@xubu : non je n'avais pas installé tlp, je vais le faire.
@Nuliel : test bios = dans le bios, débranché et au bout de 5 min, craque tout s'éteint...ça semble donc un problème matériel? et pas ubuntu?
installation tlp faite :sudo tlp-stat donne :
laurenceetseb@laurenceetseb-HP-Laptop-15-bs0xx:~$ sudo tlp-stat
