Coil whine

[Appelzaadje]

Hey techie's,

If a pc makes a high pitched noise while off does this mean coil whine ? And if yes is this something a manufactor will replace under waranty.

When the Pc powers on the noise disapears.

Sorry for the bad grammer i bet i misspelled a lot .

Must be your power supply.

Can you give some more details

Like what's plugged in or connected nearby

 

I've had in the past some speakers that when not receiving signal from the PC they would do a noise

Well. An Acer, huh? So desktop... power supply! or dedicated graphics card.

im guessing since it only happens when the pc is turned of it is most likely the PSU to bad i dont have the pc here atm to verify this but still no closer to coil whine being a warranty issue or not

It is the power supply; they still have current going through them when they are off.  Most power supply vendors will replace a unit for coil whine, but you would have to check with Acer to see if their warranty covers it.
