Treat Never as a temporary comparison of the active power plan’s sleep timeout, not a required permanent power policy. Record the old AC/battery values.

  • Immediately after upgrading, the PC repeatedly slept every 15–20 seconds and returned to the PIN screen.
  1. Open Power Options and the active plan settings.
  2. Set Put the computer to sleep to Never.
  3. Apply the setting.
  4. Use the PC and restart it to verify the repeated sleep no longer occurs.

Reported outcome: The topic starter repeatedly verified the system stable with sleep set to Never, and a second same-model reporter said the setting solved the reset/sleep problem.

After the comparison, choose the intended sleep timeout and verify that the premature sleep does not return. Restore the recorded settings if the test has no effect.
