Chapter 5 Troubleshooting the System Hardware

Checking the Power Subsystem

Note If diagnostic error messages appear that are not listed in the tables, make sure that your device has the latest levels of BIOS and diagnostics microcode installed.

Checking the Power Subsystem

Power problems can be difficult to solve. For example, a short circuit can exist anywhere on any of the power distribution buses. Usually a short circuit will cause the power subsystem to shut down because of an overcurrent condition.

To perform a general procedure for troubleshooting power problems, follow these steps:

Step 1 Power down the device and disconnect all AC power cords.

Step 2 Check for loose cables in the power subsystem. Also check for short circuits, for example, if there is a loose screw causing a short circuit on a circuit board.

Step 3 Remove adapters and disconnect the cables and power connectors to all internal and external devices until the device is at the minimum configuration required to start it.

Step 4 Reconnect all AC power cords and power up the device. If the device starts up successfully, replace adapters and devices one at a time until the problem is isolated. If the device does not start up from the minimal configuration, replace components of a minimal configuration one at a time until the problem is isolated.

To use this method, it is important to know the minimum configuration required for a system to start.
