今日はコンピュータの電源を入れましたが、起動ワークフロー中に電源が数回切れました。
ログを確認しましたが、理由が見つかりませんでした。 14:00頃に電源を入れました（成功的に起動するのに何回かかりました）。
予期しない停電は、システムのロード後、GRUBメニューが画面に表示された後、パスワードの入力後、X-Window Managerのロード後、以前のブラウザセッションが再開された後、または新しいインターネットページが起動したときなど、さまざまな時点で発生します。開き始めます。
それから今まで仕事をすることになりました。
以下のリストには、14:13 ブート後数行、14:19 新しいブート前の数行が表示されており、外部停電が発生する約 6 分前に動作していたため、おそらく原因を要約できます。次のエラーメッセージが見つかりません。
：コンピュータの電源が…理由またはその他の理由でオフになっています。
manjournalctlを読みましたが、わかりません。どのトピックを探すべきですか？
予期しない停電の正確な原因を見つける方法は？
以下に、今日の最初の電源投入時のログを示します。これには、開始から通常のワークフローまでのすべての短い時間が含まれています。
