Hi @Raja1085,

Welcome to HP Support Community.

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

If you're noticing a dark patch on the bottom taskbar of your HP laptop after restarting, it could be due to several factors such as display or driver issues. Here are some steps you can take to troubleshoot and resolve the issue.

Restart the Laptop: Since you mentioned the patch appears after a restart, try restarting the laptop again to see if the issue persists. Sometimes, display issues can be temporary.

Update Graphics Drivers:

• Go to Device Manager > Display Adapters.
• Right-click on your graphics driver and select Update Driver.
• Follow the on-screen instructions to search for updates automatically.

Adjust Display Settings:

• Right-click on the desktop and select Display Settings.
• Check the resolution and scaling settings. Sometimes incorrect scaling can cause display anomalies.

Check for Windows Updates:

• Make sure your operating system is fully updated. Go to Settings > Update & Security > Windows Update and check for any pending updates.

Check for External Display Issues:

• If you use an external monitor or projector, try disconnecting it to see if the issue persists on the laptop screen alone.

Perform a System File Check:

• Open the Command Prompt as an administrator and type sfc /scannow, then press Enter. This will check for and fix any corrupt system files that might be causing display problems.

Test in Safe Mode:

• Boot into Safe Mode by restarting the laptop and pressing the F8 or Shift + F8 key during startup. This will help determine if the issue is software-related or caused by third-party programs.

Check the Display Hardware:

• If none of the above works, it's possible that there could be an issue with the display itself, such as a hardware malfunction or a loose connection.

I hope this helps.

Take care and have a good day.
