No power to samsung NP R519 POWER BUTTON NOT WORKING

SOURCE: speaker volume like small baby

To fix the volume control re-install the drivers of the laptop and in the right lower corner you will see a speaker like symbol where you can control the volume. Increse the volume from there.

Thanks

SOURCE: why wont my samsung np- r519 switch on

The power supply unit might be bad cannot specifically isolate the problem you may have to replace the prong pin on the mother board where the power unit plugs in this is a common problem with lap tops and because over time the solder gets weak and brittle and breaks a solder point this could also be an issue. I suggest that you take this in and have it looked at by a professional. Have them check the power supply unit and the board pin. Thanks for using FixYa! John

You say it isn't charging, but will it run off of AC power? If it isn't getting *ANY* AC power, then it might be the female end of the power jack on the laptop. If it will run on AC, the culprit is likely to be a battery that needs replaced.
