Hi Kerberg,


Can you try the following troubleshooting steps to see if it's hardware/software issue:


- Connect the notebook to an external monitor to see if the line appears on the external monitor.


- Go into BIOS by tapping "F10" key during boot up and see if the line appears on your main display. If it doesn't occur in BIOS, the hardware is good. We will have to focus on video drivers- onboard and discrete card. If the line appears on the screen, please call 800-334-5144, say notebook and then zbook through the promot.


Thank you,
