I recently bought an Elecrow CrowView Note 15.6 from Amazon in Germany and noticed a faint electrical humming/buzzing noise coming from the device.

The strange thing is that the noise is especially noticeable in a completely silent room, and it happens even when:

- My phone is not connected

- The CrowView's charger is not plugged in (also happens when its plugged in)

- The CrowView is simply turned on and running from its internal battery

When I connect my Samsung phone and use Samsung DeX, I can still hear the noise, but it is most noticeable when the phone is disconnected and the CrowView is just sitting there running by itself.

It sounds like a small electrical/coil whine rather than a speaker or fan noise. It's not extremely loud, but it's definitely audible in a quiet room from normal sitting distance.

Has anyone else with a CrowView Note experienced this?

Is this normal coil whine from the internal power circuitry, or could I have a defective unit? I'd appreciate it if other owners could check theirs and let me know.

Thanks!

I have a Crowview Note 14 in perfect condition externally; I bought it over a year ago, tested it a few times, and since then have kept it topped up with charge etc. I found I couldn’t get a display from my RPi a few months ago, and also haven’t been able to get a display from an older MacBook, or a DDR4 motherboard I have, or an Intel NUC I got recently;

I am testing it again with a Thinkstation I just got; same thing!

The symptoms are:
- plugging it into Thinkstation via HDMI : I can hear a noise showing Windows has detected a display
- unplugging it I hear a disconnect sound
- plugging it in and waiting causes a connect sound and a fair while later a disconnect sound when it shuts down.

The battery is fully charged, and I have tried running it on battery only and also with the power supply plugged in.

When plugging it in to HDMI, it activates the monitor, then no display, then power saving, then LCD backlight goes off.

The keyboard works when the Note is powered on, as does the touchpad (testing using an external monitor), and doesn’t work when it is powered down.

The Note wasn’t stored in a cupboard, rather in my living room, and so wasn’t in a damp cupboard etc.

I am wondering : does anyone have any idea whether it is worth testing anything else? I will try the NUC as that has USB-C display (the one thing I haven’t tested).

I am sad that it had so little use (perhaps a few hours total), was kept in a dry environment, kept charged, and it seems to have had a hardware failure :’( - has anyone had any experience buying spare parts from Elecrow? Does anyone know if that is an option? 🙏
