カバーを閉じた後にノートパソコンのキーボードがロックされる

Dell Latitude 5500とDell Latitude 7550があります。 5500にはDebian 10とKDEがあり、7550にはKDEとUbuntu 20.04があります。両方のノートブックがふたを閉じて後で開くと、内蔵ノートブックキーボードが完全にロックされて何も入力できません。ただし、トラックパッドはまだ機能しており、[ユーザー切り替え]をクリックできます。これを実行して再度ログインするように求められたら、ノートブックキーボードは両方のノートブックで再び動作を開始します。

これが問題かどうかはわかりませんが、ラップトップに外部10ポートUSBハブが接続されています。外部キーボードとマウスを接続しました。外部キーボードもロックされますが、外部マウスも機能します。

ノートブックカバーを閉じるとキーボードがロックされるのはなぜですか？この問題を解決するために私ができることはありますか？
