I am working on an hp pavilion 310n that won't turn on at all.
When I plug in the power supply the green LED next to the fan briefly lights up then dims out.
There is no activity when it is plugged in and the power button is pressed.
I tried shorting out the green wire with one of the black wires and plugging in the PS but the same thing happens.
The LED lights up then dims out. The fan on the PS won't spin at all and no sound is coming out of it.
This looks like to me the PS is shot. I just need to confirm this with somebody...preferably someone who is familiar with this make and model.
