I found there is an update for my SSD*. As my XPS13 sometimes hangs on thaw, I wander if this update could help. I read it fixes issues about power management, but nowhere I read it targets ubuntu.
Also, can I use the iso file to burn a usb stick instead of a CD?
Sorry, I posted a bad link above. My SSD is a LMT-256M6M with firmware DM8110C and there is a DM8110F, A05 available here : www.dell.com/.../DriversDetails
