Laptop shots off when I move the screen backward. fixable?

My Lenovo S510P Touch shuts down whenever I move the screen backward (increase angle between screen and keyboard) but remains on if I don’t move the screen or when I move the screen forward. The computer can be powered on no matter what the angle between the screen and keyboard is, but once its on and booted up, I cannot move the screen backward or the power would be gone. Is this a cable problem or a motherboard problem ? If cable, is there a good link to show me how to change it ? Any advice will be appreciated.

The screen cable runs through the hinge so it sounds like the cable has frayed in the hinge and is getting shorted. You need to dismantle the screen and remove the whole screen and back from the laptop and examine the cable. Any of these cables can break inside so it is probably best just to completely replace the cable thatruns through the hinge section.

I thought the cable was the problem too until I called this local computer store and told the technician the problem. He said because the computer was powered off, not just dark out, it was a motherboard issue. Does that sounds right ? I will try to open it up and check on the cable and hopefully it is only a cable issue.

Ray L this sure sounds like a bad cable. Download the maintenance manual from here and check the cables for any break in the insulations or any other damage

I reckon this is cable. If it is the part of the cable that powers the screen it could well shut down the whole PC. That would probably short out the power supply. The fact that it trips when the screen is pushed back implies that the cable is getting tighter through the hinge and then shorting. If the screen is moved forwards then the cable slackens. I don’t know this laptop but You may also have to remove the cover that sits between the screen and the keyboard to be able to remove the screen covers. Again I don’t know the laptop but the screen bezel should come off with some GENTLE lifting of the bezel that touches the actual screen so that you release any clips. Use your fingers if you can so that you don’t damage the screen. Make sure you have removed any screws first.
