Laptops beeping after update when connected to multiple monitors and docking station

We are also having this issue. We reset the docking station, but the issue recurred the next day. 

All of our stations have two monitors.

OS: Windows 11 23H2 November 2025 update

docking station: WD19S

Firmware version: 1.1.4

Lapmargin: 0;">BIOS version: 2.6.1

monitors: 2x P2225H

S3 sleep mode turned off (BIOS setting on), turned off USB powershare

A little more information on our side: The laptop doesn't have to be asleep. It happens when you lock the Windows screen.

We are also experiencing this issue.

Affected models:
Latitude 7440

Latitude 7450

Pro Max 14

All affected devices are on Windows 11 Enterprise, 25H2 version. BIOS 2.7.4.

The monitors being used are P2725HE with the docking stations built in. We're also seeing this on the WD22TB4 docking stations. As mentioned by other posts, this is only happening when a second display is connected to the docking station.

Seeing this on a Pro Max 16 and Latitude 7450 both on WD25 docks with multiple monitors.

We found a solution. Not ideal, but it has worked for us. Our monitors have cameras and soundbars plugged into them. It appears to be happening when the monitors go to sleep. 

So, we set the monitors to never go to sleep.

In Settings:  Click "Personalize" > Click "Lock screen" > Click "Screen timeout" > Click "Screen, sleep & hibernate timeouts" then set both to "Never"

Hope this helps!

We began having this issue on most of our Latitude 3520s towards the beginning of the December and we think we narrowed it down to the latest Intel Graphics driver 32.0.101.7077 update as we started noticing the issue the day after it was applied. Also in the Windows event log you can see events related to the Intel graphics software about the resetting the graphics controller.

Hi everyone,

Thank you for bringing this to our attention!

To help us escalate this to our engineering team, we kindly ask for the following: A short video showing the issue, if possible.

This will greatly assist in reproducing and diagnosing the problem. Please share the video in this thread or via a secure link.

Your input is critical to speeding up the investigation and finding a solution.

Thank you for your cooperation and for being part of the Dell Community!

Here is a video from one of our users.

@Mtndugal Thank you for sharing the video.

They are all Dell Pro 16 Plus PB16250.

This is also happening with a very good amount of devices in our company.

From Latitude 5530/5540, Precision 3581, Pro 14 Plus, etc . . .   They are over 200 devices affected and has caused a huge amount of tickets and user complaints. 

We use the Dell Docks WD19 and WD19S mostly with 2 displays connected but this issue is also happening when a single monitor with charging capability is connected (Dell UltraSharp or P2425HE, U2424HE).

We start receiving reports of the 4th Dec (one day after the first post here) and I can confirm that the Intel Graphics driver is 32.0.101.****

Definitely something was messed up somewhere and it would be good to have the fix as soon as possible.

Here's a rundown of my experience with what I believe is the same issue. When left in the "chiming" state for a longer period of time I believe it also caused a BSOD crash. Also below is a video of the issue occurring. 

System / setup

• Dell Precision 7680 (Windows 11), BIOS updated via SupportAssist on 1/2/26 (BIOS 1.26.0 + NVIDIA driver A35 installed 1/2/26).

• Dock: Dell WD19TBS (TB dock).

• 3 external monitors (different makes) connected through the dock. Laptop lid closed.

Issue

• After locking the PC (Win+L) and allowing the displays to turn off / system to go idle (lid closed, docked), the system repeatedly plays the Windows device connect/disconnect chime every few seconds. External monitors remain black. Issue began after recent Windows + Dell updates (installed around 1/2/26).

Evidence from Event Viewer

• During a reproduction test (Win+L → wait for displays off → chimes start), the System log shows repeated Thunderbolt link/device re-enumeration for the dock:

  • Source nhi logs “Thunderbolt device is disconnected” and “Thunderbolt device is connected” for “WD19TB Thunderbolt Dock” in rapid succession, correlating with the chimes. The connect event reports Device NVM version: 60:0.

  • The Thunderbolt driver logs transitions into RTD3 (runtime low-power) and explicitly notes DeviceDisconnected/DeviceConnected events may occur, matching the repeated chime behavior.

Related crash (likely caused by the same dock connect/disconnect behavior)

• I believe the repeated Thunderbolt dock disconnect/reconnect cycling (described above) — if allowed to continue long enough during lid-closed/idle — is what led to a BSOD and reboot.

• Evidence supporting this linkage:

  • The reboot was from a Plug-and-Play fatal error: Event Viewer shows BugCheck = 0x000000CA (PNP_DETECTED_FATAL_ERROR). This bugcheck type is consistent with a driver/device power-state / enumeration failure.

@vande424​ 

From my troubleshooting, the sound is actually just the "Device Disconnect" (Windows Hardware Remove.wav).

If you open "Change system sounds" and change it to "none" you won't have the beep noise anymore. Or if you change to some other sound it will play that one instead. 

Of course where they .wav file is located is hard to manage in terms of permissions or GPO as this is located in C:\Windows\Media. 

Tried a few things playing with Registry Editor but deleting the Computer\HKEY_CURRENT_USER\AppEvents\Schemes\Apps\.Default\DeviceDisconnect or changing the value to nothing makes no difference. 

Workaround so far is to change that sound/noise manually to "none" for the time being instead of unplugging screens from docking or unplug the dock from the laptops.

 

Seeing the same issue on our machines. Dell Command Updates did not resolve and a replacement dock did not seem to make a change either. Did anyone roll back the Intel Graphics driver and have luck? We have issues with a 7430 and a 7440 right now. 

@DELL-Nat M​ we have the same issue with Dell Pro 14 Premium PA14250, Latitude 7440, Latitude 7450, Latitude 5540.
