Precision 5530 and TB16 black screen flashing/flicker

I guess I was to fast - shortly after I wrote the last post I got it back :(

Intel graphics driver updated. 4h of using P5530 and I get only one screen freeze. Why Freeze? Because orginaly I was geeting screen freezing problem - no responce from keyboard and mice on screen but I was acctualy typing / clicking in notepad. After I've disabled Modern standby my freez problem changed to black flicker problem
To be precise:
1. I was getting flicker(orginally freez) only when using laptop display without any external monitor(I use tb15 dock and 2xQHD displays. When P5530 is docked I don't use laptop display) after in some case P5530 was woked up from sleep. Same as everyone else but without TB16
2. Modern Standby is disabled in Registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power - CsEnabled value changed to "0"
3. Im using Win 10 1903 bulid 18362.1 - yup, I've updated Win to "beta/dev version" since Dell is still lokking for solution

So in my case: Drivers posted by @snruebes  + Modernstandby disabled in registry + beta/dev version of Win 10 = 4h of work and ONLY ONE freeze / flicker

BTW: Intel in 25.20.100.6519 version is saying to "fix" Better support for Windows* 10 Ambient light sensor framework and Power and performance improvements https://downloadcenter.intel.com/download/28514/Intel-Graphics-Windows-10-DCH-Drivers

Ah yes, I also have modern/connected standby disabled with that regkey because without it my laptop never really sleeps, and in under 8 hours (or overnight) the battery goes to 0% if not plugged in. Disabling Connected sleep fixed that.

I have the same problem with a new Precision 5530 and a WD15 dock.  Using the latest drivers and firmwares according to Dell Command Update.

This issue isn't isolated to just this model tho ... I currently also have this problem to a much lesser extent with 7x80 and 7x90 series laptops (also with WD15 docks) we've rolled out.  Historically I've also had "blinky blinky syndrome" on the Precision 5510s but that went away after some driver/BIOS update combination last year.

The switch to USB-C/Thunderbolt based docks has been a massive step backward in terms of reliability for Dell ... its been very disappointing.

I am experiencing the same issue with Precision 5530 and 240W TB16 dock.

When using laptop screen (UHD) with external monitor both screens periodically go black for a second or two. System is fully updated. 

A lot of people seem to be having this problem. Has it been reproduced or acknowledged by Dell?

Hi all, 

Thanks for your continued updates on this thread. We are aware of the issue and are currently investigating the cause and working towards a solution. This can take time to develop and implement. It may not the most workable solution for everyone, but it may be worth disabling the option of putting the system to sleep or hibernate until the solution is found.

I'll keep the thread updated whenever I hear anything else.

Thanks again for your patience and continued input.

i might give you some numbers

we have about 1200 devices in our company. All are connected with the Dell WD15 Dock (not TB). All devices are connected to Dell UltraWide U3417 monitors.

293x Precision 5510 -> no problem
266x Precision 5520 -> no problem
124x Precision 5530 -> All have this issue with flickering
except if you stage the device with Windows drivers only (without running Dell Command Update)

interesting also it does not happen while the lid is closed and only second monitor running.

Hey @msconfig1987 , 

Engineering have requested more info from you. I have dropped you a private message. If you could respond to it it would be greatly appreciated.

Maybe it's too soon, but I installed the newest ISV certified NVidia Driver (I have the P2000 card) yesterday morning, and have not had the issue since.

It was, in fact, too soon. Came back from lunch and having the issue.
