# 拯救者R9000P设置电池充电阈值

## 脚本
```bash
#!/usr/bin/bash

if [[ "$1" == "on" ]]; then
    sudo bash -c "echo 1 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode"
    echo "充电阈值已经设为60%"
elif [[ "$1" == "off" ]]; then
    sudo bash -c "echo 0 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode"
