      Guide Steps

      Step 1 — オリジナルBMSデータ記録

      このバッテリーは再キャリブレーションした時の結果と程遠い状態にあります。

      Step 2 — ラップトップを使用

      復元できないデータを使った作業はしないでください。 このデータを失ってしまうことになります。 ラップトップを接続するだけで、BIOSロックアウトから起動できます。

      Step 3 — ラップトップをプラグイン

      ラップトップを使用しても安全ですが、キャリブレーションの精度に影響を与えてしまうことがあります。

      Step 4 — キャリブレーション結果の検証

      この手順によって、寿命に近いバッテリーが損傷する場合があります。

      Step 5 — バッテリーヘルスチェック(Windows 10)

      容量が不安定な場合は、バッテリーを交換してください。

      Step 6 — (UEFI BIOS) HP 15%ロックアウトのバイパス

      この作業をすることで、バッテリーが完全に放電できます。 HPの診断では、バッテリーの充電はチェックされません。

      Step 7 — (Legacy BIOS) HP 15%ロックアウトのバイパス

      これらの設定をメインOSに適用しないでください。 バッテリーを損傷する可能性があります。

      Step 8 — (Error 0190) Lenovo 重大な低容量バッテリーのバイパス

      電源アダプタをラップトップに差し込みます。 システムを起動するには、POSTを終了する必要があります。

      Step 9
