DELL LATITUDE E6430 won't switch on

[reiwrit]

Hi, I have a Dell Latitude E6430. Whenever I press the power button, the HDD LED light flickers, then goes off but the screen stays blank. However the light to indicate that the power is on, stays lit. When I press the power button again, the fan whirs and the the laptop shuts off. I was wondering if anyone has had similar problems and how I might fix this issue.
Thanks

It sounds like it is on, just the monitor isn't...

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 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.
