Thinkpad x200 or x200. Yeah it's old tech but with coreboot it loads faster than a top-line gaming computer. No need for graphics cards if you're not gaming. I sold my Asus vivobook (with excellent dedicated graphics etc) and made the switch to a corebooted x230. Everything on it - every driver and every firmware is FULLY open source. No blobs, no unknowns and no mystery code running on it.

You may also want to research the intel management engine back door all modern CPUs have. Though system76 says they disable it, you're still relying on non-open source drivers for your graphics, Bluetooth, WiFi etc.

I took the plunge and am 100% satisfied. Bye bye windows , hello full control and as a plus, the x230 is MUCH faster and snappier than my old gaming laptop.

Only downside: it's a battery hog, I can last 4-5 hours on battery. I do have my laptop plugged in most of the time. I am okay losing some convenience for full control and peace of mind.
