Run the advanced diagnostic test for the system board in loop mode at least 10 times. 2. If no error is detected, do not replace any FRU. 3.
Motherboard CMOS Discharge If any problems such as incorrect CMOS settings, the CMOS data can be cleared by short-circuiting the CMOS J6 jumpers. Open the 3G bay door and short-circuit the jumpers near the 3G connector, using a metal conductivity tool.
