My Dell Latitude E5500 screen won't turn on

[mem4961]

My Dell Latitude screen will not come on it stays black. It came unplugged and turned off because the charging
port doesn't work to charge the battery. There are lights and I hear the tone that says it is powered up but nothing on screen

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.

I left the computer off all night and it turned back on just fine this morning.

That is rather odd. I would keep an eye on it. Let us know if it occurs again.

My Latitude E5500 does the same thing. After leaving it alone overnight, it will turn back on!?$#&!
