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

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.
