Laptop Lenovo G580 turns on for 2 seconds and off straight away

[Skyren]

My laptop Lenovo G580 purchased somewhere between 2010 and 2011 was used for 2 years or so, since sink tub was broken and didn't hold screen. It was in kind dark place until twoo weeks ago when I suddenly found it (working). I managed to purchase broken parts online + extra 4 GB of RAM. I did reassemble without any problems like it was but it won't turn on, not even screen, not even fan, nothing... just led is shinig for 6 seconds after release of the power button. I also did 1 minute stuff with power button, but it just turns it on for 2 seconds (mechanics) and off straight away and screen doesn't even flash. What could be the problem? Any solutions? Since I tried every that is free out there on mr. Google and none of them were accurate nor working.

Much of thanks

Hi, try without the new RAM, maybe it is defective.
