ThinkPad X260のBIOSをアップデート
しばらくぶりにLenovo Vantageを起動してアップデート関連をチェックしました。手持ちのThinkPad X260のBIOSを1.23 (R02ET50W) から1.40 (R02ET67W) へアップデートしました。

Lenovo Vantageという純正のシステム更新ツールを起動します。

Lenovo Vantage

Lenovo VantageによるとこのThinkPadには 推奨2件、オプション2件のアップデートモジュールがあるとの結果が出ました。

Lenovo Vantage システム更新

仕事が忙しく平日はなかなかPCを止める時間を取れないので他のアップデートモジュールも推奨とオプションレベルのものも含め、まとめてダウンロードしして、インストール適用することにしました。
考え方によっては、使えていれば新たなトラブルが起きる可能性のあるアップデート作業自体を回避するということもあるでしょうが、私はバグフィックスでの向上が見込める場合はなるべく適用するようにしています。


BIOS更新

今回は Update ThinkPad BIOSを選択して Next です。

アップデート中は電源OFFしないようにとの警告メッセージには Yes を選択して、いよいよ更新を適用します。


BIOS更新

コマンドラインでのBIOS書き込みが行われた後、システムの再起動が必須なのでメッセージに従って処理を進めていきます。

Windowsが立ち上がったら改めてLenovo Vantageを起動します。

Lenovo VantageでBIOS 1.40を確認

ThinkPad X260のBIOSがバージョン1.40へアップデートされていることを確認しました。

システムの設定値も維持されていて、特に問題なくアップデート作業ができました。




以下、今回のバージョンまでのBIOSの更新履歴・内容です。
