getting disconnect sound, followed by one or more reconnect sounds

I run an ASUS laptop, Win10 Pro 20H2 build 19042.746, see my specs for computer details. At random and more or less one to a dozen times an hour, the laptop will give a disconnect sound, followed by one or two connect sounds. (These are the sounds I get when I unplug or plug in a USB device.) But I'm not connecting or disconnecting anything at all, it happens when I'm not touching the computer.

If I'm typing, often whatever I'm typing into stops getting the input. This is at worst inconvenient and leads to typos. I have to wiggle the mouse or hit enter to return to being able to type where I was.

Worse is: when I'm running my observatory and have several well designed commercial packages working together to control three separate hardware devices, they stop working together, sometimes get disconnected from each other, and I lose control of where the telescope is pointing.

How do I find out what is disconnecting and reconnecting, so I can disable it? I've tried event viewer as suggested elsewhere, but it seems to only record errors, warnings, and "information" and don't have timestamps that relate to the random behavior. I'm optimistically (and ignorantly) thinking there should be a log of (or a way to log) every single time something connects to something else in the computer (software AND hardware). I looked at device manager, and what I see is when I connect the same device again, the only events noted there are associated with days or years old information, related to the first time recently I connected it.

My work laptop, which is heavily managed by my employer, also has started doing this. It is a Dell Inspiron and has been getting worse, especially it seems when I'm connected to the internet but NOT connected to the VPN.

When I run the ASUS laptop in Safe mode with network, The Problem Stops (with the observatory coming disconnected) But I don't know if the sounds stop because audio is disabled in safe mode. but running in safe mode is not a long-term option for the observatory because the observatory needs alot of services, I think.

Right-click on start and choose "Event viewer". Expand "Windows Logs" and then select the "System" log.

When you hear the device connect / disconnect sound, note the time and wait a few seconds for the logs to get updated. Event viewer should indicate "New events available". Perform a refresh and review the details of the latest logs. Maybe this can give you an idea of what is happening.

Do you have devices connected by Bluetooth? I have heard that BT connectivity can be unreliable and disconnect/reconnect.

I believe Bluetooth is a possible issue with the work computer (which is annoyingly active in the beeping category) but there's not much I can do about it.

I don't use bluetooth on the observatory computer. But there's 4 bluetooth drivers listed in device manager. When I turned off Bluetooth in control panel/devices, only one remained: Qualcomm Atheros Bluetooth 4.0 using a driver version 10.0.0.1 dated 7/27/15 provided by Qualcomm Atheros Communications.

I disabled that. Will observe for a while.

Thanks hsehestedt for the cool clear post. Now I can observe things happening better.

BT driver date is very old so maybe incompatibility iisues now that Windows 10 is no longer the same 'beast' as it was 5 years ago in 2015.
If it turns out to be BT related then update all BT drivers. I believe that the latest Windows 10 now gives you drivers through the 'Optional updates' option rather than via Device Manager.

I have a few thoughts: It was noted that this issue happens when the computer is not been touched at all. Does it ever happen while the computer is being used? If not, could it be related to sleep settings?

It might also be worth looking at the settings for individual devices and prevent the system from putting them to sleep as in the sample below. Try turning that setting off:

After observation with bluetooth off and old BT drivers disabled, AND with the knowledge of how to use event viewer to identify "what just happened" when the disconnect/reconnect sound happens AND verifying nothing is trying to put the computer to sleep (I love sleeping personally, but I have set up all my computers to never sleep because I hate the fiddly reawakenings in a network environment), the computer calmed down somewhat.

Sadly, a power failure caused me to have to go back to an old restore point that did not have my astronomy software loaded correctly. So I also had to do some clean software installs to get my observatory reconnected to attempt to duplicate the problem or verify problem solved, and so I'm not sure if legacy versions of the software were creating the problem.

But I don't have the problem today. Solved for now, and if I'm wrong I'll start a new thread with any wisdom gained.
