Restoring the Power Supply
To restore normal power supply operation, follow these steps:
1.
Turn off the computer and leave it off for at least
30 seconds to reset the power supply logic.
2.
To determine the cause of the high temperature and correct
the condition, check for the following:
Ci
Room temperature above 95°F (35°C). If this is the case,
relocate the computer to a cooler area.
Ll
A blocked power supply fan. Make sure there is space
around the power supply fan vents in the back and
sides of the computer case. Remove the computer’s
cover and check both inside and outside the computer
for blockage. Make sure there is ample room around
your system for air circulation.
Cl
An overload
of
the power supply limitations. Check the
table on page 6-8 to see if you have exceeded the option
slot power limits. See your option card manual(s) for
the power requirements for your option card(s).
3.
After you correct the problem causing the overheating,
allow the computer to cool down for at least five minutes at
room temperature (about 78°F or 25°C). This resets the
thermal detection circuits.
4.
If you removed the computer’s cover, replace it now. Then
turn on the computer.
If the power supply shuts off again, contact your dealer.
