Dell XPS 15 9550 01.02.10 BIOS

Today I installed the BIOS and number of drivers updates - I didn't experienced before the screen flickering at low brightness but now it's non stop if I'm on power or if on battery. Something that apparently this BIOS have fixed - any suggestions?

Hi Guys,

Are either of you using the TB15 dock with your systems?  If so, it sounds related to this article, which suggests installing the latest graphics driver.

Let me know if that was helpful or not.

Thanks,

Brad

I am not using the TB15, and I have the latest graphic drivers for both the Intel and NVIDIA.

The flicker is on the laptop screen and not an external monitor. It started right after I installed the latest bios a week ago. Is there a way to roll back to the previous BIOS as a troubleshoot to the problem?

Thanks Brad.

Hi Tradosh,

Go ahead and try reinstalling the video drivers to see if it changes anything. I can send the link if needed. I am also going to send you an email  (to the address registered on the forum) asking for your Service Tag to look into this further (if the drivers don't fix this).

Best regards,

Brad

i have reinstalled both drivers and flickering is a bit less frequent but still to frequent for comfortable use

Thank you both for the quick replies on the Service Tags, I am going to find out what options we have and will get back with you both hopefully by tomorrow. I am trying to reach a member of our Software/Driver team and will see about the BIOS rollback as well. I am not aware of anything at the moment but will find out.  

Best,

Brad

an interesting observation it's not day 3 of the BIOS and number of time that screen is flickering per minute goes down, so it's less frustrating - but interestingly there have been no drives updated since 😕

I opened a service ticket when the problem started, few days ago, and finally got a replay with a link to download the previous BIOS - 1.2.0. Downgraded the BIOS, and so far the system has one without LCD flicker for almost 30 minutes. It seems like the new BIOS is an issue (for at lease my system) so I will hold off upgrading to new BIOS for now.

Will let you know if anything changes/
