The Macbook Pro 11,1 (retina) I have been using with Linux for years as my main personal and work machine, recently developed multiple hardware issues:
- the USB3 internal hub was dying now and then, thrice a week
- the battery was down to 70% of its original capacity, 3 to 4 hours.
- the screen coating was starting to go green and peeling off AGAIN
It was a great everyday laptop that I met my needs perfectly:
- A great feature set: great connectivity, great screen, thin and compact, not too heavy but stable enough … Kind of a unique package.
- The keyboard was OK, I appreciated that the keys were relocatable to a dvorak layout.
- Fast and powerful enough with an (now old) i7 CPU, 16GB of RAM, 512GB SSD …
I have been using thinkpads 15 years ago and I still own 2 X220, but they weren't as good as this rmbp, so I setup one for my dad and the other as a live spare (syncthing and git make it very straightforward).
I waited a few months before deciding to replace the rMBP, trying to fix the USB3 / XHCI issue to no avail. Every now and then, the laptop USB hub would just come out of suspend and die, forcing me to ssh in and reboot. This problem seems part aging - part linux support. Anyway, the day it failed twice in a day was dies irae and I decided to replace it. However, buying is something I don't like too much:
- I have this feeling that you can never truly get everything as good as the thing you are replacing.
- I don't have a collector mindset. Everything I own has a weight attached to it, only relieved by its usefulness.
- I usually buy stuff "used" because I usually don't need "new", more power, storage, … and I don't like the "new" shops, I prefer the "second hand" ones :)
- I like to be able to act on the things I buy, may it be replace the car fluids, change the plane blades or replace the laptop internal battery.
So I started a week long research … actually no, I just ragequit work early, looked at the offers from the refurb shops on my way home, jumped out the tram, picked a lenovo t470 for 350€ that looked OK and arrived home. 30 minutes. You can't go wrong with a lenovo T/X series.
1.1 And that's it?
Well not exactly.
I also bought, new, from amazon a battery set, a new keyboard and some RAM. Buying "used" laptops is just like buying "used" cars, you may need to change some wearable components.

I was pretty pissed when I bought this laptop and didn't have much expectations other than "just work good enough so I don't have to suffer this rMBP anymore".
This laptop can host two batteries and has great power management.
I bought a new
61++ 9 cells external battery and an internal battery (4 cells), for 100€ on Amazon :

Now, I am typing this on a plane between Paris (France) and Bengaluru (India), and after 4 hours of usage (music playing and text editing mostly, at minimal settings):
The battery reports a discharge rate of 4.42 W The estimated remaining time is 17 hours, 17 minutes
It was around 21 hours when both were full. This is truly amazing.
Moreover, you can hotswap external batteries since the integrated one is always in. Stupid thing though: the internal battery is the first to discharge!@# And eventually, it stops when the internal battery goes dry.
2.2 The keyboard
Thinkpad keyboards are great. I like the old thinkpad keyboards (X220-) more than the new one (X230+), but they are still better than my previous rMBP which themselves are much better than the new macs clicky and buggy flat keyboard.
Anyhow, this is a pleasure.
My mac had this relocatable keys feature than I really enjoyed though as I use dvorak. Dvorak is a reshuffle of a qwerty keymap (the non-letter keys remains the same :
[!1]...[)0]). So, pop out and in the keycaps of a qwerty mac, and benefit from a dvorak mac!
Thinkpads are unfortunately not build this way, since they feature the MIGHTY TRACKPOINT so you either stick stickers on the keycaps or type blind. I set
right control key to switch between layouts, so if I need to, I can still borrow my laptop.
% cat /etc/default/keyboard XKBLAYOUT="us,fr" XKBVARIANT="dvorak," BACKSPACE="guess" XKBMODEL="pc105" XKBOPTIONS="grp:rctrl_toggle,compose:lwin,grp_led:scroll,ctrl:nocaps"
Emacs uses the
hyper key in org mode for some convenient actions and well, there is no such thing as an hyper key on a keyboard so I dedicate the left control to be hyper in emacs, capslock being remap to control. This is a bitn messy.
fwupd fetches updates published by lenovo to the
fwupd repositories (some kind of consortium).
I hope to fix this battery discharge sequence soon.

Yeah, well, please take care to install in EFI mode. For some reason, the BIOS on mine was set to legocy boot mode only … Better reset this BIOS anyway.
I have been using "lightweight" environment for two decades now, mostly a window manager, terminals and a web browser. And quite a lot of other programs around to handle media keys, screensaver, session locking, app launching, energy saving, wifi management…
OpenBSD provides a great out-of-the-box experience on thinkpads, where energy saving, medias keys and more are just provided as base features, no setup required –and I am not actually sure– possible.
The result is just GREAT:
- the media keys just works as expected, even micmute and such (I can drop my custom
- the system locks the screen with a password (so I can drop
- the keychain and agents work, to mount encrypted drives or connect to ssh servers
- the external monitors setups is remembered (so I can drop my autorandr scripts)
Settingsapp is fine
- everything is as snappy as before
