It's not an answer, but i too wanted to request solution for similar problem, Dell Inspiron 14
Actually for last 2 days when i was trying to shut down laptop from start menu, it was not happening and i then once i shut it down from manual key button. Next day when i switched it on, then found only background screensaver is coming and there is not any icon/ login page coming... can u please HELP I have a urgent PPT to prepare on that .. even if i am swiching off and on again... it's the same issue.. tried pressing F1 and F2 and then found some options - but not sure what to do..
Please note that - "earlier for many days - it was showing batter needs to replace" . Hope this proble mis not connected to battery
What you mean "Only a screen saver"?
Has your Windows booted?
When you press <Caps lock>, do yo see any LED changes?
When you plug an USB flash disk, can you hear the sound from Windows indicating thtaa?
