My laptop acer aspire 5 a 515 57 t32 screen dont turn on while i push power on button, although keyboard lighting turns on. Lately when i open unity project screen mulfunctions and starts lagging so i have to turn it off by pushing poweroff button a few seconds, then sometimes laptop turns on while i turn it on, sometimes there appears a blue screen saying you need to restart your pc, sometimes even acer logo doesnt appear on the screen when i turn it on. But only after a few times of trying it opens. Now today again, i opened unity to check if it will mulfunction again, it did unfortunately, and i had to turn it off pushing power off button a few seconds and it turned off. Now i cannot turn it on again, keyboard lightning works but screen is black. Can you help me?

    The symptoms that you are getting with your A515-57 is because the eDP cable is either damaged or its plugs at the screen or mainboard are lose or faulty and not making a full connection with the mainboard to give you an image (btw I’ve got the same laptop and mine works 100%) the eDP cable does wear if you open and close the laptop allot.

    Before you check the eDP cable and disconnect its plugs YOU MUST DISCONNECT THE MAIN BATTERY AND THE DC ADAPTER PLUG so that the laptop has no power (as if it has power, you will cause permanent damage to your laptop) if the eDP cable is disconnected while the laptop is powered.

    Check the eDP cable condition and its plugs if their pins are not shorted or even change the eDP cable for a new one, see if that fixes this on/off problem. If not, then you have a main screen fault and you need to change the screen for a new one, see the part number of your existing screen as it should be one of the screens listed below, good luck.
