きっかけ

電源接続中なのにバッテリーが減る場合があるので，まず状態を確認したい．
減る場合っていうのはこれ↓

コマンド

PowerShellでコマンドを実行する．

WMIC Path Win32_Battery Get BatteryStatus /Format:List

表示結果

結果はこんな感じ

BatteryStatus=2

で，何？

数字だけ出されても意味わかんないよ～

BatteryStatus

Data type: uint16

Access type: Read-only

Qualifiers: MappingStrings ("MIF.DMTF|Portable Battery|002.14")

Status of the battery. The value 10 (Undefined) is not valid in the CIM schema because in DMI it represents that no battery is installed. In this case, the object should not be instantiated.

This property is inherited from CIM_Battery.

Other (1)

The battery is discharging.

Unknown (2)

The system has access to AC so no battery is being discharged. However, the battery is not necessarily charging.

Fully Charged (3)

Low (4)

Critical (5)

Charging (6)

Charging and High (7)

Charging and Low (8)

Charging and Critical (9)

Undefined (10)

Partially Charged (11)

つまり？

BatteryStatusが
1：バッテリー駆動
2：AC駆動

実際の現象に対して

電源繋いでるのにバッテリー減る問題がまだ発生していないので，全く活かされていない
❗要検証❗
