You didn't. Bay Trail is an Atom and there has never been a ThinkPad T with an Atom chip.
Not to mention that the 40 generation didn't have a T540. It had a T540p with various Haswell CPUs from cheap i3 up to i7 4700MQ. ThinkPads always ran wonderfully with Linux. It is the only with a p, all other T5x0 machines from the T500 to T580 didn't have a p (performance) postfix.
I do not think there was any ThinkPad ever for that matter with an Atom chip but here I might forget some bad apples. But certainly not in the T and X2... series, these are flagship business class machines.
Maybe some Ideapad? Yoga? Flex? whatever 2-in-1 -- but who cares about those.
I'm going to extend OP the benefit of the doubt on the model name here and say this: it sucks that Lenovo have diluted the "ThinkPad" brand and it sucks that they didn't remove the bad models from their Linux compatiblity list.
On the flip side, I think ThinkPad workstation laptops (T-series and above) are still safe for Linux. Just avoid the convertibles and tablets as well as the budget-range Edge series, which are frankly bad computers overall.
Does that more satisfy you my hair splitting, persnickety friend?
I'd guess that if you came up with a link[1] showing that the T540p was indeed sold with a Bay Trail processor, 'chx' would apologize profusely, publicly eat his hat, and probably come over to mow your lawn. Alternatively, if for some reason you misspoke as to which processor generation it had, you might consider making the world a slightly better place by correcting your error and apologizing for the apparently trivial bit of misinformation.

This merited a strong reply because contrary to this allegation, the rule of thumb is to recommend a ThinkPad T or X for someone looking a Linux laptop.
You can accuse an old Porsche 911 SD of having problems with the front engine but people will be quick to point out that a) Porsche 911 only had an SC and not an SD version b) the Porsche 911 engine is in the back.
It's a shame Lenovo's documentation is inaccurate though!
The ThinkPad was once venerable brand, but I've lost all respect for it - at this point I'm probably just going to buy a MacBook Pro and send the W540 back to the office because I'm tired of playing the Linux compatibility game on modern notebooks.
Former ThinkPad fan, current MacBook user: I am likely to buy a Dell for my next laptop. Dell expanded the range of machines that they will preload with (Ubuntu) Linux last year, and were the first big vendor to sign on to the Linux Vendor Firmware Service, so that supported computers can get easily get firmware upgrades.
Yeah, I definitely should have qualified that I probably would not get an XPS, because there seem to be consistent issues with that line. That's why I'm pleased to see that Dell have expanded the number of ranges that they offer Linux support on: hopefully there will be some good models at the time that I need to buy a new machine. Or I could buy an unsupported model: none of the ThinkPads that I used had Linux support from the vendor.
I use an HP Spectre as my Linux laptop now. Everything worked on a modern kernel out of the box and the quality seems way better.
I know that Martin Wimpress, the Ubuntu MATE lead, sometimes uses a Spectre. They look to be quite a different thing to what we might expect from a HP laptop.
I certainly didn't have any complaints about them. Absolutely stay away from consumer models, obviously.

My Wi-Fi and battery status still don't work. I use a Wi-Fi dongle at work. :-P
VMWare's stupid kernel modules are always breaking in one way or another as well, plus I never get guest 3D support because of the switchable graphics in my laptop and I just cannot be bothered to fight and fight to get it to work. I tried using gnome-boxes instead for a while, but audio inside the guest would constantly get garbled and have cuts, support for guest drivers beyond VirtIO disk/network was hit and miss.
I've got more, but I don't want to make it into a rant about the state of the Linux desktop - because for all the problems I have I still love it, but I need a computer and software that works smoothly out of the box because I have work to get done.
I picked up Slackware and FreeBSD a long time ago and had so much fun plus found a career.
I finally through in the towel with Linux as my main machine a long time ago and went back to Windows as 7 was pretty good.
With Win10, I've tried to deal with both VMs and WSL, but once I got a MBP there was no turning back. I simply don't have the time or patience to deal with the issues Linux now has.
Don't know what the solution is. Perhaps dump Systemd and the rest of RedHat's decision.
Or maybe Redhat, Suse, or whover could just get one disto working perfectly on two or three hardware models a la Apple.
But not happy with how things have turned our with Linux on the desktop.

