Constant beeping with Dell laptop when asleep using docking station

[MtnCampus]

Hi,

We are trying to figure out the constant beeping when we lock our laptops.  It's making the USB sound like connecting and disconnecting.  I notice it starts when the monitors go to sleep.  Using Intel graphics software.  Here is message from logs.

{"category":"Program","level":"Debug","message":"Resetting graphics controller due to PnP event ..."}

Any ideas?

Hello MtnCampus,

Thank you for posting in Intel Communities.

To get a better understanding of the issue and be able to provide an effective recommendation, please provide the missing key information here:

1. Does your docking station work fine without these error logs and beeping sounds normally?
2. What happens when you connect your system directly to the monitor using a cable (bypassing the docking station)?
3. Was this setup working properly before without these issues? If so, were there any recent changes made to your system, drivers, or hardware configuration prior to this problem starting?
4. Could you provide details about your docking station (model, manufacturer)?
5. What cables are you using to connect the docking station to your laptop and monitors?
6. What are your monitor/display specifications and current configuration (resolution, refresh rate, number of displays)?
7. Could you generate and provide an SSU (System Support Utility) log file? This will help us analyze your complete system configuration and identify any compatibility issues.

This information will help us determine if this is a docking station compatibility issue, driver problem, or power management configuration matter.

Looking forward to your reply.

Best regards,

JeanetteC.
