    It’s too high, and the Graphics score approaches nearly 23000 (almost 2x the performance of the P3200)... Because that person was using a second eGPU, the RTX 2080 Ti, to run the test:

    Clearly 3DMark’s hardware detection is pretty buggy, because it doesn’t detect the correct VRAM for the P3200, and the clocks are swapped.

    If you do coding, you'd be in hell. I never even tried using this thing for graphics -- I couldn't manage to finish basic set-up. Installed my browsers, chat, logged into some sensitive accounts (yet another round of password-changing), and couldn't get any further because nothing on that screen is readable.

    I double-checked the German review -- https://www.notebookcheck.net/Dell-...Quadro-P3200-Workstation-Review.346631.0.html -- and if you squint, PremierColor's telling them the same thing: week 36, 2015.

    So far that's the only date I've seen; I think I dredged up one complaint from a buyer about a 2014 screen in a 2015 machine, but no details beyond that.

    It looks like this is a firmware issue; the only way to get a date/serial number will be cracking the lid open and seeing if Sharp labeled these things. (Dell rep tried to claim the serial number was a Dell trade secret. SMH.)

    Ah yes, mystery solved then. I did wonder about how he would have managed to get the device to cope with double the power draw that one assumes he would require to hit that score.
    Quick question for anyone who's swapped their screen panels, - which one would you say is the best 144hz panel to go for right now?
    Also, looking up my display ID seems to indicate its a 30 pin screen, does that sound correct to anyone who's upgraded their 45% gamut panels?

    Thanks Aaron, this is great. Quick question - is there a way to control fan speed directly via your utility / from CLI? Was thinking of doing a quick powershell script to avoid having to mess around with speedfan.

    The utility does allow you to set the fan level from the CLI but only for setting it to a fixed level. There is no support for, say, measuring the temperature and reacting based on that.
    Do note that the max fan speed achievable with this method is actually not quite as fast as the max fan speed that the system will kick up to if left to run on its own. There is discussion about this in the thread.

    Thanks Aaron, using DellFanCMD I've managed to push my CB15 score to 1356, which seems pretty decent:

    Hello everyone,

    Following-up with this issue, I got my system board as well as dGPU replaced. The issue was fixed, but after the technician left, I also left for home and when I got home, the dGPU was no longer present in the system. This led me to believe that the issue lies with some cable (possibly the beam connectors or the DGFF Cable).

    I called Dell again and asked them to take my laptop to their lab for proper fixing this time. That was 3 weeks ago. This Monday, I received an e-mail that I have a new order placed. That means for replacement of 1 DGFF Cable and 3 Beam connector cables they are replacing the whole system. Weird, but it's ok. I tried to ask them to make sure that this time, the replacement will come with Bluetooth enabled.

    After getting bounced in-between 3 different business units (As everyone was complaining that they don't have access to the order), I realized that I had an e-mail from someone about the order. It was the person who created it. After several e-mail exchanges, apparently the Bluetooth was supposed to be sorted out.

    However, today, after some more e-mails exchanged, not only the Bluetooth issue should now be gone, but there is a new order placed and they are replacing my 7730 with a new 7740 at no extra cost. Yes, you read that right. It has roughly the same configuration. Still 4k display, 97Whr battery, keyboard and still 64 GB RAM ECC

    Where it differs is the new Intel Wi-Fi card which supports Wi-Fi 6 standard now, there's an Intel Xeon E-2276M (6-Core, 4.7GHz, 12MB Cache) instead of E-2186M (6-Core, 4.8GHz, 12MB Cache) and it includes the new NVidia Quadro RTX 5000.

    This is going to be interesting. I just hope this will be solved.

    Hey Ionising_Radiation, quick question - do you get this battery life with dGPU disabled or is dGPU still available to be used if needed? Do external screens work ok? On my last mess around with Ubuntu on my previous laptop i was doubling the battery life by killing off dGPU using acpi_call method, the only problem was that i couldn't get any external screens to work as on that machine HDMI and DP were all routed via dGPU.

    Currently testing linux Manjaro, had to disable WIFI N band to have a useable WIFI connection and am currently struggling with 2 issues:
    - battery life is not great when compared to Windows 10, minimum CPU power draw only goes as low as 3.5w (around -13w total), yielding maximum idle time of around 6 hours vs minimum 0.4w CPU and around -9w -10w total on Win 10 . This is with GPU disabled via acpi_call (otherwise usage is around 4w higher)
    - running powertop --auto-tune seems to cause my USB mouse to keep freezing until I reboot the machine.
    Has anyone here tried Manjaro and if so have you managed to improve battery life, whilst keeping USB devices working ok? Would love to have a lightweight linux, gui and battery friendly dual boot option on this laptop.

    Hi @arcticjoe.

    I actually haven't figured out the quirks of Linux at all, and I'm sticking to Windows for the time being, as Arch has given me a lot of headaches (primarily of my own making). pacman -Syu doesn't even work, and I am considering formatting the drive (save the UEFI partition), and reinstalling Arch. Hence, I can't really help you with the battery thing as of now.

    @Soromeister,

    Glad your issue has been resolved. I hope your 7740 works well; feel free to discuss it over at the 7540/7740 owners' thread! :)
