Cannot connect my B248Y via USB-C anymore

acgs

Hello,

a few weeks ago I bought a B248Y monitor. At the beginning it all worked fine: I just had to plug in the usb-c cable into my laptop any had the display connected any could charge my laptop via the monitor as well.

It started becomming strange three weeks ago when everything worked fine (disply connection, webcam, internet connect) except my laptop was not charging anymore.

Another week later the display would not connect at all anymore. I had to charge my laptop via an external charging cable, then the display connection was fine again as well. Without the external charging cable, my laptop would constantly switch between being connected and not (The laptop was constantly switching between being charged and running on battery) and the monitor would stay black.

And today, final stage, I could not connect the monitor at all (even if a would charge my laptop seperatly). When I plug in the usb-c cable, for 1 second my laptop signals it is being charged and after that its gone. Display says no signal.

Connecting the monitor via HDMI-cable works, but then I cannot us the webcame. I tried to use a different usb-c cable -> did not solve the problem. I tried connecting via the display port cable -> did not work either.

Does anyone have an idea what the problem could be and how to solve it? Since it worked fine for at least the first two weeks, I think (or at least I hope) that the monitor itself is not the problem.

Thanks a lot for your help!

It might help if you could reveal your laptop brand and model number. Also, how old is its battery pack. Run a battery report as follows---

(1) Search 'cmd' in Windows start menu.

(2) Right click command prompt near top of menu.

(3) Click run as administrator.

(4) Enter 'powercfg /batteryreport' at command prompt.

(5) Then return to the desktop. Open file explorer.

(6) Then search for' battery-report.html' in the c:\windows\system32\ sub-folder. Double-click to open it in the browser.

(7) Post screenshot of the first part of the report if possible that compares design full charge capacity with its remaining full charge capacity.
