Thanks for reaching out to us on HP Support Forums. 🙂 I came across your post and would like to help.

I understand that you have an HP Pavilion 15-p077tx Notebook PC and are facing a display issue. I read that the screen gets darker on the right side of the corner whenever you touch it. Thanks for sharing the image. 

I would like to know the following information to assist you better:

• Do you recall if there was any object in between the screen and the keyboard when the lid was closed?
• Did the laptop fall down, etc?

Meanwhile, I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

Let us run a video test:

• Hold the power button for at least five seconds to turn off the computer.

• Turn on the computer and immediately press the F2 key repeatedly, about once every second.

• The HP PC Hardware Diagnostics (UEFI) main menu is displayed.

• Select Component tests.

• Please initiate a video test. 

  This test includes 3 tests of the video hardware on your computer. Select one of the following tests, then click Run Once.

• Video Memory Fast Check - 3 minute video memory test

• Video Memory Check - 20 minute memory test

• Palette Check - 1 minute test of the three video color components. Follow the on-screen instructions during the test.

If the test passes then restart the laptop and tap the F10 key repeatedly to get to the BIOS. In BIOS please test the display. If the issue persists in BIOS then it is hardware issue with the screen. You may contact our HP phone support to explore the hardware service options. 

I hope this information helps. Please feel free to let me know how it goes. All the best! 🙂

My HP PC Hardware Diagnostics (UEFI) main menu is different, it has only a few options to Diagnose.

And no I have not dropped my laptop and there was no object in between the screen and the keyboard.

Hi @PGautam,

I reviewed the post comprehensively. A remarkable job was done to isolate the issue. Kudos to you for that. As @MKazi is out of office for the day, Ia m jumping in to assist you here. Please try these steps:

Please go to control panel> programs and features>

Then uninstall the UEFI diagnostics

Then reinstall it from this link and download "Download (v. 6.3.0.0)" Then install it. 

Then run the UEFI video diagnostics as mentioned. If you still receive the same options in UEFI as before, then don't worry this is what has been installed on the computer based on the components that you have. It is relevant to the specific components that you have.

Another way of checking if the display becomes dark is going to the bios and checking it there by touching it.

•  To do this, please keep tapping the Esc key gently several times as soon as you power on the computer.
•  It takes you to the startup menu.
•  Then press the F10 key to go the bios.
• Please touch the touch the Right Side of the screen.and check if the screen becomes darker.
• then press the F9 key to load bios defaults. Then press F10 to save changes and exit.
• Then return to Windows

If the screen becomes dark in the bios, then the computer has a hardware issue and it needs to be serviced by contacting HP phone support.

Step 1. Open link: http://hp.com/contacthp

Step 2. Enter Product number or select to auto detect

Step 3. Scroll down to "Still need help? Complete the form to select your contact options"

Step 4. Scroll down and click: HP contact options - click on Get phone number, Case number and phone number appear.

They will be happy to assist you immediately.

If the unit is under warranty, the manufacturer’s warranty should take care of it for you.

If it does not happen in the bios, please try these steps:

Please uninstall the display drivers completely from device manager.

• Right-Click on start button> click device manager> Display adapters>then select the display drivers and right-click on it and uninstall the graphics drivers.
• Please check the box that says “delete the software for this device”.
• Then restart the computer and check again.

Then update the bios, chipset and graphics drivers from this link and check again if the issue gets resolved.

Please keep me posted. I will keep a watch for your reply.

Hope this helps.  Let me know how this goes. I genuinely hope the issue gets resolved without hassles and the unit works great.   Please reach out for any issues and I'll be there to assist you.

I used USB Pendrive For UEFI diagnostics and done the video components test but all the three tests are passed.

But when I check through Another way by touching the Right Side of the screen in bios, the screen becomes darker.

I think my computer has a hardware issue.

Thanks For Your Support.
