Recently I was using my Sony vaio e series laptop (it's about 4 years old) and everything was working fine. The next time I tried to turn it on the keyboard lights turned on the fans started spinning but the screen showed nothing but a black screen and it stayed like this for about 30 seconds then it turns off, Im pretty sure it's not the battery because it does the same when I take it out and plug in the charger. Has anyone got a solution, should i try get it repaired ( The warranty has run out) or should I just scrap it and get a new one? Any help would be appreciated, thanks
