In power settings I click advanced settings and "sleep" and then "Hibernate". I put in the time in minutes I want (ex 180 min). I click apply, and it appears to stick. I see the 180 in blue. However once I close the advanced power setting window and reopen it, the two (battery & plugged in) hibernate settings are back to "never." The "sleep" settings do save. I tried this on the "Dell" power plan and the "Balanced" one and neither works.
Does anyone know why? Is there something about the build of the 17RSE that means it cannot be configured to hibernate? Would it have something to do with the solid state drive?
