Handling Process

l   Radical solution: Replace the display or USB device that has electric leakage.

l   Workarounds: Unplug the cable of the VGA or USB device before you power on the T3500, and re-plug the cable after you power on the T3500.

Root Cause
If the VGA or USB device has electric leakage before the T3500 is powered on, the internal protection mechanism of the T3500 protects the T3500 from being powered on.
