私のopenSUSE 15.2ノートブックは、過去4週間に3回予期しないシャットダウンを経験しました。予期しないシャットダウンとは、突然の停電のように、システムが意図せずに突然シャットダウンすることを意味します。それぞれの場合、バッテリーは少なくとも70％充電されていたか（現在のように）ラップトップがドッキングステーションに接続されていました。 （システムがリリースされてから6ヶ月も経っていません。）
このような中断が発生した場合、システムは重いタスクを実行せず、RAM（32 GB）がまだいっぱいになっていません。 jEdit）、Dolphin（KDEの下）、そして（最後は今日ではありません）、LibreOfficeとTerminatorもありました。私は通常VeraCryptを実行していますが、今日は電源が切れたときに実行されませんでした。つまり、実行中のアプリケーションに基づいて電源が切れる現象を説明できません。
今日は、、、、var/logなどのログファイル（今日変更されたログファイル）を見て、のダンプも調べてみましたが、何を探すべきかわかりません。lastlogwtmpsnapper.logwarnmessagessudo journalctl --since today > /home/.../journalctldump
var/log/warn電源を切ると、次のような行が見つかりました。

複数行には、「不可能」、「失敗」、または「致命的」などの文字列が含まれていますが、そのうち突然のシャットダウンを引き起こす可能性があるものを指しているものがあるかどうかはわかりません。ログファイルを調べて、これらの停電の原因を見つけることができますか？それともこれは絶望的な仕事ですか？
