Samsung just re-entered the laptop market in the USA a few months ago. I didn't find that model here.
So call your Samsung local number and ask for service.
My Samsung NP-X360 laptop won't power up. LCD light on AC adapter light comes on nice and bright but if I connect the adapter to
the laptop, the light dims down and starts to blink. With or without battery. My wife leave this laptop on all day. Is it fried. Is it worth repair?
