Precision 7560 & 7760 Owners' Thread

Thanks mate

 

I don't see the bios update available in Dell Command...

 

it has not showed up on my command update either yet, but is on the download website. Last time I did in manually. I suspended bitlocker, then ran the exe file update. I have not had the chance to run this new one yet

 

I can confirm that manually suspending BitLocker is not necessary. The BIOS update .exe file has a checkbox selected by default to suspend BitLocker for you before the reboot. This worked fine for me, I did not have to enter my BitLocker recovery key after the flash.

 

I just started having a new issue myself -- after a reboot/cold boot, my laptop screen does not come on but the two external monitors attached do. If I unplug one of the externals and plug it back in the laptop screen comes back on. Anyone else having this issue?

 

When you have this issue, go check:
Does the laptop screen appear in Device Manager under "Monitors"? Does it appear in Settings → System → Display?
If it does then I'd say this is a Windows or GPU driver issue, just not remembering the screen configuration correctly. Maybe you can reactivate it from Settings → System → Display or with Win+P instead of disconnecting/reconnecting a display cable and maybe that would "stick" better.
If it does not then it seems to be more of a system issue where it thinks that the display is disconnected, or the laptop lid is shut? That would seem more unusual to me...

 

I updated the 7760 BIOS to 1.4.0 and all seems fine. Took around 5 minutes. I updated by downloading from the support site.

 

Right, it does show up in the Display Properties dialog but the screen is black. Even if I switch the laptop to use the built in display to be the main display it does not come back on. When this first started a few weeks ago it was more intermittent and subsequent reboot fixed it, now it does not. Am using the straight NVIDIA driver (not the DELL one) 471.68.

I tried the Display settings too where I would, say, change the resolution or the refresh rate, to no avail.

 

Hmm. How are your external displays connected? Is hybrid graphics enabled?

Anyway, my setup is:
* Optimus / hybrid graphics OFF
* NVIDIA RTX A2000 w/ driver version 463.02 (from Dell)
* External 27" 4K monitor connected via mDP on the back of the system
I do not have an issue with the internal display powering on after reboot.

 

One is HDMI and one is USB-C, exact same set up I had on my 7740 which worked/s flawlessly. Hybrid gfx is off. Docking gfx is off.

EDIT: I know the laptop is 'seeing' it because all of the icons on the other two mionitors are in their usual places. If the built in monitor was actually off all of the icons on that desktop would be on another monitor.

EDIT 2: I'm actually using the HDMI and the mDSP, not USB-C.
