If they haven't done it by now, I think it's not likely to happen at all, most likely because Intel did not offer "pro"/business versions of 14th-gen CPUs and that is all that Dell offers in these things. We'll have to wait for next year / 15th gen and see what happens. Doesn't seem like a big loss to me. 14th gen and 13th gen are very similar in terms of what performance you can get out of a thermally-constrained laptop, and NVIDIA doesn't have anything new to show either...

Saw this article. https://www.ifixit.com/News/95078/lpcamm2-memory-is-finally-here A new CAMM memory standard has materialized, LPCAMM2, which allows for modular LPDDR5 modules finally. Hopefully, laptop manufacturers actually start using this. (LPDDR chips are more energy efficient than regular DDR chips which you would see on SODIMM modules, and previously LPDDR has only been shipped in soldered-onto-the-motherboard form.)

Precision 7540 & Precision 7740 owner's thread
Aaron44126 replied to SvenC's topic in Pro Max & Precision Mobile Workstation
No, those will fit under the SSD/DIMM and not cause any problem. -
Go to dell.com/support, look up your system model, and go to driver downloads. You should be able to find old BIOS versions in there. Just run the .exe to install. Two gotchas: Occasionally they release a BIOS update and you will see in the release notes that you can't downgrade if you upgrade to this version. It is not always possible to downgrade. Also, in BIOS setup there is an option to block BIOS downgrades, which you might have to disable.

It is attached to a previous post in this thread, check above.

Thoughts... 1. Do a full system shutdown and then turn it on again from a cold boot, if you have not done that yet... That will reset the EC if something about the BIOS update process itself caused it to change fan behavior. 2. Check Task Manager "Details" tab and sort processes by CPU usage. Make sure there isn't a rogue background process gobbling CPU time. (With today's many-core CPUs, even low values in the CPU use % column are concerning. For example, in a system with eight logical cores [4 cores + hyperthreading], 12% CPU use [100% ÷ 8] represents a full core of activity, shouldn't be happening on an idle workload, and would most likely cause the fans to spin up.) 3. It's possible that Dell bungled the fan tables in the latest BIOS update. Wouldn't be the first time. You can roll back to the previous BIOS version and see if it behaves better.

You'll kind of have to try and see. For Dell laptops, the power cable is a bit more than "just a cord", it uses the innermost pin for digital communication with the power adapter and figure out what power levels it supports. You'll get a warning from the BIOS at startup or from a Dell tool at the desktop (if you have it installed) if an unknown or underpowered power adapter is connected, and it will probably throttle CPU speeds in that case. If the system supports USB-C PD then you can skip the barrel adapter and plug it straight into the charger block via USB-C. ...In any case, you might be able to charge it fine if the system is off / sleeping and only have issues if you try to use it with that brick when the system is powered on.

Yes, that's a regular PCIe slot, but there are a couple of caveats: I think WWAN is B-key and WLAN is A/E-key, so you'd need an adapter. There should be space for it since WWAN cards are larger than WLAN cards... There may not be USB hooked up to that slot; if there is not, the Bluetooth part of the WLAN card that you put there will not work.

Medical Emergency and the aftermath. Very interesting way I am living now.
Aaron44126 replied to kojack's topic in Off-Topic
Cornbread is (usually?) made with regular flour so I'd be worried about that — Still, there's probably options for "alternate breads". Anything labeled "gluten free" shouldn't have wheat. ("Gluten free" is a bit more broad than "no wheat" but it would by definition exclude wheat.) So, there's probably some stuff to try there, I've never experimented in that area myself... Even rye bread might be OK, but you'd have to make sure it is really just made from only rye flour and not a mixture of rye and wheat. -
BE201 will definitely not work, it is CNVi and relies on support from the chipset/PCH. If the slot can accept a regular PCIe card then there is a chance that the other cards will work, however that is not guaranteed since Dell is only shipping CNVi cards in that slot. The prior-gen Precision 7X70 didn't even have a slot there, the AX201 was soldered directly to the motherboard, so I had sort of figured that Wi-Fi upgrades wouldn't be happening anymore...

