Help me with the green light that is showing on the back of my power supply in the computer. A light is blinking on an d off as I am trouble shooting. The light started blinking on and off after I plugged it in the wall socket. Please give me feed back as to what the problem could be. I am still working!

what the make model of computer and power supply, if its working fine i wouldnt worry if its green its probably just to signify its recieving a supply from the mains, possibly flashing because theres a bad connection or that case has been opened.

Some Power Supplies have a light on it to tell you if it is still working or not. I see these mainly on Compaq and HP computers. Normally if the Green Light starts flashing that means that the Power Supply is starting to have problems. The light is suppose to be solid
