Dell Precision 5510 Owner's Lounge

Just over a week.

If the updated BIOS was causing problems then there would be more posts in this forum. The lack of posts about the BIOS update is a good indication of no problems.

True, sounds logical. There were / are some problems though among XPS owners but i did not find many issues among 5510 users.

 

I did the Bios update to 1.6.1. and i did not detect any negative side effects. Resuming from standby seems a tad slower but this might be due to a Windows update or it might just be my imagination. I noticed no increased fan speeds, no flickering of the screen, no freezes or reboots. It looks like the battery life is increased but again this might be placebo.

I got a scare when the 5510 rebooted and Windows updates were also installed, strange because the Windows update log (recently installed updates) did not registered any but all went fine. It took a few minutes for Windows configuration to be completed upon boot, it remained a (short) while on 100%. But all seems well. I have been on 1.6.1 for 3 days now.

 

If anyone else has the UHD screen and experiences uncontrolled screen dimming like the FHD and QHD please do post and tell!

Downgrade of BIOS to 1.5.1, as suggested by John kindly, doesn't work. The Intel CP suggested by Aaron don't effect either.

I've been in extended contact with Dell and they're fully aware and not in denial either. It's gone back to Product Division, which afaik means they're actively re-coding or at least in process of examination of the issue since it was brought to their attenion.

It looks like this, and happens even when adaptive brightness AND sensors in services.msc are disabled:

Will update when aware of progress.

Hi folks. Got an issue to report, see if anyone else has had similar issues. Had this since the beginning, so it's not a newly malfunctioning driver issue.

I run 3 external monitors, all Samsung 32 inch curved monitors. The laptop display is powered off at all times unless I'm using it with no monitors connected, no problem there. Just run it with the lid open for cooling issues.
The first monitor is connected directly to the laptop w/ a USB C to HDMI cable that plugs into the USB C port on the laptop.
The second is connected via an HDMI port on the back of a USB 3 hub (this one: https://www.amazon.com/gp/product/B00ECDM78E/ref=oh_aui_search_detailpage?ie=UTF8&psc=1).
When I wake the computer from sleep, these two start up just fine every time.

My third display, however, is connected via HDMI directly on the side of the laptop, and it almost never wakes back up after sleep (it will start up one in every 30-40 times). I have to reach down and unplug/replug it every time I wake the computer. As soon as I do this, it wakes up. It's quite inconvenient and I'd love to never have to do this.

I've switched cables, no luck there. In advanced power settings, I have PCI express Link State Power Management off. I have screen savers off. Power settings are on high performance. I can't find any settings that could be causing this.
I also know that it is NOT the monitor, it's something w/ the software or hardware in the computer because when I physically switch the monitor positions and hookups, it's always the one connected via the computer's HDMI port that fails to wake. Please help!

One more note, Windows appears to believe that the monitor IS in fact on. I know this because applications that I had open on this third monitor when I put the computer to sleep do not get migrated to either of the other two screens, and if you right click on them from the start window to minimize them, you see the animation of them zooming down on my center (main) screen from where they would have been on the turned off monitor. And if you then maximize the application from the same display, you see it zoom back out towards the monitor that is off.

I have my precision 5510 w/ the Xeon E3-1505M w/ Nvidia Quadro M1000M.

As a side note, under Nvidia's control panel settings, the only settings options I have are for 3D settings, nothing about display settings. Anyone else have this issue.

 

I can at least answer this one for you. This machine runs with Optimus and that is the only configuration. This means that the Intel GPU handles all display output and the NVIDIA GPU is only used for rendering support. So, the Intel graphics control panel is where you need to be looking for display options. (However, I have no idea what setting might fix your HDMI problem.)

We have a bunch of these units at my office and they all use the TB16 Thunderbolt dock for external monitor configurations, without any trouble.

 

Matthew, you need to verify the same HDMI problem is happening with different screens on the same cable, with a different cable an same screen, and verify the same screen on the same cable on a different HDMI source.

If you don't want to fiddle-arse around and have already tried what Aaron suggests, have you also tried doing a factory reset on the screen concerned? It may have issues with power timeout. There may be a trigger voltage not getting through or something...

Apply rigour to your methodology before going to Dell support if you still have problems, and also do their diagnostics prior to a call, as it records the results and means they can't fob you off and ask you to call back before you request a site-visit.

Good luck!

I already did that:

Using the same cable I ran it to a different monitor, and still got the same problem. When switched, the problem only manifested on the DIFFERENT monitor that was now connected via the HDMI port. And the one that was previously not waking had no trouble waking up after switching. Like I said, the problem is unique to the whichever monitor is presently hooked up to the HDMI port on the laptop, not any specific monitor or cable.

 

Another odd thing that may help explain things? Intel's graphics program only detects the left and right monitors, and not the center (even thought the center is my main screen). Oddly enough, it's the LEFT monitor that is the one that doesn't turn on. (First photo)

But, Windows display thing does? Anyone experience this or can shed any light on what's going on here?

 

I'm not super familiar with the display output configuration of the 5510, but it's possible that one of the monitors is connected directly to the NVIDIA GPU and not the Intel GPU.

To check:
* Open Device Manager
* Expand "Monitors" and click once to highlight a monitor
* Select "View -> Devices by connection" from the menu at the top
* The view should change so that you can see which GPU the monitor that you had highlighted is attached to... If you don't see all of your monitors there, repeat with the missing monitor to find its GPU

On the 7510, there is a BIOS setting to have certain external ports handled by the discrete GPU only. I have this disabled, generally I find that things work better if all monitors are being handled by the same GPU, and in a graphics switching configuration that means that they should all be attached to the Intel GPU.
