Pressing power button turns on keyboard light but nothing else happens

crwdns2934249:0crwdne2934249:0:

When I press the power button, the keyboard lights will enter some kind of loop, where they turn on and off repeatedly, but nothing else happens, no image on screen, no boot messages or image, nothing.
I tried replacing the battery with a new one, and tried using a different charger, and still have the same issue.

+A late update: ~1 month after resolving the issue, the laptop started having similar problems again. To solve them, i just removed 1 of the RAM modules. Haven't had any more issues, apart from a defective battery. So it seems the problem was the RAM.
