I've a G560.
Yesterday it's running when suddenly shut off.
Than no life signal anymore.
No power button works.
No led light works.
I think my motherboard died, because AC cable is tested and works.
Do you help me in this situation?

The hardware manual would offer power checkout guide (page 21-22). Since the charger works or another working charger also fails, check to see if the laptop would still show any indicator light (battery led) when plugged in.
Here, we are isolating if the laptop can receive power to charge the battery so issue may be the internal of the machine. If no light showing up the dc in port can also be check and it would help bringing the laptop to any nearest service center to verify if the issue is with the motherboard or just the power port (connectors/cable may be loose).
I hope this helps answer your query on hw to proceed next.

I changed my motherboard. Now if It's switched on, lights are lit, but there is no screen and after few seconds, the fan running on full speed.

Did you order the same part number for the motherboard?
First thing is to make the machine POST (power on self test). Pressing caps lock on/ off should respond as one of the indicator that there is input/ output communication. This should show the led with a compatible mother board and working ram and CPU and power boards and cable.

Thx for a reply.
Yes, my new motherboards part number is the same with the old one.
When I turn on the machine, pressing caps lock or num lock do nothing.
Just black screen, cpu fan on maximum speed. No beep, no blinking, nothing.
Will it help you if I make a picture or video?

We hope to assume that you have received a working motherboard, then you can probaly check if the memory sticks are also ok.
Next is the fan and heatsink assembly making sure that it is on the right spot and this would include the CPU to include in checking.
This should at least narrow down the points of failure.
