My Lenovo Yoga is not turning on, no screen lights, key board lighting, or light next to power button is on. But when I plug it in the charging light turns on (see pictures). I have tried re-seating the ram, taking out the ac adapter and holding the power button for 30 seconds to a minute, and took out the battery pin and tried the same but to no avail. It still doesn't work. But, when I hold the power button with the battery plugged in, this fan on the back turns on for a few seconds. There isn't any CMOS battery that I could find, even on the other side of the motherboard. I also used two cables that work with another laptop, and still it wouldn't turn on. The One-Key button does not work either.
Please do not ask me for the model number because I really do not know it. (the sticker on back has been ripped off.)

Is there an FRU number anywhere? Maybe on the motherboard or even the battery?
