I upgraded my notebook from 8.1 to 10 then i resetted it. But i faces a problem about sleep mode. it can go into sleep mode and sleep mode light winks but when i wake up it, it doesn't continue where it left off, it boots from the beginning as if i press power button. i don't find what causes that problem and any solution. My notebook is x550lc, its bios and drivers is up to date. Could you help me pls?
