Still boggles my mind that people praise ThinkPads as an option for those looking for repairability and upgradability while casually talking about the built-in BIOS whitelist designed to block all that.
To me that means an instant black ball.
It's cool hackers are patching this out, but this anti-consumer feature should not be present in the first place in something people recommend.
Sony laptops were the worst: Sony has elitist culture when it comes to miniaturization and engineering excellence, which manifests as unsolderable gapless tiny solder pads in case with PCBs. Fujitsu is better: they love to get creative with their own testing criteria that results in excessively hot laptops that relies on keyboard typing surfaces as heatsinks. Toshiba designers seem to be smart and rational people who understands that no one cares if they double sided everything. Dell is just thick and heavy while not particularly durable and occasionally being annoying with proprietary accessories. HP seem to have every hardware and software imported into their ERP and that can be annoying sometimes like having HP-only bugs.
ThinkPads don't have that kinds of things. They note on Hardware Maintenance Manual(HMM) that all removed screws must be discarded and replaced with their beautiful urethane coated and thread locked screws, and they still haven't made value of ~220 as default for `/sys/devices/platform/i8042/serio1/serio2/sensitivity`, and that's it.
Which other brands?
They only do it there, on the cheap-ass notebooks they don't care.
White-box suppliers/resellers like Clevo or Walmart, or more recent entries like Microsoft, Huawei, Razer, Valve, etc might not have it across the lineup. Whitelist feature also invites people break root of trust; that might be an alternate concern for those brands too.
Is this modularity mostly an incidental side effect of part reuse and corporate serviceability for Lenovo's benefit rather than ours? Sure. But hacking isn't always about what things were designed to do - it's about what they can do.
you can't just say this without giving us more details... MOAR!
Aside from sourcing the parts, the screen part was actually harder: this combination of screen, lid, and webcam is not officially supported, so the drilling and hacking I had to do for that was not documented. Unfortunately the foam tape I used to brace the screen in the correct left-right position seems to have slipped, as the screen is no longer properly centered... oh well!
Flashing the BIOS is also usually well documented.
I wish the BIOS flashing was not needed tbh, but at least it’s possible.
No BIOS whitelist, antenna connectors that run up into the screen where the front bezel is plastic (allowing good reception), and plenty of room for an adapter. Grabbed a cheap adapter and AX210 card and stuck them in there and it all just works and so now it's equipped with BT and wifi better than is in my 13-years-newer X1 Nano.
Nobody is selling computers that are fully open. Even Framework uses a closed firmware.
In our modern capitalist hellscape, you sometimes have to settle for the least worst option. The BIOS whitelist on older thinkpads is completely trivial to defeat, and apart from that they are incredibly durable and repairable machines. The T530 came out in 2013, and has been my daily driver for near 10 years, after buying it used for $100. I'd say that kind of longevity is more than worth the effort of flipping some bits in a BIOS image.
If you want to draw hard lines like this, then you've ruled out absolutely every machine produced in the last 30 years. Nothing is fully open. You simply have zero options.
If you want non-obscure HW you'll have to go back to pre-microcode days of processors roll out your own.
