Precision 7710 Owner's Thread

problems with one of our two 7710 waking from SLEEP for past two weeks.

If we close the lid on my co-workers 7710 and put it to sleep (LED on front "breaths" on and off indicating in sleep), when we open the lid instead of wakeing it reboots after about 10 seconds of no activity (during that 10 seconds there is blank screen with no backlight, keyboard doesn't light up, no drive LED activity).

It doesn't appear to be related to the e-port dock because I can replicate it without using the dock

Event viewer shows this generic error:

"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."​

It is a few revisions behind my in terms of BIOS, drivers. His uses ECC RAM where mine does not (they are otherwise same in terms of hardware). There is a RAM setting in BIOS that is not in mine that I think is there because he has ECC. I may try disabling that option on his. I'm wondering if sleep is having trouble with a bad DIMM. This week I'll update his to the same versions of BIOS mine is at, along with Intel and Nvidia drivers, etc.

Could it be a RAM issue considering that is where SLEEP retains everything? I've experienced odd things in the past relating to displays not turning on when waking from sleep. That was related to Intel Optimus though and I think is different issue.

After we resolve this I'll post what we did.

Thanks

 

Also, is there a sleep file or folder directory in Windows that I could delete or empty to maybe clear any corruption in a sleep file? I know of a hibernate file but wondering if similar folder or file for sleep that we could try clearing.

 

The hibernate file is where the contents of memory are written to when the system is powered off. There is no corresponding sleep file as the system remains powered on to keep memory active while it is "sleeping".
(In the past for me, issues relating to sleep have generally been driver related, but difficult to diagnose.)

 

His laptop awoke from sleep when he opened the lid to it this morning. Thats good, just seems weird and inconsistent. He doesn't let me take his laptop from him more than 10 minutes at a time to investigate, lol. But maybe he had a driver updated or something the night before via windows. I'm going to backup his system and update his drivers and BIOS over the weekend when he's not using it. Thanks.

 

Does anybody have a 7710 that was recently built with the newer SHARP UDH screen?
I had a 7710 in which dell replaced it with a new build, which came with the newer SHARP displays, but am having an issue. When switchable graphics is turned OFF and the computer running only on the M4000M dGPU, I have a line of hot/stuck pixels at the bottom of the screen. It only appears over objects of color. You cannot see it if the image behind it is black or white or if you Windows taskbar is in the way.

Here is a photo: https://www.screencast.com/t/TvFCDrLv1Ij (You can see it is yellow over red backgrounds and red over blue backgrounds. I already had the display replaced twice and it only happens with the SHARP displays).

 

@MustangChris04
You've probably tried removing the nvidia driver completely and reinstalling it (versus overlaying existing version)? Have you tried different versions of driver with same result? I have auo109b rather than sharp though. I bring it up because I had weird issue with win10 taskbar and nvidia driver. I was basically trying to update from an earlier version to Dell certified version at the time. After overlaying (rather than clean install) of the driver the taskbar would only appear cut in half horizontally. It wasn't until I completely removed the driver and installed again that problem disappeared.

 

This issue occurs within the BIOS and system diagnostics, so it isn't a driver related issue within Windows. Although the taskbar being cutoff has been seen on my old 7710. I believe when the dGPU is disabled or not the correct driver installed the bottom of the screen gets cutoff when switchable graphics is enabled and the dGPU is disabled within device manager.

 

ah yes, you are correct on the symptoms I was having and the circumstances regarding taskbar cutoff.

For your issue with the thin red line, does it sound like system bios or video bios to you? If you get display replaced again can you request specifically from Dell for the AUO109B instead of the Sharp UHD?

 

What is the model number of your SHARP screen? Is it SHP145E? Did you find it has PWM issue under 30% brightness level?
Mine is with a AUO B173ZAN though, if I do not install the intel graphic driver, half the task bar at the bottom of the screen can not be displayed. Guess this is a common problem for AUO screen.
Guess your problem is a software or BIOS issue. Perhaps in the next version of BIOS the problem will be solved.

 

I think it is a video bios or an issue with the M4000M, as the screen has already been replaced several times. I could not specify a specific replacement. I sent it to the ProSupport Plus Advanced Resolution Center on Friday and received the machine back today. They replaced the LCD bezel again and the issue is still obviously present!

The SHARP display is DP/N 0CK7T7 and it shows model LQ173D1JW31. It is not a software problem, as the issue occurs in the BIOS and diagnostics screen.

I haven't noticed any issues at low brightness levels. Could you explain further what issue you are talking about when the brightness is under 30%? If you do not install the intel graphics driver, you will always have issues with the bottom of the screen not being displayed. You either need to have the intel graphics drivers properly installed (because the internal display is handled by intel graphics) or disable switchable graphics to have the dGPU handle all the graphics.