Agree with the above, a lot of people have mild allergies to certain foods or other things (myself included) but there are some cases where it can be really serious. I had a coworker with a nut allergy who had to be super careful about all food (checking packaging / etc. like @kojack mentioned), because having the allergy triggered could lead to a situation where it was hard for him to breathe, which could get dangerous very quick. -
Got another request about this printer driver. It's still here (in my post up above) ... but I can say that I have now finally chucked this printer in the trash. The Samsung lasted a good long time but started to have issues picking up multiple pages at once and getting jammed. Cleaning it out didn't help. That, plus the problem with not being able to use it with newer OS environments (ARM Windows + macOS, with Linux support being spotty as well) meant that it was time for it to go. I replaced it with a brand new Brother black-and-white laser printer (HL-L6200DW) which has been working great.

Precision 7720 GPU upgrade
Aaron44126 replied to jeamn's topic in Pro Max & Precision Mobile Workstation
I believe that this is the case, too. I don't remember the details for each model, but 30-pin for low-res and 40-pin for high-res is common for Dell to do (with the same system/motherboard). If you want to "upgrade" the display panel then you will probably have to swap out the display cable as well. You could possibly use a 30-pin panel with a 40-pin cable, with an adapter, but not the other way around. ...Around this era, they also had a tendency to stuff the webcam cable in with the display cable so that it uses a single connector on the motherboard and splits off inside the display enclosure. -
The mainboard is the same. However, you'll probably need to replace the entire display enclosure (OLED panel has glass or something covering the front) and possibly the display cable as well. The best bet would be to get the display panel + enclosure + cable (+ webcam) all as one pre-assembled part, which is how Dell does it when they are doing a display replacement under warranty with these systems.

1991 had totality through Mexico, Central and South America. I did see a partial one in 1998 (around 30% coverage from where I was). Missed 2017, which was the most recent good one to see from the U.S.; I had a health issue going on at the time that prevented me from thinking about making the trip.

Got a great view a bit south of Indianapolis. Totality of about four minutes and hardly any clouds at all. Never seen one before… Worth the trip.

M4800 Owner's Thread
Aaron44126 replied to unnoticed's topic in Pro Max & Precision Mobile Workstation
I’m not so sure about compatibility, if you plan to use Windows anyway. M6800 has a BIOS conflict with Pascal cards. I’d think it would be the same with M4800. You will get an ACPI.sys BSOD when booting Windows or Windows Setup. Fixing it requires chain loading a pre-boot tool to change some BIOS tables. (Linux boots fine, without any extra work.) It can be avoided with an older “engineering sample” VBIOS, but those have only been discovered for Quadro cards, not GeForce. -
Driving into totality path right now! Hopefully Indiana has enough breaks in cloud cover to get a good view.
-
Haven’t heard about that. I did hear yesterday that you can use something with small holes (I.e. pasta colander, straw hat) and hold it in the sun during the partial eclipse to maybe cast a shadow that will let you see the crescent-shaped sun without using eclipse glasses or having to look at the sun directly. Also doubting that would work in cloudy conditions, though.
-
Still watching the weather, I have a potential spot in Indiana that I'm looking at. Worried about traffic, too. It might not work out.
-
Looks like you are pretty close to the best spot! (Assuming that the weather cooperates... Quick weather search here looks like it may well be fully overcast in that area like I am seeing for Texas.) You should definitely take care when looking directly at the sun. I bought some solar glasses from Amazon some weeks back. They work great, basically producing black vision, can't see anything other than the outline of the sun if you look at it. It is safe to look without glasses for the few minutes when the sun is totally covered if you are in the path of totality. (Looks like your map has color codes indicating how long that is by location.) That is supposed to be a really cool experience but I have never seen it before, though I can imagine how it would be difficult to fully capture what is is like on camera / live stream.
-
Anyone in the U.S. or Mexico going to try to make it? I was going to try to view from Texas, but the weather is looking uncooperative. Thinking there might be a shot to view it from Indiana or maybe Ohio (closer to where I live) if I can just find somewhere where it looks like there will be a break in the cloud cover. Watching weather forecasts keep changing, I know there won't be truly decent cloud coverage predictions until a day or two before...

Precision 7540 & Precision 7740 owner's thread
Aaron44126 replied to SvenC's topic in Pro Max & Precision Mobile Workstation
Yes, the USB ports are powered on even if the system is powered off. I believe there is an option in the BIOS called "USB powershare" which might control this — I just leave it on as that is the preferred behavior for me. (You can actually use the system as a giant USB battery even if the AC adapter is not plugged in, i.e. to charge your phone while traveling.)
