I have this Lenovo B460 for more than a year already.
What happened is that, When the laptop is turned on, the screen remains completely black/blank and the cooling fan starts running at full speed.
After pressing the power button, it doesn't show anything, not even the BIOS screen, just a blank black screen.
I've also tried to remove the battery, hold the power button for 30s and plug the power cord back in... Same thing laptop turns on but screen is black.
I tried connecting my laptop to my PC's monitor using HDMI cable, it worked... Laptop turned on my pc's monitor.
I haven't changed anything inside my laptop or unscrewed it.
Any help would be appreciated.
Many thanks.
