Your story is a bit light so let's see if the Cnet Samsung Forum can help. Be sure to put in ALL the details. Age, the call to 1800SAMSUNG and your transaction number.
If the charger is not a Samsung you may want to tell exactly what you used. I know most makers void the warranty if you don't use their parts.
Hey Im having this issue with my laptop its a samsung np-q430- jsb1us and I was using it and all of a sudden the battery stoped saying it was plugged in but when i shut it down the battery light on the computer blinks yellow and when i take the battery out its a solid green light but it wont power on and i just got this charger yesterday. The charger worked fine till now and it is still registering that its plugged into the computer but not doing its job the yellow light is supposed to be solid when its off and battery is in. can anyone assist me here?
