Tehnoetic TET-T400 laptops are refurbished Lenovo ThinkPad T400 laptops sold under our own brand, with a guarantee that the T400 we ship is free software compatible, preinstalled with GNU Libreboot fully free BIOS replacement and a fully free distribution of the GNU operating system; we can make no guarantees that other versions of the T400 are fully compatible with free software.
The Tehnoetic T400 is a refurbished 14.1″ fairly modular/customizable Lenovo ThinkPad T400 laptop preinstalled with Libreboot, the fully free BIOS replacement, and with a fully free GNU/Linux operating system at customer's choice (Trisquel, Parabola, Dragora, gNewSense, etc). Enjoy the freedom of having best control of your computing, privacy and security by using the Tehnoetic T400.
Libreboot is the fully free BIOS/UEFI replacement endorsed by the FSF. It is based on Coreboot, having the nonfree parts removed and better build system. While most people tend to overlook the importance of having fully free BIOS/UEFI and bootloaders, emphasizing only the need to have a free main operating system, these lower layers of the computer can contain backdoors and security vulnerabilities which have the potential to violate user's freedoms and privacy.
However, the control over your computer with a fully free BIOS is incomplete without a fully free GNU operating system, endorsed by the FSF and other free software organizations like Ceata. A fully free system doesn't preinstall, host or recommend nonfree software. Thus users can feel protected from the dangers of proprietary world and also feel part of the community which contributes to the advancement of the free digital society. The society which Richard Stallman has envisioned and has been fighting for for more than 30 years.
We at Tehnoetic are doing our best to offer you the best free software compatible T400 which reaches its maximum potential. Thus, we replace the nonfree firmware 2-antenna Wi-Fi card with a free software compatible 3-antenna Atheros AR9380-based one, we add an internal Bluetooth USB adapter and we upgrade the memory to the maximum capacity of 8GB. Optionally, we offer a caddy adapter at no cost for the common case when you'd like to use a 2.5'' SSD/HDD drive instead of the detachable DVD/CD RW drive.
