H136483 - PC 300 6586 FAILS TO POWER ON WITH 220V                            
                                                                                
                                                                                
                                                                                
SYMPTOM:                                                                        
IBM PC 300 Series 6586 systems may fail to power on if the                      
power supply is set for 220 volts and connected to a 220 volt                   
outlet.                                                                         
                                                                                
PROBLEM ISOLATION AIDS:                                                         
The system may power on initially, however, after powering the                  
system off and then back on using the On/Off switch on the                      
system unit, the power supply will not function.                                
                                                                                
The power supply will function normally at 220 volts if the                     
system is powered off by disconnecting the system from the 220v                 
source, such as a power strip, surge suppressor or circuit                      
breaker.                                                                        
                                                                                
Affected power supplies are manufactured for IBM by Golden
