Display has vertical black bands

[witstert]

Display went to sleep. Stroked touchpad to wake up. Tapped touchpad and placed finger on fingerprint scanner. After bootup was completed I saw black>grey vertical bands rising from the base of the display to, at least, ¾ up the display. Took a screenshot of the display but the vertical bands do not appear on the screenshot. Not the first time this has happened.

Welcome to the HP Support Community! I'd like to help!

I see you are experiencing display issues with the HP Laptop. 

I have a few recommendations 

• Update your Notebook computer to the latest BIOS from HP.COM.
• Make sure the Windows and HP support assistant updates are up to date. 
• Check with an external monitor if the vertical black bands appear on the screen.

Try and check in Bios using the F10 key if the screen has vertical black bands in Bios. To enter Bios, click restart and keep tapping the F10 key and then turn on the PC at the same time to enter Bios screen. 

If the issue persists in Bios then it is a hardware issue on the screen. 

Hope this helps! Keep me posted.

The laptop is a HP Spectre X360 15". It is 3+ years old. It has a care pack that expires in October 2022 and that is the only reason I still have it. It has had a battery fail in it and has had the motherboard replaced twice. The 2nd replacement has left me with a laptop that has a touchpad that is extremely sensitive. I have de-sensitised it as much is possible. After the Care pack runs out I will get rid of it as fast as possible. Rant over.

The appearance of the black vertical bands has happened before. The laptop is completely up to date, firmware and hardware. I shut it down and rebooted this evening and no black bands. I am convinced that the fault lies within the display. 

Your advice is appreciated.
