Nos casos que li estava sempre ligado a utilizadores que tinham tentado instalar uma qualquer distribuição de Linux. Pelo que entendi tem a ver com o sistema UEFI

Booting Linux via UEFI can 'brick' some Samsung laptops

Citar:In January 2013, a bug surrounding the UEFI implementation on some Samsung laptops was publicized, which caused them to be bricked after installing a Linux distribution in UEFI mode. While potential conflicts with a kernel module designed to access system features on Samsung laptops were initially blamed (also prompting kernel maintainers to disable the module on UEFI systems as a safety measure), experiments by Linux developer Matthew Garret uncovered that the bug was actually triggered by storing too many UEFI variables to memory, and that the bug could also be triggered under Windows using a custom-made program intentionally built to write a large number of variables to memory. In conclusion, he noted that conflicts caused by the kernel module had caused core dumps to be written to the firmware, thus triggering the bug

Tens de ver se existe algum update para UEFI/BIOS para esse modelo.