The closest thing to an issue is the poor battery life - but this has been my experience with all laptops and Linux.
I can't comment on the W540, and I wonder if it is that different compared to the W541.
Not to defend Intel but that was 3 generations ago; I would certainly consider a Gemini Lake for my next nettop - where media-pc quiet is more important to me than performance. (provided no showstopper bugs exist!)
I wonder how ChromeOS avoids(fixes?) both the above said audio issue and the cstate issue mentioned by you.
Do any options have open boot/something close?
As for open boot, I understand the X220 supports both coreboot and libreboot, but I don't use either, so I can't comment on it in detail.
I would like to get an 802.11ac card for it at some point and that's about it. It came with a 6-cell battery with 70% capacity left, and I've put a new 2Power 9-cell battery in it, getting around 6-7 hours battery life as you say. I would sort of like to have an external charger so I could always have both batteries topped up, but they seem to be rare as hen's teeth.
In my opinion, the X220 is probably the best Thinkpad ever made. The i3 isn't a problem, I used a T42 for years and years despite its slow-ass Pentium-M, and I only sold it because a lot of Linux distros started going 64-bit only.
I have bought a couple of newer Thinkpads but they end up reverting to my x220. x230 is almost as good but doesn't have the old school keyboard.
On reddit.com/r/thinkpad there is huge following for moding them.. My only recommendation is to ensure it you have an SSD and load up on RAM.
I'd love to find one damn laptop that we know works well.
By saying that, the 2018 generation of ThinkPads finally includes excellent panels. If you get the new X1C or T480(s), you can choose a bright IPS panel with a good resolution. With the old ThinkPads, especially X220/X230 you just need to be VERY sure you DO NOT get the TN panels.

The display is vastly superior. Everything is more crisp, and it is brighter.
The X220 is still fast enough for Chrome / YouTube / Netflix without spinning up the fan. Running a high res external display is a bit too much though; the fan kicks in most of the time.
Personally I care more about ruggedness (my X220i is my travel computer) than color fidelity. Compared to my old Acer Chromebook 13's absolutely horrible TN panel, the one in the X220i is actually quite decent.
Still, from what I gather the IPS panels suck a bit more power than the TN panels (not a huge difference, though), and for my use (travel PC getting lugged all over the world in hand luggage) I'm primarily interested in ruggedness and battery life. I use it to browse and read email, with the occasional Youtube video, not for anything color critical. I would be much more interested in upgrading the mediocre built-in speakers, apparently you can use the speaker from a Nexus 6P for a nice boost in volume and quality.
Thinkpads can also support not charging the battery to 100% / over-cycling it, which can help prolong battery lifetime:
sudo modprobe tp_smapi
echo 40 | sudo tee /sys/devices/platform/smapi/BAT0/start_charge_thresh
echo 80 | sudo tee /sys/devices/platform/smapi/BAT0/stop_charge_threshI am not planning on changing or upgrading it until it dies.

It’s fine, but my work laptop is a 15” rMBP and I know which screen, pointing device and battery life I prefer.
Install of Linux mint was simple and it’s been running well with no issues.
Pretty much nothing to do with that. It's been years since IBM does not own Thinkpad anymore but Lenovo was perfectly able to provide proper Linux support up until recently.
I bought a T540 3 years ago that shipped with a Bay Trail processor. This processor was absolutely unusable on Linux due to this bug (https://bugzilla.kernel.org/show_bug.cgi?id=109051). Even setting max cstate to 1 resulted in regular freezes.
Not only would Lenovo not accept a return of the laptop, I could not even get them to update their Linux compatibility page to warn other users!
To this day:
- The cstate bug is not fixed, and running Linux on a Bay Trail processor will cause lockups
- Lenovo continues to recommend laptop versions that are flat out broken on Linux (https://support.lenovo.com/us/en/solutions/pd031426)
So be careful!
