Book Edge 4, usb-c/display port doesn't work

[Dario F]

I just did the bios update from Windows 11 update system.

It moved from bios v55 to bios v60.

After the update the usa of usb-c as display port doesn't work at all.

The notebook doesn't recognize the external monitor (a Samsung one).

I moved from previous usb-c cable to the hdmi output.

@samsung support: please don't say to restore the notebook or check drivers as everything is updated and just before the bios upgrade everything was working.

Hi, was the Bios through the Samsung update ?
Sadly, dont think you can roll back a bios like the os.

The bios was through Windows 11 update (as I wrote above).

It rebooted the notebook and started the automatic bios update as it did more than once during past months.

I hope that at Samsung someone will fix the bios SOON!

It's really incredible that such a big company has poor quality assurance on this device! (not only about the bios, I've a long story with Samsung... )

I have the same issue. Display output via USB-C is broken. I have tested it with a Samsung monitor featuring a built-in USB-C hub and also with a Dell USB-C dock on another setup. I have the Samsung Galaxy Book4 Edge. I am shocked that such a large company would have such significant quality control issues. I am unable to revert to the previous BIOS, as the update occurred overnight without my knowledge. I only discovered it the next day, after experiencing the issues and reviewing recent updates. I rely on this USB-C docking station on a daily basis, and I'm not sure how I will manage my work without it.

Same here, i charge my Laptop  with Dell Dock and display Via USB c to Dell Dock and connected to Display Via DisplayPort and now it's suddenly not working!! and I have no Battery status!! What a Joke!! Samsung, Please FIx!

Today a new weird experience: after 2 hours the device self-rebooted. No errors in the windows events logger, no bluescreen, nothing.

Hey Samsung, good job with the new bios!!!!! 

I was an unhappy user, now I'm an angry user!!!!

Mine I think its after the "SAMSUNG ELECTRONICS CO., LTD. - System Hardware Update - 7/3/2025", things my USB-c Display stopped working. Anyone know where to turn on Battery Status? it seems to be not showing up anywhere in the Task or Battery sections? Help thanks!

[Dario F]

I confirm, the battery meter is not available anymore.

It's systemic, every 2 hours the device reboot! 

Great Samsung, really good job!

Now I'm invited to follow the law and take a pause every two hours and rest my brain and my eyes!!!!

It's really not possible that a company like Samsung is not able to deploy a stable firmware on a device whose price when was on the market first time was more than €2000!!!

Possible Cause

• Incomplete bios update when the system tried to do an overnight update automatically while being connected to the USB-C display dock

Issues

• External display dock via USB-C is not working
• Battery icon disappeared, and battery may not be charging
• Wi-Fi network is unstable – PC is connected, but thinks it is not connected
  • Conflict observed in some settings, pointing to connectivity, while others indicate not connected

Temporary Fix

• Upon reviewing Device Manager, it was observed that the following devices are not working properly
  • System devices/Samsung EMUEC Device
  • Universal Serial Bus Controllers/USB3 Controllers
• A rollback to an older driver temporarily fixed the display dock connectivity and battery icon issues, but other issues persist
• If I update the driver or scan for hardware changes, all the issues come back again

Suggested Permanent Fix

• A reflash of the BIOS should fix the issues.  

Historical Issues Observed on this PC since Purchase

• The second USB-C port (closer to the user) has not worked correctly in the past when connected to a USB-C dock. The keyboard connected to the dock via USB did not work when this port was used to connect to the USB-C dock.
• External display connectivity issues when using either of the USB-C ports to connect to the dock have been observed commonly. These issues have been temporarily fixed by disconnecting and connecting again.
• The external display dock used is built-in Samsung Monitor LS32D802UANXGO
