I have a Lenovo Yoga 3 Pro that won't turn on either just on battery mode or with the charger plugged in. Charging light on the Power On button lights up when the charger is plugged in and remains on when I charger cord. After pressing the Power On button for about 10 seconds the keyboard light flashes but goes straight off. Nothing appears on the screen at all. The motherboard fan works fine and remains on.
There is no SSD installed at present, but I think the system should try and boot to BIOS level and display message to the screen. But nothing on screen at all.
Any ideas of: 1. what the issue is and 2: how to fix it?
