Ey mates, I've got a Lenovo Ideapad N680 here that was working perfectly, cared for like a golden ingot, that suddenly only turns on the fan and the powerlight. I disassembled it, checked everything, it's all in order. I can turn it on with the power button, the fan, HDD, and DVD ROM turn on but nothing on the screen and hitting Numlock doesn't toggle the light. If I hold the power button, it turns off as expected. Please help.
I've tried removing the HDD and RAM cards hoping for something else to happen (a beep code, for example) but no luck.
