There is an error in the main power
(5V) circuit. This could be due to
something in the 5V circuit that is
poorly seated or out of specification.
This includes I/O cards, the memory
expander card, hard disk drives,
optical drives, floppy drives, the
system board, and the power supply.
1. Reseat the power connections to
the hard disk drive, floppy disk
drive, and any optical drives.
2. Try to narrow down the device
causing the problem by removing
the power connection to the hard
disk drive, floppy disk drive, and
any optical drives one at a time,
restarting the Workstation after
each change. If a single device
seems to be the source of the error,
replace the device.
3. Reseat the 32-bit PCI and AGP I/O
cards and the memory expander
card.
4. Try to narrow down the problem by
removing the I/O cards one at a
time. If a single card seems to be
the source of the error, replace the
card.
5. Replace the power supply as
described in “System Memory” on
page 159.
6. Replace the system board as
described in “System Board” on
page 186.
