Precision 7530 & Precision 7730 owner's thread

Works for me too, but I am using the notebook with graphics switching enabled.

A point to note: for some magical reason, the idle power on my notebook has dropped to a paltry 4.5 - 5 W (provided any one Adobe CC app is running and minimised). This nets me an incredible 18-20 hours, provided I don't touch the notebook at all. This is a trebling of battery life, and it is testament to what can be achieved.

Under normal use (programming in VS Code, QtSPIM open, a couple tabs in Adobe Reader, dozen tabs in Chrome, and trackpad touched every 30 seconds or so for 2 seconds each), approximately 10%/hour is a typical drain, so 9 hours of actual use is expected.

Much, much better than the 4-5 hours I was getting before I discovered this hack.

 

Miss my E-Port dock :-(

May not be totally fair to compare, as the new docks have to deliver all that bandwidth and power through these tiny USB-C ports, but if one was used to a working e-port, these TB and WD things are a regression...

 

In that case, do you even see the Intel GPU in device manager?
If yes, which driver version do you use for the Intel GPU?

Which Intel graphics driver version do you use?

 

I do see it in devmgmt.

I'm using the Dell driver, because the default Intel driver gives me weird bugs and crashes while launching games.

 

Nope; with graphics switching off, the Intel GPU doesn't show up in Device Manager.
I echo @Ionising_Radiation and recommend using the Dell-provided driver for the Intel GPU. On my M6700 I have gotten strange behavior when using the driver directly from Intel, even when the version number is the same. There appear to be some small tweaks/customizations done by/for Dell. (Intel warns as much when you go directly to them to get a driver.)

 

I'm scrapping the following:

https://www.dell.com/support/driver...Precision Mobile WorkStation&initialload=true

It returns a JSON file with drivers for the specific service tag.

 

I'm using the Dell driver as well. Currently their latest 26.20.100.6911 A09. Is that the same you are using?

 

Just installed 1.11.0 and can confirm FN+up/down for brightness change still working.

I have Optimus active with
Intel UHD 630 driver version 26.20.100.6911 from Dell
Nvidia P3200 quadro driver version 436.30 from Nvidia

 

I rarely run my laptop on battery, but today i noticed cpu freqs never go higher than 2.4 ghz under load.
Anyone knows if this is normal behaviour? I never noticed this with older BIOSes (note that i don't run the very latest BIOS you guys have been talking about, but the one before)

 

Just in case any else runs into some Windows Update troubles:

Enabled C-States seem to prevent the latest Windows 10 update KB4517211 on my 7730. That update came together with an Intel GPU driver update to 26.20.100.7620 this morning. So not sure if both updates are "required" to get into my update problem.

7730 always shut down and rebooted or hang with full speed fans while showing "working on updates" with different percentages between 51 and 84. After a few of those reboot cycles Windows offered repair options. Didn't want to reset my PC, so I rebooted a few times more, but without success.

When I disabled C-states in BIOS, the Windows update succeeded.

Unpleasant start of the day worked out in the end ;-)
