HP Notebook 15s-fq1095ns screen flicker after waking up from sleep

[virusauto]

Hi,

For some time now this notebook has consistently shown a screen problem when resuming from sleep. The screen will flicker when moving the pointer and it will be absolutely impossible to use it until a reboot is performed.

Some quirks:

• Resting the pointer on some locations may help the screen to retain a proper image. Things like the search box in the taskbar may (sometimes) help in showing a proper image.
• Using Ctrl + Alt + Shift + b does not help.
• The problem is consistently reproducible after letting the device sleep for some time. I couldn't tell what the minimum required time is for it to appear but it's probably beyond one hour.
• Updating the drivers, firmware and BIOS did not resolve it.

Hi @Treeko and thanks for your time,

I have tried following your instructions to receive agent support but it seems the web flow differ from your instructions. Anyway, I am not offered an option to contact an agent. This are my only options:

So it's either using a virtual agent, asking back here, using messenger or calling. Seeing as this is an obscure problem that is either caused by either the firmware or hardware, I do not think the virtual agent is going to be much help, also I am shy like that and I do not want to be on the phone so I would try the messenger, but I would much prefer for a resolution to be posted here so other users can benefit from it.

Thank you.

Regards.

After talking to an HP agent which just asked me to perform a UEFI/BIOS reset that did not fixed anything, I was told I would need to send the laptop for repair and, as the warranty is expired I would need to pay of my own pocket.

I am absolutely livid because this is clearly a problem on HP hardware part, particularly on how the device handles resume from deep sleep.

This only makes me double down on not acquiring any HP devices in the future. I have already had a pretty bad time with some printers and other laptops. They are just not good devices.

Thanks for your time.
