Does the power adapter or the controller have a high pitched noise?

I have had this item for some time and have never noticed a noise. I am pretty sensitive to noise, so I'd say no.

No. No noise at all. 100% happy/satisfied with this purchase. Product meets or exceeds all expectations. Good luck!

Generally there is some heat felt on the adapter, that's normal; nevertheless, check that the fans are running free of any resistance, like dust or lack of lubricant; this has a tendency to increase heat on adapter and cord.

Never have heard anything , but hums or noises could be resistance... either from outlet or heater unit itself.... but noise shouldn't happen.... prob wanna get that checked

I've had an R835 since issued -and prior Portegés- and have never gotten any clicking noises. The only thing I hear is the occasional, yet-quiet fan hum.

I have 2 of these units, and I don't notice any high pitched sounds. It's very quite. I highly recommend this

No...mine is quiet. I have been running mine 24/7 for 6 months...mostly powering two fridges and the stereo/tv when I need it. The fan will spool up and make some noise if it gets too warm. The only sounds mine makes is when my solar charge controller is in "Absorb" mode and the voltage is 14-14.4vDC. The noise is just the internal rectifiers...nothing to worry about.

I had the same problem, I had to move it, it was getting AC noise from the wall outlet, make sure all your power cords are away from it. (good luck)

There is no detectable noise from the power supply on my Tp-Link TL SG1005D.

Well, let me qualify my response, not unless the 'appliance' you have plugged in to happens to produce a humming sound. For whatever reason that is. LMAO!

I have never heard any high pitched tones ever come from my mouse...I'd say try and get it replaced.

I've never had that noise when running the plasmawave. Maybe check with the manufacturer for advice or replacement parts would be effective

Mine also makes a very annoying high pitch noise. My Braun OralB toothbrush has a similar transformer but does not make a noise. I'm going to contact Braun.

I have not had that occur. I wish I could tell you more about what is causing that noise. It might have done so, but I had mine installed by a professional and I was not there for the testing. I have not had a power failure so it has not had to kick in either, so I haven't heard it in operation.

there is some static noise yes..as with many amps...but if it is minimal when playing..you are good. If not, I would contact the seller.

Yes - mine squeals (ordered October 2014), I'm pretty sure it's an inductor or similar on the inside. Only occurs when a device is plugged in (so when the DC/DC inside is actually under load).

I would no rush to replace the power adapter just yet. If you can-try a similar power adapter with the same power and plug. IF you have one you can try it and see if the monitor fires up. If you have a compatible battery you can also try that. Normally the power adapter is OK. It is probably the monitor itself. I have never found a defective power adapter in all of my 52 years. I have seen circuit boards that are faulty on new products. If all else fails-ask the gift giver to exchange it for you.

I haven't had that issue. It sounds like you have a faulty adapter. I would try to RMA it.
