Solved! Asus laptop (X542UQ) turns on when plugged

[ElPerroMalo]

Hello, mi laptop turns on when the charger is plugged in (automatically) but there is no image, only black screen and the fan makes some noice, I tried resseting the BIOS+CMOS (there is no battery for BIOS, so y do it connecting a wire in the JRST2401 jumper), but nothing works, any idea?

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.

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

Nothing works, still no image, and I can't clear the CMOS, maybe MOBO is dead, how can I know?

So it won't show on an external monitor either? Did you try it on an actual monitor or something else?

External monitor, on hdmi and VGA ports. Still black screen.

Then it is either the GPU itself or the motherboard. You are going to have to have it looked at. Either by the manufacturer, if under warranty, or by a local tech.
