    I updated my NVIDIA driver today to Dell's 512.18, and was able to reproduce this issue. I took the pull request but added some extra logic so that the program can "remember" the GPU name from previous working requests when the GPU was powered on. Here's a test build. I'll do a proper release tomorrow or the next day. There's another bug that I've been sitting on that I want to address, relating to the "Thermal setting" feature. Note that the project has been moved from .NET 5 to .NET 6, so you'll have to install the .NET 6 runtime if you do not have it. https://1drv.ms/u/s!AsIwJHFk4EFdqKJP4MOlZA6NwrWAPg [Edit] Refreshed link, good until 1/1/2023.

    6/21, hmm... Not really surprised about another delay. I placed my order on 6/6 and it was canceled "automatically" (no action on my part) on 6/10. I do not think that Dell is taking orders at this time (they were opened by mistake somehow) but they are giving out quotes, so you can work with a rep to spec out a system and get a price. Planning to get in touch with my rep tomorrow, will see if I get the same date out of him (along with a new quote).

    BIOS setup display/video section might have an option to set the “default” brightness of the built-in display …? (Never seen one of these. My best guess.)
  4. Aaron44126
    #3 = power connector (seems important) #4 = speakers (not USB, just a straight analog audio connection most likely) Maybe first just try to disable webcam in the BIOS and see if that helps you at all. Way easier. Do you see webcam in Device Manager? (Just one more possible hint.)
  5. Aaron44126
    One more. Display cable does indeed have "one" end on the motherboard side and "multiple" ends on the other side. So if you do want to disconnect the webcam, probably best to access the webcam and pull the cable from that end. https://www.ebay.com/itm/255084291259?epid=19030890620 https://i.ebayimg.com/images/g/EycAAOSwkWZhDT5p/s-l1600.jpg

    I found reference that "6" in the image above is the display touchscreen cable (which I believe is USB).
  7. Aaron44126
    Oh, I think there is a toggle in the BIOS setup to disable the webcam as well?
  8. Aaron44126
    Most of the internal USB stuff will have a connection on the motherboard. 1 = touchpad, 2 = keyboard (not sure if these are actually USB or not) 5 = fingerprint reader cable Bluetooth module is built into the WiFi card but attached via USB (something else you can try to remove) If you have the touchscreen display, I believe the "touch" part of that is also USB attached. Not sure how you would disconnect just the webcam. My M6700 has separate cables for the display and the webcam but I think some newer systems bundle them together (on the motherboard side anyway). If you can remove the display bezel, there might be a cable on the webcam module side that you can disconnect. (Not sure how easy it is to remove the display bezel on the XPS-style Precisions. On the 7000-series it is pretty easy to just pry off. It's attached with some plastic tabs and adhesive.)

    It would be hard to fully disable USB in these laptops. It goes a bit beyond the USB ports on the sides — the webcam, Bluetooth module, and fingerprint reader (if you have one) and perhaps other things are attached via internal USB as well. I'm noticing the delay of several seconds between attempts when it tries to query the USB device descriptor there and I'm thinking that yes indeed these may be connected. I've seen the BIOS get hung up on USB stuff, now that I think about it — my Precision 7560 will hang in the BIOS if I have my USB hub connected. (The USB hub has a couple of external optical drives connected to it and also a RCA video import dongle thing. I haven't bothered figuring out which specific device is causing the problem, I just don't connect the hub unless I need something connected to it and it works fine after boot.) ...If you boot into Windows, are you seeing any "USB device descriptor failed" errors if you open up Device Manager?

