Solved! Samsung rv509 - led is on but power button is not working

Solution
Are you sure it is the button? Do you hear any internal sounds when you try to turn it on? If so, but the display is just black/not on, then try the instructions included below. If, however, there are no other signs of life, then the problem could be a few things and I would suggest having it looked at by a tech (if not under warranty) or by the manufacturer (if it is still under warranty).

Try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on...

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.

You may also want to try hitting CTRL + SHIFT + WIN + B to try and reset your graphics driver as another possible fix.
