I have lost the function to put my computer into stand by mode by either closing the lid or turning off computer in the start button section. I have gone into the power and performance menu to reconfigure the power options and the options to put the computer into stand by, hibernate or shut down have all dissappeared from the drop down list.1 person needs an answerI do too
