Hi all, I have a problem with the screen on my spectre x360 13, Kaby Lake.
When the pc is on battery power, the screen flickers slightly (most noticeable on a grey background).
I updated the BIOS and the intel hd graphics driver today, but nothing changed. I previously disabled both the windows 10 adaptive brightness setting and the intel 'display power saving technology' setting, but no luck there either.
I'd be grateful if anyone might be able to help. Thanks a lot

Hi Mr Robot,
Thanks a lot for getting back and for your suggestions.
First, in answer to your questions:
- I don't think I made any recent software/hardware changes before the issue arose.
- I think the issue occurs in all screens when running on battery power. Sometimes the flickering doesn't occur (though most of the time it's there), but that doesn't seem to be connected to the software I'm using. I don't play any games so I'm not sure about that.
- The product name, as listed in the HP support assistant, appears to be HP Spectre x360 Convertible 13-w0XX.
Before getting started with your suggestions I also just wanted to ask a couple of questions.
- Sorry if this is obvious, but if I uninstall the graphics drivers, will I still be able to see the screen ok in order to reinstall them?
- In the instructions for the second suggestion, you say 'If your notebook is listed in the table' - could you send me a link to this table?
Thanks again, best

Thanks for your help. After reinstalling the graphics drivers, the problem is still there, and it does indeed look like the first picture (flickering screen) in the link you sent, so I will contact hp support.

I have a flickering screen but wilder than the demo on the support page it is fast and transverse rather than on/off.
Gone to support and will see what happens, this is not related to battery state, charing or not or processor usage.
It also doesn't do it on the attached monitor through the thunderbolt connection.
Wait and see.

I have a Kaby Lake Spectre x360, and after updating the Intel 620 graphics driver, I had the same issue: a fairly faint, slight but noticable flickering that's difficult to unsee once you've seen it. It doesn't start immediately after starting the machine, but maybe after an hour or so of using it, and it's especially noticable on a dark gray background.
However, I think I've managed to solve it.
1. Update your graphics driver just in case. You can do this by taking these steps:
Right click Windows 10 start button -> Device Manager -> Display Adapters (go a level deeper) -> Right-click Intel (R) HD Graphics 620 -> Properties -> Driver -> Update Driver. I now have version 126.96.36.19915
This updating actually didn't help for me (in fact, after this I actually first noticed the issue in the first place), but it's probably good to be up-to-date, especially if you already have this issue anyway.
Now for the real fix:
2. Right-click on your desktop and choose Intel Graphics Settings
3. Choose Power
4. Disable Panel Self Refresh, both for "On Battery" and for "Plugged in"
5. Hit Apply
6. You can now close this settings screen.
This should solve the issue you're having. Let me know if it helped! By the way, this is more of a general issue with Panel Self Refresh than an HP specific issue: if you look around with Google, you'll find many people are having flickering issues due to this Panel Self Refresh, which is just a power saving feature that's not really required. It happens on Lenovo too, and even on different operating systems like Linux.
