Ubuntu 20.04-過熱後のシャットダウン
Thinkpad L13を使用しています。今、私は特に全負荷の下で熱問題を抱えています。すべてのコアを利用するPythonプログラムを実行すると、ラップトップがすぐにシャットダウンします。
これまでに何を試しましたか？マシンにTLPとThermaldをインストールしました。さらに、BIOSのIntel設定を「バランス」に変更しました。
最近、2つのことが行われました。
Ubuntu 20.04をインストールしました。
ThinkPadのグラフィックの問題により、最近メインボードが変更されました。多分それはクーラーが適切に合わないようなハードウェアの問題ですか？
それ以前は問題ありませんでした。
この場合、コマンドgrep -i -e temp -e therm /var/log/syslog*は次の出力を生成します。

今日、私はズーム会議をしました、そしてラップトップは会議中にそれがオフになるように熱くなりました。これは起こるべきことではないですよね？ここで何が起こっているのですか？ここでは複雑な計算はしていません。多分それは私がそれを入れて以来、電源と関係があるのでしょうか？

私はパフォーマンス設定を最大レベルに設定し、ノートブックのさまざまな温度レビューで行われるのと同じストレステストを検討しました。 Windowsでは、私はそれらと同じような値を取得します。そのため、新しいUbuntu 20.04ではmustが問題になると思います。どういうわけか、Ubuntuは温度が下がるような周波数を抑制しません。
あなたの場合、ハードウェア+ソフトウェアシステムの完全な診断をaskubuntuで実行するのは困難です。ハードウェアの問題は特に困難です。
診断の最初のステップの代替手段として、Ubuntu 20.04と一緒に別のOSをインストールし、集中的なテストを実行することもできます。
同じPythonプログラムを実行することができます（すべてのコアを使用するように構成できる場合）。それでも、シャットダウンとまったく同じ条件で実行されない可能性があります。パフォーマンスをテストするためのアプリケーションであり、十分に優れている（またはプログラムよりも厳しい）必要があります。また、考えられるUbuntu 20.04構成による「汚染」はありません。
その後、完全な診断が終了したら、このOSを削除して、Ubuntuのスペースを再利用できます。
