SYSTEM DOES NOT POWER-UP

Step 2. Remove bottom panel, and lay the system down on its left (monitor) side. Refer to Chapter 8, Remove and Replace Procedures.

Step 3. Reconnect the power line input cord to the system and

Press the 373XXA Power key on.

Step 4. Using a DMM or an oscilloscope, measure the DC power supply voltages listed in Table 5-1. Connect the DMM/oscilloscope to the top of the cable connectors at J13 and J4 on the Motherboard (A17). Refer to Figure 5-1and Table 5-1.
