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
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.
