After seeing it hyped up for a few months now, the Qualcomm Snapdragon X Elite SOC is starting to show up in laptops. There were many announcements today, and these systems will start shipping next month. Microsoft Surface Laptop and Surface Pro https://blogs.windows.com/devices/2024/05/20/introducing-the-ultimate-copilot-pcs-the-all-new-surface-pro-and-surface-laptop/ Dell XPS 13 and Inspiron 14 / 14 Plus, and some Latitude systems https://www.theverge.com/2024/5/20/24160859/dell-qualcomm-snapdragon-x-elite-plus-xps-laptops More coming, from Acer, HP, Lenovo https://www.pcmag.com/news/meet-the-snapdragon-x-elite-starting-lineup-from-acer-dell-hp-and-lenovo Interested to see some real-world performance tests. These are obviously mid-range systems and not trying (yet?) to replace high-performance systems like mobile workstations, high-end gaming systems, or what passes for DTRs these days. Still, they show competitive single-threaded performance against Intel Core 7 Ultra and Apple M3, while boasting efficiency and battery life closer to what one would expect from the MacBook Air. There's a lot on the technical side that I'm interested to see how it unfolds: These systems will all be running Windows on ARM, which has until now been pretty uncommon to see "in the wild". Will Microsoft relax their failed attempt to control the Windows ARM ecosystem and start allowing, say, ISO downloads so users can do a self-install? Emulation of x86/x64 apps on ARM Windows is not in terrible state, but how many software makers will start offering native ARM builds of their software for best performance? Both Chrome and Opera shipped ARM-based versions of their browsers for the first time in the past few weeks. ...I've been running the ARM Windows Firefox build in a VM for almost a year. Qualcomm says these things are decent at gaming. Well, eh, that's a stretch. They have a demo of Control being played at 1080p/30FPS. (You can play it on a high-spec MacBook Pro — that is, also an ARM system — through CrossOver, at 1440p/60.) But, more and more games are leveraging AVX instructions and requiring CPUs that support them. Microsoft doesn't support AVX in their emulation layer (yet?), so such games have no hope at all of running on ARM systems. Will game devs relax this requirement and offer builds that work without AVX, or ARM-specific builds? Or will Microsoft add AVX support to their emulation layer? Or will gamers who want to play on the go just have to navigate a confusing compatibility landscape? Similarly, low-level software that integrates with the kernel (anti-cheat, security software, backup software, etc.) won't work through the emulation layer and needs an actual ARM build. Haven't seen much traction in this area yet, but that seems likely to change as ARM laptops start being dumped out onto the market over the next few months, including in business settings. Will anyone besides Qualcomm make ARM SOCs to try to compete in this space? There have been rumors that both NVIDIA and AMD are interested in launching SOCs to run ARM-based Windows in the next year or two. NVIDIA has had some success with their ARM-based Tegra SOC (see: Nintendo Switch). Will anyone target the high-performance space? (Qualcomm's marketing material shows how well their SOC holds up against Apple M3, but doesn't mention M3 Pro or M3 Max.) If there's real competition here, will Intel even be able to keep up, if it becomes clear that you get a "better laptop experience" on a non-Intel system? (Thinking about things like the noise, heat, and battery life that you experience for the same level of performance.) We may well have a situation where it is rare to see Intel-based laptops by like 2030 (at least for low & mid-range systems).

Subsystem ID will never match when you're doing a flash of an "unsupported GPU" in a laptop. The subsystem ID is actually determined by the motherboard of the system that you put the GPU in, so it is expected that it will not match. You'll need to pass the flag to nvflash to ignore that. (Something like -overridesub I think.) As for the board ID being wrong, I'm not sure about that and if it would be "safe" to try and force it.

That would be enabling graphics switching so that the Intel GPU drives the laptop built-in display. (No idea if Coreboot allows that in this system.) Also, back up your original vBIOS before flashing just in case.

In Windows, go to the Power Options control panel. Click "Choose what the power buttons do" on the left. At the bottom of this section, uncheck the option for "turn on fast startup". Then, see if your shutdown behaves properly.

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.)

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.

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...

As a note, even if you disable "capsule updates" in BIOS setup to prevent Windows Update from updating the BIOS (and I definitely recommend having that disabled), installing a BIOS update via the downloadable .exe file from within Windows still works.

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.

They finally posted another BIOS update. Let's see if it really fixes the performance issues introduced by 1.18... https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=PT1RT

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.

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.

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.
