Open Control Panel - in the upper right corner, if View by "Category" is shown, change it to "Small Icons" - then open "Power Options" (2nd column). Select "Balanced (recommended)", then on the left side of the window click "Change when the computer sleeps" (or 'Choose when to turn off the display') - Select "Never" for both the Display, & "Put the computer to sleep". - Restart your PC.
Hope this is all it takes to solve your problem.
If mouse remains untouched for a few seconds, my computer gets locked automatically. The message "picture image as appearing in start menu, below that my name svsabnis, below that locked.
and below that switch user." When I click picture image or my name display of whatever site I was, turns on. To overcome this problem I have set hibernate and sleep period as NEVER. But the problem persists. Any participants/expert may be able to advise as hoe to overcome this problem.
