this feature.
Before activating the battery transfer mode, follow these steps:
Update your computer's BIOS to the latest version. For more information, see Updating the BIOS.
Make sure the battery is charged to 80-90% capacity.
Select the appropriate method listed below to enable battery transfer mode.
Set the transfer mode by turning off the computer with a series of buttons
Set the transfer mode in the BIOS (F10)
Set the transfer mode using the BIOS Configuration Utility (BCU)
To exit the normal use transfer mode, connect your computer to the power source and press the power button to start the computer.
Note: If you do not use your computer for an extended period of time, HP recommends that you check your computer every 3 months to check the battery level. If the battery charge is less than 50%, recharge it to 80-90% and repeat the above steps to re-enter the computer into transport mode.
