Having problems with your Dell OptiPlex SX270 PC Desktop ?

My computer will not power on - Dell OptiPlex SX270 PC Desktop


Answers :

My Dell SX270 will not start up when power switch is initiated. I tried another power supply from my second operational SX 270 and it made no difference. Normally when you pull the power plug (DA-1) from the back and replace it you will hear the internal fan start-up and you will see several leds internally light. On the unit with the problem I only see one (1) light and the fan does not come on as it does briefly with my other working SX 270. What are your suggestions???
