Thank you very much, @Aaron44126, your advice and insights are priceless! 🤗

Made a fresh Windows 10 installation to my M6800 the other day, and one of my goals was to minimize the use of hardware-specific software when installing its drivers, coz I don't fancy ending up with a bunch of programs that will potentially hog my system, plus they'll possibly be checking for updates periodically — as if we didn't have enough of them programs doing so already. Anyhow, I had downloaded all applicable driver software for my tag number from the Dell site, and extracted any driver that was easy to do (i.e. simply by unzipping the executable or by selecting the extract-only option wherever it was present). I then used DISM to load those .cat, .inf, .sys etc files (that were specific to Win10 x64 that I'd be using, so I didn't add additional drivers for x86) to install.wim before launching the installation; its report stated that 44 drivers were added in total. When the Win10 installation concluded, with the Windows out of the box (having aforementioned install.wim with strapped drivers — but it also may very well be just what is included with 21H2) installation, there already were Realtek's HD Audio driver and Audio COM components showing in 'Programs and Features'; the Airplane Mode and Bluetooth worked as intended; and there were the Intel Graphics cpl as well as the Dell Audio cpl present in the taskbar. Moreover, I had 4 exclamation marks in Device Manager; two of them were related to Intel's Management Engine components, and the remaining two to Dell's ControlVault components (this M6800 has a fingerprint sensor and the NFC thingy). Okay then, for Intel ME it's a straightforward setup executable that also installs a program showing 'Intel Management and Security status'; for ControlVault one gets presented with a selection of components to install (Credential Vault USB driver, Credential Vault WBF USB driver, USHWmiProvider, TPM, and NFC driver), so one can customize what exactly wants be added. Naturally said programs also get added in 'Programs and Features'. So, now I'm facing the question what should I do regarding all other programs provided by Dell — am I to install them or not? What is the expected utility value to receive out of them, or are any of them indispensable to begin with? Obviously if one wants to have NView and/or any of they other NVIDIA-related stuff, one will need to install them (personally I don't thing they relate to me use case, though, as I do zero gaming). Intel Graphics also seem to have an app connected to them, I'm not entirely sure it's something on top of that cpl I see at the taskbar. I also see that this M6800 had something called Maxx Audio from the factory, but I have no idea whether I need it or not. I believe Dell's package for the touchpad also installs some app for its settings, bu I can't remember ever using any touchpad app in my whole life — traditionally it's been yet another zero-utility icon in the taskbar. I see among Dell's offerings for this laptop an 'Intel Bluetooth.msi', but I fail to grasp whether it provides anything of substance above the standard Windows settings. Plus there's also an app, from my understanding, for Airplane Mode as well; not convinced I need that, either. Intel's RST I'm sure won't be needed coz I'm not gonna use RAID, but I'm okay to be corrected if I'm wrong there. And I kinda get it that, in case I want data protection features, I'll have to install those STsetup and DDSSetup guys. Now for the actual questions (but of course you can also comment on or correct my above assumptions): Dell Command | Update — do I need it? Dell Command | Power Management — is it worth it, do I need it? Dell Digital Delivery app — do I have to install this?

Couldn't find any solid info on that online, asked at the Dell forums but to no avail, so here goes: I have a Precision M6800 that did not come with a WWAN but I want to add one to it. Minimum cellular networks compatibility should be the EMEA region, but the wider (i.e., the more comprehensive) the better. Anyhow, I said to myself okay let's get DW5809e for this mission, but from what I see it comes under (at least) two discreet Dell p/n's: namely, 0453K0 and 0K2W44. So, what's the difference between those two, and which one should I choose? Thank you very much in advance! 😊

Thank you, @ruboj, I'll sure do!

Thanks, @Chalybion! Actually that'll be my first attempt in undervolting, so I'm gonna need any resources available, for me to get help and guidance. 😊

I use three laptops with the following configurations (I'm starting a single thread so that I won't need to post in three different owners' threads at once): Precision 7750, Core i9-10885H & Quadro RTX 5000 Precision 7740, Xeon E-2276M & Quadro RTX 3000 Precision M6800, Core i7-4800MQ & Quadro K3100M My questions are as follows: Should I attempt undervolting them? Is it possible to find unlocked BIOS's for these? As far as the 7740 is concerned, will I gain anything from fiddling with the dGPU vBIOS? In general, are there any meaningful upgrade paths for my laptops? Thank you very much in advance! 🥹

Does anyone know the p/n for WWAN card in Precision 7740, along with all other needed parts for installing it in a non-WWAN 7740?

Does anyhow know what is the change log from subj. BIOS v.1.05.18 to v.1.05.19? I couldn't find any reference for it. BIOS v.1.05.19 seems to be available for download from Schenker for XMG P506/P706, which is exactly the non-branded Clevo that I personally own (i.e., P651RE), but I don't know whether it'd be wise to flash it to my laptop or not, since it isn't actually an XMG. Other laptops based on the same BIOS that I've checked (Sager NP8657/NP8677 and Eurocom M5 Pro / M7 Pro) do not offer a BIOS download in their respective pages (as a matter of fact, Eurocom's page leads to nowhere; the Sager ones still work for other drivers), in order for me to see what was the latest BIOS version for them. And, apart from XMG's v.1.05.19, I didn't notice the existence of any even later BIOS version for Clevo P65xRE/P670xRE. Any help would be greatly appreciated. 😊