    A couple of interesting tidbits I gathered from going through the service manual in more detail. Keyboard Unlike prior systems, there is no separate keyboard trim that can be removed to allow for easy access to the keyboard for removal. Swapping out the keyboard now requires removing a huge pile of components, including the heatsink (thus requiring repaste), inner frame, and motherboard, so that you can basically take the keyboard out from the bottom. (Can't even pop the palmrest off to get to the keyboard. Removing the palmrest requires removing the keyboard first!) Now, because there is no RAM under the keyboard, it's less likely that you'll have to remove it... but as the part that you are actually pounding on when using the computer, it could certainly wear out over time. (It's also the part that you can most easily spill sticky stuff on! 😛) I hope this thing is very well engineered. I replaced the keyboard in a Precision M6700 and Precision 7530 just because they stopped registering certain keypresses properly. At my request, Dell shipped me the Precision 7530 keyboard without a tech because it's a "user-replaceable part". I've been contemplating replacing the keyboard in my Precision 7560 because the left alt key is a bit messed up. Anyway, it's rather disappointing that replacing the keyboard now requires so much hassle when that has never been the case before. Yuck yuck yuck. WWAN antennas Here's an interesting one on antennas. In addition to the four WWAN antenna cables that hook directly to the WWAN NGFF card, there are three here that attach directly to the motherboard. Not sure what this is about. The manual refers to the black ones as "WWAN (Darwin) antenna connectors" (don't know what "Darwin" means here) but doesn't say what the green one is.
  11. Aaron44126
    The other thing that I can suggest is to just disconnect the main battery, run on AC power only, and see if that fixes it. I know that involves removing the bottom panel. Batteries have a limited life and while I have not experienced this particular symptom before, I have seen laptops display some very strange behavior when hooked up to a battery that is ready to be EOL (even if they are not running on battery power).
  12. Aaron44126
    This is an odd one for sure... I've had cases where the system lags for no apparent reason that have turned out to be power related. I think that the system "thinks" that it has an underpowered connection and goes to hard throttling mode. Solved by disconnecting the internal battery and PSU and then reconnecting — in a few cases it was actually the PSU's fault (@*%# Delta PSUs) so I had to swap it out. ...But in these cases for me, the lag would persist into Windows. In this case, I think that the first thing I would try would be disabling the NVMe drive in the BIOS (as @Rinconmike recommended) to rule that out. If that "fixes" the problem, I guess consider replacing the drive. (...But a flaky drive would probably also be causing issues in Windows.) The next thing would be to just reset the BIOS to default settings and see if that helps at all. ...But if it doesn't, it could be quite cumbersome to go and put all of the settings back to how you like them. Failing that, I guess we are looking at motherboard replacement. It would be pretty strange if a Linux kernel update kicked off this issue. ...Are you looking at getting Precision 7X70 (I know you've been posting a bit in that thread)? Might just have to hang in there for a month or so 😕. Just try not to reboot ever 😛.

    The WiFi is Intel AX211, which is CNVi — the implementation is split between a discrete WiFi chip and support built into the Alder Lake PCH. (Basically as you say.) Still, they could have put the WiFi card slot on and had the AX211 chip installed on a card in that slot. (Swappable AX211 cards are a thing.) That way it would be possible to upgrade to a card implementing a future version of WiFi (as long as the implementation is all on the card - fully PCIe and didn't rely on the PCH). As it stands, upgrading a Precision 7X70 for WiFi 7 (802.11be) will not be possible (without using a USB dongle or something). That's a first for the Precision 7000 line. Well. I do have a NGFF B-key to E-key adapter which would allow a regular NGFF/PCIe WiFi card to be installed in the WWAN slot. B-key does not pass through USB so the Bluetooth part would not work (but that's less important). When I receive the 7770 I will check and see if a standard NGFF WiFi card will actually fit (physically) this way. (Hooking up the antennas might still be a challenge.) Pretty sure arrow keys are the same on all versions? The keyboard is identical to the one in the Precision 7X50/7X60, in terms of layout at least.
  14. Aaron44126
    Indeed, try to find a version from 2019 and then move up from there. I think that Dell generally expects Windows 10 users to stay current. (That said, I haven't had trouble with this + LTSC 2021.)
  15. Aaron44126
    Disappointing but not unprecedented — I believe with Precision 7X30/7X40 you could not order 4K and WWAN together. Also, with Precision 7X40/7X50/7X60 you could not order IR webcam and WWAN together. Seems like WWAN is bound to cause restrictions... You can always go with a USB WWAN solution, use a WWAN hotspot, or just tether your phone. (Not sure if any USB WWAN solutions also provide a GPS sensor, but the other options definitely wouldn't get you native GPS in the system.)
  16. Aaron44126
    Found some more images that confirm that the WWAN antennas are indeed up in the display enclosure. They are routed up through the right hinge (probably also with the webcam data cable).
  17. Aaron44126
    Looks like there are four antennas going to the WWAN card, but I can't see where they go too in the small image up at the top. @Dell-Mano_G mentioned that WWAN antennas are only included if you buy a system with a WWAN card. In past systems, there has been a variation of the display enclosure depending on whether you get WWAN antennas or not. The WWAN version has a plastic bit at the top and the antennas are housed up there. (See below. Not sure if that is how it is with 7X70, yet.) You can see Wi-Fi antennas (black & white) hooked up to the soldered AX211 chip (...that's probably what that is...), just to the right of the WWAN card in the image above. These connect to the dark "L"-shaped things that you can see on the front/sides of the chassis. Precision 7760 with no WWAN antennas. Precision 7760 with WWAN antennas.
  18. Aaron44126
    It appears that the same system that we saw in 7X60 is present in 7X70 with regards to the "primary" SSD; it gets installed into a little plastic carrier. No thermal pad to draw heat out through the chassis like you have with the other drive slots. (But with DOO fans, this one would presumably get at least a little bit of passive airflow.)
  19. Aaron44126
    Spec sheet specifically mentions vapor chambers (plural). Could the grill things right on top of the CPU and GPU chips be mini vapor chambers?

