I have a Levovo Ideapad U310, PN 59351642, 13.3" Ultrabook. When the power button is pressed, I can hear the CPU fan was on but there was nothing on the screen. I verified that the disk is working. I can attach the disk to my external drive and it is working file. I suspect that the mother board is bad. But I need to confirm this before ordering a mother board replacement. There are other components such as the LCD screen or the CPU itself might be bad. When I turned on the power, I tried to enter the BIOS set up utility by pressing Fn-F2 but there was still nothing on the screen and there was no sounds or beeps. I have tried the "onekey rescue" but this also did not work. Are there any other tests that I can perform to be certain that the mother board is bad and all other components are still okay? Any helps / suggestions are greatly appreciated. Ken

Same here. Mobo is faulty.
- press power and caps lock flashes once
- front battery light is on and funtions normally (flashing amber for charging, white for charged)
- front power light is white, as normal
- power on button is on, as normal
- nothing on screen, no backlight, completely black
My part number ends with a 7, meaning i5 CPU - so it's not a CPU specific issue but a common issue between models, meaning motherboard or something on the board like the GPU.
