For systems with integrated graphics, replace the
system board.
Replace the system board.
1. Reflash the system ROM with the latest BIOS
image. See the "Boot Block Emergency
Recovery Mode" section of the Desktop
Management Guide on the Documentation
and Diagnostics CD for more information.
2. Replace the system board.
1. Check that the voltage selector, located on
the rear of the power supply (some models),
is set to the appropriate voltage. Proper
voltage setting depends on your region.
2. Replace the system board.
3. Replace the processor.
1. Check each option card by removing the card
(one at a time if multiple cards), then power
on the system to see if fault goes away.
2. Once a bad card is identified, remove and
replace the bad option card.
3. Replace the system board.
Press and hold the power button for less than 4
seconds. If the hard drive LED turns green, the
power button is working correctly. Try the
following:
1. Check that the voltage selector (some
models), located on the rear of the power
supply, is set to the appropriate voltage.
Proper voltage setting depends on your
region.
2. Replace the system board.
