Did you try starting it without the battery? Try a different power supply? If yes, may be the power connector on the motherboard or the motherboard itself.

Yes i did that without the battery everything tou think the power connector ?You say dc jack power? or another thing? Because dc jack power is OK I see the orange led light when I put the charger.

If the light on the lapotp lighs up, it's getting some signal. Cheapest thing to try would be a new power supply. After that you need to look at a new motherboard.

you didn't understand me,it lights up when I put the charger into dc jack power that its charging.

you didn't understand me,it lights up when I put the charger into dc jack power that its charging.

I do understand that the light is on, but that does not 100% mean that it's working. You only know that the light is working not that it's charging.

If you don't want to try a different charger, you can go right to replacing the motherboard.

Did you try to pull the BIOS battery, have you tried disconnecting the LCD panel and using an external monitor?

 

[Shpend Berisha]

Yes I tried to pull the bios battery no I didnt try to check with an external monitor because It doesn't power on.

Does the laptop have 1 or 2 sticks on RAM?

two sticks of ram wone is behind the laptop and other is inside but I tried to change the ram positions everything. and when I tried all these I saw a new thing I saw green light on power button only 1 second.
