Lenovo thinkpad e560 powers on but just black screen
Texto:
Hi,
my Lenovo thinkpad e560 powers on but i see just a black screen. I don’t even see the system boot up to bios. The system is definitely booting up and i hear fan spinning but just a black screen.
What i have already done:
# Power on with and without ac.
# Power on after removing the bios battery
# Power on without ram.
# Power on without hdd.
# Power on and connected the notebook to a external monitor.
Can someone give me a advice ?
Thank you in advance .
