I'm worried a bit that in the attached sparse documentation it is mentioned that customer serviceable units are only as power adapter, base cover assembly, memory module, memory module bracket, solid state drive and power cord. Isn't battery sort of not user replaceable?

How can you define my "productivity" on the basis of the laptop only with no individual data about myself? How can a 30GB presumably lacking in an SSD with ~890GB free space "degrade my productivity"? Is forgetting about crafting professional artisanal code on that cramped toy setup is just your personal opinion skewed by Dunning-Kruger effect or you can provide some arguments of a logical or physical type?

Oh, with AI game players, can't you just insert a print statement in code to simultaneously log all weights' changes and their accompanying changes in performance etc in a file and get another AI like some multi-parameter regression to search for correlations in it?

Well, you actually do want to turn the clock in reverse. That's a hallmark of the highest so far methodology standard in science: if you want to position that you gained a full understanding of an object, you need to be able to reverse engineer it both in space and time. Many cancers contain senescence associated secretory phenotype (SASP) and senolytic drugs have been researched to be able to neutralize cancer cells as well as senescent cells.

You do want to turn the clock in reverse, only maybe not the whole way back to the embryonic state, but a couple of formal years or decades back to reset the epigenome, and this is exactly what David Sinclair, Vittorio Sebastiano and many others are undertaking now.

There is a recommendation from one Ukrainian doctor on Youtube to take senolytics for a 1 week per month rather than continuously, because apparently it takes ~20 days for a new generation of senescent cells to form. But David Sinclair, as evident from his Lifespan podcast, seemed to take a couple of senotylics on a more continuous basis, for months probably.

Basically I do not want to return it. I knew it will have 8GB of soldered RAM, but I found this article [1], which explained some benefits of soldered RAM. And elswhere on some gaming forum it was mentioned that if soldered RAM is faulty, it will be evident in he first month of usage. I'd like to install Ubuntu in dual boot with Windows as soon as possible, but in recommendations on testing new laptops there is a memory test. If it still worked fine (no blue screens etc), should I run the memory test to test the soldered RAM or the soldered RAM functionality will be more evident under some "natural" loads like 3d modelling software and compute intensive/parallel tasks?

So why did you mentioned "And forget about crafting professional artisanal code on that cramped toy setup."? I will be using Windows in dual boot with Ubuntu, and if VM allows to activate Windows from a VM, I may remove Windows completely from this laptop.

WIndows shows 930GB total SSD capacity, with 35GB used by Windows. But the remaining free space seems sufficient for at least the 2 years of warranty.

I am worried a bit that even under rather small load like opening folders and checking sound/video palyback, the vent grid on the bottom of this new E14 (which doesn't have a vent grid in the side) gets rather warm, so I need to constantly use the external cooling pad.

P.S. Ok, my reaction to this is 95% off-base and a bad habit to get into, but the implicit on-site idiotic circus that led me to buying from this vendor may overweigh by the remaining 5%, so a deeper awareness can also benefit to everyone.

Why this RAM/SSD/CPU (AMD Ryzen 3 4300U 4 core, 4 threads) setup in E14 is not enough for professional artisanal code? Can it be sufficient for dual booting Windows10/Ubuntu 22.04 and learning the relevant coding skills to at least 80%? Or do you need Linux only installed without dual boot?

I want to believe this is true, maybe Ubuntu in dual boot will show more info on RAM and SSD.

How can 16GB of RAM have 15.2GB usable RAM? (there probably is 8 GB soldered RAM)

What's funny, this lousy vendor was recommended to me by another lousy PC repair/retail shop (who has got an Facebook ad with this vendor) recommended by a 10x lousier CS teacher who teaches C++ in Windows.

Yes, it's always lower than claimed, but the whole SSD capacity shown by Windows is 930GB. Or is it too much of a great deal for 550 euros?

>>Pragmatically:

Doing tasks on HackerRank should be fine regarding these subjects. But thanks for the keywords.

Regarding "my own original interpretation of (some of) CS foundations and concepts", it's not as much "a point of pride", but rather lack of context here. My interest is actually in the intersection of several fields with CS, if I were to choose I'd choose CS & electrical engineering and apparent confidence comes mainly from abstractions of some underlying physics.

Any time I share anything, there is a surge in various elements of the ongoing idiotic circus, this is why I really don't care.

What do you mean by a "not trivial" website? As I am focusing currently on Python, one of my benchmarks is talkpython.fm, which I know is written in Python. Is this website trivial or not?

I know, I mentioned that I am planning to build a website(s) with/for my portfolio of projects and tasks demonstrating various skills, but he keeps reiterating that I need to attend some locally taught courses to get a certificate.

