Help me with my laptop?

I have a problem with my laptop and although it shows no picture but the led is still lit and you once again briefly hear the fan

would be nice if you continue to help me

Well, there can be several reasons:

Laptop graphics card defect
Laptop mainboard defect
Laptop Ram Module defect
If you are lucky, the battery is empty and need to charge via AC adapter.

I've seen sometimes where it can be synonymous with mainboard battrie

Do you know if it's true or not

Remove the battery, then the PowerTaster 10 sec. Press, then the battery back into the notebook and try if he goes to.

Can also voices, but with many laptop is also without CMOS battery still BIOS start up, stop you have to set the clock again and again after restart correctly.

Do you have HDMI cable and another device to which you can connect your box?

Do you have the second screen image, then it is clear that the display is over.
