Hi @Saurav143,

Welcome to HP Support Community.  

Thank you for posting your query, I will be glad to help you.

If you're experiencing a vertical line at the center of the display screen on your HP 15-Gw0000 laptop PC, it could be due to a hardware or software issue. Here are some steps you can take to troubleshoot the problem.

• Check for driver issues: Update your graphics driver to the latest version. You can do this by visiting the HP website, locating the support section for your specific laptop model, and downloading the appropriate driver for your operating system.
• External display test: Connect your laptop to an external monitor or TV using the HDMI or VGA port. If the vertical line appears on the external display as well, it's likely a hardware issue. If the external display doesn't show the line, it suggests a problem with the laptop's LCD screen.
• Physical inspection: Carefully examine the laptop's screen for any physical damage, such as cracks or pressure marks. If you notice any, it's likely that the screen itself is damaged and needs to be replaced.
• Safe mode test: Restart your laptop and boot into Safe Mode. To do this, repeatedly press the F8 key (or another key depending on your laptop model) during startup until you see the Advanced Boot Options menu. Choose Safe Mode and check if the line still appears. If it doesn't, it could indicate a software or driver issue.
• Reset display settings: Right-click on the desktop and select Display settings (Windows 10) or Screen Resolution (Windows 7). Make sure the resolution is set to the recommended value. You can also try changing the screen orientation to see if it affects the line.
• System restore: If the issue started recently, you can try restoring your laptop to a previous restore point when the display was functioning correctly. This can help revert any recent software changes that might be causing the problem.

I hope this helps. 
 

Take care and have a good day.
