Librem 14: Review and Comparison to Librem 13

By your rationale, it could also be nuclear orbit launch codes, or the recipe to the Colonel’s finger lickin’ chicken, in which case it certainly isn’t “backdoor” code either.

If you don’t know what it is, then you can’t label it. Therefore attempting to is absolutely not accurate. I don’t see how I’d need to work at Intel to know this.

Hasn’t it been revealed to be running Minix? So we would have parts of the source. Maybe that helps during reverse engineering.

Maybe it is a garage door with a remote control?

Or a chute to a garbage bin? (You’d have to crawl up to get in.)

Yes and no.

Unless @dom0 works for Intel, he can’t say with certainty that it is a backdoor. By the same token @MrChromebox can’t say that it is not a backdoor.

What I actually wrote in respect of my own opinion: It may be a backdoor. It may not be a backdoor. If it isn’t a backdoor, it must surely be a good place to put one.

The OP and I are by no means the only people in the world with an interest in having secure computers who have expressed concern about the Intel ME backdoor (in quotes).

We shouldn’t have to put up with Intel’s crap, which goes against everything open source, auditable, verifiable. I am more than happy for people to write “Intel ME backdoor”.

I have never seen anything remotely approaching a credible explanation for why an Intel CPU even needs the Intel ME. Intel has provided only weasel words on the general subjects of the Intel ME backdoor or the purpose of the Intel ME. Intel appears to be making it more and more difficult to tame the Intel ME.

Intel doesn’t have anything to hide, does it?

Is the bluetooth driver opensource? I’m still trying to fix this up under my non-pure os distro.

nice! I face similar issue on my Librem 15v3.

Is this due to hardware update on the Librem 14? If so, anyone knows if it is possible to upgrade the wifi card on the librem15/13 to that used on the librem14?

Woohoo, this is something I had requested in my review of the Librem15v3. thank you @nicole.faerber.

that’s a great addition, gives more flexibility to upgrade.

Question:
One of the requests I had for future librem was to add a protruding edge on the left/right arrow keys to find them without looking at the keyboard, are these available on the librem14?

I believe that the answer to that is “no” i.e. L14 has same WiFi card as L13 / L15. So no upgrade option for you there, unfortunately.

It would be interesting to know therefore whether this finding (of improved WiFi) is universal and, if so, why. One could speculate on better card positioning, less shielding, better antenna, different interface parameters, … but that’s just speculation.

By all means, create a company, fabricate your own CPU, get Mainboard manufacturers to support it, and develop all the firmware and drivers for it.

Because that’s the only way you don’t have to put up with Intel’s crap. Welcome to reality.

I didn’t say it definitively wasn’t - I said it wasn’t accurate to label the ME firmware as backdoor code.

The ME is designed to allow remote access/control via an Intel Wifi or ethernet module. That’s a primary function, not a hidden backdoor. It’s also not a feature present in the consumer (vs corporate) ME firmware shipped on Librem devices, and also not a concern given that Librem devices don’t use Intel networking hardware.

there’s one on the down arrow key, so you can easily go left/right from there

I have to admit, I’m still trying to get used to the right shift key location. I am constantly hitting the page up key instead. Matter of getting used to it, muscle memorization as it were. But I would reverse the two if given the choice :wink:
I will also mention the “A” key does not always work when hit, as others have mentioned, but it’s intermittent, so I will perhaps blame inconsistencies in how I touch it, but it doesn’t happen with any other key. Just an FYI.

If only that were a verifiable statement …

(Let’s put WiFi to one side for the moment) As long as you don’t connect the built-in ethernet to anything (and hence you would need to have a separate ethernet controller for your use in most use cases), one might assume that the Intel ME firmware won’t be a network backdoor. I don’t know of any technical reason why the Intel ME firmware couldn’t sniff out alternative ethernet controllers to use and start using the alternative instead of the built-in.

This link suggests it was “over 92.6%”.

that post is about the 5th-gen Librem 13v1/15v2. the OP was discussing the 13v4, which uses a 7th-gen SoC, and a newer ME engine/firmware which cannot have nearly as much removed from the firmware

good speculation points! :slight_smile:

you mean to say that the down arrow key has a protruding bevel or something of the sort to feel it? Like the ‘F’ and ‘J’ keys ?

correct, exact same raised bevel

I just bought a 60W USB-C laptop charger, and now I realize that I was wrong about the USB-C ports. The USB-C flash drive I used to test how recessed the ports are on the laptops makes it seem like it is not going all the way into the laptop port, but that is actually because of the design of the flash drive, not the laptop. Using the USB-C cable that came with the laptop charger, I see that the Librem 14 USB-C ports are fully recessed like all the other ports, and the Librem 13 USB-C port is only slightly less recessed than that of the Librem 14.

I appologize for the error.

Could you share the link to the charger of your choice please? I need a second one to carry with me around. :wink:

I did not do any research on different USB-C laptop chargers. I went out to get a new printer and decided to look for USB-C laptop chargers while I was there. I only found one of these chargers in the whole store, and so I got it. It has a 60W USB-C port with Qualcomm Quick Charge 3.0 for charging laptops and a 5W USB-A port for charging a secondary device like a Librem 5 or PinePhone. The charger comes with a sturdy cable with USB-C on both ends for laptop charging, but it does not come with a cable for the USB-A port. I have not had time to test it very much, but it charged from 40% to 50% in 20 minutes while running several virtual machines in Qubes. It is small and light, so it would be great as a portable charger to take on-the-go. But I should repeat that I have not researched other USB-C laptop chargers and do not know how this compares.
