My laptop is Acer Aspire 5 A515-51g
When I press the power button the blue light turns on but the display is black
The Hard Disk also running
If kept on for few minutes the fans also is works and heats a bit as used to while normal usage
I even tried connecting to an external display but nothing shows up there
Can anyone help me fix it
HISTORY:-
My laptop is 1yr 2months old(so out of warranty) 
It has its motherboard replaced 2 times and keyboard 1time.
Since then it was working just fine for about 7-8 months
