I have a serious problem at these days.
First of all, windows version (7,8,8.1,10) does not matter (i tried all), that was completely caused by laptop.
When I shutdown computer, after a while cooler fan turns and never stop. I want to boot-up again, and I press the power button, but pc does not response. DELL logo never shows up.
To boot-up again I have to press power button for 4-5 seconds to cut electricity.
I shutdown my laptop at night, when I woke up the battery is completely finished (%0 or %1). Never warm me "Critical Battery, to continue press F1".
If anyone knows why this happened or the solution, please help me asap.
