   Thanks for reporting this. Can you tell us the laptop model and whether it is plugged in when it shuts down?

3. You3 days ago

   It is a ThinkPad T14. It shuts down on battery and when plugged in.

   We rolled back the update remotely. Please restart the laptop and tell us if it still happens.

   It shut down again this morning, twice, even after the rollback.

   Understood. We are running a hardware diagnostic. Please leave the laptop connected to the network today.

7. IT Supportyesterday

   The diagnostic shows a failing battery controller. This is a hardware fault, not the update.
