eMachine power supply

I am working on an eMachine that does not turn on when the power
button is pushed. The button appears to be OK. I suspect the power
supply but cannot find any information on it. I do not want to buy a
power supply and find out that there is more wrong than that.

When I plug in the power cord, there is a green light on the power
supply that comes on and then goes out right away. I can hear buzzing
in the supply but have no way to test it as the computer does not turn
on. Is the LED power supply light working properly by turning off
right away or should it stay on when plugged in?

I have read some of the posts regarding shorting pins out on the lead
and am not comfortable doing this.

Sometimes you just have to take a chance and buy a power supply.
Especially if you are not a technician with the skills and equipment to
properly test the subject power supply.

I would call eMachines tech support. I have found them to be very helpful.

Are you aware that eMachines had a problem with their computers where
the PSU would blow and take out the motherboard?

No, this is not my computer, I am fixing these in my spare time on a
learn as you go basis. I do not have a tester so I thought maybe
someone with an eMachine or a good knowledge of hardware could tell me
if there is any significance to the LED light going out. I do not
have a lot of spare parts lying around so I do not have a good power
supply except in my own machine to test it. Spending the $40 to
replace the PSU and then finding out that it is also something else
would not be good for me or the owner. I will probably try to attach
my PSU to this computer and see if it will turn on. This is an older
computer, around 6 years and probably needs a new CMOS battery as
well. According to what I was told, the computer worked one day and
was dead the next.

I'd try a different power supply. You can't usually fix things
without some spare parts around, and e-machines often use garbage
power supplies. If you're typing on a computer, does it not have a
power supply?

That is what I did, and it appears to be dead. Thanks for any and all
help.

psu's are the most common fail point in my experience, so if you dabble
with computers and offer to help friends out etc., then having a spare
psu is a handy thing, saves dismantling your pc to use that psu as a
test, and I'm pretty sure you will know someone with a psu failure before
too long... if its not your own pc... that final extra usb device, hard
drive or graphics card that pushes it over the edge on one of its rails...
