Random Screen jump/horizontal lines appearing for a moment, then disappearing

[Copn]

Hello, I recently bought an HP Laptop 15-bs0xx, and when I had used it for about a week I noticed that sometimes it would have the screen jump a bit and horizontal lines of black and white appear over the screen, then they would disappear and everything would be fine. I ignored them for a while, but since it seems to be happening a bit more, I thought I would go to the forums to see if you guys had any tips to help me with my problem, or if I needed it to be replaced. I do not believe that I have had any recent software of driver changes because as I said, it only started happening a week after I had bought it. If you need any other information, I would be happy to provide it. Thanks!

Let me take a moment to thank you for posting on the HP Support Forums. 

I understand that you have an HP Notebook15-bs0xx. I read that there are display issues. The display flickers and lines appear. Not worry, I'll do my best to help you. 

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

• Power off the laptop.
• Remove the battery out. If the battery is integrated and does not have a latch to release it then leave the battery inside the laptop.
• Disconnected AC adapter from the laptop.
• Press and hold the power button for 15 seconds.
• Reconnect the battery and plug the AC adapter.
• Power ON the laptop.

Please test the display in BIOS. The following steps will help:

• Shutdown the laptop.
• Power on the laptop and hit the f10 key repeatedly (7-8 times). This will load the BIOS.
• Let the laptop remain in BIOS and you may observe the display.
• If the display flickers or has lines then it confirms a hardware issue. In such a case you may contact our HP phone support to check the available hardware service options. 

You may also run a hardware test on the video by following the below steps:

• 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 - 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.

I sincerely hope this information helps. Let me know the outcome. Cheers!

Thank you for responding to me!

I did all of the steps you asked me to, and when I did the BIOS I waited there for 15 minutes, and for the UEFI it said that I passed them all. I haven't gotten another display flicker yet, but I will tell you if I do, thanks!

I have been using the computer some more, and have noticed the flickering has appeared again. Should I just contact HP through phone?

Thanks for your reply. Yes, you may contact our HP phone support. There could be a connection issue which is causing the display to flicker. 

Let me know if you have any questions. All the best and take care!
