A GNU+Linux laptop that Respects Your Freedom!

We now also sell the smaller, more portable Libreboot X200.

Did you know that most modern Intel and AMD computers come with backdoors implanted by the NSA and other agencies? You do now, and it isn’t pretty. And it’s getting worse. Since the Snowden revelations, we know that most computer products contain backdoors or have insecure software with exploitable bugs. Manufacturers intentionally insert insecure backdoors for profit, putting your company at risk of data theft, corporate espionage or worse. The Libreboot T400 from Minifree changes that!

The Libreboot T400 from Minifree is a business-grade, secure owner-controlled laptop that safeguards your privacy, security and freedom. It sports a dual-core Core 2 Duo P8400, Intel GMA 4500MHD graphics and supports up to 8GiB RAM, making this an ideal high-performance workstation with the Intel GM45 and ICH9 chipsets. It runs 100% entirely on free (as in freedom), libre software, from the BIOS, right up to the operating system, drivers and applications. It comes with the free (as in freedom) Libreboot BIOS replacement, and Trisquel GNU+Linux operating system, which is FSF-endorsed.

Your Libreboot T400 obeys you, and nobody else! The Libreboot T400 comes without the Intel Management Engine or AMD PSP!
