[Solved] Dell T30 error: Alert! Cover was previously removed.

Dell T30 self-test is stuck in F1/F2/F5 option. If F1 needs to be started manually, it will be reported as alert! Cover was previously removed


1. Check whether the chassis cover is tight

2. Close the prompt in Bois

a. Clear the log (if the log is not cleared after the chassis cover is closed, the error will still exist because it still exists in the historical log)

b. The chassis intrusion is set to on silent

Chassis intrusion is used for chassis intrusion monitoring

Set disable to not detect; Enable is used to detect and record in post; On silent is detected but not displayed in post

In this way, there will be no alert after the power on again! Cover was previously removed
