RE: Precision T5500 Pb7 Error

1100 Watt power supply is required.  You have a smaller power supply.

flashes the Pb7 error code, which translates to:

ACPI S0, hand off to BIOS control

System on. BIOS not execution. This is the transition state to POST states.

Solid Amber — System fault(Motherboard), but +5VSB Power Supply is good—normal operating state (S0)

BIOS must be updated BEFORE changing CPU.

Pb7 is dead motherboard/cpu
