### Battery Conservation Mode

Lenovo laptops come with a battery controller setting called "Battery Conservation Mode", which shifts the usual loading thresholds from 95/100% to 55/60% to reduce battery degradation. To enable this, install the acpi_call package. The mode is enabled with:

    # echo '\_SB.PCI0.LPCB.EC0.VPC0.SBMC 3' | tee /proc/acpi/call

It can be disable with:

    # echo '\_SB.PCI0.LPCB.EC0.VPC0.SBMC 5' | tee /proc/acpi/call