    Manuals are live. Dell account login required. (Thanks @Rinconmike for the tip.) 7670 - https://prm.dell.com/content/cninv000000000662732/fsm/7670/english/index.html 7770 - https://prm.dell.com/content/cninv000000000662732/fsm/7770/english/index.html If images are broken, go log in at one of the manual sites and then come back here and reload. (I'll work on having them rehosted elsewhere and change the links in a bit.) [Edit] 7770 heatsink. 7770 GPU card. Hard to believe that you can fit 150W 3080Ti in that space, but it doesn't look like there is any room to expand the card size out to the left (fans go there). I was going to say, just two DGFF connections makes it look like this will be PCIe4 ×8 and not ×16. But, they appear to have changed up the DGFF connector and added more pins, so it may well support ×16. The 7760 one looks like this: Forget about using these cards to upgrade an old model Precision. 7770 motherboard. Where's the PCH? What is the DGFF-looking connector that is to the upper left of the CPU for? Also, seems that coin-cell battery connector is on the wrong side of the motherboard again, if I'm interpreting this image right. [Edit 2] 7770 chassis images. [Edit 3] Looks like they went for full integrated Wi-Fi card. I only see a WWAN card slot, and they do not have any directions for removing the WLAN card. That's a bit disappointing. (You could potentially mount a NGFF Wi-Fi card in the WWAN slot, with an adapter, if there is physical clearance for the card+adapter. However, it was previously stated that WWAN antennas are only included if you order a WWAN card, so you'd have to figure out an antenna setup too.) [Edit 4] Switched image hosting, shouldn't have to log in at Dell to see them.

    I can confirm that it's exactly the same file as before.
  22. Aaron44126
    I have this issue sometimes. Kill any instance of nvcplui.exe. Restart service "NVIDIA Display Container LS". It will normally open after that (but it is very slow to do so). I'm also using LTSC 2021 but I have had this issue on-and-off even on regular Windows 10. (Also, using DCH drivers.)
  23. Aaron44126
    Do you have the fingerprint reader that integrates into the power button? I have noticed that in this case, the power button function is disabled while you are at the lock screen. I guess it is to keep you from accidentally pressing it while trying to just have your fingerprint scanned. The power button works when the system is unlocked.
  24. Aaron44126
    This was announced after the "regular" Precision 5470 was already on sale... Doesn't seem to have actually released yet.
  25. Aaron44126
    Yeah, they do this every month. The preview update "fixes" will be rolled into the upcoming (required / non-preview) Patch Tuesday update. The Bing Service 2.0 update just adds SHA2 support to existing Bing stuff. (They could definitely have done well to properly explain that to people.)
