my daily driver is the Thinkpad T400, the most powerful laptop that you can libreboot to remove completely the proprietary Lenovo BIOS in favor of a fully open source BIOS. The distro on it its Parabola GNU/Linux-libre: a 100% free distribution.\
I have done a series of mods on this machine, and more are to come. What follows is a list of some useful resources on the T400 itself and the mods compatible with this device.

## Resources
- tons of info on the [Thinkpad T400](https://mcdojf.wixsite.com/t400)
- [Thinkpad T400 manual](https://thinkpads.com/support/hmm/hmm_pdf/43y6629_05.pdf)
- [Trustworthy site](https://minifree.org/) that sells Librebooted devices (including T400s)

## MODS
Here are the most common mods you can do on a Thinkpad T400
### Libreboot 
The Libreboot project provides free, open source (libre) boot firmware based on coreboot, replacing proprietary BIOS/UEFI firmware. I made a guide on how to do that. It's [here](https://bytemeifyoucan.lol/p/my-t400-libreboot-guide/).\
The Official Libreboot site is [this](https://libreboot.org/). The Thinkpad T400 official page is [this](https://libreboot.org/docs/hardware/t400.html).
### Quad-core mod
It is possible to install a series of quad-core processors on the T400, taking advantage of the fact that they have the same socket of the dual-core Core Duos that come with stock machine.\
You will need some soldering skills and decent amount of patience. A very well done guide can be found [here](https://thonkpeasant.xyz/guides/other/quad.html).\
The original post can be found [here](https://thinkpad-forum.de/threads/core2-quad-mit-coreboot-libreboot-auf-t500-wahrsch-auch-t400-benutzen-beta.199129/). (in german)
### Cooling mod 
TODO
### bluetooth
the bluetooth of the T400 is 2.1, you can easily upgrade the bluetooth 4.0 by swapping the card located behind the LCD front bezel
### Ultra-bay mod
I am currently working on a variation of a mod I have seen floating around the world wide web. It's [this one](https://hackaday.com/tag/thinkpad-ultrabay/). In the article the laptop used is the T420 so I changing the 3D printed part to fit the T400 ultrabay.\
More info and **maybe** a guide will appear in the future, depending on how much time and effor i want to waste on this idea.
### Express Card slot
The T400 Express Card slot allows you to slot in any compatible Express Card 54, i think the most used card is the one that gives you one or two (depending on the model) USB 3.0 plugs, with up to (i think) 5Gbps transfer speed. Cool shit.
### Parabola GNU/Linux-libre
The distro i use on my librebooted T400 is Parabola GNU/Linux-libre, a community-driven, "labour-of-love" effort to maintain a 100% free (as in: freedom) operating system distribution that is lean, clean, and hackable.
A guide on installing parabola with a encrypted root partition using luks and open-rc could be created in the future.
### External WiFi antenna
Still have to do some research on this to understand if it makes sense or not.
