Dell OptiPlex - Solid amber light, lights 2,3,4 blinking

Hi,

I have a Dell Optiplex 780 and when I went to power it up the other night it did not power up.  I'm getting a solid amber light for the power button and lights 2,3, and 4 are blinking above it.  Any idea what this means?

RE: Dell OptiPlex - Solid amber light, lights 2,3,4 blinking

According to the 780 Service Manual page 13,

Solid Amber Power Light = Second state of the light at power up. Indicates the POWER_GOOD signal is active and it is probable that the power supply is fine. Look at the diagnostic lights for further information.

Page 15 shows that 2/3/4 = A possible USB failure has occurred. Disconnect and reconnect every USB device, then try to power on.
