# 배터리 충전 모니터 설명서

## 소개

### 배터리 충전 모니터 애플릿

배터리 충전 모니터 애플릿입니다.

배터리 충전 모니터는 노트북 컴퓨터의 배터리 상태를 보여줍니다. 모니터는 남은 용량을 시각적으로나 백분율로 나타낼 수 있을 뿐만 아니라 현재 사용률을 기준으로 남은 시간을 추정할 수 있습니다.

### 패널에 배터리 충전 모니터를 추가하려면

패널에 배터리 충전 모니터를 추가하려면 다음 단계를 수행하십시오:

1. Right-click on the panel.

2. Choose Add to Panel.

3. Scroll down the list of items in the Add to Panel dialog, then select Battery Charge Monitor.

4. Click Add.

배터리 충전 모니터 애플릿의 레이아웃은 애플릿이 있는 패널의 크기 및 유형에 따라 달라집니다.

### Power Management Backends

The battery monitor supports a number of power management backends. If it is available, the monitor will attempt to use the freedesktop.org upower interface. If it is unavailable or unsupported on your platform, it will fall back to the freedesktop.org HAL (Hardware Abstraction Layer). If that is also not available, the battery monitor will attempt direct access to the power management system

Not all power management backends are available from all vendors, and some vendors add their own additional backends for specific platforms and hardware. If the battery monitor is misreporting information from your battery see battstat-troubleshooting.

### Getting Help

If the battery monitor doesn't work for you, see these additional resources:

- battstat-troubleshooting;

- MATE mailing lists

## 기본 설정

To bring up the preferences for the monitor, right-click on the monitor in the panel and then choose Preferences

### 배터리 충전 모니터 컨텍스트(우클릭) 메뉴

Appearance

- Compact view

- This view shows only a single graphic in the panel, either an upright battery to indicate remaining capacity or a plug to indicate your laptop is connected to an external power source.

  ### Compact view

  Compact View

  The compact view is the default view for the monitor as of MATE 2.12.

Expanded view

- The expanded view is old look from previous versions of MATE. It has the larger graphic for the battery as well as a separate graphic to indicate what state the battery is in.

  ### Expanded view

  Expanded View

Show time/percentage

- Selecting this option will display one of two pieces of information. Show time remaining will tell you how many hours and minutes until the battery is fully discharged or recharged. Show percentage remaining will tell you the percentage charge remaining in the battery.

Notifications

- - Warn when battery charge drops to

    Selecting this option will cause a warning dialog to be displayed whenever your laptop battery reaches specified value, either as a percentage remaining or a number of minutes remaining. This indicates that the amount of charge remaining in your battery is critically low. charge. You can dismiss this warning dialog yourself, otherwise it will vanish automatically when you plug your laptop into mains power.

  - Notify when the battery is fully recharged

    이 옵션을 선택하면 배터리가 완전히 충전되었을 때 알립니다. libnotify 지원을 사용하여 배터리 충전 모니터를 컴파일하면 패널의 모니터에서 비침해 알림이 팝업됩니다.

## Troubleshooting

Due to the complexities of power management and the vast differences between each of the different power management systems available, debugging errors in the battery monitor can be difficult. You will need to determine if the error exists in the battery monitor or is a bug in the information provided by your machine.

다음 정보는 배터리 모니터의 문제를 해결하는 데 유용할 수 있습니다. 그것은 결코 완전하지 않습니다. 배터리 충전 모니터에 버그가 있는 경우(ACPI에서 보고되는 잘못된 정보로 인한 것이 아님) 이를 보고하십시오.

### Determining the backend

If you are using the upower interface, or the Hardware Abstraction Layer (see battstat-power-backends) then that will be indicated in the about dialog by placing a star next to the author of the HAL backend.

#### Check you're using the HAL backend

Expanded View

Other backends do not currently give indication they are being used, so you will have to guess based on your hardware. Most modern PC laptops are using ACPI as the backend. This is also the backend with the largest number of inconsistencies.

### Checking the ACPI information

배터리 충전 모니터에 ACPI 백엔드를 사용하는 경우 ACPI가 올바른 정보를 제공하는지 확인하는 것이 중요합니다. 그렇지 않은 경우 DSDT 업그레이드나 ACPI와 관련된 다른 작업을 검토해야 합니다.

#### Example ACPI output

    [rupert@laptop ~]$ cat /proc/acpi/battery/BAT1/info
    present:                 yes
    design capacity:         41040 mWh
    last full capacity:      37044 mWh
    battery technology:      rechargeable
    design voltage:          10800 mV
    design capacity warning: 745 mWh
    design capacity low:     0 mWh
    capacity granularity 1:  10 mWh
    capacity granularity 2:  10 mWh
    model number:            G71C00056110
    serial number:           0000000008
    battery type:            Li-ION
    OEM info:
    [rupert@laptop ~]$ cat /proc/acpi/battery/BAT1/state
    present:                 yes
    capacity state:          ok
    charging state:          discharging
    present rate:            11232 mW
    remaining capacity:      27140 mWh
    present voltage:         11400 mV
    [rupert@laptop ~]$

You can quickly calculate the percentage remaining using remaining capacity divided by last full capacity, you can calculate the time remaining by taking remaining capacity divided by present rate.

### Hardware Abstraction Layer

You can check that your battery is detected by HAL using the command `hal-device-manager`. If your battery is not detected by HAL or the wrong information is being reported, you can attempt to disable the HAL backend by setting a GSettings key.

Select Configuration Editor from the Applications menu, under System Tools. Search for the key value `OAFIID:MATE_BattstatApplet` which should be located in the path `/apps/panel/applets`.

Assuming the path is `/apps/panel/applets/applet_1`. In `/apps/panel/applets/applet_1/prefs` add a New Key... called no_hal and set it to the boolean value of true. This will disable the usage of HAL (see battstat-troubleshooting-backends to learn how to check this).
