Symptoms
Dell Precisions will Shut Down or Not Power on Without the Side Cover
The Dell Precision 5820, 7820, 7920 Tower and XL Tower systems need the side cover on the system in order to operate. If the side cover is removed while the system is running, the system will immediately (within 4 seconds) power down. If the side cover is off when powered on, a Power Button LED error code of 4-7 appears.
Cause
The system is designed that it requires the side cover to be in place for proper operation and for safety considerations.
Resolution
This behavior is normal and is working as designed.
