My laptop is a lenovo yoga 2 pro. I looked over at my laptop and saw tbat it was off, so I didn't see how it turned off. I thought maybe I'd forgotten to plug it in and it ran out of battery, but it was PLUGGED IN. I unplugged it, took the battery out, held the power button down for a while, plugged it back in, and tried turning it back on. No luck. Tried doing the same with the battery back in. No luck. I took the battery back out, and while it was out and I was inspecting wires and such, the laptop turned on and started booting up...and then turned back off and wouldn't turn back on, though the orange light (it glows orange when there's low battery and white normally) next to the power button always stays on as long as it's plugged in. I gave up and left it alone for a while and then tried another reset. Without the battery in nothing happens but the orange light stays on. With the battery in, the laptop powers up, as in the keyboard backlight comes on and the right fan turns on, but nothing else happens. The screen doesn't turn on, and the main power light ON the power button does NOT light up. I haven't seen that light come on at all since the laptop died. I don't have another screen to test with. Only other screen is the phone I'm typing on now. Any suggestions?