RAM pretty much never dies. It's either faulty on arrival or lasts the lifetime of the device. https://gamefaqs.gamespot.com/boards/916373-pc/71723683

I've just seen on google (on askubuntu) that it can be possible to make Ubuntu ignore soldered RAM and use the socketed RAM instead.

https://askubuntu.com/questions/1428808/can-i-disable-one-sl...

"There isn't anyway to disable RAM as far as I know, but there is a way to have Ubuntu ignore the bad RAM, but you need to know the addresses of the RAM in question."

Can someone evaluate the plausibility of this?

If I connect such SSD externally via usb to another laptop and choose in its BIOS settings to boot from USB, will the OS on this SSD boot up as if it were inserted into this another laptop?

I found the ThinkPad L14 G1 14 FHD 4650U 8GB 256SSD EN W10Pro at ~700$ locally, it's a bit less in memory to run dual boot. So there should be really good reasons to abandon soldered RAM in E14. I asked a person from a PC repair shop, whether he potentially could perform the same on system board, as this guy on DEll XPS from the link above. And he told, that theoretically it is possible to rewire the resistors on board so that BIOS won't detect soldered RAM and use only the insertable RAM, but there's the risk of overheating of the board and making the laptop not operational.

Though I can't see enough logic here for board overheating, if you leave the soldered RAM in the board and only resolder the Serial Prescence Detect module resistors in specific points on board. The board could overheat if you resolder the RAMs themsleves and not the small resistors.

Why E > L? E series with AMD CPU seems to come with partially soldered RAM, while L series with insertable only RAM.

Yes, 1) - in case the onboard RAM gets malfunctioning. And you may not want upgrade it, but to just leave in the board and make BIOS use only the soldered RAM.

Resoldering a couple of resistors on the board seems like not a big deal to make BIOS forget the soldered RAM. As I am planning to buy a laptop with partially soldered RAM, I want to ensure the possibility of dealing with it successfully.

I asked a person from a PC repair shop regarding diy rewiring the board in E14 to ignore the soldered RAM, and he told that it is theoretically possible, but there the risk of overheating the board.

On the other hand, basing on this Dell laptop diy rewiring case, if soldering all Serial Prescence Detect module resistors to position 0 can make BIOS to expect zero soldered RAM and switch to socketed RAM , such soldering seems doable moderately easily by yourself.

>>the soldered RAM limits the amount of total RAM that can run in dual channel mode

Can it affect running 3d modelling software, like CADs or Blender, on an integrated graphics card with shared (dynamic) memory?

As mentioned here [1], at least on a Dell XPS laptop while diy upgrading soldered RAM, it is necessary to resolder a resistor from 1 to 0 position on the board to tell BIOS what RAM to expect.

Maybe for E14 thinkpads it is also possible to perform a similar thing, to diy rewire the board to ignore the malfunctioning soldered RAM and use the socketed RAM instead. But how to get all the original thinkpad system board schematics?

I also like the T series more, and this renewed T480 would have approx. the same functionality. One issue is that is comes with Windows 10 and I should probably need to check the Windows itself that it's clean etc.

It may be possible to use conductive ink to place the necessary connective paths on the board to the inserted RAM.

According to [1], you need to resolder only 1 resistor to tell BIOS that the soldered RAM is 16GB upgraded (in this case of upgrading the 8GB of soldered RAM to 16 on a Dell XPS13). Can it be assumed in a similar vein, that if E14 soldered RAM fails sometime, and you may only want to block it from usage and leave in the system board, so you may only need to fiddle with resoldering some resistors? Thou it currently seems like no, as I suppose the system board won't work at all without any working soldered RAM. So there need to be a way to inform the system board to not use soldered RAM and use inserted RAM.

[1] https://hackaday.com/2021/11/24/you-cant-upgrade-soldered-on...

There are 8 GB soldered and 8 GB insertable on-slot in E14. The most idiotic thing is that if soldered RAM fails, the system board won't work, even if the other 8GB inserted RAM are fine and everything else on the board is fine.

I suspect that solder joints may also be affected by heat. Though, of course, I won't be checking it in a microwave oven.

Is it more or less suitable to suppose that if during the 2 year warranty for a new E14 thinkpad its soldered RAM works fine, so there are no essential manufacturing defects in it and it should be ok in the long run?

But I am also worried (as a theoretical possibility) whether somewhat above-the-normal external magnetic or electric fields won't affect the soldered RAM too adversely.

>> Many TrackPoint users are frustrated with Lenovo's decision to solder RAM in ThinkPads

It would be useful to see some statistics about how many soldered RAM actually malfunction due to manufacture defect. As I mentioned, a person from a PC repair shop told he didn't encounter any issues with soldered RAM on Lenovo Thinkpad's specifically.

The local vendor doesn't know how old these T480 are, it would be clear on place, upon order delivery. The supplier provides 2 year warranty for this refurbished Thinkpad T480 and a 6 month warranty for the battery. Given these warranties it seems not to be very old.
